ABSTRACT:
A safety socket for avoiding danger of shock due to insertion of alien article into the insertion hole. The socket includes two high and two low fixing seats. Two insulative slide boards are reversely disposed on the fixing seats side by side. The lower edge of each slide board is disposed with an elliptic slot for a pin member to pass therethrough, whereby the slide boards can be limitedly left and right slided. The socket further includes two long and two short leaf springs. The short leaf springs abut against front edges of the slide boards. The long leaf springs are fixed on inner walls of a housing of the socket opposite to the short leaf springs. The long and short leaf springs are disposed with convex contact points opposite to each other. When a plug is not inserted into the socket, the slide boards are pushed by the resilient force of the short leaf springs to the center of the socket away from the long leaf springs so as to open the circuit. While when the plug is inserted into the socket, the contact points of the long and short leaf springs contact with each other to close the circuit.
