Apr 26, 2006

Appl. No.:

11/411264

Inventors:

Ming Cheng - Memphis TN, US
George Robertson - Cordova TN, US

Assignee:

Thomas & Betts International, Inc. - Wilmington DE

International Classification:

H01R 4/66

US Classification:

439100

Abstract:

This invention pertains to a ground connector for grounding a conduit to an enclosure. The ground connector includes a plurality of integral ears extending from an outer wall of the connector with these ears configured to receive a ground wire therein. A locking nut portion, when engaged with the connector, urges the ground wire against the ears to thereby mechanically and electrically secure the ground wire to the ground connector. The connector is further configured with a plurality of locking teeth that engage the enclosure to thereby at least mechanically (and preferably electrically) secure the connector to the enclosure.
