Patent ID: 7083458

Claim:
A structure of a socket comprising a socket body, a pressing device, a positioning member, an oscillating member, a covering plate and an actuating member, wherein a fixing frame having at least slot in which is fitted said pressing device, said pressing device including an upper member, a lower member and a spring mounted between said upper and lower members, said positioning member is mounted in a mouth of said slot, a top of said positioning member has a through hole, a lower end of said positioning member is provided with a pin, said pin of said positioning member is inserted into a hole of said oscillating member which is made of metal, so that said oscillating member is rotatable about said pin, said positioning member has a shoulder which extends out of said fixing frame, said fixing frame is provided with at least a tubular member, said actuating member is provided with a downwardly extending pin and a downwardly extending plate formed with an inclined edge, said actuating member is fitted on said covering plate so that said downwardly extending pin goes through a spring into said tubular member, said actuating member has a top end protruded above said covering plate, said covering plate being formed at a bottom with grooves for engaging three conducting members made of copper such that when a plug is inserted into insertion holes of said covering plate, prongs of said plug will be in contact with said conducting members, and said upper plate will be depressed by said prongs thereby pushing said lower plate to force a lower end of said oscillating member to a horizontal flat position and moving a top section of said oscillating member forward to said prongs and therefore causing protrusions at a top end of the oscillating member to move forward and inert into holes provided at an end of said prongs.
