Abstract
An electrical coupling comprises a sealing element, a mechanical securing element, and load bearing members on either side of the mechanical securing element. The load bearing members each comprise upper and lower body halves, which mount to an inner member through which an insulated electrical cable runs. Between the upper and lower body halves and the inner member, an open weave fabric is secured, and the fabric extends onto the electrical cable beyond the load bearing member, so that when stress is applied to the cable, the fabric tends to squeeze down onto the cable, thereby bearing the stress on the cable. The mechanical securing element is preferably a bayonet mount, including an O-ring seal providing a water resistant seal when the connection is made up.
