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.
A cable terminal assembly comprising, a terminal including two mutually insulated terminal lug elements, a cable including two mutually insulated leads, each lead including three conductors spaced alternately and circumferentially with the conductors of the other lead, said cable having a terminal end formed of substantially straight end portions of said conductors longitudinally in alignment with the respective conductors' relative positions in which they are located in the cable adjacent said terminal end, first connector means secured to two of said conductors of each lead at said end portions and second connector means secured to the other one of said conductors of each lead, and means for securing said connector means corresponding to one lead to one of said terminal lug elements and said connector means corresponding to the other lead to the other terminal lug element, said connector means of each lead being alternately spaced with those of the other lead.
A cable terminal assembly comprising, a terminal including two mutually insulated terminal lug elements, a cable including two mutually insulated leads, each lead including three conductors spaced alternately and circumferentially with the conductors of the other lead, said cable having a terminal end formed of substantially straight end portions of said conductors longitudinally in alignment with the respective conductors' relative positions in which they are located in the cable adjacent said terminal end, plural connector means secured to said conductors of each lead at said end portions, and means for securing said connector means corresponding to one lead to one of said terminal lug elements and said connector means corresponding to the other lead to the other terminal lug element.
A cable terminal comprising a pair of semi-circular terminal lugs mutally insulated along a diameter, each lug having a flattened projection at one end, each projection being offset from each other along the diameter of insulation, and each projection providing recessed substantially parallel flat conductor connecting surfaces.
A cable terminal comprising a pair of mutually insulated terminal lugs each having a flattened projection at its inner end, each projection providing recessed parallel flat conductor connecting surfaces, one projection being diametrically offset from the other and an L-shape dual conductor connector connected to the inwardly offset surface and a single conductor connector connected to the outwardly offset surface with the single conductor nested between the conductors of the former.
