Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distribution panel space duct for covering an electric wire conductor led out into the ceiling from an opening at an upper end of a distribution panel.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Patent Laid-Open No. 10-14052 discloses that an upper fixing tool for mounting an upper end of a space duct for a distribution board, which also serves as a cover of a distribution board, is attached to a ceiling position on a wall surface, and an electric wire is attached to the upper fixing tool. The electric wires are stored in the space duct for the distribution board as well as being inserted. However, when the ceiling has a peripheral edge, since the upper fixture is attached to the lower side of the peripheral edge, the electric wire conductor can be seen on the surface of the peripheral edge, which is disadvantageous in that it looks bad.

[0003]

On the other hand, for example, in Japanese Patent Laid-Open No. 6-327109, a notch is formed on the wall surface side of a distribution board space duct to allow a peripheral edge to escape so that the electric wire conductor is distributed to the distribution board space. It is stored in the duct. However, in this product, the openings on the ceiling surface side and the distribution board side of the distribution board space duct were the same size, and the positions from the wall surface were the same.
If the protruding portion of the peripheral edge is large, it is difficult to lead and introduce the wire conductor near the peripheral edge. On the other hand, if the opening of the space duct for the distribution board is enlarged, the protrusion from the wall surface becomes conspicuous.

Therefore, an object of the present invention is to provide a space duct for a distribution board in which an electric wire conductor can be housed so that the electric wire conductor can be housed in a visible manner without the protrusion from the wall surface being conspicuous and the electric wire conductor can be easily introduced and extracted. It is to be.

Reference numeral 32 is a mounting hole of the distribution board main body 31, 33 is a branch breaker, 33 'is a main breaker, 34 is a cover mounting portion, 35 is a power supply line which is an electric wire conductor, 36 is a load line, and 65 is a main body mounting screw. The power line 35 is pulled down from the ceiling surface 1 and guided from the second opening 13 of the distribution board space duct to the inclined portion 19 and passed through the first opening 12, or as shown in FIG. With the cover member 17 removed, the cover member 17 is passed through the first opening 12, and then is passed through the opening 11 of the upper fixture 30 and the wire guide portion 62 therebelow to connect to the power supply terminal of the main breaker 33 '. The load wire 36 connected to the load terminal of the branch blater 33 is passed through the wire guide portion 43 of the lower fixture 37 to pass between the floors of the double floor structure. Next, as shown in FIG. 5, the cover member 17 is attached and the lower cover 47 described later is attached.

The distribution board cover 44 covers the distribution board main body 31 and the power line 35 hanging on the wall surface 2 between the distribution board main body 31 and the upper fixture 30. A breaker exposure hole 45 is formed on the front surface of the distribution board cover 44, and an outer door 46 that closes the breaker exposure hole 45 in an openable and closable manner is provided. The lower cover 47 includes the distribution board body 31 and the lower fixing member 37.
It is a duct that covers the load line 36 between and.

FIG. 6 shows the engagement between the upper fixture 30 and the distribution board cover 44 which also serves as a duct. Upper fixture 33
The hooking piece 49 provided at the upper end of the distribution board cover 44 is hooked and attached to the locking groove 42 provided in the. The lower side of the distribution board cover 44 is attached with screws 52 as shown in FIGS. 8 and 10 with the connecting holes 51 being overlapped with the screw holes 50 of the cover attaching portion 34.
