In the wiring device mounting frame 1, the locking projections 14 are provided on the left wall frame 4 of FIG. 1 at positions corresponding to the two locking projections 14 on the left edge of the wiring device 11. A plurality of (four in the figure) locking holes 5 that can be inserted from the back side are arranged along the periphery of the front opening 3. The locking holes 5 , the locking claws 6 and the side walls 7 correspond to the locking portions in the claims, and as shown in FIGS. The gap formed by the side wall 7 and the back surface of the flat portion 2 is such that the distance between the locking claw 6 and the back surface is large enough to insert the locking protrusion 14 of the wiring device 11. In addition, the square hole formed in the plane portion 2 at the position of the locking hole 5 is provided for molding reasons so that the locking claw 6 can be formed.

On the other hand, on the right side wall frame 4 in FIG. 1, both edges 2 on the right end of the wiring device 11 are located at positions corresponding to the two locking projections 14 on the right end of the wiring device 11. Individual locking projection 1
In order to lock the lock 4, a lock piece 8 erected obliquely upward is integrally provided. The locking piece 8 is formed to have a width corresponding to the width of the mounting piece 13 of the wiring device 11, and further has a locking recess 8 a for locking with the locking projection 14 of the wiring device 11 as shown in FIG. 6. Displacement preventing portions 8b are provided on both sides of the engaging projections 14 to prevent the engagement projections 14 from coming off due to displacement. That is, the width of the locking concave portion 8a is set to a size such that even if the locking protrusion 14 is shifted in the left-right direction in FIG. Since the locking pieces 8 are inclined obliquely upward, the locking pieces 8 are elastically displaced by bending outwardly around the lower end when pressed by the locking projections 14 from below. The elongated holes formed in the flat portion 2 above the locking pieces 8 are also provided for molding reasons.

Here, of the four locking holes 5, two locking holes 5 a in the middle portion are formed to have a width dimension substantially equal to the width of the locking projection 14. On the other hand, the locking holes 5b at the upper and lower ends are formed wider by a predetermined dimension than the width of the locking projections 14 of the wiring device 11. That is, the width dimension of the locking holes 5b at the upper and lower ends is such that a two-piece wiring device 11a having two insertion ports 12 shown in FIG. 11a is extended inward by a length capable of locking the locking protrusions 14 on the upper and lower sides of the upper surface 11a.

The distance L between the two locking holes 5a and the locking pieces 8 in the middle part is equal to the distance between the locking projections 14 of the wiring device 11.

Here, in order to mount the wiring device 11, as shown in FIG. 7, from the back side of the wiring device mounting frame 1, first, the locking projection 14 on the left side of the wiring device 11 is inserted into the locking hole 5 from the horizontal direction. insert. Next, when the right locking projection 14 is brought into contact with the inclined surface of the locking piece 8 from below and pressed toward the flat portion 2, the locking piece 8 has its lower end as a base end. the tip in the axial deflection to the right, the locking projection 14 is the
Engaging pieces 8 exceeds tip resiliently returns to its original inclined state, as shown in FIG. 8, the locking projection 14 in front of the locking piece 8
It is locked between the front end and the rear surface of the flat portion 2.

After the wiring tool 11 is attached in this manner, the locking projection 14 locked on the locking piece 8 is prevented from coming off, and the wiring tool 11 tries to rotate around the left end portion by the slip prevention portion 8b. The displacement is also prevented, and it is prevented from coming off from the wiring device mounting frame 1. In order to remove the wiring device 11 once attached, the locking piece 8 is pressed outward to release the locking state of the locking projection 14, and then the left locking projection is removed from the left locking hole 5. The wiring device 11 is removed by removing 14.

Next, in order to attach only one wiring device 11 to the intermediate portion of the wiring device mounting frame 1, as shown in FIG. Since L is equal to the distance L1 between the locking projections 14 of the wiring device 11, the mounting can be easily performed by the same operation as in the case of mounting the two devices.

Here, a description will be given of the mounting of the two-piece integrated wiring tool 11a provided with two insertion ports 12 as shown in FIG. 4 using the wiring tool mounting frame 1. In this embodiment, as described above, the wiring device mounting frame 1
Only the width of the locking holes 5b at both ends of the locking projections 14 is larger than the width of the locking projections 14. This is because the spacing between the locking projections 14 of the wiring device 11 and the wiring device 11a is substantially common among manufacturers, and the two-piece wiring device 11 shown in FIG.

In the case where it is only necessary to change the number of wiring devices 11 to be mounted as appropriate, it is only necessary that the distance between the locking holes 5 and the locking pieces 8 be set to a predetermined size. Does not need to be particularly wide.

<Second Embodiment> Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment,
The wiring device mounting frame 1 can mount three wiring devices 11. In the drawing, the width of the locking holes 5 is substantially the same as the width of the locking projections 14 only at the two locking holes 5a at the upper and lower ends, and the four locking holes 5b provided therebetween are the same as those of the first embodiment. The width is increased similarly to the locking hole 5b of the example. The width of the locking recess 8 a, which is the locking portion formed by the slip prevention portion 8 b in the opposite locking piece 8, is set to two types corresponding to the locking hole 5. However, the locking piece 8
The width of the locking recess 8a is not particularly limited as long as the wiring device 11 can be prevented from being displaced in the rotating direction and coming off. In the wiring device mounting frame 1 of the second embodiment, as shown in FIG. 10, the distance between the locking holes 5 is adjusted so that two wiring devices 11 can be mounted in the intermediate portion. As described above, the width of the locking hole 5b is increased.

With such a configuration, in the second embodiment, one wiring device mounting frame 1 is used for three wiring devices 1.
1. Two wiring tools 11 can be attached to the middle part, and a two-piece wiring tool 11a in which two insertion ports 12 are integrally provided as shown in FIG. 4, and further as shown in FIG. It is also possible to attach a three-piece integrated wiring device 11b in which three different insertion ports 12 are integrally provided.

The wiring device mounting frame 1 of the first embodiment can mount a maximum of two wiring devices 11, and the wiring device mounting frame 1 of the second embodiment has a maximum of three wiring devices 11. Although the present invention can be mounted, the present invention is not limited to this when practicing the present invention. The present invention can be similarly applied to the wiring device mounting frame 1 on which four or more wiring devices 11 can be mounted. In addition, in the wiring device mounting frame 1 of each of the above-described embodiments, the wiring device 11 is mounted by the locking holes 5 and the locking pieces 8, but the wiring device is not limited to this mounting means. The wiring device mounting frame 1 of the present invention includes a dimmer, a wiring device for an outlet and a switch,
It goes without saying that the present invention can be similarly applied to the installation of a wiring device such as a ground.
