US Patent 12021325 Electrical contact element with a support ring

An electrical contact element includes a common base and a plurality of spring arms extending away from the common base along a longitudinal direction. The spring arms are arranged around an opening in a circumferential direction and are spaced from one another in a contactless relaxed initial state. An end of at least two of the spring arms facing away from the common base forms an annular segment projecting in the circumferential direction on at least one side of the end. The annular segments form a support ring and mutually support each other in a fully compressed state.
