(Embodiment 1)
(1) Outline First, an outline 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 this embodiment is an outlet to which a plug of an electric device is connected to supply electric power to the electric device. Here, as the wiring device 1, a two-port type outlet for AC 220V with a grounding electrode and capable of simultaneously connecting two plugs is illustrated. In addition, in the present embodiment, as the wiring device 1, an indoor wiring device 1 attached to a wall of a building is illustrated. The building in which 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, by inserting a pin or a blade of a plug of an electric device into an insertion hole 311 formed in the front surface 31, the plug is electrically connected, and power is supplied from the wiring device 1 to the electric device. Will be possible. Here, the wiring device 1 is an embedded wiring device, and is attached to the construction surface 800 using the attachment frame 8 (see FIG. 2 ). The mounting frame 8 has an opening window 81. The mounting frame 8 is mounted on the construction surface 800 with the wiring device 1 mounted inside the opening window 81. Specifically, the attachment frame 8 is attached to the construction surface 800 by being fixed to the embedding box, for example. The embedding box here is a box-shaped member having an open front surface, and is installed in the wall so that the front surface is exposed to the front through a construction hole formed in the construction surface 800. Thereby, the wiring device 1 is attached to the construction surface 800 in a state where the front surface 31 is exposed to the front and at least a part (rear part) is embedded in the wall (in the embedding box).

Further, the 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 91. The decorative plate 9 is attached to the mounting frame 8 from the front surface of the mounting frame 8 to the peripheral surface of the mounting frame 8 so as to cover substantially the entire mounting 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 projections 92 on the edges of the plurality of 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 to the front as shown in FIG. 1.

In the present embodiment, the wiring fixture system 10 includes the wiring fixture 1 and the mounting frame 8. That is, the wiring device system 10 includes the wiring device 1 and the mounting frame 8 as constituent elements. 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 that constitutes the wiring device system 10 together with the mounting frame 8 is not limited to an outlet and may be, for example, a switch or the like.

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 body 4 in a state of being combined with each other. The body 4 houses internal components such as a blade receiving member and a terminal plate. The body 2 and the cover 3 are connected to each other by a plurality of (four in this case) 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 connecting the body 2 and the cover 3 together.

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 (horizontal direction) orthogonal to the first direction (front-back direction) in which the body 2 and the cover 3 are combined. ing. In short, the cover 3 is wider than the body 2 in the second direction. In other words, both end surfaces 32 (see FIG. 4) of the cover 3 orthogonal to the second direction are located outside the end surfaces 22 (see FIG. 4) of the body 2 orthogonal to the second direction. Here, the two end faces 32 of the cover 3 in the second direction are located outside the two end faces 22 of the body 2 in the second direction, so that the both end faces 32 of the cover 3 correspond to the two end faces 22 of the body 2 in the second direction. It means that there is no space (that is, inside), but outside both end faces 22. Thereby, the dimension of the wiring device 1 in the second direction when 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 (in the embedding box), that is, the area of the rear surface of the wiring device 1 can be suppressed smaller than that of 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 exposed in the front is increased, but the size of the portion that fits inside the wall (in the embedding box) is It can be kept small. The portion of the wiring device 1 exposed to the front, that is, the front surface 31, is a portion for the user to perform an operation (plugging/unplugging in the case of an outlet) when using the wiring device 1, so increase the size of this portion. Thus, the operability and design 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 and the mounting frame 8 and the decorative plate 9 located around the front surface 31. It also leads to the expansion of the insulation distance between them. 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 portion of the wiring device 1 that fits inside the wall (in the embedded box), there is room in the space around the wiring device 1 in the wall, and a space for storing wiring and the like is provided. It becomes easy to secure.

As described above, in the wiring device 1 according to the present embodiment, at least the body 2 and the cover 3 having different dimensions in the second direction are coupled to each other by the plurality of assembly frames 5. The plurality of (four in this case) assembly frames 5 are attached to both sides of the body 4 in the second direction with the body 2 and the cover 3 coupled to each other. In other words, at least one pair of coupling structures for coupling the body 2 and the cover 3 is provided on both sides of the body 4 (the body 2 and the cover 3) in the second direction.

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

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

In the present embodiment, the direction orthogonal to the construction surface 800 when the wiring equipment 1 is attached to the wall surface of the building that is the construction surface 800 is the “front-back direction”, and the front surface 31 of the wiring equipment 1 is directed. The side is described as “front”. Further, a direction that is orthogonal to the front-rear direction and that is parallel to the horizontal plane will be referred to as a “left-right direction”, the right side of the wiring device 1 when viewed from the front will be referred to as “right”, and the left side will be referred to as “left”. .. Further, a direction that is orthogonal to both the front-rear direction and the left-right direction, that is, a direction that is perpendicular (orthogonal) to the horizontal plane is referred to as the "up-down direction", and the lower side (vertical direction) when viewed from the front of the wiring device 1 is the "lower side" ". When the respective directions are defined in this way, the "front-back 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-back direction", "horizontal direction", and "up-down direction" in the drawings are shown for the sake of description only and have no substance.

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-back direction) is a direction perpendicular to the horizontal plane, and the second direction (left-right direction) and the third direction (up-down direction). Is parallel to the horizontal plane. Even when the wiring device 1 is mounted on a wall surface, the wiring device 1 is mounted on the wall surface in a direction in which the “vertical direction” is a direction parallel to the horizontal plane (that is, sideways), so that the “horizontal direction” is horizontal Vertical direction.

(2.1) Wiring Device First, the configuration of the wiring device 1 will be described with reference to FIGS. 2 to 4.

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 connecting the body 2 and the cover 3 together. In this embodiment, since the body 2 and the cover 3 are joined at four places, the wiring device 1 includes four assembly frames 5. Since a plurality of (four in this case) assembly frames 5 have a common structure, one assembly frame 5 will be described below unless otherwise specified, and the other assembly frames 5 have the same structure. 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 a surface facing the body 2, that is, a rear surface. Like the opening surface 21 of the body 2, the opening surface 33 of the cover 3 is formed in a vertically long rectangular shape. However, in the present 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 smaller than the opening surface 21 of the body 2 in the second direction. 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 shown by an imaginary line (two-dot chain line). In the example of FIG. 3, the central portion 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 portion of the peripheral wall of the cover 3 that surrounds the opening surface 33 in the up-down direction is formed in a concave shape that is recessed forward.

The body 2 and the cover 3 are combined with each other to form the body 4. In the present embodiment, the 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 housed in a space formed between the body 2 and the cover 3, that is, an internal space of the body 4. In short, the wiring device 1 includes the body 2 including the body 2 and the cover 3 which are separable from each other, and the body 2 and the body 2 are assembled by using the assembly frame 5 so as to store the internal parts in the inner space of the body 4. The cover 3 is assembled by being joined. That is, the assembly frame 5 constitutes an assembly member 50 (see FIG. 2) used for assembling the wiring device 1. The device body 40 (see FIG. 2) is a part of the wiring device 1 and includes a body 2 and a cover 3 that are connected to each other by an assembly frame 5. The instrument body 40 includes internal components in addition to the body 4 (body 2 and cover 3). That is, the wiring device 1 is composed of the device body 40 and the assembly frame 5. However, illustration of the internal parts housed in the body 4 is omitted in all the drawings.

Here, the body 2, the cover 3, and the assembly frame 5 are all made of synthetic resin having electric insulation. The body 2 and the cover 3 that form the body 4 that houses the internal parts are made of 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, one of the body 2 and the cover 3 is provided with a claw, and the other is provided with a hole into which the claw fits. A coupling of 2 and cover 3 is feasible. That is, the body 2 and the cover 3 can be coupled by fitting the claw into the hole 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 give sufficient elasticity to the body 2 and the cover 3, and the snap fit as described above is performed. 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 adopting the assembly frame 5 which is a member different from the body 2 and the cover 3.

A plurality of insertion holes 311 are formed on the front surface of the cover 3, which is the front surface 31 of the wiring device 1. By inserting a pin or a blade of a plug of an electric device into the plurality of insertion holes 311, 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 fit a plug having a pair of power source poles (L pole and N pole) and a ground pole. is doing. The insertion hole 311 of each set is formed in a shape suitable for two types of plugs of A type and C type. The three insertion holes 311 of each set are arranged such that the pair of insertion holes 311 corresponding to the pair of power supply electrodes are arranged in the left-right direction, and the insertion holes 311 corresponding to the ground electrode are located above them. 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 body 4, which is the rear surface 23 of the wiring device 1. A terminal portion including a terminal plate and the like is housed in the body 4 at a position corresponding to the terminal hole 231. The terminal portion is a so-called quick-connect terminal of an electric wire insertion type in which the electric wire is connected by inserting the electric wire from the terminal hole 231. In the present embodiment, a total of three electric wires, that is, a pair of power supply lines and ground lines (earth lines) are connected to the wiring device 1. Further, 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 through the release operation hole 232, the electric wire holding state at the terminal portion is released.

As shown in FIG. 4, in the wiring device 1 according to the present embodiment, the cover 3 is larger than the body 2 in the left-right direction, that is, the cover 3 is wider. The body 2 and the cover 3 have substantially the same size in the vertical direction. FIG. 4 is a rear view of the wiring device 1 in which the assembly frame 5 is separated from the body 4 (body 2 and cover 3) as seen from the rear, and the shaded region (dot hatching) is the cover 3 Is represented.

That is, as shown in FIG. 4, the distance between the left and right end surfaces 32 (the left end surface and the right end surface) of the cover 3 is larger than the distance L1 between the left and right end surfaces 22 (the left end surface and the right end surface) of the body 2. The distance L2 is set large (L1<L2). Further, in this embodiment, since the body 4 is plane-symmetrical in the left-right direction, the left and right end surfaces 32 of the cover 3 protrude from the left and right end surfaces 22 of the body 2, and the both end surfaces of the cover 3 are protruded. 32 is located outside both end surfaces 22 of the body 2. In other words, a step is formed between the one end surface 32 of the cover 3 and the one end surface 22 of the body 2. Since the 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 from at least both sides of the body 2 in the second direction.

By the way, the assembly frame 5, together with the first protrusion 34 formed on the cover 3 and the second protrusion 24 formed on the body 2, a connecting structure 101 for connecting the body 2 and the cover 3 (see FIG. 4). ). That is, 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 one pair of coupling structures 101 is 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 in pairs on both end faces (left end face and right end face) of the body 4 in the left-right direction. The two pairs of coupling structures 101 are provided at the four corners of the body 4 when viewed from the front so as to be vertically aligned on each end surface (left end surface or right end surface) of the body 4 in the left-right direction. Therefore, the body 2 and the cover 3 are joined at the four corners of the body 4 when viewed from the front.

Specifically, the cover 3 has a first protrusion 34 protruding 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 has a second protrusion 24 that projects from one end surface 22 (left end surface or right end surface) of the body 2 in the left-right direction. The assembly frame 5 connects the body 2 and the cover 3 by being attached to the body 4 so as to hold the first protrusion 34 and the second protrusion 24 from both sides in the front-rear direction. In other words, the assembly frame 5 sandwiches the first protrusion 34 and the second protrusion 24 in the first direction in a state where the body 2 and the cover 3 are combined in the front-rear direction, so that the assembly frame 5 is separated from the first protrusion 34. The second protrusion 24 is prevented from being relatively separated. As a result, the opening between the body 2 and the cover 3 is prevented, and the body 2 and the cover 3 are joined together.

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 positioned slightly ahead of the four corners of the cover 3 viewed from the rear so that the first protrusion 34 provided on the cover 3 is not damaged. There is. That is, in such a case, the four corners of the cover 3 come into contact with the construction surface 800 before the first protrusions 34, and the first protrusions 34 required for joining the body 2 and the cover 3 are damaged. 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 (here, four) of the bonding structures 101 have a common configuration, the following description focuses on one bonding structure 101 unless otherwise specified, and the other bonding structures 101 have the same configuration. The description is omitted here. Here, attention is paid to the coupling structure 101 located at the upper right (the portion indicated by “A1” in FIG. 4) of the four corners when the wiring device 1 is viewed from the front. The arrows indicating the “front-back direction”, the “left-right direction”, and the “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, with respect to 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 has a first side portion 51, a second side portion 52, and a connecting side portion 53. The first side portion 51 and the second side portion 52 are arranged at regular intervals in the front-rear direction so that the first side portion 51 is on the front side. As will be described later in detail, 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). The second side portion 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 portion 53 connects the first side portion 51 and the second side portion 52.

In the present embodiment, the connecting side portion 53 has three crosspieces 531 arranged in the vertical direction. That is, the first side portion 51 and the second side portion 52 are connected by the three crosspieces 531. Here, the crosspieces 531 located on both sides in the vertical direction of the three crosspieces 531 connect the upper end portions of the first side portion 51 and the second side portion 52 in the vertical direction, and The lower end portions of the 51 and the second side portion 52 in the vertical direction are connected to each other. The central cross-section 531 of the three cross-sections 531 connects the vertical center parts 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 rail portions 531 on both sides of the three rail portions 531 are arranged so as to form a rectangular frame shape when viewed from one side in the left-right direction. There is. Further, a region surrounded by the first side portion 51, the second side portion 52, and the rail portions 531 on both sides of the three rail portions 531 is vertically separated by the central rail portion 531. A pair of assembly holes 54 are formed.

By the way, in the wiring device 1 according to the present embodiment, as described above, since the cover 3 is wider than the body 2 in the left-right direction, one end surface 32 of the cover 3 and one end surface of the body 2 are arranged. There is a step between 22 and 22. Therefore, the assembly frames 5 attached to the left and right end surfaces of the body 2 and the cover 3 adopt 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 offset from each other in the left-right direction. In short, the first side portion 51 on the side of the cover 3 is arranged on the outer side in the left-right direction compared to the second side portion 52 on the side of the body 2 so as to correspond to the cover 3 wider than the body 2. There is. The “outer side in the left-right direction” here means the side opposite to the center of the body 4 in the left-right direction, and is the “right side” 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 is "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 (crosspiece portion 531) has a shape in which the first side portion 51 side is positioned outside the second side portion 52 side in the left-right direction (right side in the example of FIG. 5C) with the step portion 534 as a boundary. Has been formed. Here, a surface of the first side portion 51 facing the cover 3 in the left-right direction (a left end surface in the example of FIG. 5C) and an end surface of the second side portion 52 in the left-right direction opposite to the body 2 (see the figure). In the example of 5C, the step portion 534 is provided so as to be flush with the right end surface).

In addition, the assembly frame 5 further includes a leg piece 55 that projects from a surface (left end surface in the example of FIG. 5C) that faces the body 2 and the cover 3 in the left-right direction. In this embodiment, the assembly frame 5 has a pair of leg pieces 55 arranged in the vertical direction. A hooking claw 551 that hooks at least one of the body 2 and the cover 3 is formed at the tip of each leg 55.

The assembly frame 5 further has a side wall 56 that covers a part of the pair of assembly holes 54 from the outside in the left-right direction. The side wall 56 does not completely cover the pair of assembly holes 54, but is formed so as to close only the first side portion 51 side of the pair of assembly holes 54 with the step portion 534 as a boundary. An outer surface in the left-right direction (a right end surface in the example of FIG. 5C) is formed flush with the side wall 56 and the first side portion 51. As will be described later in detail, when the assembly frame 5 is attached to the body 4, the side wall 56 abuts on the tip end surface of the first protrusion 34 in the left-right direction.

The assembly frame 5 also includes a device-side mounting portion 102 (see FIG. 5A) for mounting the body 4 on the mounting frame 8 (see FIG. 2). The device-side mounting portion 102 has a first mounting portion 57 and a second mounting portion 58. The first mounting portion 57 has a front surface 571 facing forward, and the second mounting portion 58 has a rear surface 581 facing rearward. The first mounting portion 57 and the second mounting portion 58 are arranged at different positions in the vertical direction.

In the present embodiment, the first mounting portion 57 has a pair of first mounting pieces 570 that are vertically separated. The second mounting portion 58 has a pair of second mounting pieces 580 that are vertically separated. The pair of first mounting pieces 570 is configured to project 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 mounting pieces 570 is provided at 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 is configured to project from the outer side surface (the right end surface in the example of FIG. 5C) of the assembly frame 5 in the left-right direction. Here, the pair of second mounting pieces 580 is provided at a position that straddles the first side portion 51, the crosspiece 531 and the side wall 56. Therefore, the first mounting portion 57 and the second mounting portion 58 are arranged at positions different from each other in the vertical direction so that the pair of second mounting pieces 580 are located inside the pair of first mounting pieces 570 in the vertical direction. Has been done.

Further, the second mounting 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) has an edge on the side opposite to the body 4 with respect to the edge on the body 4 side in the left-right direction (the left edge in the example of FIG. 5C). (The right edge in the example of FIG. 5C) is an inclined surface that is inclined so as to be located rearward. That is, the front surface 582 of the second mounting 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 rearward of the front surface 582 of the second mounting portion 58. When the front surface 582 of the second mounting portion 58 is an inclined surface as in the present embodiment, the first mounting portion 57 is more than the rear edge of the front surface 582 (the right edge in the example of FIG. 5C). The front surface 571 of the is located rearward. The device-side mounting portion 102 will be described in detail in the section "(2.4) Wiring device mounting structure to mounting frame".

Further, the assembly frame 5 has a plurality of press-fitting ribs 59 that project from the inner peripheral surfaces of the pair of assembly holes 54 toward the inside of the assembly holes 54. In the present embodiment, the first side portion 51, the second side portion 52, the connecting side portion 53, the leg piece 55, the side wall 56, the instrument side attachment portion 102 (the first attachment portion 57 and the second attachment portion 58). , And the plurality of press-fitting ribs 59 are integrally formed by resin molding.

As shown in FIG. 6, the assembly frame 5 configured in this manner is attached to the body 4 in a state where the body 2 and the cover 3 are combined in the front-rear direction. When the assembly frame 5 is attached to the 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 portion 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 portion 51 and the second side portion 52 in the front-rear direction. To do.

In other words, as shown in FIGS. 7A and 7B, by fitting the first protrusion 34 and the second protrusion 24 into the pair of assembly holes 54 in the assembly frame 5, the gap between the body 2 and the cover 3 is reduced. Is prevented from being opened, and as a result, the joined state of the body 2 and the cover 3 is maintained. At this time, the side wall 56 abuts on the tip surface of the first protrusion 34 in the left-right direction. That is, the tip end surfaces of the first protrusions 34 fitted in the pair of assembly holes 54 are butted against the side walls 56 that partially cover the pair of assembly holes 54 from the outside in the left-right direction.

Further, when the assembly frame 5 is attached to the 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. And is press-fitted into the assembly hole 54. As a result, the dimensional variation between the pair of assembly holes 54 and the first protrusion 34 and the second protrusion 24 can be absorbed by the deformation (plastic deformation) of the press-fitting ribs 59, and thus the container body 4 is removed. The rattling 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 the portion of the connecting side portion 53 on the first side portion 51 side of the step portion 534. In other words, of the pair of assembly holes 54, the press-fitting ribs 59 of the connecting side portions 53 are omitted in the portions where the outer openings in the left-right direction are closed by the side walls 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 distance between the adjacent crosspieces 531 is regulated by the side wall 56, so that the lateral side (on the side wall 56 side). The distance between adjacent crosspieces 531 in () does not change substantially. Therefore, if the press-fitting rib 59 is provided at a portion of the connecting side portion 53 closer to the first side portion 51 than the step portion 534, the assembly frame 5 is deformed so that the opening side (the inner side in the left-right direction) is opened. However, the attachment of the assembly frame 5 to the body 4 may be insufficient. On the other hand, in the configuration of the present embodiment, when the first protrusion 34 and the second protrusion 24 are press-fitted into the pair of assembly holes 54, the outer side in the left-right direction of the pair of assembly holes 54 is removed. It is possible to prevent the opening side (the inner side in the left-right direction) from opening at the portion where the opening is closed by the side wall 56.

By the way, as shown in FIG. 7A, the cover 3 further has an assembly groove 321 along the front-rear direction on the one end face 32 in the left-right direction. The connecting side portion 53 of the assembly frame 5 is configured to fit in the assembly groove 321. In the present embodiment, since the connecting side portion 53 is composed of the three crosspieces 531, the cover 3 is provided with three assembly grooves 321 corresponding thereto. In this embodiment, the three assembly grooves 321 are formed from the cover 3 to the body 2.

In addition, the first protrusion 34 has a pair of first protrusions 341 that are separated in the vertical direction by the center crosspiece 531 of the three crosspieces 531. Similarly, the second protrusion 24 has a pair of second protrusions 241 that are vertically separated from each other by the central rail 531 of the three rails 531. In other words, the first protrusion 34 is separated into the pair of first protrusions 341 by the central assembly groove 321 of the three assembly grooves 321. Similarly, the second protrusion 24 is separated into a pair of second protrusions 241 at the central assembly groove 321 of the three assembly grooves 321. As a result, when the assembly frame 5 is attached to the body 4, the one first projection 341 and the one second projection 241 are fitted into the one assembly hole 54, and the other assembly hole 54 and the other The first protrusion 341 and the other second protrusion 241 are fitted.

Further, 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 body 4. In the present embodiment, each of the pair of hooking holes 41 is formed so as to straddle the body 2 and the cover 3. The assembly frame 5 is attached to the body 4 such 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 projecting portion 34 and the second projecting portion 24 are press-fitted into the assembly hole 54, the assembly frame 5 does not easily come off from the body 4, but the assembly frame is formed by the pair of leg pieces 55. 5 becomes more difficult to fall off.

(2.3) Mounting Frame Next, the configuration of the mounting frame 8 will be described with reference to FIGS. 8A to 12B.

The mounting frame 8 includes a frame body 80 as shown in FIG. 8A. An opening window 81 is formed in the frame body 80 so as to penetrate the frame body 80 in the front-rear direction.

In addition, the wiring device 1 has device-side attachment portions 102 (assembly frames 5) at the four corners of the body 4 when viewed from the front. Therefore, the wiring device 1 according to the present embodiment is attached to the attachment frame 8 using the two pairs of frame-side attachment portions 6 located at both ends in the vertical direction among the three pairs of frame-side attachment portions 6.

In the present embodiment, at least one of the pair of vertical frames 83 is configured to be elastically deformable in the left-right direction over the entire width in the left-right direction. Therefore, the mounting frame 8 can temporarily enlarge the lateral dimension of the opening window 81. As a result, the wiring device 1 can be attached to and detached from the opening window 81.

Here, as shown in FIG. 9, a slit 833 extending in the up-down direction is formed in the right vertical frame 83 so that the right vertical frame 83 can be easily elastically deformed particularly in the left-right direction. Furthermore, a plurality of deformation preventing recesses 834 are formed on the front surfaces of the pair of vertical frames 83. With the decorative plate 9 (see FIG. 2) attached to the mounting frame 8, the deformation preventing projections 93 (see FIG. 2) protruding from the rear surface of the decorative plate 9 are inserted into the plurality of deformation preventing recesses 834 of the mounting frame 8. It As a result, in the state where the decorative plate 9 is attached, in the attachment frame 8, the deformation (elastic deformation) of the pair of vertical frames 83 is suppressed. Of the three deformation prevention recesses 834 formed in the right vertical frame 83, the deformation prevention recesses 834 on both sides in the vertical direction are connected to the slit 833.

The reinforcing member 72 further has a third portion 723 that connects the first portion 721 and the second portion 722. The third portion 723 has a shape that is bulged forward along the bulged portion 837.

In the present embodiment, the first part 721, the second part 722 and the third part 723 are integrally formed. Specifically, the reinforcing member 72 has a pair of metal plates 720. Each of the pair of metal plates 720 has a first portion 721, a second portion 722, and a third portion 723. That is, the reinforcing member 72 is not a single metal plate integrally formed as a whole, but is composed of a pair of physically separated metal plates 720. Here, each of the pair of metal plates 720 is not in a flat plate shape, but is formed in a three-dimensional shape by the third portion 723 protruding forward.

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

Has been formed. Accordingly, when the fixing screw is tightened through the first fixing hole 85, a force from the fixing screw acts on a portion of the reinforcing member 72 on the opposite side of the opening window 81 from the first fixing hole 85, and thus the reinforcing member 72. The moment acting on can be suppressed to a small value.

Next, the frame-side mounting portion 6 of the mounting frame 8 will be described in more detail with reference to FIGS. 12A and 12B. In FIG. 12B, the assembly frame 5 is shown by an imaginary line (two-dot chain line). Since a plurality of (six in this case) frame-side mounting portions 6 have a common configuration, the following description will focus on one frame-side mounting portion 6 unless otherwise specified, and regarding the other frame-side mounting portions 6. The description is omitted because they have the same configuration. Here, when the mounting frame 8 is viewed from the front, the frame-side mounting portion 6 located at the upper right (the portion indicated by “A2” in FIG. 12A) of the four corners is focused on.

As shown in FIG. 12B, the frame side attachment portion 6 has a first regulation portion 61 and a second regulation portion 62.

Further, a release recess 835 is formed on the inner side surface 831 of the right vertical frame 83 facing the opening window 81 side. The release recess 835 is a recess that is open to the front and the opening window 81 side. Here, three release recesses 835 are formed in the right vertical frame 83 so as to be located between the pair of restriction recesses 832. The release recess 835 is used to insert the tip of a jig such as a driver when the wiring device 1 is removed from the mounting frame 8 to bend (elastically deform) the right vertical frame 83 to the right.

The second restricting portion 62 also has a rear surface 622 (see FIG. 8B) facing rearward. The rear surface 611 of the first restriction portion 61 is located in front of the rear surface 622 of the second restriction portion 62.

Furthermore, the frame-side mounting portion 6 further has a dowel 612 (see FIG. 9) protruding from at least one of the rear surface 611 of the first restriction portion 61 and the front surface 621 of the second restriction portion 62. In the present embodiment, the dowel 612 is provided on the rear surface 611 of the first restricting portion 61. Although details will be described later, when the wiring device 1 is attached to the frame body 80, the dowel 612 is plastically deformed by being crushed by the wiring device 1.

As will be described later in detail, when the wiring device 1 is attached to the frame body 80, the rear surface of the reinforcing rib 613 facing the rear side does not contact the wiring device 1.

(2.4) Mounting Structure of Wiring Device to Mounting Frame Next, a mounting structure for mounting the wiring device 1 to the mounting frame 8 (device-side mounting portion 102 and frame-side mounting portion 6) will be described with reference to FIGS. Will be described in more detail with reference to. Hereinafter, unless otherwise specified, one attachment structure (apparatus-side attachment portion 102 and frame-side attachment portion 6) will be focused on, and other attachment structures will not be described because they have the same configuration. Here, pay attention to the mounting structure (apparatus-side mounting portion 102 and frame-side mounting portion 6) located at the upper right (the portion indicated by “A3” in FIG. 13) of the four corners when the wiring device 1 is viewed from the front. And Therefore, for example, with respect to the mounting structure located at the upper left of the four corners when the wiring device 1 is viewed from the front, the left and right are opposite to the following description.

As shown in FIGS. 13 and 14, the wiring device 1 is attached to the attachment frame 8 with at least the cover 3 inserted into the opening window 81 of the attachment frame 8. Here, when the wiring device 1 is attached to the mounting frame 8, the wiring device 1 is mounted so as to be inserted into the opening window 81 from the rear of the mounting frame 8. At this time, the worker first fits the second mounting portion 58, which is a mounting claw provided on the left side assembly frame 5 of the wiring device 1, into the restriction recess 832 of the vertical frame 83 on the left side of the mounting frame 8. Subsequently, the worker pushes the right end portion of the wiring device 1 from the rear to bend the vertical frame 83 on the right side of the mounting frame 8 to the right, and is installed on the assembly frame 5 on the right side of the wiring device 1. The second mounting portion 58 serving as a mounting claw is fitted into the regulation recess 832 of the vertical frame 83 on the right side of the mounting frame 8.

Here, the wiring device 1 and the mounting frame 8 are connected to each other within the dimensions of the mounting frame 8 in the front-rear direction. Further, as shown in FIG. 15, the attachment frame 8 is attached to the construction surface 800 such that the rear surface of the frame body 80 contacts the surface of the construction surface 800. Therefore, the amount of protrusion of the mounting frame 8 from the construction surface 800 is due to the dimensions of the mounting structure (apparatus-side mounting portion 102 and frame-side mounting portion 6) in the front-rear direction, and the dimension of the mounting structure in the front-rear direction is suppressed. If so, the amount of protrusion of the mounting frame 8 from the construction surface 800 can be suppressed. FIG. 15 is a bottom view of the wiring device 1 attached to the attachment frame 8 as seen from below, in which a shaded region represents the cover 3. In FIG. 15, the construction surface 800 is shown by an imaginary line (two-dot chain line).

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

When the wiring device 1 is mounted on the mounting frame 8, as shown in FIG. 16, the first mounting portion 57 and the second mounting portion 58 of the device-side mounting portion 102 are the first restriction in the frame-side mounting portion 6. The wiring device 1 is fixed by coming into contact with the portion 61 and the second restriction portion 62. That is, the instrument-side mounting portion 102 has the front surface 571 of the first mounting portion 57 contacting the mounting frame 8 from the rear side, and the rear surface 581 of the second mounting portion 58 contacting the mounting frame 8 from the front side. The movement of the body 4 in the front-rear direction with respect to 8 is restricted. In other words, the frame-side mounting portion 6 has the rear surface 611 of the first restricting portion 61 contacting the wiring device 1 from the front, and the front surface 621 of the second restricting portion 62 contacting the wiring device 1 from the rear, so that The movement of the wiring device 1 in the front-rear direction with respect to the main body 80 is restricted.

Specifically, as shown in FIG. 17A, the instrument-side mounting portion 102 includes a front surface 571 (see FIG. 5A) of the first mounting portion 57 (a pair of first mounting pieces 570) that is located in the frame-side mounting portion 6. The 1st regulation part 61 (a pair of 1st regulation piece 610) is made to contact the rear surface 611 (refer FIG. 12B). As a result, the wiring device 1 is restricted from moving forward relative to the frame body 80. At this time, the dowel 612 formed on the rear surface 611 of the first restriction portion 61 is crushed by the front surface 571 of the first mounting portion 57 and plastically deformed. Therefore, even if there is a slight dimensional error between the device-side mounting portion 102 and the frame-side mounting portion 6, the plastic deformation of the dowel 612 can absorb the influence of this dimensional error, and the wiring device 1 with respect to the mounting frame 8 can be absorbed. Rattling is suppressed. Further, in this state, the front surface 571 of the first mounting portion 57 contacts only the rear surface 611 of the first restriction 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 includes a rear surface 581 (see FIG. 5A) of the second mounting portion 58 (a pair of second mounting pieces 580) that is the second restriction in the frame-side mounting portion 6. The front surface 621 (see FIG. 12B) of the portion 62 (a pair of second restricting pieces 620) is brought into contact. As a result, the wiring device 1 is restricted from moving rearward relative to the frame body 80. Therefore, 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. Is almost the same as the size. Therefore, the movement of the body 4 with respect to the mounting frame 8 is restricted in both the vertical direction and the horizontal direction. Furthermore, by sandwiching both vertical walls of the release recess 835 between the pair of second mounting pieces 580, movement of the body 4 with respect to the mounting frame 8 in the vertical direction may be restricted.

By the way, as described above, in the wiring device 1 which is mounted on the construction surface 800 (see FIG. 1) using the mounting frame 8, wiring is performed at the time of construction of the wiring device 1 (at the time of mounting) or when the wiring device 1 is used. A relatively large force may act on the device 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 frame 1 is pushed forward with respect to the wiring device 1 from the wiring or the like connected to the wiring device 1. Power acts. In addition, when the wiring device 1 is used, the power cord is pulled out to pull out the plug, that is, when the power cord is caught by a person's foot or the like, that is, when the power cord is caught by a person's foot, etc. The force that pulls forward acts. Furthermore, when the wiring device 1 is used, when inserting the plug, a force is applied to the wiring device 1 in a direction of pushing the wiring device 1 backward. 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, so Tatsuki is suppressed.
