a front plate 21 fitted by a machine screw 20 to the plug socket proper 19, which covers the space between the sidewall plates 10,10, and
a hood 24 fitted by machine screws 23, 23 to supporting pieces 22, 22 made up on the upper ends of the side wall plates 10, 10, which overlies upper ends of the side wall plates 10, 10, the front plate 21 and the rear plate 13.
in case of wiring on the floor surface covered with a carpet, etc. using the plug socket for a flat cable of this type, at first the location for fitting of the plug socket is decided temporarily. At this time, the plug socket is disassembled and the temporary decision for location is made with the base plate.
After that, the flat cable is wired temporarily so that the cable becomes neither creased nor loosened.
The location of the base plate is adjusted so that the flat cable can be fitted to the base plate without either creasing or loosening of the flat cable wired temporarily and then the base plate is fixed to the floor surface by machine screws. Also the regular wiring is made by fixing the flat cable wired temporarily to the floor surface.
Subsequently, an eyelet terminal is fitted to the conductor portion of the flat cable to connect the flat cable with the terminal of the terminal base of the base plate, the eyelet terminal is fitted to the terminal of the terminal base, and also the distributing cord of the plug socket proper is fitted to the terminal.
Thereafter wiring is completed by fitting the side wall plate, the front plate, the rear plate and the hood to the base plate and assembling the plug socket.
When wiring the plug socket for a flat cable which is wired in such a way with the flat cable, heretofore in use, there are disadvantages as listed below.
(1) It is difficult to work because of wiring temporarily and then regularly of the flat cable wired on the floor surface and locating temporarily and regularly the base plate of the plug socket.
(2) It is difficult and also inefficient when fitting the eyelet terminal for connecting the terminal of the plug socket flat cable at the job site.
(3) It is inefficient to disassemblethe plug socket, complete the wiring of the plug socket with the flat cable and then reassemble the plug socket at the job site.
(4) As the plug socket is made up in comparatively large size to make it easy to connect the terminal of the plug socket with the flat cable at a job site, it is apt to become an encumbrance.
(5) As the eyelet terminal fitted to the flat cable connected with the terminal of the plug socket cannot be fitted to the terminal unless the eyelet terminal is fitted in position, it is difficult to fit the eyelet terminal and also it is necessary to become skilfull in it.
A primary object of the invention is to provide a plug socket for a flat cable which permits the work of connecting a flat cable with the plug socket to be made easily and in a short time even by an inexperienced person.
Another object of the invention is to provide a plug socket for a flat cable which can be small sized and compact.
