US Patent 10916906 Electrical connector assembly

An electrical connector assembly provides a hinge between two parts, such as an eye-piece part and an arm-piece part of augmented eyewear. The assembly includes first and second hermaphroditic connectors which are rotatable relative to each other. Each connector includes a conductive electrical terminal disposed on a non-conductive support. Each electrical terminal includes a main body and a flexible contact arm extending therefrom, and a contacting protrusion protruding from the contact arm. The contact arm can be flexed into a slot in the support. The contacting protrusion on each arm maintains engagement with the main body of the other connector during rotation.
