Abstract: This invention relates to an extension socket and in particular to one including a base, a pair of conducting plates, a grounding plate, an overload protector, a light-emitting diode, a pulse absorber and a cover, whereby both sides of the extension socket may be connected with electrical plugs hence reducing its size and making it convenient to connect with electrical plugs in any position. Further, the overload protector and the pulse absorber may prevent the extension socket from being damaged by excess current passing therethrough.

Abstract: This invention relates to an improved receptacle and in particular to one which mainly comprises a base, a cover adapted to be engage with the base, and three conducting plates firmly mounted between the base and the cover, whereby the conducting plates may be firmly mounted between the base and the cover and will never be short-circuited thus making it feasible for industrial utilization.
