High voltage low current connector interface with compressible terminal site seal

An electrical connector assembly suitable for high voltage low current transmission, comprising:

• a first connector including a housing including elastomeric portions surrounding each terminal site of said first connector, and respective socket terminals terminated to respective conductor wires disposed within respective passageways through respective said elastomeric portions and extending from a first mating face of said first connector to a wire exit face thereof, with socket contact sections of said socket terminals disposed within respective forwardly-extending silos of said elastomeric portions to socket contact leading ends exposed along said first mating face for electrical engagement, with said socket contact sections adapted to permit relative movement with respect to adjacent surfaces of said passageways through said elastomeric portions;
• a second connector including a housing of substantially rigid dielectric material and including passageways extending therethrough from a wire exit face to a mating face thereof, said housing including pin terminals terminated to respective conductor wires and disposed through respective said passageways, said pin terminals including pin contact sections complementary with and matable with respective said socket contact sections upon connector mating, and said housing including silo-receiving recesses extending rearwardly from said mating face complementary with respective said silos;
• each said silo defining an outer surface and each said silo-receiving recess defining an inner surface dimensioned for sealing engagement therewith upon full connector mating, and said inner surface of each said silo-receiving recess has a gradual taper and said outer surface of each said silo has a complementary taper;
• and
• each said silo extending a first selected distance, and each said silo-receiving recess having a recess bottom abuttable by said silo leading end and spaced a second selected distance from said second mating face, all such that said silo leading end abuts said recess bottom prior to full connector mating and is longitudinally compressed upon complete connector mating and is radially expanded for said outer surface of said silo to be compressed tightly against said inner surface of said silo-receiving recess upon full connector mating,
• whereby assured seals are established surrounding and adjacent said sites of said pin and socket terminals when electrically engaged minimizing formation of voltage leakage paths and inhibiting corona formation during high voltage low current transmission.
