PROBLEM TO BE SOLVED: To pull off a plug without damaging it or a receptacle, in whichever direction it is pulled. SOLUTION: The plug 18 and the receptacle 1 are connected through a relay cable 7 equipped a wall-face use plug 8, a relay cord 10 and a receptacle-like plug 9, and a connection force of the wall-face use plug 8 and the receptacle 1 is set stronger than that of the plug 18 and the receptacle-like plug 9, so that the plug 18 and the receptacle-like plug 9 come off each other before the wall-face use plug 8 and the receptacle 1 do so. Further, in case a cable 17 connected to a first electric apparatus is pulled in various directions, the relay cord 10 follows suit to bend, so that force is always applied to a direction in which the plug 18 and the receptacle-like plug 9 are to be easily pulled off each other. Therefore, the plug 8 can be taken off in whichever direction it is pulled, without damaging the receptacle 1 or the plugs 8, 9, 18. COPYRIGHT: (C)2008,JPO&INPIT
