And a screw is fastened to the fastening part 31-1 of the main body 31 of the sub connection body and is fixed as shown in Fig.

Accordingly, when the main cover 22 of the main connector 20 is to be opened, the electric power supplied through the connection line CL is cut off, It is possible to reliably control power supply to the three sub-connection ports 30-1, 30-2, and 30-3. Further, when it is desired to shut off the individual power supplied to each home, The sub-connection main body cover 22 of the three sub-connection ports 30-1, 30-2, and 30-3 can be opened to cut off individual power to each home.

On the other hand, through the lamp 50 installed in the mounting plate 10 can recognize the current power state intuitively can be processed quickly in case of failure, and can also improve the convenience of work.

As such, the power supply is controlled through the main connector 20 and the first to third sub connectors 30-1, 30-2, and 30-3, thereby safely managing power lines not normally used. It can be easily distinguished when the connector is not used, and can be easily distinguished when a failure occurs. The relatively simple configuration enables easy connection and repair of the wiring, and the power supply can be easily controlled.

In addition, by providing the input pipe 60 and the lead-out pipe 70 in the mounting plate 10, respectively, it is possible to safely and effectively protect the lead wire (L1) and the lead wire (L2), the lead wire (L1) ) And the leader line (L2) are not exposed to the outside, the wiring process is neat.

Although the present invention has been described in detail only with respect to the specific embodiments described, it will be obvious to those skilled in the art that various modifications and changes can be made within the technical scope of the present invention, and such modifications and modifications belong to the appended claims. .
