Abstract
An electrical cable connector seals an armoured electrical cable entering an explosion proof enclosure. The connector has less parts than existing connectors and takes less time to seal and assemble. The connector includes a rigid substantially tubular body portion with external threads at each end, the body portion has a passage therethrough for insulated conductors of an armoured electrical cable, an internal curved shoulder at one end of the body portion, and an internal taper at the other end of the body portion. A substantially tubular seal made from firm resilient elastomeric material passes over the armoured electrical cable, the seal has a substantially cylindrical inner surface, a frusto-conical outer surface extends from a small end, having a curved lip at the small end where the outer surface and the inner surface join, the curved lip is adapted to match the internal curved shoulder of the body portion. A first threaded cover holds the tubular seal to the body portion, a substantially tubular adaptor fits over the installed conductors and has an internal taper and an external shoulder that forms a sealant cavity between the two internal cavities, and a second threaded cover holds the tubular adaptor to the body portion.
