Connector for use with metal clad cable
First Claim
1. A connector for terminating an electrical cable having a conductive sheath and a plurality of conductors extending therethrough comprising:
- an elongate gland having a cable receiving end, a conductor egressing and a longitudinal central bore axially extending therethrough for insertable receipt of said cable;
a gland nut movably securable to said gland, said gland nut being axially movable from a position adjacent said cable receiving end of said gland toward said conductor egressing end;
sealing means movably supported between said gland and said gland nut for effecting a seal between said cable and said gland upon said axial movement of gland nut; and
sheath grounding means movably supported within said gland adjacent said sealing means, said sheath grounding means being movable toward said conductors egressing end upon said axial movement of gland nut, said sheath grounding means further including an annular body having a first plurality of radially inwardly directed deflectable fingers of a first configuration for mechanical and electrical engagement with said cable sheath upon said insertable receipt of said cable, and a second plurality of radially inwardly directed deflectable fingers of a second configuration different from said first configuration for mechanical and electrical engagement with said cable sheath upon said axial movement of said gland nut with respect to said gland.

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.

12. A connector for electrical cable having a metallic sheath and plural conductors extending therethrough, said connector comprising:
-
an elongate gland having an internal bore therethrough for accommodation of said cable, said bore having a frustoconical extent tapering toward one end of said gland; sheath engagement means for mechanical and electrical engagement with said cable sheath; and urging means for moving said sheath engagement means into engagement with said cable sheath; wherein said sheath engagement means further comprises; a perimetrical body having a central opening therethrough; a plurality of elongate deflectable fingers extending from said body perimeter inwardly toward said central opening, each said finger having a distal extent and tapered side walls tapering toward said distal extent for engagement with said frustoconical extent of said bore upon said movement of said urging means to urge said fingers into mechanical and electrical engagement with said cable sheath. - View Dependent Claims (13, 14, 15, 16, 17)
