Galvanic corrosion-proof underwater electrical interconnect

Abstract

A galvanic corrosion-proof underwater electrical interconnect comprising a plug assembly and a receptacle assembly. The plug assembly comprising a plug insert body having conductive terminals mounted within a plug shell, a coupling nut, a waterproof cable having wires connected to the conductive terminals, and a rubber overmold formed around a portion of the plug shell and cable forming a water-tight seal therebetween. The receptacle assembly comprises a first metal tubular member having a threaded portion to threadedly engage the coupling nut, a second metal tubular member separated from the first tubular member by a non-metallic outer body positioned around and between the tubular members, a receptacle insert having conductive terminals adapted to contact the plug conductive terminals. The plug shell, coupling nut and first metal tubular member are made of metal alloys having the same galvanic potential.
