Description

[Detailed description of the invention] (Field of industrial application) This invention relates to the improvement of the mounting plate of the integrated power meter box installed on the outer wall of the building during electrical wiring work in structures such as general houses and buildings. It is something.

(Prior art) The wooden veneer or plywood used as the mounting plate for the conventional integrated power meter box does not have a lead-in pipe for the electric wires drawn out from the electric appliances installed in the building, so it is not suitable for supporting the electric wires. It is unstable, inconvenient for electrical work, and the mounting plate itself corrodes and becomes unsightly. is made of synthetic resin, a cavity is provided on the back, and a wiring box is provided at the bottom of the mounting plate, and a wire insertion tube is stored in the cavity of the mounting plate and connected to the wiring box. By inserting it into the integrated power meter box, electrical work can be done safely and conveniently, and at the same time, corrosion can be prevented.

(Problem to be Solved by the Invention) The mounting plate according to the application filed by the above applicant has a structure in which a through hole is bored in the upper wall of the wiring box to connect the electric wire insertion tube that passes through the cavity to the wiring box. Hooks are drilled on both sides of the box, and a lid with a separate connection pipe is inserted into the hook on the upper wall of the wiring box, and the electric wire is inserted into the connection tube of the lid. Since the insertion tube is connected, its structure is complicated and takes time to manufacture.Also, during installation of the mounting plate, the lid may shift and the through hole and the connecting tube may become misaligned, or the lid may fall off and be damaged. Furthermore, the mounting plate may be misaligned with the wire insertion hole in the rear peripheral wall of the mounting plate, which poses a problem in terms of workability at the site.

The purpose of this idea was to solve the above-mentioned problems with the mounting plate by improving it.In particular, it was designed to simplify the structure by integrating a short tube for connecting the wire insertion tube to the wiring box, making it easier to manufacture the wire. To provide a mounting plate for a box for an integrated power meter, which improves the workability of installing an insertion tube.

(Means for Solving the Problems) In order to solve the above problems, this invention has an opening 3 in the front at the lower part of the box mounting plate 1 made of synthetic resin and having a hollow 2 in the back, and an opening 3 inside the box mounting plate 1. A wiring box 5 having a wire insertion hole 4 with a temporary cover is formed,
To provide a technical means in which a short tube 8 for inserting an electric wire through tube is integrally formed on the upper wall 6 of the wiring box 5 so as to maintain the same axis as the insertion hole 7 with a temporary cover provided at the upper part of the peripheral wall 1a of the mounting plate 1. do.

(Function) In this device, a short tube for inserting the wire through the wiring box is integrally formed on the same axis as the insertion hole at the top of the mounting plate, so the wire can be pulled out after the mounting plate is attached to the wall of a building. The inserted electric wire insertion tube can be accurately inserted into the short tube through the upper insertion hole, and the electric wire can be connected to the integrated power meter inside the box, 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.

In Figures 1 to 4, 1 is a synthetic resin mounting plate to which the integrated power meter box A is attached;
A plurality of long holes 9 for box mounting with the surface as a flat surface.
and a plurality of holes 10 for fixing the mounting plate, the back part of which is surrounded by the peripheral wall 1a to form a cavity 2, and the peripheral wall 1a
A pair of insertion holes 7 with temporary covers are formed in the upper part of the peripheral wall 1a for inserting the wire insertion tubes B, and a sealing material 1 is formed in the back of the peripheral wall 1a.
1.

Reference numeral 5 denotes a concave wiring box with an opening 3 at the front below the mounting plate 1, and wire insertion holes 4 with temporary covers that can be punched out on the left and right sides of the back and bottom side of the wiring box, respectively.
4', 4', and the wire insertion hole 4' on the bottom side has a short pipe 12 to which the wire insertion tube is connected from below.
are integrally formed.

In the wiring box 5, a short tube 8 for tightly inserting the electric wire insertion tube B from above into the upper wall 6 is integrally formed on the same axis as the insertion hole 7 with a temporary cover in the upper peripheral wall 1a, and the electric wire is inserted therein. The electric wire that can be inserted into the pipe B is drawn out from the upper wall 6 into the wiring box 5. In the embodiment, the short tube 8
is provided with a step inside so that the electric wire insertion tube B can be inserted tightly up to the step, but the invention is not limited to this, and the inside of the short tube may be tapered to allow a tight fit. .

13 is an arcuate receiving part that holds the wire insertion tube B;
It is formed on the same axis as the insertion hole 7 and the short tube 8,
Reference numeral 14 denotes the base of a fixture (not shown) used to hold the wire insertion tube externally, and C denotes an outer wall to which the attachment plate 1 is attached.

In the above configuration, the mounting plate 1 is fixed to the outer wall C by inserting nails or screws into the plurality of fixing holes 10, and the boxes A are fixed to the mounting surface of the mounting plate 1 by inserting screws into the plurality of long mounting holes 9. Insert the electric wire through tube B into which the input side electric wire is inserted by punching out the temporary cover of the insertion hole 7 of the peripheral wall 1a, fit tightly into the short tube 8 of the wiring box 5, and insert it into the wiring box. The wire is pulled out through the short tube 8 and guided into the box A, and the output wire is routed from the box A again through the wiring box 5 and into the building from the wire insertion hole 4 on the back side, and performs any wiring work depending on the installation location. It can be carried out.

(Effects of the invention) According to this invention, the short pipe for connecting the wire insertion pipe was integrally provided in the wiring box, so the structure was simplified.
It is easy to manufacture, and since the short tube is provided on the same axis as the insertion hole in the upper circumferential wall, after fixing the mounting plate to the wall, the wire insertion tube can be immediately inserted through the insertion hole through the cavity on the back, and the short tube is installed on the same axis as the insertion hole in the upper peripheral wall. The wires can be fitted into the pipe and connected, and the wires from the insertion pipe can be pulled out to the wiring box, making the work easier and improving work efficiency. In addition, since the wire insertion tube is housed in the cavity at the back of the mounting plate, it looks good on the outside, and because it has insulation properties, it is electrically safe to connect the wires drawn out from the building to the integrated power meter through the mounting plate. Wiring work can be carried out to the storage box.
