Abstract

A coaxial interconnect and contact are provided. The coaxial contact is patterned to define a plurality of openings along its longitudinal length. An inner surface of the contact can circumferentially engage an outer surface of a mating contact, wherein such engagement causes at least a portion of the contact to flex radially outwardly. The contact can also flex in the longitudinal or axial direction.
