US Patent 10950964 Electrical socket with contoured contact beams

An electrical socket and method of making an electrical socket. The socket has a cylindrical body defining a longitudinal axis and having opposite first and second end rings, a spaced contact beams, and an inner receiving area for accepting a mating pin. The first and second end rings being rotatably offset from one another with respect to the longitudinal axis, thereby twisting the contact beams into a hyperbolic geometry. Each beam has a middle section between first and second end sections and each contact beam. The middle section of each contact beam has a contour that defines an inner contact area such that the middle section extends further into the inner receiving area than the first and second end sections and such that the inner contact areas are positioned for contact with the mating pin when inserted into the inner receiving area.
