Abstract:
An interposer assembly comprising:A) a plate formed from insulating material, the plate having a flat top surface, a flat bottom surface extending parallel to the top surface and a substantially uniform thickness; B) a contact passage extending generally perpendicularly through the thickness of the plate from the top surface to the bottom surface; and a projection located in the passage, the projection extending outwardly from one side of said passage toward an opposing side of the passage, the projection having a first cam surface facing the plate top surface and a second cam surface facing the plate bottom surface; and C) a metal spring contact located in the contact passage, the contact formed from a wire having a metal core and a circumferential overplating of conductive metal surrounding the core and extending the length of the wire, the wire having a uniform circular transverse cross section; said contact having a central portion, a pair of spring arms extending to either side of the central portion, a pair of contact noses, each contact nose at an end of a spring arm, and a pair of retention legs, each retention leg extending from a contact nose to a rounded end, each contact nose between a spring arm and a retention leg, each contact nose having a convex surface facing outwardly from the plate and defining a high point, and a contact surface on each contact nose high point, each contact surface extending longitudinally along the nose and located centrally between the sides of the wire at the nose, the contact located in the passage with the central portion adjacent to said opposing side of the passage and the retention legs located on opposite sides of the projection so that the projection retains the contact in the passage.
