Abstract : A plug and receptacle combination is transformer coupled. There are no exposed contacts to the environment at any time, whether the plug and receptacle combination are mated or separated from each other. By encapsulating the primary winding and secondary winding separately in a respective plug and receptacle, mating and unmating can be accomplished while submerged in water. The inventive device is useful in any underwater activity in which a diver must attach a power cable to a power driven tool, light, pump, etc., while submerged. In addition submarines could have the receptacles installed outboard of the pressure hull to be used in the event it became disabled at a depth attainable by a diver. A diver could descend with cables and plug them into the receptacles providing power and communications to the stranded crew awaiting rescue. The inventions could also be used in the home as a safety device where no voltage would be exposed. Either the plug or the receptacle shown could be built into the wall. Whichever items is built into the wall would receive the power source and have the primary winding. (jes)
