Abstract

A terminal is disclosed for terminating the shields of a plurality of high speed cables each having an outer jacket and an inner metallic shield with a portion of the outer jacket removed to expose a portion of the metallic shield. The terminal includes a conductive ground plate portion. A gripping arm projects from the ground plate portion for embracing all of the plurality of high speed cables in direct engagement with the exposed portions of the metallic shields thereat. A solder connection is disposed between the gripping arm and the metallic shields.
