  • Transmission line cable applicator machine
    Patent number: 4295254
    Abstract: A machine for terminating flat multi-conductor transmission line cable to a connector. The machine includes a wire locator for providing semi-automatic positioning of cable shield wires and signal wires for terminations to a buss bar and connector tails respectively. The machine facilitates a method of mass termination of cable wires to a connector, which includes first stripping the cable to expose shield and signal wires, then positioning the cable wires in the machine for termination of shield and signal wires to the connector. The signal wires are terminated first to terminal tails extending from the connector. This is followed by the reverse bending of the shield wires over the buss bar and termination of the shield wires to the bar. In this fashion, the multiple wires of the cable may be simultaneously positioned, and respective sets of signal and shield wires mass terminated by the machine.
