<p>An automatic locking outlet is provided for use as an electric mains wall socket. The socket comprises a front plate 1 and a slider 3, each of which has formed therein holes 9 for the passage of pins of a mains plug. The slider 3 is slidable from a first position, in which it covers the outlet holes (as shown), to a second position, in which the slider holes and outlet holes are aligned by pushing with the plug pins against the action of a spring 7. Two spring-loaded slidable locking pins 12 enter the holes in the slider 3 when in the first position to lock it in this position. When a plug is inserted, the pins thereof push the locking pins out of the hole to allow the slider 3 to be moved to its second position and the plug pins to enter the outlet holes. When no plug is inserted, there is no access to the outlet holes, thus improving the safety of the outlet. <IMAGE></p> |
