Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the shape of a base of a distribution board for a house for housing various electric devices.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 8 to 10, a base 22 having at least a front opening, a frame 23 attached to the opening of the base 22, and a lid for covering the frame 23. The distribution board 21 for housing composed of the body 24 is provided with an embedded flange 30 for semi-embedding at a substantially central portion of the side surface of the base 22. A knockout hole 27 for inserting and exiting an electric wire 28 is provided on the upper side surface of the base 22 and used as an exposed / semi-embedded type.
Is formed to form a knockout hole 27 by punching out the cutout portion at the time of wiring work, and an electric wire 28 inserted and ejected from the knockout hole 27 is wired to an electric device 29.

[0003]

Therefore, when the distribution board 21 for a house is exposed and mounted, the side surface of the base provided with the embedded flange for semi-embedding is stepped, so that the internal space is narrowed. In addition, it did not look good.

[0004] When the residential power distribution panel 21 is mounted in a semi-embedded manner, the residential power distribution panel protrudes from the wall surface because the step of the embedded flange for semi-embedding is formed near the center of the side surface of the base. There are disadvantages that the number of parts is increased, the appearance is not good, and the internal space is narrow as in the case of the exposure mounting. In addition, the knockout hole is only provided on the upper surface for inserting and exiting electric wires on the base, so the knockout hole is small, making it difficult for the electric wires to come in and out, and wiring the electric wires coming in and out of the knockout holes to the electric equipment. At this time, the bending radius of the electric wire became small, and the wiring work became difficult.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned problems with the conventional residential distribution board, an object of the present invention is to eliminate a step of an embedded flange formed on a side surface of a base of a residential distribution board. The base of the base is formed to be approximately flat, reducing the portion of the distribution board for housing that protrudes from the wall surface, making it look good, expanding the internal space, and installing the electricity on the distribution board for housing. It is easy to carry out wiring work to the equipment, and also to provide a distribution board for a house that allows easy entry and exit of electric wires to and from the base, a base having at least a front opening, and In a residential power distribution panel comprising a frame to be attached and a lid covering an opening of the frame, a wire for inputting / outputting an electric wire to / from a side formed by the side and bottom of the base. A side knockout is provided and a bottom knock is provided on the bottom side of the base. The out portion is provided, the said side knockout portion and the bottom knockout unit is that the formation of the knockout hole so as to be integrated.

Further, in the above-mentioned residential power distribution panel, a side surface of the base is formed to be substantially flat.

[0007]

According to a first aspect of the present invention, there is provided a power distribution panel for a house, wherein a side surface knock-out portion having a substantially square cut is provided on a side surface of a portion formed by a side surface and a bottom surface of a base. The bottom side is provided with a bottom knockout part with a substantially square cut, and the side knockout part and the bottom knockout part are punched out to form a knockout hole, so that wires enter and exit the base. This has the effect of making it easier.

[0008] According to the residential distribution board according to claim 2,
By eliminating the step of the embedded flange formed on the side of the base and forming the side of the base almost flat, the part where the distribution board for residential use protrudes from the wall surface is reduced, it looks good, and the internal space is good. With the expansion, there is an effect that the wiring work to the electric equipment mounted on the distribution board for the house becomes easy.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of a residential distribution board according to the present invention will be described with reference to the accompanying drawings of FIGS.

A residential power distribution panel 1 includes a base 2 having an opening at the front, and a frame 3 attached to a peripheral edge of the opening of the base 2.
And a lid 4 covering the opening of the frame 3, and a side surface knock-out portion 5 having a substantially square cut is provided on a side surface of a portion formed by the side surface and the bottom surface of the base 2. A bottom-side knockout portion 6 having a substantially square cutout is provided on the side, and a knockout portion 7 is formed by punching a cutout portion in which the side-side knockout portion 5 and the bottom-side knockout portion 6 are integrated. The electric wire 8 is wired to the electric device 9.

In the present invention, the shape of the knockout hole 7 is substantially a square, but a circular shape or another polygonal shape may be used without any problem and may be appropriately changed without departing from the spirit of the present invention.

Further, a hole may be formed in the base 2 from the beginning without making a cut in the knockout hole 7, or the thickness of the base 2 may be reduced only in the knockout hole 7 as shown in FIG. 7 may be formed without any problem, and may be appropriately changed without departing from the spirit of the present invention.

A second embodiment of a residential distribution board according to the present invention will be described with reference to the accompanying drawings of FIGS.

The residential power distribution panel 11 includes a base 12 having an opening on the front surface, a frame 13 attached to the periphery of the opening of the base 12, and a lid 14 covering the opening of the frame 13. And the side surface of the base 12 is formed substantially flat.

[0015]

As described above, the distribution board for a house according to the present invention has a base having at least an opening on the front surface, a frame attached to the peripheral edge of the opening of the base, In a residential power distribution panel comprising a lid covering an opening, a side knockout portion for inputting / outputting an electric wire is provided on a side surface side of a portion formed by the side surface and the bottom surface of the base, and the base is provided with a knockout portion. By providing a bottom knockout portion on the bottom surface side and forming a knockout hole by integrating the side knockout portion and the bottom knockout portion, there is an effect that electric wires can be easily inserted into and out of the base.
