First Claim
Patent Images
1. In combination with an electrical connector assembly having an interfacial seal, said connector assembly of the type having a first insert having at least one passage extending from a forward face to a face of said insert;
- at least one electrical pin type contact;
means for mounting each pin contact in a respective passage so that a forward mating portion of the pin contact extends from the forward face of said first insert;
a second insert having at least one passage therein extending from a front face to a rear face of said second insert;
at least one socket type electrical contact;
means for mounting each socket type contact in a respective passage in said second insert so that the end of a forward mating portion of the socket contact terminates within said passage in said second insert at a predetermined distance X from the front face of the second insert; and
an interfacial sealing member comprised of a resilient material and having at least one passage therethrough, said interfacial sealing member mounted to the forward face of the first insert with each passage through said sealing member aligned with a respective passage in the first insert, said sealing member including a forwardly extending tower around each passage in said seal and extending around a portion of the mating portion of a respective pin type contact, the improvement wherein the interfacial seal is characterized by;
each of said towers having a configuration slightly smaller than the configuration of the passage in said second insert, said tower extending forwardly in its uncompressed state a distance Y which is greater than the distance X that the end of each socket contact terminates from the front face of said second insert, each of said pin type contacts mates with a respective socket type contact, each of the towers is located in a respective passage in the second insert and the forward end of each socket contact is engaged with a forward end of a respective tower, axially compressing and distorting each tower radially outwardly to cause outside walls of said tower to be in pressure tight relationship with the wall of the respective passage in the second insert.

Abstract
An interfacial seal for electrical connector assembly characterized by sealing towers (21) on a first insert (10) that are axially compressed and radially expanded by the forward end (43) of respective socket contacts in a second insert (20) so that the walls of each tower (21) are in pressure tight contact with the wall (32) of respective passages (33) in the second insert (30).
