Vibration resistant connector

A connector comprising:

• a connector body defining a cavity for housing a contact;
• a coupling nut comprising a first end portion of hollow cylindrical configuration defining a cavity in which a first end portion of said connector body is disposed, wherein the coupling nut is able to rotate relative to said connector body, said coupling nut further including a second end portion of hollow cylindrical configuration with a threaded inner wall to permit the connector to be coupled with an externally threaded mating connector via rotation of the coupling nut;
• and
• a friction member disposed in said cavity between said first end portion of said connector body and said first end portion of said coupling nut, said friction member having a coefficient of friction effective to reduce the possibility of said coupling nut rotating in a loosening direction due to vibration when said electrical connector is coupled with an externally threaded mating connector while permitting said coupling nut to be turned by hand, wherein
• the connector is configured such that, prior to the connector being coupled with an externally threaded mating connector via rotation of the coupling nut, the coupling nut imparts an inward, radial force on said friction member causing compression of said friction member, wherein the friction member, as a result of the radial force on said friction member, exerts a prevailing torque creating resistance between the connector body and the coupling nut preventing free-spinning of the of the coupling nut relative to the connector body.
