  • Patent number: 4242790
    Abstract: An electrical contact (10) for an electrical connector including a sleeve (20) and a plurality of axially-aligned fine wires (30), with each wire having an acutely angled end portion (32) at one end thereof and with the plurality of wires secured together at the other end to form a bundle (40). Preferably, the wires are secured together by a weld (50) formed by a capacitor (210) discharging across a gap (300) to the wires, although other securing methods could be used. The bundle (40) of wires then may be inserted into the sleeve of the contact (10) with the angled ends (32) forward in the sleeve (20) and the weld (50) rearward in the sleeve. Said sleeve then is crimped inwardly (25) forward of, or including, the welded portion, to hold the bundle (40) in place within the sleeve.

  • Patent number: 3943323
    Abstract: A bonding head for connecting the electrically conductive leads of a tape cable or the like to other electrical conductors. The bonding head, which applies heat and pressure to the electrical conductors and leads to bond them together, is an elongated member comprised of a material having high mechanical strength but low thermal conductivity which contains a conduit comprised of a material having low mechanical strength but high thermal conductivity. A heating element inserted in the conduit supplies heat to the conduit and bonding head. This arrangement provides a bonding head having a high mechanical strength and hence structural failure and deformation of the bonding head is reduced.
