Abstract

A connector assembly for terminating a cable having a cable shield is provided including an electrically conductive backshell and a shield assembly. The backshell includes a body that extends from a mating end to a cable end along a mating axis. The cable end includes a cable channel that extends through the body and holds an end segment of the cable therein. The connector assembly includes a shield assembly having a clamp system that is held within the cable end of the backshell and includes front and rear clamping members. The cable shield is terminated to the clamp system between the front and the rear clamping members. The connector assembly includes an EMI gasket that is electrically coupled to the backshell and held within the cable end of the backshell. The EMI gasket includes a backshell interface that engages the backshell and a clamp interface that engages the clamp system.
