  • Patent number: 7228625
    Abstract: An intermediate portion of the outer insulation of a shielded electrical cable is removed near an end of the cable. A remaining small segment of the outer insulation at the cable end is moved axially inward along the cable to bunch up an exposed conductive braid of the cable. The bunched up braid is pinched to form a flattened, bell-shaped element on two opposite sides of inner conductive wires of the cable. The inner wires are attached to electrical terminals and the terminals are inserted into an insulator mounted within a conductive connector shield. The flattened elements are simultaneously aligned between opposite crimp arms extending from sides of the connector shield. The arms are crimped onto the flattened elements using an ultrasonic/vibration type crimping process or a shear lock crimping process. Since the flattened braid elements extend away from the cable, the crimping process is offset from the inner wires.

  • Patent number: 6883232
    Abstract: An outer sheath of a shield wire is stripped by a predetermined length from an end of the shield wire to expose a knitted layer of the shield wire. A shield stopper is mated over the exposed knitted layer until the shield stopper abuts against a stripped end of the outer sheath. A metal shell piece is preparatorily mated over an inner sheath of the shield wire while the metal shell piece expands the knitted layer. The shield stopper is clamped by a clamp means, and the mated metal shell piece is pushed to engage with the shield stopper. In the engagement state, the shield stopper overlaps a forward end portion of the metal shell with the knitted layer therebetween. A first cutter is guided by a pipe member so that the first cutter engages with an outer peripheral surface of the second cutter. Thereby, the shearing movement of the cutters cuts the exposed knitted layer near a rear end of the shield stopper.

  • Patent number: 5607321
    Abstract: In a process for fitting a round cable provided with a number of single wires with a multi-way, preferably flat, plug into which the single wires are placed, the single wires have their free ends stripped of insulation and are fitted with contacts. In such a process, assembly can be carried out in a cost-effective manner and the risk of damage to the small contacts is greatly reduced. Provision is made for the single wires to be placed alongside each other in a wire holder of the plug, for the ends projecting beyond the wire holder to be cut to the same projecting length and stripped of insulation to the same length and for a contact carrier to be provided with the corresponding number of adjacent contacts and connected to the end of the wire holder receiving the single wire ends, and for the opposing regions of stripped single wire ends and connection elements of the contacts to be interconnected to make electrical contact.

  • Patent number: 4884984
    Abstract: A crimp connector, comprising a socket housing having received therein a crimp terminal comprising a contact, a pair of claws for holding a stripped portion of a wire, and a pair of claws for holding an unstripped portion of the wire, said housing being provided; at the front end face thereof with an opening or said contact; at the top thereof with an opening through which the wire is inserted and crimpers to crimp the stripped portion holding claws and the unstripped portion holding claws are inserted; and at the bottom thereof with an opening through which an anvil to crimp said stripped portion holding claws is inserted. A method of attaching electric wires to the crimp connector is also disclosed. The present crimp connector makes it possible to attach wires in the state that crimp terminals have been built in a socket housing.

  • Patent number: 4870747
    Abstract: The assembly comprises a first slide (34) carrying a wire insertion tool (38) and a second slide (80) carrying support tools (92). As the slide (34) descends through a working stroke to cause the wire insertion tool (38) to insert a wire (W) into the wire slot (18) of an electrical terminal (10') of a multicontact electrical connector (2), support noses (96) of the support tools (92) which are in an open position, enter the mouths of the wire slots (18) of the next adjacent terminals. The wire insertion tool (38) continues to descend past the noses (96) to insert the wire (W) into the slot (18) of the terminal (10') and the support tools (92) close so that their noses (96) engage the terminals (10) on either side of the terminal (10') to be loaded with wire, thereby to restrain splaying of that terminal (10') as the wire (W) is inserted into its wire slot (18).

  • Patent number: 4774764
    Abstract: Centering strips, pluggable onto the contact blades of a wiring backpanel for receiving cable plugs, are provided with fastening disks in the region of openings in the floor of the centering strips through which the contact blades project into the centering strip, the fastening disk likewise including openings for plugging the contact blades therethrough. After the centering strip has been plugged, the fastening disks are located such that their inner edges of their openings cut into the contact blades and their outer edges cut into the floor of the centering strip. A positive fixing between contact blade, fastening disk and centering strip is thereby achieved.

  • Patent number: 4773157
    Abstract: A wire length having a very small diameter is terminated to a contact member by forming a groove in the contact member, disposing the wire length entirely within and along the groove, and striking the surface of the contact on both sides of the groove deforming the sides of the groove downwardly and inwardly into the groove firmly against the wire therein. The contact members can be made in lead frames on a carrier strip and have grooves formed therein, the wire can be placed in the grooves and terminated to the contact members in an automated assembly to make, for example, fuse components where wire segments bridge gaps between associated contact sections of pairs of the contact members, and the lead frames can have housings molded thereto while on the carrier strip.

  • Patent number: H1314
    Abstract: A process for preparing a cathode assembly comprising forming a hanger assembly by inserting an electrically conductive metal hanger core having a curved cross section into a metal tube jacket having a rectangular cross section such that the sides of the metal tube are displaced outward by the outer surface of the hanger core, effecting good electrical contact between the hanger core and the metal tube jacket. One edge of a metal sheet is rigidly attached to the metal tube jacket along its length, perpendicular to the tangent of the outer surface of the metal tube jacket. The cathode assembly produced according to this process has utility in a wide variety of electrolytic manufacturing processes, especially in the electrolytic refining of copper.
