Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection box for indoor wiring which is routed under the floor or under the ceiling of a general house to connect indoor wiring for connecting lights, switches, outlets and the like.

[0002]

2. Description of the Related Art For example, when a general house is constructed, a lighting device, a switch, an outlet, or the like is connected to each other by an electric wire cable for each room to form a predetermined electric circuit.

[0003] Conventionally, at the time of indoor wiring, an operator cuts each of a plurality of electric wire cables to be connected at the site such as in the ceiling or under the floor, peels the covering material of the terminal, and uses a crimp connector to After connecting the terminals, the work of applying insulation treatment was performed. However, wiring work such as wiring and connection processing of electric cables is difficult and time-consuming in a narrow site space such as above the ceiling. There was a risk of quality defects in terms of insulation.

Therefore, in recent years, each electric wire cable is cut into a predetermined length, and the electric cable is connected to each other so as to form a predetermined electric circuit. Various assembled electric wires for indoor wiring have been developed and used. By using such an assembled wire that has been subjected to branch connection processing of the electric wire cable in advance, workability at the site can be improved and quality can be improved.

For example, Japanese Utility Model Laid-Open No. 3-30720 discloses that
There is disclosed an indoor wiring connection box in which a plurality of plug-in connectors are appropriately arranged in blocks and the plug-in connection parts of the connectors are connected by crossover wires to form a predetermined electric circuit. Further, JP-A-4-42720 and JP-A-4-325814 disclose a joint connector for connecting a power cable and a plurality of wiring cables,
There is disclosed an indoor wiring method in which the wiring cable and a harness connector for connecting a device cable of a wiring device are provided to facilitate wiring work and to cope with a change in wiring position.

As a device for connecting a plurality of conducting wires,
In Japanese Patent Laid-Open No. 9-29445, in a conductor fixing jig for fixing a plurality of conductors arranged in a grid, accommodating grooves for positioning and holding the conductors are formed in an intersecting shape, and the accommodating grooves are also formed. It is disclosed that by forming a through hole into which a pair of chips for pressure welding connection are inserted at the intersection point, it is possible to perform welding at an accurate position with high accuracy.

[0007]

In the conventional indoor wiring junction box and indoor wiring method as described above, since the wiring work is performed manually, the insertion position is incorrect at the wiring branch portion, etc. There was a risk of misconnection. In addition, since the connection between the cables is made by the connector, there is a problem that only a limited circuit configuration can be dealt with. Further, in the device disclosed in Japanese Patent Laid-Open No. 9-29445, the wiring work can be performed by a jig without manual labor, but only a predetermined circuit configuration can be manufactured, and an arbitrary circuit configuration can be manufactured. Was difficult to achieve. In particular, it was not possible to deal with the case where the circuit configuration had to be changed in various ways according to the specifications of a wide variety of products.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an indoor wiring junction box which can automate wiring work and can easily and flexibly cope with an arbitrary circuit configuration. Has an aim.
