Connector assembly with overmolded shielded housing
View Patent ↗A connector assembly is provided comprising a device including a conductive device shroud forming a device plug receptacle. A cable element includes a first stripped cable end portion exposing an internal cable conductor and a third stripped cable portion exposing a cable ground shield. A terminal element is mounted to the first stripped cable end portion. A ground busbar includes a cable mount end mounted to the third stripped cable portion and a ground terminal end. A conductive overmolded connector body is molded covering at least a portion of said third stripped cable portion and comprising a connector plug portion configured to fit within the device plug receptacle. The first stripped cable end portion protrudes out of the connector plug portion and the ground terminal end protrudes outside the conductive overmolded connector body such that the ground terminal end is placed in electrical communication with the conductive device shroud when the connector plug portion is placed within the device plug receptacle.
