Description

[Detailed explanation of the invention] (Industrial application field) This invention is used for electrical wiring work in buildings such as ordinary houses or high-rise buildings, and is mainly used for meter reading and other purposes. This invention relates to a mounting plate for a so-called meter box, which is a box for storing and installing a power meter.

(Prior Art) Conventionally, the mounting plate of this type of integrated power meter box has mainly been made of thick wood or plywood such as plywood.

(Problems to be solved by the invention) The above-mentioned conventional mounting plates are mainly used for attaching to the exterior walls of buildings, and are sometimes directly exposed to wind and rain, resulting in significant corrosion over time. It lacks durability, and the attachment and retention of the box becomes unstable at an early stage, which poses a safety problem.Also, the color fades early, impairing the aesthetic appearance, and wood or plywood is extremely expensive due to the lack of materials. Furthermore, there were various drawbacks in actual use, such as many problems in terms of workability such as drilling work on site. Therefore, this invention aims to eliminate the above-mentioned conventional drawbacks.
In particular, the present invention provides a mounting plate for an integrated power meter box that improves workability in wiring work.

(Means for Solving the Problems) In order to solve the above problems, this invention forms a cavity 2 on the back side of the mounting surface 1 with an insulating material such as synthetic resin, and the lower part of the cavity 2 is made of an insulating material such as synthetic resin. In the case where the wiring box 4 is provided with an opening 3 on the front side, a technical means is adopted in which the bottom part 5 of the wiring box 4 is formed separately so that it can be freely attached and detached.

(Function) With the above configuration, the bottom surface of the wiring box 4 can be opened by removing the bottom surface 5 of the wiring box 4. Wiring work on the side can be done easily and reliably, improving work efficiency.

(Example) Hereinafter, an example of the mounting plate for an integrated power meter box according to this invention will be described in detail based on the drawings.

Figures 1 to 4 show the bottom part of the wiring box formed separately, and 1 is the mounting surface;
Flat long holes 6 for attaching multiple boxes
and a plurality of holes 7 for fixing the mounting plate, a cavity 2 is formed on the back side thereof, and a sealing material 9 is provided on the back side of the peripheral wall 8 forming the cavity 2. 4 opens the front 3
This is a wiring box that is integrally formed at the lower part of the cavity 2, and has a short pipe 11 on its upper wall to which a wire insertion tube 10 is connected, and a wire insertion hole 13 having a temporary cover 12 that can be punched out on the back wall. In addition, the bottom part 5 of the wiring box 4 is formed separately so that it can be freely attached and detached, and this bottom part 5 is also provided with a temporary cover 14' to which a wire insertion tube (not shown) is connected. A short tube 14 is provided. The bottom part 5 has both side insertion pieces 17 engaged with engaging pieces 16 provided on both front sides of the bottom opening 15, and a locking male hook 18 protruding from the center of the bottom part 5 and the back side of the wiring box 4. Locking female hook 1 installed on the wall
It can be attached and detached by engaging and disengaging 9. Reference numeral 20 denotes a removal hole drilled in the female locking hook 19. If a tool such as a screwdriver is inserted into the removal hole 20 and the male locking hook 18 is pushed to release it from the female locking hook 19, the bottom surface can be removed. Part 5 can be easily removed. Note that 21 is an insertion hole bored in the upper wall of the peripheral wall 8 of the cavity 2 through which the electric wire insertion tube 10 is inserted, A is a box in which an integrated power meter is housed, and B is an outer wall in which the box A is installed.

5 to 8 show that the bottom part of the wiring box is divided into two and formed separately, and each bottom part 5', 5'' has an engaging piece 16', as in the embodiment described above. Insertion pieces 17', 17'' for 16'' and male locking hooks 18', 1 for female locking hooks 19', 19''
8", so that one or both of them can be freely attached and detached as required. In addition, in this embodiment, the wiring box 4 and the wire insertion tube 10 are integrally formed, and the wire insertion tube 10 is provided with a A tube connecting portion 22 is provided at the upper end opening of the tube 10.The other structures are the same as in the previous embodiment, so the same reference numerals are given and the explanation thereof will be omitted.

Note that the above mounting plate is made of synthetic resin or other insulating material.

In the above configuration, the mounting plate is fixed to the outer wall B by inserting nails or screws through the plurality of fixing holes 7, and the boxes A are fixed to the mounting surface 1 of the mounting plate through the plurality of elongated mounting holes 6. If you install it by screwing it in and remove the bottom part 5 of the wiring box 4 during wiring work, the bottom of the wiring box 4 will be opened, so you can connect the wiring from the short pipe 11 etc. on the top wall of the wiring box 4 and the electric wires on the back wall. Wiring work to the insertion hole 13 etc. can be easily and reliably performed. for example,
Connect the electric wire D on the input side to the electric wire insertion tube 10 and the short tube 11
The wires on the output side can be routed from box A through the wiring box 4 and into the building through the wire insertion hole 13 on the back wall. Wiring work can be done. After the above wiring work is completed, the appearance will be restored by fitting the bottom part 5 into the bottom opening 15 of the wiring box 4 from below. Note that after the wiring work is completed, the bottom opening 15 is closed without fitting the bottom part 5.
It is free to leave it open.

(Effect of the invention) As explained above, in this invention, the bottom part of the wiring box is formed separately so that it can be freely attached and detached, so that the work can be done easily by removing the bottom part during wiring work. In addition to being easy to use and significantly improving work efficiency, it is also easy to return to the current state after construction is completed, so the aesthetic appearance is not compromised, and the bottom part can be easily and reliably attached and detached. .
