Patent ID: 7074064

Claim:
A male connector assembly for a matched male and female electrical connector pair, the male connector assembly comprising: a housing having a longitudinal axis and an opening on one end; a male pin assembly deployed in the housing, the male pin assembly including a plurality of male contact members sized and shaped for selectively making and breaking electrical contact with a corresponding plurality of female contact members on a corresponding female connector assembly; the male pin assembly coupled to a floating carrier, the floating carrier configured to displace along the longitudinal axis between a first floating carrier position and a second floating carrier position, the first floating carrier position located nearer to opening than the second floating carrier position; a substantially annular wiper piston deployed about the male pin assembly and interposed between the floating carrier and the opening, the wiper piston configured to displace along the longitudinal axis between a first wiper piston position and a second wiper piston position, the first wiper piston position located nearer to the opening than the second wiper piston position; and the wiper piston disposed to sealingly isolate at least one of the plurality of male contact members from the opening when the wiper piston is in the first wiper piston position.
