3 so as to be fixed. Here, the solder connection terminals 60 of each terminal plate 35 project outward from the end of the casing 34. Each of the terminal plates 35 housed and disposed in the casing 34 houses the integrally provided blade portion 35a in a housing recess 32a formed in the body 32 and mounts each mounting piece 35b.
Is fitted to the body 32 by engaging with a locking concave portion 32b provided in the body 32. A lock piece 1 is provided on the upper surface of the body 32 for locking the harness connector 7 connected to the inlet block 30 so as to prevent the harness connector 7 from coming off.
3 are provided.

The lock piece 13 is fixedly attached to a mounting recess 18 formed in the upper surface of the cover 33 by fixing a fixing piece 13c, and a claw 13a formed at the tip end is formed in an opening formed at one end of the mounting recess 18. It has a structure protruding inside from 18a. Now, assuming that the harness connector 7 connected to the power cable 5 is connected to the inlet block 30, the claw 13 a of the lock piece 13 has a horizontal groove ( (Not shown) to prevent the harness connector 7 from coming off. In addition, lock piece 1
An operating portion 13b is formed on the other end of the connector 3. When the operating portion 13b is pushed into the mounting recess 18, the engagement state of the claw 13a with the lateral groove of the harness connector 7 is released, and the harness connector 7 is disconnected. It can be removed from the inlet block 30.

Hereinafter, an indoor wiring method using the wiring device 1 of the present invention will be described. In the above case, the casing 50 provided with one inlet block 30 is provided.
In the following description, a case in which eight outlet blocks 40 are provided in a casing 50 in which one inlet block 30 is provided will be described. Further, as the outlet block 40, two outlet blocks 40a to which a harness plug 8 provided in a branch cable 6 branched to a lighting fixture 4 as a load 2 provided on a ceiling or a wall surface are provided, and an outlet is provided. There are provided four outlet blocks 40b to which the harness plugs 8 provided on the branch cable 6 branched to the wiring device 4 are connected.
An outlet block 40 to which a harness plug 8 provided in a branch cable 6 branched to a switch 3 is connected.
c are provided. A branch cable 6 to the lighting fixture 4 as the load 2 is connected to the outlet block 40a, and a branch cable 6 to the switch 3 provided near the entrance 30 of the room is connected to the outlet block 40c. The lighting control of the lighting equipment 4 can be performed by 3. A lighting fixture 4 as bed lighting provided on a wall as the load 2 is connected to the outlet block 40a. Here, the outlet block 40 c to which the branch cable 6 branched to the switch 3 is connected is used for a three-way switch, and the outlet block 40 c is provided near the door 30.
In addition, any of the switches 3 provided on the wall surface near the bed 31 can control the lighting of the bed lighting. In the illustrated embodiment, the outlet blocks 40 shown in FIGS. 2 (a) and 2 (c) are not used, but various outlet blocks 40 are respectively provided according to the wiring conditions. 50 and used.

As described above, when the wiring apparatus of the present embodiment is used to perform indoor wiring, the power cable 5 and the branch cable 6 connected to the load 2 and the wiring devices 3 and 4 can be connected by the connector system. Wiring work can be easily performed. In addition, an erroneous connection prevention structure is provided that enables the connectors 7, 8 for connecting the load 2, the wiring devices 3, 4, the power supply cable 5, and the branch cable 6 to be connected only to the corresponding inlet block 30 and outlet block 40. Therefore, incorrect connection is not performed. Therefore, wiring can be performed easily and accurately even by a person who does not have specialized knowledge.

Incidentally, in the case of the indoor wiring, the branch cable 6 is not directly connected to the load 2 or the wiring devices 3 and 4, but is wired using a relay cable. Specifically, the harness plugs 8 are attached to the ends of all the loads 2 and the instrument cables 6a on the wiring instruments 3 and 4 side.
As a relay cable for relaying between the load 2 and the wiring devices 3 and 4 and the wiring device 1, a harness plug 8 is provided on the wiring device 1 side.
In addition, indoor wiring is performed by using a harness connector 7 attached to the load 2 or the wiring devices 3 and 4 side. In this way, the connection between the load 2 and the wiring devices 3 and 4 can be easily and reliably made by the connector system. If the extension cable 6b and the instrument cable 6a to be connected can be identified, the risk of erroneous connection is reduced.

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 of a predetermined length is prepared, the site Then harness connector 7
Since only the connection with the harness plug 8 is performed, the connection work becomes easy. Further, if the wiring device 1 of the present embodiment is installed in advance in various places indoors and relay cables having different lengths are prepared in advance, indoor wiring can be freely performed, and it is possible to change the floor plan of the room and the like. It is possible to easily cope with a case where the installation place of the wiring equipment is changed.

In the above description, the case where indoor wiring is performed by ceiling wiring has been described. However, floor wiring and wall surfaces using a double floor structure floor called a so-called system floor applied in offices and the like are described. The present invention can be applied to the used wiring and the like, and further can be applied to internal wiring in furniture such as an OA panel.
