  • 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: 6609298
    Abstract: In an extrafine-strand-adaptable contact pressure blade, parts of the mutually opposed right and left side wall portions of a pressure contact part having a substantially U-shaped vertical section are formed by blanking so as to project inwardly in part in a substantially V-like shape, and the whole contact area of the right and left pressure contact blades with respect to the core of a wire is set at a value (equal to or larger than 0.15 mm2) which allows a slot width settable range to be determined by a pressure contact test to be larger than a tolerance range caused by a manufacturing tolerance.

  • Publication number: 20030115737
    Abstract: A cable punch assembly has a rod with first and second ends, and a base with first and second faces. The second end of the rod is connected to the first face. First and second connectors extend from the second face. Each of the connectors includes two laterally spaced wire pusher members that extend axially from the base to receive an insulation displacement contact between the pusher members as the pusher members force a wire into a wire receiving slot of the contact. Each connector engages a single wire, so the cable punch assembly may connect a plurality of wires to a plurality of insulation displacement contacts of a wiring unit. A blade may be positioned proximal each connector to cut off excess wire at the same time that the wires are inserted into receiving slots of insulation displacement contacts.

  • Patent number: 6532652
    Abstract: In a method for fabricating a wire harness with branch terminals, a flexible flat cable (FFC) (11) is first prepared by arranging multiple conductive strips (12) in parallel to each other at a predetermined interval, and by laminating a pair of base films (13) with the conductive strips between them. Then, a row of slots (14A) are formed between any two adjacent conductive strips at a predetermined distance from an end of the FFC, thereby defining a connection area (A) between the end of the FFC and the row of slots. Then, multiple connection terminals (16), each having a contact (17) and a plurality of projections (19), are fixed to the connection area of the FFC by causing the projections of each connection terminal to pierce through one of the conductive strips. Finally, slits (14B) are formed from the end of the FFC so that the slits extend between any two adjacent conductive strips and communicate with the associated slots.

  • Patent number: 6467164
    Abstract: A method is provided for connecting a terminal fitting and a flat conductor to achieve a high contact pressure between the terminal fitting and a conductive path. A FFC (10) has an insulation sheet (12) adjacent the end stripped to expose a conductor (11). The FFC (10) is inserted between first and second squeezing plates (22, 23) of a terminal fitting (20). Complimentary recessed/projected portions (32, 33) are formed on the outer surfaces of a pair of upper and lower press dies (30, 31) for pressing the terminal fitting (20). The terminal fitting (20) is pressed by the press dies (30, 31). Thus, the FFC 10 and the terminal fitting (20) are pressed together into a single unit and the squeezing plates (22, 23) are formed into a zigzag configuration.

  • Patent number: 6381839
    Abstract: A method secures wire to an electrical contact using an insulation displacement contact (IDC) strain relief cap. The electrical contact has a bifurcated end for engaging and retaining the wire and is engaged with the strain relief cap in securing the wire. The cap attaches to the contact via means on the electrical contact for engaging both the cap and the wire. The wire is secured by placing cap onto the contact, aligning the wire with exit holes, and turning cap until locked into place.

  • Patent number: 6247230
    Abstract: An improved impact tool head having separate and distinct pressing and cutting blades integrally molded therein. The impact tool head allows for independent and optimal material and dimensional design of the pressing blades and the cutting blades to minimize impact damage to a terminal block and to ensure longer useful tool life. Also, through the use of multiple components, the impact tool head is readily adaptable to a wide variety of different terminal block configurations. Furthermore, sets of pressing blades and sets of cutting blades may be formed with each set comprising a continuous piece of material in order to simplify manufacturing and to ensure uniformity of production. Additionally, the integral molded structure is designed to allow post-molding sharpening of the cutting blades in order to ensure blade uniformity to further improve blade durability.
