[57] ABSTRACT
A connector for terminating an electrical cable having a conductive sheath is disclosed. The connector includes a gland for receipt of the cable and a gland nut securable to the connector gland. Sealing structure supported between the gland and the gland nut effects a seal between the gland and the cable upon screw attachment of the gland nut to the gland. A sheath ground provides ground connection of the sheath to the connector upon initial insertion of the cable into the connector and also provide permanent mechanical and electrical connection between the sheath and the connector upon tightening of the gland nut to the gland.
