Description

[Detailed description of the invention] (Field of industrial application) This invention is a mounting plate for a box for an integrated power meter that allows easy and accurate connection of electrical wire lead-in pipes in electrical wiring work in buildings such as general houses and buildings. Regarding.

(Prior art) Most of the mounting plates for conventional integrated power meter boxes are made of a single wooden board or a plywood board. Since the insertion tube for the electric wires cannot be pulled in, the insertion tube is buried in the wall of the building, and its end is pulled into the box from below the mounting plate. In this case, the means for supporting the wire insertion tube lacked stability, which was inconvenient and problematic for electrical work. Therefore, in Utility Model Registration Application No. 129098 filed by the applicant in 1981, the mounting plate was made of synthetic resin with a cavity in the back, and a short pipe was provided in the wiring box below the mounting plate, and this short pipe was accessed from the outside. I inserted the insertion tube into which the electric wire was drawn and wired it to the integrated power meter box.

(Problems to be Solved by the Invention) The box mounting plate applied by the above applicant has a complicated structure for mounting the lid body equipped with short pipes to the wiring box, and furthermore, the mounting plate cannot be mounted on the wall at the wiring work site. After fixing the wire, insert the insertion tube into which the electric wire was pulled out from the building into the short tube through the through hole at the top of the mounting plate, but since you cannot see the back of the mounting plate,
Depending on the insertion direction of the insertion tube, it may be difficult to insert the insertion tube into the short tube, and even if the insertion tube is removed from the short tube, it is not obvious, which is inconvenient.

The purpose of this idea was to solve the above-mentioned problems with the mounting plate by improving it.In particular, the mounting board was made to have not only a wiring box but also a wire insertion path integrated into it to make it sturdy and a connection port at the tip of the wire insertion path. To provide a mounting plate for a box for an integrated power meter, in which a lead-in pipe for electric wires can be visually and reliably inserted, and the electric wires can be wired to the box through the wiring box without being exposed on the back side of the mounting plate. .

(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 a temporary lid in place. A wiring box 5 having a wire insertion hole is formed, and the wiring box 5
To provide a technical means in which a wire insertion path 7 is integrally formed on the back surface of the mounting plate from the upper wall to the upper part of the peripheral wall 1a of the mounting plate 1, and a connection port 7a for a wire lead-in pipe is formed at the tip thereof.

(Function) This design forms a wire insertion path from the wiring box of the mounting plate to the upper peripheral wall, so that after the mounting plate is attached to the wall of a building, the wire lead-in pipe is opened into the peripheral wall of the wire insertion path. It is convenient to insert it into the mouth and wire the electric wire to the box via the mounting plate.

(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 Figs. 1 to 4, reference numeral 1 designates a synthetic resin mounting plate for mounting a box A for an integrated power meter.
A concave wiring box 5 with an opening 3 on the front side is formed below the mounting plate, and a wire insertion path 7 is integrally formed on the back side of the mounting plate from the upper wall 6 of the wiring box 5 to the upper part of the peripheral wall 1a. A connection port 7a into which the wire lead-in pipe B is inserted is formed in the upper part of the peripheral wall 1a at the tip of the wire insertion path 7.

Although the wire insertion passage 7 has a square cross-sectional shape in the embodiment, it is not limited to this cross-sectional shape, and may be formed into a rectangular shape, a circular shape, or the like. The connection port 7a at the tip of the wire insertion path 7 is tapered so that the wire lead-in pipe B can be tightly fitted therein, and a temporary cover that can be punched out is formed at the boundary between the connection port 7a and the wire insertion path 7. is preferred. In addition, on the back wall of the wiring box 5, there are wire insertion holes 4, 4 with temporary covers that can be punched out on the left and right.
In addition, electric wire insertion holes 4', 4' with temporary covers are provided on the left and right sides of the lower wall, and short pipes 8 are connected to these insertion holes 4', 4' to connect electric wire insertion tubes (not shown) from below. are integrally formed.

9 is a long hole for mounting a box on the flat surface of the mounting plate 1;
10 is a plurality of mounting plate fixing holes for attaching the mounting plate to the wall surface C; 11 is a sealing material on the back of the peripheral wall 1a; 12
is the base of a fixture (not shown) used to hold the wire insertion tube externally.

In the above configuration, the mounting plate 1 is fixed to the wall surface 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 screwing screws into the plurality of long mounting holes 9. Insert and install, surrounding wall 1 of mounting plate 1
Punch out the temporary cover in the connection port 7a that opens at the top of A, insert the wire lead-in pipe B into which the input-side wires are inserted into the connection port 7a, and insert the wires into the wiring box 5 through the wire insertion path 7. The wires on the output side are guided into the drawer box A, and are then routed from the box A again through the wiring box 5 to the wire insertion hole 4 on the back side to perform any wiring work into the building.

(Effects of the invention) According to this invention, a wire insertion path is integrally formed in the cavity on the back side of the mounting plate from the wiring box to the peripheral wall.
There is no need to assemble the insertion passage, the insertion passage is robust, and the connection port at the tip of the insertion passage is opened in the surrounding wall, so after fixing the mounting plate to the wall, you can directly connect the wire lead-in pipe to the connection port. You can connect securely by looking at the
Therefore, the wire lead-in pipe does not come off, and the wires in the lead-in pipe can be easily drawn out to the wiring box through the insertion passage without being exposed to the rear side, thereby significantly improving work efficiency. In addition, since the wire insertion path is formed in the cavity at the back of the mounting plate, it looks good in appearance, and because it has insulating properties, it is electrically safe to wire the wires pulled out from the building to the box via the mounting plate. Can be enforced.
