Abstract: A sealable electrical connector includes a housing having a passage therethrough which is open at both ends. A portion of the length of the passage defines a seal retaining region and includes an undercut edge. The seal retaining region receives an elastomeric seal ring which engages, and is retained by the undercut edge. A grip member which includes projecting electrical contacts is affixed to one end of the housing so as to seal the passage, to further retain the seal ring therein and to support the electrical terminal into the passageway. When a mating connector is inserted into the passageway for contact with the terminal therein, the sealing ring provides a sliding, seal with the mating connector against environmental conditions. Also disclosed is an improved ring seal providing uniform resistance to the insertion of a mating connector.
