(Embodiment 1)
(1) Overview First, an overview of the wiring device 1 according to the present embodiment will be described with reference to FIGS. 1 and 2.

  The wiring device 1 according to the present embodiment is an outlet that is connected to a plug of an electric device and supplies electric power to the electric device. Here, as the wiring device 1, a two-port type outlet for an AC 220V with a grounding electrode and capable of connecting two plugs at the same time is illustrated. Moreover, in this embodiment, the indoor wiring device 1 attached to the wall of a building is illustrated as the wiring device 1. The building where the wiring device 1 is installed is, for example, a detached house, an apartment house, an office, a store, a nursing facility, or the like.

  The wiring device 1 is attached to the construction surface 800 (here, the wall surface of the building) in a state where an electric wire is electrically connected to the wiring device 1. In this wiring device 1, the plug or the blade of the plug of the electric device is inserted into the insertion hole 311 formed in the front surface 31, whereby the plug is electrically connected, and power is supplied from the wiring device 1 to the electric device. Is possible. Here, the wiring device 1 is an embedded wiring device, and is attached to the construction surface 800 using the mounting frame 8 (see FIG. 2). The mounting frame 8 has an opening window 81. The attachment frame 8 is attached to the construction surface 800 in a state where the wiring device 1 is attached in the opening window 81. Specifically, the attachment frame 8 is attached to the construction surface 800 by being fixed to the embedded box, for example. The embedding box here is a box-shaped member whose front surface is open, and is installed in the wall so that the front surface is exposed forward from a construction hole formed in the construction surface 800. Thereby, the wiring device 1 is attached to the construction surface 800 in a state in which the front surface 31 is exposed forward and at least a part (rear part) is embedded in the wall (in the embedded box).

  Further, a decorative plate 9 is attached to the attachment frame 8. The decorative plate 9 is made of synthetic resin. The decorative plate 9 has a rectangular frame shape having an opening hole 91. The decorative plate 9 is attached to the attachment frame 8 so as to cover substantially the entire attachment frame 8 from the front surface of the attachment frame 8 to the peripheral surface of the attachment frame 8. On the rear surface of the decorative plate 9, a plurality of (four in the example of FIG. 2) hooking projections 92 protruding rearward are formed. The decorative plate 9 is held by the mounting frame 8 by hooking the plurality of hooking protrusions 92 to the edges of the mounting holes 82 of the mounting frame 8. The opening hole 91 is formed in a rectangular shape according to the shape of the front surface 31 of the wiring device 1. Therefore, even when the decorative plate 9 is attached to the attachment frame 8, the front surface 31 of the wiring device 1 is exposed forward as shown in FIG.

  In the present embodiment, the wiring device system 10 includes the wiring device 1 and a mounting frame 8. That is, the wiring device system 10 includes the wiring device 1 and the mounting frame 8 as components. Furthermore, the decorative plate 9 may or may not be included in the components of the wiring device system 10. Furthermore, the wiring device 1 which comprises the wiring device system 10 with the attachment frame 8 is not restricted to an outlet, For example, a switch etc. may be sufficient.

  By the way, as shown in FIG. 2, the wiring device 1 according to the present embodiment is combined with the body 2 having an opening surface 21 (see FIG. 3) on the front surface and the body 2 so as to cover the opening surface 21 of the body 2. And a cover 3. The body 2 and the cover 3 constitute the container 4 in a state of being combined with each other. The container body 4 stores internal components such as a blade receiving member and a terminal plate. The body 2 and the cover 3 are coupled to each other by a plurality of (here, four) assembly frames 5. In other words, the wiring device 1 includes a container body 4 including a body 2 and a cover 3, and a plurality of assembly frames 5 for coupling the body 2 and the cover 3.

  In the wiring device 1 according to the present embodiment, the cover 3 is configured to be larger than the body 2 in the second direction (left-right direction) orthogonal to the first direction (front-rear direction) in which the body 2 and the cover 3 are combined. ing. In short, the cover 3 is configured to be wider than the body 2 in the second direction. In other words, both end faces 32 (see FIG. 4) of the cover 3 orthogonal to the second direction are located outside the end faces 22 (see FIG. 4) of the body 2 orthogonal to the second direction. Here, both end surfaces 32 of the cover 3 in the second direction are located outside the both end surfaces 22 of the body 2 in the second direction. In the second direction, both end surfaces 32 of the cover 3 are It means that it is outside the both end faces 22 but not between (ie, inside). Thereby, the dimension of the wiring device 1 in the second direction when the wiring device 1 is viewed from the front (front), that is, the area of the front surface 31 of the wiring device 1 can be made larger than that of the body 2. On the other hand, the dimension in the second direction of the body 2 that fits in the wall (inside the embedding box), that is, the area of the rear surface of the wiring device 1 can be reduced compared to the cover 3.

  Therefore, in the wiring device 1, with the wiring device 1 attached to the construction surface 800, the size of the portion that fits in the wall (inside the embedding box) is increased while the size of the portion exposed forward is increased. It can be kept small. The portion exposed to the front of the wiring device 1, that is, the front surface 31, is a portion where the user performs operations (plugging and unplugging in the case of an outlet) when the user uses the wiring device 1, so that the size of this portion should be increased. Thus, the operability and designability of the wiring device 1 are improved. Further, when the wiring device 1 is an outlet, by increasing the size of the front surface 31, the insertion hole 311 formed in the front surface 31, the mounting frame 8 and the decorative plate 9 positioned around the front surface 31 are provided. It also leads to an increase in the insulation distance between In particular, when the decorative plate 9 is made of metal, it is useful to increase the insulation distance between the insertion hole 311 and the decorative plate 9. On the other hand, by reducing the size of the part of the wiring device 1 that fits inside the wall (inside the embedding box), the space around the wiring device 1 in the wall can be afforded, and a space for storing wiring and the like can be provided. It becomes easy to secure.

  In the wiring device 1 according to the present embodiment, the body 2 and the cover 3 having at least different dimensions in the second direction are thus coupled to each other by the plurality of assembly frames 5. A plurality (four here) of assembly frames 5 are attached to both sides of the container body 4 in the second direction in a state where the body 2 and the cover 3 are coupled to each other. In other words, at least a pair of coupling structures for coupling the body 2 and the cover 3 are provided on both sides in the second direction of the container 4 (the body 2 and the cover 3).

  Further, in the wiring device 1 according to the present embodiment, the plurality of assembly frames 5 also serve as the device-side mounting portion 102 (see FIG. 5A) for mounting the wiring device 1 to the mounting frame 8. That is, the wiring device 1 includes at least a pair of device side mounting portions 102 on both sides in the second direction of the container body 4, and each of the at least one pair of device side mounting portions 102 is realized by the assembly frame 5. . The plurality of assembly frames 5 have a pair of second mounting portions 58 (see FIG. 2) as at least a pair of mounting claws protruding from both end surfaces in the second direction of the wiring device 1 (container 4). At least a pair of restriction recesses 832 (see FIG. 2) is formed in the mounting frame 8 at a position corresponding to at least the pair of second mounting portions 58 on the inner surface of the opening window 81. The wiring device 1 is attached to the attachment frame 8 in a state where at least the pair of second attachment portions 58 are inserted into at least the pair of restriction recesses 832.

(2) Details Hereinafter, the wiring device 1 according to the present embodiment will be described in detail.

  In this embodiment, the direction orthogonal to the construction surface 800 in a state where the wiring device 1 is attached to the wall surface of the building that is the construction surface 800 is defined as the “front-rear direction”, and the front surface 31 of the wiring device 1 is directed. The side is described as “front”. Further, a direction that is orthogonal to the front-rear direction and parallel to the horizontal plane will be referred to as “left-right direction”, and the right side when viewing the wiring device 1 from the front will be described as “right”, and the left side as “left”. . Furthermore, the direction perpendicular to both the front-rear direction and the left-right direction, that is, the direction perpendicular (orthogonal) to the horizontal plane is defined as “vertical direction”, and the downward (vertical direction) viewed from the front of the wiring device 1 is defined as “downward”. ". When each direction is defined in this way, the “front-rear direction” corresponds to the “first direction”, the “left-right direction” corresponds to the “second direction”, and the “up-down direction” corresponds to the “third direction”. The arrows indicating “front-rear direction”, “left-right direction”, and “up-down direction” in the drawings are merely shown for the purpose of explanation, and are not accompanied by an entity.

  However, these directions are not intended to limit the use direction of the wiring device 1. For example, when the wiring device 1 is attached to the floor surface instead of the wall surface, the first direction (front-rear direction) is a direction perpendicular to the horizontal plane, and the second direction (left-right direction) and the third direction (up-down direction). Is a direction parallel to the horizontal plane. Further, even when the wiring device 1 is attached to the wall surface, the “left-right direction” is set to the horizontal surface by attaching the wiring device 1 to the wall surface in a direction (ie, horizontal direction) in which the “vertical direction” is parallel to the horizontal surface. The vertical direction.

(2.1) Wiring device First, the structure of the wiring device 1 is demonstrated with reference to FIGS.

  The wiring device 1 includes the body 2, the cover 3, and the assembly frame 5 as described above. The assembly frame 5 is a member for joining the body 2 and the cover 3 together. In the present embodiment, the wiring device 1 includes four assembly frames 5 in order to connect the body 2 and the cover 3 at four locations. Since a plurality of (four here) assembly frames 5 have a common configuration, one assembly frame 5 will be described below unless otherwise specified, and the other assembly frames 5 are described as having the same configuration. Is omitted.

  As shown in FIG. 3, the body 2 is formed in a box shape having an opening surface 21 on one surface (front surface) in the front-rear direction. The opening surface 21 of the body 2 is formed in a rectangular shape that is long in the vertical direction. The cover 3 covers the opening surface 21 of the body 2 by being combined with the body 2 from the front. The cover 3 is formed in a box shape having an opening surface 33 on the surface facing the body 2, that is, the rear surface. Similar to the opening surface 21 of the body 2, the opening surface 33 of the cover 3 is formed in a rectangular shape that is long in the vertical direction. However, in this embodiment, since the cover 3 is configured to be wider than the body 2 in the left-right direction (second direction), the opening surface 33 of the cover 3 is slightly larger in the second direction than the opening surface 21 of the body 2. large. FIG. 3 shows a state in which the body 2 and the cover 3 are separated (disassembled), and the cover 3 in a state of being combined with the body 2 is indicated by an imaginary line (two-dot chain line). In the example of FIG. 3, the central part in the vertical direction of the peripheral wall of the body 2 surrounding the opening surface 21 is formed in a convex shape protruding forward. In accordance with this convex shape, the central part in the vertical direction of the peripheral wall of the cover 3 surrounding the opening surface 33 is formed in a concave shape that is recessed forward.

  The body 2 and the cover 3 constitute a container 4 by being coupled to each other. In this embodiment, the container body 4 is formed in plane symmetry in the left-right direction. The wiring device 1 has a configuration in which internal components such as a blade receiving member and a terminal plate are accommodated in a space formed between the body 2 and the cover 3, that is, an internal space of the container body 4. In short, the wiring device 1 includes a body 4 composed of a body 2 and a cover 3 that are separable from each other, and the body 2 and the assembly frame 5 are used so as to house internal components in the internal space of the body 4. The cover 3 is assembled by being combined. That is, the assembly frame 5 constitutes an assembly member 50 (see FIG. 2) used for assembling the wiring device 1. The instrument body 40 (see FIG. 2) is a part of the wiring instrument 1 and includes a body 2 and a cover 3 that are coupled to each other by an assembly frame 5. The instrument main body 40 includes internal parts in addition to the container body 4 (the body 2 and the cover 3). That is, the wiring device 1 includes the device body 40 and the assembly frame 5. However, illustration of the internal components housed in the container 4 is omitted in all drawings.

  Here, the body 2, the cover 3, and the assembly frame 5 are all made of synthetic resin having electrical insulation. The body 2 and the cover 3 constituting the container 4 that stores the internal parts are made of a thermosetting resin having excellent tracking resistance such as urea resin (urea resin). On the other hand, the assembly frame 5 is made of a thermoplastic resin such as PBT (Polybutylene Terephthalate), ABS resin, or PC (Polycarbonate). If at least one of the body 2 and the cover 3 is made of a thermoplastic resin, a claw is provided on one of the body 2 and the cover 3 and a hole for fitting the claw is provided on the other, so that the body can be formed by a so-called snap fit structure. 2 and cover 3 can be combined. That is, the body 2 and the cover 3 can be coupled by allowing the claws to fit into the holes while elastically deforming either the body 2 or the cover 3. On the other hand, when the body 2 and the cover 3 are made of a thermosetting resin as in the present embodiment, it is difficult to impart sufficient elasticity to the body 2 and the cover 3, and the snap fit as described above. The structure is difficult to adopt. Therefore, in the wiring device 1 according to the present embodiment, the assembly of the body 2 and the cover 3 is realized by employing an assembly frame 5 made of a member different from the body 2 and the cover 3.

  A plurality of insertion holes 311 are formed in the front surface of the cover 3 which is the front surface 31 of the wiring device 1. The plug or the blade of the plug of the electric device is inserted into the plurality of insertion holes 311, whereby the plug is electrically connected to the wiring device 1. Here, as shown in FIG. 2, the wiring device 1 has two sets of three insertion holes 311 so as to be compatible with a plug having a pair of power supply electrodes (L and N poles) and a ground electrode. doing. Each set of insertion holes 311 is formed in a shape suitable for two types of plugs, A type and C type. The three insertion holes 311 of each set are arranged such that a pair of insertion holes 311 corresponding to the pair of power supply electrodes are arranged in the left-right direction, and an insertion hole 311 corresponding to the grounding electrode is positioned above the insertion holes 311. Further, the two sets of insertion holes 311 are arranged side by side in the vertical direction.

  As shown in FIG. 4, a terminal hole 231 for connecting an electric wire (wiring) is formed on the rear surface of the container body 4 serving as the rear surface 23 of the wiring device 1. A terminal portion including a terminal plate and the like is accommodated in a position corresponding to the terminal hole 231 in the container body 4. The terminal portion is a so-called quick connection terminal of a wire insertion type to which an electric wire is connected by inserting the electric wire from the terminal hole 231. In the present embodiment, a total of three electric wires including a pair of power supply lines and a ground line (ground line) are connected to the wiring device 1. Furthermore, the wiring device 1 has a feed terminal for feed wiring, and can connect up to six electric wires to the terminal portion. On the side of the terminal hole 231 on the rear surface of the wiring device 1, a release operation hole 232 for inserting the tip of a jig such as a driver is formed. By inserting a jig such as a driver from the release operation hole 232, the holding state of the electric wire in the terminal portion is released.

  As shown in FIG. 4, the wiring device 1 according to the present embodiment is configured such that the cover 3 is larger than the body 2 in the left-right direction, that is, the cover 3 is configured wider. In the vertical direction, the body 2 and the cover 3 have substantially the same dimensions. FIG. 4 is a rear view of the wiring device 1 in a state where the assembly frame 5 is separated from the container body 4 (the body 2 and the cover 3), as viewed from the rear, and the shaded area is the cover 3. Represents.

  That is, as shown in FIG. 4, the distance between the left and right end faces 32 (left end face and right end face) of the cover 3 is larger than the distance L1 between the left and right end faces 22 (left end face and right end face) of the body 2. The distance L2 is set large (L1 <L2). Furthermore, in the present embodiment, the container body 4 is plane-symmetric in the left-right direction, so that the left and right end faces 32 of the cover 3 protrude from the left and right end faces 22 of the body 2. 32 is located outside the both end faces 22 of the body 2. In other words, a step is generated between the one end surface 32 of the cover 3 and the one end surface 22 of the body 2. Since the container body 4 is symmetrical in the left-right direction, the distance from the one end surface 32 of the cover 3 to the one end surface 22 of the body 2 is represented by “(L2−L1) / 2”. Thereby, when the wiring device 1 is viewed from the rear, the rear surface of the cover 3 is exposed at least from both sides of the body 2 in the second direction.

  By the way, the assembly frame 5 has a first projecting portion 34 formed on the cover 3 and a second projecting portion 24 formed on the body 2, and a coupling structure 101 for coupling the body 2 and the cover 3 (see FIG. 4). ). In other words, the coupling structure 101 includes one assembly frame 5, the first protrusion 34 of the cover 3, and the second protrusion 24 of the body 2.

  At least a pair of coupling structures 101 are provided on both sides of the body 2 and the cover 3 in the left-right direction. In the present embodiment, two pairs (two sets) of coupling structures 101 are provided on both end surfaces (left end surface and right end surface) in the left-right direction of the container body 4. The two pairs of coupling structures 101 are provided at the four corners of the container body 4 when viewed from the front so as to be arranged in the vertical direction on each end face (left end face or right end face) in the left-right direction of the container body 4. Therefore, the body 2 and the cover 3 are joined at the four corners of the container 4 as seen from the front.

  Specifically, the cover 3 includes a first protrusion 34 that protrudes from one end surface 32 (left end surface or right end surface) of the cover 3 in the left-right direction. Similarly, the body 2 includes a second protrusion 24 that protrudes from one end surface 22 (left end surface or right end surface) in the left-right direction of the body 2. The assembly frame 5 joins the body 2 and the cover 3 by being attached to the container body 4 so as to hold the first protrusions 34 and the second protrusions 24 from both sides in the front-rear direction. In other words, the assembly frame 5 has the first protrusion 34 and the second protrusion 24 sandwiched between the first protrusion 34 and the first protrusion 34 with the body 2 and the cover 3 being combined in the front-rear direction. It prevents that the 2nd protrusion 24 leaves | separates relatively. Thereby, the opening between the body 2 and the cover 3 is prevented, and the body 2 and the cover 3 are combined.

  Here, when the wiring device 1 is attached to the construction surface 800 (see FIG. 1), for example, the fixing screw may be further tightened from the state where the rear surface of the cover 3 is in contact with the construction surface 800. In such a case, the rear surface of the first protrusion 34 is located slightly in front of the four corners of the cover 3 as viewed from the rear so that the first protrusion 34 provided on the cover 3 is not damaged. Yes. That is, in such a case, the four corners of the cover 3 come into contact with the construction surface 800 prior to the first protrusion 34, and the first protrusion 34 is damaged in order to connect the body 2 and the cover 3. Can be avoided.

(2.2) Coupling structure Next, the coupling structure 101 in the wiring device 1 will be described in more detail with reference to FIGS. 5A to 7B. Since a plurality (four in this case) of the coupling structures 101 have a common configuration, the following description will be focused on one coupling structure 101 unless otherwise specified, and the other coupling structures 101 have the same configuration. The explanation is omitted. Here, attention is paid to the coupling structure 101 located at the upper right (portion indicated by “A1” in FIG. 4) of the four corners when the wiring device 1 is viewed from the front. The arrows indicating “front-rear direction”, “left-right direction”, and “up-down direction” in FIGS. 5A to 7B are also described based on the upper right coupling structure 101 among the four corners. Therefore, for example, regarding the coupling structure 101 located at the upper left of the four corners when the wiring device 1 is viewed from the front, the left and right are reversed from the following description.

  As shown in FIGS. 5A to 5C, the assembly frame 5 in the coupling structure 101 includes a first side 51, a second side 52, and a connecting side 53. The first side portion 51 and the second side portion 52 are arranged at a certain interval in the front-rear direction so that the first side portion 51 is on the front side. As will be described in detail later, the first side 51 comes into contact with the first protrusion 34 from the side opposite to the second protrusion 24 in the front-rear direction (that is, the front side). The second side 52 contacts the second protrusion 24 from the side opposite to the first protrusion 34 in the front-rear direction (that is, the rear side). The connecting side 53 connects the first side 51 and the second side 52.

  In the present embodiment, the connecting side portion 53 has three crosspieces 531 arranged in the vertical direction. That is, the first side 51 and the second side 52 are connected by the three crosspieces 531. Here, among the three crosspieces 531, the crosspieces 531 located on both sides in the vertical direction connect the top ends of the first side 51 and the second side 52 in the vertical direction, and the first side 51 and the lower end part of the 2nd edge part 52 of the up-down direction are connected. Of the three crosspieces 531, the central crosspiece 531 connects the central portions in the vertical direction of the first side 51 and the second side 52. In other words, the first side portion 51, the second side portion 52, and the crosspieces 531 on both sides of the three crosspieces 531 are arranged to form a rectangular frame shape when viewed from one side in the left-right direction. Yes. Further, the area surrounded by the first side 51, the second side 52, and the crosspieces 531 on both sides of the three crosspieces 531 is separated in the vertical direction by the central crosspiece 531. A pair of assembly holes 54 is formed.

  By the way, in the wiring device 1 which concerns on this embodiment, since the cover 3 is comprised more widely than the body 2 in the left-right direction as mentioned above, the one end surface 32 of the cover 3 and the one end surface of the body 2 are comprised. There is a difference in level between the two. Therefore, the assembly frame 5 attached to the left and right end faces of the body 2 and the cover 3 adopts the configuration described below in order to adapt to such a step.

  That is, the first side portion 51 and the second side portion 52 are arranged so as to be shifted from each other in the left-right direction. In short, the first side 51 on the cover 3 side is arranged on the outer side in the left-right direction compared to the second side 52 on the body 2 side so as to correspond to the cover 3 wider than the body 2. Yes. Here, “outside in the left-right direction” means the side opposite to the center of the body 4 in the left-right direction, and is “right” in the assembly frame 5 attached to the right end surface of the body 4. In the assembly frame 5 attached to the left end surface of No. 4, it becomes the “left side”. Specifically, a step portion 534 is formed in a part of the connecting side portion 53 in the front-rear direction. The connecting side portion 53 (the crosspiece portion 531) is positioned so that the first side portion 51 side is located on the outer side in the left-right direction than the second side portion 52 side (right side in the example of FIG. 5C) with the stepped portion 534 as a boundary.

  In the present embodiment, the first mounting portion 57 has a pair of first mounting pieces 570 that are separated in the vertical direction. The second attachment portion 58 has a pair of second attachment pieces 580 separated in the vertical direction. The pair of first attachment pieces 570 are configured to protrude from both end surfaces in the vertical direction of the assembly frame 5 to both sides in the vertical direction. Here, the pair of first attachment pieces 570 is provided in a portion of the crosspiece 531 that is closer to the first side 51 than the step 534. The pair of second mounting pieces 580 are configured to protrude from the outer surface in the left-right direction of the assembly frame 5 (the right end surface in the example of FIG. 5C). Here, the pair of second attachment pieces 580 are provided at positions straddling the first side 51, the crosspiece 531, and the side wall 56. Accordingly, the first mounting portion 57 and the second mounting portion 58 are arranged at different positions in the vertical direction so that the pair of second mounting pieces 580 are positioned inside the pair of first mounting pieces 570 in the vertical direction. Has been.

  Further, the second attachment portion 58 has a front surface 582 facing forward. The front surface 582 of the second mounting portion 58 (a pair of second mounting pieces 580) is an edge on the opposite side to the body 4 from the edge on the side of the body 4 in the left-right direction (the left edge in the example of FIG. 5C). It is an inclined surface that is inclined so that (the right end edge in the example of FIG. 5C) is located rearward. That is, the front surface 582 of the second attachment portion 58 is an inclined surface that is inclined outward in the left-right direction. Here, the front surface 571 of the first mounting portion 57 is located behind the front surface 582 of the second mounting portion 58. When the front surface 582 of the second attachment portion 58 is an inclined surface as in the present embodiment, the first attachment portion 57 is more than the end edge (the right end edge in the example of FIG. 5C) that is the rear end of the front surface 582. The front surface 571 is located rearward. Details of the appliance-side attachment portion 102 will be described in the section “(2.4) Attachment structure of wiring appliance to attachment frame”.

  Further, the assembly frame 5 has a plurality of press-fitting ribs 59 protruding from the inner peripheral surfaces of the pair of assembly holes 54 toward the inside of the assembly hole 54. In this embodiment, the 1st edge part 51, the 2nd edge part 52, the connection edge part 53, the leg piece 55, the side wall 56, and the instrument side attachment part 102 (the 1st attachment part 57 and the 2nd attachment part 58). The plurality of press-fitting ribs 59 are integrally formed by resin molding.

  As shown in FIG. 6, the assembly frame 5 configured as described above is attached to the container body 4 in a state where the body 2 and the cover 3 are combined in the front-rear direction. In a state in which the assembly frame 5 is attached to the container body 4, the first side portion 51 contacts the first protrusion 34 from the side opposite to the second protrusion 24 in the front-rear direction (that is, the front side). Similarly, the second side 52 contacts the second protrusion 24 from the side opposite to the first protrusion 34 in the front-rear direction (that is, the rear side). Therefore, the assembly frame 5 connects the body 2 and the cover 3 by sandwiching the first protrusion 34 and the second protrusion 24 between the first side 51 and the second side 52 in the front-rear direction. To do.

  In other words, as shown in FIGS. 7A and 7B, the first protrusion 34 and the second protrusion 24 are fitted into the pair of assembly holes 54 in the assembly frame 5, so that the space between the body 2 and the cover 3 is reduced. Is prevented from opening, and as a result, the joined state of the body 2 and the cover 3 is maintained. At this time, the side wall 56 is abutted with the front end surface of the first protrusion 34 in the left-right direction. That is, the front end surface of the first protrusion 34 fitted in the pair of assembly holes 54 is abutted against the side wall 56 that covers a part of the pair of assembly holes 54 from the outside in the left-right direction.

  Further, in a state where the assembly frame 5 is attached to the container body 4, the first protrusion 34 and the second protrusion 24 crush the plurality of press-fitting ribs 59 formed on the inner peripheral surface of the assembly hole 54. Then, it is press-fitted into the assembly hole 54. Thereby, the dimensional dispersion | variation between a pair of assembly hole 54, the 1st protrusion part 34, and the 2nd protrusion part 24 can be absorbed by the deformation | transformation (plastic deformation) of the press-fit rib 59, and Shaking of the assembly frame 5 is suppressed.

  Here, in the present embodiment, the plurality of press-fitting ribs 59 are provided so as to avoid a portion of the connecting side portion 53 closer to the first side portion 51 than the stepped portion 534. In other words, the press-fitting rib 59 of the connecting side portion 53 is omitted for the portion of the pair of assembly holes 54 where the opening in the left-right direction is closed by the side wall 56. That is, in the portion of the connecting side portion 53 that is closer to the first side portion 51 than the step portion 534, the interval between the adjacent crosspieces 531 is restricted by the side wall 56. ) Between the adjacent crosspieces 531 does not substantially change. Therefore, if the press-fitting rib 59 is provided in the portion of the connecting side portion 53 closer to the first side portion 51 than the stepped portion 534, the assembly frame 5 is deformed so that the opening side (the inner side in the left-right direction) opens. However, attachment of the assembly frame 5 to the container 4 may be insufficient. On the other hand, in the configuration of this embodiment, when the first protrusion 34 and the second protrusion 24 are press-fitted into the pair of assembly holes 54, the outer side of the pair of assembly holes 54 on the outer side in the left-right direction. In the portion where the opening is blocked by the side wall 56, it is possible to suppress the opening side (the inner side in the left-right direction) from opening.

  Incidentally, as shown in FIG. 7A, the cover 3 further has an assembly groove 321 along the front-rear direction on one end surface 32 in the left-right direction. The connecting side 53 of the assembly frame 5 is configured to fit into the assembly groove 321. In the present embodiment, since the connecting side portion 53 includes three crosspieces 531, three assembly grooves 321 are formed in the cover 3 so as to correspond thereto. In the present embodiment, the three assembly grooves 321 are formed from the cover 3 to the body 2.

  Further, the first protrusion 34 has a pair of first protrusions 341 that are separated in the vertical direction by a central crosspiece 531 among the three crosspieces 531. Similarly, the second protrusion 24 has a pair of second protrusions 241 that are separated in the vertical direction by a central crosspiece 531 among the three crosspieces 531. In other words, the first protrusion 34 is separated into a pair of first protrusions 341 by the central assembly groove 321 among the three assembly grooves 321. Similarly, the second protrusion 24 is separated into a pair of second protrusions 241 by a central assembly groove 321 among the three assembly grooves 321. As a result, in a state where the assembly frame 5 is attached to the container body 4, one first projection 341 and one second projection 241 are fitted into one assembly hole 54, and the other assembly hole 54 is fitted with the other first. One projection 341 and the other second projection 241 are fitted.

  A pair of hook holes 41 into which the pair of leg pieces 55 are inserted are formed at positions corresponding to the pair of leg pieces 55 in the container body 4. In the present embodiment, each of the pair of hooking holes 41 is formed across the body 2 and the cover 3. The assembly frame 5 is attached to the body 4 so that the hooking claws 551 of the pair of leg pieces 55 are hooked on the edges of the pair of hooking holes 41. That is, since the first protrusion 34 and the second protrusion 24 are press-fitted into the assembly hole 54, the assembly frame 5 is difficult to drop off from the body 4. 5 becomes more difficult to drop off.

(2.3) Attachment frame Next, the structure of the attachment frame 8 is demonstrated with reference to FIG. 8A-FIG. 12B.

Each of the pair of metal plates 720 includes a first part 721, a second part 722, and a third part 723. That is, the reinforcing member 72 is configured by a pair of physically separated metal plates 720 instead of a single metal plate integrated as a whole. Here, each of the pair of metal plates 720 is not formed in a flat plate shape, but is formed in a three-dimensional shape by the third portion 723 projecting forward.

  The reinforcing member 72 is fixed to the resin frame 71 at both the first part 721 and the second part 722. Specifically, each vertical frame 83 of the resin frame 71 is formed with a plurality of (here, two) caulking projections 712 protruding from the front surface 711. A plurality of (here, two) caulking holes 724 that penetrate the second portion 722 in the front-rear direction are formed in the second portion 722 of the reinforcing member 72. The second portion 722 of the reinforcing member 72 is caulked and fixed to the resin frame 71 by the plural caulking protrusions 712 in a state where the plural caulking protrusions 712 are inserted into the plural caulking holes 724. Similarly, in each horizontal frame 84 of the resin frame 71, a plurality (four in this case) of caulking protrusions 714 protruding from the front surface 711 are formed. A plurality (four in this case) of caulking holes 726 penetrating the first portion 721 in the front-rear direction are formed in the first portion 721 of the reinforcing member 72. The first portion 721 of the reinforcing member 72 is caulked and fixed to the resin frame 71 by the plural caulking projections 714 in a state where the plural caulking projections 714 are inserted into the plural caulking holes 726.

FIG. 15 is a bottom view of the wiring device 1 attached to the attachment frame 8 as viewed from below, and a shaded area (dot hatching) represents the cover 3. In FIG. 15, the construction surface 800 is indicated by an imaginary line (two-dot chain line).

  In the wiring device 1, as described above, the cover 3 is larger than the body 2 in the left-right direction, that is, the cover 3 is configured to be wider. Further, a portion of the cover 3 positioned behind the surface of the construction surface 800, that is, in the wall (inside the embedding box) is set to have the same horizontal dimension as the horizontal dimension of the body 2. Therefore, as shown in FIG. 15, the mounting frame 800 and the cover 3 do not protrude in the left-right direction behind the surface of the construction surface 800, and are in the wall (in the embedding box) of the wiring device 1. The size of the part that fits can be kept small.

  In the state where the wiring device 1 is attached to the attachment frame 8, as shown in FIG. 16, the first attachment portion 57 and the second attachment portion 58 in the appliance-side attachment portion 102 have the first restriction in the frame-side attachment portion 6. The wiring device 1 is fixed by contacting the portion 61 and the second restricting portion 62. In other words, the instrument-side mounting portion 102 has a mounting frame in which the front surface 571 of the first mounting portion 57 contacts the mounting frame 8 from the rear and the rear surface 581 of the second mounting portion 58 contacts the mounting frame 8 from the front. 8 to restrict the movement of the container 4 in the front-rear direction. In other words, the frame-side attachment portion 6 is configured such that the rear surface 611 of the first restricting portion 61 contacts the wiring device 1 from the front, and the front surface 621 of the second restricting portion 62 contacts the wiring device 1 from the rear. The movement of the wiring device 1 relative to the main body 80 in the front-rear direction is restricted.

  Specifically, as shown in FIG. 17A, the instrument side mounting portion 102 is configured so that the front surface 571 (see FIG. 5A) of the first mounting portion 57 (the pair of first mounting pieces 570) is the first in the frame side mounting portion 6. The first regulating portion 61 (a pair of first regulating pieces 610) is brought into contact with the rear surface 611 (see FIG. 12B). Accordingly, the forward movement of the wiring device 1 relative to the frame body 80 is restricted. At this time, the dowel 612 formed on the rear surface 611 of the first restricting portion 61 is crushed by the front surface 571 of the first mounting portion 57 and plastically deformed. For this reason, even if there is a slight dimensional error between the fixture-side mounting portion 102 and the frame-side mounting portion 6, the influence of the dimensional error can be absorbed by the plastic deformation of the dowel 612. Shaking is suppressed. In this state, the front surface 571 of the first mounting portion 57 contacts only the rear surface 611 of the first restricting portion 61 and does not contact the rear surface of the reinforcing rib 613.

  Similarly, as shown in FIG. 17B, the instrument side mounting portion 102 has a rear surface 581 (see FIG. 5A) of the second mounting portion 58 (a pair of second mounting pieces 580) and a second restriction on the frame side mounting portion 6. It is made to contact the front surface 621 (refer FIG. 12B) of the part 62 (a pair of 2nd control piece 620). As a result, the wiring device 1 is restricted from moving backward relative to the frame body 80. Accordingly, the wiring device 1 is restricted from moving in the front-rear direction with respect to the frame body 80.

  The vertical dimension of the wiring device 1 is substantially the same as the vertical dimension of the opening window 81, and the horizontal dimension of the wiring device 1 excluding the second mounting portion 58 is the horizontal direction of the opening window 81. The dimensions are substantially the same. Therefore, the movement of the container 4 with respect to the mounting frame 8 is restricted in both the vertical direction and the horizontal direction. Furthermore, the movement of the container 4 with respect to the mounting frame 8 in the vertical direction may be restricted by sandwiching the vertical walls of the release recess 835 between the pair of second mounting pieces 580.

  By the way, in the wiring device 1 attached to the construction surface 800 (see FIG. 1) using the mounting frame 8 as described above, wiring is performed at the time of construction of the wiring device 1 (at the time of installation) or when the wiring device 1 is used. A relatively large force may act on the instrument 1 in the front-rear direction. For example, when the mounting frame 8 with the wiring device 1 attached is attached to the construction surface 800, the wiring device 1 is pushed forward with respect to the wiring device 1 from the wiring connected to the wiring device 1. Force acts. In addition, when the wiring device 1 is used, when the plug is removed by holding the power cord, or when a person's foot is caught on the power cord, the wiring device 1 is against the wiring device 1. The force of pulling forward acts. Further, when the wiring device 1 is used, a force that pushes the wiring device 1 backward acts on the wiring device 1 when the plug is inserted. Even when such a force is applied, in the wiring device 1 according to the present embodiment, the movement of the wiring device 1 in the front-rear direction with respect to the frame body 80 is restricted as described above. Shaking is suppressed.

(3) Modifications The wiring device 1, the mounting frame 8, or the assembly frame 5 according to the first embodiment is merely an example of the present invention, and the present invention is not limited to the first embodiment. Other than the above, various modifications can be made according to the design and the like as long as they do not depart from the technical idea of the present invention. Below, the modification of Embodiment 1 is enumerated.

(3.1) First Modification A wiring device 1A according to a first modification of Embodiment 1 has a unit body 4A as shown in FIG. Is different. In other words, the wiring device 1 </ b> A has a device main body 40 </ b> A having a size that allows attachment of up to three pieces to the attachment frame 8. In this wiring device 1 </ b> A, the body 2 </ b> A and the cover 3 </ b> A are coupled by a pair of assembly frames 5. Only one set of two insertion holes 311A is formed on the front surface 31A of the wiring device 1A. That is, the wiring device 1A is a single-port type outlet. For example, the wiring device 1A is attached to the center of the opening window 81 in the vertical direction.

(3.2) Second Modification The mounting frame 8A according to the second modification of the first embodiment is for two according to the first embodiment, as shown in FIG. This is different from the frame 8. In other words, the mounting frame 8A can mount an arbitrary number of unit bodies 4A in the range of 1 to 2 units. The attachment frame 8A has two pairs of frame side attachment portions 6A arranged in the vertical direction. Similarly to the frame-side attachment portion 6 of the attachment frame 8 according to the first embodiment, the frame-side attachment portion 6A includes a first restriction portion 61 (a pair of first restriction pieces 610) and a second restriction portion 62 (a pair of first portions). 2 restriction pieces 620).

(3.3) Third Modification As shown in FIG. 20, the assembly frame 5A according to the third modification of Embodiment 1 is implemented in that the first attachment portion 57 (see FIG. 5A) is omitted. This is different from the assembly frame 5 according to the first embodiment. That is, in the assembly frame 5A, there is no pair of first mounting pieces 570 (see FIG. 5A) that protrude from both end surfaces of the assembly frame 5 in the vertical direction, and the vertical dimension of the assembly frame 5 is kept small. be able to. The wiring device 1 using the assembly frame 5A is mounted in such a manner that the front surface of the first side 51 is brought into contact with the mounting frame 8 from the rear instead of the front surface 571 of the first mounting portion 57 (see FIG. 5A). It is attached to the frame 8. That is, when attaching the wiring device 1 using the assembly frame 5A, an attachment frame having a restricting portion at a position in contact with the front surface of the first side portion 51 is used instead of the first restricting portion 61 (see FIG. 16). .

(3.4) Fourth Modification As shown in FIGS. 21A and 21B, the wiring device 1B according to the fourth modification of the first embodiment is such that the assembly frame 5B is in the front-rear direction with respect to the first protrusion 34B. The wiring device 1 according to the first embodiment is different from the wiring device 1 according to the first embodiment in that the auxiliary rib 532 further contacts from the second protrusion 24 side (rear side). That is, the assembly frame 5B has the auxiliary ribs 532 at positions facing the first side 51 with a certain distance in the front-rear direction. The auxiliary rib 532 is disposed between the first side 51 and the second side 52 in the front-rear direction. In the example of FIG. 21A, a pair of auxiliary ribs 532 are provided on the inner peripheral surface of each of the pair of assembly holes 54, and a total of four auxiliary ribs 532 are provided for the assembly frame 5. A pair of auxiliary ribs 532 provided in each assembly hole 54 protrude from the stepped portion 534 (see FIG. 5B) of the connecting side portion 53 toward the first side portion 51 in a direction approaching each other in the vertical direction. .

  In the wiring device 1B according to the fourth modification, the first protrusion 34B has a pair of protruding pieces 342 protruding from the rear surfaces of the pair of first protrusions 341. Each protruding piece 342 is provided at the center in the vertical direction on the rear surface of each first protrusion 341. In other words, the rear surfaces of the pair of first protrusions 341 are not flat surfaces, but are formed in a shape in which both ends in the vertical direction are recessed.

  In the state where the assembly frame 5B is attached to the vessel body 4, as shown in FIG. Contact. In other words, the assembly frame 5 </ b> B is attached to the container body 4 with the pair of first protrusions 341 held between the pair of auxiliary ribs 532 and the first side portion 51. At this time, in the first protrusion 34B, the protruding piece 342 is sandwiched between the pair of auxiliary ribs 532 in the vertical direction.

  According to the configuration of the wiring device 1B according to the fourth modified example, the first protrusion 34B is supported by the auxiliary rib 532 from the second protrusion 24 side (rear side) in the front-rear direction. The auxiliary rib 532 can receive a force applied from the opposite side (front) of the second protrusion 24 in the front-rear direction. Therefore, for example, even when a large force in the direction of pushing (or pulling) the wiring device 1 forward is applied during construction (attachment) of the wiring device 1 or when the wiring device 1 is used, the auxiliary rib 532 The first protrusion 34B can be protected and damage to the first protrusion 34B can be suppressed.

  However, in this case, in a state in which the wiring device 1B is attached to the construction surface 800 (see FIG. 1), substantially the entire protruding piece 342 fits in the wall (in the embedded box). Therefore, the dimension in the left-right direction of the wiring device 1B that fits in the wall (in the embedded box) is larger than that of the wiring device 1 according to the first embodiment.

(3.5) Other Modifications Modifications other than the first modification to the fourth modification of the first embodiment are listed below.

  The wiring device 1 is not limited to indoor use but may be an outdoor device used outside the building. In addition, the wiring device 1 is not limited to having a ground electrode, but may have no ground electrode, or may be an outlet for AC 100V or DC. Furthermore, the wiring device 1 is not limited to an outlet that is compatible with A type and C type plugs. For example, only the A type plug, or an outlet that can connect a B type, BF type, C type, or O type plug. It may be. The wiring device 1 is not limited to a two-port type outlet, and may be, for example, a one-port type or a three-port type outlet. Furthermore, the wiring device 1 is not limited to an outlet, and may be a switch, a human sensor, a timer, or the like. Furthermore, the wiring device 1 may be a combination of two or more functions of an outlet, a switch, a human sensor, a timer, and the like, such as an outlet with a human sensor. Moreover, the terminal part of the wiring instrument 1 may not be a quick connection terminal, for example, may be a screw-type terminal.

  The wiring device 1 is not limited to a configuration in which the rear portion is embedded in the wall (embedded installation type), but may be configured to be installed on the wall in an exposed state (exposed installation type). Good. In addition, the attachment frame 8 is not limited to a configuration that is fixed to the embedding box, and may be a configuration that is attached to the construction surface 800 using, for example, a scissor fitting.

  Further, in the assembly frame 5, the first side 51 and the second side 52 only need to be shifted from each other in the left-right direction. For example, the position of the first side 51 and the second side in the left-right direction. A part of the position 52 may overlap. In this case, a part of the second side portion 52 is located in the projection plane along the front-rear direction of the first side portion 51.

  Further, the hooking claw 551 provided at the tip of the leg piece 55 may be hooked on at least one of the body 2 and the cover 3, and may be configured to hook only on the body 2 or only the cover 3, for example. .

  Further, the assembly frame 5 is not limited to the configuration having the three crosspieces 531, and may have one or two or four or more crosspieces 531. For example, when the assembly frame 5 has two crosspieces 531, the assembly frame 5 has a rectangular frame shape. In this case, the first protrusion 34 has a shape in which a pair of first protrusions 341 are integrated, and the second protrusion 24 has a shape in which a pair of second protrusions 241 are integrated.

  Further, the assembly frame 5 is not limited to the mounting frame 8 and may be integrated with the mounting frame 8. In this case, the body 2 and the cover 3 are coupled to each other by the assembly frame 5 integrated with the mounting frame 8.

  Further, the dowel 612 that is plastically deformed when the wiring device 1 is attached to the attachment frame 8 only needs to protrude from at least one of the rear surface 611 of the first restricting portion 61 and the front face 621 of the second restricting portion 62. You may protrude from the front surface 621 of the control part 62. FIG. In this case, the dowel 612 is crushed by the rear surface 581 of the second attachment portion 58 and plastically deformed.

  Further, the front surface 571 of the first mounting portion 57 may be at the same position as the rear surface 581 of the second mounting portion 58 in the first direction. In this configuration, as compared with the configuration of the wiring device 1 according to the first embodiment, the second mounting portion 58 has the rear surface 581 of the second mounting portion 58 flush with the front surface 571 of the first mounting portion 57 (same plane). It becomes the structure which went down back to the position. That is, in the wiring device 1 according to the first embodiment, the front surface 571 of the first mounting portion 57 is positioned slightly forward (for example, 0.5 mm) from the rear surface 581 of the second mounting portion 58, but the front surface 571 and the rear surface It may be set flush with 581. Therefore, according to this configuration, the forward protrusion amount of the second mounting portion 58 from the front surface 571 of the first mounting portion 57 is suppressed to be relatively small, and the pair of instrument side mounting portions 102 in the first direction is thinned. Can be achieved. Similarly, in the attachment frame 8, the rear surface 611 of the first restricting portion 61 may be at the same position as the front surface 621 of the second restricting portion 62 in the first direction. However, the front surface 571 of the first mounting portion 57 and the rear surface 581 of the second mounting portion 58 do not have to be at the same position in the first direction. It is possible to ensure both strength and thickness reduction of the side attachment portion 102 and the frame side attachment portion 6). For example, the front surface 571 of the first mounting portion 57 may be in a position shifted in the first direction within a range of 0 mm or more and less than 3 mm with respect to the rear surface 581 of the second mounting portion 58.

  The method of fixing the reinforcing member 72 to the resin frame 71 is not limited to the caulking fixing as described above. For example, the reinforcing member 72 is fixed to the resin frame 71 by a method such as adhesion, pressure bonding, or screwing. May be. The resin frame 71 may be insert-molded so as to be integrated with the reinforcing member 72.

(4) Summary As described above, the mounting frame 8 according to the first aspect includes the resin frame 71 made of synthetic resin and the reinforcing member 72 made of metal and fixed to the resin frame 71. . The resin frame 71 has an opening window 81 penetrating in the first direction (front-rear direction), and the wiring device 1 is attached by inserting the wiring device 1 into the opening window 81. The resin frame 71 includes a pair of vertical frames 83 opposed to each other through the opening window 81 in a second direction (left-right direction) orthogonal to the first direction, and a third direction orthogonal to both the first direction and the second direction ( A pair of horizontal frames 84 facing each other through the opening window 81 in the vertical direction). The pair of vertical frames 83 connects between both ends of the one horizontal frame 84 in the second direction of the pair of horizontal frames 84 and both ends of the other horizontal frame 84 in the second direction. The reinforcing member 72 is attached to the front surface 711 side of the resin frame 71 so as to cover a part of the front surface 711 facing forward, which is one of the first directions in the resin frame 71. The reinforcing member 72 includes a first portion 721 positioned in front of the pair of horizontal frames 84, a second portion 722 positioned in front of the root portion 836 connected to at least the pair of horizontal frames 84 of the pair of vertical frames 83, and Have

  According to this configuration, the second portion 722 of the metal reinforcing member 72 is positioned in front of the base portion 836 connected to at least the pair of horizontal frames 84 of the pair of vertical frames 83 of the synthetic resin resin frame 71. doing. Therefore, even when a force that causes the pair of vertical frames 83 to bend forward acts on the resin frame 71 from the wiring device 1, the second portion 722 of the reinforcing member 72 restricts the deformation of the pair of vertical frames 83 toward the front. Is done. Therefore, it is possible to prevent a part of the mounting frame 8 (the pair of vertical frames 83) from being lifted from the construction surface 800 such as a wall surface. As a result, the mounting frame 8 can suppress the lifting from the construction surface 800. There is an advantage that. In particular, for example, when the mounting frame 8 with the wiring device 1 attached is attached to the construction surface 800, the wiring device 1 is pushed forward from the wiring connected to the wiring device 1 to the wiring device 1. Directional force acts. In addition, when the wiring device 1 is used, when the plug is removed by holding the power cord, or when a person's foot is caught on the power cord, the wiring device 1 is against the wiring device 1. The force of pulling forward acts. Thus, even if a large force is applied to push (or pull) the wiring device 1 forward, the forward deformation of the pair of vertical frames 83 is restricted. Can be prevented from rising.

  In the mounting frame 8 according to the second aspect, in the first aspect, it is preferable that the first part 721 and the second part 722 are integrally formed. According to this configuration, compared to the case where the first part 721 and the second part 722 are separate, the forward deformation of the pair of vertical frames 83 is more restricted by the second part 722, and the attachment frame 8 The lift from the construction surface 800 can be more reliably suppressed. However, this configuration is not an essential configuration for the attachment frame 8, and the first portion 721 and the second portion 722 may be separate.

  In the mounting frame 8 according to the third aspect, in the second aspect, the reinforcing member 72 has a pair of metal plates 720, and each of the pair of metal plates 720 includes a first part 721 and a second part 722. It is preferable to have. According to this configuration, the reinforcing member 72 can dispose the metal plate 720 only in a portion of the resin frame 71 that needs reinforcement, so that the necessary metal plate 720 can be reduced. However, this configuration is not an essential configuration for the mounting frame 8, and the reinforcing member 72 may be configured by a single metal plate.

  In the mounting frame 8 according to the fourth aspect, in any one of the first to third aspects, the reinforcing member 72 may be fixed to the resin frame 71 at both the first part 721 and the second part 722. preferable. According to this configuration, the reinforcing member 72 not only restricts the forward deformation of the pair of vertical frames 83, but can also suppress the deformation of the entire resin frame 71, and lift the mounting frame 8 from the construction surface 800. Can be suppressed more reliably. However, this configuration is not essential for the mounting frame 8. For example, the reinforcing member 72 may be fixed to the resin frame 71 only at the first portion 721.

  In the mounting frame 8 according to the fifth aspect, in any one of the first to fourth aspects, the pair of vertical frames 83 is provided on each of the pair of inner side surfaces 831 facing the opening window 81 side in the pair of vertical frames 83. It is preferable to have the formed regulating recess 832. In this case, the resin frame 71 is attached to the wiring device 1 in a state in which the mounting claws (second mounting portion 58) protruding from both end surfaces in the second direction of the wiring device 1 are inserted into the restriction recesses 832. It is preferable that it is comprised. According to this configuration, the wiring device 1 can be attached to and detached from the frame body 80 by bending at least one of the pair of vertical frames 83 in the second direction. Flexibility is imparted. In this case, since at least one of the pair of vertical frames 83 is easily deformed forward, it is particularly useful that the forward deformation of the pair of vertical frames 83 is restricted by the reinforcing member 72. However, this configuration is not an essential configuration for the mounting frame 8, and the restriction recess 832 can be omitted as appropriate.

  In the mounting frame 8 according to the sixth aspect, in any one of the first to fifth aspects, the resin frame 71 protrudes from the front surface 711 of the resin frame 71 and is inserted into the caulking hole 724 formed in the reinforcing member 72. It is preferable to further have a caulking projection 712. In this case, it is preferable that the reinforcing member 72 further has a protective protrusion 725 that protrudes from a surface of the second portion 722 facing the front surface 711 of the resin frame 71 and is inserted into a protective recess 713 formed in the resin frame 71. . In this case, the reinforcing member 72 is caulked and fixed to the resin frame 71 by caulking protrusions 712, and the protective protrusions 725 are formed in the third direction between the center of the pair of vertical frames 83 in the third direction and the caulking holes 724. It is preferably located between. According to this configuration, when the vertical frame 83 is elastically deformed in the second direction, a shear stress acts on the protective projection 725, and the shear stress acting on the caulking projection 712 can be reduced. However, this configuration is not essential for the mounting frame 8, and the protective protrusion 725 can be omitted as appropriate.

  In the attachment frame 8 according to the seventh aspect, in any one of the first to sixth aspects, each of the root portions 836 of the pair of vertical frames 83 is raised forward at the end portion on the opening window 81 side in the second direction. It is preferable to have a raised portion 837. In this case, the reinforcing member 72 further includes a third portion 723 that connects the first portion 721 and the second portion 722, and the third portion 723 has a shape that protrudes forward along the protruding portion 837. Is preferred. According to this configuration, the raised portion 837 improves the rigidity of the root portion 836 of the pair of vertical frames 83, and the attachment strength of the wiring device 1 to the frame body 80 is improved. Moreover, since the first part 721 and the second part 722 are connected by the third part 723 that is raised forward along the raised portion 837, the first part 721 and the second part 722 are separated from the construction surface 800. The amount of protrusion can be kept small. However, this configuration is not an essential configuration for the mounting frame 8, and the raised portion 837 can be omitted as appropriate.

  In the mounting frame 8 according to the eighth aspect, in any one of the first to seventh aspects, at least one of the pair of vertical frames 83 is configured to be elastically deformable in the second direction over the entire width in the second direction. Preferably it is. According to this configuration, since at least one of the pair of vertical frames 83 is elastically deformed in the second direction as a whole, the width dimension (dimension in the second direction) of at least one of the pair of vertical frames 83 is compared. Can be made small. Therefore, although the outer peripheral dimension of the frame main body 80 is the same, a large dimension in the second direction of the opening window 81 can be secured. However, this configuration is not an essential configuration for the mounting frame 8, and for example, only a part of the pair of vertical frames 83 in the second direction (ends on the opening window 81 side) may be elastically deformed.

(Embodiment 2)
The wiring device 1C according to the second embodiment is different from the wiring device 1 according to the first embodiment in that the wiring device 1C is a switch including a switch handle 400 as shown in FIG.

Here, the container body 4 </ b> C is formed to have a dimension (unit dimension) that allows up to three attachments to the attachment frame 8 (see FIG. 2). Since the mounting frame 8 to which the wiring device 1C is mounted has the same configuration as that of the first embodiment, detailed description thereof is omitted here.

  Here, as in the first embodiment, the cover 3C is configured to be larger than the body 2C in the left-right direction (second direction).

The two pairs of coupling structures 101C are provided at the four corners of the body 4C as viewed from the front so as to be aligned in the left-right direction on each of the vertical end faces (upper surface or lower end surface) of the body 4C. Therefore, the body 2C and the cover 3C are coupled at the four corners of the container 4C as viewed from the front.

  Here, each of the plurality of coupling structures 101C includes a coupling frame 35C that projects rearward from the rear surface of the cover 3C, and a coupling claw 25C that projects from each end surface (upper end surface or lower end surface) in the vertical direction of the body 2C.

  Each of the pair of appliance-side attachment portions 102C is realized by a configuration in which a part of the assembly frame 5 (see FIG. 7A) of the wiring appliance 1 according to Embodiment 1 is integrated with the cover 3C. That is, a configuration in which the second side 52 (see FIG. 7A) and the connecting side 53 (see FIG. 7A) are omitted from the assembly frame 5 is formed integrally with the cover 3C on both sides in the left-right direction of the cover 3C. Thus, a pair of appliance-side attachment portions 102C is realized. Therefore, each of the pair of appliance-side attachment portions 102C has a first attachment portion 57C and a second attachment portion 58C as shown in FIG. The first attachment portion 57C and the second attachment portion 58C correspond to the first attachment portion 57 (see FIG. 16) and the second attachment portion 58 (see FIG. 16) in the assembly frame 5 of the first embodiment, respectively.

  That is, in the first embodiment, the coupling structure 101 (see FIG. 4) and the instrument side mounting portion 102 (see FIG. 16) are both provided on both sides in the left-right direction of the vessel body 4, and the coupling structure 101 The assembly frame 5 is also used by the instrument side mounting portion 102. On the other hand, in the second embodiment, at least a pair of coupling structures 101C are provided on both sides of the body 2C and the cover 3C in the up-down direction, and at least a pair of instrument side mounting portions 102C are provided on both sides of the cover 3C in the left-right direction. ing.

  As described above, the coupling structure 101C has at least one pair on both sides of the body 2C and the cover 3C in the third direction (vertical direction) orthogonal to both the first direction (front-rear direction) and the second direction (horizontal direction). It is preferable to be provided. That is, the cover 3C is wide in the second direction, whereas the coupling structure 101C is provided on both sides in the third direction instead of the second direction. According to this configuration, the space (the volume of the container 4C) that is widened in the second direction of the cover 3C can be used in addition to the coupling structure 101C for coupling the body 2C and the cover 3C.

  In addition, as in the second embodiment, the wiring device 1C preferably further includes a pair of device-side attachment portions 102C provided on both sides of the cover 3C in the second direction. In this case, the body 2C and the cover 3C are configured to be attached to the attachment frame 8 having the opening window 81 penetrating in the first direction by the pair of instrument side attachment portions 102C in a state of being inserted into the opening window 81. It is preferable. That is, the cover 3C is wide in the second direction, whereas the pair of instrument side mounting portions 102C are provided on both sides in the second direction. According to this configuration, the space obtained by widening the cover 3C in the second direction can be used for the instrument-side attachment portion 102C for attaching the body 2C and the cover 3C to the attachment frame 8. However, this configuration is not an essential configuration for the wiring device 1C, and the pair of device-side attachment portions 102C may be provided on both sides of the cover 3C in the third direction.

  The configuration of the present embodiment is merely an example. For example, the wiring device 1C may be a piano handle type switch instead of a rocker type (seesaw type) switch. Various configurations (including modifications) described in the second embodiment can be appropriately combined with the configurations (including modifications) described in the first embodiment.
