Description

[Detailed Description of the Invention] The present invention provides a flat
The present invention relates to an outlet device installed at the intermediate portion, terminal portion, etc. of a conductor cable.

(Prior art) With the spread of office automation equipment, flat conductor cables have been installed under the carpet on the office floor as power wiring, and an outlet is attached to this to connect the power cord of the equipment. However, as shown in Figure 1, conventional outlet devices require a lot of work to connect the cable conductor to the outlet. That is, in the same figure, A is the floor surface, B is a flat conductor cable installed and wired between the floor surface and the carpet, and C is a shield plate made of a thin iron strip installed to cover the top surface of the cable. An iron base plate D is inserted between this cable B and the floor A, and a terminal block E is placed on the cable and fixed to the base plate D.
and the cable conductor, connect the connection terminal F on the top surface of the terminal block E and the outlet G with the conductor H, and also connect the iron wire on the edge C' of each shield plate C on both sides of the terminal block E. The structure was such that a pressure bar I was placed and attached to a base plate D using screws J. In such an outlet device, the outlet G into which the power plug of the OA equipment is inserted and the power cable B are connected by the conductor H, so the connection work of the conductor H is complicated.Furthermore, the shield plates C on both sides are connected to the pressure bar I, Since the screws J and the base plate D have to be used for connection, it is not easy to place the pressure bar I on the edge C' of the shield plate C and screw in the screws J.
