Abstract:
1. A mining cable coupler, comprising: a hollow body having a first end and a second end; an entrance fitting for an electrical cable at the first end of the body; an electrical connector mounting member having a plurality of electrical connector receiving apertures adjacent the second end of the body; and a plurality of electrical connectors mounted in corresponding ones of the receiving apertures, each of the electrical connectors comprising: an elongate electrical conductor extending from a first end in the hollow body that is configured to electrically connect to an electrical cable received through the entrance fitting to an opposite second end that has an exposed end face at the second end of the hollow body, wherein the first end of the electrical conductor is closer to the first end of the hollow body than the second end of the electrical conductor; and an insulating material surrounding the electrical conductor, wherein at the second end of the electrical conductor the insulating material defines a radiussed region on the exposed end face of the electrical connector that provides electrical stress relief at the exposed end face and wherein the second end of the electrical conductor includes either an electrically conductive pin portion protruding from the end face or a mating electrically conductive socket portion having an opening in the end face; wherein:
