DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG.
The power is branched and supplied to the load 2 such as a lighting fixture and the wiring fixtures 3 and 4 such as a switch and an outlet, and is provided in various places indoors (for example, each zone in a house).
In the case of the present embodiment, the wiring device 1 is formed by blocking according to the application. For example, in the present embodiment, a block 1a for a feed line used when a plurality of power supply lines are branched, a block 1b for a switch circuit used when a load 2 is turned on and off by a switching operation of one switch 3 , And a block 1c for a three-way switch circuit used when the load 2 is turned on and off by switching operation of two switches 3 .

Each of the blocks 1a to 1c is provided at one end with a main connection 10a for connecting the power cable 5 and at the other end with a main connection 10b for connecting a feed wiring cable (not shown). It is. And each block 1a ~
From both sides of 1c, a plurality of sub-connecting portions 10c are provided for connecting the harness plugs 8 attached to the branch cables 6 for connection to the load 2 and the wiring devices 3 and 4 by a connector system.

The basic structure of each of the blocks 1a to 1c is substantially the same, so that the blocks 1a to 1c shown in FIGS.
Description will be made based on the structure of a. As shown in FIG. 2, the housing 11 of the block 1a is a body 1 made of synthetic resin.
1a and a cover 11b. The fixing between the body 11a and the cover 11b is performed by fitting holes 24a and 24a.
The staple 92 is swaged through 4b and assembled together. A main connection portion 10a formed at one end of the housing 11 is provided with an insertion port 1 into which a distal end of the power cable 5 is inserted.
2 and a quick-connecting terminal 100 disposed in the insertion opening 12.

A main connecting portion 10b formed at the other end of the housing 11 has the same structure as the main connecting portion 10a described above. Quick connection terminal 1 arranged in insertion slot 12
00. From one aspect of the block 1a, while projecting the three sub connection portion 10c _1, from another aspect Yes to protrude three sub connection portion 10c _2, the internal circuit is sub-connections are arranged respectively symmetrically Parts 10c ₁ , 10c ₂

Hereinafter, an indoor wiring method using the wiring device 1 of the present invention will be described. In the case of FIG. 3, the power supply line is branched into three at the block 1a, and an outlet 4 is provided at each branch end.
Are connected. The block 1b has a lighting device as a load 2 provided on the ceiling and a door 30 at the entrance of the room.
Is connected to a switch 3 provided in the vicinity of the lighting device, so that the lighting of the lighting equipment can be controlled by the switch 3. Further, the block 1c is connected to a bed lighting provided on the wall as the load 2, and provided near the door 30 at the entrance of the room and connected to the switch 3 for operating the lighting equipment on the ceiling. , And a switch 3 disposed on a wall near the bed 31 so that the lighting of the bed lighting can be controlled by any of the switches 3.

As described above, if wiring is performed indoors using the wiring apparatus of the present embodiment, the branch cable 6 connected to the load 2 and the wiring devices 3 and 4 can be connected by the connector system, and wiring can be easily performed. Work can be done. If this indoor wiring method is adopted, in a condominium or the like where the layout of the room and the installation locations of the wiring devices 3 and 4 are determined, if a relay cable 6b having a predetermined length is prepared, a harness can be used on site. Since only the connection between the connector 7 and the harness plug 8 is performed, the connection work becomes easy. Also, if the wiring device 1 of the present embodiment is installed in advance in various places in the room and the relay cables 6b having different lengths are prepared in advance, the indoor wiring can be freely performed, and the layout of the room can be changed. It is also possible to easily cope with a case where the installation location of the wiring device is changed or the like. The power cable 5 can complete the connection only by inserting the core wire into the main connection portion 10a and locking it to the quick connection terminal 100. Instruments 3, 4
Before the layout is determined, the main line can be connected in advance, and the connection to the outlet can be made after the layout is determined, so that an outlet facility can be provided at the level of an interior contractor.

In the above description, the case where indoor wiring is performed by ceiling wiring has been described. However, the present invention relates to floor wiring using a double floor structure floor called a so-called system floor applied to offices and the like. It can also be applied to wiring using walls and walls, and further to internal wiring in furniture such as OA panels.

[0015]

As described above, according to the present invention, a plurality of branch cables connected to a load or a wiring device, and a plurality of branch cables connected to a load or a wiring device are connected by a connector system. Since the main connection portion is formed by storing and arranging a plurality of quick connection terminals, the electric cable is connected by inserting the core wire into the quick connection terminal. Thus, it is possible to easily connect to the wiring device directly without any trouble, and it is possible to easily perform the wire connection work on site without trouble. In addition, while providing a main connection portion at one end and the other end of the block,
Since the sub-connection portion is provided on the side surface of the block, the insertion and extraction directions of the power cable and the feed wiring cable in the main connection portion and the insertion and extraction directions of the branch cable in the sub-connection portion cross each other, and the sub-connection portion When inserting and removing a branch cable, the insertion / extraction force is less likely to be applied to the connection between the main connection portion and the connection portion between the electric cable and the feed wiring cable. It is possible to prevent disconnection with the electric wire cable or the feed wiring cable.
Furthermore, since the main connection part is connected by the quick connection terminal method,
Core wire of the electric cable and the feed cables are firmly connected to the retaining is performed Rutotomoni housings <br/> ring it is not necessary to provide a leakage preventing structure of a connection in the main connection portion by quick connect terminals, simplifying the structure Is what you can do.
Therefore, the power cable and the
Feeding cable insertion / extraction direction and branching at sub-connection
When the cable insertion and extraction directions cross each other,
The connection part is a quick connection terminal method and the sub connection part is a connector method.
Connected to the main connection
More secure and secure wire and feed wiring cables
It can be held.
