Patent ID: 7563133

Claim:
A male connector interface comprising: a tubular housing comprising an inner surface defining a longitudinal bore along a longitudinal axis of the housing, the housing having a distal end; a central terminal disposed within the longitudinal bore of the housing; and a support member disposed on the inner surface of the housing and holding the central terminal within the longitudinal bore; wherein the inner surface of the housing comprises: a first inner diameter region having an inner diameter D 1 ; and an increased inner diameter region having a first end disposed directly adjacent the first inner diameter region and extending to the distal end of the housing for an axial length L 1 ; wherein the first end has an inner diameter D 2 , and D 2 >D 1 , wherein the distal end has an inner diameter D 3 , and D 3 >D 2 , wherein the first inner diameter region and the first end of the increased inner diameter region define a shoulder facing the distal end of the housing, and wherein the increased inner diameter region comprises a first tapered portion disposed at the first end and increasing in diameter toward the distal end for an axial length L 2 , the first tapered portion defining a first frustoconical portion of the longitudinal bore and wherein the first tapered portion lies at the first acute angle α 1 with the longitudinal axis, and wherein the increased diameter region further comprises a second tapered portion defining a second acute angle α 2 with the longitudinal axis, wherein α 2 >α 1 , the second tapered portion defining a second frustoconical portion of the longitudinal bore, and wherein the second tapered portion is disposed between the first tapered portion and the distal end.
