ABSTRACT:
An anti-vibration arrangement for resisting unthreading rotation between a coupling nut and mated components is disclosed, consisting of a deflectable mandrel extending in a radial plane chordally across an interior bore formed in the coupling nut, which mandrel mounts a slidable ball. The mandrel passes adjacent an outer surface portion of one of the electrical connector components defining a clearance space of a smaller dimension than the ball, while the ball is axially positioned in frictional engagement with the surface portion on either side of the clearance space. Rotation of the nut is resisted only minimally in a direction tending to move the ball away from the clearance space while tending to be wedged by rotation in the opposite direction. On exertion of a turning force in the wedging direction sufficient to cause deflection of the mandrel, the ball passes through the clearance space which results in greatly reduced resistance to continued rotation in that direction enabling ready uncoupling of the connector elements.
