Abstract: A mining cable coupler has a hollow, cylindrical body. There is an entrance fitting for an electrical cable at a first end of the body. A plate-like insulator mount extends over the body near the second end and has insulator receiving apertures with annular recesses extending thereabout and inwardly from the second end of the body. There is a plurality of separate, tubular insulators. Each insulator has an annular outer projection extending thereabout and received within one of the recesses of the insulator mount. There is an annular seal fitted between each recess and the insulator therein. There is an elongated electrical contact within each insulator. A metal member has a tube extending about each insulator. An inner portion of the member is against the insulator mount. The inner portion has an aperture for each insulator smaller than the annular outer projection thereof and closely fitted about each insulator adjacent the projection. Fasteners releasably secure the metal member to the insulator mount.
