1. A galvanic corrosion-proof underwater electrical interconnect comprising:
a plug assembly (20) comprising:
a plug shell (24);
a plug insert body (26) mounted within the plug shell (24), the plug insert body (26) having a plurality of plug conductive terminals (22);
a threaded coupling nut (30) extending around a forward portion (24f) of the plug shell (24); and
a waterproof electrical cable (12) having a plurality of wires (14) connected to the plurality of plug conductive terminals (22); and
a rubber overmold (13) formed around a rear portion (24r) of the plug shell (24) and a portion of the waterproof electrical cable (12) forming a water-tight seal therebetween; and
a receptacle assembly (60, 460) comprising:
a first metal tubular member (72, 472) having a threaded forward portion (72f) adapted to threadedly engage the threaded coupling nut (30);
a second metal tubular member (74, 474);
a non-metallic outer body (70, 470) positioned around a rear portion (72r) of the first metal tubular member (72, 472) and a forward portion (74f) of the second metal tubular member (74, 474), the outer body (70, 470) having a gap-forming portion (70g, 470g) between opposing ends of the first and second metal tubular members (72, 472 and 74, 474) preventing contact between the first and second tubular members (72, 472 and 74, 474);
a receptacle insert body (66) mounted at least partially within one of the first and second tubular members (72, 472 and 74, 474) and having a plurality of receptacle conductive terminals (62),
wherein the plurality of plug conductive terminals (22) are adapted to contact the plurality of receptacle conductive terminals (62) upon mating engagement of the plug assembly (20) to the receptacle assembly (60, 460),
wherein the plug shell (24), coupling nut (30) and first metal tubular member (72, 472) are made of metal alloys having the same galvanic potential.
