Attorney, Agent or Firm: Ness; Anton P.
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). |

DETAILED DESCRIPTION The electrical connector of the present invention includes a first connector including a housing containing a plurality of socket terminals having socket contact sections exposed along a mating face, and a second connector including a housing containing a like plurality of pin terminals having pin contact sections exposed along its mating face, with the pin contact sections being complementary and electrically engageable with the socket contact sections upon connector mating.
The first connector's housing is of substantially rigid dielectric material, with the socket terminals retained within respective passageways therethrough from a wire exit face to a mating face.
The second connector's housing includes a rearward housing section of rigid dielectric material including a transverse body section, and a forward housing section of elastomeric material such as silicone rubber affixed forwardly of the rigid housing section and preferably bonded thereto.
The elastomeric forward housing defines rearwardly extending projections extending rearwardly through apertures of the transverse body section of the rearward housing to a wire exit face, with a respective pin terminal disposed through the center of each projection.
The elastomeric material of the projections is preferably bonded to body portions of the respective pin terminals, with the projections sealed thereagainst and against the aperture side walls of the rearward housing section's transverse body section therearound.
The elastomeric forward housing defines frustoconical recesses forwardly of the projections containing the pin contacts, for receipt thereinto of respective slightly frustoconical elongate silos of the first connector surrounding, holding and protecting the socket contact sections, where the first connector is made of substantially rigid dielectric material.
In one aspect of the present invention, the side walls of the recesses include at least one annular embossment, and preferably a plurality of annular embossments spaced therealong, to engage under compression the side walls of the silos upon full entry thereinto upon full connector mating, with the annular embossments expanding around the silos
