Abstract: First and second connector units each have a contact chamber with a front wall having an opening closed by a stopper. Seals in the respective openings surround and seal the stoppers prior to mating. The stopper in the first connector unit is retracted into the housing during mating while the front wall of second connector unit is retracted into its housing during mating, pushed back by the front wall of the first connector unit, separating the stoppers from the end wall openings and allowing communication between the contact chambers through a passageway defined by the aligned openings. The seals in the end walls seal the passageway during and after mating. A contact assembly in the first connector unit moves transversely into alignment with the passageway for contact with a corresponding fixed contact assembly in the second connector unit as the units move into mating engagement.

Abstract: An underwater connector has a plug unit and a receptacle unit each containing a bladder member having an internal, oil-filled chamber in which a respective contact module is located. Each contact module has an end face having both electrical and optical contacts for contact engagement with corresponding contacts on the other module when the units are releasably mated together in an underwater environment. The bladder members each have a resilient forward end portion with an opening communicating with the respective chamber, and opposing, pivoted jaws in each unit are closed to compress the forward end portion to close and seal the opening when the units are unmated.

Abstract: An end seal assembly is mounted in a conduit or feedthrough body with a through bore of stepped diameter between its ends into which a fiber or wire-carrying metal cable extends. An inner end of the cable is stopped against a shoulder in the through bore, with at least one fiber or wire extending from the cable end out through the second end of the seal body. An end seal is seated at the outlet end of the seal body and has a through bore through which the or each fiber extends. The through bore is filled with epoxy material. The end seal is of a material having a coefficient of thermal expansion approximately equal to that of the epoxy material.

Each module has an end face having contacts for engagement with corresponding contacts on the other module when the units are releasably mated together. Each chamber has a resilient forward end with an opening communicating with the respective chamber, and an actuator in each unit compresses the forward end to seal the opening when the units are unmated. As the units are mated, the actuator in one unit is urged rearwardly and the forward end of the chamber in the other unit is urged rearwardly, such that each end opens to permit the module of one unit to pass into the chamber of the other unit, and into engagement with the other module so that all contacts are engaged for communication between the units.
