(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 to supply power to the electric device. Here, as the wiring device 1, a two-port type outlet that is for AC 220 V with a ground electrode and can simultaneously connect two plugs will be illustrated. Moreover, in this embodiment, the wiring tool 1 for indoors attached to the wall of a building is illustrated as the wiring tool 1. The building in which the wiring device 1 is installed is, for example, a detached house, an apartment house, an office, a store, a care facility, or the like.

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

  Furthermore, the decorative plate 9 is attached to the mounting frame 8. The decorative plate 9 is made of synthetic resin. The decorative plate 9 is in the shape of a rectangular frame having an opening 91. The decorative plate 9 is attached to the mounting frame 8 so as to cover substantially the entire mounting frame 8 from the front surface of the mounting frame 8 to the circumferential surface of the mounting frame 8. On the rear surface of the decorative plate 9, a plurality of (four in the example of FIG. 2) hooking protrusions 92 projecting rearward are formed. The decorative plate 9 is held on the mounting frame 8 by hooking the plurality of hook 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 in accordance with the shape of the front surface 31 of the wiring device 1. Therefore, even when the decorative plate 9 is attached to the mounting frame 8, the front surface 31 of the wiring device 1 is exposed forward 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 components. Furthermore, the decorative plate 9 may or may not be included in the components of the wiring device system 10. Furthermore, the wiring fixture 1 which comprises the wiring fixture system 10 with the attachment frame 8 may be not only an outlet but a switch etc., for example.

  By the way, as shown in FIG. 2, the wiring apparatus 1 according to the present embodiment is combined with the body 2 so as to cover the opening surface 21 of the body 2 and the body 2 having the opening surface 21 (see FIG. 3) on the front surface. And a cover 3. The body 2 and the cover 3 constitute the body 4 in a state where they are combined with each other. The housing 4 accommodates 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 (here, four) assembly frames 5. In other words, the wiring apparatus 1 includes the body 4 including the body 2 and the cover 3 and a plurality of assembly frames 5 for connecting the body 2 and the cover 3.

  In the wiring device 1 according to this embodiment, the cover 3 is 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 wider than the body 2 in the second direction. In other words, both end surfaces 32 (see FIG. 4) orthogonal to the second direction in the cover 3 are located outside the both end surfaces 22 (see FIG. 4) orthogonal to the second direction in the body 2. Here, when both end surfaces 32 in the second direction of the cover 3 are located outside of both end surfaces 22 in the second direction of the body 2, both end surfaces 32 of the cover 3 are both end surfaces 22 of the body 2 in the second direction. It means that it is not between (that is, inside) but outside the end faces 22. Thereby, the dimension in the second direction of the wiring device 1 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 (in 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 case of the wiring device 1, with the wiring device 1 attached to the work surface 800, the dimensions of the portion to be accommodated in the wall (in the embedding box) can be increased while the dimensions of the portion exposed forward are enlarged. 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 where the user performs an operation (plugging and unplugging in the case of the outlet) when using the wiring device 1. Thus, the operability and the design of the wiring device 1 are improved. Furthermore, when the wiring device 1 is an outlet, 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 are enlarged by increasing the dimensions of the front surface 31. It also leads to an increase in the insulation distance between In particular, when the decorative plate 9 is made of metal, the increase of the insulation distance between the insertion hole 311 and the decorative plate 9 is useful. On the other hand, by reducing the dimensions of the portion of the wiring device 1 that fits in the wall (in the embedding box), a space can be made in the space around the wiring device 1 in the wall, and a space for storing wiring etc. It becomes easy to secure.

  Thus, in the wiring device 1 according to the present embodiment, the body 2 and the cover 3 having different dimensions in at least the second direction are coupled to each other by the plurality of assembly frames 5. A 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 in the second direction in the housing 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 on 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 in the housing 4, and at least a pair of device side mounting portions 102 are realized by the assembly frame 5. . The plurality of assembly frames 5 have a pair of second attachment portions 58 (see FIG. 2) as at least a pair of attachment claws projecting from both end faces in the second direction of the wiring device 1 (container 4). At least a pair of restriction recesses 832 (see FIG. 2) are formed in the mounting frame 8 at positions corresponding to the at least one pair of second mounting portions 58 on the inner side surface of the opening window 81. The wiring device 1 is attached to the attachment frame 8 in a state in which at least one pair of second attachment portions 58 is inserted into at least one pair of restriction recesses 832.

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

  In the present embodiment, with the wiring fixture 1 attached to the wall surface of the building, which is the construction surface 800, the direction orthogonal to the construction surface 800 is referred to as "front-back direction", and the front surface 31 of the wiring fixture 1 is directed. The side is described as "forward". In addition, a direction that is orthogonal to the front and rear direction and parallel to the horizontal surface is referred to as “left and right direction”, and the right side is referred to as “right” and the left side is referred to as “left”. . Furthermore, a direction perpendicular to both the longitudinal direction and the lateral direction, that is, a direction perpendicular (perpendicular) to the horizontal surface is referred to as “vertical direction”, and the wiring device 1 is viewed from the front as “downward (vertical direction) It explains as ". Thus, when each direction is defined, "front-back direction" corresponds to "first direction", "left-right direction" corresponds to "second direction", and "vertical direction" corresponds to "third direction". Arrows indicating “front-rear direction”, “left-right direction”, and “up-down direction” in the drawings are only shown for the purpose of explanation and do not have any substance.

  However, these directions are not the meaning which limits the use direction of the wiring fixture 1. For example, when the wiring device 1 is attached to a floor surface instead of a wall surface, the first direction (longitudinal direction) is a direction perpendicular to the horizontal plane, and the second direction (horizontal direction) and the third direction (vertical direction) Is a direction parallel to the horizontal plane. In addition, even when the wiring device 1 is mounted on a wall surface, the “left and right direction” is a horizontal surface by mounting the wiring device 1 on the wall surface in the direction in which the “vertical direction” is parallel to the horizontal surface (that is, horizontal). It is vertical.

(2.1) Wiring fixture First, the configuration of the wiring fixture 1 will be described with reference to FIGS.

  The wiring apparatus 1 includes the body 2, the cover 3, and the assembling frame 5 as described above. The assembly frame 5 is a member for connecting the body 2 and the cover 3. In the present embodiment, in order to connect the body 2 and the cover 3 at four locations, the wiring apparatus 1 includes four assembly frames 5. Since a plurality of (four in this case) assembly frames 5 have a common configuration, one assembly frame 5 will be described hereinafter unless otherwise noted, and the other assembly frames 5 are described as having the same configuration. Omit.

  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 which 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 opposite surface to the body 2, that is, the rear surface. Similarly to the opening surface 21 of the body 2, the opening surface 33 of the cover 3 is formed in a rectangular shape long in the vertical direction. However, in the present embodiment, since the cover 3 is wider than the body 2 in the left-right direction (second direction), the dimension of the opening surface 33 of the cover 3 in the second direction is slightly smaller than that of 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 portion in the vertical direction of the peripheral wall of the body 2 surrounding the opening surface 21 is formed in a convex shape projecting forward. According to this convex shape, the central portion 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 the body 4 by being coupled to each other. In the present embodiment, the housing 4 is formed to be plane-symmetrical 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, the internal space of the housing 4. In short, the wiring apparatus 1 includes the body 4 including the body 2 and the cover 3 which can be separated from each other, and the body 2 and the assembly frame 5 are used to store the internal components in the internal 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 instrument body 40 (see FIG. 2) is also provided with a body 2 and a cover 3 which are part of the wiring instrument 1 and are connected to each other by an assembly frame 5. The instrument body 40 includes internal components in addition to the container 4 (body 2 and cover 3). That is, the wiring device 1 is configured by the device body 40 and the assembly frame 5. However, illustration of the internal parts accommodated in the container 4 is abbreviate | omitted in all the drawings.

  Here, the body 2, the cover 3 and the assembly frame 5 are all made of an electrically insulating synthetic resin. The body 2 and the cover 3 constituting the container 4 for housing the internal parts are made of, for example, a thermosetting resin having excellent tracking resistance, such as urea resin (urea resin). On the other hand, the assembly frame 5 is made of, for example, 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 nail may be provided on one of the body 2 and the cover 3 and a hole in which the nail is fitted may be provided on the other. Coupling of 2 and cover 3 is feasible. That is, the body 2 and the cover 3 can be connected 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 impart sufficient elasticity to the body 2 and the cover 3 and the snap fit as described above Structure is difficult to adopt. Therefore, in the wiring device 1 according to the present embodiment, the connection of the body 2 and the cover 3 is realized by adopting the assembly frame 5 which is a separate member from the body 2 and the cover 3.

  A plurality of insertion holes 311 are formed on the front surface of the cover 3 to be the front surface 31 of the wiring device 1. The plug pin or blade of the electrical device is inserted into the plurality of insertion holes 311 to electrically connect the plug to the wiring device 1. Here, as shown in FIG. 2, the wiring apparatus 1 has two sets of three insertion holes 311 so as to fit in a plug having a pair of power supply poles (L and N poles) and a ground pole. doing. Each set of insertion holes 311 is formed in a shape adapted to two types of plugs of A type and C type. The three insertion holes 311 in each set are arranged such that a pair of insertion holes 311 corresponding to the pair of power supply electrodes are aligned in the left-right direction, and the insertion holes 311 corresponding to the ground electrode are located above them. Furthermore, the two sets of insertion holes 311 are arranged in the vertical direction.

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

  In the wiring device 1 according to the present embodiment, as shown in FIG. 4, the cover 3 is larger than the body 2 in the left-right direction, that is, the cover 3 is 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 apparatus 1 in a state in which the assembly frame 5 is separated from the housing 4 (body 2 and 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 L1 between the left and right end faces 22 (left end face and right end face) of the body 2 is greater than the distance L1 between the left and right end faces 32 (left end face and right end face) of the cover 3. The distance L2 is set large (L1 <L2). Furthermore, in the present embodiment, since the body 4 is plane-symmetrical in the left-right direction, both end surfaces 32 in the left-right direction of the cover 3 protrude from both end surfaces 22 in the left-right direction of the body 2. 32 are located outside of the end faces 22 of the body 2. In other words, a step is generated between one end face 32 of the cover 3 and one end face 22 of the body 2. Since the housing 4 has a symmetrical shape in the left-right direction, the distance from one end face 32 of the cover 3 to one end face 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 projection 34 formed on the cover 3 and a second projection 24 formed on the body 2 as well as a coupling structure 101 for coupling the body 2 and the cover 3 (see FIG. 4). Configure). That is, the coupling structure 101 is configured by one assembly frame 5, the first projection 34 of the cover 3, and the second projection 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 on both end surfaces (left end surface and right end surface) of the container 4 in the left-right direction. The two pairs of coupling structures 101 are provided at the four corners of the body 4 as viewed from the front so as to be vertically aligned on the respective end faces (left end face or right end face) of the body 4 in the left-right direction. Therefore, the body 2 and the cover 3 are combined at the four corners of the body 4 viewed from the front.

  Specifically, the cover 3 has 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 has a second projection 24 projecting 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 couples the body 2 and the cover 3 by being attached to the housing 4 so as to hold the first projection 34 and the second projection 24 from both sides in the front-rear direction. In other words, the assembly frame 5 holds the first projection 34 and the second projection 24 by sandwiching the first projection 34 and the second projection 24 in the first direction in a state where the body 2 and the cover 3 are combined in the front-rear direction. It prevents that the 2nd projection 24 separates relatively. Thereby, the opening between the body 2 and the cover 3 is prevented, and the body 2 and the cover 3 are coupled.

  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 contacts the construction surface 800. In such a case, the rear surface of the first projection 34 is positioned slightly forward as compared to the four corners of the cover 3 viewed from the rear so that the first projection 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 work surface 800 before the first projection 34, and the breakage of the first projection 34 necessary for the connection of 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 of (four in this case) bonding structures 101 have a common configuration, the following description will focus on one bonding structure 101 unless otherwise noted, and the other bonding structures 101 have the same configuration. The explanation is omitted. Here, when the wiring device 1 is viewed from the front, attention is focused on the coupling structure 101 located at the upper right (the portion indicated by “A1” in FIG. 4) among the four corners. The arrows indicating “front and back direction”, “left and right direction”, and “up and down direction” in FIGS. 5A to 7B are also described based on the upper right bonding structure 101 among the four corners. Therefore, for example, the left and right of the coupling structure 101 located at the upper left of the four corners when the wiring device 1 is viewed from the front is opposite to the description below.

  As shown in FIGS. 5A to 5C, the assembly frame 5 in the connecting structure 101 has a first side 51, a second side 52, and a connecting side 53. The first side 51 and the second side 52 are arranged at a constant distance in the front-rear direction such that the first side 51 is on the front side. Although the details will be described later, 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 52 contacts the second protrusion 24 from the opposite side (that is, the rear side) to the first protrusion 34 in the front-rear direction. The connecting side portion 53 connects the first side portion 51 and the second side portion 52.

  In the present embodiment, the connection side portion 53 includes three cross bars 531 aligned in the vertical direction. That is, the first side 51 and the second side 52 are connected by three cross bars 531. Here, the crosspieces 531 positioned on both sides in the vertical direction among the three crosspieces 531 connect the upper ends of the first side 51 and the second side 52 in the vertical direction, and the first side The lower end portions in the vertical direction of the second side portion 52 are connected to each other. Of the three crosspieces 531, the crosspieces 531 at the center connect central parts of the first side 51 and the second side 52 in the vertical direction. In other words, the first side 51, the second side 52, and the bars 531 on both sides of the three bars 531 are arranged to form a rectangular frame as viewed from one side in the left-right direction. There is. Furthermore, in a region surrounded by the first side 51, the second side 52, and the cross bars 531 on both sides of the three cross bars 531, the central cross bars 531 are vertically separated. 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 face 32 of the cover 3 and one end face of the body 2 There is a step between it and 22. Therefore, the assembly frame 5 attached to the left and right direction end faces of the body 2 and the cover 3 adopts the configuration described below in order to conform to such a step.

  That is, the first side portion 51 and the second side portion 52 are disposed to be shifted from each other in the left-right direction. In short, the first side 51 on the cover 3 side is disposed outside in the left-right direction as compared to the second side 52 on the body 2 side so as to correspond to the cover 3 wider than the body 2 There is. Here, “outside in the left-right direction” means the side opposite to the center of the body 4 in the left-right direction, and becomes “right” in the assembly frame 5 attached to the right end face of the body 4 In the assembly frame 5 attached to the left end face of 4, it becomes "left side". Specifically, a stepped portion 534 is formed in part of the connecting side portion 53 in the front-rear direction. In the connecting side 53 (the cross 531), the first side 51 is located on the outer side in the left-right direction (right side in the example of FIG. 5C) than the second side 52 with the stepped portion 534 as a boundary. It is formed. Here, of the first side 51, the surface facing the cover 3 in the left-right direction (left end surface in the example of FIG. 5C), and the end surface of the second side 52 opposite to the body 2 in the left-right direction A stepped portion 534 is provided so as to be flush with the right end surface in the example of 5C.

  In addition, the assembly frame 5 further includes a leg 55 that protrudes from a surface (left end surface in the example of FIG. 5C) facing the body 2 and the cover 3 in the left-right direction. In the present embodiment, the assembly frame 5 has a pair of leg pieces 55 aligned in the vertical direction. At the tip of each leg 55, a hook 551 is formed which is hooked on at least one of the body 2 and the cover 3.

  Further, the assembly frame 5 further includes a side wall 56 which 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, and is formed so as to close only the first side 51 side of the pair of assembly holes 54 with the step portion 534 as a boundary. In the side wall 56 and the first side portion 51, an outer surface in the left-right direction (right end surface in the example of FIG. 5C) is formed flush. Although the details will be described later, in the state where the assembly frame 5 is attached to the housing 4, the side wall 56 is butted to the tip end surface of the first projection 34 in the left-right direction.

  Further, the assembly frame 5 includes an instrument side attachment portion 102 (see FIG. 5A) for attaching the container 4 to the attachment frame 8 (see FIG. 2). The instrument side attachment portion 102 has a first attachment portion 57 and a second attachment 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 attachment portion 57 and the second attachment portion 58 are arranged at mutually different positions in the vertical direction.

  In the present embodiment, the first attachment portion 57 has a pair of first attachment pieces 570 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 mounting pieces 570 are 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 attachment pieces 570 is provided in the cross section 531 at a portion closer to the first side 51 than the stepped portion 534. The pair of second attachment pieces 580 are configured to protrude from the outer surface (the right end surface in the example of FIG. 5C) in the left-right direction of the assembly frame 5. Here, the pair of second attachment pieces 580 is provided at a position straddling the first side portion 51, the bar portion 531, and the side wall 56. Therefore, the first mounting portion 57 and the second mounting portion 58 are disposed at mutually 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. It is done.

  Furthermore, 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 end edge on the side opposite to the body 4 than the end edge on the side of the body 4 (left end edge in the example of FIG. 5C) in the left-right direction (The right end edge in the example of FIG. 5C) is an inclined surface inclined so as to be located rearward. That is, the front surface 582 of the second attachment portion 58 is an inclined surface 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 closer than the end edge (the right end edge in the example of FIG. The front 571 of the is located at the rear. The device side mounting portion 102 will be described in detail in the section “(2.4) Mounting structure of wiring device on mounting frame”.

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

  The assembly frame 5 configured in this manner is attached to the housing 4 in a state where the body 2 and the cover 3 are combined in the front-rear direction, as shown in FIG. In a state where the assembly frame 5 is attached to the housing 4, the first side portion 51 contacts the first protrusion 34 from the opposite side (i.e., the front side) to the second protrusion 24 in the front-rear direction. Similarly, the second side 52 contacts the second protrusion 24 from the opposite side (that is, the rear side) to the first protrusion 34 in the front-rear direction. Therefore, the assembly frame 5 couples the body 2 and the cover 3 by sandwiching the first projection 34 and the second projection 24 between the first side 51 and the second side 52 in the front-rear direction. Do.

  In other words, as shown in FIGS. 7A and 7B, the first projection 34 and the second projection 24 are fitted into the pair of assembly holes 54 in the assembly frame 5, whereby the space between the body 2 and the cover 3 is obtained. Opening is prevented, and as a result, the coupled state of the body 2 and the cover 3 is maintained. At this time, the side wall 56 abuts on the end surface of the first protrusion 34 in the left-right direction. That is, the front end surface of the first projection 34 fitted in the pair of assembly holes 54 abuts against the side wall 56 covering a part of the pair of assembly holes 54 from the outside in the left-right direction.

  Furthermore, in a state where the assembly frame 5 is attached to the housing 4, the first projection 34 and the second projection 24 crush a plurality of press-fit ribs 59 formed on the inner peripheral surface of the assembly hole 54. Then, it is pressed into the assembly hole 54. Thereby, dimensional variation between the pair of assembly holes 54 and the first projection 34 and the second projection 24 can be absorbed by the deformation (plastic deformation) of the press-in rib 59. The rattling of the assembly frame 5 is suppressed.

  Here, in the present embodiment, the plurality of press-fit ribs 59 are provided in the connecting side portion 53 so as to avoid the portion closer to the first side portion 51 than the step portion 534. In other words, with respect to the portion of the pair of assembly holes 54 in which the opening in the lateral direction is closed by the side wall 56, the press-fit rib 59 of the connection side portion 53 is omitted. That is, in the portion on the side closer to the first side 51 than the step portion 534 of the connection side 53, the distance between the adjacent cross bars 531 is restricted by the side wall 56, so the lateral side (the side 56 side) The spacing between the adjacent crosspieces 531 in (1) does not change substantially. Therefore, if the press-in rib 59 is provided at a portion closer to the first side 51 than the step portion 534 in the connecting side 53, the assembly frame 5 is deformed so that the opening side (inner side in the left-right direction) opens. As a result, the attachment of the assembly frame 5 to the container 4 may be insufficient. On the other hand, in the configuration of the present embodiment, when the first projection 34 and the second projection 24 are press-fitted into the pair of assembly holes 54, the outside of the pair of assembly holes 54 in the left-right direction is obtained. In the portion where the opening is closed by the side wall 56, the opening side (inner side in the left-right direction) can be prevented from opening.

  By the way, as shown to FIG. 7A, the cover 3 further has the assembly groove 321 along the front-back direction in the end surface 32 of the left-right direction. The connection side 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 three cross bars 531, three assembling grooves 321 are formed in the cover 3 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 which are vertically separated at the center cross section 531 among the three cross sections 531. Similarly, the second protrusion 24 has a pair of second protrusions 241 which are vertically separated at the center cross section 531 among the three cross sections 531. In other words, the first protrusion 34 is separated into a pair of first protrusions 341 at a central assembly groove 321 among the three assembly grooves 321. Similarly, the second projection 24 is separated into a pair of second projections 241 at a central assembly groove 321 among the three assembly grooves 321. Thereby, in a state where the assembly frame 5 is attached to the housing 4, one first projection 341 and one second projection 241 fit into one assembly hole 54, and the other assembly hole 54 into the other assembly hole 54. One protrusion 341 and the other second protrusion 241 are fitted.

  Further, a pair of hooking 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 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 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 projection 34 and the second projection 24 are press-fit into the assembly hole 54, the assembly frame 5 is configured so as not to be easily detached from the container 4, but the assembly frame is formed by the pair of leg pieces 55. 5 becomes more difficult to drop off.

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

  The attachment frame 8 is provided with the frame main body 80, as shown to FIG. 8A. The frame main body 80 is formed with an opening window 81 penetrating the frame main body 80 in the front-rear direction. The opening window 81 is formed in a rectangular shape which is long in the vertical direction. The frame main body 80 has a pair of vertical frames 83 facing each other through the opening window 81 in the left-right direction, and a pair of horizontal frames 84 facing each other through the opening window 81 in the vertical direction. A pair of vertical frames 83 connect between the left and right ends of one (upper) horizontal frame 84 in the pair of horizontal frames 84 and the left and right ends of the other (lower) horizontal frame 84. ing. That is, the frame main body 80 is formed in a rectangular frame shape surrounding the opening window 81 by the pair of vertical frames 83 and the pair of horizontal frames 84.

  Each of the pair of horizontal frames 84 has an oblong first fixing hole 85 and a second fixing hole 86. The first fixing hole 85 penetrates the mounting frame 8 in the front-rear direction, and is a hole for passing a fixing screw for fixing the mounting frame 8 to the embedding box or the like. The second fixing hole 86 penetrates the mounting frame 8 in the front-rear direction, and is a hole for passing a fixing screw for directly attaching the mounting frame 8 to the construction surface 800.

  The wiring device 1 is attached to the frame main body 80 by inserting the wiring device 1 into the opening window 81 of the frame main body 80. The frame main body 80 has at least a pair of frame side attachment portions 6 (see FIG. 8B) provided on both sides of the opening window 81 in the left and right direction. At least a pair of frame-side attachment parts 6 together with an instrument-side attachment part 102 provided in the wiring apparatus 1 constitute an attachment structure for attaching the wiring apparatus 1 to the attachment frame 8 and provided in a pair of vertical frames 83 It is done. That is, the mounting structure is configured by the instrument side mounting portion 102 and the frame side mounting portion 6.

  In the present embodiment, a mounting frame 8 for three pieces to which up to three container bodies 4A (see FIG. 18) of unit dimensions to be described later (see FIG. 18) can be aligned in the vertical direction is illustrated. The mounting frame 8 has three pairs (three sets) of frame-side mounting portions 6, and can be mounted to any number of one to three ranges of container bodies 4A of unit dimensions. In the present embodiment, the housing 4 has a size corresponding to a size in which three housings 4A of unit size are vertically arranged. Moreover, the wiring device 1 has the device side attachment part 102 (assembly frame 5) in the four corners of the container 4 seen from the front. Therefore, the wiring device 1 according to the present embodiment is attached to the mounting frame 8 by using two pairs of frame side mounting portions 6 positioned at both ends in the vertical direction among the three pairs of frame side mounting 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 expand the dimension of the opening window 81 in the left-right direction. Thereby, attachment and detachment of the wiring fixture 1 with respect to the opening window 81 are attained.

  Here, as shown in FIG. 9, slits 833 extending in the vertical direction are formed in the right vertical frame 83 so that the right vertical frame 83 is easily elastically deformed in the left and right direction. Furthermore, on the front surface of the pair of vertical frames 83, a plurality of deformation preventing recesses 834 are formed. In a state where the decorative plate 9 (see FIG. 2) is 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. Ru. Thus, in the mounting frame 8, deformation (elastic deformation) of the pair of vertical frames 83 is suppressed in the state in which the decorative plate 9 is attached. Of the three deformation preventing recesses 834 formed in the right vertical frame 83, the deformation preventing recesses 834 on both sides in the vertical direction are connected to the slit 833.

  By the way, the frame main body 80 is comprised by the resin frame 71 and the reinforcement member 72, as shown in FIG.

  The resin frame 71 is made of synthetic resin having electrical insulation. The resin frame 71 is made of, for example, a thermoplastic resin such as ABS resin, PC (polycarbonate), or PBT (polybutylene terephtalate). The resin frame 71 includes a pair of vertical frames 83 and a pair of horizontal frames 84, and the pair of vertical frames 83 and the pair of horizontal frames 84 form a rectangular frame surrounding the opening window 81. Here, the pair of vertical frames 83 includes root portions 836 connected to the pair of horizontal frames 84. In the present embodiment, since each of the pair of vertical frames 83 includes the pair of root portions 836 connected to the pair of horizontal frames 84, the resin frame 71 includes a total of four root portions 836.

  The reinforcing member 72 is made of, for example, a metal material such as a zinc steel plate (galvanized steel plate). The reinforcing member 72 is fixed to the resin frame 71. The reinforcing member 72 is a member for reinforcing the resin frame 71. 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 the front in the resin frame 71. The reinforcing member 72 includes a first portion 721 located in front of the pair of horizontal frames 84, and a second portion 722 located in front of the root portion 836 connected to at least the pair of horizontal frames 84 of the pair of vertical frames 83; Have.

  Furthermore, each root portion 836 of the pair of vertical frames 83 has a raised portion 837 that protrudes forward at the end on the opening window 81 side in the left-right direction. The reinforcing member 72 further includes a third portion 723 connecting the first portion 721 and the second portion 722. The third portion 723 has a shape that bulges forward along the ridge 837.

  In the present embodiment, the first portion 721, the second portion 722, and the third portion 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 constituted by a single piece of metal plate integrated as a whole, but by a pair of physically separated metal plates 720. Here, each of the pair of metal plates 720 is not flat, and 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, on each vertical frame 83 of the resin frame 71, a plurality of (here, two) caulking protrusions 712 protruding from the front surface 711 are formed. The second portion 722 of the reinforcing member 72 is formed with a plurality of (here, two) caulking holes 724 penetrating 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 plurality of caulking projections 712 in a state where the plurality of caulking projections 712 are inserted into the plurality of 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. The first portion 721 of the reinforcing member 72 is formed with a plurality of (here, four) caulking holes 726 penetrating 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 plurality of caulking projections 714 in a state where the plurality of caulking projections 714 are inserted into the plurality of caulking holes 726. The plurality of (four in this case) caulking holes 726 are arranged to surround the first fixing hole 85 at the first portion 721.

  Here, as shown in FIG. 11, the reinforcing member 72 further includes a protection protrusion 725 which protrudes from the surface of the second portion 722 facing the front surface 711 of the resin frame 71. The protective projection 725 is inserted into a protective recess 713 formed on the resin frame 71. The protective protrusions 725 are located between the centers of the vertical frames 83 in the vertical direction and the caulking holes 724 in the vertical direction. That is, the protective projection 725 is located inside the vertical frame 83 in the vertical direction with respect to the caulking hole 724 (the center side in the vertical direction of the vertical frame 83). As a result, when the vertical frame 83 is elastically deformed in the left-right direction, shear stress acts on the protective protrusion 725, and shear stress acting on the caulking protrusion 712 can be reduced.

  Further, in the present embodiment, on the front surface of the reinforcing member 72, on the opposite side to the opening window 81 in the vertical direction with respect to the first fixing hole 85, along the longitudinal direction of the oblong first fixing hole 85. Ribs 727 are formed. Accordingly, the periphery of the first fixing hole 85 which is particularly easy to exert a force by tightening the fixing screw in the reinforcing member 72 is reinforced by the rib 727, and the deformation of the mounting frame 8 is suppressed. Further, in the reinforcing member 72, a portion closer to the opening window 81 than the first fixing hole 85 in the vertical direction has a shape recessed rearward relative to a portion opposite to the opening window 81 from the first fixing hole 85. It is formed. Thus, 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 opposite to the opening window 81 with respect to the first fixing hole 85. The moment acting on can be kept small.

  Next, the frame side mounting portion 6 in 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 attachment portions 6 have a common configuration, the following description will be given by focusing on one frame side attachment portion 6 unless otherwise noted, and the other frame side attachment portions 6 The description thereof will be omitted as it has the same configuration. Here, when the mounting frame 8 is viewed from the front, attention is focused on the frame side mounting portion 6 positioned at the upper right (the portion shown by “A2” in FIG. 12A) among the four corners.

  The frame side attachment part 6 has the 1st control part 61 and the 2nd control part 62, as shown in Drawing 12B. The first restricting portion 61 has a rear surface 611 facing rearward as a contact surface with the first attachment portion 57 of the device-side attachment portion 102 of the wiring device 1. The second restricting portion 62 has a front surface 621 facing forward as a contact surface with the second attachment portion 58 in the device-side attachment portion 102 of the wiring device 1. The rear surface 611 of the first restricting portion 61 is in contact with the wiring device 1 and the front surface 621 of the second restricting portion 62 is in contact with the wiring device 1 in each of the pair of frame side attachment portions 6. The movement of the wiring device 1 in the front-rear direction is restricted. The first restricting portion 61 and the second restricting portion 62 are arranged at mutually different positions in the vertical direction.

  In the present embodiment, as shown in FIG. 12B, the first restricting portion 61 has a pair of first restricting pieces 610 separated in the vertical direction. The second attachment portion 58 includes a pair of second restriction pieces 620 separated in the vertical direction. The pair of first restriction pieces 610 is provided at a position corresponding to the pair of first attachment pieces 570 of the assembly frame 5. The pair of second restriction pieces 620 is provided at a position corresponding to the pair of second attachment pieces 580 of the assembly frame 5. Therefore, the first restricting portion 61 and the second restricting portion 62 are disposed at mutually different positions in the vertical direction so that the pair of second restricting pieces 620 are positioned inside the pair of first restricting pieces 610 in the vertical direction. It is done.

  The first restricting portion 61 is formed of a protrusion which protrudes toward the inside of the opening window 81 from each of the pair of inner side surfaces 831 (see FIG. 8A) facing the opening window 81 in the pair of vertical frames 83. Here, the protrusions are configured in pairs so as to correspond to the pair of first restriction pieces 610, and as shown in FIG. 12A, three pairs (six pairs) of protrusions are provided for each of the pair of vertical frames 83. ) Are formed one by one. The second first regulation piece 610 and the third first regulation piece 610 are integrated, and the fourth first regulation piece 610 and the fifth first regulation piece 610 are integrated. And are integrated.

  The second restricting portion 62 is formed by a rear wall of a restricting recess 832 formed on each of the pair of inner side surfaces 831 facing the opening window 81 in the pair of vertical frames 83. The restriction recess 832 is a recess opened to the front and the opening window 81 side. That is, the front surface 621 of the second restricting portion 62 is a bottom surface facing the front of the restricting recess 832. Here, the restriction recess 832 is configured in pairs so as to correspond to the pair of second restriction pieces 620, and is formed in three sets (six) for each of the pair of vertical frames 83. There is.

  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 opened to the front and the opening window 81 side. Here, three release recesses 835 are formed on the right vertical frame 83 so as to be located between the pair of restricting recesses 832. The release recess 835 is used to bend (elastically deform) the right vertical frame 83 to the right by inserting the tip of a jig such as a driver when removing the wiring device 1 from the mounting frame 8.

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

  Furthermore, the frame side attachment portion 6 further includes a dowel 612 (see FIG. 9) which protrudes from at least one of the rear surface 611 of the first restricting portion 61 and the front surface 621 of the second restricting portion 62. In the present embodiment, the dowels 612 are provided on the rear surface 611 of the first restricting portion 61. Although the details will be described later, in the state where the wiring device 1 is attached to the frame main body 80, the wiring device 1 is crushed and the dowel 612 is plastically deformed.

  Further, the frame side attachment portion 6 further includes a reinforcing rib 613 that protrudes rearward from the rear surface 611 of the first restricting portion 61. In the present embodiment, the reinforcing rib 613 is provided between the second first restricting piece 610 and the third first restricting piece 610 from the top, and the first first restricting pieces 610 and 5 from the top. It is formed only between the first first restriction piece 610. Although described later in detail, when the wiring device 1 is attached to the frame main body 80, the rear surface of the reinforcing rib 613 facing rearward does not contact the wiring device 1.

(2.4) Mounting structure of wiring fixture to mounting frame Next, a mounting structure for mounting the wiring fixture 1 on the mounting frame 8 (the fixture side mounting portion 102 and the frame side mounting portion 6) will be described with reference to FIGS. This will be described in more detail with reference to FIG. The following description will focus on one mounting structure (the instrument side mounting portion 102 and the frame side mounting portion 6) unless otherwise noted, and the description of the other mounting structures will be omitted as they have the same configuration. Here, pay attention to the mounting structure (the tool side mounting portion 102 and the frame side mounting portion 6) located at the upper right (the portion shown by “A3” in FIG. 13) of the four corners when the wiring device 1 is viewed from the front. I assume. Therefore, for example, with regard to the attachment structure positioned at the upper left of the four corners when the wiring apparatus 1 is viewed from the front, the left and right are reversed from the following description.

  As shown in FIGS. 13 and 14, the wiring fixture 1 is attached to the mounting frame 8 with at least the cover 3 inserted into the opening window 81 of the mounting frame 8. Here, when the wiring device 1 is attached to the mounting frame 8, the wiring device 1 is attached from the rear of the mounting frame 8 so as to be inserted into the opening window 81. At this time, the operator first fits the second mounting portion 58 as a mounting claw provided on the assembly frame 5 on the left side 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 operator is provided on the right assembly frame 5 of the wiring fixture 1 while bending the right vertical frame 83 of the mounting frame 8 to the right by pushing the right end portion of the wiring fixture 1 from behind. The second mounting portion 58 as a mounting claw is inserted into the restriction 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 coupled to each other within the dimension 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 main body 80 is in contact with 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 (the instrument side mounting portion 102 and the frame side mounting portion 6) in the front and back direction, and the size of the mounting structure in the front and back 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 apparatus 1 in a state of being attached to the mounting frame 8 as viewed from below, and the area to which hatching (dot hatching) is applied represents the cover 3. In FIG. 15, the construction surface 800 is indicated by an imaginary line (two-dot chain line).

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

  In a state in which 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 instrument side attachment portion 102 are the first restriction in the frame side attachment portion 6. By contacting the portion 61 and the second restricting portion 62, the wiring device 1 is fixed. That is, in the instrument side attachment portion 102, the front surface 571 of the first attachment portion 57 contacts the attachment frame 8 from the rear, and the rear surface 581 of the second attachment portion 58 contacts the attachment frame 8 from the front. The movement of the body 4 in the front-rear direction with respect to 8 is restricted. In other words, the frame side attachment portion 6 is a frame by the rear surface 611 of the first restricting portion 61 coming into contact with the wiring apparatus 1 from the front and the front surface 621 of the second restricting part 62 coming into contact with the wiring apparatus 1 from the rear 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 attachment portion 102 is a front surface 571 (see FIG. 5A) of the first attachment portion 57 (a pair of first attachment pieces 570). (1) Contact the rear surface 611 (see FIG. 12B) of the first restricting portion 61 (a pair of first restricting pieces 610). Thereby, the forward movement of the wiring device 1 relative to the frame main body 80 is restricted. At this time, the dowels 612 formed on the rear surface 611 of the first restricting portion 61 are crushed and plastically deformed by the front surface 571 of the first attachment portion 57. Therefore, even if there is a slight dimensional error between the instrument side mounting portion 102 and the frame side mounting portion 6, the plastic deformation of the dowel 612 can absorb the influence of the dimensional error, and the wiring fixture 1 for the mounting frame 8 The rattling is suppressed. Further, in this state, the front surface 571 of the first attachment 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 appliance-side attachment portion 102 restricts the rear surface 581 (see FIG. 5A) of the second attachment portion 58 (a pair of second attachment pieces 580) to a second restriction in the frame-side attachment portion 6. The front surface 621 (see FIG. 12B) of the portion 62 (a pair of second restriction pieces 620) is brought into contact. As a result, the wiring device 1 is restricted from moving backward relative to the frame main body 80. Therefore, movement of the wiring device 1 in the front-rear direction with respect to the frame main body 80 is restricted.

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

  By the way, in the wiring fixture 1 attached to the construction surface 800 (refer to FIG. 1) using the mounting frame 8 as described above, wiring is performed when the wiring fixture 1 is installed (at the time of attachment) or when the wiring fixture 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 in a state in which the wiring device 1 is attached is attached to the construction surface 800, the wiring or the like connected to the wiring device 1 is directed to push the wiring device 1 forward with respect to the wiring device 1. Force works. Also, when using the wiring apparatus 1, the wiring apparatus 1 is connected to the wiring apparatus 1 when so-called “sloppy removal” of removing the plug by holding the power cord or when a person's foot etc. is caught in the power supply cord. Force in the direction that pulls forward acts. Furthermore, when using the wiring device 1, when inserting the plug, a force acts on the wiring device 1 to push the wiring device 1 backward. Even when such a force acts, in the wiring device 1 according to the present embodiment, as described above, the movement of the wiring device 1 relative to the frame main body 80 in the front-rear direction is restricted. The cling is suppressed.

(3) Modifications The wiring device 1, the attachment frame 8, or the assembly frame 5 according to the first embodiment is only an example of the present invention, and the present invention is not limited to the first embodiment. Even if it is except, as long as it does not deviate from the technical idea concerning the present invention, various changes are possible according to design etc. Below, the modification of Embodiment 1 is enumerated.

(3.1) First Modified Example A wiring apparatus 1A according to a first modified example of the first embodiment is a wiring apparatus 1 according to the first embodiment in that a container 4A of unit dimensions is provided as shown in FIG. It is different from. That is, the wiring device 1A has the device main body 40A of the dimension which can be attached with respect to the attachment frame 8 to a maximum of three. In the wiring device 1A, the body 2A and the cover 3A are coupled by a pair of assembly frames 5. Only one set of insertion holes 311A is formed in the front surface 31A of the wiring device 1A. That is, the wiring device 1A is a single-opening type outlet. The wiring fixture 1A is attached to, for example, the center of the opening window 81 in the vertical direction.

(3.2) Second Modified Example The mounting frame 8A according to the second modified example of the first embodiment is, as shown in FIG. It is different from Frame 8. That is, the attachment frame 8A can attach the container 4A of unit dimensions by any number in the range of one to two. The mounting frame 8A has two pairs of frame side mounting portions 6A arranged in the vertical direction. Similar 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 regulation portion 61 (a pair of first regulation pieces 610) and a second regulation portion 62 (a pair of first regulation pieces 610). 2) having a restriction piece 620).

(3.3) Third Modification As shown in FIG. 20, the assembly frame 5A according to the third modification of the first embodiment is carried out in that the first attachment portion 57 (see FIG. 5A) is omitted. It differs 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) projecting to both sides in the vertical direction from both end surfaces in the vertical direction of the assembly frame 5, and the dimension in the vertical direction of the assembly frame 5 is reduced. be able to. The wiring fixture 1 using this assembly frame 5A is attached in place of the front surface 571 (see FIG. 5A) of the first attachment portion 57 so that the front surface of the first side portion 51 contacts the attachment frame 8 from the rear. It is attached to the frame 8. That is, when the wiring fixture 1 using the assembly frame 5A is attached, an attachment frame having a regulation portion at a position in contact with the front surface of the first side portion 51 is used instead of the first regulation portion 61 (see FIG. 16). .

(3.4) Fourth Modification In the wiring device 1B according to the fourth modification of the first embodiment, as shown in FIGS. 21A and 21B, the assembly frame 5B is in the front-rear direction with respect to the first protrusion 34B. The wiring device 1 is different from the wiring device 1 according to the first embodiment in that it further includes an auxiliary rib 532 that is in contact with the second protrusion 24 side (rear). That is, the assembly frame 5B has the auxiliary rib 532 at a position facing the first side 51 at a constant 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 is 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 to the assembly frame 5. The pair of auxiliary ribs 532 provided in each of the assembly holes 54 protrudes in a direction approaching each other in the vertical direction from the portion on the first side 51 side of the step portion 534 (see FIG. 5B) of the connection side 53 .

  Further, in the wiring device 1B according to the fourth modified example, the first protrusion 34B has a pair of protruding pieces 342 that project from the rear surface 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 surface of the pair of first protrusions 341 is not a flat surface, and is formed in a shape in which both end portions in the vertical direction are recessed.

  In the state where the assembly frame 5B is attached to the housing 4, as shown in FIG. 21B, the pair of auxiliary ribs 532 is from the second protrusion 24 side (rear) in the front-rear direction with respect to the pair of first protrusions 341. Contact. That is, the assembly frame 5 </ b> B is attached to the container 4 in a state in which the pair of first protrusions 341 is 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 by the pair of auxiliary ribs 532 in the vertical direction.

  According to the configuration of the wiring device 1B according to the fourth modification, since the first protrusion 34B is supported by the auxiliary rib 532 from the second protrusion 24 side (rear) in the front-rear direction, the first protrusion 34B The force applied from the opposite side (front) to the second protrusion 24 in the front-rear direction can be received by the auxiliary rib 532. Therefore, for example, at the time of installation (attachment) of the wiring device 1 or at the time of use of the wiring device 1, even if a large force in the direction to push (or pull) the wiring device 1 is applied, The first projection 34B can be protected to suppress the breakage of the first projection 34B.

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

(3.5) Other Modifications Hereinafter, modifications other than the first to fourth modifications of the first embodiment will be listed.

  The wiring apparatus 1 is not limited to indoor use, but may be an outdoor apparatus used outside the building. Further, the wiring fixture 1 is not limited to the one with a ground electrode, but may be without a ground electrode, and may be, for example, an AC 100 V or a DC outlet. Furthermore, the wiring device 1 is not limited to outlets compatible with A-type and C-type plugs, for example, outlets that can connect only A-type plugs or plugs such as B-type, BF-type, C-type or O-type It may be The wiring device 1 is not limited to the two-opening type outlet, and may be, for example, a one-opening type or a three-opening type outlet. Furthermore, the wiring device 1 is not limited to the outlet, and may be, for example, a switch, a human sensor or a timer. Furthermore, the wiring device 1 may be a combination of two or more functions among an outlet, a switch, a human sensor, a timer, and the like, for example, an outlet with a human sensor. Moreover, the terminal part of the wiring fixture 1 may not be a quick connection terminal, and may be, for example, a screw type terminal.

  The wiring apparatus 1 is not limited to a configuration (embedded installation type) installed with the rear portion embedded in the wall, and may be a configuration (exposed installation type) installed on the wall with the whole exposed. Good. Further, the mounting frame 8 is not limited to the configuration fixed to the embedded box, and may be configured to be mounted on the work surface 800 using, for example, a clamp.

  In addition, in the assembly frame 5, the first side 51 and the second side 52 may be arranged to be offset 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 The position of 52 may partially overlap. In this case, a part of the second side 52 is positioned in the projection plane along the front-rear direction of the first side 51.

  The hook 551 provided at the tip of the leg 55 may be hooked on at least one of the body 2 and the cover 3. For example, only the body 2 or only the cover 3 may be hooked. .

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

  Further, the assembly frame 5 is not limited to being separate from 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 an assembly frame 5 integrated with the mounting frame 8.

  In addition, the dowel 612 which is plastically deformed when the wiring device 1 is attached to the mounting frame 8 may be protruded from at least one of the rear surface 611 of the first restricting portion 61 and the front surface 621 of the second restricting portion 62. It may be projected from the front surface 621 of the regulating portion 62. In this case, the dowels 612 are crushed and plastically deformed by the rear surface 581 of the second mounting portion 58.

  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 attachment portion 58 is flush with (the same plane as) the front surface 571 of the first attachment portion 57 with the rear surface 581 of the second attachment portion 58. To a position where it is lowered backward. That is, in the wiring device 1 according to the first embodiment, the front surface 571 of the first attachment portion 57 is located slightly (for example, 0.5 mm) forward of the rear surface 581 of the second attachment portion 58. It may be set flush with 581. Therefore, according to this configuration, the amount of forward protrusion of the second attachment portion 58 from the front surface 571 of the first attachment portion 57 can be suppressed to a relatively small amount, and the pair of instrument side attachment portions 102 in the first direction can be thinned. Can be Similarly, in the mounting 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 may not be at the same position in the first direction, and if both can be regarded as substantially flush, the mounting structure Both securing of strength and thinning of the side mounting portion 102 and the frame side mounting portion 6 can be achieved. For example, the front surface 571 of the first mounting portion 57 may be offset from the rear surface 581 of the second mounting portion 58 in the first direction within a range of 0 mm or more and less than 3 mm.

(4) Summary As described above, the wiring device 1 according to the first aspect includes the container 4 and the pair of device side attachment parts 102. The body 4 is attached to the mounting frame 8 having the opening window 81 penetrating in the first direction (front-rear direction) in a state of being inserted into the opening window 81. The pair of instrument side attachment parts 102 are provided on both sides in the second direction (left and right direction) orthogonal to the first direction in the container 4. Each of the pair of instrument side mounting portions 102 has a first mounting portion 57 having a front surface 571 facing forward in one of the first directions, and a second rear surface 581 facing rearward in the other of the first direction. And a mounting portion 58. The front surface 571 of the first mounting portion 57 contacts the mounting frame 8 and the rear surface 581 of the second mounting portion 58 contacts the mounting frame 8 in each of the pair of instrument side mounting portions 102. The movement of the body 4 in the first direction is restricted. The first attachment portion 57 and the second attachment portion 58 are disposed at different positions in a third direction (vertical direction) orthogonal to both the first direction and the second direction.

  According to this configuration, the first mounting portion 57 in contact with the mounting frame 8 at the front surface 571 and the second mounting portion 58 in contact with the mounting frame 8 at the rear surface 581 are at different positions in the third direction. It is arranged. Therefore, the dimensions of the mounting structure (the instrument side mounting portion 102 and the frame side mounting portion 6) in the first direction can be reduced. For example, in the case where the rear surface 581 of the second mounting portion 58 contacts the mounting frame 8 from the front and the front surface 582 of the second mounting portion 58 contacts the mounting frame 8 from the rear, the second mounting portion in the mounting frame 8 Both forward and aft of 58 require structures for restricting the movement of the wiring device 1. According to the first aspect in which the mounting frame 8 is in contact with the mounting frame 8 by the first mounting portion 57 and the second mounting portion 58 which are arranged at mutually different positions in the third direction, as compared with this case. The dimensions of the mounting structure (the instrument side mounting portion 102 and the frame side mounting portion 6) can be reduced. If the dimensions of the mounting structure (the fixture-side mounting portion 102 and the frame-side mounting portion 6) in the first direction can be reduced, this leads to thinning of the mounting frame 8, and the amount of protrusion of the mounting frame 8 from the construction surface 800 is reduced. Be As a result, the amount of protrusion of the wiring device 1 mounted on the mounting frame 8 from the installation surface 800 can also be reduced.

  In the wiring device 1 according to the second aspect, in the first aspect, the front surface 571 of the first attachment portion 57 is preferably positioned rearward of the front surface 582 facing the front of the second attachment portion 58. According to this configuration, the front surface 571 of the first mounting portion 57 in contact with the mounting frame 8 from the rear and the rear surface 581 of the second mounting portion 58 in contact with the mounting frame 8 from the front will be close in the first direction. As a result, it is possible to reduce the thickness of the pair of instrument side attachment portions 102 in the first direction. However, this configuration is not an essential configuration for the wiring device 1, and the front surface 571 of the first attachment portion 57 may be located forward of the front surface 582 of the second attachment portion 58.

  In the wiring device 1 according to the third aspect, in the second aspect, the front surface 571 of the first attachment portion 57 is preferably at the same position as the rear surface 581 of the second attachment portion 58 in the first direction. According to this configuration, the amount of forward protrusion of the second attachment portion 58 from the front surface 571 of the first attachment portion 57 can be suppressed to a relatively small amount, and the pair of instrument side attachment portions 102 in the first direction can be thinned. be able to. However, this configuration is not an essential configuration for the wiring device 1, and the front surface 571 of the first mounting portion 57 and the rear surface 581 of the second mounting portion 58 may be at mutually different positions in the first direction.

  In the wiring device 1 according to the fourth aspect, in the first to third aspects, the second attachment portion 58 protrudes from each of the both end faces 22 (or both end faces 32) in the second direction of the housing 4 It is preferable to do. According to this configuration, the protruding second attachment portion 58 can be realized without increasing the dimension of the wiring device 1 in the third direction. However, this configuration is not an essential configuration for the wiring device 1, and for example, the second attachment portion 58 may be configured as a recess.

  In the wiring device 1 according to the fifth aspect, in the fourth aspect, the front surface 582 facing the front of the second attachment portion 58 is opposite to the body 4 than the end edge on the body 4 side in the second direction. Preferably, the side edge is an inclined surface inclined so as to be located rearward. According to this configuration, the body 4 is pushed into the opening window 81 from behind with respect to the mounting frame 8 to bend the mounting frame 8 by the front surface 582 of the second mounting portion 58 which is an inclined surface. 4 can be attached to the mounting frame 8. However, this configuration is not an essential configuration for the wiring device 1, and the front surface 582 of the second attachment portion 58 may not be an inclined surface.

  In the wiring device 1 according to the sixth aspect, in the fourth or fifth aspect, the second attachment portion 58 preferably has a pair of second attachment pieces 580 separated in the third direction. According to this configuration, the backward movement of the container 4 with respect to the mounting frame 8 is restricted by the at least one pair of second mounting pieces 580, compared to the case where there is one second mounting piece 580. The container 4 can be firmly attached to the mounting frame 8. If a portion of the mounting frame 8 (for example, both walls in the vertical direction of the release recess 835 shown in FIG. 16) is sandwiched between the pair of second mounting pieces 580, the mounting frame 8 in the third direction It is possible to regulate the movement of the body 4 with respect to However, this configuration is not an essential configuration for the wiring device 1, and the second attachment portion 58 may not have the pair of second attachment pieces 580.

  The attachment frame 8 according to the seventh aspect is provided with a frame main body 80 to which the wiring device 1 is attached by forming the opening window 81 penetrating in the first direction and the wiring device 1 being inserted into the opening window 81 . The frame main body 80 has a pair of frame side attachment portions 6 provided on both sides of the opening window 81 in the second direction orthogonal to the first direction. Each of the pair of frame side attachment portions 6 has a second restricting portion 62 having a front surface 621 facing frontward in one of the first direction and a rear surface 611 facing back in the other of the first direction. And a control unit 61. The rear surface 611 of the first restricting portion 61 is in contact with the wiring device 1 and the front surface 621 of the second restricting portion 62 is in contact with the wiring device 1 in each of the pair of frame side attachment portions 6. The movement of the wiring device 1 in the first direction is restricted. The first restricting portion 61 and the second restricting portion 62 are disposed at different positions in a third direction orthogonal to both the first direction and the second direction.

It is arranged. Therefore, the dimensions of the mounting structure (the instrument side mounting portion 102 and the frame side mounting portion 6) in the first direction can be reduced. For example, in the case where the front surface 621 of the second restricting portion 62 contacts the wiring device 1 from behind and the rear surface 622 of the second restricting portion 62 contacts the wiring device 1 from the front, the second restricting portion in the wiring device 1 Both forward and aft of 62 require structures to regulate movement of the wiring fixture 1. According to the seventh aspect in which the first restricting portion 61 and the second restricting portion 62 arranged at mutually different positions in the third direction are in contact with the wiring apparatus 1 as compared to this case, in the first direction The dimensions of the mounting structure (the instrument side mounting portion 102 and the frame side mounting portion 6) can be reduced. If the dimensions of the mounting structure (the fixture-side mounting portion 102 and the frame-side mounting portion 6) in the first direction can be reduced, this leads to thinning of the mounting frame 8 and the amount of protrusion of the mounting frame 8 from the construction surface 800 is reduced Be As a result, the amount of protrusion of the wiring device 1 mounted on the mounting frame 8 from the installation surface 800 can also be reduced.

  In the attachment frame 8 according to the eighth aspect, in the seventh aspect, the rear surface 611 of the first restricting portion 61 is preferably positioned forward of the rear surface 622 facing the rear of the second restricting portion 62. According to this configuration, the rear surface 611 of the first restricting portion 61 in contact with the wiring device 1 from the front and the front surface 621 of the second restricting portion 62 in contact with the wiring device 1 from the rear can be brought closer in the first direction. As a result, it is possible to make the frame side mounting portion 6 thinner in the first direction. However, this configuration is not an essential component of the mounting frame 8, and the rear surface 611 of the first restricting portion 61 may be located forward of the rear surface 622 of the second restricting portion 62.

  In the mounting frame 8 according to the ninth aspect, in the eighth aspect, the rear surface 611 of the first restricting portion 61 is preferably at the same position as the front surface 621 of the second restricting portion 62 in the first direction. According to this configuration, the amount of forward projection of the first restricting portion 61 from the front surface 621 of the second restricting portion 62 can be suppressed to a relatively small amount, and thinning of the pair of frame side attachment portions 6 in the first direction can be achieved. be able to. However, this configuration is not an essential component of the mounting frame 8, and the rear surface 611 of the first restricting portion 61 and the front surface 621 of the second restricting portion 62 may be at mutually different positions in the first direction.

  In the attachment frame 8 according to the tenth aspect, in any one of the seventh to ninth aspects, the frame main body 80 preferably has a pair of vertical frames 83 facing each other through the opening window 81 in the second direction. In this case, the second restricting portion 62 preferably comprises the rear wall of the restricting recess 832 formed in each of the pair of inner side surfaces 831 facing the opening window 81 in the pair of vertical frames 83. According to this configuration, the second restricting portion 62 can be realized without increasing the dimension of the wiring device 1 in the third direction. However, this configuration is not an essential configuration of the mounting frame 8, and for example, the second regulating portion 62 may be configured by a protrusion.

  In the mounting frame 8 according to the eleventh aspect, in the tenth aspect, the second restricting portion 62 preferably includes a pair of second restricting pieces 620 separated in the third direction. According to this configuration, the backward movement of the wiring device 1 with respect to the mounting frame 8 is restricted by the at least one pair of second restriction pieces 620, so compared to the case where there is one second restriction piece 620.
