Abstract

A new-type power supply socket is composed of electrically conducting reeds, contacts, movable safety barrier, overcurrent protector and electric shock protector. Under the action of external pressure the electrically conducting reeds in socket can tightly contact with the eletrodes of plug to increase overcurrent capability and prevent poor contact, so that drive mechanism and pressure fastening mechanism are designed. An automatic ejection mechanism is used to automatically eject plug from socket and cut off power supply when overcurrent and electric shock take place, ensuring high safety.
