Safety socket

A safety socket for avoiding danger of shock due to insertion of alien article into the insertion hole. The socket is disposed with three spaced partitioning boards defining three apartments. The partitioning boards are arranged according to the direction of the arrangement of the insertion holes of the socket. Three wedge-shaped insulative slide boards are disposed on the partitioning boards, which are left and right slidable within the apartments. Three short leaf springs and three sets of leaf spring seats are respectively disposed in the apartments. A leaf spring extends from each leaf spring seat to contact with a corresponding short leaf spring. The slide board is restricted to resiliently reciprocally slide within a slot formed on the leaf spring seat. By means of the leaf spring, when the plug is not inserted into the socket, the short leaf spring or the leaf spring always pushes the slide board in a direction reverse to the corresponding leaf spring, whereby the leaf spring is normally in an open state. Reversely, when the plug is inserted into the socket, each two corresponding leaf springs contact with each other into a powered on state. When an alien article is inserted into one insertion hole, the alien article will push the slide board on one side to move, whereby the insertion hole on the other side is powered on, while the insertion hole on the insertion side is not powered on so as to avoid danger of shock.
