Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a wiring equipment mounting device used for mounting wiring equipment such as switches and outlets to indoor walls, etc., and in particular, to a wiring equipment mounting device used for mounting wiring equipment such as a switch or an outlet on an indoor wall. The present invention relates to a wiring equipment mounting device suitable for

[Prior Art] Generally, as a wiring device, there is a switch 1 as shown in FIG. 6, for example.

This switch 1 has a switch body 3 having a boss portion 2, and engagement plates 5 and 6 attached to the switch body 3 to be engaged with a mounting frame 4. Each engagement plate 5 and 6 has two Convex portions 5a and 6a are formed respectively. An example of a plate mounting frame for mounting the switch 1 having such a structure is shown in FIG. 5.

This plate mounting frame 4 is formed with only one through hole 7 for mounting the three switches 1, and the peripheral walls on both sides thereof are provided with through holes 7 for locking the three switches 1. A locking means consisting of a set of a highly rigid locking portion 8 and a flexible locking piece 9 is provided.

When the switch 1 is mounted on the plate mounting frame 4, the protrusion 6a provided on one of the engagement plates 6 of the switch 1 is engaged with the engagement gap 10a on the engagement portion 8, and the protrusion 6a provided on the engagement plate 6 of the switch 1 is engaged with the engagement gap 10a on the engagement portion 8. While warping the locking piece 9 with the projection 5a provided on the locking piece 5, the projection 5a is engaged with the locking gap 10b on the locking piece 9 and installed.

In addition, 11 in the figure is an external plate that covers the outside of the plate attachment frame 4.

[Problems to be Solved by the Invention] However, in such a conventional plate mounting frame, when a large number of switches 1 etc. are mounted, the through holes 7 must be made longer or provided in multiple rows. However, when multiple rows of through holes 7 are provided, the dimensions between adjacent switches 1 and 1 are determined by Japanese Industrial Standards (JIS), so It is not possible to increase the width of the boundary formed in the area. Therefore, locking portions 8 are provided on the peripheral walls on both sides of each through hole 7, corresponding to each through hole 7.
Also, there was a problem that the locking pieces 9 could not be provided separately and independently.

Further, even if the locking portion and the locking piece at the boundary portion are provided with extremely thin walls, there is a problem that the locking strength of the wiring device becomes too weak to be practical.

The present invention has been made in view of the above conventional problems, and the locking portion and the locking piece located at the boundary between the through holes arranged in parallel on a single plate mounting frame are mutually separated. It is an object of the present invention to provide a wiring equipment mounting device that allows a large number of wiring equipment to be mounted in multiple rows according to the standard by integrally configuring the lower end portions of the wiring equipment.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides through holes in a single mounting frame, through which the boss portions of a single or a plurality of wiring devices pass through, A locking portion for locking a convex portion or a recess provided in the wiring device and a flexible locking piece are provided on the peripheral walls on both sides of each through-hole, and a locking piece is provided at a boundary portion formed between adjacent through-holes. The locking portion and the locking piece are characterized in that their lower ends are continuous and formed into a substantially U-shape.

[Function] Accordingly, in the present invention, the locking portion and the locking piece provided at the boundary portion for locking the wiring device are formed into a substantially U-shape with their lower ends continuous to form an integral structure. By doing so, compared to the case where independent locking parts and locking pieces are provided, the formation area can be made as small as possible, and therefore the width of the boundary part can be set to a predetermined value that meets the standard. can be formed into

[Example] Next, an example of the present invention will be described with reference to the drawings.

Inside the single plate mounting frame 12,
Two through holes 14 are provided in parallel for mounting a switch 1, which is a specific example of a wiring device as shown in FIG. There is.

One through hole 14 is formed vertically so that three switches 1 can be attached thereto, and three flexible locking pieces are provided on the right peripheral wall of the through hole 14 located on the right side in FIG. 16, and three relatively rigid locking portions 17 are provided on the left peripheral wall of the through hole 14, which is also located on the left side.
Above each locking piece 16 and each locking part 17, locking gaps 18 and 19 are provided, into which the pair of protrusions 5a and 6a provided on the engagement plates 5 and 6 of the switch 1 described above are inserted. They are set respectively.

Further, the boundary portion 15 has three locking portions 20 corresponding to the three locking pieces 16, and three locking pieces 21 corresponding to the three locking portions 17.
are set up respectively. These three locking portions 20 and locking pieces 21 are formed at three locations separated by two ribs 23 that partition a long hole 22 provided in the boundary portion 15. Each locking portion 20 and each locking piece 2
Above the switch 1, the engagement plate 5 of the switch 1 mentioned above,
Locking gaps 24 and 25 are respectively set into which the pair of protrusions 5a and 6a provided at 6 are inserted.

The locking portion 20 and the locking piece 21 are formed so that their lower ends are continuous and form a substantially U-shape. The locking part 20 formed on one side is directly connected to the rib 23 to increase rigidity, while the locking piece 21 formed on the other side is connected to the relatively thick base 23.
1a, a slightly thin tip portion 21b that stands narrowly above the base 21a, and a notch 21c provided between adjacent locking pieces 21 with the rib 23 in between. The presence of the locking piece 2 lowers the rigidity and imparts elasticity to the locking piece 2

Therefore, similar protrusions are formed on a locking piece (not shown) that pairs with the locking part 30 and a locking part (not shown) that pairs with the locking piece 31. The other configurations are the same as those of the embodiment described above, and similar effects can be obtained by configuring in this way.

Note that in the above embodiment, the through hole 14 is
Although an example has been described in which they are arranged in parallel at locations, the present invention is not limited to this, and it goes without saying that a structure in which they are arranged in parallel at three or more locations is also possible. Further, in the above embodiment, the rigidity of the locking portion 20 is set high, but similarly to the locking piece 21, the rigidity may be lowered to provide flexibility. Further, the shapes of the locking portion 20 and the locking piece 21 are not limited to those illustrated, and various shapes can be adopted depending on the shape of the convex portion or recess provided in the wiring device.

In addition, although the wiring device mounting device of the above embodiment is illustrated as a plate mounting frame in which the plate edge frame and the wiring device mounting means are integrally provided, the insulating mounting frame is formed separately from the plate edge frame. It is also possible to adopt the form of

[Effects of the Invention] As explained above, according to the present invention, a locking portion and a locking portion formed in a substantially U-shape by connecting the lower ends of each other are provided at the boundary portion provided between adjacent through holes. Because of the structure in which a stopper is provided, when a large number of wiring devices are arranged and installed in multiple cases, the stopper and stopper can be attached to the narrow boundary that can be formed between adjacent through holes. In addition, even if the locking portion and the locking piece of the boundary portion are provided with extremely thin walls, the locking strength of the wiring device can be configured to be sufficient to withstand actual use. . Therefore, it is possible to provide a wiring equipment mounting device that can smoothly mount wiring equipment in a plurality of rows at standard dimensional positions.
