ABSTRACT:
An electrical socket includes a socket housing which receives conductor pieces that are adapted to be electrically connectable to contact blades of an electrical plug. A rotary plate of a socket cover is provided in the front face of the socket housing. The socket cover further has a shaft projecting rearward from the rotary plate and extending into the socket housing. The socket cover is movable between a closed position, wherein the rotary plate blocks entry into the socket housing, and an open position, wherein entry into the socket housing is permissible, allowing plugging of the electrical plug into the electrical socket to achieve electrical connection between the contact blades and the conductor pieces. A control member engages the rotary plate when the socket cover is in the closed position to prevent rotation of the rotary plate relative to the socket housing. The control member can, however, be pushed inward to disengage it from the rotary plate, permitting rotation of the rotary plate from the closed position to the open position. A torsion spring is provided in the socket housing and is connected to the shaft and to the socket housing. The torsion spring returns the socket cover to the closed position when the electrical plug is pulled out of the electrical socket.
