The explanation of most preferred embodiment

Below, with reference to the description of drawings embodiments of the invention.

(embodiment 1)

To be a kind of its pattern of expression be the oblique view of inside of the conduction state confirmation signal generator that can insert the socket that has been provided with to Fig. 1, and Fig. 2 is the oblique view of its outward appearance of expression.In Fig. 1 and Fig. 2, housing 1 is made of body 1A and cap 1B, respectively with insulating material moulding such as synthetic resin.On cap 1B, be provided with the fenestra 1a of a break-through, be used to make the head of hereinafter described luminous element 5A and 5B to stretch out, so that can see from the outside.

Be plugged on insertion terminal 2A and 2B in the ambipolar supply socket fixing a pair of mode that can extract with insertion freely on the body 1A.The rearward end of bimetal leaf 4 is fixed in the rearward end of insertion terminal 2A on one side by riveted joint or welding etc., and it is contacted on electricity and heat well.The contact 4a that is installed in bimetal leaf 4 front ends extends to the below of the contact 3a of the fixed engagement device 3 that is fixed on the body 1A.The contact 4a of this bimetal leaf 4, when normal temperature and the contact 3a of connector 3 disconnect, when surpass regulation be higher than the design temperature of normal temperature the time, deform and perk upward, thereby contact with contact 3a is electric.Bimetal leaf 4 is that 2 different metlbonds of the coefficient of expansion are made together,, this conduct produces the device of the temperature movement device use of mechanical displacement but depending on temperature, be not limited to bimetal leaf, also can adopt the shape store alloy of the shape that recovery is being stored in advance under set point of temperature or the same shape store element of making by other materials.Hereinafter, the concrete example that adopts bimetal leaf as the temperature movement device is described.

With head form up for example light-emitting diode (LED) 5A, 5B or bulb etc. are installed on body 1A, its head stretches out from the fenestra 1a of lid 1B, can see from the outside.LED5A, 5B can be luminous with the color that differs from one another, and for example LED5A is blue, and LED5B is red.In housing 1, also installing rectification with diode D and current limliting resistance R.

Fig. 3 is the figure of circuit one example of this signal generator of expression.In this circuit, under the state that bimetal leaf 4 and fixed engagement device 3 disconnect, form from insert terminal 2B by resistance R, diode D and LED5A to the closed circuit that inserts terminal 2A, and LED5A is ignited send blue light.When bimetal leaf 4 contacts with fixed engagement device 3, make electric current also flow through LED5B by them, and make LED5B send red light.

As adopt the signal generator of Fig. 1～3, then in the time will inserting terminal 2A, 2B and insert not shown supply socket, electric current flows through LED5A by resistance R and diode D, and this LED5A is ignited, and sends to be used to conduct electricity the blue light of confirming.Then, when not shown supply socket is risen owing to abnormal temperature takes place for for example overcurrent etc., by inserting terminal 2A the temperature of bimetal leaf 4 is risen, when it surpasses design temperature, bimetal leaf 4 distortion and contacting with fixed engagement device 3 ignites LED5B and sends the red light that is used to report to the police.

As shown in Figure 4, also can use more small-sized chimes of doom generator, for example piezoelectric buzzer 6 or electric bell etc., replace LED5B.In addition, also piezoelectric buzzer 6 chimes of doom generators such as grade and LED5B also can be used simultaneously.

As shown in Figure 5, replace fixed engagement device 3 and the bimetal leaf 4 of Fig. 3, can adopt reed switch 7.In this case, can magnet MG be installed at the leading section of bimetal leaf 4, just often, magnet MG leaves reed switch 7, it is in be failure to actuate (switch disconnection) state, when because the thermal deformation of bimetal leaf 4 when making magnet MG convergence reed switch 7, reed switch 7 is connected, and LED5B is ignited.In the present embodiment, because the make and break contact that may produce spark do not expose, so, can constitute the signal generator of explosion-proof type.

As shown in Figure 6, on body 1A, be provided with another terminal 2C, be installed on the independently union piece that for example teleworking device socket etc. is provided with, if will insert the voltage of terminal 2A guides on the terminal 2C owing to the thermal deformation of bimetal leaf 4, then utilize the voltage that on terminal 2C, produces, can directly or by relay, the time relay will be located at cut-outs such as not shown Inturruptor for sub-line in the power supply unit of socket service voltage or electromagnetic contactors.

Fig. 7 is the figure of the expression variation corresponding with the embodiment of Fig. 3.In device shown in Figure 7, make the direction of each diode among Fig. 3 reverse, simultaneously, the resistance R of Fig. 3 provides with the form that is divided into RA, RB by each LED5A, 5B, in addition, be connected a diode DA between the negative electrode of the anode of LED5B and LED5A, make the cathode side of its negative electrode at LED5A, anode is in the anode-side of LED5B.As adopt the sort circuit structure, and then bimetal leaf 4 was between the normal epoch of off-state, and electric current flows through by resistance R and diode D and is used to conduct electricity the LED5A that confirms, LED5A is ignited and sends blue light.When bimetal leaf 4 became on-state, electric current flow through the LED5B that is used to report to the police by resistance R and diode D, LED5B is ignited and sends red light, and simultaneously, LED5A is extinguished by the effect of diode DA.Present embodiment is characterised in that, by means of the effect of diode DA, LED5A is extinguished.

(embodiment 2)

The conduction state confirmation signal generator of embodiment 2 replaces the contact based on the distortion of bimetal leaf 4 of embodiment 1 to open and close, and utilizes the characteristic variations of the germanium diode that is caused by temperature.Germanium diode itself is that a specific character is easy to the semiconductor device that changes with temperature, and the voltage that makes forward current begin to flow through is about 0.2V when normal temperature, but has along with temperature rises and begin to flow through the character of electric current under low voltage.Therefore, as shown in Figure 8, germanium diode 9 is connected in series by variable resistor VR1 and LED5B.A lead-in wire 9a of germanium diode 9 is directly connected in for example insertion terminal 2A on one side, makes it be easy to conduct the heat that inserts terminal.Present embodiment, dividing circuit is outer basic identical with embodiment 1.Conduction confirms that the LED5A of usefulness, rectification are connected between insertion terminal 2A and the 2B with resistance R1 with diode D1 and current limliting, also by germanium diode 9 and variable resistor VR1 the LED5B and the LED5A of warning usefulness is connected in parallel.

In the circuit of Fig. 8, in the time will inserting terminal 2A, 2B and insert not shown supply socket, if this supply socket is in normal state of temperature, then diode 9 is a high resistance state, make the LED5B can not be luminous, only on the LED5A of conduction affirmation usefulness, flow through electric current, thereby LED5A sends blue light by diode D1 and resistance R 1.When the temperature of supply socket for example raise unusually because of overcurrent etc., its heat also was delivered to germanium diode 9 by lead-in wire 9a from inserting terminal 2A, and its temperature is risen.When the temperature of germanium diode 9 rises to above design temperature, have forward current to flow through LED5B, thereby the LED5B of warning usefulness send red light.Variable resistor VR1 is set, and is in order to carry out such adjustment, promptly to make germanium diode 9 be high resistance state when normal temperature, thereby LED5B is extinguished, and when surpassing design temperature, makes germanium diode 9 energisings, is that LED5B ignites.

Among Fig. 9, insert supply socket and conduction is confirmed the operation that the LED5A of usefulness applies voltage and it is ignited by inserting terminal 2A, 2B, same as described above, but when making germanium diode 9 become conducting state because of the supply socket heating, can the bigger one or more electrical equipment of driving power.For this reason, in the embodiment of Fig. 9, when germanium diode 9 flows through forward current, with transistor T R it is amplified by power amplification.

In the embodiment till Fig. 8, adopting half-wave rectifying circuit based on a diode D, but in the embodiment of Fig. 9, employing be to be used for being single phase bridge type rectifier circu D3 from inserting the full-wave rectifying circuit that alternating electromotive force that terminal 2A, 2B obtain carries out rectification.The dc output end of rectification circuit D3 is connected with filtering capacitor C by current-limiting resistance R2, takes out direct voltage from two terminals P, the N of this capacitor C.Conduction confirms that the LED5A of usefulness is connected between terminals P, the N by resistance R 3.Between terminals P, N, by the light-emitting diode of 2 germanium diode 9A, 9B connection photoelectrical coupler HC that are connected in series, the output of germanium diode 9A, 9B, also the photistor by resistance R 4 and photoelectrical coupler HC is connected with the base stage of transistor T R.Chimes of doom generators such as LED5B, buzzer (Bz) 6, and the solenoid of relay 8 be connected in parallel, and be connected between terminals P, the N by transistor T R.In addition, to the LED5B current-limiting resistance R5 that also is being connected in series.Here,, adopt 2 germanium diode 9A, 9B that are connected in series in order to make the critical point that begins to flow through forward current more remarkable, and with these 2 diodes near inserting terminal 2A or 2B configuration, so that accept the influence of its heat better.

In the circuit of Fig. 9, in the time will inserting terminal 2A or 2B insertion supply socket, conduction confirms that the LED5A of usefulness ignites and send blue light.At this moment, be configured in and insert nearby germanium diode 9A of terminal 2A or 2B, the temperature of 9B does not rise, therefore, when these two diodes were in cut-off state, transistor T R did not flow through base current thereby not conducting.Therefore, LED5B, buzzer 6 and relay 8 are failure to actuate.But when the temperature of supply socket raise, the temperature of germanium diode 9A, 9B was also by inserting terminal 2A, 2B rising and beginning to flow through forward current.When on germanium diode 9A, 9B, flowing through forward current, by photoelectrical coupler HC transistor T R is driven into conducting state, LED5B is ignited, meanwhile, buzzer 6 sends chimes of doom, and makes relay 8 excitations.By the excitation of relay 8, can for example main power circuit be cut off by its contact.Take place at the chimes of doom that does not need to carry out simultaneously the igniting of LED5B, buzzer 6, and the contact of relay 8 situation about opening and closing under, can make its respectively single movement, also can make up etc. and be combined into line operate arbitrarily by LED5B and relay 8 combinations or buzzer 6 and relay 8.

In addition, though germanium diode is a temperature characterisitic semiconductor element the most significantly, the characteristic of other diodes such as silicon changes with heat too, and therefore, this class diode also can be used in the purpose same with germanium diode.In this case, also can install the amplifying circuit that is used for the output amplification of diode.

(embodiment 3)

Figure 10 is that expression is assembled in the oblique view that the carrying spigots number that is installed on supply socket is set up the internal structure of using the conduction state confirmation signal generator in the socket that inserts terminal, and Figure 11 is its outside drawing.In Figure 10,11, jack body 10 adopts the moulding product that are made of insulating material such as synthetic resin that comprise body 10A and cap 10B to make.The surface of cap 10B is by the roof shape portion with plug insertion 10a and have luminous element and form with the par of fenestra 10b.

On body 10A, be set up in parallel with primary side and inserting whole a pair of secondary side union piece 11A, the 11B that constitutes of terminal 12A, 12B, both ends at secondary side union piece 11A, 11B, form twoport connector 11a by V font integral body, be used to insert the insertion terminal 18a of the plug 18 that is installed on the electrical equipment front end.In addition, secondary side union piece 11A on one side, the central portion of its base plate is cut, and with state contact chip 15 is installed with the secondary side union piece 11B of another side insulation at this central portion, when the insertion terminal 18a with plug 18 inserted the secondary side union piece fully, its front end contacted with contact chip 15.

The root of bimetal leaf 14 is fixed on the upper end behind the warpage of contact chip 15 with riveted joint or welding etc., when normal temperature, the leading section of bimetal leaf 14 breaks away from the contact 13a that is fixed on the connector 13 on the body 10A, contacts when temperature rises.On body 10A, also 2 LED5A, 5B as luminous element are installed with luminous head form up.As luminous element, except that LED, neon lamp, glow lamp, bulb etc. also are fit to use.The luminous head of LED5A, 5B is outstanding from the fenestra 10b of cap 10B, makes it can see from the outside, is also installing the diode D and the current limliting resistance R that are connected in series in jack body 10.And bimetal leaf 14 also can be directly fixed on secondary side union piece 11B, in this case, can transfer heat to bimetal leaf 14 quickly.

Contact chip 15 with and insert the secondary side union piece 11A electric insulation that terminal 12A constitutes one, in the time will inserting terminal 18 and insert secondary side union piece 11A fully, the front end that inserts terminal 18a contacts with contact chip 15, and thus connector 13 is connected with secondary side union piece 11A.Like this, present embodiment is except being fixed on bimetal leaf 14 on the contact chip 15 this point, and the circuit of other and Fig. 3 is basic identical.

Inserting the socket number that has been inserted in the not shown supply socket fully at the plug 18 with electrical equipment sets up when using socket, the front end of the insertion terminal 18a of plug 18 contacts with contact chip 15, make contact chip 15 have the current potential that equates with secondary side union piece 11A, thereby make conduction confirm that the LED5A of usefulness ignites and send blue light.When because overcurrent or other reasons make the socket number set up that temperature with socket rises and when making bimetal leaf 14 above design temperature, the leading section of bimetal leaf 14 makes the LED5B of warning usefulness ignite and send red light because of thermal deformation contacts with the contact 13a of connector 13.

(embodiment 5)

Embodiment 5 provides the embodiment with following function, that is, detect when the socket of embodiment 1 and embodiment 2 is set up with the insulating material long term exposure such as synthetic resin of the jack body 10 (Figure 10) of insertion terminal at high temperature with the carrying spigots number of the body 1A (Fig. 1) of the housing 1 of conduction state confirmation signal generator or embodiment 3 carbonization gradually and make its electrical insulating property reduction or the state of destroyed thereby generation leakage current and export electric leakage signal.Therefore, by additional this electric leakage signal output function in the conduction state confirmation signal generator that described in detail so far, can with cause temperature to rise exposing because of overcurrent at high temperature housing 1 or the major break down that electrical insulating property reduces or destruction is caused of jack body 10 resemble the fire prevent in possible trouble.

Figure 14 be in its pattern shown in Figure 1 for inserting the oblique view that has added the socket of above-mentioned electric leakage signal output function in the affirmation signal generator of double-pole socket, Figure 15 is its circuit diagram.Here, the key element identical with Fig. 1 is marked with prosign, and its explanation is omitted.

Be fixed in the substantial middle position between a pair of insertion terminal 2A, the 2B of body 1A of the housing 1 that constitutes by insulating material such as synthetic resin at root, be embedded vertically that the bottom is buried underground and the 2nd bimetal leaf 34 that stretches out the upper end.The form of the composition of this bimetal leaf 34 is to be the approximate vertical attitude when normal temperature, and to be the attitude that leans forward when high temperature.

The rear side of bimetal leaf 34 in housing 1 is that left and right directions is forming not shown guide rail along the direction side by side of inserting terminal 2A, 2B, and moving body 35 is placed on this guide rail in a movable manner.Moving body 35 is made of electrical insulators such as phenolic resins, and the whole engagement projections 35a that forms is installed with travelling contact 36 on front end face on leading flank.This travelling contact 36 is connected with insertion terminal 2A on one side by lead 37, and always pushes fixed contact 38 sides to by spring 39.But, just often, bimetal leaf 34 and engagement projections 35a engagement, thereby the spring force of spring 39 can not work because of bimetal leaf 34.Fixed contact 38 is connected in leakage-current alarm lead-out terminal 41 by current-limiting resistance R6.

In the affirmation signal generator shown in Figure 14 and Figure 15, when insertion terminal 2A, 2B with the confirmation signal generator inserted not shown supply socket, conduction was confirmed to ignite and send blue light with LED5A.When the temperature of supply socket during for example because of abnormal ascending such as overcurrent, its heat is passed to and is inserted terminal 2A and be delivered to bimetal leaf 4.When the temperature of bimetal leaf 4 surpassed design temperature, bimetal leaf 4 distortion made its leading section 4a contact with the contact 3a of connector 3, and warning is ignited with LED5B and sent red light.

More than identical with the effect of embodiment 1, but present embodiment is different with embodiment 1 on the function this point of additional output electric leakage signal as described below.

For example, as the body 1A long term exposure of housing 1 at high temperature, then insulating material such as synthetic resin is with carbonization and electrical insulating property is worsened or destroyed, therefore, between insertion terminal 2A, 2B, flow through leakage current or short circuit current, thereby the temperature of the insulating material of body 1A is risen.Along with this temperature rises, the temperature of the 2nd bimetal leaf 34 also rises, when it surpasses design temperature, its upper end is being out of shape towards the front side to Figure 14 shown in dummy line (2 locking wires), and throw off with the engagement projections 35a of moving body 35 moving body 35 is pushed ahead under the effect of the spring force of spring 39, and travelling contact 36 is crimped on the fixed contact 38.Therefore, the current potential that inserts terminal 2A is guided to leakage-current alarm with on the lead-out terminal 41 by resistance R 6, and can be used as electric leakage signal.

Make not shown relay or actions such as circuit breaker or electromagnetic contactor by this electric leakage signal, thereby, perhaps, can send the warning of light or sound by other warning generation member with dump.

In addition, because moving body 35 is made of insulating material, so electric leakage signal can be taken out and can not make bimetal leaf 34 energisings.

Cap 1B one side that is preferably in housing 1 is provided with not shown resetting device, so that after the distortion by bimetal leaf 34 is moved moving body 35 and is exported electric leakage signal, when bimetal leaf 34 returns to normal temperature, moving body 35 is moved and make the front end of bimetal leaf 34 and engagement projections 35a engagement.

Embodiment shown in Figure 16 has increased the leakage-current alarm display circuit that adopts luminous element on the electric leakage signal output mechanism of Figure 15 device, omitted the conduction confirmation signal here with generating unit and alarm signal generating unit.In Figure 16, be connected by resistance R 9 and diode D8 as the LED5C of luminous element and insert between terminal 2A, the 2B, LED5D and resistance R 8 are being connected in series between the anode of fixed contact 38 and diode D8 simultaneously.In addition, between the negative electrode of fixed contact 38 and LED5C, also connecting a diode D7.The same with the situation of Figure 15, fixed contact 38 is connected with lead-out terminal 41 with leakage-current alarm by resistance R 6.

In the embodiment of Figure 16, just often, only LED5C ignites and sends blue light.When the temperature of the body 1A of housing 1 rose, bimetal leaf 34 distortion and the engagement of engagement projections 35a is thrown off made travelling contact 36 contact with fixed contact 38 by means of the spring force of spring 39.Therefore, LED5C extinguishes, and LED5D ignites and send red light, meanwhile, produces electric leakage signal on lead-out terminal 41.

For fear of whether raising obscure, preferably make LED5C, 5D send the color light different with LED5A, 5B with the temperature of inserting terminal 2A, 2B, or as far as possible with LED5A, 5B separate configuration.

Figure 17 illustrates the major part of the variant embodiment corresponding with the embodiment of Figure 14, Figure 16.Omitted among the figure conduction confirm with and the signal generation of warning usefulness, be the circuit that ignites of LED5A, 5B.Be fixed in a pair of insertion terminal 2A of the body 1A of housing 1, the substantial middle position of 2B at root, be embedded vertically that the bottom is embedded among the body 1A and the bimetal leaf 34 that stretch out the upper end.The form of the composition of this bimetal leaf 34 is, when normal temperature, be the approximate vertical attitude, and when high temperature, be the attitude that leans forward shown in 2 locking wires, the upper end periphery coats with insulating material, and fixed contact 43 is fixed on one side insertion terminal 2A by L font part 44, make its center axis towards device.Leaving on the position of inserting terminal 2A, 2B of body 1A, have the elongated slot 1a of a break-through along the direction side by side of inserting terminal.Be installed in rearward end and have in a movable manner travelling contact 47 on the side with the leading section 46a of the bar 46 of the pilot pin 45 of this elongated slot 1a engagement or roller, contact with fixed contact 43 to connect the mode that disconnects freely.Another side of leading section 46a is when normal temperature and the side of bimetal leaf 34 leading sections engagement.The root of bar 46 is pulled to the lower left of figure by extension spring 48.

When bimetal leaf 34 indeformable normal conditions, the engagement of the front end of the leading section of bimetal leaf 34 and bar 46 is because bar 46 roots make travelling contact 47 contact with fixed contact 43 with the contact pressure of regulation by extension spring 48 tractives.When the electrical insulating property of the body 1A of housing 1 worsens or destroyed and when inserting leakage current between terminal 1A, the 1B temperature of body 1A is risen as mentioned above, to front side distortion, and throw off with the side of the leading section 46a of bar 46 shown in the dummy line among Figure 17 (2 locking wires) upper end of bimetal leaf 34.So, lost the bar 46 of leading section 46a supporting, make the pilot pin 45 that is located at its root in elongated slot 1a, be directed to mobile under the pulling force of extension spring 48, when arriving its terminal part, bar 46 is that the fulcrum counter-clockwise direction is rotated with this terminal part, make of the direction displacement of the leading section of bar, thereby travelling contact 47 and fixed contact 43 are disconnected along arrow Q.

Therefore, can be applied to by bar 46 and go between 49 leakage-current alarms that connecting with on the lead-out terminals 41 with insert the idiostatic signal cut of terminal 2A.So, if the signal when utilizing the voltage signal will be applied on the lead-out terminal 41 to cut off, then could be by relay or directly with power-circuit breaking.

In addition, bimetal leaf 34 is coating not shown insulating material at leading section, so can not be applied on the bimetal leaf 34 with the idiostatic voltage of insertion terminal 2A.Resetting device after electric leakage signal output can also be set on the cap 1B side.

Figure 18 illustrates the embodiment different with the embodiment of Figure 15 to Figure 17.This figure is the same with Figure 16, Figure 17, also omitted conduction confirm with and report to the police with signal generation, be the circuit that ignites of LED5A and LED5B.Between insertion terminal 2A, the 2B of the body 1A that 2 detection of electrical leakage pins 51,52 are embedded at housing 1, its upper end is generally perpendicularly reached near the position of inserting terminal 2A and 2B respectively.For example piezoelectric buzzer 53 as the chimes of doom generator that is used for leakage-current alarm, be connected between the upper end of these 2 detection of electrical leakage pins 51,52 with diode D6 and current-limiting resistance R7 by rectification, in addition, also will be in parallel with this piezoelectric buzzer 53 as for example LED54 of luminous element by resistance R 7.LED54 is arranged to make its luminous head to stretch out also and can see from the outside from the fenestra of the cap 1B of housing 1.Zener diode ZD with Zener voltage corresponding with the rated voltage of piezoelectric buzzer 53 is connected with the outlet side of diode D6.LED54 select with conduction confirm with and the different color of LED5A, 5B of warning usefulness, yellow etc. for example, buzzer 54 is the also selection tone color different with other chimes of doom generators preferably.

In the circuit of Figure 18, so long as the deterioration or the destruction of electrical insulating property are not taken place on the body 1A of housing 1, then LED54 does not ignite, or piezoelectric buzzer 53 does not send and rings.But, as the deterioration or the destruction of electrical insulating property are taken place on body 1A, then produce the voltage of sewing therein on detection of electrical leakage pin 51, and on another detection of electrical leakage pin 52, produce the voltage of sewing from the insertion terminal 2B of another side from insertion terminal 2A on one side.Therefore, LED54 is ignited and send sodium yellow, buzzer 53 sends and rings simultaneously.

As shown in figure 19; as replace Zener diode ZD and with the rectifier diode D6 current regulator diode D7 that is connected in series; even then between detection of electrical leakage pin 51,52, apply near commercial 100V sew voltage the time, also can protect piezoelectric buzzer 53 not to be subjected to the infringement of overcurrent.

As shown in figure 20, current-limiting resistance R8 and diode D6 are connected in series, also can protect piezoelectric buzzer 53 not to be subjected to the infringement of overcurrent.

Chimes of doom generators such as luminous elements such as LED54 and buzzer 53 also not necessarily must both be provided with simultaneously, also can only establish wherein any one.

In addition, as shown in figure 21, at the outlet side connection rectifier diode D5 and the filtering capacitor C1 of 2 detection of electrical leakage pins 51,52, and relay (RY) 55 is in parallel with capacitor C1, thus can make relay 55 excitations by the generation of sewing voltage.The contact output of relay 55 can be exported as electric leakage signal, also can use it for and report to the police or protection.In the present embodiment, for protection relay 55 is not subjected to superpotential infringement, also a Zener diode and relay can be connected in parallel.

As shown in figure 22, if current regulator diode D8 and diode D5 are connected in series, even then between detection of electrical leakage pin 51,52, apply near 100V sew voltage the time, can protection relay 55 be subjected to the infringement of overcurrent yet.

As shown in figure 23, neon lamp 56 is connected between 2 detection of electrical leakage pins 51,52 by current-limiting resistance R9, when voltage is sewed in generation between 2 detection of electrical leakage pins 51,52, also can makes neon lamp 56 is ignited.

At the electric leakage signal output device shown in above-mentioned Figure 15 to Figure 23, be to be additional to socket of the present invention with the device that uses in the conduction state confirmation signal generator, each electric leakage signal output device that structure is different, each signal generator combination in any use that can be extremely shown in Figure 9 with Fig. 3.

Also above-mentioned electric leakage signal output device can be attached to Figure 10 and the carrying spigots number that is plugged in supply socket shown in Figure 11 with the confirmation signal generator sets up with in the socket that inserts terminal.

Equally, also above-mentioned electric leakage signal output device can be attached to Figure 12 and shown in Figure 13 both can being installed in the confirmation signal generator also can be used as on column or the wall etc. in the portable socket that uses.In this case, bimetal leaf 34 and detection of electrical leakage pin 51,52 are arranged between secondary side union piece 21A, the 21B get final product.

Figure 24 and Figure 25 illustrate with example in above-mentioned different electric leakage signal output device is attached to the socket of Figure 12 and band confirmation signal generator shown in Figure 13, be inside oblique view and the outward appearance oblique view that comprises a part of circuit diagram.Among the figure, the member identical with Figure 12, Figure 13 is marked with prosign, its explanation is omitted or is sketched.In addition, in Figure 24, omitted conduction confirmation signal generator.

In Figure 24, Figure 25, a pair of detection of electrical leakage plate 26A, 26B, have a pair of secondary side union piece 21A of clamping part 21a, the centre of 21B at twoport with the two ends in the jack body 20, be separately positioned on position in parallel with each other near secondary side union piece 21A, 21B.Detection of electrical leakage plate 26A, 26B are formed on the コ word shape that two ends have the Japanese of bend 26a, and the upper end intercalation of bend 26a imbedded in the slotted hole 20c with the plug insertion 20a adjacency of cap 20B, the upper surface of bend 26a is flushed substantially with the upper surface of cap 20B.

Shown in the circuit of Figure 24, relay 55 is connected the outlet side of the current rectifying and wave filtering circuit that constitutes by diode D5 and capacitor C1 between detection of electrical leakage plate 26A, the 26B.When jack body 20 become for a certain reason high temperature electrical insulating property around the plug insertion 20a of cap 20B is reduced or destroyed thus on a pair of detection of electrical leakage plate 26A, 26B, produce from secondary side union piece 21A, 21B sew voltage the time, relay 55 excitations, and utilize its contact output as the detection of electrical leakage signal.

As according to Figure 24,25 embodiment, then a pair of insertion terminal 18a, the 18a of the appliance plug 18 in inserting the plug insertion 20a of jack body 20 around pile up broken wadding of cotton yarn or dust etc. and become the dampness of oil-containing and water thus electric insulation is worsened and a pair of insertion terminal 18a, 18a at plug 18 between the electric leakage stream takes place forms before the phenomenon, sew voltage getting close on detection of electrical leakage plate 26A, the 26B of setting to produce, make relay 55 excitations and produce its contact output.As utilize this contact output directly or indirectly with power-circuit breaking, then the fire that due to leakage current road formation phenomenon can be caused is prevented in possible trouble.

The socket that causes because of the overload electric current and the heating of plug 18, the contact site of the insertion terminal 18a of the easiest clamping part 21a that makes secondary side union piece 21A, 21B and plug 18 becomes high temperature.Therefore, when around the plug insertion 20a of cap 20B because of being heated carbonization and electrical insulating property is reduced or when destroyed, be easy to flow through leakage current, thereby voltage is sewed in generation on detection of electrical leakage plate 26A, 26B, as mentioned above, can be by relay 55 with power-circuit breaking.

In Figure 26, when voltage is sewed in generation on detection of electrical leakage plate 26A, 26B, small-sized chimes of doom generators such as piezoelectric buzzer 53 or electric bell are rung, the LED54 that leakage-current alarm is used ignites.Any in chimes of doom generator or the luminous element also can be set.

The relay circuit part of Figure 24 is identical with the relay circuit part of Figure 21, and the leakage-current alarm circuit part of Figure 26 is identical with the leakage-current alarm circuit part of Figure 18, and its explanation is omitted.In addition, also can make the relay circuit part of Figure 24 identical with the relay circuit part of Figure 22.Further, the circuit diagram part that also can make Figure 26 and Figure 19,20 leakage-current alarm circuit part are identical.

Figure 24,26 device also can partly change to circuit diagram the leakage-current alarm circuit at the employing neon lamp 56 shown in the circuit diagram part of Figure 23.

In addition, the electric leakage signal output device of embodiment 5 also not necessarily must be used in combination with the confirmation signal generator, can constitute independently signal output apparatus respectively.

(embodiment 6)

Embodiment 6 inserts terminal socket as the band with the generation of conduction state confirmation signal and circuit function of automatically cutting off that the connection power supply that is used for appliance plug uses.

Figure 27 is the oblique view of inside one example of the above-mentioned socket of expression, and Figure 28 is confirmation signal generating mechanism and the circuit diagram that reaches circuit automatic cutting off table structure.In Figure 27, Figure 28, jack body 60 comprises body 60A and cap 60B, and constitute by insulating material such as synthetic resin, on cap 60B, be provided with 2 not shown break-through fenestras, be used to make the luminous head of hereinafter described LED61A, 61B to stretch out and can see from the outside.

Insert terminal 62A, 62B fixing a pair of primary side that the mode that can extract with insertion freely is plugged in the bipolar system supply socket on the body 60A, the root of bimetal leaf 64 is fixed on one side primary side and inserts substantial middle position between the primary side insertion terminal 62B of terminal 62A and another side, meeting at right angles and extracting direction with the insertion of primary side insertion terminal meets at right angles with the direction side by side of inserting terminal (below, claim " laterally ") to make it.Bimetal leaf 64 have a long engagement stop hole 64a longitudinally on its leading section, and leading section is out of shape and perk upward when temperature rises.

Central portion at body 60A is provided with not shown guide rail, and will be arranged to and can move along this cross slide way with the moving body 63 that insulating material such as synthetic resin constitute.Moving body 63 is adjacency when normal temperature and under the leading section of bimetal leaf 64, and is always pushed to the lower-left side (right side among Figure 28) of Figure 27 by the compression spring 65 between the lug boss 60a that is configured in protuberance 63a and body 60A.

A straight trough 63b is carved with in side at the close front end of moving body 63, and being provided with at the front end of moving body 63 can be along the 1st travelling contact 66 that laterally moves in the width dimensions of this straight trough 63b.The 1st travelling contact 66 always contacts with fixed contact 71 with the contact pressure of regulation under the effect of compression spring 67.Integrally be provided with one in the positive side of the 1st travelling contact 66 and comparing the 2nd little travelling contact 68 of current capacity with it.The 1st travelling contact 66 is connected with insertion terminal 62A on one side by thicker twisted wire 69.

On body 60A, disposing travelling contact 66 respectively and disconnecting the 2nd fixed contact 72 that mode freely contacts with it to connect with the 1st fixed contact 71 and the travelling contact 68 that connection disconnection mode freely contacts with it.The a pair of secondary side union piece 73A, the 73B that are used for plug 78 are being set on body 60A, and with current capacity big joint cover or electric wire secondary side union piece 73A on one side is connected in the 1st fixed contact 71 respectively, the secondary side union piece 73B of another side is connected in the insertion terminal 62B of another side.

Its leading section is being set on body 60A is passing the movably return pin 74 that side plate 60b stretches out.This return pin 74 always is pressed to the contacts side surfaces of the protuberance 63a that makes its rear end and moving body 63 by the spring 65 weak springs 75 of elasticity rate pushing moving body 63.

Vertically be embedded one at the upper surface of moving body 63 and throwing off the engaging pin 76 that the engagement stop hole 64a of freely mode and bimetal leaf 64 meshes with engagement, when the front end that stretches out from body 60A with manual mode pushing return pin 74, make moving body 63 overcome the power of spring 65 and move and when the 1st travelling contact 66 that disconnects is contacted with the 1st fixed contact 71, engaging pin 76 meshes with the engagement stop hole 64a of bimetal leaf 64, and will move 63 engagement stop.Under this state, constitute the normal condition that makes secondary side union piece 73A and primary side insertion terminal 62A conducting, thereby realize function as socket.

In jack body 60, also configuration conduction is confirmed the LED61A that for example sends blue light of usefulness, is that circuitry cuts that secondary circuit ignited and sent red light when being cut off confirms that LED61B, the current-limiting resistance r1 of usefulness and r2, rectification are with diode d1 and d2 at nonconducting state.The connection of these electric components as shown in figure 28.Promptly, LED61A, resistance r1 and diode d1 are connected the 2nd fixed contact 72 and primary side inserts between the terminal 62B, LED61B, resistance r2 and diode d1 are connected primary side and insert between terminal 62A, the 62B, between the negative electrode of the 2nd fixed contact 72 and LED61B, also the mode with common cathode is connecting diode d2.

In Figure 27,28 device, rises and when making bimetal leaf 64 when the temperature of jack body 60 just in case because of overcurrent etc. above design temperature, as among Figure 27 with shown in the illusory line (two-dot chain line), bimetal leaf 64 distortion make the perk upward of its leading section, and engagement stop hole 64a and engaging pin 76 are thrown off, under the effect of the spring force of spring 65, moving body 63 overcome spring 75 spring force and move and make the 1st travelling contact 66 leave the 1st fixed contact 71, cut off thereby primary side inserted between terminal 62A and the secondary side union piece 73A.Then,, then only need to push return pin 74 with manual mode once more, can make primary side insertion terminal 62A and secondary side union piece 73A become conducting state as mentioned above, and recover function as socket if the temperature of bimetal leaf 64 drops to normal temperature.

Below, illustrate in greater detail the effect of this circuit.When being in the normally state that satisfies as the normal function of socket, contact is to 66/71 and 68/72 closure, and the effect by diode d2 does not ignite LED61B, and only sends blue light by LED61A.Make bimetal leaf 64 distortion and make above-mentioned 2 windings point to disconnecting as the temperature rising because of jack body 60, then LED61A extinguishes, and only LED61B ignites and send red light.It is faint voltage to occur by signal generating circuit in order to prevent under the cut state of secondary circuit between secondary side union piece 73A, 73B to 68/72 purpose that the 2nd contact is set.

Figure 29 is that representation is to make appliance plug 78 band that inserts inserts the oblique view of terminal socket inside from laterally (inserting the direction side by side of terminal 62A, 62B), and Figure 30 is that to have form be the oblique view that makes the socket inside of the insertion terminal that appliance plug 78 inserts from the top in expression.This has the plug direction of insertion is that the difference that the band of socket and Figure 27 of two kinds of multi-form insertion terminals inserts terminal socket only is: because of the syndeton of the primary sides insertion terminal 62B of the installation site of secondary side union piece 79A, 79B (Figure 29) or 80A, 80B (Figure 30) different that cause and the 1st fixed contact 71 and another sides different, and return pin 84 has been changed in the interference that causes for the difference of avoiding because of this installation site, because of other are identical, so be marked with prosign and its explanation is omitted.On the upper surface of the protuberance 63a that return pin 84 vertically is embedded at moving body 63.Be provided with on the cap 60B of jack body 60 that the not shown upper end that makes this return pin 84 is passed and the break-through slotted hole of horizontal (moving direction of moving body 63) that stretch out.
