Coupler with combination locking and bonding ring

摘要

A bonding jumper is mounted on one facing surface of first and second coupling means which are threadably interconnected. The bonding jumper has a plurality of resilient detent members for bearing against the facing surface of the other coupling means to establish a redundant electrical bond between the first and second coupling means when the facing surfaces are axially drawn toward each other. A plurality of recesses is provided in the second surface for coacting with the detent means to yieldably resist opposing relative rotation in the unthreading direction.
