ABSTRACT:
An adapter, mateable between two electrical connectors, has a shell with an internal chamber, and electrically-conductive socket assemblies extending through the chamber. The chamber has a vent to the external environment. A piston in the end of each of the socket assemblies is moveable between an extended position and a depressed position. Each socket assembly has one or more socket assembly vents. A flexible bladder within the chamber, filled with dielectric fluid, encases a portion of each socket assembly in which the socket assembly vents are located. The chamber vent allows communication of fluid between the chamber and the external environment. One end of each socket assembly has a contact that is engageable with a respective contact of the first electrical connector, and the other end of each socket assembly has a contact that is engageable with a respective contact of the second connector. When the piston is in the extended position, it seals the shell to prevent exposure of the socket assembly to the external environment. When the second connector is mated with the adapter, each contact pin of the second connector depresses a corresponding piston of the adapter and allows the contact pin to make electrical contact with the socket assembly. The second connector can be mated and demated with the adapter in an underwater environment because the adapter is pressure-balanced with the water in which it is submerged.
