ABSTRACT:
A plug and socket system for electrical coupling of mains power, and safety socket cap devices are disclosed. The devices are an in line plug device FIG.2with a removable Semi hollow plug spigot6that houses removable electrical pin means9/10. A wire clamping means FIG.12/5; is attached to the Semi hollow plug spigot in one embodiment to retain wires to the pin terminals. A locking latch means FIG.2/7, locks both the socket and the plug together FIG.1by a cantilevered latch FIG.8, which is pushed into the socket and then is held in position by an internal slot inside the socket FIG.10/9. The latch is released by using leverage with one or more fingers inside a finger hold FIG.1/4, while depressing a button FIG.1/3or series of buttons FIG.9/2and the two devices can be separated. A water-resistant seal is created by the inclusion of an ‘O’ ring FIG.4/11. The Semi hollow plug spigot depth FIG.3/14into the socket device and the locking of the two devices creates a tamper proof chamber. A fault isolation means FIG.12/3is designed to prevent circuit components overheating.
