ABSTRACT:
An environmental electrical connector is provided in which the receptacle and plug members are individually formed as one-piece housings of resilient insulating material, having contact cavities formed with frontwardly disposed contact-retaining shoulders and rearwardly disposed resilient risers providing sealing engagement against lead-in conductors, with a sleeve at the mating end of the receptacle having an elastically expandable circumferential lip, and a complementary surface on the plug being provided for sealing engagement with the receptacle lip, as the front seal. A molded shape inside the sleeve and a matching cutaway portion on the plug prevent mating otherwise than in properly polarized relation, and matching longitudinal grooves on the outside of the connector members serve as visual alignment aids.
