ABSTRACT:
An apparatus and method for butt splicing a pair of insulated electrical conductors by crimping an open-sided sleeve thereon. The apparatus comprises a frame, a wire cutter, a pair of laterally acting crimping jaws, a wire tensioning assembly, a sleeve feed assembly, a sleeve ejector, and a power cylinder, all of which are operably interconnected for sequential splicing operation. A connector sleeve is initially severed from a continuous chain thereof and is automatically positioned in each of the crimping jaw sets by the sleeve feed assembly. A pair of matching wires is then selected and pulled taut in a side-by-side manner, between the opposing side walls of each of the sleeves. Next, the power cylinder is actuated and in seriatim, the ends of the wires are trimmed to length by the cutters; the crimping jaws with sleeves retained therein are translated longitudinally of, and with respect to the wires, such that the trimmed wire ends are disposed wholly within the sleeve; the wire tensioning assembly places slack in each of the wire pairs; the crimping jaws are converged and securely crimp the sleeves onto the wires; the ejectors remove the crimped sleeves and spliced wires from the jaws; and another sleeve is automatically fed into each crimping jaw by the sleeve feed assembly.
