Abstract
Abstract A cable termination assembly for a kickless welding cable of the type comprised of a pair of opposite polarity mutually insulated lugs each having connected thereto a plurality of conductors which are helically and alternately wound is characterized by a terminal including a pair of mutually insulated terminal lug elements each having an offset extension with opposed recessed contact surfaces and cable conductor connectors secured to the terminal ends of the cable conductors, each connector having a contact surface for engagement with one of the recessed contact surfaces of the terminal lug elements, the relative configurations and orientations of the connectors and terminal elements when fastened together being such that the cable conductors at their terminal ends are substantially straight and parallel, and extend in alignment with their respective relative positions in which they are located in the cable adjacent the terminal ends. Thus, the cable conductors of opposite leads are commonly connected to respective terminal elements without bending, twisting and/or crossover of the conductors, thereby substantially reducing bending strains and reactance forces in the cable.
