（實施態樣1） （1）概要 此處首先，參照圖1A及圖1B說明依本實施態樣的配線器具系統10之概要。(Implementation Pattern 1) (1) Summary Here, first, the outline of the wiring appliance system 10 according to this embodiment will be described with reference to FIGS. 1A and 1B.

依本實施態樣的配線器具系統10係固定於施工對象物3，並進行對負載4之電力供給及負載4之控制中的至少一者。本發明所謂的「施工對象物」，係指固定配線器具系統10的物體，例如包含牆壁、頂棚或是地板等營建物，或是桌子、架子、或是櫃台等日常用具（包含裝橫材料）等。又，本發明所謂的「負載」，係指由配線器具系統10供給電力，或是由配線器具系統10加以控制的設備（包含設備、裝置及系統），例如包含：照明器具、空調設備、冰箱、換氣扇、資訊處理裝置或是行動終端等。The wiring appliance system 10 according to this embodiment is fixed to the construction object 3, and performs at least one of power supply to the load 4 and control of the load 4. The "construction object" in the present invention refers to the object to which the wiring appliance system 10 is fixed, for example, includes construction objects such as walls, ceilings, or floors, or daily appliances such as tables, shelves, or counters (including horizontal materials) Wait. In addition, the "load" in the present invention refers to equipment (including equipment, devices, and systems) supplied with power from the wiring appliance system 10 or controlled by the wiring appliance system 10, such as lighting appliances, air conditioning equipment, refrigerators , Ventilation fans, information processing devices or mobile terminals, etc.

亦即，配線器具系統10例如係作為插座（Outlet）、開關裝置、調光裝置、人體感測器裝置或是計時裝置等「配線器具」而使用的系統。例如，具有作為插座之功能的配線器具系統10，係在固定於建築物之牆壁等施工對象物3的狀態下使用，其對空調設備等負載4進行電力供給。又，例如，具有作為開關裝置之功能的配線器具系統10，係在固定於建築物之牆壁等施工對象物3的狀態使用，藉由將對於照明器具等負載4的通電加以導通/斷開，而控制負載4。That is, the wiring appliance system 10 is a system used as a "wiring appliance" such as an outlet, a switch device, a dimming device, a human sensor device, or a timing device, for example. For example, a wiring appliance system 10 that functions as a socket is used in a state of being fixed to a construction object 3 such as a wall of a building, and it supplies power to a load 4 such as an air conditioner. Also, for example, the wiring appliance system 10 having a function as a switch device is used in a state of being fixed to a construction object 3 such as a wall of a building, and by turning on/off the energization of the load 4 such as lighting equipment, And control load 4.

如此之配線器具系統10例如使用於設施。在本實施態樣中，配線器具系統10例如例示使用於集合住宅或是獨戶住宅等住宅設施的情況。本發明並不限於此例，配線器具系統10例如亦可使用於：辨公大樓、商店、學校、福利設施、商業設施、主題樂園、醫院、旅館或是工廠等非住宅設施。簡而言之，不論住宅設施、非住宅設施，只要在各式各樣的設施中大量使用作為負載4之設備，便可將配線器具系統10使用於該等設備的電力供給或控制。再者，配線器具系統10並不限於在屋內使用，例如，亦可在公園或是庭園等戶外設施中的特定空間使用。在戶外用途中，配線器具系統10較佳係針對防水性（包含防雨性及防滴性）、及耐候性等滿足既定性能。Such a wiring appliance system 10 is used in facilities, for example. In the present embodiment, the wiring appliance system 10 exemplifies a case where it is used in residential facilities such as a multi-house or a single-family house. The present invention is not limited to this example. The wiring appliance system 10 can also be used in non-residential facilities such as public buildings, shops, schools, welfare facilities, commercial facilities, theme parks, hospitals, hotels, factories, etc. In short, regardless of residential facilities or non-residential facilities, as long as a large number of devices as loads 4 are used in various facilities, the wiring appliance system 10 can be used for power supply or control of these devices. Furthermore, the wiring appliance system 10 is not limited to be used in a house, for example, it can also be used in a specific space in an outdoor facility such as a park or a garden. In outdoor applications, the wiring appliance system 10 preferably satisfies a predetermined performance with respect to water resistance (including rain resistance and drip resistance) and weather resistance.

一般的配線器具在此種設施中，例如，係使用開關盒等安裝構件而固定於牆壁等施工對象物3。又，一般的配線器具包含用於連接配線（電線）的端子，並藉由將迴繞於牆壁（施工對象物3）內的配線連接於端子，而經由配線電性連接於電源或負載4。例如，在如此之配線器具更換等之際，為了伴隨對配線器具之配線的重新連接，需要一定以上的技術，再者，根據國別或是地區等，可能需要特定的資格。因此，在一般的配線器具中，對於其更換等可能要花費工夫。依本實施態樣之配線器具系統10，藉由採用以下構成，可減輕更換配線器具等所費之功夫。In such facilities, general wiring appliances are fixed to construction objects 3 such as walls using mounting members such as switch boxes, for example. In addition, a general wiring appliance includes terminals for connecting wiring (electric wires), and is electrically connected to the power source or load 4 through the wiring by connecting the wiring that is wound around the wall (construction object 3) to the terminal. For example, in the case of such a wiring device replacement, etc., in order to accompany the reconnection of the wiring of the wiring device, a certain level of technology or more is required. Furthermore, depending on the country or region, a specific qualification may be required. Therefore, in general wiring appliances, it may take time and effort to replace them. According to the wiring appliance system 10 of the present embodiment, by adopting the following configuration, it is possible to reduce the time and effort required to replace the wiring appliance.

依本實施態樣的配線器具系統10包含第一單元1及第二單元2。第一單元1係固定於施工對象物3。第二單元2係可取下地裝設於第一單元1。第一單元1包含電力接收部11（參照圖3）及裝設空間12（參照圖1A）。電力接收部11係接收電力供給。裝設空間12係用於裝設一個第二單元2的空間。第二單元2係具有功能部21（參照圖4）的配線器具。功能部21係進行對負載4的電力供給及負載4之控制中的至少一者。第一單元1係供電至第二單元2。The wiring appliance system 10 according to this embodiment includes a first unit 1 and a second unit 2. The first unit 1 is fixed to the construction target 3. The second unit 2 is detachably installed on the first unit 1. The first unit 1 includes a power receiving unit 11 (refer to FIG. 3) and an installation space 12 (refer to FIG. 1A). The power receiving unit 11 receives power supply. The installation space 12 is a space for installing a second unit 2. The second unit 2 is a wiring appliance having a functional unit 21 (refer to FIG. 4). The functional unit 21 performs at least one of power supply to the load 4 and control of the load 4. The first unit 1 supplies power to the second unit 2.

亦即，配線器具系統10藉由採用上述構成，可減輕更換配線器具所費之工夫。簡而言之，由於作為配線器具的第二單元2，係可取下地裝設於固定在施工對象物3的第一單元1，故藉由將第二單元2從第一單元1取下，可僅將第二單元2從施工對象物3取下。此時，由於具備用於接收電力供給之電力接收部11的第一單元1，尚留在施工對象物3側，故即使不進行對電力接收部11之配線51（參照圖2B）的重新連接，亦可更換作為配線器具的第二單元2等。從而，根據配線器具系統10，可減輕更換配線器具等所費之功夫。That is, by adopting the above-mentioned configuration of the wiring appliance system 10, the labor for replacing the wiring appliance can be reduced. In short, since the second unit 2 as a wiring appliance is detachably installed in the first unit 1 fixed to the construction object 3, by removing the second unit 2 from the first unit 1, Only the second unit 2 is removed from the construction target 3. At this time, since the first unit 1 equipped with the power receiving unit 11 for receiving power supply is still on the side of the construction object 3, even if the wiring 51 (see FIG. 2B) of the power receiving unit 11 is not reconnected , Can also replace the second unit 2 as a wiring appliance. Therefore, according to the wiring appliance system 10, it is possible to reduce the time and effort required to replace the wiring appliance.

又，依本實施態樣之單元裝置，係作為第一單元1或是第二單元2而使用於配線器具系統10的裝置。換言之，第一單元1及第二單元2係分別由單元裝置構成。因此，若從整個配線器具系統10來看，作為第二單元2的單元裝置係可取下地裝設於作為第一單元1的單元裝置。Furthermore, the unit device according to this embodiment is a device used in the wiring appliance system 10 as the first unit 1 or the second unit 2. In other words, the first unit 1 and the second unit 2 are respectively constituted by unit devices. Therefore, from the perspective of the entire wiring appliance system 10, the unit device as the second unit 2 is detachably attached to the unit device as the first unit 1.

（2）詳細 以下，參照圖1A~圖4，詳細說明依本實施態樣的配線器具系統10之構成。(2) Details Hereinafter, with reference to FIGS. 1A to 4, the configuration of the wiring appliance system 10 according to this embodiment will be described in detail.

The function unit 21 performs at least one of "power supply to load 4" and "control of load 4". In this embodiment, the second unit 2 has the function of “a socket (outlet) that can be connected to a plug of the load 4”. Therefore, the functional unit 21 is a socket block for supplying power to the load 4. The load 4 has a pair of insert pieces 41 on its plug. The so-called "insertion piece" in the present invention refers to the conductive member of the plug that is inserted into the socket (second unit 2), such as a blade or a plug. In this embodiment, each of the pair of insert pieces 41 is a blade piece composed of a flat metal plate. The pair of insertion pieces 41 are arranged so as to face each other in the thickness direction of each insertion piece 41.

在本實施態樣中，第二單元2具有「作為沒有接地電極之交流100V用，且可連接一個插頭之單口型插座」的功能。具體而言，第二單元2係在前板部23具有一對***孔231。一對***孔231係設置成在第二單元2的前面形成開口。一對***孔231可***插頭的一對***片41。功能部21係在一對***片41***一對***孔231的狀態下，對負載4進行電力供給，並以機械的方式固持插頭。In this embodiment, the second unit 2 has the function of "a single-port socket for AC 100V without a ground electrode and a plug can be connected". Specifically, the second unit 2 has a pair of insertion holes 231 in the front plate portion 23. A pair of insertion holes 231 are provided to form an opening in the front of the second unit 2. A pair of insertion holes 231 can be inserted into a pair of insertion pieces 41 of the plug. The functional part 21 supplies power to the load 4 in a state where the pair of insertion pieces 41 are inserted into the pair of insertion holes 231, and mechanically holds the plug.

此處，第二單元2在裝設至裝設空間12時，係伴隨相對於第一單元1的直線移動。亦即，在將第二單元2裝設至第一單元1時，係如圖1A所示，至少伴隨第二單元2相對於第一單元1的直線移動。再者，第二單元2在裝設至裝設空間12時，伴隨對於第一單元1的相對旋轉。亦即，在將第二單元2裝設至第一單元1時，係如圖1B所示，至少伴隨第二單元2對於第一單元1的相對旋轉。更詳細而言，第二單元2係藉由往箭頭A1（參照圖1A）的方向筆直地***第一單元1後，再相對於第一單元1往箭頭A2（參照圖1B）的方向旋轉，而裝設於第一單元1。此處，在裝設及取下第二單元2時，係使第二單元2往相反方向旋轉。在本實施態樣中，就一例而言，在將第二單元2裝設至第一單元1時，係在前視觀察下將第二單元2往順時針旋轉，在從第一單元1取下第二單元2時，係在前視觀察下將第二單元2往逆時針旋轉。Here, when the second unit 2 is installed in the installation space 12, it is accompanied by linear movement relative to the first unit 1. That is, when installing the second unit 2 to the first unit 1, as shown in FIG. 1A, at least the second unit 2 moves linearly relative to the first unit 1. Furthermore, when the second unit 2 is installed in the installation space 12, it is accompanied by relative rotation with respect to the first unit 1. That is, when the second unit 2 is installed to the first unit 1, as shown in FIG. 1B, at least the relative rotation of the second unit 2 to the first unit 1 is accompanied. In more detail, the second unit 2 is inserted into the first unit 1 straight in the direction of arrow A1 (refer to FIG. 1A), and then rotated in the direction of arrow A2 (refer to FIG. 1B) relative to the first unit 1. And installed in the first unit 1. Here, when the second unit 2 is installed and removed, the second unit 2 is rotated in the opposite direction. In this embodiment, as an example, when installing the second unit 2 to the first unit 1, the second unit 2 is rotated clockwise in front view, and the second unit 2 is removed from the first unit 1. When lowering the second unit 2, rotate the second unit 2 counterclockwise under front view.

在本實施態樣中，第一單元1係採用天花板接線盒，作為用於電性且機械連接第二單元2的構成。具體而言，第一單元1係採用角形的天花板接線盒（參照圖3）作為電力接收部11。藉此，第二單元2中的一對連接端子24（參照圖4），係藉由從前方***電力接收部11，並進一步在前視觀察下往順時針旋轉，而使第二單元2與第一單元1的電力接收部11電性且機械連接。In this embodiment, the first unit 1 adopts a ceiling junction box as a structure for electrically and mechanically connecting the second unit 2. Specifically, the first unit 1 uses an angular ceiling junction box (refer to FIG. 3) as the power receiving unit 11. Thereby, a pair of connecting terminals 24 (refer to FIG. 4) in the second unit 2 is inserted into the power receiving part 11 from the front, and further rotated clockwise under front view, so that the second unit 2 and The power receiving part 11 of the first unit 1 is electrically and mechanically connected.

如以上所說明，依本實施態樣的配線器具系統10係分割成第一單元1及第二單元2兩個單元。因此，配線器具系統10係以「將其第一單元1固定於施工對象物3，並將其第二單元2裝設於第一單元1」的方式，而整體裝設於施工對象物3。又，如圖2A及圖2B所示，在將整個配線器具系統10裝設於施工對象物3的狀態下，第一單元1係理所當然地嵌入於施工對象物3，而第二單元2的圓形部22，亦通過施工孔33嵌入於施工對象物3。此時，第二單元2的前板部23會從前方覆蓋住施工孔33，藉此封閉施工孔33。As explained above, the wiring appliance system 10 according to this embodiment is divided into two units, the first unit 1 and the second unit 2. Therefore, the wiring appliance system 10 is integrally installed on the construction target 3 in a manner of "fixing its first unit 1 to the construction target 3 and mounting its second unit 2 to the first unit 1". In addition, as shown in FIGS. 2A and 2B, in a state where the entire wiring appliance system 10 is installed on the construction object 3, the first unit 1 is naturally embedded in the construction object 3, and the circle of the second unit 2 The shaped part 22 is also inserted into the construction object 3 through the construction hole 33. At this time, the front plate portion 23 of the second unit 2 covers the construction hole 33 from the front, thereby closing the construction hole 33.

又，在將整個配線器具系統10裝設於施工對象物3的狀態下，第一單元1的前面，係從後方與牆板31中的施工孔33之周邊接觸。再者，第二單元2的前板部23之背面（後面），係從前方與牆板31中的施工孔33之周邊接觸。因此，配線器具系統10係在將牆板31夾在第一單元1的一部分與第二單元2的一部分（前板部23）之間的狀態下，裝設於施工對象物3。再者，配線器具系統10從牆板31之表面起算的突出量，係略等於前板部23的厚度尺寸。In addition, in a state where the entire wiring appliance system 10 is installed on the construction object 3, the front of the first unit 1 is in contact with the periphery of the construction hole 33 in the wall panel 31 from the rear. Furthermore, the back (rear) of the front panel 23 of the second unit 2 is in contact with the periphery of the construction hole 33 in the wall panel 31 from the front. Therefore, the wiring appliance system 10 is installed on the construction target 3 in a state where the wall panel 31 is sandwiched between a part of the first unit 1 and a part of the second unit 2 (the front panel part 23). Furthermore, the amount of protrusion of the wiring appliance system 10 from the surface of the wall panel 31 is approximately equal to the thickness of the front panel 23.

（2.3）第一單元的構成 接著，參照圖3而更詳細地說明第一單元1之構成。(2.3) The composition of the first unit Next, the structure of the first unit 1 will be described in more detail with reference to FIG. 3.

如圖3所示，第一單元1包含：電力接收部11、開關盒13、內蓋體14及***引導部15。亦即，在本實施態樣中，第一單元1除了上述電力接收部11、裝設空間12及開關盒13之外，更包含內蓋體14及***引導部15。As shown in FIG. 3, the first unit 1 includes a power receiving part 11, a switch box 13, an inner cover 14 and an insertion guide part 15. That is, in this embodiment, the first unit 1 includes an inner cover 14 and an insertion guide 15 in addition to the above-mentioned power receiving unit 11, installation space 12 and switch box 13.

如上所述，電力接收部11係角形的天花板接線盒。在本實施態樣中，就一例而言，電力接收部11在前視觀察下，係形成為左右方向長於上下方向的長方體狀。電力接收部11係在背面側具有用於連接配線51（參照圖2B）的端子。As described above, the power receiving unit 11 is an angular ceiling junction box. In this embodiment, as an example, the power receiving unit 11 is formed in a rectangular parallelepiped shape that is longer in the left-right direction than the up-down direction in front view. The power receiving unit 11 has a terminal for connecting the wiring 51 (see FIG. 2B) on the back side.

再者，電力接收部11具有一對連接口111。一對連接口111係位於電力接收部11前面之左右方向的兩端部。一對連接口111各自形成為「沿著以電力接收部11前面之中心點為中心之虛擬圓的弧狀」。此處，一對連接口111各自在繞著電力接收部11前面之中心點的周向之一端部，具有比其他部位寬的寬幅部。因此，第二單元2中的一對連接端子24，係從寬幅部***一對連接口111，並使第二單元2在前視觀察下往順時針旋轉，藉此將第二單元2與電力接收部11電性且機械連接。藉此，第二單元2係經由電力接收部11與配線51電性連接，而使第一單元1可對第二單元2供電。Furthermore, the power receiving unit 11 has a pair of connection ports 111. The pair of connection ports 111 are located at both ends in the left-right direction in front of the power receiving unit 11. Each of the pair of connection ports 111 is formed in an "arc shape along a virtual circle centered on the center point of the front face of the power receiving portion 11". Here, each of the pair of connection ports 111 has a wide portion that is wider than the other portions at one end portion in the circumferential direction around the center point of the front of the power receiving portion 11. Therefore, the pair of connecting terminals 24 in the second unit 2 is inserted into the pair of connecting ports 111 from the wide portion, and the second unit 2 is rotated clockwise in front view, thereby connecting the second unit 2 with The power receiving unit 11 is electrically and mechanically connected. Thereby, the second unit 2 is electrically connected to the wiring 51 via the power receiving portion 11, so that the first unit 1 can supply power to the second unit 2.

在本實施態樣中，電力接收部11係使用一對螺栓161及一對軸環162，而固定於開關盒13。一對螺栓161及一對軸環162，係通過電力接收部11的一對穿通孔112及開關盒13的一對穿通孔132，而在夾住電力接收部11及開關盒13的狀態下，互相扣接。嚴謹而言，一對軸環162係在***一對穿通孔112的狀態下，固定於電力接收部11。一對穿通孔112係在前後方向上貫穿電力接收部11，一對穿通孔132係在前後方向上貫穿開關盒13的底板。藉此，電力接收部11係固定於開關盒13的底板。In this embodiment, the power receiving unit 11 is fixed to the switch box 13 by using a pair of bolts 161 and a pair of collars 162. A pair of bolts 161 and a pair of collars 162 pass through a pair of through holes 112 of the power receiving part 11 and a pair of through holes 132 of the switch box 13, and in a state where the power receiving part 11 and the switch box 13 are clamped, Buckle each other. Strictly speaking, the pair of collars 162 are fixed to the power receiving portion 11 in a state of being inserted into the pair of through holes 112. A pair of through holes 112 penetrate the power receiving portion 11 in the front-rear direction, and a pair of through holes 132 penetrate the bottom plate of the switch box 13 in the front-rear direction. Thereby, the power receiving unit 11 is fixed to the bottom plate of the switch box 13.

開關盒13係形成為前面形成有開口的箱狀。在本實施態樣中，就一例而言，開關盒13為金屬製，並且在前視觀察下形成為略正方形。開關盒13係在開關盒13之底板（後壁）的中央部，具有作為引入部131的孔。從而，開關盒13可通過引入部131，而將配線51從背面（後面）側引入開關盒13內。引入開關盒13內的配線51，係在開關盒13內與電力接收部11電性連接。在開關盒13底板中之引入部131的左右方向兩側，係形成有一對穿通孔132。The switch box 13 is formed in a box shape with an opening formed on the front surface. In this embodiment, as an example, the switch box 13 is made of metal and is formed in a substantially square shape in front view. The switch box 13 is located at the center of the bottom plate (rear wall) of the switch box 13 and has a hole as an introduction portion 131. Therefore, the switch box 13 can be introduced into the switch box 13 from the back (rear) side through the lead-in portion 131. The wiring 51 introduced into the switch box 13 is electrically connected to the power receiving part 11 in the switch box 13. A pair of through holes 132 are formed on both sides of the introduction part 131 in the bottom plate of the switch box 13 in the left-right direction.

在開關盒13的左側壁部中，係形成有用於將開關盒13固定於施工對象物3的一對固定用孔133。亦即，開關盒13係藉由將木螺絲等固定具34（參照圖1A）通過一對固定用孔133並鎖緊於施工對象物3的柱32，而固定於施工對象物3。在開關盒13的右側壁部中，係在與一對固定用孔133相向的位置形成有一對操作用孔134。藉此，可通過各操作用孔134而以螺絲起子等工具操作木螺絲等固定具34。A pair of fixing holes 133 for fixing the switch box 13 to the construction target 3 are formed in the left side wall of the switch box 13. That is, the switch box 13 is fixed to the construction object 3 by passing a fixing tool 34 (see FIG. 1A) such as wood screws through a pair of fixing holes 133 and locking it to the column 32 of the construction object 3. On the right side wall of the switch box 13, a pair of operation holes 134 are formed at positions facing the pair of fixing holes 133. Thereby, the fixture 34, such as a wood screw, can be operated with a tool, such as a screwdriver, through each hole 134 for operation.

內蓋體14係收納於開關盒13內，並作為電力接收部11的蓋體而發揮功能。在本實施態樣中，就一例而言，內蓋體14為樹脂製，並且在前視觀察下形成為略正方形。在前視觀察下，內蓋體14的外周緣係與開關盒13之周壁的內周緣大略一致。因此，在內蓋體14收納於開關盒13的狀態下，內蓋體14係嵌入開關盒13，而至少限制內蓋體14相對於開關盒13往與前後方向垂直的方向移動。內蓋體14係以從前方覆蓋住電力接收部11的方式，組合於開關盒13。藉此，電力接收部11係被收納於開關盒13的底板與內蓋體14之間。The inner lid 14 is housed in the switch box 13 and functions as a lid of the power receiving unit 11. In this embodiment, as an example, the inner cover 14 is made of resin and is formed in a substantially square shape in front view. In front view, the outer periphery of the inner cover 14 is roughly the same as the inner periphery of the peripheral wall of the switch box 13. Therefore, in a state where the inner cover 14 is housed in the switch box 13, the inner cover 14 is fitted into the switch box 13 to at least restrict the inner cover 14 from moving relative to the switch box 13 in a direction perpendicular to the front and back direction. The inner cover 14 is combined with the switch box 13 to cover the power receiving portion 11 from the front. Thereby, the power receiving unit 11 is housed between the bottom plate of the switch box 13 and the inner cover 14.

在本實施態樣中，於內蓋體14的背面（後面）側形成有凹處，並將電力接收部11收納於此凹處內。亦即，以使電力接收部11的至少一部分從內蓋體14的背面進入內蓋體14內的方式，將內蓋體14與電力接收部11加以組合。藉此，可將內蓋體14配置於開關盒13的底板附近。在本實施態樣中，內蓋體14係在開關盒13的內部空間，配置於比前後方向上的中心更底板側（亦即後側）。In this embodiment, a recess is formed on the back (rear) side of the inner cover 14 and the power receiving portion 11 is accommodated in the recess. That is, the inner cover 14 and the power receiving unit 11 are combined so that at least a part of the power receiving unit 11 enters the inner cover 14 from the back surface of the inner cover 14. Thereby, the inner cover 14 can be arranged near the bottom plate of the switch box 13. In this embodiment, the inner cover 14 is located in the internal space of the switch box 13 and is arranged on the side of the bottom plate (that is, the rear side) than the center in the front-rear direction.

此處，在內蓋體14形成有凹部141。凹部141係形成為內蓋體14之前面的一部分往後方凹陷的形狀，藉此朝前方開放。在本實施態樣中，就一例而言，凹部141在前視觀察下係形成為比施工孔33小一圈的圓形（參照圖2A）。凹部141的內徑係大於第二單元2中之圓形部22的外徑，而實際上與圓形部22的外徑大略相同。Here, a recess 141 is formed in the inner cover 14. The recess 141 is formed in a shape in which a part of the front surface of the inner cover 14 is recessed to the rear, thereby opening to the front. In this embodiment, as an example, the recess 141 is formed in a circular shape that is slightly smaller than the construction hole 33 in front view (refer to FIG. 2A ). The inner diameter of the concave portion 141 is larger than the outer diameter of the circular portion 22 in the second unit 2, but in fact it is substantially the same as the outer diameter of the circular portion 22.

再者，內蓋體14包含一對貫穿孔142，形成於與電力接收部11之一對連接口111對應的位置且形成為與電力接收部11之一對連接口111對應的形狀。一對貫穿孔142係在凹部141的底面形成開口，並在厚度方向（前後方向）上貫穿內蓋體14。具體而言，一對貫穿孔142係在前視觀察下，形成於與一對連接口111相同的位置且形成為與一對連接口111相同的形狀，而與電力接收部11的一對連接口111重疊。因此，在將第二單元2裝設於裝設空間12時，第二單元2中的一對連接端子24係通過一對貫穿孔142，而***一對連接口111。又，在一對連接端子24通過一對貫穿孔142而***一對連接口111的狀態下，使第二單元2在前視觀察下往順時針旋轉，藉此，將第二單元2與電力接收部11電性且機械連接。Furthermore, the inner cover 14 includes a pair of through holes 142 formed at positions corresponding to the pair of connection ports 111 of the power receiving portion 11 and formed in a shape corresponding to the pair of connection ports 111 of the power receiving portion 11. A pair of through holes 142 are formed in the bottom surface of the recess 141 and penetrate the inner cover 14 in the thickness direction (front-rear direction). Specifically, the pair of through holes 142 are formed in the same position as the pair of connection ports 111 in front view, and are formed in the same shape as the pair of connection ports 111, and are connected to a pair of the power receiving portion 11 The interface 111 overlaps. Therefore, when the second unit 2 is installed in the installation space 12, the pair of connection terminals 24 in the second unit 2 are inserted into the pair of connection ports 111 through the pair of through holes 142. Also, in a state where the pair of connection terminals 24 are inserted into the pair of connection ports 111 through the pair of through holes 142, the second unit 2 is rotated clockwise in front view, thereby connecting the second unit 2 with the power The receiving part 11 is electrically and mechanically connected.

***引導部15係裝設於開關盒13的前端部，並在對第一單元1裝設（或是取下）第二單元2時，作為限定第二單元2之移動方向的引導部而發揮功能。在本實施態樣中，就一例而言，***引導部15為樹脂製，並且在前視觀察下形成為略正方形。除了***引導部15的前端部以外，在前視觀察下，***引導部15的外周緣係與開關盒13之周壁的內周緣大略一致。再者，***引導部15的前端部在前視觀察下，係比開關盒13的開口面稍微較大地形成。因此，***引導部15會以從前方嵌入的方式裝設於開關盒13之前端部，而至少限制***引導部15相對於開關盒13往與前後方向垂直的方向移動。The insertion guide 15 is installed at the front end of the switch box 13, and functions as a guide for limiting the movement direction of the second unit 2 when the second unit 2 is installed (or removed) to the first unit 1 Features. In this embodiment, as an example, the insertion guide 15 is made of resin, and is formed in a substantially square shape in front view. Except for the front end of the insertion guide 15, the outer periphery of the insertion guide 15 is approximately the same as the inner periphery of the peripheral wall of the switch box 13 in front view. In addition, the front end of the insertion guide 15 is formed slightly larger than the opening surface of the switch box 13 in front view. Therefore, the insertion guide 15 is installed at the front end of the switch box 13 in a manner of being inserted from the front, and at least the insertion guide 15 is restricted from moving relative to the switch box 13 in a direction perpendicular to the front-rear direction.

此處，在***引導部15中，係形成有在厚度方向（前後方向）上貫穿***引導部15的引導孔151。此處，引導孔151係在前視觀察下，形成於***引導部15的大部分而僅殘留***引導部15的外周部，以使***引導部15成為框體。Here, the insertion guide 15 is formed with a guide hole 151 penetrating the insertion guide 15 in the thickness direction (front-rear direction). Here, the guide hole 151 is formed in most of the insertion guide part 15 in front view, and only the outer peripheral part of the insertion guide part 15 remains, so that the insertion guide part 15 becomes a frame.

本實施態樣中，就一例而言，引導孔151係在前視觀察下，為了與凹部141重疊，而形成於和凹部141相同的位置。再者，引導孔151在前視觀察下，係以和凹部141相同的圓形為基準，僅周向的一部分，形成為和凹部141相比，較為擴大的形狀（參照圖2A）。引導孔151的內徑（最小內徑）係與凹部141的內徑相同。亦即，引導孔151的內徑（最小內徑）係大於第二單元2中的圓形部22之外徑，而實際上與圓形部22的外徑大致相同。因此，引導孔151的內周面在前視觀察下，會在複數位置（在圖2A的例子中為八個位置）與凹部141的內周面重疊。In this embodiment, as an example, the guide hole 151 is formed in the same position as the recess 141 in order to overlap the recess 141 in front view. In addition, in front view, the guide hole 151 is based on the same circle as the recess 141, and only a part of the circumferential direction is formed in a shape that is larger than the recess 141 (see FIG. 2A). The inner diameter (minimum inner diameter) of the guide hole 151 is the same as the inner diameter of the recess 141. That is, the inner diameter (minimum inner diameter) of the guide hole 151 is larger than the outer diameter of the circular portion 22 in the second unit 2, but in fact it is substantially the same as the outer diameter of the circular portion 22. Therefore, the inner circumferential surface of the guide hole 151 overlaps the inner circumferential surface of the recess 141 at a plurality of positions (eight positions in the example of FIG. 2A) when viewed from the front.

藉由將如以上說明之構成的電力接收部11、開關盒13、內蓋體14及***引導部15加以組合，而構成第一單元1。又，在將第二單元2裝設於第一單元1的狀態下，第二單元2的圓形部22會通過***引導部15的引導孔151，而***內蓋體14的凹部141內。因此，***引導部15的引導孔151及內蓋體14的凹部141，係分別構成收納第二單元2之凹部121（參照圖1A）的一部分。因此，***引導部15的引導孔151及內蓋體14的凹部141，係包含在裝設空間12中。凹部141的底面，係構成形成於裝設空間12之凹部121的底面。The first unit 1 is formed by combining the power receiving unit 11, the switch box 13, the inner cover 14, and the insertion guide 15 constructed as described above. In addition, when the second unit 2 is installed in the first unit 1, the round portion 22 of the second unit 2 passes through the guide hole 151 of the insertion guide portion 15 and is inserted into the recess 141 of the inner cover 14. Therefore, the guide hole 151 of the insertion guide 15 and the recess 141 of the inner cover 14 each constitute a part of the recess 121 (see FIG. 1A) that houses the second unit 2. Therefore, the guide hole 151 of the insertion guide 15 and the recess 141 of the inner cover 14 are included in the installation space 12. The bottom surface of the recess 141 constitutes the bottom surface of the recess 121 formed in the installation space 12.

又，***引導部15中的引導孔151之內周面、及內蓋體14中的凹部141之內周面，會與第二單元2的圓形部22之外周面接觸，藉此，***引導部15及內蓋體14會限制第二單元2的移動方向。亦即，藉由***引導部15及內蓋體14，可限制第二單元2相對於第一單元1往與前後方向垂直的方向移動。In addition, the inner peripheral surface of the guide hole 151 in the insertion guide portion 15 and the inner peripheral surface of the recess 141 in the inner cover 14 contact the outer peripheral surface of the circular portion 22 of the second unit 2, thereby inserting The guide portion 15 and the inner cover 14 restrict the movement direction of the second unit 2. That is, by inserting the guide portion 15 and the inner cover 14, the second unit 2 can be restricted from moving in a direction perpendicular to the front-rear direction relative to the first unit 1.

從而，在對裝設空間12（凹部121）插拔第二單元2時，***引導部15及內蓋體14係作為引導部而發揮功能，並限制第二單元2往前後方向以外的方向移動。其結果，伴隨第二單元2往前後方向之移動，第二單元2的裝設（或是取下）會變得比較容易。又，在使第二單元2對於第一單元1相對地旋轉時，***引導部15及內蓋體14亦作為引導部而發揮功能，並限制第二單元2之旋轉以外的第二單元2之移動。其結果，伴隨第二單元2的旋轉，第二單元2的裝設（或是取下）會變得比較容易。Therefore, when the second unit 2 is inserted into and removed from the installation space 12 (recess 121), the insertion guide 15 and the inner cover 14 function as guides and restrict the movement of the second unit 2 in directions other than the front-rear direction . As a result, with the movement of the second unit 2 in the front and rear directions, the installation (or removal) of the second unit 2 becomes easier. Moreover, when the second unit 2 is relatively rotated with respect to the first unit 1, the insertion guide 15 and the inner cover 14 also function as guides, and restrict the rotation of the second unit 2 other than the second unit 2. mobile. As a result, as the second unit 2 rotates, the installation (or removal) of the second unit 2 becomes easier.

（2.4）第二單元之構成 接著，參照圖4而更詳細說明第二單元2之構成。(2.4) The composition of the second unit Next, the structure of the second unit 2 will be described in more detail with reference to FIG. 4.

如圖4所示，第二單元2包含：功能部21、圓形部22、前板部23、一對連接端子24及安裝蓋體27。亦即，在本實施態樣中，第二單元2除了上述功能部21、圓形部22、前板部23及一對連接端子24之外，更包含安裝蓋體27。As shown in FIG. 4, the second unit 2 includes: a functional part 21, a circular part 22, a front plate part 23, a pair of connecting terminals 24 and a mounting cover 27. That is, in this embodiment, the second unit 2 further includes a mounting cover 27 in addition to the functional portion 21, the circular portion 22, the front plate portion 23, and the pair of connection terminals 24 described above.

如上述般，功能部21係進行對負載4之電力供給的插座（Outlet）塊。在本實施態樣中，就一例而言，功能部21係固定於「根據日本工業標準而標準化之大角形連用配線器具之安裝框」的嵌入形配線器具。具體而言，功能部21在前視觀察下，係形成為左右方向長於上下方向的長方體狀。功能部21係在背面側具有用於連接電線的端子。與一對連接端子24連接之電線，係與功能部21的端子連接。As described above, the functional unit 21 is an outlet block for supplying power to the load 4. In the present embodiment, as an example, the functional part 21 is fixed to the embedded wiring device of "the mounting frame of the large-angle connecting wiring device standardized in accordance with the Japanese Industrial Standards". Specifically, the functional part 21 is formed in a rectangular parallelepiped shape that is longer in the left-right direction than the up-down direction in front view. The functional part 21 has terminals for connecting electric wires on the back side. The electric wires connected to the pair of connecting terminals 24 are connected to the terminals of the functional part 21.

再者，功能部21具有一對***口211。一對***口211係配置成在功能部21的前面，於左右方向上彼此相向。一對***口211可***負載4之插頭的一對***片41。功能部21係在一對***片41***一對***口211的狀態下，對負載4進行電力供給，且以機械的方式固持插頭。Furthermore, the functional part 21 has a pair of insertion ports 211. The pair of insertion ports 211 are arranged in front of the functional part 21 and face each other in the left-right direction. The pair of insertion ports 211 can be inserted into a pair of insertion pieces 41 of the plug of the load 4. The functional unit 21 supplies power to the load 4 in a state where the pair of insertion pieces 41 are inserted into the pair of insertion openings 211, and mechanically holds the plug.

更詳細而言，功能部21例如具有尿素樹脂或是ASA（Acrylate Styrene Acrylonitrile：丙烯腈-苯乙烯-丙烯酸酯）樹脂等樹脂製的殼體212，並在此殼體212的前面形成有一對***口211。功能部21係在殼體212內之與一對***口211對應的位置，具有一對導電構件。各導電構件係具有導電性及彈性的金屬板，例如以銅或是銅合金等金屬板構成。導電構件係將******口211的***片41以機械的方式固持，並且與***片41電性連接。在本實施態樣中，由於***片41為刃片，故導電構件係夾住而固持***片41的刃片承受構件。In more detail, the functional part 21 has, for example, a housing 212 made of resin such as urea resin or ASA (Acrylate Styrene Acrylonitrile: acrylonitrile-styrene-acrylate) resin, and a pair of inserts is formed on the front of the housing 212口211. The functional portion 21 is located in the housing 212 at a position corresponding to the pair of insertion ports 211, and has a pair of conductive members. Each conductive member is a metal plate having conductivity and elasticity, for example, is made of a metal plate such as copper or copper alloy. The conductive member mechanically holds the insertion piece 41 inserted into the insertion port 211 and is electrically connected to the insertion piece 41. In this embodiment, since the insert piece 41 is a blade piece, the conductive member clamps and holds the blade piece receiving member of the insert piece 41.

又，功能部21更包含從殼體212之左右方向的兩端面突出的複數安裝片213。該等複數安裝片213係在將功能部21固定於「根據日本工業標準而標準化之大角形連用配線器具之安裝框」時使用。在本實施態樣中，係藉由使用該等複數安裝片213，而實現將功能部21固定於圓形部22。In addition, the functional part 21 further includes a plurality of attachment pieces 213 protruding from both end surfaces in the left-right direction of the housing 212. The plural mounting pieces 213 are used when fixing the functional part 21 to the "mounting frame of a large-angle connecting wiring appliance standardized according to Japanese Industrial Standards". In this embodiment, the functional part 21 is fixed to the circular part 22 by using these plural mounting pieces 213.

圓形部22包含中空部25及蓋體26。中空部25在前視觀察下呈圓形，並形成為圓筒狀。蓋體26在前視觀察下呈圓形，並形成為圓盤狀。蓋體26係與中空部25結合，而封閉中空部25的背面（後面）。藉由這般將蓋體26組合至中空部25，而構成圓形部22。在本實施態樣中，就一例而言，構成圓形部22的中空部25及蓋體26，均為樹脂製。The circular portion 22 includes a hollow portion 25 and a cover 26. The hollow portion 25 has a circular shape in front view and is formed in a cylindrical shape. The cover body 26 has a circular shape in front view and is formed in a disc shape. The cover body 26 is combined with the hollow part 25 to close the back (rear) of the hollow part 25. By assembling the cover body 26 to the hollow portion 25 in this way, the circular portion 22 is formed. In this embodiment, as an example, both the hollow portion 25 and the lid body 26 constituting the circular portion 22 are made of resin.

中空部25包含一對螺孔251，用於將蓋體26及安裝蓋體27固定於中空部25。具體而言，蓋體26係藉由從後方***一對螺孔251的一對螺絲281，而與中空部25結合。安裝蓋體27係藉由從前方***一對螺孔251的一對螺絲282，而與中空部25結合。The hollow part 25 includes a pair of screw holes 251 for fixing the cover 26 and the mounting cover 27 to the hollow part 25. Specifically, the cover body 26 is coupled to the hollow portion 25 by a pair of screws 281 inserted into a pair of screw holes 251 from the rear. The mounting cover 27 is combined with the hollow portion 25 by a pair of screws 282 inserted into a pair of screw holes 251 from the front.

又，中空部25係在其內部空間收納功能部21的至少一部分。中空部25更包含用於固定功能部21的一對固定部252。一對固定部252係從中空部25的內周面中，於左右方向上彼此相向的位置，往互相靠近的方向突出。各固定部252具有在上下方向上並列之一對固定凹部253。各固定凹部253係朝前方開放。In addition, the hollow portion 25 accommodates at least a part of the functional portion 21 in its internal space. The hollow portion 25 further includes a pair of fixing portions 252 for fixing the functional portion 21. The pair of fixing portions 252 protrude from positions facing each other in the left-right direction from the inner peripheral surface of the hollow portion 25 in directions approaching each other. Each fixing portion 252 has a pair of fixing recesses 253 arranged in the vertical direction. Each fixing recess 253 is opened to the front.

又，中空部25更包含用於固定前板部23的一對穿通孔254。各穿通孔254係在其厚度方向（徑向）上貫穿中空部25。具體而言，前板部23係藉由從側方***一對穿通孔254的一對螺絲284，而與中空部25結合。此時，一對螺絲284係鎖緊於從前板部23之背面（後面）往後方突出的一對凸片。In addition, the hollow portion 25 further includes a pair of through holes 254 for fixing the front plate portion 23. Each through hole 254 penetrates the hollow portion 25 in the thickness direction (radial direction). Specifically, the front plate portion 23 is coupled to the hollow portion 25 by a pair of screws 284 inserted into a pair of through holes 254 from the side. At this time, a pair of screws 284 are fastened to a pair of protrusions protruding rearward from the back (rear) of the front plate portion 23.

蓋體26係裝設於中空部25的後端部，並封閉中空部25的背面（後面）。除了蓋體26的後端部之外，在前視觀察下，蓋體26的外周緣係與中空部25的內周緣大略一致。再者，在前視觀察下，蓋體26的後端部係比中空部25之開口面稍微較大地形成。因此，蓋體26係以從後方嵌入的方式裝設於中空部25的後端部，而至少限制蓋體26相對於中空部25往與前後方向垂直之方向移動。The cover 26 is installed at the rear end of the hollow part 25 and closes the back (rear) of the hollow part 25. Except for the rear end portion of the cover body 26, the outer periphery of the cover body 26 is approximately the same as the inner periphery of the hollow portion 25 in front view. Furthermore, in front view, the rear end portion of the lid body 26 is formed slightly larger than the opening surface of the hollow portion 25. Therefore, the cover 26 is installed at the rear end of the hollow portion 25 in a manner of being embedded from the rear, and at least the cover 26 is restricted from moving relative to the hollow portion 25 in a direction perpendicular to the front-rear direction.

此處，在蓋體26係形成有凹部261。凹部261係藉由使蓋體26之前面的一部分形成為往後方凹陷的形狀，而朝前方開放。在本實施態樣中，就一例而言，凹部261為了收納功能部21的後端部，而比功能部21之後端部大一圈地形成。Here, a recess 261 is formed in the cover 26. The recess 261 is opened forward by forming a part of the front surface of the lid body 26 into a shape recessed rearward. In this embodiment, as an example, the recessed portion 261 is formed so as to accommodate the rear end of the functional portion 21, and is formed to be substantially larger than the rear end of the functional portion 21.

又，蓋體26更包含用於通過上述一對螺絲281的一對穿通孔262。亦即，藉由將一對螺絲281通過一對穿通孔262並鎖緊於一對螺孔251，而使蓋體26與中空部25結合。In addition, the cover 26 further includes a pair of through holes 262 for passing through the pair of screws 281. That is, by passing a pair of screws 281 through a pair of through holes 262 and locking them to a pair of screw holes 251, the cover 26 and the hollow portion 25 are combined.

又，一對連接端子24係固定於蓋體26的背面（後面）。一對連接端子24係配置於蓋體26之背面中的左右方向之兩端部，並藉由一對螺絲283固定於蓋體26。各連接端子24係以具有導電性之金屬板，例如銅或是銅合金等金屬板構成。一對連接端子24各自之後端部係形成為往內側，亦即往互相靠近之方向彎曲的形狀。藉此，藉由使第二單元2在一對連接端子24***一對連接口111（參照圖3）的狀態下，於前視觀察下往順時針旋轉，而使一對連接端子24與電力接收部11扣接，進而與電力接收部11電性且機械連接。In addition, a pair of connection terminals 24 are fixed to the back surface (rear surface) of the cover 26. A pair of connecting terminals 24 are arranged at both ends in the left-right direction on the back of the cover body 26 and fixed to the cover body 26 by a pair of screws 283. Each connection terminal 24 is made of a conductive metal plate, such as a metal plate such as copper or copper alloy. The rear ends of the pair of connection terminals 24 are respectively formed in a shape that is curved toward the inner side, that is, in a direction approaching each other. Thereby, by making the second unit 2 rotate clockwise in front view with the pair of connecting terminals 24 inserted into the pair of connecting ports 111 (refer to FIG. 3), the pair of connecting terminals 24 and the electric power The receiving part 11 is buckled, and then electrically and mechanically connected to the power receiving part 11.

前板部23包含一對***孔231，形成於與功能部21之一對***口211對應的位置，且形成為與功能部21之一對***口211對應的形狀。一對***孔231係在前板部23之前面的中央部形成開口，並在厚度方向（前後方向）上貫穿前板部23。具體而言，一對***孔231係在前視觀察下，形成於與一對***口211相同的位置且形成為與一對***口211相同的形狀，而與功能部21的一對***口211重疊。因此，在將負載4之插頭連接於功能部21時，插頭中的一對***片41係通過一對***孔231而******口211。又，在一對***片41通過一對***孔231而***一對***口211的狀態下，負載4係與功能部21電性且機械連接。The front plate portion 23 includes a pair of insertion holes 231 formed at positions corresponding to a pair of insertion openings 211 of the functional portion 21 and formed in a shape corresponding to a pair of insertion openings 211 of the functional portion 21. A pair of insertion holes 231 form an opening in the center portion of the front surface of the front plate portion 23 and penetrate the front plate portion 23 in the thickness direction (front-rear direction). Specifically, a pair of insertion holes 231 are formed in the same position as the pair of insertion ports 211 in front view, and are formed in the same shape as the pair of insertion ports 211, and are similar to the pair of insertion ports of the functional part 21 211 overlap. Therefore, when the plug of the load 4 is connected to the functional part 21, the pair of insertion pieces 41 in the plug are inserted into the insertion opening 211 through the pair of insertion holes 231. In addition, in a state where the pair of insertion pieces 41 are inserted into the pair of insertion ports 211 through the pair of insertion holes 231, the load 4 is electrically and mechanically connected to the functional portion 21.

安裝蓋體27係裝設於中空部25的前端部，並具有將功能部21固定於中空部25（圓形部22）的功能。在本實施態樣中，就一例而言，安裝蓋體27為金屬製，並且在前視觀察下形成為略圓形。在前視觀察下，安裝蓋體27的外周緣係與中空部25的內周緣大略一致。因此，安裝蓋體27係以從前方嵌入的方式裝設於中空部25的前端部，而至少限制安裝蓋體27相對於中空部25往與前後方向垂直的方向移動。The mounting cover 27 is installed at the front end of the hollow part 25 and has a function of fixing the functional part 21 to the hollow part 25 (circular part 22). In this embodiment, as an example, the mounting cover 27 is made of metal, and is formed in a slightly circular shape in front view. In front view, the outer periphery of the mounting cover 27 is roughly the same as the inner periphery of the hollow part 25. Therefore, the mounting cover 27 is mounted to the front end of the hollow portion 25 in a manner of being fitted from the front, and at least the mounting cover 27 is restricted from moving relative to the hollow portion 25 in a direction perpendicular to the front-rear direction.

此處，在安裝蓋體27中，係形成有於厚度方向（前後方向）上貫穿安裝蓋體27的安裝孔271。此處，安裝孔271係在前視觀察下，形成於安裝蓋體27的大部分而僅殘留安裝蓋體27之外周部，以使安裝蓋體27成為框體。Here, in the mounting cover 27, a mounting hole 271 penetrating the mounting cover 27 in the thickness direction (front-rear direction) is formed. Here, the mounting hole 271 is formed in most of the mounting cover 27 in front view, and only the outer peripheral portion of the mounting cover 27 remains, so that the mounting cover 27 becomes a frame.

在本實施態樣中，就一例而言，在前視觀察下，安裝孔271的內周緣係與功能部21之前端部的外周緣大略一致。因此，在將安裝蓋體27與功能部21加以組合的狀態下，功能部21的前端部會通過安裝蓋體27的安裝孔271，而從安裝蓋體27的前面往前方突出。In this embodiment, for one example, in front view, the inner peripheral edge of the mounting hole 271 is roughly the same as the outer peripheral edge of the front end of the functional portion 21. Therefore, in a state where the mounting cover 27 and the functional portion 21 are combined, the front end of the functional portion 21 passes through the mounting hole 271 of the mounting cover 27 and protrudes forward from the front surface of the mounting cover 27.

又，安裝蓋體27更包含用於穿過上述一對螺絲282的一對穿通孔272。亦即，藉由將一對螺絲282通過一對穿通孔272並鎖緊於一對螺孔251，而使安裝蓋體27與中空部25結合。In addition, the mounting cover 27 further includes a pair of through holes 272 for passing through the pair of screws 282. That is, by passing a pair of screws 282 through a pair of through holes 272 and locking them to a pair of screw holes 251, the mounting cover 27 and the hollow portion 25 are combined.

又，在安裝蓋體27與中空部25結合的狀態下，安裝蓋體27係將功能部21固定於中空部25（圓形部22）。在本實施態樣中，就一例而言，安裝蓋體27係藉由至少將功能部21的一部分（此處為安裝片213）夾在中空部25中的一對固定部252之間，而將功能部21固定於中空部25（圓形部22）。具體而言，在功能部21的各安裝片213嵌入於固定部252之各固定凹部253的狀態下，藉由安裝蓋體27從前方壓緊功能部21之各安裝片213，而使安裝蓋體27將各安裝片213固持於各固定凹部253內。藉此，將功能部21固定於中空部25（圓形部22）。Furthermore, in a state where the attachment cover 27 and the hollow portion 25 are coupled, the attachment cover 27 fixes the functional portion 21 to the hollow portion 25 (circular portion 22). In this embodiment, for one example, the cover 27 is installed by sandwiching at least a part of the functional portion 21 (here, the mounting piece 213) between a pair of fixing portions 252 in the hollow portion 25, and The functional part 21 is fixed to the hollow part 25 (circular part 22). Specifically, in a state in which the mounting pieces 213 of the functional part 21 are fitted into the fixing recesses 253 of the fixing part 252, the mounting cover 27 presses the mounting pieces 213 of the functional part 21 from the front, so that the cover The body 27 holds each mounting piece 213 in each fixing recess 253. Thereby, the functional part 21 is fixed to the hollow part 25 (circular part 22).

藉由將如以上所說明之構成的功能部21、圓形部22（中空部25及蓋體26）、前板部23、一對連接端子24及安裝蓋體27加以組合，而構成第二單元2。By combining the functional part 21, the circular part 22 (the hollow part 25 and the cover body 26), the front plate part 23, the pair of connection terminals 24, and the mounting cover body 27 as described above, the second part is formed. Unit 2.

（3）第二單元之更換例 接著，參照圖5說明依本實施態樣之配線器具系統10中之第二單元2的更換例。圖5係示意地顯示第二單元2之更換例的說明圖，例如，適當簡化而圖示從施工孔33露出之第一單元1的形狀等。(3) Replacement example of the second unit Next, a replacement example of the second unit 2 in the wiring appliance system 10 according to the present embodiment will be described with reference to FIG. 5. FIG. 5 is an explanatory diagram schematically showing an example of replacement of the second unit 2. For example, the shape of the first unit 1 exposed from the construction hole 33 is shown in simplified form as appropriate.

在本實施態樣中，可對第一單元1裝設複數種類的第二單元201~207。在未特別區別複數種類之第二單元201~207的情況下，係將複數種類的各第二單元201~207僅稱為「第二單元2」。亦即，在依本實施態樣的配線器具系統10中，係以將第二單元2裝設於第一單元1的方式，而將整個配線器具系統10裝設於施工對象物3。因此，在依本實施態樣的配線器具系統10中，可在留下固定於施工對象物3的第一單元1的狀態下，僅將第二單元2更換成另一個第二單元2。藉此，在配線器具系統10中，例如藉由將第二單元202~207代替如上述般具有作為插座（Outlet）之功能的第二單元201，而裝設於第一單元1，可自由地替換功能。就結果而言，在配線器具系統10中，可實現具有各式各樣功能的配線器具。In this embodiment, multiple types of second units 201 to 207 can be installed on the first unit 1. In the case where the plural types of second units 201 to 207 are not particularly distinguished, the plural types of second units 201 to 207 are simply referred to as "second unit 2". That is, in the wiring appliance system 10 according to this embodiment, the second unit 2 is installed in the first unit 1 and the entire wiring appliance system 10 is installed on the construction target 3. Therefore, in the wiring appliance system 10 according to this embodiment, it is possible to replace only the second unit 2 with another second unit 2 while leaving the first unit 1 fixed to the construction object 3. Thereby, in the wiring appliance system 10, for example, by replacing the second unit 201 having the function as an outlet as described above with the second units 202 to 207, and installing them in the first unit 1, it is possible to freely Replacement function. As a result, in the wiring fixture system 10, wiring fixtures with various functions can be realized.

亦即，如圖5所示，透過提供複數種類的第二單元2，可藉由配線器具系統10而實現各式各樣配線器具的功能。就與第一單元1電性及機械連接有關的構成而言，該等複數種類的第二單元202~207係採用與第二單元201共通的構成。又，該等複數種類的第二單元201~207，係形成為在前視觀察下的形狀及尺寸為相同。因此，各第二單元2係在***第一單元1後，藉由在前視觀察下相對於第一單元1往順時針旋轉，而裝設於第一單元1。That is, as shown in FIG. 5, by providing multiple types of second units 2, the wiring fixture system 10 can implement various wiring fixture functions. In terms of the structure related to the electrical and mechanical connection of the first unit 1, the plural types of second units 202 to 207 adopt the same structure as the second unit 201. In addition, the plural types of second units 201 to 207 are formed to have the same shape and size in front view. Therefore, each second unit 2 is installed in the first unit 1 by rotating clockwise with respect to the first unit 1 in front view after being inserted into the first unit 1.

在圖5的例子中，第二單元202係包含旋鈕、旋轉編碼器或旋轉開關等旋轉操作型的使用者介面，並具有作為負載控制裝置之功能的配線器具。此第二單元202係藉由根據使用者介面所接收到之使用者的操作，而對照明器具等負載4控制通電狀態，進而控制負載4。第二單元203係具有作為USB（Universal Serial Bus）插座（Outlet）之功能的配線器具。此第二單元203具有可使負載4之USB插頭***連接的USB插孔型連接器，並可經由USB插頭對負載4輸出5V的直流電壓。In the example of FIG. 5, the second unit 202 includes a rotary operation type user interface such as a knob, a rotary encoder, or a rotary switch, and has a wiring appliance that functions as a load control device. The second unit 202 controls the energized state of the load 4 such as lighting equipment according to the user's operation received by the user interface, and then controls the load 4. The second unit 203 is a wiring appliance that functions as a USB (Universal Serial Bus) outlet. The second unit 203 has a USB jack type connector for inserting and connecting the USB plug of the load 4, and can output a DC voltage of 5V to the load 4 via the USB plug.

又，第二單元204係具有作為藉由磁力吸附插頭之磁鐵插座（Outlet）之功能的配線器具。此第二單元204係藉由以磁鐵的磁力吸引負載4的插頭，而經由插頭對負載4供給交流或直流的電力。第二單元205係包含人體感測器或是明亮度等感測器，且具有作為負載控制裝置之功能的配線器具。此第二單元205係根據感測器的偵測結果，而藉由對照明器具等負載4控制通電狀態，進而控制負載4。In addition, the second unit 204 is a wiring appliance that functions as a magnet outlet (outlet) for attracting a plug by magnetic force. The second unit 204 attracts the plug of the load 4 with the magnetic force of the magnet, and supplies AC or DC power to the load 4 through the plug. The second unit 205 is a wiring appliance that includes a human body sensor or a brightness sensor, and has a function as a load control device. The second unit 205 controls the power-on state of the load 4 such as lighting equipment according to the detection result of the sensor, thereby controlling the load 4.

又，第二單元206係包含按鈕式、翹板式或觸碰式的使用者介面，且具有作為開關裝置之功能的配線器具。此第二單元206係根據使用者介面所接收到的使用者之操作，而藉由對照明器具等負載4控制通電狀態，進而控制負載4。特別是，第二單元206係包含複數（此處為四個）使用者介面，並具有複數（此處為四個）開關作為功能部21。因此，藉由一個第二單元206，可控制複數（此處為四個）負載4。又，第二單元207係包含按鈕式、翹板式或觸碰式的使用者介面，且具有作為開關裝置之功能的配線器具。此第二單元207係根據使用者介面所接收到的使用者之操作，而藉由對照明器具等負載4控制通電狀態，進而控制負載4。In addition, the second unit 206 is a wiring appliance that includes a button-type, rocker-type or touch-type user interface and functions as a switch device. The second unit 206 controls the power-on state of the load 4 such as lighting equipment according to the user's operation received by the user interface, thereby controlling the load 4. In particular, the second unit 206 includes a plurality of (here, four) user interfaces, and has a plurality of (here, four) switches as the functional unit 21. Therefore, with one second unit 206, multiple (here, four) loads 4 can be controlled. In addition, the second unit 207 is a wiring appliance that includes a button-type, rocker-type or touch-type user interface and functions as a switch device. The second unit 207 controls the load 4 by controlling the power-on state of the load 4 such as lighting equipment according to the operation of the user received by the user interface.

簡而言之，在依本實施態樣的配線器具系統10中，作為配線器具的第二單元2，係可取下地裝設於固定在施工對象物3的第一單元1。因此，藉由將第二單元2從第一單元1取下，可僅將第二單元2從施工對象物3取下。此時，由於具備用於接收電力供給之電力接收部11的第一單元1尚留在施工對象物3側，故即使不進行對電力接收部11之配線的重新連接，亦可更換作為配線器具的第二單元2。從而，在如上述般提供複數種類之第二單元2的情況下，藉由第二單元2的更換，可藉由配線器具系統10而實現各式各樣的配線器具之功能。In short, in the wiring appliance system 10 according to the present embodiment, the second unit 2 as the wiring appliance is detachably installed in the first unit 1 fixed to the construction object 3. Therefore, by removing the second unit 2 from the first unit 1, only the second unit 2 can be removed from the construction target 3. At this time, since the first unit 1 including the power receiving unit 11 for receiving power supply is still on the side of the construction object 3, it can be replaced as a wiring appliance even without reconnecting the wiring of the power receiving unit 11 The second unit 2. Therefore, when plural types of second units 2 are provided as described above, by replacing the second units 2, the wiring fixture system 10 can realize the functions of various wiring fixtures.

再者，由於第一單元1係被複數種類的第二單元2共有，故即使在變更作為整個配線器具系統10的配線器具之種類的情況下，亦可再利用第一單元1。又，不僅從既設之第二單元2更換成其他第二單元2的情況，在新設第二單元2的情況，亦可採用如上述之各種的第二單元2。Furthermore, since the first unit 1 is shared by a plurality of types of second units 2, even when the type of wiring equipment as the entire wiring equipment system 10 is changed, the first unit 1 can be reused. In addition, not only in the case of replacing the existing second unit 2 with another second unit 2, but also in the case of newly installing the second unit 2, various second units 2 as described above can also be used.

此外，在依本實施態樣的配線器具系統10中，裝設空間12亦可裝設「接收來自第一單元1之電力供給而動作的設備601、602」，以代替裝設第二單元2。在圖5中，係顯示了複數種類（此處為兩種）的設備601、602，但在未特別區別複數種類之設備601、602的情況下，係將複數種類之設備601、602各自僅稱為「設備6」。亦即，在本實施態樣之配線器具系統10中，係以將第二單元2裝設於第一單元1的方式，而將整個配線器具系統10裝設於施工對象物3。因此，在依本實施態樣的配線器具系統10中，可在將固定於施工對象物3的第一單元1留著的狀態下，將第二單元2更換成設備6。In addition, in the wiring appliance system 10 according to the present embodiment, the installation space 12 can also be installed with "equipment 601, 602 operating by receiving the power supply from the first unit 1," instead of installing the second unit 2. . In Fig. 5, devices 601 and 602 of plural types (two types here) are shown, but in the case that the plural types of devices 601 and 602 are not specifically distinguished, the plural types of devices 601 and 602 are only Called "Device 6". That is, in the wiring appliance system 10 of this embodiment, the second unit 2 is installed in the first unit 1 and the entire wiring appliance system 10 is installed on the construction target 3. Therefore, in the wiring appliance system 10 according to this embodiment, the second unit 2 can be replaced with the equipment 6 while the first unit 1 fixed to the construction object 3 is left.

此處，關於設備6，亦如圖5所示，透過提供複數種類之設備601、602，便可藉由配線器具系統10而實現各式各樣的設備6之功能。該等複數種類的設備601、602中，就與第一單元1電性及機械連接有關的構成而言，係採用與第二單元201共通的構成。又，該等複數種類的設備601、602在前視觀察下的形狀及尺寸，係形成為與第二單元2相同。因此，各設備6在***第一單元1後，藉由在前視觀察下相對於第一單元1往順時針旋轉，而裝設於第一單元1。Here, regarding the equipment 6, as shown in FIG. 5, by providing multiple types of equipment 601 and 602, various functions of the equipment 6 can be realized by the wiring appliance system 10. Among these plural types of devices 601 and 602, the configuration related to the electrical and mechanical connection of the first unit 1 is a configuration common to the second unit 201. In addition, the shapes and sizes of the plural types of devices 601 and 602 in front view are formed to be the same as those of the second unit 2. Therefore, after each device 6 is inserted into the first unit 1, it is installed in the first unit 1 by rotating clockwise relative to the first unit 1 in front view.

在圖5的例子中，設備601具有作為輸出光之照明設備（包含下照燈、緊急照明燈及地腳燈等）的功能。此設備601係藉由接收來自第一單元1的電力供給使光源點燈，而照明周圍。設備602具有作為輸出聲音（包含語音、嗶聲及旋律等）之聲音輸出設備（包含揚聲器及AI揚聲器）的功能。此設備602係接收來自第一單元1的電力供給，並藉由將電信號轉換成聲音，而將聲音輸出。In the example of FIG. 5, the device 601 has a function as a lighting device that outputs light (including downlights, emergency lights, foot lights, etc.). The device 601 illuminates the light source by receiving the power supply from the first unit 1 to illuminate the surroundings. The device 602 has a function as a sound output device (including a speaker and an AI speaker) that outputs sounds (including voice, beep, melody, etc.). The device 602 receives the power supply from the first unit 1, and converts the electrical signal into sound to output the sound.

然而，圖5所示之設備6僅為一例，除了照明設備及聲音輸出設備之外，例如亦可採用顯示器、通訊設備或是量測設備等作為設備6。However, the device 6 shown in FIG. 5 is only an example. In addition to the lighting device and the sound output device, for example, a display, a communication device, or a measurement device can also be used as the device 6.

（4）變形例 實施態樣1僅為本發明之各式各樣的實施態樣中的一個。只要可達成本發明之目的，實施態樣1可因應設計等進行各種的變更。在本發明中，說明之各圖係示意性的圖式，各圖中之各構成元件的大小及厚度各自的比例，不一定反映實際的尺寸比例。(4) Modifications Embodiment 1 is only one of the various embodiments of the present invention. As long as the purpose of the invention can be achieved, implementation mode 1 can be modified in various ways according to the design. In the present invention, the illustrated drawings are schematic drawings, and the respective ratios of the sizes and thicknesses of the constituent elements in the drawings do not necessarily reflect the actual size ratios.

以下，列舉實施態樣1的變形例。以下所說明的變形例，可適當組合以應用。以下，針對與實施態樣1相同之構成，係賦予共通的符號並適當省略說明。Hereinafter, modification examples of Embodiment 1 will be listed. The modified examples described below can be appropriately combined and applied. Hereinafter, with respect to the same configuration as that of Embodiment 1, common symbols are assigned, and descriptions are appropriately omitted.

（4.1）第一變形例 在依第一變形例之配線器具系統10A中，係如圖6A~圖6C所示，裝設空間12的形狀與實施態樣1的配線器具系統10不同。在圖6A~圖6C中，係以假想線（兩點鎖線）顯示第二單元2。在圖6A~圖6C中，例如適當簡化而圖示從施工孔33露出之第一單元1的形狀等。(4.1) First modification In the wiring appliance system 10A according to the first modification, as shown in FIGS. 6A to 6C, the shape of the installation space 12 is different from the wiring appliance system 10 of the first embodiment. In FIGS. 6A to 6C, the second unit 2 is shown by an imaginary line (two-point lock line). In FIGS. 6A to 6C, for example, the shape of the first unit 1 exposed from the construction hole 33 and the like are shown in simplified form as appropriate.

在本變形例中，第一單元1例如係採用如I型之插座（Outlet）的***式連接器，來代替天花板接線盒作為用於電性且機械連接第二單元2的構成。具體而言，第一單元1在其前面具有構成I型之插座（Outlet）的貫穿孔142A。藉此，從第二單元2之背面（後面）往後方突出的複數刃片會從前方***貫穿孔142A，而將第二單元2與第一單元1的電力接收部11電性且機械連接。因此，在本變形例中，當將第二單元2裝設至裝設空間12時，會伴隨第二單元2相對於第一單元1的直線移動，但不容易伴隨第二單元2對於第一單元1的相對旋轉。In this modification, the first unit 1 uses, for example, a plug-in connector such as an I-type outlet instead of a ceiling junction box as a structure for electrically and mechanically connecting the second unit 2. Specifically, the first unit 1 has a through hole 142A forming an I-type outlet (Outlet) on the front surface thereof. In this way, the plurality of blades protruding from the back (rear) of the second unit 2 are inserted into the through hole 142A from the front to electrically and mechanically connect the second unit 2 with the power receiving portion 11 of the first unit 1. Therefore, in this modification, when the second unit 2 is installed in the installation space 12, it will be accompanied by the linear movement of the second unit 2 relative to the first unit 1, but it is not easy to follow the second unit 2 to the first unit 1. Relative rotation of unit 1.

如此，在不容易伴隨第二單元2之旋轉的情況下，裝設空間12的形狀便不限於如圓形這樣旋轉對稱的形狀，而可採用適當的形狀。在圖6A的例子中，裝設空間12在前視觀察下係形成為正方形。此情況下，在第二單元2亦採用前視觀察下呈正方形之構成，以代替圓形部22。在圖6B的例子中，裝設空間12在前視觀察下係形成為略三角形。此情況下，在第二單元2亦採用前視觀察下呈略三角形之構成，以代替圓形部22。又，在圖6C的例子中，裝設空間12在前視觀察下係形成為橢圓形。此情況，在第二單元2亦採用前視觀察下呈橢圓形之構成，以代替圓形部22。In this way, when the rotation of the second unit 2 is not easily accompanied, the shape of the installation space 12 is not limited to a rotationally symmetrical shape such as a circle, and an appropriate shape can be adopted. In the example of FIG. 6A, the installation space 12 is formed as a square in front view. In this case, the second unit 2 also adopts a square structure in front view instead of the circular portion 22. In the example of FIG. 6B, the installation space 12 is formed in a slightly triangular shape in front view. In this case, the second unit 2 also adopts a slightly triangular configuration in front view instead of the circular portion 22. Moreover, in the example of FIG. 6C, the installation space 12 is formed in an elliptical shape in front view. In this case, the second unit 2 also adopts an elliptical configuration in front view instead of the circular portion 22.

如此，根據第一變形例，由於在將第二單元2裝設至裝設空間12時，不容易伴隨第二單元2對於第一單元1的相對旋轉，因此易於確定第二單元2的方向。In this way, according to the first modification, since the relative rotation of the second unit 2 with respect to the first unit 1 is not easily accompanied when the second unit 2 is installed in the installation space 12, the direction of the second unit 2 is easily determined.

（4.2）第二變形例 在依第二變形例的配線器具系統10B中，係如圖7A~圖7C所示，可改變裝設於裝設空間12之狀態下的第二單元2之姿態。本發明中所謂的「姿態」，係意指固定於施工對象物3之狀態下的第二單元2之方向及位置等。在圖7A中，係以假想線（兩點鎖線）顯示第二單元2。在圖7A~圖7C中，例如適當簡化而圖示從施工孔33露出之第一單元1的形狀等。(4.2) Second modification In the wiring appliance system 10B according to the second modification example, as shown in FIGS. 7A to 7C, the posture of the second unit 2 installed in the installation space 12 can be changed. The "posture" in the present invention means the direction and position of the second unit 2 in a state fixed to the construction target 3, and the like. In Fig. 7A, the second unit 2 is shown with an imaginary line (two-point lock line). In FIGS. 7A to 7C, for example, the shape of the first unit 1 exposed from the construction hole 33 and the like are shown in simplified form as appropriate.

在本變形例中，第一單元1例如係採用如耳機插孔（phone jack）這樣的***式連接器，來代替天花板接線盒作為電性且機械連接第二單元2的構成。具體而言，第一單元1係在其前面的中央部，具有構成兩極之耳機插孔的貫穿孔142B。藉此，從第二單元2之背面（後面）往後方突出的耳機插頭，會從前方***貫穿孔142B，而將第二單元2與第一單元1的電力接收部11電性且機械連接。因此，在本變形例中，當將第二單元2裝設至裝設空間12時，會伴隨第二單元2相對於第一單元1的直線移動，但不容易伴隨第二單元2對於第一單元1的相對旋轉。In this modification, the first unit 1 adopts, for example, a plug-in connector such as a phone jack instead of a ceiling junction box as a structure for electrically and mechanically connecting the second unit 2. Specifically, the first unit 1 is located at the center of the front surface, and has a through hole 142B that constitutes a two-pole earphone jack. Thereby, the earphone plug protruding from the back (rear) of the second unit 2 will be inserted into the through hole 142B from the front to electrically and mechanically connect the second unit 2 with the power receiving portion 11 of the first unit 1. Therefore, in this modification, when the second unit 2 is installed in the installation space 12, it will be accompanied by the linear movement of the second unit 2 relative to the first unit 1, but it is not easy to follow the second unit 2 to the first unit 1. Relative rotation of unit 1.

再者，在本變形例中，貫穿孔142B係配置於第一單元1之前面的中央部。根據如此之構成，在耳機插頭***貫穿孔142B（耳機插孔）的狀態下，如圖7B及圖7C所示，可使第二單元2對於第一單元1相對旋轉。就一例而言，藉由相對於第一單元1往箭頭A3（參照圖7C）的方向旋轉，而使第二單元2的姿態改變。在圖7C的例子中，係在前視觀察下使第二單元2從圖7B的例子往順時針旋轉90度，藉此，使一對***孔231變成在上下方向上並列。In addition, in this modification, the through hole 142B is arranged in the center portion of the front surface of the first unit 1. According to such a configuration, when the earphone plug is inserted into the through hole 142B (earphone jack), as shown in FIGS. 7B and 7C, the second unit 2 can be relatively rotated with respect to the first unit 1. For one example, by rotating in the direction of arrow A3 (refer to FIG. 7C) relative to the first unit 1, the posture of the second unit 2 is changed. In the example of FIG. 7C, the second unit 2 is rotated 90 degrees clockwise from the example of FIG. 7B in front view, whereby the pair of insertion holes 231 are aligned in the vertical direction.

如此，根據第二變形例，可在第二單元2裝設於第一單元1之裝設空間12的狀態下，使第二單元2的姿態改變。In this way, according to the second modification, the posture of the second unit 2 can be changed in the state where the second unit 2 is installed in the installation space 12 of the first unit 1.

（4.3）第三變形例 在依第三變形例的配線器具系統10C中，如圖8A所示，第一單元1係包含安裝框74。安裝框74例如係根據日本工業標準而標準化之大角形連用配線器具之安裝框。亦即，在本變形例中，配線器具系統10C係使用安裝框74而固定於施工對象物3。(4.3) Third modification In the wiring appliance system 10C according to the third modification, as shown in FIG. 8A, the first unit 1 includes a mounting frame 74. The mounting frame 74 is, for example, a mounting frame of a large-angle connecting wiring appliance standardized in accordance with Japanese Industrial Standards. That is, in this modification example, the wiring appliance system 10C is fixed to the construction target 3 using the mounting frame 74.

在圖8A的例子中，第一單元1的開關盒13係固定於安裝框74。再者，妝飾框75可直接或是間接地安裝於安裝框74。藉此，在配線器具系統10C固定於施工對象物3的狀態下，可藉由妝飾框75覆蓋住第二單元2的周圍，而使外觀變得良好。In the example of FIG. 8A, the switch box 13 of the first unit 1 is fixed to the mounting frame 74. Furthermore, the makeup frame 75 can be directly or indirectly mounted on the installation frame 74. Thereby, in the state where the wiring appliance system 10C is fixed to the construction target 3, the periphery of the second unit 2 can be covered by the decorative frame 75, and the appearance can be improved.

（4.4）第四變形例 依第四變形例的配線器具系統10D，如圖8B所示，第一單元1與第二單元2係藉由電纜71而電性連接。在電纜71的一端部係設有連接器72。在電纜71中之與連接器72相反側的端部，係與第二單元2連接。因此，藉由將連接器72與第一單元1連接，而經由電纜71將第一單元1與第二單元2電性連接。在本變形例中，第一單元1與第二單元2之間的電性連接與機械連接（結合），係以不同的手段實現。(4.4) Fourth modification According to the wiring appliance system 10D of the fourth modification, as shown in FIG. 8B, the first unit 1 and the second unit 2 are electrically connected by a cable 71. A connector 72 is provided at one end of the cable 71. The end of the cable 71 opposite to the connector 72 is connected to the second unit 2. Therefore, by connecting the connector 72 with the first unit 1, the first unit 1 and the second unit 2 are electrically connected via the cable 71. In this modification, the electrical connection and mechanical connection (combination) between the first unit 1 and the second unit 2 are realized by different means.

又，在本變形例中，第一單元1與第二單元2中的至少一者具有電力轉換部73。電力轉換部73係進行電力的轉換。亦即，配線器具系統10D係藉由設於第一單元1及/或是第二單元2的電力轉換部73，而進行電力的轉換。本發明中所謂的「電力之轉換」，例如包含從交流電力轉換成直流電力、從直流電力轉換成交流電力、及電壓的轉換等。電力轉換部73係以進行該等轉換的電路而實現。在本變形例中，就一例而言，電力轉換部73例如係將100V的交流電力轉換成5V、12V、24V或48V之直流電力的AC-DC轉換器。In addition, in this modification, at least one of the first unit 1 and the second unit 2 has a power conversion unit 73. The power conversion unit 73 performs power conversion. That is, the wiring appliance system 10D performs power conversion by the power conversion unit 73 provided in the first unit 1 and/or the second unit 2. The "conversion of power" in the present invention includes, for example, conversion from AC power to DC power, conversion from DC power to AC power, and conversion of voltage. The power conversion unit 73 is realized by a circuit that performs these conversions. In this modification example, as an example, the power conversion unit 73 is, for example, an AC-DC converter that converts 100V AC power into 5V, 12V, 24V, or 48V DC power.

在本變形例中，特別係將電力轉換部73設於第一單元1。亦即，電力轉換部73係被收納於第一單元1的開關盒13內。引入第一單元1的配線51係與電力轉換部73連接。又，藉由將連接器72與電力轉換部73連接，第二單元2會經由電纜71而與第一單元1的電力轉換部73連接。In this modification, in particular, the power conversion unit 73 is provided in the first unit 1. That is, the power conversion unit 73 is housed in the switch box 13 of the first unit 1. The wiring 51 introduced into the first unit 1 is connected to the power conversion unit 73. In addition, by connecting the connector 72 to the power conversion unit 73, the second unit 2 is connected to the power conversion unit 73 of the first unit 1 via the cable 71.

（4.5）第五變形例 在依第五變形例的配線器具系統10E中，如圖8C所示，電力轉換部73係與第一單元1分開地設置。此處，電力轉換部73係經由配線51而與第一單元1電性連接。再者，電力轉換部73，係藉由另一配線52，並經由配電盤53（參照圖8D）等電力設備，而與系統電源或是分散電源等電源電性連接。(4.5) Fifth modification In the wiring appliance system 10E according to the fifth modification, as shown in FIG. 8C, the power conversion unit 73 is provided separately from the first unit 1. Here, the power conversion unit 73 is electrically connected to the first unit 1 via the wiring 51. Furthermore, the power conversion unit 73 is electrically connected to a power source such as a system power source or a distributed power source through another wiring 52 and power equipment such as a switchboard 53 (see FIG. 8D).

亦即，在本變形例中，電力轉換部73具有從第一單元1獨立出的殼體，並與第一單元1分開設置。如此之電力轉換部73例如配置於牆板31的背面側（牆壁裡）、頂棚面板的背面側（頂棚裡）或是地板下等適當的位置。如此，藉由將電力轉換部73與第一單元1各別分開，可實現第一單元1的小型化。That is, in this modification example, the power conversion unit 73 has a housing separate from the first unit 1 and is provided separately from the first unit 1. Such a power conversion unit 73 is arranged at an appropriate position such as the back side (in the wall) of the wall panel 31, the back side of the ceiling panel (in the ceiling), or under the floor. In this way, by separating the power conversion part 73 from the first unit 1 separately, the miniaturization of the first unit 1 can be achieved.

又，在圖8C的例子中，第一單元1係採用天花板接線盒，作為用於電性且機械連接第二單元2的構成。然而，本發明並不限定於此，例如，亦可與第四變形例相同，第一單元1與第二單元2係以電纜71而電性連接。In addition, in the example of FIG. 8C, the first unit 1 adopts a ceiling junction box as a structure for electrically and mechanically connecting the second unit 2. However, the present invention is not limited to this. For example, as in the fourth modification, the first unit 1 and the second unit 2 are electrically connected by a cable 71.

（4.6）第六變形例 在依第六變形例的配線器具系統10F中，如圖8D所示，電力轉換部73係配置於配電盤53內。此處，電力轉換部73係經由配線51而與第一單元1電性連接。再者，電力轉換部73係在配電盤53的箱內例如與分路斷路器電性連接。(4.6) The sixth modification In the wiring appliance system 10F according to the sixth modification example, as shown in FIG. 8D, the power conversion unit 73 is arranged in the switchboard 53. Here, the power conversion unit 73 is electrically connected to the first unit 1 via the wiring 51. In addition, the power conversion unit 73 is electrically connected to, for example, a branch circuit breaker in the box of the switchboard 53.

亦即，在本變形例中，電力轉換部73具有從第一單元1獨立出的殼體，並與第一單元1分開設置。因此，在本變形例中，亦與第四變形例相同，藉由將電力轉換部73與第一單元1各別分開，可實現第一單元1的小型化。That is, in this modification example, the power conversion unit 73 has a housing separate from the first unit 1 and is provided separately from the first unit 1. Therefore, in this modification, as in the fourth modification, by separately separating the power conversion portion 73 from the first unit 1, the size of the first unit 1 can be reduced.

（實施態樣2） 依本實施態樣的配線器具系統10G，如圖9A及圖9B所示，在第一單元1具有複數裝設空間12此點，與依實施態樣1的配線器具系統10不同。以下，針對與實施態樣1相同之構成，係賦予共通的符號而適當省略說明。在圖9A中，係以假想線（兩點鎖線）顯示第二單元2。(Implementation Pattern 2) The wiring appliance system 10G according to this embodiment is different from the wiring appliance system 10 according to the first embodiment in that the first unit 1 has a plurality of installation spaces 12 as shown in FIGS. 9A and 9B. Hereinafter, with respect to the same configuration as that of the first embodiment, the common symbols are assigned, and the description is appropriately omitted. In Fig. 9A, the second unit 2 is shown with an imaginary line (two-point lock line).

在本實施態樣中，如圖9A所示，第一單元1具有三個裝設空間12。在各裝設空間12可裝設一個第二單元2。因此，對一個第一單元1而言，最多可裝設三個第二單元2。In this embodiment, as shown in FIG. 9A, the first unit 1 has three installation spaces 12. A second unit 2 can be installed in each installation space 12. Therefore, for one first unit 1, at most three second units 2 can be installed.

在圖9A的例子中，該等複數（此處為三個）裝設空間12，係在左右方向上並列配置。又，三個裝設空間12各自係配有構成I型插座（Outlet）的三個貫穿孔142G。亦即，在本實施態樣中，係與實施態樣1之第一變形例相同，採用在將第二單元2裝設至裝設空間12時，不容易伴隨第二單元2對第一單元1的相對旋轉之構成。In the example of FIG. 9A, the plural installation spaces 12 (here, three) are arranged side by side in the left-right direction. In addition, each of the three installation spaces 12 is equipped with three through holes 142G constituting an I-type outlet (Outlet). That is, in this embodiment, it is the same as the first modification of embodiment 1. When installing the second unit 2 in the installation space 12, it is not easy to accompany the second unit 2 to the first unit The composition of relative rotation of 1.

根據依本實施態樣的配線器具系統10G，如圖9B所示，可對一個第一單元1裝設複數（此處為三個）第二單元2。其結果，複數（此處為三個）第二單元2會並列配置。在圖9B的例子中，在實施態樣1所說明之複數種類的第二單元2，係以混雜的方式配置。具體而言，作為開關裝置而發揮功能的第二單元206、作為插座而發揮功能的第二單元201、及作為磁鐵插座而發揮功能的第二單元204係並列配置（參照圖5）。According to the wiring appliance system 10G according to this embodiment, as shown in FIG. 9B, a plurality of (here, three) second units 2 can be installed in one first unit 1. As a result, plural (here, three) second units 2 are arranged side by side. In the example of FIG. 9B, the plural types of second units 2 described in Embodiment 1 are arranged in a mixed manner. Specifically, the second unit 206 functioning as a switch device, the second unit 201 functioning as a socket, and the second unit 204 functioning as a magnet socket are arranged side by side (see FIG. 5).

此處，由於第一單元1係共用於複數（此處為三個）第二單元2，因此和針對每個第二單元2設置第一單元1的情況相比，可實現構成之簡化。Here, since the first unit 1 is used for a plurality of (here, three) second units 2, compared with the case where the first unit 1 is provided for each second unit 2, the configuration can be simplified.

又，第一單元1只要具有複數裝設空間12即可，並不限定於如圖9B般，裝設種類彼此不同之複數第二單元2的構成，亦可裝設同一種類的複數第二單元2。再者，裝設空間12的數量並不限定於三個，第一單元1例如亦可具有兩個或是四個以上的裝設空間12。In addition, the first unit 1 only needs to have a plurality of installation spaces 12, and is not limited to the configuration in which a plurality of second units 2 of different installation types are installed as shown in FIG. 9B, and a plurality of second units of the same type may be installed. 2. Furthermore, the number of installation spaces 12 is not limited to three, and the first unit 1 may have two or more installation spaces 12, for example.

再者，複數裝設空間12並不限定於配置成在左右方向上並列於一直線上，例如，亦可配置成在上下方向上並列，亦可配置成排列成L字形。Furthermore, the plural installation spaces 12 are not limited to being arranged in parallel in the left-right direction on a straight line, for example, they may be arranged in parallel in the up-down direction, or arranged in an L-shape.

又，在複數裝設空間12之間，亦可具有分隔部。只要具有分隔部，便可增加鄰接之裝設空間12之間的絕緣距離（漏電距離），例如，在強電系統的第二單元2與弱電系統的第二單元2鄰接的情況下，便不容易產生相互的影響。另一方面，若沒有分隔部，則可使用複數裝設空間12，而裝設一個大型的第二單元2。In addition, a partition may be provided between the plurality of installation spaces 12. As long as there are partitions, the insulation distance (leakage distance) between adjacent installation spaces 12 can be increased. For example, when the second unit 2 of the high-current system is adjacent to the second unit 2 of the weak-current system, it is not easy Produce mutual influence. On the other hand, if there is no partition, a plurality of installation spaces 12 can be used and a large second unit 2 can be installed.

在實施態樣2所說明之構成（包含變形例），可與在實施態樣1所說明之各種構成（包含變形例）適當組合而採用。The configuration (including modification examples) described in Embodiment 2 can be appropriately combined with the various configurations (including modification examples) described in Embodiment 1.

（實施態樣3） 依本實施態樣的配線器具系統10H，如圖10A及圖10B所示，在第一單元1包含於前視觀察下配置於第二單元2之周圍的妝飾板17此點，與依實施態樣1的配線器具系統10不同。以下，針對與實施態樣1相同之構成，係賦予共通的符號而適當省略說明。(Implementation Pattern 3) According to the wiring appliance system 10H of the present embodiment, as shown in FIGS. 10A and 10B, the first unit 1 includes a decorative board 17 arranged around the second unit 2 in front view, which is different from the point that according to the embodiment The wiring appliance system 10 of sample 1 is different. Hereinafter, with respect to the same configuration as that of the first embodiment, the common symbols are assigned, and the description is appropriately omitted.

亦即，在本實施態樣中，如圖10A所示，第一單元1具有妝飾板17。妝飾板17係配置於牆板31的表面側。妝飾板17在前視觀察下，形成為比第二單元2（前板部23）大一圈的略正方形。在本實施態樣中，就一例而言，如圖10B所示，妝飾板17係與***引導部15一體地形成。具體而言，***引導部15係通過施工孔33延伸至牆板31的表面側，而妝飾板17係以從此***引導部15的前端部往側方（上方、下方、左方及右方）伸展的方式一體地形成。That is, in this embodiment, as shown in FIG. 10A, the first unit 1 has a decorative plate 17. The decorative board 17 is arranged on the surface side of the wall board 31. The decorative board 17 is formed in a slightly square shape that is slightly larger than the second unit 2 (front board portion 23) when viewed from the front. In this embodiment, as an example, as shown in FIG. 10B, the decorative plate 17 is formed integrally with the insertion guide 15. Specifically, the insertion guide 15 extends to the surface side of the wall panel 31 through the construction hole 33, and the decorative panel 17 is inserted from the front end of the guide 15 to the side (upper, lower, left, and right) The way of stretching is integrally formed.

依本實施態樣的整個配線器具系統10H在裝設於施工對象物3的狀態下，第一單元1之妝飾板17的背面（後面），係從前方與牆板31中之施工孔33的周邊接觸。再者，在配線器具系統10H中，從牆板31之表面的突出量，第二單元2（前板部23）稍微大於妝飾板17。According to this embodiment of the entire wiring appliance system 10H in the state of being installed on the construction object 3, the back (rear) of the decorative board 17 of the first unit 1 is connected from the front to the construction hole 33 in the wall panel 31 Peripheral contact. Furthermore, in the wiring appliance system 10H, the amount of protrusion from the surface of the wall panel 31 is slightly larger than that of the decorative panel 17 by the second unit 2 (front panel part 23).

藉此，在將配線器具系統10H固定於施工對象物3的狀態下，能以妝飾板17覆蓋住第二單元2的周圍，而使外觀變得良好。With this, in a state where the wiring appliance system 10H is fixed to the construction target 3, the periphery of the second unit 2 can be covered with the decorative panel 17, and the appearance can be improved.

又，妝飾板17的形狀並不限定於略正方形，例如，可採用長方形、三角形或是圓形等適當的形狀。In addition, the shape of the decorative board 17 is not limited to a substantially square shape, and for example, an appropriate shape such as a rectangle, a triangle, or a circle may be adopted.

在實施態樣3所說明之構成（包含變形例），可與在實施態樣1或2所說明之各種構成（包含變形例）適當組合而採用。The configuration (including modification examples) described in Embodiment 3 can be appropriately combined with the various configurations (including modification examples) described in Embodiment 1 or 2 as appropriate.

（實施態樣4） 依本實施態樣的配線器具系統10I，如圖11A~圖11C所示，在具有鎖定部8此點，與依實施態樣1的配線器具系統10不同。以下，針對與實施態樣1相同之構成，係賦予共通的符號而適當省略說明。(Implementation Pattern 4) The wiring appliance system 10I according to the present embodiment is different from the wiring appliance system 10 according to the first embodiment in that it has a locking portion 8 as shown in FIGS. 11A to 11C. Hereinafter, with respect to the same configuration as that of the first embodiment, the common symbols are assigned, and the description is appropriately omitted.

亦即，第一單元1及第二單元2中的至少一者具有鎖定部8。在將第二單元2裝設於裝設空間12的狀態下，鎖定部8可切換「限制從第一單元1取下第二單元2的限制狀態」、及「解除限制的解除狀態」。亦即，鎖定部8至少可切換限制狀態及解除狀態兩種狀態。由於只要鎖定部8處於限制狀態，便會限制從第一單元1取下第二單元2，因此在將第二單元2從第一單元1取下時，必須將鎖定部8設為解除狀態。That is, at least one of the first unit 1 and the second unit 2 has the locking portion 8. In a state where the second unit 2 is installed in the installation space 12, the lock portion 8 can switch between the "restriction state restricting the removal of the second unit 2 from the first unit 1" and the "restriction release state". That is, the lock portion 8 can switch at least two states of the restricted state and the released state. Since the second unit 2 is restricted from being removed from the first unit 1 as long as the lock portion 8 is in the restricted state, when the second unit 2 is removed from the first unit 1, the lock portion 8 must be set to the released state.

在本實施態樣中，如圖11B所示，鎖定部8包含設於第一單元1的鎖定溝81、及設於第二單元2的鎖定銷82。具體而言，鎖定溝81例如係形成於第一單元1之***引導部15之前面的一部分。鎖定銷82係在「將第二單元2之前板部23於前板部23之厚度方向（前後方向）上貫穿」的狀態下，固持於第二單元2。鎖定銷82可在前板部23之厚度方向（前後方向）上，對前板部23相對移動。In this embodiment, as shown in FIG. 11B, the locking portion 8 includes a locking groove 81 provided in the first unit 1 and a locking pin 82 provided in the second unit 2. Specifically, the locking groove 81 is formed, for example, in a part of the front surface of the insertion guide 15 of the first unit 1. The lock pin 82 is fixed to the second unit 2 in a state in which the front plate portion 23 of the second unit 2 is penetrated in the thickness direction (front-rear direction) of the front plate portion 23. The locking pin 82 can relatively move the front plate portion 23 in the thickness direction (front-rear direction) of the front plate portion 23.

亦即，如實施態樣1所說明般，在將第二單元2裝設至第一單元1時，至少伴隨第二單元2對第一單元1的相對旋轉。又，如圖11A所示，只要在將第二單元2裝設於第一單元1的狀態下，限制第二單元2對第一單元1的相對旋轉，便可限制從第一單元1取下第二單元2。在本實施態樣中，如圖11B所示，未將鎖定銷82***鎖定溝81的狀態係相當於鎖定部8的解除狀態，而如圖11C所示，將鎖定銷82***鎖定溝81的狀態係相當於鎖定部8的限制狀態。簡而言之，由於只要鎖定部8處於限制狀態，鎖定銷82便會嵌入鎖定溝81，藉此限制第二單元2對第一單元1的相對旋轉，因而限制從第一單元1取下第二單元2。That is, as described in Embodiment 1, when the second unit 2 is installed to the first unit 1, at least the relative rotation of the second unit 2 to the first unit 1 is accompanied. In addition, as shown in FIG. 11A, as long as the second unit 2 is installed in the first unit 1 and the relative rotation of the second unit 2 to the first unit 1 is restricted, the removal from the first unit 1 can be restricted. The second unit 2. In this embodiment, as shown in FIG. 11B, the state where the lock pin 82 is not inserted into the lock groove 81 corresponds to the released state of the lock portion 8. As shown in FIG. 11C, the lock pin 82 is inserted into the lock groove 81 The state corresponds to the restricted state of the lock portion 8. In short, as long as the locking portion 8 is in a restricted state, the locking pin 82 will fit into the locking groove 81, thereby restricting the relative rotation of the second unit 2 to the first unit 1, thereby restricting the removal of the first unit 1 from the first unit 1. Two unit 2.

又，在本實施態樣中，係於鎖定溝81內設有開關83。開關83係用於控制（導通/斷開）從第一單元1對第二單元2之供電的開關。具體而言，開關83係瞬時型的常開型按扭開關，僅在開關83導通的期間，進行從第一單元1對第二單元2的供電。因此，僅在鎖定銷82***鎖定溝81的限制狀態下，開關83會被鎖定銷82按壓而導通，並進行從第一單元1對第二單元2的供電。另一方面，若鎖定部8處於解除狀態，則由於開關83會處於斷開狀態，故從第一單元1對第二單元2的供電會停止。Moreover, in this embodiment, a switch 83 is provided in the locking groove 81. The switch 83 is a switch for controlling (turning on/off) the power supply from the first unit 1 to the second unit 2. Specifically, the switch 83 is a momentary, normally-open push switch, and power is supplied from the first unit 1 to the second unit 2 only while the switch 83 is on. Therefore, only in the restricted state where the lock pin 82 is inserted into the lock groove 81, the switch 83 is pressed by the lock pin 82 to be turned on, and power is supplied from the first unit 1 to the second unit 2. On the other hand, if the lock portion 8 is in the released state, since the switch 83 is in the off state, the power supply from the first unit 1 to the second unit 2 is stopped.

簡而言之，在本實施態樣中，由於若鎖定部8從限制狀態切換至解除狀態，則從第一單元1對第二單元2的供電會自動停止，故無法在持續從第一單元1對第二單元2供電的同時，將鎖定部8設為解除狀態。換言之，在從第一單元1對第二單元2供電的狀態下，鎖定部8從限制狀態到解除狀態的切換係受到限制。藉此，在從第一單元1對第二單元2供電的狀態下，可防止因將第二單元2從第一單元1取下而產生之問題。In short, in this embodiment, if the locking portion 8 is switched from the restricted state to the released state, the power supply from the first unit 1 to the second unit 2 will be automatically stopped, so it is impossible to continue from the first unit While supplying power to the second unit 2, the lock portion 8 is set to the released state. In other words, in the state where the power is supplied from the first unit 1 to the second unit 2, the switching system of the lock portion 8 from the restricted state to the released state is restricted. Thereby, in the state where the power is supplied from the first unit 1 to the second unit 2, problems caused by removing the second unit 2 from the first unit 1 can be prevented.

又，只要第一單元1及第二單元2中之至少一者具有鎖定部8即可，例如，亦可僅在第一單元1（或是第二單元2）設置鎖定部8。Moreover, as long as at least one of the first unit 1 and the second unit 2 has the locking part 8, for example, the locking part 8 may be provided only in the first unit 1 (or the second unit 2 ).

又，鎖定部8在從第一單元1對第二單元2供電的狀態下，從限制狀態到解除狀態的切換受到限制此點，對配線器具系統10I而言並非必須之構成。亦即，鎖定部8亦可在從第一單元1對第二單元2供電的狀態下，從限制狀態切換成解除狀態。In addition, the switch 8 from the restricted state to the released state is restricted when the power is supplied from the first unit 1 to the second unit 2, which is not an essential configuration for the wiring appliance system 10I. That is, the lock portion 8 may be switched from the restricted state to the released state in a state where the power is supplied from the first unit 1 to the second unit 2.

在實施態樣4所說明之構成（包含變形例），可與實施態樣1~3所說明之各種構成（包含變形例）適當組合而採用。The configuration (including modification examples) described in Embodiment 4 can be appropriately combined with the various configurations (including modification examples) described in Embodiments 1 to 3.

（實施態樣5） 依本實施態樣的配線器具系統10J，如圖12A~圖12C所示，在第一單元1具有複數用於電性連接第二單元2的連接部18此點，與依實施態樣1的配線器具系統10不同。以下，針對與實施態樣1相同之構成，係賦予共通的符號而適當省略說明。在圖12A~圖12C中，係以假想線（兩點鎖線）顯示裝設於第一單元1之狀態的第二單元2。再者，在圖12B及圖12C中，係示意地顯示***連接部18之連接端子24等。(Implementation Pattern 5) According to the wiring appliance system 10J of the present embodiment, as shown in FIGS. 12A to 12C, the first unit 1 has a plurality of connecting parts 18 for electrically connecting the second unit 2, which is different from that according to the embodiment 1. The wiring appliance system 10 is different. Hereinafter, with respect to the same configuration as that of the first embodiment, the common symbols are assigned, and the description is appropriately omitted. In FIGS. 12A to 12C, the second unit 2 installed in the first unit 1 is shown by an imaginary line (two-point lock line). Furthermore, in FIGS. 12B and 12C, the connecting terminal 24 inserted into the connecting portion 18 and the like are schematically shown.

本發明所謂的「連接部」，係意指用於電性連接第二單元2之構成，在實施態樣1中，內蓋體14的一對貫穿孔142、及電力接收部11的一對連接口111均包含於連接部。在本實施態樣中，如圖12A所示，第一單元1包含：構成A、C兼用型插座（Outlet）的一對第一連接口181、及構成I型插座的三個第二連接口182。又，該等一對第一連接口181及三個第二連接口182係分別構成連接部18。換言之，第一單元1包含：由一對第一連接口181所構成連接部18、及由三個第二連接口182所構成的連接部18。The so-called "connecting portion" in the present invention refers to a structure for electrically connecting the second unit 2. In Embodiment 1, a pair of through holes 142 of the inner cover 14 and a pair of the power receiving portion 11 The connection ports 111 are all included in the connection part. In this embodiment, as shown in FIG. 12A, the first unit 1 includes: a pair of first connection ports 181 constituting an A and C dual-use outlet (Outlet), and three second connection ports constituting an I-type socket 182. In addition, the pair of first connection ports 181 and the three second connection ports 182 respectively constitute the connection portion 18. In other words, the first unit 1 includes a connecting portion 18 formed by a pair of first connecting ports 181 and a connecting portion 18 formed by three second connecting ports 182.

在本實施態樣中，該等複數（此處為兩個）連接部18，係配置於一個裝設空間12。具體而言，該等兩個連接部18，係在裝設空間12中，於上下方向上並列配置。In this embodiment, the plural (here, two) connecting portions 18 are arranged in one installation space 12. Specifically, the two connecting portions 18 are arranged in the installation space 12 side by side in the vertical direction.

再者，該等複數（此處為兩個）連接部18，包含種類彼此不同的第一連接部及第二連接部。在本實施態樣中，由一對第一連接口181所構成的連接部18為「第一連接部」，而由三個第二連接口182所構成的連接部18為「第二連接部」。亦即，配置於一個裝設空間12的複數（此處為兩個）連接部18，種類彼此不同。本發明所謂連接部18的「種類」，例如包含插座的類型、是否為USB、及強電/弱電系統等。亦即，在本實施態樣中，由於第一連接部18為A、C兼用型插座，而第二連接部18為I型插座，故兩者係種類彼此不同。Furthermore, the plural (here, two) connecting portions 18 include first connecting portions and second connecting portions of different types. In this embodiment, the connecting portion 18 constituted by a pair of first connecting ports 181 is the "first connecting portion", and the connecting portion 18 constituted by three second connecting ports 182 is the "second connecting portion". ". That is, the plural (here, two) connection parts 18 arranged in one installation space 12 are of different types. The "type" of the connection part 18 in the present invention includes, for example, the type of socket, whether it is USB, and the strong/light current system. That is, in this embodiment, since the first connecting portion 18 is a socket for both A and C, and the second connecting portion 18 is an I-type socket, the two types are different from each other.

藉此，根據裝設於第一單元1的第二單元2之種類，僅將複數（此處為兩個）連接部18中的任一者，為了電性連接第二單元2而使用。例如，如圖12B所示，將使用第一連接部18之第二單元2裝設於第一單元1時，此第二單元2的連接端子24僅***複數連接部18中的第一連接部18（一對第一連接口181）。因此，在圖12B的例子中，第二連接部18（三個第二連接口182）並未使用。Therefore, according to the type of the second unit 2 installed in the first unit 1, only any one of the plurality (here, two) of the connection parts 18 is used for electrically connecting the second unit 2. For example, as shown in FIG. 12B, when the second unit 2 using the first connecting portion 18 is installed in the first unit 1, the connecting terminal 24 of the second unit 2 is only inserted into the first connecting portion of the plurality of connecting portions 18. 18 (a pair of first connection ports 181). Therefore, in the example of FIG. 12B, the second connection portion 18 (three second connection ports 182) is not used.

在依本實施態樣的配線器具系統10J中，可使用如此之未使用的連接部18，而以機械的方式固持第二單元2。亦即，在本實施態樣中，複數連接部18中的一部分供電用之連接部18，係對裝設於裝設空間12的第二單元2供電。又，複數連接部18中的供電用之連接部18以外的一個以上之連接部18，係將裝設於裝設空間12的第二單元2以機械的方式固持。In the wiring appliance system 10J according to this embodiment, such an unused connection part 18 can be used to hold the second unit 2 mechanically. That is, in the present embodiment, a part of the connection parts 18 for power supply among the plurality of connection parts 18 is to supply power to the second unit 2 installed in the installation space 12. In addition, one or more connecting portions 18 other than the connecting portion 18 for power supply among the plurality of connecting portions 18 mechanically hold the second unit 2 installed in the installation space 12.

就一例而言，如圖12C所示，假設係在第一單元1裝設「將第二連接部18作為供電用之連接部18而使用之第二單元2」的情況。此情況下，第二單元2的連接端子24會***複數連接部18中之供電用的第二連接部18（三個第二連接口182）。另一方面，供電用之連接部18以外的連接部18，亦即第一連接部18（一對第一連接口181）係用於機械固持第二單元2。具體而言，第二單元2除了連接端子24之外，亦具有虛設端子29，並將此虛設端子29***第一連接部18（一對第一連接口181）。由於虛設端子29單純用於機械固持第二單元2，故與第二單元2之功能部21電性隔離。虛設端子29亦能以電性絕緣材料形成。As an example, as shown in FIG. 12C, it is assumed that "the second unit 2 using the second connection portion 18 as the connection portion 18 for power supply" is installed in the first unit 1. In this case, the connection terminals 24 of the second unit 2 are inserted into the second connection portions 18 (three second connection ports 182) for power supply in the plurality of connection portions 18. On the other hand, the connecting portion 18 other than the connecting portion 18 for power supply, that is, the first connecting portion 18 (a pair of first connecting ports 181) is used to mechanically hold the second unit 2. Specifically, in addition to the connection terminal 24, the second unit 2 also has a dummy terminal 29, and the dummy terminal 29 is inserted into the first connection portion 18 (a pair of first connection ports 181). Since the dummy terminal 29 is only used for mechanically holding the second unit 2, it is electrically isolated from the functional part 21 of the second unit 2. The dummy terminal 29 can also be formed of an electrically insulating material.

如此，藉由使用未作為供電用使用的連接部18，以機械的方式固持第二單元2，可提高藉由第一單元1固持第二單元2的強度。In this way, by using the connecting portion 18 not used for power supply to mechanically hold the second unit 2, the strength of holding the second unit 2 by the first unit 1 can be improved.

又，根據第二單元2，亦可將複數連接部18均作為供電用而使用。Moreover, according to the second unit 2, all of the plurality of connection parts 18 can be used for power supply.
