Abstract

A connector having a nut-body continuity element is provided, wherein the nut-body continuity element electrically couples a nut and a connector body, thereby establishing electrical continuity between the nut and the connector body. Furthermore, the nut-body continuity element facilitates grounding through the connector, and renders an electromagnetic shield preventing ingress of unwanted environmental noise.
