Abstract

A resilient connector interface provided with an outer conductor contact with a plurality of outer conformable members and an inner conductor contact with a plurality of inner conformable members. The outer conformable members provided with an outer conductor coupling surface on an outer diameter and the inner conformable members provided with an inner conductor coupling surface on an inner diameter. An alignment portion is provided at a proximal end of the outer conformable member. The alignment portion may be sinuous with respect to a longitudinal axis of the outer conformable member. An elastic bias member is positioned between the outer conformable members and the inner conformable members biasing the outer conformable members outward and the inner conformable members inward. The outer conductor coupling surface and the inner conductor coupling surface may be covered with a dielectric material to form a capacitive coupling interconnection.
