The floating socket cover must be rotated from the first position to a second position wherein holes in the socket cover are aligned with holes in the cover and then pushed toward the socket for moving prongs on the plug into holes in the socket. While prongs on the plug are moving into holes on the socket the prongs are covered by the floating socket covers to prevent electrical shock resulting from touching prongs of a plug that is partially plugged into the electrical socket.

Abstract: A guard for an electrical receptacle uses a rotating cover to mask the slots in the receptacle. Catch pins engage the cover and hold it in its closed position. Springs means, or similar, automatically return the cover to the closed position. In the preferred form, the catch pins engage the same slots which provide access to the slots in the receptacle, allowing the pins to be released by partially inserting the electrical plug. The cover can then be rotated by turning the plug to align with the receptacle slots. The catch pins move with a certain amount of independence, requiring that both be released separately to allow the cover to turn. The guard may be implemented using a modified housing on the receptacle or as a retrofit cover usable with an existing receptacle.

Abstract: A safety cover of simple and economical construction which will automatically return from an inactive position to a covering position responsive to removal of a plug from the related socket openings. This is accomplished by spring-leading the cover by a leaf spring element, preferably made integral at one of its ends with the cover. The leaf spring is anchored to the body of the end connector and extends at approximately a right angle to the cover. To move the cover from safety position to inactive position, it is pushed endwise in the direction of the leaf spring element, thereby bending and biasing the latter away from the end connector housing to which it remains attached. When the plug is later disconnected from the end connector, the biased leaf spring element returns the cover to the safety position.
