That is, the temperature rise of the connecting member 3 often occurs due to the contact portion of the connecting member 3 with the plug blade 911 as a heat source. Therefore, the detection point P3 or the detection point P4 provided on the connection member 3 is selected from, for example, detection points P101, P102, P110, and P111 that are close to the contact part with the plug blade 911 on the connection member 3.

- the characteristics of the holding member (terminal block 45) are affected by heat and the characteristics of the holding member change. (Including alteration, discoloration and deformation). Therefore, the detection point P1 or the detection point P2 provided in the terminal member 2 may be selected from the detection points P121 and P123 close to the contact portion with the holding member (terminal block 45) in the terminal member 2, for example.
- the temperature detector 5 detects the temperatures of the detection points P112, P113, P114 (see FIG. 5A) set in the internal space 40 of the housing 4 instead of on the connection member 3, the lead plate 30, or the terminal member 2.

- the temperature rise of the connection member 3 often occurs due to the contact portion of the connection member 3 with the plug blade 911 being a heat source, while the temperature rise of the terminal member 2 is In many cases, the contact portion of the member 2 with the core wire 921 is a heat source. Furthermore, the temperature rise in the internal space 40 of the housing 4 is caused by the temperature rise in the terminal member 2 or the connection member 3. Therefore, the detection points P1, P2 provided on the terminal member 2, the detection points P3, P4 provided on the connection member 3, and the detection point P5 provided on the internal space 40 of the housing 4 are subject to temperature changes.

- “can be switched from the cut-off state to the conductive state” means that the switching of the opening / closing unit 6 from the cut-off state to the conductive state is permitted, that is, switching the open / close unit 6 in the cut-off state to the conductive state. It means an allowed state. For this reason, unless it is “switchable from the cut-off state to the conductive state”, the switching unit 6 in the cut-off state is prohibited from switching to the conductive state and maintains the cut-off state.
- the switching of the opening / closing unit 6 from the cut-off state to the conductive state may be performed manually by the user, or for example, a recovery signal from the outside of the outlet 1 is received, or a recovery such as a predetermined time elapses.
- the outlet system 10 may perform automatically.
- the control unit 7 receives the detection signal from the temperature detection unit 5 to acquire the detected temperature. Then, the control unit 7 compares the threshold temperature stored in the memory or the like with the detected temperature, and determines the determination condition. When it is determined that the determination condition is satisfied, the control unit 7 outputs a drive signal to the opening / closing unit 6 and switches the opening / closing unit 6 from the conductive state to the cutoff state.
- the determination condition is that the detected temperature is not less than the threshold temperature. That is, the determination condition is satisfied if the detected temperature is equal to or higher than the threshold temperature, and the determination condition is not satisfied if the detected temperature is lower than the threshold temperature.
- the temperature detection unit 5 detects the temperature of the connection member 3 as a detection temperature, and detects the temperature of the terminal member 2 as an auxiliary detection temperature.
- the auxiliary detection condition including that the auxiliary detection temperature is equal to or higher than the auxiliary threshold temperature is satisfied, the opening / closing unit 6 switches from the conduction state to the cutoff state, and switching from the cutoff state to the conduction state is limited. That is, in this embodiment, the temperature detection unit 5 detects only the temperature of the connection member 3 among the terminal member 2 and the connection member 3 as the detection temperature, and the temperature of the terminal member 2 is different from the detection temperature.

- the temperature of the terminal member 2 auxiliary detection temperature
- the switching unit 6 is switched from the conductive state to the cut-off state, but switching from the cut-off state to the conductive state is limited. That is, when the auxiliary detection temperature satisfies the auxiliary determination condition, even if the auxiliary determination condition is not satisfied, switching of the opening / closing unit 6 from the cutoff state to the conduction state is restricted (for example, prohibited).
- the auxiliary determination condition is that the auxiliary detection temperature is equal to or higher than the auxiliary threshold temperature as in the determination condition. That is, if the auxiliary detection temperature is equal to or higher than the auxiliary threshold temperature, the auxiliary determination condition is satisfied, and if the auxiliary detection temperature is lower than the auxiliary threshold temperature, the determination condition is not satisfied.

- the display mode of the display unit 82 there are a plurality of patterns of display modes depending on the combination of the lighting states of the first indicator lamp 821 and the second indicator lamp 822 (light-off, lighting or blinking, etc.). For example, the display unit 82 displays “normal” by turning on the first indicator lamp 821 and turning off the second indicator lamp 822 in a steady state when the open / close unit 6 is in a conductive state. On the other hand, when the caution determination condition including that the temperature detected by the temperature detection unit 5 is equal to or higher than the caution temperature lower than the threshold temperature is satisfied, the display unit 82 turns on the first display lamp 821 and turns on the second display lamp 822. “Caution” is displayed by blinking. Further, when the opening / closing unit 6 is switched from the conductive state to the cut-off state, the display unit 82 displays the “warning” by turning on the first indicator lamp 821 and turning on the second indicator lamp 822.

That is, as described above, heat from the connection member 3 may be transmitted to the holding members (the inner block 44 and the outer cover 42) that hold the connection member 3, and the characteristics of the holding member are affected by the heat. The characteristics of the holding member may change (including alteration, discoloration, and deformation).

- the “predetermined change” in the present disclosure is a change when the upper limit of the allowable range is reached in the change in the characteristics of the holding member.
- the allowable range of the characteristics of the holding member is defined in a specific standard, it is preferable that the characteristics of the holding member fall within the allowable range even if the temperature rises. Therefore, by setting the temperature lower than the detection temperature when the characteristics of the holding member change to a predetermined value as the threshold temperature, the opening / closing portion 6 is set in the shut-off state before the change of the characteristics of the holding member exceeds the predetermined change. Is possible. Thereby, before the characteristic of a holding member deteriorates, the further temperature rise can be suppressed by making the opening-and-closing part 6 into a cutoff state, and the outlet 1 can be prepared for reuse.
- the outlet system 10 includes the operation member 81 that receives an operation from the user as described above, and the operation member 81 is linked to the opening / closing unit 6. Therefore, the opening / closing part 6 is switched from the cut-off state to the conductive state by the operation (recovery operation) of the operation member 81 when the determination condition is not satisfied. That is, after the opening / closing unit 6 is switched from the conductive state to the shut-off state after satisfying the determination condition, if the factor satisfying the determination condition is resolved and the restoration operation is performed in a state where the determination condition is not satisfied, the opening / closing unit 6 Switch from the interrupted state to the conductive state. Thereby, the user can manually switch the opening / closing part 6 from the cut-off state to the conductive state.
- the operation member 81 moves between the on position and the off position in conjunction with the opening / closing portion 6. That is, since whether the opening / closing unit 6 is in the conductive state or the blocking state is also indicated depending on the position of the operation member 81, the operation member 81 also functions as a state presentation unit that presents the state of the opening / closing unit 6.
- a portion of the operation member 81 that is visible only when the operation member 81 is in the off position is colored red or the like, so that the operation member 81 has an on position and an off position. It can be visually recognized from a distance.

- the caution temperature Tth1 is a temperature that is compared with the detected temperature in order to determine whether the caution determination condition is satisfied, that is, whether the notification by the notification unit 71 is performed.
- the attention temperature Tth1 is a temperature lower than the threshold temperature Tth2. If the measured temperature T1 is less than the caution temperature Tth1 (S2: No), the control unit 7 determines that the caution determination condition is not satisfied, the buzzer 83 stop processing (S3), and “normal” on the display unit 82. Display (S4) is executed, and the process returns to step S1.
- step S2 determines that the caution determination condition is satisfied, and the notification from the notification unit 71, that is, from the buzzer 83, is performed.

- the threshold temperature Tth2 is a temperature that is compared with the detected temperature in order to determine whether or not the determination condition is satisfied, that is, whether or not the opening / closing unit 6 is in the shut-off state. Further, in the present embodiment, the threshold temperature Tth2 also serves as an auxiliary threshold temperature that is compared with the auxiliary detection temperature in order to determine whether or not the auxiliary determination condition is satisfied. That is, the auxiliary threshold temperature is equal to the threshold temperature Tth2. If the measured temperature T1 is less than the threshold temperature Tth2 (S10: No), the control unit 7 determines that the determination condition and the auxiliary determination condition are not satisfied, and returns to the process S1.
- step S10 determines that the determination condition or the auxiliary determination condition is satisfied, and outputs a drive signal to the opening / closing unit 6. Then, the opening / closing part 6 is switched from the conduction state to the cutoff state (S11). Thereafter, the control unit 7 presents the state presentation unit 72, that is, outputs a warning sound from the buzzer 83 (S12), and displays a “warning” on the display unit 82 (S13).
- the control unit 7 determines whether or not the measured temperature T1 determined to be equal to or higher than the threshold temperature Tth2 is the temperature of the connection member 3. That is, if the actually measured temperature T1 at this time is the temperature of the connecting member 3 (S16: Yes), it is determined that the determination condition is satisfied in the process S10.
- the process proceeds to processing S17 that can be switched from the cutoff state to the conductive state. In this state, when the restoration operation of the operation member 81 is performed (S17: Yes), the opening / closing part 6 is switched from the cut-off state to the conductive state (S18), and the process proceeds to step S9.
- the control unit 7 immediately switches the opening / closing unit 6 from the conduction state to the cutoff state. (S11).
- the control unit 7 determines that the determination condition and the auxiliary determination condition are not satisfied, and returns to the process S1. Thereby, the opening / closing part 6 maintains a conductive state, and the outlet 1 becomes reusable.
- process S16 when it is determined in process S16 that the measured temperature T1 determined to be equal to or higher than the threshold temperature Tth2 is not the temperature of the connecting member 3 (S16: No), it is determined in process S10 that the auxiliary determination condition is satisfied. It will be. In this case, the control unit 7 proceeds to a process S19 in which the opening / closing unit 6 cannot be switched from the cutoff state to the conductive state. In this state, when the restoration operation of the operation member 81 is performed (S19: Yes), the control unit 7 forcibly maintains the open / close unit 6 in the shut-off state by the drive signal (S11).
- any of the processing S17 and the processing S19 if the restoration operation is not performed (No in S17 or S19), the control unit 7 proceeds to the processing S14.
- the opening / closing part 6 when the determination condition is not satisfied, the opening / closing part 6 can be switched from the cut-off state to the conduction state. That is, in the outlet system 10, if the determination condition is satisfied, even if the opening / closing unit 6 is once in a shut-off state, the factor that satisfies the determination condition is eliminated. It is possible to return the part 6 to the conductive state. Therefore, according to the outlet system 10, the outlet system 10 (outlet 1) can be recovered without replacing the outlet system 10 (outlet 1) by restoring the opening and closing unit 6 even if the opening and closing unit 6 is once cut off.

That is, in the present embodiment, all the components of the outlet system 10 are integrated into one outlet 1, and the outlet system 10 and the outlet 1 are the same.
(1)概要
本実施形態に係るコンセントシステム10は、図1Aに示すように、コンセント1を備えている。コンセント1(Outlet)は、端子部材2と、接続部材3と、筐体4(図2A参照)と、を有している。本実施形態では、コンセントシステム10における筐体4以外の構成要素(端子部材2及び接続部材3等)は全て、筐体4に収容又は保持されている。つまり、本実施形態では、コンセントシステム10の構成要素は全て1つのコンセント1に集約されており、コンセントシステム10とコンセント1とは同一である。 (Embodiment 1)
(1) Outline The
本実施形態に係るコンセント1(コンセントシステム10)は、例えば、電気機器のプラグ91(図5A参照)が接続されて電気機器への電力供給を行う配線器具、つまりアウトレット(Outlet)である。コンセント1は、例えば、戸建住宅若しくは集合住宅等の住宅施設、又は事務所、店舗、学校若しくは介護施設等の非住宅施設等に設置される。コンセント1は、例えば、施設(建物)の壁面、天井面及び床面等の造営面100(図2A参照)に取り付けられる。
The outlet 1 (outlet system 10) according to the present embodiment is, for example, a wiring device that is connected to a plug 91 (see FIG. 5A) of an electrical device and supplies power to the electrical device, that is, an outlet. The outlet 1 is installed, for example, in a residential facility such as a detached house or an apartment house, or a non-residential facility such as an office, a store, a school, or a nursing facility. The outlet 1 is attached to a construction surface 100 (see FIG. 2A) such as a wall surface, a ceiling surface, and a floor surface of a facility (building), for example.
本実施形態に係るコンセントシステム10は、図1A及び図1Bに示すように、端子部材2、接続部材3及び筐体4に加えて、温度検出部5、開閉部6及び伝熱構造50を更に備えている。端子部材2は、給電線92(図5B参照)が接続される部材である。接続部材3は、プラグ91が接続される部材である。筐体4は、端子部材2及び接続部材3を収容する。
As shown in FIGS. 1A and 1B, the outlet system 10 according to the present embodiment further includes a temperature detection unit 5, an opening / closing unit 6, and a heat transfer structure 50 in addition to the terminal member 2, the connection member 3, and the housing 4. I have. The terminal member 2 is a member to which a feeder line 92 (see FIG. 5B) is connected. The connection member 3 is a member to which the plug 91 is connected. The housing 4 accommodates the terminal member 2 and the connection member 3.
温度検出部5は、1つの温度センサ51を含んでいる。温度検出部5は、複数の第1検出点と、複数の第2検出点と、の少なくとも一方を含む検出点群P100の温度を、検出温度として1つの温度センサ51にて検出する。複数の第1検出点は、互いに電気的に絶縁された複数の検出点である。複数の第2検出点は、端子部材2、接続部材3、及び筐体4の内部空間40(図1B参照)のうち互いに異なる部位に設けられた複数の検出点である。詳しくは後述するが、一例として、図1Bにおける検出点P1及び検出点P2の組み合わせ(又は検出点P3及び検出点P4の組み合わせ)が、複数の第1検出点となる。一方、図1Bにおける検出点P1、検出点P3及び検出点P5の組み合わせ(又は検出点P2、検出点P4及び検出点P5の組み合わせ)が、複数の第2検出点となる。
The temperature detection unit 5 includes one temperature sensor 51. The temperature detection unit 5 detects the temperature of the detection point group P100 including at least one of the plurality of first detection points and the plurality of second detection points with one temperature sensor 51 as the detection temperature. The plurality of first detection points are a plurality of detection points that are electrically insulated from each other. The plurality of second detection points are a plurality of detection points provided at different portions of the terminal member 2, the connection member 3, and the internal space 40 (see FIG. 1B) of the housing 4. As will be described in detail later, as an example, a combination of the detection point P1 and the detection point P2 in FIG. 1B (or a combination of the detection point P3 and the detection point P4) becomes a plurality of first detection points. On the other hand, the combination of the detection point P1, the detection point P3, and the detection point P5 in FIG. 1B (or the combination of the detection point P2, the detection point P4, and the detection point P5) becomes a plurality of second detection points.
ここで、1つの温度センサ51での温度の検出対象となる検出点群P100は、複数の第1検出点と、複数の第2検出点と、の少なくとも一方を含んでいればよい。つまり、検出点群P100は、複数の第1検出点及び複数の第2検出点のうち、複数の第1検出点のみを含んでいてもよいし、複数の第2検出点のみを含んでいてもよいし、複数の第1検出点及び複数の第2検出点の両方を含んでいてもよい。検出点群P100が複数の第1検出点及び複数の第2検出点の両方を含む場合において、一部の第1検出点と一部の第2検出点とは重複していてもよい。つまり、図1Bの例において検出点P1は、検出点P2との組み合わせでは第1検出点となり、検出点P3及び検出点P5との組み合わせでは第2検出点となる。このように、一部の第1検出点は、一部の第2検出点と同一の検出点(例えば検出点P1)であってもよい。
Here, the detection point group P100 that is a temperature detection target of one temperature sensor 51 only needs to include at least one of a plurality of first detection points and a plurality of second detection points. That is, the detection point group P100 may include only a plurality of first detection points among a plurality of first detection points and a plurality of second detection points, or may include only a plurality of second detection points. Alternatively, both the plurality of first detection points and the plurality of second detection points may be included. When the detection point group P100 includes both a plurality of first detection points and a plurality of second detection points, some of the first detection points and some of the second detection points may overlap. That is, in the example of FIG. 1B, the detection point P1 becomes the first detection point when combined with the detection point P2, and becomes the second detection point when combined with the detection point P3 and the detection point P5. In this way, some of the first detection points may be the same detection points (for example, detection point P1) as some of the second detection points.
開閉部6は、端子部材2と接続部材3との間に電気的に接続されている。開閉部6は、判定条件を満たしたときに、導通状態から遮断状態に切り替わる。判定条件は、検出温度が閾値温度以上であることを含んでいる。伝熱構造50は、検出点群P100と1つの温度センサ51とを熱的に結合する。本開示でいう「熱的に結合」とは、熱伝導、放射若しくは対流、又はこれらの組み合わせによって、2点間で熱(熱エネルギー)が移動するように2点間を結合することを意味する。つまり、伝熱構造50にて熱的に結合された検出点群P100と1つの温度センサ51との間では、熱の移動が可能である。
The opening / closing part 6 is electrically connected between the terminal member 2 and the connecting member 3. The opening / closing part 6 switches from the conduction state to the cutoff state when the determination condition is satisfied. The determination condition includes that the detected temperature is equal to or higher than the threshold temperature. The heat transfer structure 50 thermally couples the detection point group P100 and one temperature sensor 51. The term “thermally coupled” in the present disclosure means that two points are coupled by heat conduction, radiation, convection, or a combination thereof so that heat (thermal energy) is transferred between the two points. . That is, heat can be transferred between the detection point group P100 thermally coupled by the heat transfer structure 50 and one temperature sensor 51.
上記構成によれば、コンセントシステム10は、温度検出部5での検出温度が閾値温度以上になって判定条件を満たすと、開閉部6が導通状態から遮断状態に切り替わることで、端子部材2と接続部材3との間が電気的に遮断される。そのため、コンセントシステム10は、例えば、端子部材2と給電線92との接触不良、又は接続部材3とプラグ91との接触不良等により、検出温度が上昇することがあれば、自動で、接続部材3を端子部材2から電気的に切り離すことが可能である。これにより、例えば、接続部材3に電気機器のプラグ91が接続されたままの状態にあっても、電気機器への電力供給が停止し、更なる発熱を抑制することが可能である。
According to the above configuration, when the temperature detected by the temperature detection unit 5 is equal to or higher than the threshold temperature and satisfies the determination condition, the outlet system 10 switches the switching unit 6 from the conductive state to the cutoff state, thereby The connection member 3 is electrically disconnected. Therefore, the outlet system 10 automatically connects the connecting member if the detected temperature rises due to, for example, poor contact between the terminal member 2 and the power supply line 92 or poor contact between the connecting member 3 and the plug 91. 3 can be electrically disconnected from the terminal member 2. Thereby, for example, even when the plug 91 of the electrical device is still connected to the connection member 3, the power supply to the electrical device is stopped, and further heat generation can be suppressed.
しかも、上記コンセントシステム10では、温度検出部5は、1つの温度センサ51にて、複数の第1検出点と、複数の第2検出点と、の少なくとも一方を含む検出点群P100の温度を、検出温度として検出する。すなわち、コンセントシステム10においては、互いに電気的に絶縁された複数の第1検出点、及び互いに異なる部位に設けられた複数の第2検出点、の少なくとも一方の温度を、1つの温度センサ51が検出する。したがって、1つの温度センサ51は、例えば、複数の第1検出点の温度の検出に共用されることになる。または、1つの温度センサ51は、例えば、複数の第2検出点の温度の検出に共用されることになる。そのため、複数の第1検出点の各々に個別の温度センサを設ける場合、又は複数の第2検出点の各々に個別の温度センサを設ける場合に比べて、必要な温度センサの個数を少なく抑えることが可能である。結果的に、上記コンセントシステム10によれば、検出点の数に対して必要な温度センサの個数を少なく抑えることができ、部品点数の増加を抑えることができる。
Moreover, in the outlet system 10, the temperature detection unit 5 uses one temperature sensor 51 to determine the temperature of the detection point group P100 including at least one of a plurality of first detection points and a plurality of second detection points. Detect as detection temperature. That is, in the outlet system 10, one temperature sensor 51 determines the temperature of at least one of a plurality of first detection points that are electrically insulated from each other and a plurality of second detection points that are provided at different sites. To detect. Accordingly, one temperature sensor 51 is commonly used for detecting the temperature at a plurality of first detection points, for example. Alternatively, one temperature sensor 51 is commonly used for detecting temperatures at a plurality of second detection points, for example. Therefore, the number of necessary temperature sensors can be reduced as compared with the case where individual temperature sensors are provided at each of the plurality of first detection points or when individual temperature sensors are provided at each of the plurality of second detection points. Is possible. As a result, according to the outlet system 10, the number of temperature sensors necessary for the number of detection points can be reduced, and an increase in the number of parts can be suppressed.

以下では、造営面100である建物の内壁面にコンセント1が取り付けられた状態での、水平面に対して垂直な(直交する)方向を「上下方向」とし、コンセント1を正面から見て下方(鉛直方向)を「下方」として説明する。また、上下方向と直交し、かつ造営面100に平行な方向を「左右方向」とし、コンセント1を正面から見て右方を「右方」、左方を「左方」として説明する。さらに、上下方向と左右方向との両方に直交する方向、つまり造営面100に直交する方向を「前後方向」とし、造営面100の裏側(壁裏側)を「後方」として説明する。ただし、これらの方向はコンセントシステム10の使用方向を限定する趣旨ではない。例えば、コンセント1が壁面ではなく床面に取り付けられる場合には、「前後方向」は水平面に対して垂直な方向となり、「上下方向」及び「左右方向」は水平面に平行な方向となる。また、コンセント1が壁面に取り付けられる場合でも、「上下方向」が水平面に平行な方向となる向き(つまり横向き)で、コンセント1が壁面に取り付けられることにより、「左右方向」は水平面に垂直な方向となる。
In the following, the direction perpendicular (orthogonal) to the horizontal plane in a state where the outlet 1 is attached to the inner wall surface of the building which is the construction surface 100 is referred to as “vertical direction”, and the outlet 1 is viewed downward from the front ( (Vertical direction) will be described as “downward”. In addition, a description will be made assuming that a direction orthogonal to the vertical direction and parallel to the construction surface 100 is a “left-right direction”, a right side is “right” and a left side is “left” when the outlet 1 is viewed from the front. Furthermore, the direction orthogonal to both the up-down direction and the left-right direction, that is, the direction orthogonal to the construction surface 100 will be referred to as “front-rear direction”, and the back side (wall back side) of the construction surface 100 will be described as “rear”. However, these directions are not intended to limit the usage direction of the outlet system 10. For example, when the outlet 1 is attached to the floor instead of the wall surface, the “front-rear direction” is a direction perpendicular to the horizontal plane, and the “vertical direction” and the “left-right direction” are directions parallel to the horizontal plane. Further, even when the outlet 1 is attached to the wall surface, the “left-right direction” is perpendicular to the horizontal plane when the outlet 1 is attached to the wall surface in the direction in which the “vertical direction” is parallel to the horizontal plane (that is, the horizontal direction). Direction.

In the present embodiment, the outlet system 10 is exemplified by a two-port type outlet 1 to which two plugs 91 can be connected simultaneously. That is, the outlet 1 has two connection ports 11 so as to correspond to the two plugs 91. Each of the two connection ports 11 is configured to be able to connect one plug 91, and is arranged side by side along the vertical direction (vertical direction) on the front surface of the housing 4. Of the two connection ports 11, one (upper) connection port 11 is an outlet with a two-pole grounding electrode for AC 100V, and the other (lower) connection port 11 has no grounding electrode for AC 100V. This is a two-pole outlet.
本実施形態では、2極のプラグ91に対応するように、コンセント1は、互いに異極性となる一対の端子部材2を備えている。つまり、一対の端子部材2のうち一方の端子部材2にはL極(HOT)側の給電線92が接続され、他方の端子部材2にはN極(COLD)側の給電線92が接続される。同様に、コンセント1は、各接続口11につき互いに異極性となる一対の接続部材3を備えており、計二対(4個)の接続部材3を備えている。ここで、互いに同極性である2個の接続部材3は、リード板30(図3参照)にて連結されている。さらに、互いに同極性である接続部材3と端子部材2とは、開閉部6を介して電気的に接続されている。
In the present embodiment, the outlet 1 includes a pair of terminal members 2 having different polarities so as to correspond to the two-pole plug 91. That is, the L pole (HOT) side power supply line 92 is connected to one terminal member 2 of the pair of terminal members 2, and the N pole (COLD) side power supply line 92 is connected to the other terminal member 2. The Similarly, the outlet 1 includes a pair of connection members 3 having different polarities for each connection port 11, and includes a total of two pairs (four) of connection members 3. Here, the two connection members 3 having the same polarity are connected by a lead plate 30 (see FIG. 3). Further, the connection member 3 and the terminal member 2 having the same polarity are electrically connected via the opening / closing part 6.
コンセント1は、筐体4と、筐体4に収容又は保持される端子部材2及び接続部材3等の内部部品と、を備えている。筐体4は、図3に示すように、外ボディ41と、外カバー42と、内カバー43と、内ブロック44と、端子ブロック45と、を有している。これら外ボディ41、外カバー42、内カバー43、内ブロック44及び端子ブロック45が組み合わされることにより、筐体4が構成されている。筐体4は、電気絶縁性を有する合成樹脂製である。
The outlet 1 includes a housing 4 and internal components such as a terminal member 2 and a connection member 3 that are accommodated or held in the housing 4. As shown in FIG. 3, the housing 4 includes an outer body 41, an outer cover 42, an inner cover 43, an inner block 44, and a terminal block 45. The outer body 41, the outer cover 42, the inner cover 43, the inner block 44 and the terminal block 45 are combined to form the housing 4. The housing 4 is made of a synthetic resin having electrical insulation.
外ボディ41は、前面が開口された箱状に形成されている。外ボディ41の開口面(前面)は、上下方向の寸法が左右方向の寸法よりも長い長方形状である。内ブロック44は、接続部材3を保持した状態で、他の内部部品(端子部材2及び開閉部6等)と共に外ボディ41に収容される。外ボディ41の前面には内カバー43が取り付けられる。これにより、外ボディ41と内カバー43との間には、内ブロック44に保持された状態の接続部材3を含む内部部品が収容されることになる。外カバー42は、内カバー43の前面に取り付けられる。これにより、内ブロック44と外カバー42との間に接続部材3が収容される。ここで、内カバー43のうち、内ブロック44に対応する部位には、前後方向に貫通する開口窓431が形成されている。そのため、接続部材3を保持した内ブロック44の前面は外カバー42で覆われることになり、外カバー42を外した状態では、内ブロック44の前面は開口窓431を通して前方に露出する。端子ブロック45は、端子部材2を保持した状態で、他の内部部品と共に外ボディ41に収容される。
The outer body 41 is formed in a box shape with an open front surface. The opening surface (front surface) of the outer body 41 has a rectangular shape whose vertical dimension is longer than the horizontal dimension. The inner block 44 is accommodated in the outer body 41 together with other internal components (the terminal member 2 and the opening / closing part 6 and the like) while holding the connection member 3. An inner cover 43 is attached to the front surface of the outer body 41. As a result, the internal parts including the connecting member 3 held by the inner block 44 are accommodated between the outer body 41 and the inner cover 43. The outer cover 42 is attached to the front surface of the inner cover 43. Thereby, the connection member 3 is accommodated between the inner block 44 and the outer cover 42. Here, an opening window 431 that penetrates in the front-rear direction is formed in a portion of the inner cover 43 corresponding to the inner block 44. Therefore, the front surface of the inner block 44 holding the connection member 3 is covered with the outer cover 42, and when the outer cover 42 is removed, the front surface of the inner block 44 is exposed forward through the opening window 431. The terminal block 45 is accommodated in the outer body 41 together with other internal components while holding the terminal member 2.
つまり、内ブロック44及び外カバー42は、接続部材3を保持する保持部材を構成する。端子ブロック45は、端子部材2を保持する保持部材を構成する。言い換えれば、コンセントシステム10は、端子部材2及び接続部材3の少なくとも一方を保持する保持部材を更に備えている。
That is, the inner block 44 and the outer cover 42 constitute a holding member that holds the connection member 3. The terminal block 45 constitutes a holding member that holds the terminal member 2. In other words, the outlet system 10 further includes a holding member that holds at least one of the terminal member 2 and the connecting member 3.
本実施形態では、外カバー42は更に複数の部材(例えば3つの部材)に分割可能に構成されているが、外カバー42は一体(一部材)であってもよい。ここで、外カバー42のうち内ブロック44を覆う部位、及び内ブロック44は、例えば、ユリア樹脂製である。
In the present embodiment, the outer cover 42 is configured to be further divided into a plurality of members (for example, three members), but the outer cover 42 may be integrated (one member). Here, the part which covers the inner block 44 among the outer covers 42, and the inner block 44 are made of urea resin, for example.
外カバー42のうち内ブロック44を覆う部位には、上述した2個の接続口11が形成されている。2個の接続口11のうち一方(上方)の接続口11は、プラグ91の一対の栓刃911(図5A参照)が差し込まれる一対の挿入孔111を有している。2個の接続口11のうち他方(下方)の接続口11は、一対の挿入孔111に加えて、接地極付きプラグの接地ピンが差し込まれる接地挿入孔112、及びアース蓋113を有している。筐体4の内部において、各挿入孔111に対応する位置には接続部材3が配置され、接地挿入孔112に対応する位置には第1接地部材114が配置され、アース蓋113に対応する位置には第2接地部材115が配置される。第1接地部材114は、接地極付きプラグの接地ピンが接続されるばね部材である。第2接地部材115は、電気機器の接地線が接続されるねじ式端子である。接地線は、アース蓋113が開いた状態で第2接地部材115への着脱が可能になる。
The two connection ports 11 described above are formed in a portion of the outer cover 42 that covers the inner block 44. One (upper) connection port 11 of the two connection ports 11 has a pair of insertion holes 111 into which a pair of plug blades 911 (see FIG. 5A) of the plug 91 are inserted. The other (lower) connection port 11 of the two connection ports 11 includes a ground insertion hole 112 into which a ground pin of a plug with a ground electrode is inserted and a ground lid 113 in addition to the pair of insertion holes 111.

The second grounding member 115 is disposed at the center. The first ground member 114 is a spring member to which a ground pin of a plug with a ground electrode is connected. The second ground member 115 is a screw-type terminal to which a ground wire of an electric device is connected. The ground wire can be attached to and detached from the second ground member 115 with the ground cover 113 opened.
また、外ボディ41と内カバー43との間の空間であって内ブロック44の左方には、開閉部6及び基板85が収容されている。基板85は、開閉部6の上方に配置されている。基板85には、表示部82を構成する第1表示灯821及び第2表示灯822、並びにスイッチ84が実装されている。一例として、第1表示灯821及び第2表示灯822は、互いに発光色の異なるLED(Light Emitting Diode)であって、スイッチ84は、押ボタンスイッチである。このように、開閉部6、表示部82及びスイッチ84は、筐体4(外ボディ41及び内カバー43)内に収容されている。ただし、表示部82の光が筐体4の前方から視認可能となり、かつ筐体4の前方からスイッチ84の押操作が可能となるように、内カバー43には透光部432及びカンチレバー433が形成されている。つまり、表示部82の光は透光部432を通して筐体4の前方から視認可能であって、スイッチ84はカンチレバー433を介して筐体4の前方から押操作可能である。図2A及び図2Bでは、便宜上、筐体4の前面における表示部82(第1表示灯821及び第2表示灯822)及びスイッチ84に対応する各位置に、表示部82及びスイッチ84の符号を付している。
Further, the opening / closing part 6 and the substrate 85 are accommodated in the space between the outer body 41 and the inner cover 43 and to the left of the inner block 44. The substrate 85 is disposed above the opening / closing part 6. A first indicator lamp 821 and a second indicator lamp 822 that constitute the display unit 82 and a switch 84 are mounted on the substrate 85. As an example, the first indicator lamp 821 and the second indicator lamp 822 are LEDs (Light Emitting Diode) having different emission colors, and the switch 84 is a pushbutton switch. As described above, the opening / closing unit 6, the display unit 82, and the switch 84 are accommodated in the housing 4 (the outer body 41 and the inner cover 43). However, the inner cover 43 has a translucent portion 432 and a cantilever 433 so that the light of the display portion 82 can be viewed from the front of the housing 4 and the switch 84 can be pushed from the front of the housing 4. Is formed. That is, the light of the display unit 82 can be visually recognized from the front of the housing 4 through the light transmitting portion 432, and the switch 84 can be pushed from the front of the housing 4 via the cantilever 433. In FIG. 2A and FIG. 2B, for convenience, reference numerals of the display unit 82 and the switch 84 are indicated at positions corresponding to the display unit 82 (first display lamp 821 and second display lamp 822) and the switch 84 on the front surface of the housing 4. It is attached.
制御部7は、筐体4に収容されており、例えば、内ブロック44の後方に配置された制御基板に実装されている。ブザー83についても同様に、筐体4に収容されており、例えば、制御基板に実装されている。制御部7は、開閉部6、表示部82、ブザー83、スイッチ84及び温度検出部5に電気的に接続されている。制御部7は、少なくとも開閉部6、表示部82及びブザー83の制御を行う。
The control unit 7 is accommodated in the housing 4 and mounted on, for example, a control board disposed behind the inner block 44. Similarly, the buzzer 83 is accommodated in the housing 4 and mounted on, for example, a control board. The control unit 7 is electrically connected to the opening / closing unit 6, the display unit 82, the buzzer 83, the switch 84, and the temperature detection unit 5. The control unit 7 controls at least the opening / closing unit 6, the display unit 82, and the buzzer 83.
制御部7は、例えば、マイクロコンピュータを主構成として備えている。マイクロコンピュータは、マイクロコンピュータのメモリに記録されているプログラムをCPU(Central Processing Unit)で実行することにより、制御部7としての機能を実現する。プログラムは、予めマイコンのメモリに記録されていてもよいし、メモリカードのような非一時的記録媒体に記録されて提供されたり、電気通信回線を通して提供されたりしてもよい。言い換えれば、上記プログラムは、マイクロコンピュータを、制御部7として機能させるためのプログラムである。
The control unit 7 includes, for example, a microcomputer as a main configuration. The microcomputer realizes the function as the control unit 7 by executing a program recorded in the memory of the microcomputer by a CPU (Central Processing Unit). The program may be recorded in advance in the memory of the microcomputer, may be provided by being recorded in a non-transitory recording medium such as a memory card, or may be provided through an electric communication line. In other words, the program is a program for causing the microcomputer to function as the control unit 7.
また、制御部7は、報知部71としての機能、及び状態提示部72としての機能を有している。報知部71は、温度検出部5での検出温度が閾値温度より低い注意温度以上であることを含む注意判定条件を満たしたときに報知を行う。本実施形態では一例として、報知部71での報知は、ブザー83からの注意音の出力、及び表示部82での注意表示により実現される。つまり、制御部7は、ブザー83及び表示部82を制御することにより報知部71での報知を実現する。状態提示部72は、開閉部6が導通状態にあるか遮断状態にあるかを提示する。本実施形態では一例として、状態提示部72での提示は、ブザー83からの警告音の出力、及び表示部82での警告表示により実現される。つまり、制御部7は、ブザー83及び表示部82を制御することにより状態提示部72での提示を実現する。制御部7(報知部71及び状態提示部72を含む)について詳しくは「(2.3)動作」の欄で説明する。
Further, the control unit 7 has a function as the notification unit 71 and a function as the state presentation unit 72. The alerting | reporting part 71 alert | reports, when satisfy | filling the caution determination conditions including the temperature detected by the temperature detection part 5 being more than the caution temperature lower than threshold value temperature. In this embodiment, as an example, the notification by the notification unit 71 is realized by the output of a caution sound from the buzzer 83 and the caution display on the display unit 82. That is, the control unit 7 realizes notification by the notification unit 71 by controlling the buzzer 83 and the display unit 82. The state presentation unit 72 presents whether the opening / closing unit 6 is in a conductive state or a cutoff state. In the present embodiment, as an example, the presentation by the state presentation unit 72 is realized by outputting a warning sound from the buzzer 83 and displaying a warning on the display unit 82. That is, the control unit 7 realizes the presentation by the state presentation unit 72 by controlling the buzzer 83 and the display unit 82. The control unit 7 (including the notification unit 71 and the state presentation unit 72) will be described in detail in the section “(2.3) Operation”.
スイッチ84は、ブザー83の音出力を停止させる際に操作される。つまり、ブザー83が注意音又は警告音を出力している状態でスイッチ84が押操作されると、ブザー83を停止させるように、制御部7がブザー83を制御する。また、スイッチ84は、テストスイッチとしても兼用されており、開閉部6を強制的に導通状態から遮断状態に切り替える場合にも使用される。
The switch 84 is operated when the sound output of the buzzer 83 is stopped. That is, when the switch 84 is pressed while the buzzer 83 outputs a caution sound or a warning sound, the control unit 7 controls the buzzer 83 so that the buzzer 83 is stopped. The switch 84 is also used as a test switch, and is also used when the opening / closing part 6 is forcibly switched from a conductive state to a cut-off state.
開閉部6は、端子部材2と接続部材3との間に電気的に接続されている。開閉部6は、導通状態及び遮断状態の2つの状態が切り替わる装置である。すなわち、開閉部6が導通状態にあれば、端子部材2と接続部材3との間は開閉部6を介して導通し、開閉部6が遮断状態にあれば、端子部材2と接続部材3との間は開閉部6にて電気的に遮断(絶縁)される。本実施形態では、上述したように、コンセント1は互いに異極性となる一対の端子部材2を備えており、開閉部6は、一対の端子部材2の両方に対して電気的に接続されている。そのため、開閉部6が遮断状態にあれば、二対(4個)の接続部材3は、全て端子部材2から電気的に切り離されることになる。
The opening / closing part 6 is electrically connected between the terminal member 2 and the connecting member 3. The opening / closing unit 6 is a device that switches between two states, a conduction state and a cutoff state. That is, if the opening / closing part 6 is in a conducting state, the terminal member 2 and the connecting member 3 are electrically connected via the opening / closing part 6, and if the opening / closing part 6 is in a shut-off state, the terminal member 2 and the connecting member 3 Is electrically disconnected (insulated) by the opening / closing part 6. In the present embodiment, as described above, the outlet 1 includes the pair of terminal members 2 having different polarities, and the opening / closing part 6 is electrically connected to both of the pair of terminal members 2. . Therefore, if the opening / closing part 6 is in the cut-off state, the two pairs (four pieces) of the connection members 3 are all electrically disconnected from the terminal member 2.
具体的には、開閉部6は、互いに異極性となる一対の接点装置と、電磁釈放装置と、を有している。一対の接点装置の各々は、固定接点及び可動接点を有している。可動接点は、固定接点に接触する閉位置と、固定接点から離れた開位置との間で移動する。固定接点には端子部材2が電気的に接続され、可動接点には接続部材3が電気的に接続される。より詳細には、可動接点は可動接触子に設けられており、可動接触子が編組線にてリード板30に接続されることにより、可動接点と接続部材3とが電気的に接続される。
Specifically, the opening / closing part 6 has a pair of contact devices having different polarities and an electromagnetic release device. Each of the pair of contact devices has a fixed contact and a movable contact. The movable contact moves between a closed position in contact with the fixed contact and an open position away from the fixed contact. The terminal member 2 is electrically connected to the fixed contact, and the connection member 3 is electrically connected to the movable contact. More specifically, the movable contact is provided on the movable contact, and the movable contact and the connecting member 3 are electrically connected by connecting the movable contact to the lead plate 30 with a braided wire.
このような構成の開閉部6は、定常時には、可動接点が閉位置に位置することで、端子部材2と接続部材3との間を導通させる導通状態にある。一方、開閉部6は、制御部7からの駆動信号を受けると、電磁釈放装置を作動させて可動接触子を駆動し、可動接点を開位置に移動させることで、端子部材2と接続部材3との間を電気的に遮断する遮断状態に切り替わる。このように、開閉部6は、制御部7からの駆動信号により、導通状態から遮断状態に切り替わる。
The opening / closing section 6 having such a configuration is in a conductive state in which the movable contact is located at the closed position so that the terminal member 2 and the connection member 3 are electrically connected. On the other hand, when the opening / closing unit 6 receives a drive signal from the control unit 7, the electromagnetic release device is operated to drive the movable contact and move the movable contact to the open position, whereby the terminal member 2 and the connection member 3 are moved. It switches to the interruption | blocking state which interrupts | blocks electrically between. As described above, the opening / closing unit 6 is switched from the conductive state to the cut-off state by the drive signal from the control unit 7.
また、開閉部6には、操作部材81が機械的に結合されている。操作部材81は、回転軸を中心に回転可能なレバー式ハンドルである。ここで、筐体4の前方から操作部材81の操作が可能となるように、内カバー43及び外カバー42にはそれぞれ第1操作孔434及び第2操作孔421が形成されている。つまり、操作部材81は、第1操作孔434及び第2操作孔421を通して筐体4の前方に露出し、筐体4の前方から操作可能となる。
Further, an operating member 81 is mechanically coupled to the opening / closing part 6. The operation member 81 is a lever-type handle that can rotate around a rotation axis. Here, a first operation hole 434 and a second operation hole 421 are formed in the inner cover 43 and the outer cover 42 so that the operation member 81 can be operated from the front of the housing 4. That is, the operation member 81 is exposed to the front of the housing 4 through the first operation hole 434 and the second operation hole 421 and can be operated from the front of the housing 4.
操作部材81は、開閉部6に連動して回転し、オン位置(図2A参照)、オフ位置(図2B参照)との間で移動する。オン位置は開閉部6の導通状態に対応する位置であって、オフ位置は開閉部6の遮断状態に対応する位置である。つまり、開閉部6が導通状態にあれば、図2Aに示すように、操作部材81がオン位置に位置する。操作部材81がオン位置にあるとき、操作部材81の前面は筐体4の前面と略面一になる。一方、開閉部6が導通状態から遮断状態に切り替わると、操作部材81が回転して操作部材81の先端部が前方(手前側)に移動し、図2Bに示すように、操作部材81がオフ位置に移動する。操作部材81がオフ位置にあるとき、操作部材81は筐体4の前面から前方に突出する。
The operating member 81 rotates in conjunction with the opening / closing part 6 and moves between an on position (see FIG. 2A) and an off position (see FIG. 2B). The on position is a position corresponding to the conduction state of the opening / closing part 6, and the off position is a position corresponding to the blocking state of the opening / closing part 6. That is, if the opening / closing part 6 is in a conductive state, the operation member 81 is located at the on position as shown in FIG. 2A. When the operation member 81 is in the on position, the front surface of the operation member 81 is substantially flush with the front surface of the housing 4. On the other hand, when the opening / closing part 6 is switched from the conductive state to the cut-off state, the operation member 81 rotates and the front end of the operation member 81 moves forward (front side), and the operation member 81 is turned off as shown in FIG. 2B. Move to position. When the operation member 81 is in the off position, the operation member 81 protrudes forward from the front surface of the housing 4.
このように、操作部材81と開閉部6とは連動しているので、開閉部6が制御部7からの駆動信号を受けて開閉部6が導通状態から遮断状態に切り替わると、操作部材81はオン位置からオフ位置に移動する。反対に、操作部材81がオフ位置からオン位置に移動すると、開閉部6が遮断状態から導通状態に切り替わる。そのため、オフ位置にある操作部材81をユーザが操作してオン位置に移動させることで、遮断状態にある開閉部6を導通状態に切り替えることができる。以下では、操作部材81をオフ位置からオン位置に移動させる操作を、「復旧操作」という。復旧操作について詳しくは「(2.3)動作」の欄で説明する。
Thus, since the operation member 81 and the opening / closing part 6 are interlocked, when the opening / closing part 6 receives the drive signal from the control part 7 and the opening / closing part 6 is switched from the conductive state to the cutoff state, the operation member 81 is Move from the on position to the off position. On the contrary, when the operation member 81 moves from the off position to the on position, the opening / closing part 6 is switched from the shut-off state to the conductive state. Therefore, when the user operates the operating member 81 in the off position and moves it to the on position, the open / close section 6 in the shut-off state can be switched to the conductive state. Hereinafter, the operation of moving the operation member 81 from the off position to the on position is referred to as “recovery operation”. Details of the restoration operation will be described in the section “(2.3) Operation”.
また、本実施形態では、開閉部6は、制御部7からの駆動信号を受けた場合のみならず、操作部材81をオン位置からオフ位置に移動させた場合にも、導通状態から遮断状態に切り替わる。そのため、開閉部6の導通状態と遮断状態とは、操作部材81の操作によりユーザが手動で切り替えることが可能である。言い換えれば、開閉部6は、操作部材81の操作に応じてオンオフするスイッチ装置として機能する。
Further, in the present embodiment, the opening / closing unit 6 changes from the conduction state to the cutoff state not only when the drive signal is received from the control unit 7 but also when the operation member 81 is moved from the on position to the off position. Switch. Therefore, the user can manually switch between the conduction state and the cutoff state of the opening / closing unit 6 by operating the operation member 81. In other words, the opening / closing part 6 functions as a switch device that is turned on / off in accordance with the operation of the operation member 81.
次に、接続部材3及び端子部材2の構成について、図4A~図5Bを参照して説明する。
Next, the configuration of the connection member 3 and the terminal member 2 will be described with reference to FIGS. 4A to 5B.

Each connection member 3 is made of a metal having conductivity and elasticity, such as copper or a copper alloy. Each connection member 3 has a pair of blade receiving pieces 31 that face each other in the left-right direction. Each connecting member 3 is electrically connected to the plug blade 911 and mechanically holds the plug blade 911 with the plug blade 911 sandwiched between the pair of blade receiving pieces 31.
一対の端子部材2は、図4B及び図5Bに示すように、端子ブロック45に保持されている。ここで、一対の端子部材2は、端子ブロック45の後面に形成された一対の端子孔121にそれぞれ対応する位置に配置されている。各端子部材2は、給電線92の心線921が差し込まれることで給電線92が接続される、差込式の速結端子である。具体的には、各端子部材2は、図5Bに示すように、端子板21及び鎖錠ばね22を有している。端子板21は、導電性を有する金属、例えば、銅又は銅合金等からなる。鎖錠ばね22は、弾性を有する金属、例えば、ステンレス等からなる。各端子部材2は、筐体4の後面に開口した端子孔121に給電線92が挿入されると、端子板21と鎖錠ばね22との間に給電線92の心線を挟んだ状態で、給電線92と電気的に接続され、かつ栓刃911を機械的に保持する。
The pair of terminal members 2 are held by the terminal block 45 as shown in FIGS. 4B and 5B. Here, the pair of terminal members 2 are arranged at positions corresponding to the pair of terminal holes 121 formed on the rear surface of the terminal block 45. Each terminal member 2 is a plug-in type quick connection terminal to which the feeder line 92 is connected when the core wire 921 of the feeder line 92 is inserted. Specifically, each terminal member 2 has a terminal plate 21 and a lock spring 22 as shown in FIG. 5B. The terminal board 21 is made of a conductive metal, such as copper or a copper alloy. The lock spring 22 is made of an elastic metal such as stainless steel. In each terminal member 2, when the feeder line 92 is inserted into the terminal hole 121 opened on the rear surface of the housing 4, the core wire of the feeder line 92 is sandwiched between the terminal plate 21 and the lock spring 22. , Electrically connected to the feeder line 92 and mechanically holding the plug blade 911.
さらに、端子ブロック45には、アース線を接続するための接地端子116(図4B参照)が保持されている。接地端子116は、端子部材2と同様の差込式の速結端子であって、端子ブロック45の後面に形成された接地端子孔122に対応する位置に配置されている。接地端子116は、筐体4内において、第1接地部材114及び第2接地部材115に電気的に接続されている。
Furthermore, the terminal block 45 holds a ground terminal 116 (see FIG. 4B) for connecting a ground wire. The ground terminal 116 is a plug-in quick connection terminal similar to the terminal member 2, and is disposed at a position corresponding to the ground terminal hole 122 formed on the rear surface of the terminal block 45. The ground terminal 116 is electrically connected to the first ground member 114 and the second ground member 115 in the housing 4.
温度検出部5は、1つの温度センサ51を含んでいる。温度検出部5は、筐体4内に収容されている。詳しくは「(2.2)温度検出部の構成」の欄で説明するが、温度検出部5は、複数の第1検出点と、複数の第2検出点と、の少なくとも一方を含む検出点群P100(図1B参照)の温度を、検出温度として1つの温度センサ51にて検出する。温度センサ51は、端子部材2、接続部材3、及び筐体4の内部空間40(図5A参照)等の温度を検出するためのセンサである。温度センサ51は、例えば、サーミスタ、熱電対、バイメタル又はサーモパイル等で実現される。
The temperature detection unit 5 includes one temperature sensor 51. The temperature detection unit 5 is accommodated in the housing 4. Details will be described in the section “(2.2) Configuration of Temperature Detection Unit”. The temperature detection unit 5 includes detection points including at least one of a plurality of first detection points and a plurality of second detection points. The temperature of the group P100 (see FIG. 1B) is detected by one temperature sensor 51 as the detected temperature. The temperature sensor 51 is a sensor for detecting the temperature of the terminal member 2, the connection member 3, the internal space 40 (see FIG. 5A) of the housing 4, and the like. The temperature sensor 51 is realized by a thermistor, a thermocouple, a bimetal, a thermopile, or the like, for example.
本実施形態では、温度検出部5は、センサ素子として1つの温度センサ51のみを有する。本開示でいう「センサ素子として1つの温度センサ51のみ」とは、センサ素子としては、温度センサ51の数が1つのみであることを意味し、温度検出部5が、センサ素子以外の素子(例えば基板及び電子部品等)を有することを除外する趣旨ではない。つまり、温度検出部5は、温度センサ51を1つのみ有しており、この1つの温度センサ51にて、検出点群P100に含まれる複数の検出点P1~P5(図1B参照)の温度を検出する。そのため、温度センサ51は、後述する伝熱構造50により、検出点群P100に含まれる複数の検出点P1~P5と熱的に結合されている。
In the present embodiment, the temperature detection unit 5 has only one temperature sensor 51 as a sensor element. In the present disclosure, “only one temperature sensor 51 as a sensor element” means that there is only one temperature sensor 51 as the sensor element, and the temperature detection unit 5 is an element other than the sensor element. It is not intended to exclude having (for example, a substrate and an electronic component). That is, the temperature detection unit 5 has only one temperature sensor 51, and the temperature of a plurality of detection points P1 to P5 (see FIG. 1B) included in the detection point group P100 is detected by this one temperature sensor 51. Is detected. Therefore, the temperature sensor 51 is thermally coupled to a plurality of detection points P1 to P5 included in the detection point group P100 by a heat transfer structure 50 described later.
温度検出部5は、温度センサ51で検出された検出温度に応じた検出信号を制御部7に出力する。本開示でいう「検出信号」は、特定の符号によって温度に応じた情報を伝える信号(電気信号)であればよく、例えば、温度に応じて、抵抗値、電圧値又は電流値等の電気量が変化する信号である。また、検出信号は、温度検出部5で検出される温度が閾値温度以上か閾値温度未満かによって、オン/オフ(又はハイレベル/ローレベル)の2値が切り替わる信号等であってもよい。さらに、温度検出部5は、温度センサ51の出力を処理して検出信号を出力する、処理回路を含んでいてもよい。
The temperature detection unit 5 outputs a detection signal corresponding to the detection temperature detected by the temperature sensor 51 to the control unit 7. The “detection signal” as used in the present disclosure may be a signal (electric signal) that conveys information according to temperature by a specific code. For example, an electrical quantity such as a resistance value, a voltage value, or a current value depending on the temperature. Is a signal that changes. In addition, the detection signal may be a signal that switches between ON / OFF (or high level / low level) binary values depending on whether the temperature detected by the temperature detection unit 5 is equal to or higher than the threshold temperature or lower than the threshold temperature. Furthermore, the temperature detection unit 5 may include a processing circuit that processes the output of the temperature sensor 51 and outputs a detection signal.
また、本実施形態では、伝熱構造50は、端子部材2と接続部材3との間を電気的に接続する導電部材とは別体である。本開示でいう「導電部材」は、導電性を有し、端子部材2と接続部材3との間の電流経路の少なくとも一部を構成する部材であって、例えば、リード板30、及び開閉部6の可動接触子とリード板30とを接続する編組線等を含む。要するに、伝熱構造50は、これらの導電部材(リード板30及び編組線等)とは別部材であって、端子部材2と接続部材3との間の電気的な接続は導電部材で確保されるので、伝熱構造50は導電性を有さなくてもよい。
In this embodiment, the heat transfer structure 50 is a separate body from the conductive member that electrically connects the terminal member 2 and the connection member 3. The “conductive member” in the present disclosure is a member that has conductivity and forms at least a part of a current path between the terminal member 2 and the connection member 3, and includes, for example, the lead plate 30 and the opening / closing portion. 6 including a braided wire connecting the movable contact 6 and the lead plate 30. In short, the heat transfer structure 50 is a separate member from these conductive members (such as the lead plate 30 and the braided wire), and electrical connection between the terminal member 2 and the connecting member 3 is ensured by the conductive member. Therefore, the heat transfer structure 50 may not have conductivity.
具体的には、伝熱構造50は、図5Aに示すように、筐体4の内部空間40を埋めるポッティング材にて実現される。つまり、本実施形態では、筐体4の内部空間40には、電気絶縁性を有する合成樹脂のポッティング材が充填され、ポッティング材が硬化することによって伝熱構造50を構成している。ポッティング材は、比較的高い伝熱性を有することが好ましい。伝熱構造50を構成するポッティング材は、内部空間40の少なくとも一部を埋めていればよく、内部空間40の全体を埋め尽くさなくてもよい。
Specifically, the heat transfer structure 50 is realized by a potting material that fills the internal space 40 of the housing 4 as shown in FIG. 5A. That is, in this embodiment, the internal space 40 of the housing 4 is filled with a potting material made of synthetic resin having electrical insulation, and the heat transfer structure 50 is configured by curing the potting material. The potting material preferably has a relatively high heat conductivity. The potting material constituting the heat transfer structure 50 only needs to fill at least part of the internal space 40, and does not have to fill the entire internal space 40.
(2.2)温度検出部の構成
次に、温度検出部5の構成について、図1B、図4A~図5Bを参照して詳細に説明する。 (2.2) Configuration of Temperature Detection Unit Next, the configuration of thetemperature detection unit 5 will be described in detail with reference to FIGS. 1B and 4A to 5B.
次に、温度検出部5の構成について、図1B、図4A~図5Bを参照して詳細に説明する。 (2.2) Configuration of Temperature Detection Unit Next, the configuration of the
本実施形態では、温度検出部5(図1A参照)の温度センサ51は、例えば、図5Aに示すように、筐体4の内部空間40に配置されている。具体的には、温度センサ51は、内部空間40のうち、内ブロック44の後方であって、内ブロック44から離れた位置に配置されている。より詳細には、温度センサ51は、図4Aに示すように、正面視において、内ブロック44の中心のやや上方となる位置に配置されている。つまり、正面視において、温度センサ51は、互いに異極性となる一対のリード板30の間であって、上下方向においては、リード板30で連結された互いに同極性である2個の接続部材3のうち、上方の接続部材3寄りの位置に配置されている。
In the present embodiment, the temperature sensor 51 of the temperature detection unit 5 (see FIG. 1A) is disposed in the internal space 40 of the housing 4 as shown in FIG. 5A, for example. Specifically, the temperature sensor 51 is disposed in the internal space 40 at a position behind the inner block 44 and away from the inner block 44. More specifically, as shown in FIG. 4A, the temperature sensor 51 is arranged at a position slightly above the center of the inner block 44 in a front view. That is, in the front view, the temperature sensor 51 is between the pair of lead plates 30 having different polarities, and in the vertical direction, the two connecting members 3 having the same polarity and connected by the lead plates 30. Among these, it is arranged at a position near the upper connecting member 3.
筐体4内には、一対の端子部材2と、二対(4個)の接続部材3と、が収容されている。しかも、筐体4の内部空間40には、上述したように伝熱構造50としてのポッティング材が充填されているので、温度センサ51は、伝熱構造50(ポッティング材)に埋め込まれることになる。これにより、筐体4内において、端子部材2又は接続部材3で発生した熱は、内部空間40に配置された伝熱構造50を介して温度センサ51に伝わることになる。本実施形態では、熱が上方に移動しやすいという熱の性質を考慮して、内ブロック44の中心のやや上方に温度センサ51が配置されている。
In the housing 4, a pair of terminal members 2 and two pairs (four) of connection members 3 are accommodated. Moreover, since the internal space 40 of the housing 4 is filled with the potting material as the heat transfer structure 50 as described above, the temperature sensor 51 is embedded in the heat transfer structure 50 (potting material). . Thereby, the heat generated in the terminal member 2 or the connection member 3 in the housing 4 is transmitted to the temperature sensor 51 through the heat transfer structure 50 arranged in the internal space 40. In the present embodiment, the temperature sensor 51 is disposed slightly above the center of the inner block 44 in consideration of the heat property that heat easily moves upward.
上記構成により、図1Bに示すように、端子部材2、接続部材3及び内部空間40に設けられた検出点P1~P5の温度を、温度センサ51で検出可能となる。ここで、検出点P1及び検出点P2は、それぞれ互いに異極性である一対の端子部材2の一方及び他方に設けられた検出点である。検出点P3及び検出点P4は、それぞれ互いに異極性である一対の接続部材3の一方及び他方に設けられた検出点である。検出点P5は、筐体4の内部空間40に設けられた検出点である。図1Bは、温度センサ51での温度の検出対象となる検出点群P100として、検出点P1~P5を概念的に図示しているのであって、検出点P1~P5の具体的な位置等を特定する趣旨ではない。
With the above configuration, as shown in FIG. 1B, the temperature of the detection points P1 to P5 provided in the terminal member 2, the connection member 3, and the internal space 40 can be detected by the temperature sensor 51. Here, the detection point P1 and the detection point P2 are detection points provided on one and the other of the pair of terminal members 2 having different polarities. The detection point P3 and the detection point P4 are detection points provided on one and the other of the pair of connection members 3 having different polarities. The detection point P <b> 5 is a detection point provided in the internal space 40 of the housing 4. FIG. 1B conceptually illustrates the detection points P1 to P5 as the detection point group P100 that is a temperature detection target of the temperature sensor 51, and the specific positions and the like of the detection points P1 to P5 are shown. It is not intended to identify.
これらの検出点P1~P5のうち、検出点P1及び検出点P2の組み合わせ(又は検出点P3及び検出点P4の組み合わせ)が、互いに電気的に絶縁された複数の第1検出点となる。つまり、例えば、検出点P1及び検出点P2は、それぞれ互いに異極性である一対の端子部材2の一方及び他方に設けられた検出点であるから、複数の第1の検出点に相当する。一方、検出点P1、検出点P3及び検出点P5の組み合わせ(又は検出点P2、検出点P4及び検出点P5の組み合わせ)が、端子部材2、接続部材3、及び筐体4の内部空間40のうち互いに異なる部位に設けられた複数の第2検出点となる。つまり、例えば、検出点P1、検出点P3及び検出点P5は、それぞれ端子部材2、接続部材3、及び筐体4の内部空間40に設けられた検出点であるから、複数の第2の検出点に相当する。
Among these detection points P1 to P5, a combination of the detection point P1 and the detection point P2 (or a combination of the detection point P3 and the detection point P4) becomes a plurality of first detection points that are electrically insulated from each other. That is, for example, the detection point P1 and the detection point P2 are detection points provided on one and the other of the pair of terminal members 2 having different polarities, and thus correspond to a plurality of first detection points. On the other hand, the combination of the detection point P1, the detection point P3, and the detection point P5 (or the combination of the detection point P2, the detection point P4, and the detection point P5) is a combination of the terminal member 2, the connection member 3, and the internal space 40 of the housing 4. Of these, a plurality of second detection points are provided at different sites. That is, for example, since the detection point P1, the detection point P3, and the detection point P5 are detection points provided in the internal space 40 of the terminal member 2, the connection member 3, and the casing 4, respectively, a plurality of second detection points. It corresponds to a point.
本実施形態では、1つの温度センサ51での温度の検出対象となる検出点群P100は、検出点P1~P5の全て、つまり複数の第1検出点及び複数の第2検出点の両方を含むことになる。要するに、検出点群P100は、検出点P1及び検出点P2の組み合わせ等からなる複数の第1検出点と、検出点P1、検出点P3及び検出点P5の組み合わせ等からなる複数の第2検出点と、の両方を含む。
In the present embodiment, the detection point group P100 that is a temperature detection target of one temperature sensor 51 includes all of the detection points P1 to P5, that is, both the plurality of first detection points and the plurality of second detection points. It will be. In short, the detection point group P100 includes a plurality of first detection points including a combination of the detection points P1 and P2, and a plurality of second detection points including a combination of the detection points P1, the detection points P3, and the detection points P5. And both.
ここにおいて、温度検出部5で検出される接続部材3の温度は、一例として、図5Aに示す複数の検出点P101~P111のいずれかの温度である。言い換えれば、接続部材3に設けられる検出点P3及び検出点P4の各々は、図5Aに示す複数の検出点P101~P111の中から選択される。すなわち、接続部材3の温度上昇は、接続部材3における栓刃911との接触部位が熱源となって生じることが多い。そのため、接続部材3に設けられる検出点P3又は検出点P4は、例えば、接続部材3における栓刃911との接触部位に近い検出点P101,P102,P110,P111から選択される。また、いずれか1つの接続部材3の温度上昇が生じると、接続部材3の熱は熱伝導によりリード板30、及びリード板30にて連結された他の接続部材3に伝わる。そのため、接続部材3に設けられる検出点P3又は検出点P4は、例えば、リード板30の上下方向の中央部に設定された検出点P107であってもよい。
Here, as an example, the temperature of the connection member 3 detected by the temperature detection unit 5 is any one of a plurality of detection points P101 to P111 shown in FIG. 5A. In other words, each of the detection points P3 and P4 provided on the connection member 3 is selected from the plurality of detection points P101 to P111 shown in FIG. 5A. That is, the temperature rise of the connecting member 3 often occurs due to the contact portion of the connecting member 3 with the plug blade 911 as a heat source. Therefore, the detection point P3 or the detection point P4 provided on the connection member 3 is selected from, for example, detection points P101, P102, P110, and P111 that are close to the contact part with the plug blade 911 on the connection member 3. Moreover, when the temperature rise of any one connection member 3 arises, the heat of the connection member 3 will be transmitted to the other connection member 3 connected with the lead plate 30 and the lead plate 30 by heat conduction. Therefore, the detection point P3 or the detection point P4 provided on the connection member 3 may be, for example, the detection point P107 set at the center in the vertical direction of the lead plate 30.
さらに、接続部材3の温度上昇が生じると、接続部材3を保持する保持部材には、接続部材3又はリード板30からの熱が伝わることがある。特に、本実施形態のように、保持部材が内ブロック44及び外カバー42等の合成樹脂製の部材である場合には、保持部材(内ブロック44及び外カバー42)の特性が熱による影響を受け、保持部材の特性が変化(変質、変色及び変形を含む)することがある。そのため、接続部材3に設けられる検出点P3又は検出点P4は、例えば、接続部材3及びリード板30における保持部材(内ブロック44及び外カバー42)との接触部位に近い検出点P105,P106,P108,P109から選択されてもよい。
Furthermore, when the temperature of the connection member 3 rises, heat from the connection member 3 or the lead plate 30 may be transmitted to the holding member that holds the connection member 3. In particular, when the holding member is a synthetic resin member such as the inner block 44 and the outer cover 42 as in this embodiment, the characteristics of the holding members (the inner block 44 and the outer cover 42) are affected by heat. The characteristics of the receiving and holding members may change (including alteration, discoloration, and deformation). Therefore, the detection point P3 or the detection point P4 provided on the connection member 3 is, for example, the detection points P105, P106, which are close to the contact portions of the connection member 3 and the lead plate 30 with the holding members (the inner block 44 and the outer cover 42). P108 and P109 may be selected.
また、温度検出部5で検出される端子部材2の温度は、一例として、図5Bに示す複数の検出点P121~P125のいずれかの温度である。すなわち、端子部材2の温度上昇は、端子部材2における心線921との接触部位が熱源となって生じることが多い。そのため、端子部材2に設けられる検出点P1又は検出点P2は、例えば、端子部材2における心線921との接触部位に近い検出点P124,P125から選択される。また、端子部材2の温度上昇が生じると、その熱は熱伝導により端子板21の全体に伝わる。そのため、端子部材2に設けられる検出点P1又は検出点P2は、例えば、端子板21における心線921との接触部位から離れた検出点P122であってもよい。
Further, the temperature of the terminal member 2 detected by the temperature detection unit 5 is, for example, any one of a plurality of detection points P121 to P125 shown in FIG. 5B. That is, the temperature rise of the terminal member 2 is often caused by the contact portion of the terminal member 2 with the core wire 921 as a heat source. Therefore, the detection point P1 or the detection point P2 provided on the terminal member 2 is selected from, for example, detection points P124 and P125 close to the contact portion with the core wire 921 in the terminal member 2. Further, when the temperature of the terminal member 2 rises, the heat is transmitted to the entire terminal board 21 by heat conduction. Therefore, the detection point P <b> 1 or the detection point P <b> 2 provided on the terminal member 2 may be, for example, the detection point P <b> 122 that is away from the contact portion with the core wire 921 on the terminal plate 21.
また、端子部材2の温度上昇が生じると、端子部材2を保持する保持部材には、端子部材2からの熱が伝わることがある。特に、本実施形態のように、保持部材が端子ブロック45等の合成樹脂製の部材である場合には、保持部材(端子ブロック45)の特性が熱による影響を受け、保持部材の特性が変化(変質、変色及び変形を含む)することがある。そのため、端子部材2に設けられる検出点P1又は検出点P2は、例えば、端子部材2における保持部材(端子ブロック45)との接触部位に近い検出点P121,P123から選択されてもよい。
Further, when the temperature of the terminal member 2 rises, heat from the terminal member 2 may be transmitted to the holding member that holds the terminal member 2. In particular, when the holding member is a synthetic resin member such as the terminal block 45 as in this embodiment, the characteristics of the holding member (terminal block 45) are affected by heat and the characteristics of the holding member change. (Including alteration, discoloration and deformation). Therefore, the detection point P1 or the detection point P2 provided in the terminal member 2 may be selected from the detection points P121 and P123 close to the contact portion with the holding member (terminal block 45) in the terminal member 2, for example.
さらに、接続部材3の温度上昇が生じると、接続部材3又はリード板30からの放熱により、筐体4の内部空間40(図5A参照)の温度も上昇する。同様に、端子部材2の温度上昇が生じると、端子板21又は鎖錠ばね22からの放熱により、筐体4の内部空間40の温度も上昇する。そのため、温度検出部5は、接続部材3、リード板30又は端子部材2上ではなく、筐体4の内部空間40に設定された検出点P112,P113,P114(図5A参照)等の温度を検出することで、間接的に接続部材3又は端子部材2の温度を検出してもよい。つまり、筐体4の内部空間40に設けられた検出点P5は、例えば、検出点P112,P113,P114から選択される。
Furthermore, when the temperature of the connection member 3 increases, the temperature of the internal space 40 (see FIG. 5A) of the housing 4 also increases due to heat radiation from the connection member 3 or the lead plate 30. Similarly, when the temperature of the terminal member 2 rises, the temperature of the internal space 40 of the housing 4 also rises due to heat radiation from the terminal plate 21 or the lock spring 22. Therefore, the temperature detector 5 detects the temperatures of the detection points P112, P113, P114 (see FIG. 5A) set in the internal space 40 of the housing 4 instead of on the connection member 3, the lead plate 30, or the terminal member 2. By detecting, the temperature of the connection member 3 or the terminal member 2 may be detected indirectly. That is, the detection point P5 provided in the internal space 40 of the housing 4 is selected from the detection points P112, P113, and P114, for example.
図5A及び図5Bに示す、温度センサ51の配置、並びに検出点P101~P114,P121~P125の位置は一例に過ぎず、適宜変更可能である。
The arrangement of the temperature sensor 51 and the positions of the detection points P101 to P114 and P121 to P125 shown in FIGS. 5A and 5B are merely examples, and can be changed as appropriate.
ところで、上述したように、温度検出部5が1つの温度センサ51にて、端子部材2、接続部材3及び内部空間40に設けられた検出点P1~P5の温度を検出する場合、例えば、以下のような構成で、検出点P1~P5の温度を区別可能である。
By the way, as described above, when the temperature detection unit 5 detects the temperatures of the detection points P1 to P5 provided in the terminal member 2, the connection member 3, and the internal space 40 with one temperature sensor 51, for example, With such a configuration, the temperatures of the detection points P1 to P5 can be distinguished.
すなわち、上述したように、例えば、接続部材3の温度上昇は、接続部材3における栓刃911との接触部位が熱源となって生じることが多く、一方で、端子部材2の温度上昇は、端子部材2における心線921との接触部位が熱源となって生じることが多い。さらに、筐体4の内部空間40の温度上昇は、端子部材2又は接続部材3の温度上昇に起因して生じる。そのため、端子部材2に設けられた検出点P1,P2と、接続部材3に設けられた検出点P3,P4と、筐体4の内部空間40に設けられた検出点P5とでは、温度変化の振る舞いが相違する。したがって、温度検出部5又は制御部7は、温度センサ51の出力に対する解析処理を行うことで、検出点P1~P5の温度を区別することが可能である。
That is, as described above, for example, the temperature rise of the connection member 3 often occurs due to the contact portion of the connection member 3 with the plug blade 911 being a heat source, while the temperature rise of the terminal member 2 is In many cases, the contact portion of the member 2 with the core wire 921 is a heat source. Furthermore, the temperature rise in the internal space 40 of the housing 4 is caused by the temperature rise in the terminal member 2 or the connection member 3. Therefore, the detection points P1, P2 provided on the terminal member 2, the detection points P3, P4 provided on the connection member 3, and the detection point P5 provided on the internal space 40 of the housing 4 are subject to temperature changes. The behavior is different. Therefore, the temperature detection unit 5 or the control unit 7 can distinguish the temperatures of the detection points P1 to P5 by performing analysis processing on the output of the temperature sensor 51.
一例として、コンセントシステム10への通電開始直後、つまりコンセントシステム10の起動直後において、数秒の間に急激に温度が上昇した場合には端子部材2に設けられた検出点P1,P2の温度上昇と推定される。一方、コンセントシステム10への通電開始から所定時間経過後において、数秒の間に急激に温度が上昇した場合には接続部材3に設けられた検出点P3,P4の温度上昇と推定される。また、1時間の間に徐々に温度が上昇した場合には筐体4の内部空間40に設けられた検出点P5の温度上昇と推定される。
As an example, immediately after the start of energization of the outlet system 10, that is, immediately after the activation of the outlet system 10, if the temperature suddenly rises within a few seconds, the temperature rises at the detection points P1 and P2 provided on the terminal member 2 Presumed. On the other hand, if the temperature suddenly rises within a few seconds after the start of energization of the outlet system 10, it is estimated that the temperature of the detection points P3 and P4 provided on the connecting member 3 has risen. Further, when the temperature gradually increases during one hour, it is estimated that the temperature of the detection point P5 provided in the internal space 40 of the housing 4 is increased.
(2.3)動作
次に、本実施形態に係るコンセントシステム10の動作について説明する。 (2.3) Operation Next, the operation of theoutlet system 10 according to the present embodiment will be described.
次に、本実施形態に係るコンセントシステム10の動作について説明する。 (2.3) Operation Next, the operation of the
コンセントシステム10の基本的な動作として、開閉部6は、判定条件を満たしたときに、導通状態から遮断状態に切り替わるように動作する。判定条件は、検出温度が閾値温度以上であることを含んでいる。ここで、検出温度は、温度検出部5で検出された端子部材2と接続部材3との少なくとも一方の温度である。開閉部6は、判定条件を満たさない場合において、遮断状態から導通状態に切替可能である。
As a basic operation of the outlet system 10, the opening / closing unit 6 operates so as to switch from the conductive state to the cut-off state when the determination condition is satisfied. The determination condition includes that the detected temperature is equal to or higher than the threshold temperature. Here, the detected temperature is the temperature of at least one of the terminal member 2 and the connection member 3 detected by the temperature detection unit 5. The opening / closing part 6 can be switched from the cut-off state to the conductive state when the determination condition is not satisfied.
本開示でいう「遮断状態から導通状態に切替可能」とは、遮断状態から導通状態への開閉部6の切替えが許容された状態、つまり遮断状態にある開閉部6を導通状態へ切り替えることが許容された状態を意味する。そのため、「遮断状態から導通状態に切替可能」でなければ、遮断状態にある開閉部6は導通状態への切替えが禁止され、遮断状態を維持することになる。ここで、遮断状態から導通状態への開閉部6の切替えは、ユーザが手動で行ってもよいし、例えば、コンセント1の外部からの復旧信号を受信する、又は所定時間が経過する等の復旧条件を満たした場合に、コンセントシステム10が自動で行ってもよい。
In the present disclosure, “can be switched from the cut-off state to the conductive state” means that the switching of the opening / closing unit 6 from the cut-off state to the conductive state is permitted, that is, switching the open / close unit 6 in the cut-off state to the conductive state. It means an allowed state. For this reason, unless it is “switchable from the cut-off state to the conductive state”, the switching unit 6 in the cut-off state is prohibited from switching to the conductive state and maintains the cut-off state. Here, the switching of the opening / closing unit 6 from the cut-off state to the conductive state may be performed manually by the user, or for example, a recovery signal from the outside of the outlet 1 is received, or a recovery such as a predetermined time elapses. When the condition is satisfied, the outlet system 10 may perform automatically.
本実施形態では、制御部7が、温度検出部5からの検出信号を受信することにより、検出温度を取得する。そして、制御部7は、メモリ等に記憶されている閾値温度と検出温度との比較を行い、判定条件の判定を行う。制御部7は、判定条件を満たすと判断した場合に、開閉部6に駆動信号を出力し、開閉部6を導通状態から遮断状態に切り替える。また、本実施形態では一例として、判定条件は、検出温度が閾値温度以上であることのみとする。つまり、検出温度が閾値温度以上であれば判定条件を満たし、検出温度が閾値温度未満であれば判定条件を満たさない。
In the present embodiment, the control unit 7 receives the detection signal from the temperature detection unit 5 to acquire the detected temperature. Then, the control unit 7 compares the threshold temperature stored in the memory or the like with the detected temperature, and determines the determination condition. When it is determined that the determination condition is satisfied, the control unit 7 outputs a drive signal to the opening / closing unit 6 and switches the opening / closing unit 6 from the conductive state to the cutoff state. In the present embodiment, as an example, the determination condition is that the detected temperature is not less than the threshold temperature. That is, the determination condition is satisfied if the detected temperature is equal to or higher than the threshold temperature, and the determination condition is not satisfied if the detected temperature is lower than the threshold temperature.
ここにおいて、本実施形態では、温度検出部5は、接続部材3の温度を検出温度として検出し、かつ端子部材2の温度を補助検出温度として検出する。開閉部6は、補助検出温度が補助閾値温度以上であることを含む補助判定条件を満たしたときには、導通状態から遮断状態に切り替わり、遮断状態から導通状態への切替えが制限される。すなわち、本実施形態では、温度検出部5は、端子部材2及び接続部材3のうち、接続部材3の温度のみを検出温度として検出し、端子部材2の温度については、検出温度とは別の補助検出温度として検出する。
Here, in the present embodiment, the temperature detection unit 5 detects the temperature of the connection member 3 as a detection temperature, and detects the temperature of the terminal member 2 as an auxiliary detection temperature. When the auxiliary detection condition including that the auxiliary detection temperature is equal to or higher than the auxiliary threshold temperature is satisfied, the opening / closing unit 6 switches from the conduction state to the cutoff state, and switching from the cutoff state to the conduction state is limited. That is, in this embodiment, the temperature detection unit 5 detects only the temperature of the connection member 3 among the terminal member 2 and the connection member 3 as the detection temperature, and the temperature of the terminal member 2 is different from the detection temperature. Detect as auxiliary detection temperature.
そのため、端子部材2及び接続部材3のうち、接続部材3の温度に関してのみ、判定条件を満たしたときに、開閉部6が導通状態から遮断状態に切り替わり、かつ判定条件を満たさない場合において、開閉部6が遮断状態から導通状態に切替可能となる。端子部材2の温度(補助検出温度)に関しては、補助判定条件を満たしたときに、開閉部6が導通状態から遮断状態に切り替わるものの、遮断状態から導通状態への切替えが制限される。つまり、補助検出温度が補助判定条件を満たした場合には、補助判定条件を満たさなくなっても、遮断状態から導通状態への開閉部6の切替えは制限(例えば禁止)される。
Therefore, of the terminal member 2 and the connection member 3, when the determination condition is satisfied only with respect to the temperature of the connection member 3, the opening / closing part 6 is switched from the conductive state to the cutoff state, and the opening / closing is not performed when the determination condition is not satisfied. The part 6 can be switched from the cut-off state to the conductive state. Regarding the temperature of the terminal member 2 (auxiliary detection temperature), when the auxiliary determination condition is satisfied, the switching unit 6 is switched from the conductive state to the cut-off state, but switching from the cut-off state to the conductive state is limited. That is, when the auxiliary detection temperature satisfies the auxiliary determination condition, even if the auxiliary determination condition is not satisfied, switching of the opening / closing unit 6 from the cutoff state to the conduction state is restricted (for example, prohibited).
本実施形態では一例として、補助判定条件は、判定条件と同様に補助検出温度が補助閾値温度以上であることのみとする。つまり、補助検出温度が補助閾値温度以上であれば補助判定条件を満たし、補助検出温度が補助閾値温度未満であれば判定条件を満たさない。報知部71による報知を行うか否かの判定に使用される注意判定条件についても同様に、本実施形態では、検出温度が注意温度以上であることのみとする。つまり、検出温度が注意度以上であれば注意判定条件を満たし、検出温度が注意温度未満であれば注意判定条件を満たさない。
In the present embodiment, as an example, the auxiliary determination condition is that the auxiliary detection temperature is equal to or higher than the auxiliary threshold temperature as in the determination condition. That is, if the auxiliary detection temperature is equal to or higher than the auxiliary threshold temperature, the auxiliary determination condition is satisfied, and if the auxiliary detection temperature is lower than the auxiliary threshold temperature, the determination condition is not satisfied. Similarly, with regard to the caution determination condition used for determining whether to perform notification by the notification unit 71, in the present embodiment, it is assumed that the detected temperature is not less than the caution temperature. That is, if the detected temperature is higher than the caution level, the caution determination condition is satisfied, and if the detected temperature is lower than the caution temperature, the caution determination condition is not satisfied.
また、本実施形態では、表示部82の表示態様としては、第1表示灯821及び第2表示灯822の点灯状態(消灯、点灯又は点滅等)の組み合わせにより、複数パターンの表示態様がある。例えば、表示部82は、開閉部6が導通状態にある定常時には第1表示灯821を点灯、第2表示灯822を消灯させることで「正常」の表示を行う。一方、温度検出部5での検出温度が閾値温度より低い注意温度以上であることを含む注意判定条件を満たしたときには、表示部82は、第1表示灯821を点灯、第2表示灯822を点滅させることで「注意」の表示を行う。さらに、開閉部6が導通状態から遮断状態に切り替わると、表示部82は、第1表示灯821を点灯、第2表示灯822を点灯させることで「警告」の表示を行う。
Further, in the present embodiment, as the display mode of the display unit 82, there are a plurality of patterns of display modes depending on the combination of the lighting states of the first indicator lamp 821 and the second indicator lamp 822 (light-off, lighting or blinking, etc.). For example, the display unit 82 displays “normal” by turning on the first indicator lamp 821 and turning off the second indicator lamp 822 in a steady state when the open / close unit 6 is in a conductive state. On the other hand, when the caution determination condition including that the temperature detected by the temperature detection unit 5 is equal to or higher than the caution temperature lower than the threshold temperature is satisfied, the display unit 82 turns on the first display lamp 821 and turns on the second display lamp 822. “Caution” is displayed by blinking. Further, when the opening / closing unit 6 is switched from the conductive state to the cut-off state, the display unit 82 displays the “warning” by turning on the first indicator lamp 821 and turning on the second indicator lamp 822.
同様に、ブザー83からの出力音の態様としても、報知部71での報知を実現する注意音、及び状態提示部72での提示を実現する警告音を含む、複数パターンの態様がある。すなわち、ブザー83は、開閉部6が導通状態にある定常時には停止しており、温度検出部5での検出温度が閾値温度より低い注意温度以上であることを含む注意判定条件を満たしたときに、注意音を出力する。さらに、開閉部6が導通状態から遮断状態に切り替わると、ブザー83は、注意音とは別の警告音を出力する。
Similarly, the form of the output sound from the buzzer 83 includes a plurality of patterns including a warning sound that realizes notification by the notification unit 71 and a warning sound that realizes presentation by the state presentation unit 72. That is, the buzzer 83 is stopped at a steady time when the opening / closing unit 6 is in a conductive state, and when the caution determination condition including that the temperature detected by the temperature detection unit 5 is equal to or higher than the caution temperature lower than the threshold temperature is satisfied. , Output a warning sound. Further, when the opening / closing part 6 is switched from the conductive state to the cut-off state, the buzzer 83 outputs a warning sound different from the caution sound.
また、本実施形態では、閾値温度は、保持部材の特性が所定の変化をするときの検出温度未満に設定されている。つまり、上述したように、接続部材3を保持する保持部材(内ブロック44及び外カバー42)には、接続部材3からの熱が伝わることがあり、保持部材の特性が熱による影響を受けて、保持部材の特性が変化(変質、変色及び変形を含む)することがある。一方で、本実施形態に係るコンセントシステム10では、温度上昇が生じた後であっても、コンセント1を再使用可能とするため、保持部材の特性が許容範囲を超えないように、開閉部6を遮断することが好ましい。本開示でいう「所定の変化」とは、保持部材の特性の変化において許容範囲の上限となるときの変化である。例えば、特定の規格において保持部材の特性の許容範囲が定められている場合、温度上昇が生じたとしても、保持部材の特性がこの許容範囲内で収まることが好ましい。そこで、保持部材の特性が所定の変化をするときの検出温度未満の温度を閾値温度とすることで、保持部材の特性に所定の変化以上の変化が生じる前に、開閉部6を遮断状態とすることが可能である。これにより、保持部材の特性が劣化する前に、開閉部6を遮断状態として更なる温度上昇を抑制し、コンセント1の再使用に備えることができる。
Further, in the present embodiment, the threshold temperature is set to be lower than the detected temperature when the characteristics of the holding member undergo a predetermined change. That is, as described above, heat from the connection member 3 may be transmitted to the holding members (the inner block 44 and the outer cover 42) that hold the connection member 3, and the characteristics of the holding member are affected by the heat. The characteristics of the holding member may change (including alteration, discoloration, and deformation). On the other hand, in the outlet system 10 according to the present embodiment, since the outlet 1 can be reused even after the temperature rises, the opening / closing portion 6 is provided so that the characteristics of the holding member do not exceed the allowable range. Is preferably blocked. The “predetermined change” in the present disclosure is a change when the upper limit of the allowable range is reached in the change in the characteristics of the holding member. For example, when the allowable range of the characteristics of the holding member is defined in a specific standard, it is preferable that the characteristics of the holding member fall within the allowable range even if the temperature rises. Therefore, by setting the temperature lower than the detection temperature when the characteristics of the holding member change to a predetermined value as the threshold temperature, the opening / closing portion 6 is set in the shut-off state before the change of the characteristics of the holding member exceeds the predetermined change. Is possible. Thereby, before the characteristic of a holding member deteriorates, the further temperature rise can be suppressed by making the opening-and-closing part 6 into a cutoff state, and the outlet 1 can be prepared for reuse.
また、本実施形態に係るコンセントシステム10は、上述したようにユーザからの操作を受け付ける操作部材81を備え、この操作部材81を開閉部6と連動させている。そのため、開閉部6は、判定条件を満たさない場合における操作部材81の操作(復旧操作)により、遮断状態から導通状態に切り替わることになる。つまり、判定条件を満たして開閉部6が導通状態から遮断状態に切り替わった後に、判定条件を満たした要因が解消し、判定条件を満たさなくなった状態で復旧操作が行われると、開閉部6が遮断状態から導通状態に切り替わる。これにより、ユーザは、手動にて開閉部6を遮断状態から導通状態に切り替えることが可能である。
Also, the outlet system 10 according to the present embodiment includes the operation member 81 that receives an operation from the user as described above, and the operation member 81 is linked to the opening / closing unit 6. Therefore, the opening / closing part 6 is switched from the cut-off state to the conductive state by the operation (recovery operation) of the operation member 81 when the determination condition is not satisfied. That is, after the opening / closing unit 6 is switched from the conductive state to the shut-off state after satisfying the determination condition, if the factor satisfying the determination condition is resolved and the restoration operation is performed in a state where the determination condition is not satisfied, the opening / closing unit 6 Switch from the interrupted state to the conductive state. Thereby, the user can manually switch the opening / closing part 6 from the cut-off state to the conductive state.
また、本実施形態では、上述したように、操作部材81が開閉部6に連動してオン位置とオフ位置との間で移動する。つまり、操作部材81の位置によっても開閉部6が導通状態にあるか遮断状態にあるかは提示されるため、操作部材81もまた、開閉部6の状態を提示する状態提示部として機能する。本実施形態では、操作部材81のうち、操作部材81がオフ位置にある場合にのみ視認可能となる部位に、赤色等の着色がされていることで、操作部材81がオン位置とオフ位置とのいずれにあるかが、遠目でも視認可能である。
In this embodiment, as described above, the operation member 81 moves between the on position and the off position in conjunction with the opening / closing portion 6. That is, since whether the opening / closing unit 6 is in the conductive state or the blocking state is also indicated depending on the position of the operation member 81, the operation member 81 also functions as a state presentation unit that presents the state of the opening / closing unit 6. In the present embodiment, a portion of the operation member 81 that is visible only when the operation member 81 is in the off position is colored red or the like, so that the operation member 81 has an on position and an off position. It can be visually recognized from a distance.
以下、本実施形態に係るコンセントシステム10の動作の一例について、図6のフローチャートを参照して説明する。また、図6のフローチャートは一例に過ぎず、処理の順番が適宜変更されてもよいし、処理が適宜追加又は省略されてもよい。
Hereinafter, an example of the operation of the outlet system 10 according to the present embodiment will be described with reference to the flowchart of FIG. Moreover, the flowchart of FIG. 6 is only an example, the order of processing may be changed as appropriate, and processing may be added or omitted as appropriate.
図6において、まず、制御部7が温度検出部5から検出信号を受信することにより、実測温度T1を取得する(S1)。実測温度T1は、接続部材3の温度(検出温度)と端子部材2の温度(補助検出温度)との両方を含んでいる。
6, first, the control unit 7 receives the detection signal from the temperature detection unit 5 to acquire the actually measured temperature T1 (S1). The measured temperature T1 includes both the temperature of the connecting member 3 (detected temperature) and the temperature of the terminal member 2 (auxiliary detected temperature).
次に、制御部7は、実測温度T1と注意温度Tth1とを比較する(S2)。注意温度Tth1は、注意判定条件を満たすか否か、つまり報知部71による報知を行うか否かの判定のために、検出温度と比較される温度である。注意温度Tth1は、閾値温度Tth2よりも低い温度である。実測温度T1が注意温度Tth1未満であれば(S2:No)、制御部7は、注意判定条件を満たさないと判断し、ブザー83の停止処理(S3)、及び表示部82での「正常」表示(S4)を実行し、処理S1に戻る。
Next, the control unit 7 compares the measured temperature T1 with the caution temperature Tth1 (S2). The caution temperature Tth1 is a temperature that is compared with the detected temperature in order to determine whether the caution determination condition is satisfied, that is, whether the notification by the notification unit 71 is performed. The attention temperature Tth1 is a temperature lower than the threshold temperature Tth2. If the measured temperature T1 is less than the caution temperature Tth1 (S2: No), the control unit 7 determines that the caution determination condition is not satisfied, the buzzer 83 stop processing (S3), and “normal” on the display unit 82. Display (S4) is executed, and the process returns to step S1.
一方、処理S2にて、実測温度T1が注意温度Tth1以上であれば(S2:Yes)、制御部7は、注意判定条件を満たすと判断し、報知部71での報知、つまりブザー83からの注意音の出力(S5)、及び表示部82での「注意」表示を行う(S6)。この状態で、スイッチ84が押操作される、つまりブザー83の停止ボタンが押されると(S7:Yes)、制御部7は、ブザー83の停止処理(S8)を実行し、実測温度T1を取得する(S9)。スイッチ84が押操作されない、つまりブザー83の停止ボタンが押されなければ(S7:No)、制御部7は、ブザー83の停止処理(S8)をスキップして、実測温度T1を取得する(S9)。
On the other hand, if the measured temperature T1 is equal to or higher than the caution temperature Tth1 in step S2 (S2: Yes), the control unit 7 determines that the caution determination condition is satisfied, and the notification from the notification unit 71, that is, from the buzzer 83, is performed. A warning sound is output (S5), and a "caution" is displayed on the display unit 82 (S6). In this state, when the switch 84 is pressed, that is, when the stop button of the buzzer 83 is pressed (S7: Yes), the control unit 7 executes the stop process (S8) of the buzzer 83 and acquires the measured temperature T1. (S9). If the switch 84 is not pressed, that is, if the stop button of the buzzer 83 is not pressed (S7: No), the control unit 7 skips the stop process (S8) of the buzzer 83 and acquires the measured temperature T1 (S9). ).
次に、制御部7は、処理S9で取得した実測温度T1と閾値温度Tth2とを比較する(S10)。閾値温度Tth2は、判定条件を満たすか否か、つまり開閉部6を遮断状態とするか否かの判定のために、検出温度と比較される温度である。さらに、本実施形態では、閾値温度Tth2は、補助判定条件を満たすか否かの判定のために、補助検出温度と比較される補助閾値温度を兼ねている。つまり、補助閾値温度は閾値温度Tth2と等しい。実測温度T1が閾値温度Tth2未満であれば(S10:No)、制御部7は、判定条件及び補助判定条件を満たさないと判断し、処理S1に戻る。
Next, the control unit 7 compares the measured temperature T1 acquired in the process S9 with the threshold temperature Tth2 (S10). The threshold temperature Tth2 is a temperature that is compared with the detected temperature in order to determine whether or not the determination condition is satisfied, that is, whether or not the opening / closing unit 6 is in the shut-off state. Further, in the present embodiment, the threshold temperature Tth2 also serves as an auxiliary threshold temperature that is compared with the auxiliary detection temperature in order to determine whether or not the auxiliary determination condition is satisfied. That is, the auxiliary threshold temperature is equal to the threshold temperature Tth2. If the measured temperature T1 is less than the threshold temperature Tth2 (S10: No), the control unit 7 determines that the determination condition and the auxiliary determination condition are not satisfied, and returns to the process S1.
そのため、一度、注意判定条件を満たすと判断されて報知部71による報知が行われた場合でも、その後に、実測温度T1が低下し注意温度Tth1を下回れば(S2:No)、ブザー83の停止処理(S3)、及び表示部82での「正常」表示(S4)が行われる。したがって、例えば、一過性の事象に起因する温度上昇が生じ、実測温度T1が低下し注意温度Tth1以上と判断された場合でも、その後、実測温度T1が低下すれば、自動的に報知部71による報知は停止する。
For this reason, even if it is determined that the caution determination condition is satisfied once and the notification by the notification unit 71 is made, if the measured temperature T1 decreases and falls below the caution temperature Tth1 (S2: No), the buzzer 83 is stopped. Processing (S3) and “normal” display (S4) on the display unit 82 are performed. Therefore, for example, even if a temperature increase due to a transient event occurs and the measured temperature T1 is decreased and determined to be equal to or higher than the caution temperature Tth1, if the measured temperature T1 subsequently decreases, the notification unit 71 automatically. Notification by is stopped.
一方、処理S10にて、実測温度T1が閾値温度Tth2以上であれば(S10:Yes)、制御部7は、判定条件又は補助判定条件を満たすと判断し、開閉部6に駆動信号を出力し、開閉部6を導通状態から遮断状態に切り替える(S11)。その後、制御部7は、状態提示部72での提示、つまりブザー83からの警告音の出力(S12)、及び表示部82での「警告」表示を行う(S13)。この状態で、スイッチ84が押操作される、つまりブザー83の停止ボタンが押されると(S14:Yes)、制御部7は、ブザー83の停止処理(S15)を実行し、処理S16に移行する。スイッチ84が押操作されない、つまりブザー83の停止ボタンが押されなければ(S14:No)、制御部7は、ブザー83の停止処理(S15)をスキップして、処理S16に移行する。
On the other hand, if the measured temperature T1 is equal to or higher than the threshold temperature Tth2 in step S10 (S10: Yes), the control unit 7 determines that the determination condition or the auxiliary determination condition is satisfied, and outputs a drive signal to the opening / closing unit 6. Then, the opening / closing part 6 is switched from the conduction state to the cutoff state (S11). Thereafter, the control unit 7 presents the state presentation unit 72, that is, outputs a warning sound from the buzzer 83 (S12), and displays a “warning” on the display unit 82 (S13). In this state, when the switch 84 is pressed, that is, when the stop button of the buzzer 83 is pressed (S14: Yes), the control unit 7 executes the stop process (S15) of the buzzer 83 and proceeds to the process S16. . If the switch 84 is not pressed, that is, if the stop button of the buzzer 83 is not pressed (S14: No), the controller 7 skips the stop process (S15) of the buzzer 83 and proceeds to process S16.
処理S16では、制御部7は、閾値温度Tth2以上と判定された実測温度T1が、接続部材3の温度か否かを判断する。つまり、このときの実測温度T1が、接続部材3の温度であれば(S16:Yes)、処理S10において、判定条件を満たすと判断されたことになるので、制御部7は、開閉部6を遮断状態から導通状態へ切替可能な処理S17に移行する。この状態で、操作部材81の復旧操作が行われると(S17:Yes)、開閉部6が遮断状態から導通状態へ切り替わり(S18)、処理S9に移行する。このとき、判定条件の要因が解消していない、つまり実測温度T1が依然として閾値温度Tth2以上であれば(S10:Yes)、制御部7は、即座に開閉部6を導通状態から遮断状態に切り替える(S11)。一方、判定条件の要因が解消し、実測温度T1が閾値温度Tth2未満であれば(S10:No)、制御部7は、判定条件及び補助判定条件を満たさないと判断し、処理S1に戻る。これにより、開閉部6は導通状態を維持し、コンセント1は再使用可能な状態となる。
In process S16, the control unit 7 determines whether or not the measured temperature T1 determined to be equal to or higher than the threshold temperature Tth2 is the temperature of the connection member 3. That is, if the actually measured temperature T1 at this time is the temperature of the connecting member 3 (S16: Yes), it is determined that the determination condition is satisfied in the process S10. The process proceeds to processing S17 that can be switched from the cutoff state to the conductive state. In this state, when the restoration operation of the operation member 81 is performed (S17: Yes), the opening / closing part 6 is switched from the cut-off state to the conductive state (S18), and the process proceeds to step S9. At this time, if the factor of the determination condition is not eliminated, that is, if the actually measured temperature T1 is still equal to or higher than the threshold temperature Tth2 (S10: Yes), the control unit 7 immediately switches the opening / closing unit 6 from the conduction state to the cutoff state. (S11). On the other hand, if the factor of the determination condition is eliminated and the measured temperature T1 is less than the threshold temperature Tth2 (S10: No), the control unit 7 determines that the determination condition and the auxiliary determination condition are not satisfied, and returns to the process S1. Thereby, the opening / closing part 6 maintains a conductive state, and the outlet 1 becomes reusable.
一方、処理S16にて、閾値温度Tth2以上と判定された実測温度T1が、接続部材3の温度でないと判断された場合(S16:No)、処理S10において、補助判定条件を満たすと判断されたことになる。この場合、制御部7は、開閉部6を遮断状態から導通状態へ切替不可能な処理S19に移行する。この状態で、操作部材81の復旧操作が行われると(S19:Yes)、制御部7は、駆動信号により強制的に開閉部6を遮断状態に維持する(S11)。
On the other hand, when it is determined in process S16 that the measured temperature T1 determined to be equal to or higher than the threshold temperature Tth2 is not the temperature of the connecting member 3 (S16: No), it is determined in process S10 that the auxiliary determination condition is satisfied. It will be. In this case, the control unit 7 proceeds to a process S19 in which the opening / closing unit 6 cannot be switched from the cutoff state to the conductive state. In this state, when the restoration operation of the operation member 81 is performed (S19: Yes), the control unit 7 forcibly maintains the open / close unit 6 in the shut-off state by the drive signal (S11).
また、処理S17及び処理S19のいずれにおいても、復旧操作が行われなければ(S17No又はS19:No)、制御部7は、処理S14に移行する。
Further, in any of the processing S17 and the processing S19, if the restoration operation is not performed (No in S17 or S19), the control unit 7 proceeds to the processing S14.
上記コンセントシステム10では、判定条件を満たさない場合、開閉部6は遮断状態から導通状態に切替可能である。すなわち、コンセントシステム10においては、判定条件を満たすことによって、開閉部6が一度、遮断状態になっても、その後、判定条件を満たした要因が解消することにより、判定条件を満たさなくなると、開閉部6を導通状態に復帰させることが可能である。したがって、コンセントシステム10によれば、開閉部6が一度遮断状態になっても、開閉部6を復旧させることで、コンセントシステム10(コンセント1)を交換することなく、コンセントシステム10(コンセント1)を再使用することができる。そのため、例えば、温度上昇が、一過性の事象に起因する場合、又はコンセント1に接続されている電気機器に起因する場合等、コンセント1の交換が本来不要な場合には、コンセント1の交換が不要であり、コンセントシステム10としての利便性が向上する。
In the outlet system 10, when the determination condition is not satisfied, the opening / closing part 6 can be switched from the cut-off state to the conduction state. That is, in the outlet system 10, if the determination condition is satisfied, even if the opening / closing unit 6 is once in a shut-off state, the factor that satisfies the determination condition is eliminated. It is possible to return the part 6 to the conductive state. Therefore, according to the outlet system 10, the outlet system 10 (outlet 1) can be recovered without replacing the outlet system 10 (outlet 1) by restoring the opening and closing unit 6 even if the opening and closing unit 6 is once cut off. Can be reused. Therefore, for example, when the temperature rise is due to a transient event or due to an electrical device connected to the outlet 1, the replacement of the outlet 1 is not necessary when the replacement of the outlet 1 is essentially unnecessary. Is not necessary, and convenience as the outlet system 10 is improved.

以下、上記実施形態の変形例を列挙する。以下に説明する変形例は、適宜組み合わせて適用可能である。
Hereinafter, modifications of the above embodiment will be listed. The modifications described below can be applied in appropriate combinations.
本開示におけるコンセントシステム10は、例えば、制御部7等に、コンピュータシステムを含んでいる。コンピュータシステムは、ハードウェアとしてのプロセッサ及びメモリを主構成とする。コンピュータシステムのメモリに記録されたプログラムをプロセッサが実行することによって、本開示における制御部7としての機能が実現される。プログラムは、コンピュータシステムのメモリに予め記録されてもよく、電気通信回線を通じて提供されてもよく、コンピュータシステムで読み取り可能なメモリカード、光学ディスク、ハードディスクドライブ等の非一時的記録媒体に記録されて提供されてもよい。コンピュータシステムのプロセッサは、半導体集積回路(IC)又は大規模集積回路(LSI)を含む1ないし複数の電子回路で構成される。複数の電子回路は、1つのチップに集約されていてもよいし、複数のチップに分散して設けられていてもよい。複数のチップは、1つの装置に集約されていてもよいし、複数の装置に分散して設けられていてもよい。
The outlet system 10 in the present disclosure includes a computer system in the control unit 7 or the like, for example. The computer system mainly includes a processor and a memory as hardware. The function as the control unit 7 in the present disclosure is realized by the processor executing the program recorded in the memory of the computer system. The program may be recorded in advance in a memory of a computer system, may be provided through a telecommunication line, or recorded in a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive that can be read by the computer system. May be provided. A processor of a computer system includes one or more electronic circuits including a semiconductor integrated circuit (IC) or a large scale integrated circuit (LSI). The plurality of electronic circuits may be integrated on one chip, or may be distributed on the plurality of chips. The plurality of chips may be integrated into one device, or may be distributed and provided in a plurality of devices.
また、コンセントシステム10における複数の機能が、1つの筐体4に集約されていることはコンセントシステム10に必須の構成ではなく、コンセントシステム10の構成要素は、複数の筐体に分散して設けられていてもよい。さらに、制御部7等、コンセントシステム10の少なくとも一部の機能は、例えば、クラウド(クラウドコンピューティング)等によって実現されてもよい。反対に、上記実施形態のように、コンセントシステム10の全ての機能が、1つの筐体4に集約されていてもよい。
It is not essential for the outlet system 10 that a plurality of functions in the outlet system 10 are integrated into one casing 4, and the constituent elements of the outlet system 10 are provided in a plurality of casings. It may be done. Furthermore, at least some of the functions of the outlet system 10 such as the control unit 7 may be realized by, for example, cloud (cloud computing). On the contrary, all the functions of the outlet system 10 may be integrated into one housing 4 as in the above embodiment.
また、制御部7は、コンセントシステム10に必須の構成ではなく、適宜省略可能である。つまり、コンセントシステム10は、判定条件を満たしたときに、開閉部6が、導通状態から遮断状態に切り替わるように動作し、判定条件を満たさない場合において、開閉部6が、遮断状態から導通状態に切替可能であればよい。そのため、例えば、温度検出部5の出力(検出信号)が直接的に開閉部6に入力され、開閉部6が検出信号を受けて動作する場合には、制御部7が省略可能である。さらに、例えば、温度検出部5がバイメタル等であって、開閉部6を直接的に駆動する場合においても、制御部7が省略可能である。
Further, the control unit 7 is not an essential component of the outlet system 10 and can be omitted as appropriate. That is, the outlet system 10 operates so that the opening / closing unit 6 switches from the conductive state to the cut-off state when the determination condition is satisfied, and when the determination condition is not satisfied, the open / close unit 6 is switched from the cut-off state to the conductive state. It suffices if it can be switched to. Therefore, for example, when the output (detection signal) of the temperature detection unit 5 is directly input to the opening / closing unit 6 and the opening / closing unit 6 receives the detection signal and operates, the control unit 7 can be omitted. Further, for example, even when the temperature detection unit 5 is bimetal or the like and the opening / closing unit 6 is directly driven, the control unit 7 can be omitted.
また、上記実施形態では、温度検出部5が接続部材3の温度を検出温度として検出し、かつ端子部材2の温度を補助検出温度として検出する場合について説明したが、この例に限らない。例えば、温度検出部5は、端子部材2の温度、又は端子部材2及び接続部材3の両方の温度を検出温度として検出してもよい。端子部材2及び接続部材3の両方の温度を検出温度とする場合において、判定条件は、端子部材2の検出温度と接続部材3の検出温度とで、同一であってもよいし、互いに異なっていてもよい。
Moreover, although the temperature detection part 5 detected the temperature of the connection member 3 as a detection temperature and detected the temperature of the terminal member 2 as an auxiliary detection temperature in the said embodiment, it is not restricted to this example. For example, the temperature detection unit 5 may detect the temperature of the terminal member 2 or the temperatures of both the terminal member 2 and the connection member 3 as detection temperatures. When the temperatures of both the terminal member 2 and the connecting member 3 are set as the detected temperatures, the determination conditions may be the same for the detected temperature of the terminal member 2 and the detected temperature of the connecting member 3, or different from each other. May be.
また、判定条件は、検出温度が閾値温度以上であることを含んでいればよく、検出温度が閾値温度以上であることに加えて、他の条件を含んでいてもよい。例えば、判定条件は、検出温度が閾値温度以上であるという事象が、所定時間継続すること、所定回数発生すること、又は所定値以上の頻度で発生すること等を含んでいてもよい。補助判定条件についても同様に、補助検出温度が補助閾値温度以上であることを含んでいればよく、補助検出温度が補助閾値温度以上であることに加えて、他の条件を含んでいてもよい。注意判定条件についても同様に、検出温度が注意温度以上であることを含んでいればよく、検出温度が注意温度以上であることに加えて、他の条件を含んでいてもよい。
Further, the determination condition only needs to include that the detected temperature is equal to or higher than the threshold temperature, and may include other conditions in addition to the detected temperature being equal to or higher than the threshold temperature. For example, the determination condition may include that the event that the detected temperature is equal to or higher than the threshold temperature continues for a predetermined time, occurs a predetermined number of times, or occurs at a frequency equal to or higher than a predetermined value. Similarly, the auxiliary determination condition only needs to include that the auxiliary detection temperature is equal to or higher than the auxiliary threshold temperature, and may include other conditions in addition to the auxiliary detection temperature being equal to or higher than the auxiliary threshold temperature. . Similarly, the caution determination condition only needs to include that the detected temperature is equal to or higher than the caution temperature, and may include other conditions in addition to the detected temperature being equal to or higher than the caution temperature.
また、コンセント1は、接地極付きに限らず、接地極無しであってもよいし、例えば、交流200V用又は直流用のコンセント(Outlet)であってもよい。さらに、コンセント1は、Aタイプのコンセントに限らず、例えば、Bタイプ又はCタイプのように、ピン形状の栓刃を有するプラグを接続可能なコンセントであってもよい。コンセント1は、2個口タイプに限らず、例えば、1個口タイプ又は3個口タイプであってもよい。さらに、コンセントシステム10は、コンセント1だけでなく、例えば、人感センサ、タイマ又はスイッチ等を更に備えていてもよい。また、端子部材2は、速結端子でなくてもよく、例えば、ねじ式端子であってもよい。また、コンセント1は、取付枠を用いて後部が造営面100内に埋め込まれた状態で設置される構成(埋込設置型)に限らず、全体が露出した状態で造営面100に設置される構成(露出設置型)であってもよい。
Further, the outlet 1 is not limited to having a grounding electrode, and may be without a grounding electrode. For example, the outlet 1 may be an AC 200V outlet or a DC outlet. Furthermore, the outlet 1 is not limited to the A type outlet, and may be an outlet to which a plug having a pin-shaped plug blade, such as a B type or a C type, can be connected. The outlet 1 is not limited to the two-port type, and may be, for example, a one-port type or a three-port type. Furthermore, the outlet system 10 may further include not only the outlet 1 but also a human sensor, a timer, a switch, or the like. Moreover, the terminal member 2 may not be a quick connection terminal, for example, may be a screw-type terminal. In addition, the outlet 1 is not limited to a configuration (embedded installation type) in which the rear portion is embedded in the construction surface 100 using an attachment frame, but is installed on the construction surface 100 in a state where the whole is exposed. A structure (exposed installation type) may be used.
また、コンセント1は、プラグ91の抜け止めとなるロック機構を有していてもよい。ロック機構は、例えば、プラグ91を回転させることによってプラグ91の栓刃911の抜け止めを行う。コンセント1は、扉付きであってもよい。
Further, the outlet 1 may have a lock mechanism that prevents the plug 91 from coming off. For example, the locking mechanism prevents the plug blade 911 of the plug 91 from coming off by rotating the plug 91. The outlet 1 may have a door.
また、上記実施形態では、電磁釈放装置が作動して開閉部6が導通状態から遮断状態に切り替わると、開閉部6に連動して操作部材81もオフ位置に移動するが、この構成に限らない。例えば、開閉部6が導通状態から遮断状態に切り替わる際、操作部材81については、オン位置のままであってもよい。この場合、復旧操作は、操作部材81をオン位置からオフ位置に一旦移動させた後、操作部材81をオフ位置からオン位置に移動させることで実現される。
Further, in the above embodiment, when the electromagnetic release device is operated and the opening / closing part 6 is switched from the conductive state to the cutoff state, the operation member 81 is also moved to the off position in conjunction with the opening / closing part 6, but this is not restrictive. . For example, when the opening / closing part 6 is switched from the conductive state to the cut-off state, the operation member 81 may remain in the on position. In this case, the restoration operation is realized by moving the operation member 81 from the on position to the off position and then moving the operation member 81 from the off position to the on position.
また、開閉部6は、例えば、メカニカルリレー又は半導体スイッチ等で実現されてもよい。
Moreover, the opening / closing part 6 may be realized by, for example, a mechanical relay or a semiconductor switch.
また、温度検出部5は、少なくとも1つの温度センサ51を含んでいればよく、1つの温度センサ51に加えて他の温度センサを1つ以上含んでいてもよい。この場合においても、1つの温度センサ51は、複数の第1検出点と、複数の第2検出点と、の少なくとも一方を含む検出点群P100の温度を、検出温度として検出する。
Further, the temperature detection unit 5 only needs to include at least one temperature sensor 51, and may include one or more other temperature sensors in addition to the one temperature sensor 51. Also in this case, one temperature sensor 51 detects the temperature of the detection point group P100 including at least one of the plurality of first detection points and the plurality of second detection points as the detection temperature.
また、伝熱構造50は、筐体4の内部空間40を埋めるポッティング材に限らず、その他の樹脂部材若しくは金属部材等の伝熱性を有する部材、又はヒートパイプ等であってもよいし、これらの組み合わせで実現されてもよい。この場合、内部空間40を埋めるポッティング材は省略可能である。さらに、伝熱構造50は、端子部材2及び接続部材3の間を電気的に接続する導電部材と一体であってもよい。つまり、導電部材(リード板30及び編組線等)が伝熱構造50として兼用されてもよい。
Further, the heat transfer structure 50 is not limited to the potting material that fills the internal space 40 of the housing 4, and may be a member having heat transfer properties such as another resin member or a metal member, or a heat pipe. It may be realized by a combination of In this case, a potting material filling the internal space 40 can be omitted. Furthermore, the heat transfer structure 50 may be integrated with a conductive member that electrically connects the terminal member 2 and the connection member 3. That is, a conductive member (such as the lead plate 30 and the braided wire) may be used as the heat transfer structure 50.
また、上記実施形態では、状態提示部72での提示の態様は、判定条件を満たす場合でも、補助判定条件を満たす場合でも同じであるが、これに限らず、判定条件を満たす場合と補助判定条件を満たす場合とで、状態提示部72は異なる態様の提示を行ってもよい。一例として、閾値温度Tth2以上と判定された実測温度T1が接続部材3の温度である場合には第1表示灯821を点灯させ、実測温度T1が端子部材2の温度である場合には第1表示灯821を点滅させる等により、表示部82の表示態様を異ならせてもよい。
Moreover, in the said embodiment, although the aspect of the presentation in the state presentation part 72 is the same also when satisfy | filling determination conditions, and when satisfy | filling auxiliary | assistant determination conditions, it is not restricted to this, and when auxiliary | assistant determination conditions are satisfied. The state presenting unit 72 may present a different aspect when the condition is satisfied. As an example, when the measured temperature T1 determined to be equal to or higher than the threshold temperature Tth2 is the temperature of the connecting member 3, the first indicator lamp 821 is turned on, and when the measured temperature T1 is the temperature of the terminal member 2, the first is displayed. The display mode of the display unit 82 may be changed by blinking the indicator lamp 821 or the like.
本開示にて、検出温度と閾値温度等の2値の比較において、「以上」としているところは、2値が等しい場合、及び2値の一方が他方を超えている場合との両方を含む。ただし、これに限らず、ここでいう「以上」は、2値の一方が他方を超えている場合のみを含む「より大きい」と同義であってもよい。つまり、2値が等しい場合を含むか否かは、基準値等の設定次第で任意に変更できるので、「以上」か「より大きい」かに技術上の差異はない。同様に、「未満」においても「以下」と同義であってもよい。
In this disclosure, in the comparison of the binary values such as the detected temperature and the threshold temperature, “more than” includes both the case where the two values are equal and the case where one of the two values exceeds the other. However, the present invention is not limited to this, and “more than” here may be synonymous with “greater than” including only when one of the binary values exceeds the other. That is, whether or not the case where the two values are equal can be arbitrarily changed depending on the setting of the reference value or the like, so there is no technical difference between “greater than” or “greater than”. Similarly, “less than” may be synonymous with “below”.
(実施形態2)
本実施形態に係るコンセントシステム10Aは、図7A及び図7Bに示すように、コンセント1Aが温度センサ52を有する点で、実施形態1に係るコンセントシステム10と相違する。以下、実施形態1と同様の構成については、共通の符号を付して適宜説明を省略する。 (Embodiment 2)
Theoutlet system 10A according to the present embodiment is different from the outlet system 10 according to the first embodiment in that the outlet 1A includes a temperature sensor 52 as illustrated in FIGS. 7A and 7B. Hereinafter, the same configurations as those of the first embodiment are denoted by common reference numerals, and description thereof is omitted as appropriate.
本実施形態に係るコンセントシステム10Aは、図7A及び図7Bに示すように、コンセント1Aが温度センサ52を有する点で、実施形態1に係るコンセントシステム10と相違する。以下、実施形態1と同様の構成については、共通の符号を付して適宜説明を省略する。 (Embodiment 2)
The
すなわち、本実施形態では、温度検出部5は、温度センサ51(以下、「第1の温度センサ51」ともいう)と、温度センサ52(以下、「第2の温度センサ52」ともいう)と、の2つのセンサ素子を有している。第2の温度センサ52は、第1の温度センサ51と同様に、例えば、サーミスタ、熱電対、バイメタル又はサーモパイル等で実現される。
That is, in the present embodiment, the temperature detection unit 5 includes a temperature sensor 51 (hereinafter also referred to as “first temperature sensor 51”) and a temperature sensor 52 (hereinafter also referred to as “second temperature sensor 52”). The two sensor elements are provided. Similar to the first temperature sensor 51, the second temperature sensor 52 is realized by, for example, a thermistor, a thermocouple, a bimetal, a thermopile, or the like.
第1の温度センサ51は、接続部材3の温度を検出するためのセンサである。第2の温度センサ52は、端子部材2の温度を検出するためのセンサである。そのため、第1の温度センサ51は、接続部材3に設けられた検出点P3,P4(図1B参照)と伝熱構造50にて熱的に結合され、第2温度センサ52は、端子部材2に設けられた検出点P1,P2(図1B参照)と伝熱構造50にて熱的に結合されている。
The first temperature sensor 51 is a sensor for detecting the temperature of the connection member 3. The second temperature sensor 52 is a sensor for detecting the temperature of the terminal member 2. Therefore, the first temperature sensor 51 is thermally coupled to the detection points P3 and P4 (see FIG. 1B) provided on the connection member 3 at the heat transfer structure 50, and the second temperature sensor 52 is connected to the terminal member 2. The heat transfer structure 50 is thermally coupled to the detection points P1 and P2 (see FIG. 1B) provided in the heat transfer structure 50.
第2の温度センサ52は、例えば、筐体4の内部空間40(図5A参照)に配置されている。具体的には、第2の温度センサ52は、図7A及び図7Bに示すように、内部空間40のうち、端子ブロック45の後方に配置されている。より詳細には、第2の温度センサ52は、図7Aに示すように、正面視において、互いに異極性となる一対の端子部材2の間に配置されている。
The second temperature sensor 52 is disposed, for example, in the internal space 40 of the housing 4 (see FIG. 5A). Specifically, as shown in FIGS. 7A and 7B, the second temperature sensor 52 is disposed behind the terminal block 45 in the internal space 40. More specifically, as shown in FIG. 7A, the second temperature sensor 52 is disposed between a pair of terminal members 2 having different polarities in front view.
上記構成により、端子部材2に設けられた検出点P1,P2の温度については、第2の温度センサ52で検出可能となる。ここで、検出点P1及び検出点P2は、それぞれ互いに異極性である一対の端子部材2の一方及び他方に設けられた検出点であるため、検出点P1及び検出点P2の組み合わせは、互いに電気的に絶縁された複数の第1検出点となる。つまり、第2の温度センサ52での温度の検出対象となる検出点群は、複数の第1検出点(検出点P1,P2)を含むことになる。一方、接続部材3に設けられた検出点P3,P4の温度については、第1の温度センサ51で検出可能である。ここで、検出点P3及び検出点P4は、それぞれ互いに異極性である一対の接続部材3の一方及び他方に設けられた検出点であるため、検出点P3及び検出点P4の組み合わせは、互いに電気的に絶縁された複数の第1検出点となる。つまり、第1の温度センサ51での温度の検出対象となる検出点群は、複数の第1検出点(検出点P3,P4)を含むことになる。
With the above configuration, the temperature of the detection points P1 and P2 provided on the terminal member 2 can be detected by the second temperature sensor 52. Here, since the detection point P1 and the detection point P2 are detection points provided on one and the other of the pair of terminal members 2 having different polarities, the combination of the detection point P1 and the detection point P2 is mutually electric. The plurality of first detection points are electrically insulated. That is, the detection point group that is the temperature detection target of the second temperature sensor 52 includes a plurality of first detection points (detection points P1, P2). On the other hand, the temperature of the detection points P3 and P4 provided on the connecting member 3 can be detected by the first temperature sensor 51. Here, since the detection point P3 and the detection point P4 are detection points provided on one and the other of the pair of connecting members 3 having different polarities, the combination of the detection point P3 and the detection point P4 is mutually electric. The plurality of first detection points are electrically insulated. In other words, the detection point group that is the temperature detection target of the first temperature sensor 51 includes a plurality of first detection points (detection points P3 and P4).
本実施形態の構成によれば、互いに電気的に絶縁された複数の第1検出点の温度を、1つの温度センサ(51又は52)で検出するので、検出点の数に対して必要な温度センサの個数を少なく抑えることができ、部品点数の増加を抑えることができる。しかも、端子部材2の温度と接続部材3の温度とは、別々の温度センサ51,52で検出されるので、端子部材2の温度と接続部材3の温度とを区別しやすくなる。
According to the configuration of the present embodiment, the temperature of a plurality of first detection points that are electrically insulated from each other is detected by one temperature sensor (51 or 52), so the temperature required for the number of detection points. The number of sensors can be reduced, and the increase in the number of parts can be suppressed. In addition, since the temperature of the terminal member 2 and the temperature of the connecting member 3 are detected by separate temperature sensors 51 and 52, it becomes easy to distinguish the temperature of the terminal member 2 and the temperature of the connecting member 3.
実施形態2で説明した構成は、実施形態1で説明した種々の構成(変形例を含む)と適宜組み合わせて採用可能である。
The configuration described in Embodiment 2 can be used in appropriate combination with the various configurations (including modifications) described in Embodiment 1.

As described above, the outlet system (10, 10A) according to the first aspect includes the terminal member (2), the connection member (3), the housing (4), the temperature detection unit (5), An opening / closing part (6) and a heat transfer structure (50) are provided. The power supply line (92) is connected to the terminal member (2). The plug (91) is connected to the connecting member (3). A housing | casing (4) accommodates a terminal member (2) and a connection member (3). The temperature detector (5) includes one temperature sensor (51 or 52). The temperature detector (5) uses the temperature of the detection point group (P100) including at least one of the plurality of first detection points and the plurality of second detection points as one detection temperature sensor (51 or 52). ) To detect. The plurality of first detection points are detection points that are electrically insulated from each other. The plurality of second detection points are detection points provided in different portions of the terminal member (2), the connection member (3), and the internal space (40) of the housing (4). The opening / closing part (6) is electrically connected between the terminal member (2) and the connection member (3). The opening / closing unit (6) switches from the conductive state to the cut-off state when a determination condition including that the detected temperature is equal to or higher than the threshold temperature is satisfied. The heat transfer structure (50) thermally couples the detection point group (P100) and one temperature sensor (51 or 52).
この態様によれば、互いに電気的に絶縁された複数の第1検出点、及び互いに異なる部位に設けられた複数の第2検出点、の少なくとも一方の温度を、1つの温度センサ(51又は52)が検出する。したがって、1つの温度センサ(51又は52)は、例えば、複数の第1検出点の温度の検出に共用されることになる。または、1つの温度センサ(51又は52)は、例えば、複数の第2検出点の温度の検出に共用されることになる。そのため、複数の第1検出点の各々に個別の温度センサを設ける場合、又は複数の第2検出点の各々に個別の温度センサを設ける場合に比べて、必要な温度センサの個数を少なく抑えることが可能である。結果的に、コンセントシステム(10,10A)によれば、検出点の数に対して必要な温度センサの個数を少なく抑えることができ、部品点数の増加を抑えることができる。
According to this aspect, the temperature of at least one of the plurality of first detection points that are electrically insulated from each other and the plurality of second detection points that are provided at different sites is determined by one temperature sensor (51 or 52). ) Is detected. Therefore, one temperature sensor (51 or 52) is shared for detecting the temperature of a plurality of first detection points, for example. Alternatively, one temperature sensor (51 or 52) is shared for detecting the temperature of a plurality of second detection points, for example. Therefore, the number of necessary temperature sensors can be reduced as compared with the case where individual temperature sensors are provided at each of the plurality of first detection points or when individual temperature sensors are provided at each of the plurality of second detection points. Is possible. As a result, according to the outlet system (10, 10A), the number of temperature sensors required for the number of detection points can be reduced, and an increase in the number of parts can be suppressed.
第2の態様に係るコンセントシステム(10,10A)では、第1の態様において、伝熱構造(50)は、端子部材(2)と接続部材(3)との間を電気的に接続する導電部材とは別体である。
In the outlet system (10, 10A) according to the second aspect, in the first aspect, the heat transfer structure (50) is electrically conductive between the terminal member (2) and the connection member (3). It is a separate body from the member.
この態様によれば、端子部材(2)と接続部材(3)との間の電気的な接続は導電部材で確保されるので、例えば、伝熱構造(50)は導電性を有さなくてもよく、伝熱構造(50)の設計の自由度が向上する。
According to this aspect, since the electrical connection between the terminal member (2) and the connection member (3) is ensured by the conductive member, for example, the heat transfer structure (50) does not have conductivity. In other words, the degree of freedom in designing the heat transfer structure (50) is improved.
第3の態様に係るコンセントシステム(10)では、第1又は2の態様において、温度検出部(5)は、センサ素子として1つの温度センサ(51)のみを有する。
In the outlet system (10) according to the third aspect, in the first or second aspect, the temperature detection unit (5) has only one temperature sensor (51) as a sensor element.
この態様によれば、センサ素子として1つの温度センサ(51)のみが用いられるので、必要な温度センサの個数をより少なく抑えることができ、部品点数の増加を抑えることができる。
According to this aspect, since only one temperature sensor (51) is used as a sensor element, the number of necessary temperature sensors can be suppressed to a smaller level, and an increase in the number of parts can be suppressed.
第2又は3の態様に係る構成については、コンセントシステム(10,10A)に必須の構成ではなく、適宜省略可能である。
The configuration according to the second or third aspect is not a configuration essential to the outlet system (10, 10A) and can be omitted as appropriate.
