[0009] (Embodiment) Hereinafter, with reference to the accompanying drawings, the wiring device 100 according to the embodiment will be described.

In the front view direction, the front side may be referred to as the front, and the back side may be referred to as the back. In the top view direction, the upper surface side may be referred to as the top, and the bottom surface side may be referred to as the bottom.

Figure 1 It is a perspective view of the wiring device 100 observed from the front. Figure 2 It is a perspective view of the wiring device 100 observed from the back. Figure 3 It is a perspective view of the wiring device 100 after a part (the first housing C1) of the housing C is omitted and observed from the back. Figure 4 It is a perspective view of the second housing C2 observed from above.

[0010] (Wiring device) The wiring device 100 according to the embodiment has a function of converting an AC voltage into a DC voltage and connecting to an external electronic device (not shown) such as a smartphone. The wiring device 100 is, for example, a single-port type USB socket (converter) having a single connector 40 and is used in a state of being connected to an AC power supply wiring q (refer to Figure 2 ) as the indoor wiring and being buried in the wall. The wiring device 100 may also be a so-called fast charger.

[0011] As Figures 1 to 3As shown, the wiring device 100 includes: a main substrate 10 on which electronic components B are mounted; a connector 20 that is connected to an external electronic device (not shown); a power supply terminal 30 that is connected to an AC power supply wiring q which is indoor wiring; and a housing C that houses the main substrate 10 on which the connector 20 and the power supply terminal 30 are mounted. Thereby, the electronic components B, the connector 20, the power supply terminal 30, and the main substrate 10 are simply housed in the housing C to assemble the wiring device 100. In addition, the AC power supply wiring q and the external electronic device can be connected via the wiring device 100.

[0012] As Figure 1 shown, the connector 20 protrudes from an opening K provided in the housing C to the front surface f of the wiring device 100. Thereby, when the connector 20 is a receptacle (female side), by inserting a plug (male side) connected to an external electronic device (such as a smartphone) into the connector 20 from the outside of the wiring device 100, the external electronic device can be connected to the wiring device 100 via the connector 20.

[0013] As Figure 2 shown, on the back surface r of the wiring device 100, there is provided an insertion port W for connecting the AC power supply wiring q which is indoor wiring to the power supply terminal 30 (not shown) housed in the housing C. Thereby, by inserting the AC power supply wiring q into the insertion port W from the outside of the wiring device 100, as Figure 14 shown, the AC power supply wiring q can be connected to the wiring device 100 via the power supply terminal 30. In addition, in a state where the wall surface of the living room and the front surface f of the wiring device 100 are held to be in the same plane, the wiring device 100 with the connector 20 exposed to the front surface f can be buried in the wall of the living room or the like for installation.

[0014] As Figure 3 shown, the main substrate 10 mounts the electronic components B. The main substrate 10 is a plate-shaped insulator with conductors wired thereon. The main substrate 10 is configured to be substantially parallel to the bottom surface (or the upper surface) of the wiring device 100, that is, the bottom surface of the second housing C2 of the housing C (or the upper surface of the first housing). The main substrate 10 is supported by the second housing C2 that forms the bottom surface of the wiring device 100.

[0015] Preferably, the main substrate 10 is a multi-layer substrate having a structure of four or more layers. In addition, the number of layers can also be one, two, sixteen, or thirty-two. Thereby, the electronic components B can be arranged with high precision. As a result, the wiring device 100 can be made compact.

[0016] The connector 20 is a device for connecting a computer and a peripheral device. The connector 20 can also be, for example, a serial bus standard capable of information communication or power supply between the computer and the peripheral device. The connector 20 can also be a jack member of USB Type-C having an insertion port for inserting a plug of USB Type-C. The connector 20 is not limited to USB Type-C and can also be standards such as Lightning, USB Type-A, USB Type-B, USB-PD (USB Power Delivery: power transmission protocol), etc. The connector 20 can be a jack member (socket hole) or a plug. When the connector 20 is a jack member, it is a flat hollow cylindrical body centered on an imaginary axis along the plug insertion direction P (refer to Figure 1 ). The connector 20 can also be mounted on the main board 10 or on a connector mounting board different from the main board 10.

[0017] As Figures 1 to 3 shown, the housing C has an outer surface in a substantially rectangular parallelepiped shape and an inner surface forming a space inside in a substantially rectangular parallelepiped shape.

[0018] The housing C has: a first housing C1 that covers the main board 10; and a second housing C2 that engages with the first housing C1 and supports the main board 10. In this way, the housing C is divided into multiple parts, and the main board 10 is supported on one of them. Therefore, the assemblability of the wiring device 100 can be improved.

[0019] The housing C can also include a third housing C3 that has an opening K through which the connector 20 is exposed and forms the front surface f of the wiring device 100.

[0020] The lower end portion of the first housing C1 engages with the upper end portion of the second housing C2. The front portions of the first housing C1 and the second housing C2 respectively engage with the third housing C3. Thereby, the housing C covers and houses the group of electronic components B. In addition, the engaging structure can be, for example, a snap fit.

[0021] As Figure 5 shown, the first housing C1 forms the upper surface, the upper portion of the back surface r, and the upper portions of the two side surfaces S of the wiring device 100. The first housing C1 covers the upper portion of the group of electronic components B including the main board 10 housed in the wiring device 100.

[0022] As Figure 4As shown, the second housing C2 forms the lower surface, the lower part of the back surface r, and the lower parts of the both side surfaces S in the wiring device 100. The second housing C2 covers the lower parts of the group of electronic components B including the main substrate 10 housed in the wiring device 100.

[0023] The third housing C3 forms the front surface f, the front part of the upper surface, the front part of the bottom surface, and the front parts of the both side surfaces S in the wiring device 100. The third housing C3 covers the front part of the group of electronic components B including the main substrate 10 housed in the wiring device 100. The third housing C3 has an opening K for exposing a part of the connector 20 to the outside of the wiring device 100. Preferably, the opening K is arranged at the center of the front surface f of the housing C.

[0024] The wiring device 100 may also appropriately include a clip member C4 for holding the state in which the first housing C1, the second housing C2, and the third housing C3 are assembled. The clip member C4 is arranged so as to cover the outer surfaces of the first housing C1, the second housing C2, and the third housing C3 respectively, and is fixed to the first housing C1 and the second housing C2. The clip member C4 may be substantially U-shaped. The clip member C4 may also be provided at both side portions of the housing C.

[0025] Next, the first housing C1 will be described. Figure 5 FIG. is a perspective view of the first housing C1 as viewed from below. Figure 6 FIG. is a bottom view of the accommodation space A accommodating the release button 60 as viewed from below. In addition, in Figure 6 the illustration of the main substrate 10 and the insulating member 50 is omitted. Figure 7 FIG. is a perspective view of the first housing C1 and the insulating member 50 as viewed from below. Figure 8 FIG. is a perspective view of the insulating member 50 in a state of being engaged with the insulating member guide 42 of the surrounding wall 41 as viewed from below. Figure 9 FIG. is a perspective view of the insulating member 50 in a state of being engaged with the insulating member guide 42 of the surrounding wall 41 and being accommodated in the accommodation space A as viewed from below.

[0026] As Figures 5 to 9 shown, the first housing C1 includes a surrounding wall 41 surrounding the power supply terminals 30. The surrounding wall 41 forms an accommodation space A for accommodating the insulating member 50 disposed between the different poles of the power supply terminals 30. In addition, the first housing C1 has an insulating member guide 42 for supporting the insulating member 50 to slide freely in the accommodation space A.

[0027] As Figure 7 shown, the insulating member 50 has an overall shape of substantially T-shaped. The insulating member 50 has: a guide rail 51 that is engaged to be freely slidable with respect to an insulating member guide 42 formed in the accommodation space A of the first housing C1; an insulating portion 52 that is disposed between opposite poles of the power supply terminal 30; and a through hole 53 through which the AC power wiring q can be inserted. The guide rail 51 is a linear rail. The guide rail 51 may also be formed in a portion extending in the lateral direction from one end portion of the insulating portion 52. A pair of guide rails 51 are provided on the insulating member 50 so as to be separated in the lateral direction. The insulating portion 52 is, for example, rod-shaped and has a size (width in the lateral direction) slightly smaller than the distance between opposite poles of the power supply terminal 30. The through hole 53 is, for example, circular in shape, and a pair of through holes 53 are provided on the insulating member 50 so as to be separated in the lateral direction. The through hole 53 may also be formed in a portion extending in the lateral direction from one end portion of the insulating portion 52. As Figure 3 shown, the insulating member 50 is accommodated in the accommodation space A in a state where the guide rail 51 is engaged with the insulating member guide 42, the insulating portion 52 extends in the front surface direction, and the through hole 53 faces the front direction. Thereby, the insulating portion 52 of the insulating member 50 can be appropriately disposed between opposite poles of the power supply terminal 30.

[0028] As Figure 6 shown, the surrounding wall 41 may also include: a first surrounding wall 411 that extends downward from the upper surface of the first housing C1 substantially parallel to the side surface S of the first housing C1; and a second surrounding wall 412 that extends downward from the upper surface of the second housing C2 substantially parallel to the back surface r of the first housing C1. The accommodation space A surrounded by the inner surface i of the upper wall of the first housing C1, the first surrounding wall 411, the second surrounding wall 412, the side wall having the side surface S, the back wall having the back surface r, and the main substrate 10 has a size capable of accommodating the power supply terminal 30, the insulating member 50, and the release button 60. The accommodation space A is, for example, rectangular parallelepiped-shaped.

[0029] The insulating member guide 42 is a linear groove along the vertical direction (Z direction) of the first housing C1. For example, if there are two guide rails 51, the insulating member guide 42 is provided at two positions in the accommodation space A according to the number of guide rails 51 of the insulating member 50. The insulating member guide 42 is provided at positions facing each other at each of the first surrounding wall 411 and the side wall having the side surface S, at positions corresponding to the interval between the pair of guide rails 51 formed on the insulating member 50.

[0030] The insulating member guide 42 engages the guide rail 51 of the insulating member 50 and supports the insulating member 50 to be freely slidable. Thereby, as Figure 6 andFigure 7 As shown, after the release button 60 is inserted into the release button guide 43 and housed in the housing space A formed inside the surrounding wall 41, as Figure 8 shown, the rail 51 of the insulating member 50 is inserted into the groove of the insulating member guide 42, and the insulating member 50 is pressed upward (inside the housing space A), so that as Figure 9 shown, the insulating member 50 can be housed in the housing space A. Then, the release button 60 and the insulating member 50 can be housed in the housing space A while maintaining their postures.

[0031] In this way, the first housing C1 includes a surrounding wall 41 that surrounds the power supply terminal 30. The surrounding wall 41 forms a housing space A for housing the insulating member 50 disposed between the different poles of the power supply terminal 30. In addition, the first housing C1 has an insulating member guide 42 in the housing space A that supports the insulating member 50 to slide freely. Thereby, it is possible to be fixed together with the first housing C1 while maintaining the postures of the release button 60 and the insulating member 50. Therefore, the release button 60 and the insulating member 50 can be easily inserted into the first housing C1. In addition, the posture of the insulating member 50 supported by the insulating member guide 42 can be maintained while the release button 60 is in a state of being nailed between the inner surface i of the upper wall of the surrounding wall 41 and the insulating member 50. Therefore, by assembling the second housing C2 including the main substrate 10 on which the power supply terminal 30 is mounted and the first housing C1 that houses the insulating member 50, it is possible to naturally be in a state of being nailed between the inner surface i of the upper wall of the surrounding wall 41 and the insulating member 50, and the insulating member 50 can be disposed between the different poles of the power supply terminal 30, thereby reliably ensuring the safety distance between the different poles and performing insulation. Thus, there is no need for a high-precision operation to prevent the release button 60 and the insulating member 50 from falling off during assembly, and there is no need to maintain the posture of the housing C in order to separately and independently dispose the release button 60 and the insulating member 50 between the different poles of the power supply terminal 30. Therefore, the assembly workability and quality of the wiring appliance 100 can be improved. Therefore, the component parts can be reasonably arranged and housed in the housing C, thereby providing a compact wiring appliance 100 with high organization.

[0032] Specifically, as Figure 6 shown, the housing space A houses the release button 60, and the release button 60 can disconnect the AC power wiring q that acts on the power supply terminal 30 and is connected to the power supply terminal 30 from the power supply terminal 30. The first housing C1 has a release button guide 43 in the housing space A that restricts the lateral movement of the release button 60 and guides it to move freely longitudinally. In addition, the release button 60 is disposed between the first housing C1 and the insulating member 50 (not shown in Figure 6 ).

[0033] The release button 60 has a terminal acting portion 61 which has the function of deforming or moving the terminal spring 32 of the power supply terminal 30 (refer to Figure 10 ) by pressing it, thereby disconnecting the connection between the AC power supply wiring q and the terminal spring 32; and a tool acting portion 62 which is pressed by a tool or the like from the outside of the wiring device 100. The terminal acting portion 61 is disposed at a position overlapping the upper side of the terminal spring 32. The tool acting portion 62 is disposed at a position not overlapping the upper side of the terminal spring 32. The lateral movement of the tool acting portion 62 is restricted by the release button guide 43 and is supported to be freely movable longitudinally.

[0034] Next, the operation of the release button 60 will be described. As Figure 2 shown, when, in a state where the wiring device 100 is assembled, the tool acting portion 62 is pressed by a tool or the like from the outside of the wiring device 100 through the wiring connection / disconnection hole H formed in the back surface r, the release button 60 tilts or further moves the terminal acting portion 61 of the release button 60 downward. In this way, the terminal spring 32 is pressed downward by the terminal acting portion 61 and thus deforms or moves downward. Thereby, the wiring cutting groove SL (refer to Figure 10 , Figure 14 and Figure 15 ) becomes larger, and the terminal spring 32 separates from the AC power supply wiring q. In this way, the release button 60 is configured to be able to disengage the AC power supply wiring q clamped between the terminal spring 32 and the terminal housing 31 from the power supply terminal 30.

[0035] In this way, the lateral movement of the release button 60 is restricted by the release button guide 43 formed in the accommodation space A of the first housing C1, and the longitudinal movement is supported in a free state. Thereby, before the assembly of the housing C, the release button 60 can be appropriately disposed and accommodated in the accommodation space A of the first housing C1. In addition, after the assembly of the housing C, by operating the release button 60 from the outside of the wiring device 100, the terminal spring 32 is moved downward in the longitudinal direction, and the AC power supply wiring q can be accurately disengaged from the power supply terminal 30.

[0036] (Power supply terminal) Next, the power supply terminal 30 will be described. Figure 12 FIG. is a perspective view of the power supply terminal 30 as viewed from below. Figure 13 FIG. is a perspective view of the main substrate 10 as viewed from above. Figure 14 FIG. is a perspective view of the power supply terminal 30 and the AC power supply wiring q in the connected state as viewed from above. Figure 15This is a cross-sectional view of the power supply terminal 30 and the AC power supply wiring q observed in the horizontal direction in the connected state. As Figure 12 and Figure 15 shown, the power supply terminal 30 has: a terminal spring 32; a terminal housing 31 which includes a terminal pin 33 installed in a manner of being inserted into the main substrate 10 and holds the terminal spring 32; a wiring slot SL formed between the terminal spring 32 and the terminal housing 31 and through which the AC power supply wiring q is inserted. In addition, the wiring slot SL opens in a wiring direction E that intersects with the insertion direction a of the terminal pin 33 into the main substrate 10. In this way, the wiring slot SL through which the AC power supply wiring q is inserted opens in the wiring direction E of the AC power supply wiring q that intersects with the insertion direction a of the terminal pin 33 into the main substrate 10. Therefore, the insertion direction a of the terminal pin 33 and the axial direction of the AC power supply wiring q intersect. Therefore, even assuming that the AC power supply wiring q is stretched along the wiring direction E, since the direction of the tensile force acting on the power supply terminal 30 via the AC power supply wiring q and the direction in which the terminal pin 33 drops are not the same, it is possible to make it difficult for the terminal pin 33 to drop from the main substrate 10. In addition, compared with the case where the wiring direction E of the AC power supply wiring q is along the insertion direction a of the terminal pin 33, the distance M from the connection position between the main substrate 10 and the terminal pin 33 to the action point of the tensile force acting on the AC power supply wiring q can be made shorter, so that the torque acting on the power supply terminal 30 can be reduced. Thus, there is no need to mount the power supply terminal 30 on the main substrate 10 by screwing, and even when mounted by welding or the like, it is difficult for the power supply terminal 30 to separate from the main substrate 10.

[0037] Specifically, preferably, the terminal pin 33 has a spring structure that is mounted on the main substrate 10 by snap fit. Specifically, as Figure 12 shown, the terminal pin 33 is divided into two at the tip in a manner of elastically flexing when inserted into the terminal slot 11 formed in the main substrate 10 (refer to Figure 13 ). The terminal pin 33 flexes inward when inserted into the terminal slot 11 formed in the main substrate 10 (refer to Figure 13 ) and elastically returns after insertion and is fixed in the terminal slot 11. Thereby, the power supply terminal 30 can be mounted on the main substrate 10 with high precision and simply without screwing or welding. In addition, the terminal pin 33 can also be mounted on the main substrate 10 by welding in a state where the spring structure mounted by snap fit is inserted through the main substrate 10. In addition, the terminal pin 33 may not have a spring structure that is mounted on the main substrate 10 by snap fit. In addition, the terminal pin 33 without the spring structure mounted by snap fit can also be mounted by welding in a state where it is inserted through the main substrate 10.

[0038] As Figure 12 shown, the terminal housing 31 has a bottom surface 34 shaped along the wiring direction E through which the AC power wiring q is inserted. As Figure 12 shown, the bottom surface 34 of the terminal housing 31 is, for example, substantially rectangular and makes surface contact with the contact surface 12 of the main substrate 10 (see Figure 13 ). Thereby, heat generated in the power terminal 30 can be efficiently exhausted via the main substrate 10, and the power terminal 30 can be fixed with high precision and firmly without tilting with respect to the main substrate 10.

[0039] (Housing C) Next, the housing C will be described. Figure 10 FIG. is a perspective view of the second housing C2 that supports the main substrate 10 on which the power terminal 30 is mounted, as viewed from above. Figure 11 FIG. is a perspective view of the power terminal 30 and the insulating member 50 mounted on the main substrate 10, as viewed from above.

[0040] As Figure 2 shown, the housing C has a ground-side insertion port W1 through which the ground-side wiring q1 of the AC power wiring q is inserted, and a non-ground-side insertion port W2 through which the non-ground-side wiring q2 of the AC power wiring q is inserted. Further, the ground-side insertion port W1 and the non-ground-side insertion port W2 are arranged substantially parallel to the main substrate 10. Thereby, the ground-side insertion port W1 and the non-ground-side insertion port W2 can be arranged side by side in the horizontal direction. Thus, when the wiring device 100 is inserted into a socket box provided in a wall of a general residence, the AC power wiring q in the socket box can be wound and connected to the wiring device 100 without being twisted. In addition, the different poles of the power terminal 30, the ground-side insertion port W1, and the non-ground-side insertion port W2 are also arranged substantially parallel to the main substrate 10, so that the AC power wiring q inserted into the wiring device 100 from the outside can be connected to the power terminal 30 without being wound around for a long distance.

[0041] As Figure 4 and Figure 10As shown, the housing C has a partition wall CW that insulates and divides the power supply terminal 30 (primary side) and the DC circuit section (secondary side). Insulation can be achieved through the partition wall CW in a manner that maintains a safety distance between the power supply terminal 30 (primary side) and the DC circuit section (secondary side). Additionally, the rigidity of the housing C can be enhanced by the partition wall CW. Preferably, the partition wall CW extends substantially vertically upward from the inner surface of the bottom wall of the second housing C2. Since the partition wall CW is provided in the housing C, it can be naturally positioned at the appropriate location during assembly. Moreover, since the partition wall CW is provided in the housing C, the risk of forgetting to configure an insulator, such as an insulating seal, between the power supply terminal 30 and the DC circuit section can be eliminated.

[0042] As Figure 10 and Figure 11 shown, the partition wall CW is inserted through a slit 10S provided in the main substrate 10. Thereby, the partition wall CW formed on the second housing C2 that supports the main substrate 10 from below the main substrate 10 can be extended upward through the main substrate 10. As a result, the rigidity of the partition wall CW can be increased, making it difficult to fall down. Additionally, when the main substrate 10 is inserted into the second housing C2, the partition wall CW serves as a guide, so it is easy to position the main substrate 10. Moreover, the safety distance between the power supply terminal 30 and the DC circuit section can be maintained, ensuring reliable insulation.

[0043] (Relationship among the housing, the main substrate, and the transformer substrate) Next, the housing C, the main substrate 10, and the transformer substrate 70 will be described. Figure 15 It is a cross-sectional view of the power supply terminal 30 and the AC power supply wiring q in a connected state as observed from the side. Figure 16 It is a perspective view of the transformer substrate 70 on which the transformer Bt is mounted and the main substrate 10 as observed from above.

[0044] As Figure 15 and Figure 16 shown, the wiring device 100 may also include a transformer substrate 70 that is erected on the main substrate 10 and on which the transformer Bt is mounted. The transformer substrate 70 is mounted on the main substrate 10, for example, by welding, so as to extend in a direction substantially perpendicular to the surface of the main substrate 10. The transformer Bt is provided so as to extend in a direction substantially perpendicular to the surface of the transformer substrate 70. Therefore, the surface of the main substrate 10 and the extending direction of the transformer substrate 70 can be made substantially parallel. Thereby, the extending direction of the transformer Bt can be set to the horizontal direction, and the height of the transformer Bt, which has a relatively large size even among the electronic components B housed in the housing C, can be suppressed, enabling the housing C to be made more compact.

[0045] (concave and convex) Next, the concave and convex portions will be described. Figure 17 It is a perspective view showing the positional relationship between the concave and convex portions CP of the housing C and the transformer Bt.

[0046] As Figure 17 shown, preferably, the housing C has concave and convex portions CP for promoting heat dissipation at a position facing the transformer Bt. The concave and convex portions CP are provided on the inner surface i of the upper wall of the first housing C1. In addition, as Figure 4 shown, the concave and convex portions CP may also be provided at a position corresponding to the lower side of the transformer Bt with the main substrate 10 interposed therebetween on the inner surface of the bottom wall of the second housing C2. Thereby, the surface area of the position in the housing C facing the transformer Bt can be increased, and thus, the heat generated from the transformer Bt can be effectively discharged to the outside of the wiring device 100 via the housing C.

[0047] As Figure 5 and Figure 17 shown, the concave and convex portions CP are formed in a grid pattern. For example, the concave and convex portions CP may be formed by aligning rectangular depressions in the vertical and horizontal directions. Thereby, the concave and convex portions CP can be formed densely on the inner surface i of the housing C facing the transformer Bt to increase the surface area, and thus, the heat generated from the transformer Bt can be further effectively discharged to the outside of the wiring device 100 via the housing C.

[0048] The transformer Bt may also have a sheet-like heat dissipator 80 on its surface. In addition, preferably, the concave and convex portions CP face the heat dissipator 80. The heat dissipator 80 only needs to have high thermal conductivity, and is made of a resin such as silicon, acrylic, or polyurethane, for example. Thereby, the heat generated from the transformer Bt can be dissipated to the concave and convex portions CP via the heat dissipator 80, and thus, it can be further effectively discharged to the outside of the wiring device 100 via the housing C.

[0049] As described above, the wiring device 100 includes: a main substrate 10 on which electronic components B are mounted; a connector 20 that is connected to an external electronic device; a power supply terminal 30 that is connected to an AC power wiring q; and a housing C that houses the main substrate 10 on which the connector 20 and the power supply terminal 30 are mounted. The housing C has: a first housing C1 that covers the main substrate 10; and a second housing C2 that engages with the first housing C1 and supports the main substrate 10. The first housing C1 includes a surrounding wall 41 that surrounds the power supply terminal 30. The surrounding wall 41 forms a housing space A that houses an insulating member 50 disposed between different poles of the power supply terminal 30. Further, the first housing C1 has an insulating member guide 42 in the housing space A that supports the insulating member 50 so as to be freely slidable. Thereby, it is possible to easily insert the release button 60 and the insulating member 50 into the first housing C1. Further, it is possible to maintain the posture of the insulating member 50 supported by the insulating member guide 42 while the release button 60 is in a state of being fixed between the inner surface i of the upper wall of the surrounding wall 41 and the insulating member 50. Therefore, by assembling the second housing C2 including the main substrate 10 on which the power supply terminal 30 is mounted and the first housing C1 that houses the insulating member 50, it is possible to naturally bring it into a state of being fixed between the inner surface i of the upper wall of the surrounding wall 41 and the insulating member 50, and it is possible to dispose the insulating member 50 between different poles of the power supply terminal 30, thereby reliably ensuring the safety distance between different poles and performing insulation. Accordingly, there is no need for an operation with a precision to prevent the release button 60 and the insulating member 50 from falling off during assembly, and there is no need to hold the posture of the housing C in order to separately and independently dispose the release button 60 and the insulating member 50 between different poles of the power supply terminal 30, thereby improving the assembly workability and quality of the wiring device 100. Therefore, the constituent parts can be reasonably arranged and housed in the housing C, thereby providing a compact wiring device 100 with high organization.

[0050] In addition, the technical scope of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention.

[0051] Further, constituent elements in the above-described embodiments can be appropriately replaced with well-known structural elements without departing from the gist of the present invention. In addition, the above-described modified examples can be appropriately combined without departing from the gist of the present invention. Reference Signs
