Abstract
Abstract Electrical pin and socket contacts, contained within connectors and interconnectable with one another by mating connection of the connectors, are sealed from the environment external to the interior of the connectors and the connection therebetween regardless of changing pressure conditions. Individual pressure-sensitive wire seals are utilized for each contact at the rear of the connectors and a two sided pressure-sensitive interface seal is utilized for sealing between two mating connectors. The pressure-sensitive wire seal at the rear of each connector includes a tubular portion jacketed in sealing contact on the conductor insulation, a cup-shaped flange opening toward the rear of the connector, a wiper land inwardly disposed of the cup-shaped land, and an interlocking engagement between the seal and the wire-receiving end of the contact. The pressure-sensitive interface seal sealingly engages each pin end of the pin contact and has a pair of cup-shaped seals facing each other and facing the front faces of the two connectors when each pin contact in one connector engages the socket contact of the other connector.
