Patent ID: 7497742

Claim:
A one-piece, controlled insertion force, elastic socket contact for electrical connectors comprising a rear part in the form of a rod defining a first cylindrical zone and a tubular front part comprising a second completely rectilinear cylindrical zone extending the rear part, open in the forward direction and divided by means of slots into elastic beams, a tapered spindle-shaped end zone in which the thickness of the beams gradually decreases in the direction of the open end of the tubular front part wherein the tubular part further comprises a cylindrical segment divided by means of slots into at least two elastic beams, said cylindrical segment having an outer surface with a cone frustum-shaped zone and wherein the cone frustum-shaped zone of said cylindrical segment comprises a variable moment of inertia element of the elastic beams for during the process of moving away in radial fashion, applying a large contact pressure needed to ensure electrical continuity to a pin contact of a first electrical connector into said one-piece elastic socket contact of a complementary electrical mating connector, said contact pressure being substantially uniform over the length of said cylindrical segment and thus said contact pin.
