The distance of 3 is a standardized unit-size embedded wiring device.
It is set equal to the mounting frame for three large squares that can be mounted up to three pieces. As a result, the mounting frame 61 can be attached to a ready-made embedding box for wiring equipment.

Further, plate screw holes 65 into which plate screws are screwed are formed above and below each of the mounting windows 61 of the mounting frame 60, so that the decorative plate 5 used when installing a standardized embedded wiring device is formed. (See FIG. 7) can be attached to the mounting frame 60. The decorative plate 5 is a mounting frame 6
It comprises a lower plate 5a fixed to 0 and an outer plate 5b coupled to the lower plate 5a. As described above, since the ready-made decorative plate used in the embedded wiring device can be attached to the mounting frame 60, not only the embedding box but also the decorative plate can be used. Therefore, it is possible to suppress an increase in the manufacturing cost of the members required for the construction.

A pair of hook holes 66 are also formed above and below each mounting window 61 in the mounting frame 60, and a peripheral portion of the mounting hole formed in a wall panel or the like is sandwiched between the mounting frame 60 and the mounting hole 60. With one end of the clip fitting inserted into the hook hole 66,
By tightening the attraction screw screwed into the clamp through the mounting hole 64, the end of the clamp is attached to the mounting frame 6.
It can be made to approach zero.

By the way, the center piece 69 of the mounting frame 60 is located at a position different from the first receiving portion 62 and the second receiving portion 63.
Bridges 71 are formed at two locations, the sides of which are cut out so as to be narrower than the other locations. A base 70 made of an insulating material is fitted to the bridge 71.
A holding groove 73 is formed on the front surface of the base 70 so as to extend across both the mounting windows 61, and a conductive piece 74 made of a conductive material is fixed in the holding groove 73. On the back of the base 70,
A pair of leg pieces 75 that are respectively fitted to the cutout portions on both sides of the bridge 71 are protruded. Bridge 7 to base 70
1, the left and right sides of the base 70 and the left and right sides of the center piece of the mounting frame 60 are substantially flush.

The bridge 71 described above is provided so as to correspond to the contact portion 3a of the lead plate 3 exposed from the case 1 in a state where the case 1 is attached to the mounting frame 60, and FIG.
As shown in FIG. 7, a part of the contact portion 3a is
3 is brought into contact with the conductive piece 74. Here, since the lead plate 3 is formed by a leaf spring and has elasticity in the front-rear direction (vertical direction in FIG. 12),
The contact portion 3a and the conductive piece 74 make reliable contact. Accordingly, when the case 1 is mounted in the two mounting windows 61 of the mounting frame 60, if the two bases 70 are mounted on the mounting frame 60, the lead plate 3 is electrically connected between the two cases 1. Will be connected. Since the lead plate 3 is connected to the signal line Ls via the connector 4 as described above, the signal line is sent and wired between the two cases 1. That is, if the connector 4 is connected to one of the two cases 1 and the signal line Ls is connected to the one case 1, the other case 1 is connected to the other case 1 via the lead plate 3 and the conductive piece 74. Therefore, even if two cases 1 are provided, only one connector 4 needs to be provided.

According to the above-described structure, the rear surface of the case 1 is located forward of the rear surface of the mounting frame 60. Therefore, when the mounting frame 60 is brought into contact with the construction surface and mounted, the case 1
It is not necessary to form a hole for inserting the rear part on the construction surface, and the construction work becomes easy. Moreover, if the connector 4 is connected to one case 1, the signal lines Ls can be sent and wired between the cases 1 via the conductive pieces 74 attached to the mounting frame 60. If only one is used, a plurality of cases 1 can be attached to the construction surface. Alternatively, the mounting frame 60 may be directly attached to the construction surface without using the embedding box 4, and in that case, a hole large enough to accommodate the connector 4 may be formed on the construction surface. In addition, the construction is further facilitated as compared with the case where the embedding box is used.

The body 10 has up and down dimensions and left and right dimensions of about three unit dimensions of standardized wiring equipment. Since it can be formed, a relatively large number of parts can be stored in the case 1. Also,
In the above embodiment, two cases 1 are attached to the attachment frame 60. However, the attachment frame 60 is formed so that only one case 1 is attached, or three or more cases 1 are attached. The mounting frame 60 may be formed so that it can be attached.
