DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. This housing complex is
It has two housing parts 21 and 22 at the top and bottom, and a common part 23 such as street lights and stair lights (not shown). A pull-in board 1 as shown in FIG. 2 is arranged outside the housing complex to supply electric power to each of the residential parts 21, 22 and the common part 23.

This retractable board 1 is provided with a box 2 having a front opening that is installed on the ground while being in contact with the outer wall of the housing complex, and a viewing window 3a provided at a position corresponding to the installation position of the watt hour meter described later. It is composed of a lid 3 that closes the front opening of the box 2. In this box, as shown in FIG. 3, a watt-hour meter 5 interposed in a power supply path to the common portion 23 on a mounting plate 4 on the upper side of the watt-hour meter 5 and a substantially side portion of the watt-hour meter 5 are arranged. The switch 6 for the common part, the switch 7 for the mains branching that supplies power to the residential parts 21, 22 to the mounting plate (not shown) in the middle part, and the telephone terminal block on the mounting plate 8 at the bottom. A telephone device 9 composed of 10 and a protector 11 and a cable TV connector 12 are provided respectively.

Electric power meter 5 on the upper part and switch 6 for the common part
Is for temporarily storing the power cable introduced from the lower surface of the draw-in board 1 and supplying power to each shared section 23. The shared section in which the lead wire from the watt-hour meter 5 is stored in the internal box 13 Electric power is supplied to each common part 23 via the switch 6 for use in the building, which simplifies the installation work and wiring work at the construction site, and the lead wire from the switch 6 for common parts is used in the housing complex. Power can be supplied by connecting the wall to a shared part (not shown) in the building, or by burying the lead wire in the ground and then connecting to the shared part 23 outside the building. Wiring work to the common unit 23 can be facilitated. This shared part switch 6 is composed of a main breaker 14 directly electrically connected to the electricity meter 5 and a plurality of branch breakers 15 branching from the main breaker 14 to each common part 23. The unit is a unit in which the opening / closing handle 6a of the switch 6 for the common part is projected to be housed in the internal box 13, so that the switch 6 for the common part can be attached and the wiring work can be simplified. The arrangement work of is easy.

The switch 7 for branching the main line in the middle portion is for accommodating the electric power cable once, and the electricity meter 24, 25 (see FIG. 4) and the distribution board 26, provided in each of the residential parts 21, 22. 27 (see FIG. 4) to supply electric power to the housing parts 21 and 22, and the open / close handle 7a is exposed to expose the inner lid 16
It is hidden in.

The lower telephone device 9 and the cable TV connector 12 are isolated from each other by a substantially F-shaped separator 17 formed by combining them separately from the main branch switch 7. Switch for shared part 6
In addition, the space for isolating the so-called high-power equipment such as the main branch switch 7 can be reduced, and the wiring work for each telephone equipment and cable TV can be facilitated.

As shown in FIG. 4, the power supply from the draw-in board 1 is performed by connecting the distribution line from the switch 6 for the common part to a street light or a stairway light (not shown) to supply power to the common part 23. Supply and supply the distribution line from the main branch switch 7 to each residential area 21,22.
The electricity meters 24 and 25 installed for each are connected to the distribution boards 26 and 27 to supply power to the residential units 21 and 22, respectively. Further, the telephone and the cable TV are distributed to the residential parts 21 and 22 through the telephone device 9 and the cable TV connector 12.

With the above configuration, the box body of the retractable board 1
Since the switch 6 for the common part is housed in 2, the lead wire from the switch 6 for the common part can be connected to the common part (not shown) in the building by connecting the wall of the housing complex. It is possible to supply electric power by burying the cable in the ground and then connecting it to the common section 23 outside the building, and it is possible to facilitate wiring work to the common section 23.

Further, since the electricity meter 5 and the switch 6 for the common part are provided in the upper part of the box 2 of the drawing board 1, each housing part is provided in the middle part and the lower part of the box 2 as in this embodiment. A space for accommodating the main branch switch 7 for 21 and 22 and the light electric equipment 9 and 12 for telephone lines and cable TV for each residential area 21 and 22 can be secured, and separate installation is required. The boxes can be shared, and wiring work at the construction site becomes easy.

Furthermore, since the switch 6 for the common part is unitized, the work of mounting and wiring the switch 6 for the common part can be simplified.

According to the present embodiment, the main branch switch is arranged in the middle part of the draw-in board, and the light electric devices for telephone lines and cable TVs are arranged in the lower part. You may arrange | position the main branch switch for each of the equipment in the lower part. Further, according to the present embodiment, the pull-in board is arranged upright on the ground, but it may be arranged while being attached to the outer wall of the housing complex.

[0021]

According to the draw-in board of the first aspect, since the switch for the common part is housed in the box of the draw-in board, the installation work and the wiring work at the construction site can be simplified, and the common part is shared. Power is supplied by connecting the lead wire from the switch to the shared area inside the building by connecting the wall of the housing complex or by burying the lead wire in the ground and then connecting to the shared area outside the building. Therefore, it is possible to facilitate wiring work to the common portion.

According to the pull-in board of the second aspect, since the electricity meter and the switch for the common part are provided in the upper part of the box body of the draw-in board, for example, the trunk line branch for each residential part is provided in the lower part of the box body. It is possible to secure a space for accommodating a switch and a light electric device such as a telephone line or a cable TV for each residential part, and in addition to the effect of claim 1, a box that has conventionally been required to be installed separately. Wiring work at the construction site becomes easy.

According to the draw-in board of the third aspect, since the switch for the common part is unitized, the work for mounting the switch for the common part and the wiring work can be simplified. In addition to the above effect, the work of arranging the switch for the common portion becomes easy.
