Abstract
A cable assembly for use in electro-hydraulic control systems of mineral mining installations is composed of a cable with a plurality of electrical wires encased in a multi-layered armoured sheath and connectors at the ends of the cable. The cable is bonded to sealing bodies which fit in the connectors. The connectors are one-piece components each with a sleeve for coupling to the cable and a plug which fits into a socket of a complementary connector. The sealing bodies locate in the sleeves of the connectors and the wires pass through the sealing bodies to join with contacts supported by carriers in the plugs of the connectors. A screw-threaded ring clamps the cable to the sleeve of each connector.
