Claim:
A plug and socket system for electrical coupling of mains power comprising:— A moisture resistant appliance electrical plug and socket arrangement that comprises a plug device including a body having a semi hollow plug spigot with internal chambers which projects from the front face of the plug body being insertable into a corresponding chamber of the socket body with electrical contact plug pins that project from the front face of the semi hollow plug spigot to engage corresponding socket contacts in recesses at the bottom of the chamber of the socket body whereby the dimensions are such as to prevent the making of electrical contact until the shrouding has occurred, a) A plug device including a body having a removable and replaceable semi hollow plug spigot with internal chambers which project from the front face of the plug body being insertable into a corresponding chamber of the socket body having electrically conductive plug pins that project from the front face of the semi hollow plug spigot to engage corresponding socket contacts in recesses at the bottom of the chamber of the socket body, b) a socket device with a body having an internal chamber with an open face for receipt of the electrical semi hollow plug spigot, c) internal latching means provided between the plug body and the socket body which automatically engages into location to lock the plug to the socket when the semi hollow plug spigot is fully inserted and electrical connection is made, d) latch release means provided by a moveable release button projecting from the exterior of the plug body and being actuable to release the latch, permitting disengagement of the plug from the socket, whereby direct access is restricted from the exterior of the plug or socket bodies to the latch while the plug and socket bodies are engaged and interlocked, e) the plug contains an individual and optional axially aligned replaceable line current carrying fuse of chosen current rating better able to afford appliance protection and safety than reliance solely on the mains supply fuse, coupled and secured to a matching socket by a tamper resistant latch.
