The base 5 is covered with a lid (not shown) while being electrically connected and arranged. The base 5 is attached and fixed to the opening provided in the wall material W by the attachment 6.
[0008]
The attachment 6 is formed to have a substantially L-shaped cross section . A first support shaft 9 is formed at one end and a second support shaft 10 is formed at the other end, and a bolt insertion hole 11 is formed. The adjustment piece 12 and the insertion portion 13 through which the first support shaft 9 of the adjustment piece 12 is inserted are formed, and the mounting bracket support piece 14 which is connected to the insertion portion 13 and abuts on the back surface of the base 5 is formed. At the same time, a mounting bracket 17 having a bolt insertion hole 15 and a fixing piece adjusting screw insertion hole 16 formed therein, and an insertion portion 18 for inserting the second support shaft 10 of the adjustment piece 12 are formed and connected to the insertion portion 18. One end is in contact with a wall material W sandwiched between the step portion 3 of the side plate 4 of the base 5 and the other end is fixed to a fixing piece adjusting screw insertion hole 8 formed in the bottom plate of the base 5 and the mounting bracket 17. A fixing piece 20 which is in contact with a fixing piece adjusting screw 19 inserted through the piece adjusting screw insertion hole 16; The bolt insertion hole 11, the bolt insertion hole 15 drilled in the mounting bracket 17, and the bolt insertion hole 7 drilled in the vicinity of the four corners of the bottom plate of the base 5 are aligned with each other, and the bolts 22 are sequentially inserted through the spacers 23. And tightened with a wing nut 24 to fix it to the opening of the wall material.
[0009]
In order to attach and fix the distribution board 1 for a house to the opening provided in the wall material W using the attachment 6, the base 5 of the distribution board 1 for the housing is fitted into the opening of the wall material W. By pushing the wing nut 24 attached to the bolt 22 via the spacer 23, the adjusting piece 12 and the fixing piece 20 are pushed all the way into the wall material W. When the wing nut 24 is further tightened, the end of the fixing piece 20 abuts against the back surface of the wall material W, and is held between the step 3 of the side plate 4 of the base 5 and the end of the fixing piece 20. It is supported without falling off from the wall material W. Further, the fixing piece 20 is fixed by tightening the fixing piece adjusting screw 19 inserted into the fixing piece adjusting screw insertion hole 7 of the base 5, and the housing power distribution board 1 is mounted on the wall by covering the base with a lid. It is attached and fixed to the material W. As shown in FIGS. 3 and 4, it is possible to cope with a wall material W having a different thickness without any difficulty depending on the tightening state of the fixing piece adjusting screw 19.
[0010]
In this embodiment, the wing nut 24 is attached to the bolt 22 via the spacer 23. However, the present invention is not limited to this, and the spacer may be omitted or a nut may be used instead of the wing nut 24. In addition, there is no problem in mounting the mounting bracket 17 to the base of the residential distribution board, not only by a method of fastening with screws or the like but also by a fitting type.
