An electrical socket assembly includes a plurality of pin receiving apertures passing through a wall mounted faceplate. The faceplate is enclosed by an integral cover panel which is spring biased to an open position. Engaging latch pins and a latch mechanism secure the integral cover panel in a closed position, and are adapted to be released in response to the insertion of a key into keyholes disposed in the side of the faceplate.

The invention claimed is: 1. A socket comprising a face plate provided with a plug receiving socket and at least one hinged cover panel, said at least one cover panel being movable about at least one hinge between a closed position concealing the plug receiving socket and an open position providing access to the plug receiving socket, said at least one cover panel defining an enclosure sized to accommodate a plug inserted in the plug receiving socket such that the plug is concealed behind said at least one cover panel in the closed position, said enclosure having at least one aperture through which a cord associated with said plug exits said enclosure in the closed position, said hinge being disposed on a first side of said enclosure, a latch means disposed on a second side of said enclosure, said latch means holding said at least one cover panel in the closed position in which said at least one aperture is not in said first side or said second side of said enclosure, the latch means being self-latching on movement of said at least one cover panel towards the closed position to secure automatically said at least one cover panel in the closed position, an actuator means for releasing said at least one cover panel, and a spring means biasing said at least one cover panel away from the closed position to move automatically said at least one cover panel to the open position when the latch means is released, and wherein the face plate and the at least one cover panel form an integral unit for connecting to a mounting box with said at least one cover plate attached to the face plate by said at least one hinge. 2. A socket according to claim 1 wherein said at least one cover panel is movably mounted with respect to a frame that extends around a marginal edge of the face plate and is integral with the face plate between the closed position, where the cover panel completely covers and encloses the face plate, and the open position, allowing access thereto. 3. A socket according to claim 2 wherein the latch means comprise a catch part engaging with a retainer part, and one of said parts is on or adjacent an edge of the cover panel and engages with the other part on or in the frame. 4. A socket according to claim 3 wherein one of said parts is resilient and can be deflected to engage the other part automatically when the cover panel is moved from the open position to the closed position and is deflected to disengage the other part by an electric actuator. 5. A socket according to claim 3 wherein one of said parts is resilient and can be deflected to engage the other part automatically when the cover panel is moved from the open position to the closed position, and is deflected to disengage the other part by a key operated release means. 6. A socket according to claim 5 wherein the resilient part is deflected to disengage the other part by rotational movement of the key operated release means. 7. A socket according to claim 5 wherein the resilient part is deflected to disengage the other part by axial sliding movement of the key operated release means. 8. A socket according to claim 5 wherein the key operated release means includes at least one formation insertable through an opening in the frame to engage the resilient part. 9. A socket according to claim 8 wherein the opening is protected by a movable shutter. 10. A socket according to claim 5 wherein the latch means comprises first and second latches that are engaged to hold said at least one cover panel in the closed position and are released by the key operated means to allow said at least one cover panel to move to the open position. 11. A socket according to claim 10 wherein the first and second latches are engaged and disengaged in sequence. 12. A socket according to claim 11 wherein the first and second latches are engaged in response to movement of said at least one cover panel in different directions relative to the frame. 13. A socket according to claim 12 wherein one latch is engaged by relative axial movement parallel to a hinge axis of the cover panel and the other latch is engaged by relative rotational movement about the hinge axis. 14. A socket according to claim 13 wherein said one latch is engaged first on closing said at least one cover panel and said other latch is released first on opening said at least one cover panel. 15. A socket according to claim 14 wherein means is provided to block relative axial movement parallel to the hinge axis in a direction to release said one latch when said other latch is engaged in the closed position. 16. A socket according to claim 15 wherein said blocking means includes a guide face to assist relative movement of said at least one cover panel. 17. A socket according to claim 15 wherein on release of said other latch, said one latch allows relative rotational movement of said at least one cover panel and frame to clear said blocking means and permit relative movement parallel to the hinge axis to release said one latch. 18. A socket according to claim 17 wherein said at least one cover panel is biased in a direction parallel to said hinge axis and is movable against the axial biasing to release said one latch. 19. A socket according to claim 2 further comprising a cable exit means including an opening in the frame for passage of a cable lead. 20. A socket according to claim 19 wherein the cable exit means comprises a cable tie arranged to transmit pulling forces applied to the cable lead to the frame.
