  • Patent number: 4375379
    Abstract: Flexible wire cable and the flexible wire cable by the steps of the process for manufacturing the flexible wire cable. The flexible wire cable interconnects between two spaced plurality of terminals. The terminals can be equally centered at opposing ends or can be spaced on different centers at opposing ends. A plurality of wire conductors are laminated between two sheets of insulation, each sheet having a thermosetting polyester adhesive coating, which partially and fully cures as a function of time-temperature-pressure. Each of the plurality of wire conductors are substantially surrounded internally one hundred and eighty degrees by each sheet of the insulation. The insulation is offset to provide an overlap at opposing ends or at only one end to provide a solder stop and controlled flexings of the wire conductors.

  • Patent number: 4114008
    Abstract: A sealed enclosure means for an electrical switching array and a method of preparing such an enclosure, with the switching array employing a plurality of generally rigid terminal contact pins which extend outwardly from a wall of the enclosure. The wall through which the terminal contact pins extend has a plurality of slots formed therein, with the slots having contact pin engaging edges. The material from which the wall is fabricated through which the terminal contact pins extend is generally resilient, and the slots which are formed therein to receive the contact pins have a width which is less than the pin thickness so as to cause the slot edges to temporarily form a lip seal about the surface of the pin. The terminal contact pins are then heated so as to cause the thermoplastic resilient material to flow to form a seal about the periphery of the contact pin.
