Abstract

A port assembly comprising an outer housing having a first end and a second end, wherein the outer housing is configured to receive a coaxial cable through the second end, wherein the outer housing is configured to mate with a coupling member of a corresponding coaxial cable connector, a clamp disposed within the outer housing, the clamp including a first compression surface, a second compression surface, wherein the second compression surface opposingly corresponds to the first compression surface, and wherein the first compression surface and the second compression surface cooperate via axial compression to secure an outer conductor of the coaxial cable is provided. Furthermore, an associated method is also provided.
