  Hereinafter, as shown in FIGS. 1 and 2, a wiring device is shown in which a wiring device 2 is attached to a wiring device plate 1 that is attached to a construction surface with a construction surface (not shown) side such as a wall as a rear surface.

  The wiring device plate 1 exemplified in the present embodiment has a rectangular front surface, and a mounting hole 12 into which the wiring device 2 is inserted and attached from the front is provided in the front-rear direction (thickness direction).

  Insertion ribs 18 project from the rear surface of the wiring instrument plate 1 so as to surround the attachment holes 12, and screw attachments through which attachment screws for fixing to the construction surface are inserted are inserted into the periphery of the attachment holes 12. A plurality of holes 11 are provided in the front-rear direction. After inserting the insertion rib 18 into a construction hole (not shown) provided on the construction surface, the wiring device plate 1 is fixed to the construction surface with a mounting screw.

  That is, the attachment hole 12 is located in front of the construction hole, and the wiring device 2 is attached to the attachment hole 12 such that the rear part is embedded in the construction surface.

  A decorative plate P having substantially the same shape as the front surface of the wiring device plate 1 is attached to the front surface of the wiring device plate 1 to which the wiring device 2 is attached. The decorative plate P includes a window 42 through which the wiring device 2 is exposed to the front side. The decorative plate P is attached to the wiring device plate 1 with a plurality of engaging holes 17 formed on the front surface of the wiring device plate 1 and a plurality of engaging claws 41 formed on the rear surface of the decorative plate P. It is performed by engaging each.

  The size of the wiring device 2 that can be mounted in the mounting hole 12 by arranging a plurality (eight in the illustrated example) of wiring devices 2 along the longitudinal direction of the wiring device plate 1 is set as a unit dimension. The shape of the instrument 2 is determined based on the unit dimensions. For example, the wiring device 2 is formed in a unit dimension or a size such as 2, 3, 1.5 times the unit dimension.

  The wiring device 2 is, for example, a switch or an outlet. However, it may be a device to which a telephone line or a television antenna line is connected. In the present embodiment, as the wiring device 2, a switch 2a formed with unit dimensions and an outlet 2b formed with twice the unit dimensions are illustrated. That is, eight switches 2a can be attached to the attachment holes 12, and four outlets 2b can be attached to the attachment holes 12.

  The wiring device 2 includes a container body 21 having a terminal portion to which a front surface is formed in a rectangular shape and a power line (not shown) is connected. In the switch 2 a, a switch operation unit 30 is provided on the front surface of the container body 21. In the outlet 2b, a plug insertion hole 31 into which a plug blade (not shown) of the plug is inserted is opened on the front surface of the container body 21.

  A terminal hole 22 into which a power supply line is inserted is opened on the rear surface of the container body 21. Further, a flange 23 projects from the peripheral surface of the front end portion of the container body 21. Below, the longitudinal direction of the plate 1 for wiring devices is demonstrated as a horizontal direction, and a transversal direction is demonstrated as a vertical direction.

  As shown in FIG. 3, mounting legs 26 are formed on the rear surfaces of both end portions of the flange 23 in the vertical direction. In the switch 2a, one piece (two in total) is formed at the center of each end of the flange 23, and two pieces (four in total) are formed in each end of the flange 23 in the outlet 2b.

  Positions of the four mounting legs 26 formed on the outlet 2b so that they are in the same position as the positions of the four mounting legs 26 when two switches 2a formed with unit dimensions are arranged close to each other in the vertical direction. Is decided.

  Each mounting leg 26 is formed so as to be along a set of peripheral surfaces 25 parallel to each other in the vertical direction among the four peripheral surfaces of the container body 21 and to have a gap between the peripheral surfaces 25. Furthermore, the attachment leg 26 has elasticity that makes the distance between the peripheral surface 25 variable. That is, the mounting leg 26 can be bent so as to approach the peripheral surface 25.

  A hooking claw 27 projects from the tip of each mounting leg 26 in a direction away from each other in the vertical direction.

  Further, flanges 28 are respectively provided on both end surfaces of the flange 23 facing each other in the vertical direction. The flange piece 28 includes a flange piece base portion 28a that protrudes from the end face of the flange 23, and a flange piece protrusion portion 28b that protrudes backward from the tip end portion of the flange piece base portion 28a. The collar piece 28 is formed on both sides of each mounting leg 26. That is, in the switch 2a, a total of four hooks 28 are formed, two on each end face, and in the outlet 2b, a total of eight hooks 28 are formed on each end face.

  As shown in FIG. 4A, in the switch 2a ′, two mounting legs 26 are formed on each side (that is, four mounting legs 26 are formed), and two mounting legs 26 aligned in the lateral direction are formed. It can also be set as the structure which forms the collar piece 28 in the middle.

  Further, as shown in FIG. 4B, in the outlet 2b ′, the hook piece 28 is formed only on one side of the mounting leg 26 (in the illustrated example, the side that is to be positioned between the two mounting legs 26). It can also be configured.

  On the other hand, in the wiring device plate 1, as shown in FIGS. 1 and 2, among the four inner peripheral surfaces of the mounting hole 12, the set of inner peripheral surfaces 13 facing each other in the vertical direction has a front-rear direction. A plurality of mounting grooves 14 are recessed along the line.

  The mounting groove 14 has an opening on the front surface of the wiring device plate 1, and the mounting groove 14 is exposed on the front surface. The width dimension (lateral length dimension) of the mounting groove 14 is substantially the same as the width dimension (lateral length dimension) of the mounting leg 26 so that the mounting groove 14 can be fitted to the mounting leg 26. It is formed.

A plurality of insertion holes 15 into which the flanges 28 are respectively inserted are opened on both sides of the front opening of the mounting groove 14. The front surface of the portion between the insertion hole 15 and the attachment hole 12 in the wiring instrument plate 1 is located behind the opening of the insertion hole 15 and forms a support base 19.
As shown in FIGS. 5 and 6, when the wiring device 2 is inserted into the mounting hole 12 from the front so that each mounting leg 26 enters the mounting groove 14, the hooking claw 27 is moved to the bottom surface of the mounting groove 14. 14 c contacts and bends, and the flange protrusions 28 b are inserted into the insertion holes 15, respectively, and the rear surface of the flange base 28 a comes into contact with the front surface of the support 19. Here, the distance between the mounting leg 26 and the peripheral surface 25 is formed to be larger than the protruding dimension of the catching claw 27, and the mounting leg 26 does not hit the peripheral surface 25.

  Further, the length in the front-rear direction is such that the hooking claw 27 is caught on the rear surface of the wiring device plate 1 (the rear surface along the mounting hole 12) when the rear surface of the flange base 28a comes into contact with the front surface of the support base 19. With dimensions, the mounting hole 12 is formed. That is, when the rear surface of the hook base 28 a comes into contact with the front surface of the support base 19, the front surface of the hooking claw 27 is locked to the rear surface of the wiring device plate 1. In the present embodiment, as described above, the rear surface of the wiring device plate 1 (the rear surface of the portion along the attachment hole 12) is a claw receiving portion that receives the hooking claw 27.

  As described above, the wiring device 2 is restricted from moving in the vertical direction and the horizontal direction by fitting the mounting legs 26 into the mounting grooves 14, the rear surface of the hook base 28 a abuts against the front surface of the support base 19, and the hook. Since the front surface of the claw 27 is locked to the rear surface of the wiring device plate 1, movement in the front-rear direction is restricted. That is, the wiring device 2 is fixed to the wiring device plate 1.

  In addition, as shown in FIG. 7, a pair of rib 15c along a front-back direction can be formed in a pair of wall surface which mutually opposes in the insertion hole 15 in the horizontal direction. The rib 15c is formed with a thickness dimension (width dimension in the vertical direction) that can be crushed in the protruding direction (lateral direction). Further, the ribs 15 are formed so that the protruding dimension increases toward the rear.

  On the other hand, the width dimension (lateral length dimension) of the flange piece 28 is smaller than the width dimension of the insertion hole 15 and larger than the dimension between the tips of the rear portions of the pair of ribs 15c. The convex portion 28 d crushes the rib 15 c when entering the insertion hole 15. Therefore, the gap in the lateral direction between the flange piece 28 and the insertion hole 15 is filled with the crushed rib 15c, and the rattling of the wiring device 2 in the lateral direction is prevented.

  Next, removal of the wiring device 2 will be described with reference to FIG. As described above, the mounting groove 14 has an opening on the front side and is exposed on the front side. When the tip of a tool A such as a flat-blade screwdriver is inserted into the mounting groove 14 from the front and moved as indicated by the arrow in the figure, the mounting leg 26 is bent toward the peripheral surface 25 side of the body 21, and the hooking claw 27 is used for wiring equipment. It comes off from the rear surface of the plate 1 and the engagement between the rear surface of the hooking claw 27 and the rear surface of the wiring device plate 1 is released. That is, the wiring device 2 is removed from the wiring device plate 1.

  Here, as shown in FIG. 5, the bottom surfaces 14 c of the two mounting grooves 14 formed on the two inner peripheral surfaces 13 and facing each other in the vertical direction are inclined surfaces that are inclined away from each other toward the front. It is formed. Therefore, the gap dimension d between the bottom surface 14c and the mounting leg 26 at the opening of the mounting groove 14 is determined according to the inclination angle of the bottom surface 14c.

  In the present embodiment, the gap dimension d can be increased up to the width dimension of the frame portion of the wiring instrument plate 1 (the length dimension between the edge of the mounting hole 12 and the outer edge of the wiring instrument plate 1 in the vertical direction). By increasing the width dimension of the frame portion, the gap dimension d can be made larger than the conventional configuration in which the notch groove for inserting the tool A into the mounting leg 26 is formed. As a result, as shown in FIG. It is easy to insert the tip of the tool A into the opening of the mounting groove 14. In addition, since the tip of the tool A is guided to the mounting leg 26 side by sliding on the bottom surface 14c, even if the opening of the mounting groove 14 is large, the work for removing the wiring device 2 is not hindered. The removal work of the instrument 2 is easy.

  In the above-described conventional configuration, when the depth dimension of the notch groove is increased, the thickness dimension of the mounting leg is reduced accordingly, and the mounting leg may be damaged by the tool A. However, in this embodiment, the mounting groove 14 is a wiring device. Since it is formed on the plate 1, the strength of the mounting leg 26 does not decrease even if the gap dimension d is increased. Moreover, the strength of the mounting groove 14 can be sufficiently ensured by increasing the thickness of the wiring device plate 1 around the mounting groove 14. As a result, the possibility of damage by the tool A can be reduced as compared with the conventional configuration.

  In the conventional configuration, since the notch groove is formed in the mounting leg, the width dimension of the notch groove is smaller than the width dimension of the mounting leg. However, in this embodiment, the width dimension of the mounting groove 14 (the length in the lateral direction). The dimension) is substantially the same as the width dimension of the mounting leg 26. That is, the width dimension of the mounting groove 14 is larger than that of the conventional configuration, and the tip of the tool A can be easily inserted into the mounting groove 14.

  By the way, as shown in FIG. 9, the mounting grooves 14 formed side by side in the inner peripheral surface 13 of the mounting hole 12 are mounting grooves formed at intervals of the lateral length of the switch 2 a. 14a and a mounting groove 14b formed between two adjacent mounting grooves 14a.

  In addition, a plurality of (three in the illustrated example) deformation preventing bars 16 that connect the two inner peripheral surfaces 13 are provided in the middle between two adjacent mounting grooves 14a. The deformation preventing bars 16 are formed at a dimensional interval twice as long as the lateral length of the switch 2a.

  Of the three deformation prevention bars 16 in the figure, the deformation prevention bars 16 are formed in the mounting grooves 14b formed between two adjacent mounting grooves 14a, like the central deformation prevention bars 16. Of the three deformation prevention bars 16 in the figure, like the deformation prevention bars 16 at both ends, a mounting groove 14b is formed between two adjacent mounting grooves 14a. It is also possible to form the deformation prevention bar 16 in a portion that is not present.

  As described above, each mounting groove 14 provided on each inner peripheral surface 13 is divided into three by the deformation preventing bars 16. When the switch 2a is attached so that the attachment leg 26 fits into the attachment groove 14 located at the end of the three attachment grooves 14 in each part of the attachment hole 12 partitioned by the deformation prevention bar 16, as described above. The deformation prevention bar 16 is formed in the middle of the two adjacent mounting grooves 14a, and the distance between the two adjacent mounting grooves 14a is substantially the same as the horizontal dimension of the switch 2a. Since the leg 26 is formed at the center in the lateral direction of the front end portion 22 of the body, the switch 2a (the switch 2a on the left side in the figure) approaches the deformation preventing bar 16.

  Further, when the switch 2a is attached so that the attachment leg 26 fits into the attachment groove 14 located in the middle of the three attachment grooves 14 in each part of the attachment hole 12 partitioned by the deformation preventing bar 16, the switch 2a (The switch 2a on the right side in the figure) is located in the middle of the two deformation preventing bars 16.

  As described above, in each part of the mounting hole 12 partitioned by the deformation prevention bar 16, the switch 2a is shifted to the mounting hole 12 by shifting in the horizontal direction every half of the length of the switch 2a in the horizontal direction. Can be attached.

  In addition, as shown in FIG. 11, it can also be set as the structure which does not provide the deformation | transformation prevention crosspiece 16 (refer FIG. 9). In that case, the mounting groove 14 is formed at a dimensional interval that is half the length of the switch 2a in the lateral direction. That is, as shown in FIG. 12, the wiring device 2 can be attached to the attachment hole 12 while being shifted in the horizontal direction at a distance that is half the length of the switch 2 a in the horizontal direction.

  By the way, the deformation preventing bar 16 connects the two inner peripheral surfaces 13 of the mounting hole 12, so the deformation preventing bar 16 allows the wiring device plate 1 to be extended so that the distance between the two inner peripheral surfaces 13 is increased. Deformation is prevented.

  Therefore, the wiring device plate 1 is not deformed, and the hooking claw 27 does not come off the rear surface of the wiring device plate 1 that is the claw receiving portion (the rear surface at the end portion along the attachment hole 12).

  As shown in FIG. 13, the deformation preventing bar 16 is located at a position behind the flange 23 that is the front end portion of the container body 21 and at a side of the narrow portion that is the rear end portion of the container body 21. To be formed. Therefore, when the wiring device 2 is attached to both sides of the deformation preventing beam 16 so as to be close to the deformation preventing beam 16, the deformation preventing beam 16 is hidden by the respective flanges 23 of the two wiring devices 2. As a result, the aesthetic appearance is not impaired by the deformation preventing bar 16.

  By the way, in this embodiment, as shown in FIG. 3, the two peripheral surfaces 25 of the container body 21 are formed to be inclined so as to approach each other toward the rear (downward in the drawing). Accordingly, the length dimension of the rear surface of the container body 21 in the vertical direction is smaller than the length dimension of the mounting hole 12 in the vertical direction, and when the wiring device 2 is inserted into the mounting hole 12 from the front, 21 b can be easily inserted into the mounting hole 12, and the wiring device 2 is guided to a fixed position (mounting position) by the sliding contact between the peripheral surface 25 and the inner peripheral surface 13 of the mounting hole 12. The operation of attaching the to the attachment hole 12 becomes easy.

  In addition, the plate 1 for wiring devices can also be attached to a construction surface by making a vertical direction into an up-down direction, and can be attached to a construction surface by making a horizontal direction into an up-down direction.
