Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for mounting a wiring sump for a distribution board and a power meter that are mounted on the inside and outside of a wall of a building.

Conventionally, as shown in FIG. 1, the distribution board and the watt-hour meter have mainly been separated by a wall 2 of a building 1, with the distribution board 3 installed on the inside of the wall 2, and the distribution board 3 installed on the outside of the wall 2. A power meter 4 is attached to the wall 2, and the distribution board 3 and the power meter 4 are wired via a pipe 5 extending through the upper part of the wall 2.

Therefore, in this case, the power supply wiring from the watt-hour meter 4 to the distribution board 3 requires a pipe 5 that penetrates the wall 2, and the penetration part of the wall 20 is sealed by an inch or so. This power wiring requires a considerable amount of cost and effort, as it requires some kind of treatment including real design.
There were drawbacks such as the fact that the power supply wiring ran along two walls, detracting from the inch-realistic design.

The purpose of the present invention is to provide a mounting structure between a distribution board and a watt-hour meter that allows power wiring from a watt-hour meter to the distribution board to be easily and inexpensively performed without impairing the inch-real design. The object of the present invention is to eliminate the above-mentioned conventional drawbacks.

Next, the configuration of the first embodiment of the present invention will be explained with reference to FIGS. 2 and 3.

Generally, the distribution board 6 and the electricity meter 7 are installed on the inside and outside of the same wall, separated by 8 walls, so the power wiring on the back side of the synthetic resin main body case 9 of the distribution board 6. The power supply wiring duct 10 is integrally formed with the case 9 to protrude from the position P, and also overlaps the duct 10 on the distribution board 6 side in the longitudinal direction with respect to the back surface of the metal main body case 11 of the electricity meter 7. The power wiring duct 12 that is loosely fitted in the case
1 through resistance welding, etc., and furthermore, ducts) 10 are attached to the installation positions of the distribution board 6 and the electricity meter 7 on the wall 8.
．． A hole 13 for passing the hole 12 is formed.

In this state, the wall 8 is placed on the outside of the wall 8.
When the main body case 11 of the electricity meter 1 is installed with the duct 12 inserted into the hole 13 on the surface, the wall 8 of the hole 13
The outside part of the surface is closed by the case 11, and the wall 8 is closed in the same way.
The power meter 7 is connected to the inside of the wall 8 along with the hole 13 on the wall 8.
With the duct 10 inserted into the side duct 12, the distribution board 6
When the main body case 9 is installed, the wall 8 of the hole 13 in this state
The inner side of the wall is closed by a case 9, and a power supply wiring duct 14 is installed between the main case 11 of the electricity meter 7 and the main case 9 of the distribution board 6, penetrating through the wall 8. Therefore, by passing the electric wire 15 through the duct 14, power wiring from the watt-hour meter 7 to the distribution board 6 can be easily performed.

Moreover, since the main body cases 9 and 11 of the distribution board 6 and the watt-hour meter 7 are attached to the wall 8, it is not necessary to take any special measures or labor to deal with both ends of the hole 13 on the wall 8 for the insertion of the duct 10.12. In addition, the power supply wiring does not run along eight walls, so the inch-real design is not compromised by the power supply wiring.

Next, FIGS. 4 and 5 show a second embodiment of the present invention,
In this case, the wiring ducts (23, 24) for inserting into the wall 22 shown in FIG.
is removably attached via the flange 25 and the elastic engagement piece 26, and the power wiring between the distribution board 16 and the electricity meter 17 is connected through the duct 27 in addition to the wiring through the duct 27 shown in FIG.
It is also possible to conduct branch wiring from the side of each case 18, 19 without using a wire, and to allow branch wiring to pass through the wall 22 through the split groove 28 formed in the duct 23 and the knockout hole 29 formed in the duct 24. Others are composition, action,
The effects are the same as those in the first embodiment.

In this embodiment, the elastic engagement piece 26 is attached to each duct) 2.
3.24 was formed on the upper and lower surfaces of each duct)23.
It can be formed on both the left and right sides of 24.

Next, the effects of the present invention will be explained.

The present invention provides for the shortest possible distance between the distribution board and the electricity meter installed outdoors by penetrating the wall between the back side of the electricity distribution board installed indoors across the wall of the building and the electricity meter installed outdoors. This is an installation structure between a power meter and a distribution board with a connecting wiring duct attached.

As a result, the present invention has the effect that the power supply wiring from the watt-hour meter to the distribution board can be easily and inexpensively performed without impairing the incremental design.
