Abstract: A connector for use in deep ocean, high temperature and other high pressure environments has a housing defining an interior chamber filled with non-electrically conducting fluid wherein the cable termination is interconnected to a male or female contact apparatus. A pressure equalizing apparatus according to the invention includes a cylindrical sealing sleeve positioned adjacent to the interior of the chamber. The apparatus also includes a pair of mating sleeves positioned in the interior chamber, in spaced apart relationships, each having a cylindrical mating surface which sealingly mates against the interior surface of the sealing sleeve and a projecting sleeve receiving cylindrical surface. The sleeve receiving surfaces are juxtaposed opposite one another.
