Abstract

PROBLEM TO BE SOLVED: To provide an indoor wiring structure for simplifying wiring construction and preventing in advance a cable from being overheated due to uneven distribution of the load for a specific wall outlet. SOLUTION: In an indoor wiring structure, a power distribution system where power is fed from a distribution switchboard 1 is divided into two portions, one of them is wired in a loop from the distribution switchboard 1, thus forming a loop circuit that is connected to a plurality of wall outlets 5 being provided at indoor rooms R1 and R2. The other part is connected to a bracket 4 of the rooms R1 and R2 and a switch 6 via one joint box 3 being provided in the attic from the distribution switchboard 1.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor wiring structure, and more particularly, to an indoor wiring structure in which wiring works such as lighting fixtures and outlets are concentrated around a joint box and connected to various parts of the house.

[0002]

2. Description of the Related Art In general, indoors such as houses are previously provided with connection wirings for a large number of electric appliances such as lighting fixtures and outlets. In these wiring works, a circuit is configured for each arbitrary section, and the circuits in that section are assembled around a joint box and connected to each part of the house. That is, in the conventional indoor wiring structure shown in FIG. 2, the power cable 2 connected to the distribution board 1 is connected to each of the rooms R1 and R2.
It is connected to a bracket 4 for lighting fixtures, a wall outlet 5, a switch 6 for lighting fixtures, and the like via a joint box 3 arranged at the back of the ceiling or the like. In this wiring structure, a joint box 3 is provided for each room to cover all of the connection wiring for electric appliances in that room.

[0003]

However, in the above-mentioned indoor wiring structure, the wiring for the outlet 5 is routed from behind the ceiling to behind the wall and connected to the outlet 5 arranged at a relatively low position on the wall. Therefore, there is a problem that the routing operation is not easy and the connection operation in the joint box 3 is complicated. In addition, the load on the outlet 5 tends to increase as the number of electric appliances or electric appliances increases. That is, unexpected loads may concentrate only on the specific outlet 5 depending on the arrangement position of the electric device in the room, and conversely, the outlets hidden behind the furniture are not used at all, and the load fluctuation due to each outlet may occur. However, there is a problem that the electric equipment is affected by a remarkable voltage drop. In addition, the cable connected to the overloaded outlet exceeds the rated capacity expected at the time of facility construction, and there is a risk of overheating, fire, and the like.

[0004] An object of the present invention is to solve the above-mentioned problems, and to provide an indoor wiring structure capable of simplifying wiring work and preventing overheating of a cable due to uneven distribution of a load to a specific outlet. It is in.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is to provide an indoor wiring structure in which connecting wires for electric appliances are gathered around a joint box and connected to various parts of the house. Divide the indoor wiring system into two,
One is wired in a loop from the distribution board to form a loop circuit connected to a plurality of outlets provided in each room indoor, and the other is provided from the distribution board to the attic.
This can be solved by an indoor wiring structure characterized by being connected to a bracket in each room and its switch via one joint box.

In the indoor wiring structure having the above structure, the load is relatively stable, and the luminaires and their switches mounted on the ceiling surface are wired via the space above the ceiling. Also,
Conventionally, outlets that were placed at a low position on the wall and had large load fluctuations are connected from the distribution board by a loop circuit, so the cable routing work is easy and it can cope with local overload conditions, In addition to preventing the voltage drop from affecting electrical equipment and the like, it is possible to reliably prevent ignition or the like due to overheating.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the indoor wiring structure of the present invention will be described below in detail with reference to FIG. FIG. 1 is a system diagram showing the indoor wiring structure of the present embodiment. The same parts as those in the related art are denoted by the same reference numerals, and detailed description will be omitted. As shown in FIG. 1, the indoor wiring structure of the present embodiment connects a distribution board 1 and a plurality of outlets 5 arranged at respective positions of the rooms R1 and R2 in a loop by a power cable 10, and A loop circuit is configured between the power board 1 and each outlet 5.

The power cable 10 is connected to each outlet 5
May be used according to the total load. Also,
The distribution board 1 is provided in each of the rooms R1 and R2 arranged behind the ceiling.
Are connected to a common joint box 3, and the joint box 3 is connected to a bracket 4 arranged on the ceiling surface of each room and its attached switch 6.

In the indoor wiring structure having the above structure, the load is relatively stable, and the lighting fixture mounted on the ceiling and the attached switch 6 are connected to the distribution board 1 via the joint box 3 arranged behind the ceiling. Receive power. Therefore,
The wiring work is limited to the work behind the ceiling, and the work efficiency of the wiring work can be improved. In addition, each outlet 5
Is limited to only under the floor, so that the work efficiency of the wiring work can be similarly improved. Also, since each outlet 5 is connected to the distribution board 1 by a loop circuit, it can cope with a local overload,
It is possible to reliably prevent ignition or the like due to voltage drop or overheating.

[0010]

As described above, according to the indoor wiring structure of the present invention, the indoor wiring system fed from the distribution board is divided into two parts, one of which is wired in a loop form from the distribution board. A loop circuit connected to a plurality of outlets provided in each room is formed, and the other is connected from a distribution board to a bracket in each room and its switch via one joint box provided on the attic. Therefore, the lighting is relatively stable, and the luminaires and their switches mounted on the ceiling surface are wired via the ceiling, and the load fluctuations are large. Since it is connected from the power board by a loop circuit, the cable routing work is simple. In addition, it is possible to cope with a local overload state, and it is possible to prevent an influence on an electric device or the like due to a voltage drop and to reliably prevent a fire or the like due to overheating. Therefore, the work efficiency of the wiring work is improved, and high safety can be ensured without overheating even if there is a local overload.
