Strain relief clamp assembly

Claim 1

A wireless automatic self-locking anti decoupling nut for a strain relief clamp accessory for an electrical connector and a wire bundle, the clamp accessory adapted for attachment to an electrical connector, said automatic self-locking anti decoupling nut to prevent decoupling from said electrical connector due to vibration, comprising: a first member with an outer surface and mating means for mating with the electrical connector; a second member rotatably connected in said first member, said second member including electrical connector locking means for preventing relative movement between said second member and the electrical connector when engaged, said second member including strain clamp for clamping the wire bundle having wires connecting with the electrical connector; said first member including a concentric inner surface for at least partially receiving said second member; said inner surface including a first groove, and a channel connected between said first groove and the outer surface of said first member; said second member including a concentric outer surface and a second groove in said concentric outer surface; a locking member positioned in said first groove and said second groove by passing through said channel after said first groove and said second groove are aligned, said locking member prevents axial separation and allowing relative rotational movement between said first member and said second member; automatic means for withstanding vibration and unintentional relative rotational movement between said first member and said second member; said automatic means includes a spherical ball bearing for withstanding vibration and unintentional relative rotational movement between said first member and said second member, said concentric outer surface of said second member including three or more depressions having a spherical shape for receiving said spherical ball bearing; said ball spherical bearing includes at least one radial opening through said first member, an adjustable spring in said opening for adjusting the pressure exerted by said ball bearing means to change the torque required to provide relative rotation between said first member and said second member, and a spherical ball bearing positioned below said biasing means for movement into and out of said depressions; said first groove, said second groove, and said locking member are sized to position one side of said locking member in said first groove and another side of said locking member in said second groove, said channel including a blocking means for holding said locking member in said first groove and said second groove; said ball bearing means is an adjustable screw device with spring positioned between said screw device and said ball bearing; said electrical connector locking means is a gear type mating device, and said strain clamp has a clamping device to hold wire bundle in reference to the electrical connector and adapted to provide quick response time for preventing labor lost on all airplanes due to safety wiring to lock the accessory to the electrical connector.
