Abstract: In an electrically insulated housing for an electrical connector which is to accommodate terminals in its passages, rear holders are provided over the housing for the prevention of rearward withdrawal movements of the terminals, in addition to retainers which are provided in the housings. Each rear holder has one or a plurality of projections in series which are engageable with the terminals by their substantially vertical displacement accompanied with the flection of hinges of an angle of less than 90.degree., viz., about 45.degree., which hinges connecting each projection to the housing with comparatively narrow and long extensions.

Abstract: An improved sealing arrangement is provided for a connector assembly having a terminal holder, terminals in the holder and joined by conductor wires and a housing in which the holder is disposed with the wires extending rearward through an opening. The holder has a support surface with channels of arcuate cross section for supporting the wires substantially in coplanar relation. The sealing arrangement is provided by inner and outer resilient seal members. The inner seal member is preferably annular and encircles the support holder between the holder support surface and the wires. The outer seal member encircles both the terminal holder and the conductor wires at least in partial coincidence with the inner seal member. The outer seal includes circumferential ribs for sealing engagement with the periphery of the opening in the housing. A face seal between the forward end of the holder and the housing seals pin terminals when inserted into receptacle terminals in the housing.
