ABSTRACT:
A high voltage electrical connector assembly having a first connector (10) with socket terminals (14) in respective silos gradually tapered (28), matable with a second connector (110) having pin terminals (130) along a mating face (22,120). A forward housing section (118) of the second connector (110) is of elastomeric material to define sealing of the mating face (22,120) against voltage leakage paths that otherwise would permit generation of corona, upon compressive engagement with rigid material of the first housing (12). Each silo-receiving recess (140) is gradually tapered and contains axially spaced annular embossments (150), with generally the axial location of embossments of some recesses (140A, 140C) being staggered axially with respect to the embossments of adjacent recesses (140B). Each recess bottom (148) includes a forwardly extending flange (154) surrounding the pin contact section (144) to be received in a complementary recess (36) in the silo's leading end (30) and be longitudinally compressed to form a seal (166) against the abutting surfaces of the complementary recess upon full mating, adjacent and along the pin contact section (144).
