  • Patent number: 6730848
    Abstract: A connector device is shaped or formed to include bendable flaps for securing one or more conductors when the flaps are crimped. Typically, the connector device includes a base having an external surface that is eventually affixed to a complementary shaped surface. Accordingly, a conductor can be attached to the complementary shaped surface. For example, one or more conductors can be crimped via the connector device, which is thereafter attached to a complementary surface.

  • Patent number: 6710251
    Abstract: A fiber optic cable shield bond system provides reliable, weather resistant ground connections to the conductive shield of a fiber optic cable. The system includes a cable shield connector having a rigid, electrically conductive bond plate which is mounted to the fiber optic cable by at least one hose clamp. At least one ground connector in electrical communication with the bond plate penetrates the protective jacket of the fiber optic cable to electrically connect the bond plate to the cable shield. A harness assembly mounted to the bond plate may be connected to a ground point and thereby ground the conductive shield of the fiber optic cable.

    Abstract: A method of cable assembly with electromagnetic interference protection and a structure thereof are described. The cable comprises a transmission cable, a ground cable, and metal rings. The transmission cable connects the liquid crystal display and a motherboard of a notebook computer. The insulating cover of the ground cable is peeled off in at least one position of an insulating cover and exposes an internal conductive wire. The exposed positions correspond to positions of clips of the notebook computer. The conductive wire and the transmission cable are clamped in the metal rings, and therefore the electromagnetic interference noises transmit to a ground of the notebook computer.

    Abstract: A multicore cable includes a plurality of cables in parallel and is formed by fusion-welding the plurality of cables with a resin jacket. Each of the plurality of cables is formed by winding a shield around a signaling core wire, which is covered with an insulating material, and a grounding core wire. The resin jacket and the shield are stripped so that a stair portion is formed. The stair portion is coated with an electrically conductive adhesive. A vibration is exerted on the grounding core wire, thereby connecting the shield with the grounding core wire with the electrically conductive adhesive. Eventually, the shield and the grounding core wire are bonded with the electrically conductive adhesive. This allows an electrical connection between the shield and the grounding core wire to be maintained in a desirable condition, thus making it possible to suppress a characteristic impedance variation of the signaling core wire caused by an external factor.

A short length of insulation on each cable is stripped to expose the shield where the cables pass through the bracket.

  • Patent number: 6291771
    Abstract: A connecting structure includes a shield wire 1, a ground wire 2, an upper resin tip 15, a lower resin tip 16, and a low-melting welding material 17. First, the ground wire 2 is overlaid on the shield wire 1 in cross. Next, overlapping portions of the shield wire 1 and the ground wire 2 are interposed between the resin tips 15 and 16. By oscillating the resin tips 15 and 16 with ultrasonic waves, respective outside rinds 1d, 2d of the wires 1,2 are removed in the vicinity of the overlapping portions. A braided wire 1c of the wire 1 is electrically connected with a core line 2a of the wire 2 and, simultaneously, the resin tips 15 and 16 are welded to each other to seal up the vicinity of a connecting part S1. With the ultrasonic oscillation, a low-melting materials 17 is molten to flow into the connecting part S1, so that the braided wire 1c of the wire 1 is joined to the core line 2a of the wire 2 through the molten material 17.

  • Patent number: 6246001
    Abstract: Drain twisted wires of a plurality of shielded cables are connected with a ground wire without using a joint connector. In a grounding construction for grounding metal fiber braided wires of a plurality of shielded cables by connecting drain twisted wires 10a to 10f made of the metal fiber braided wires with each other and with a ground wire 11, sheaths of the plurality of shielded cables are stripped at positions corresponding to a sheath stripping position for the longest drain twisted wire. The drain twisted wires are bundled with the ground wire by a tape 12 from the sheath stripping positions P1. Resistance welding then is applied to ends of the twisted wires exposed from the leading end of the tape and to a core exposed from one end of the ground wire. The other end of the ground wire then is grounded.

  • Patent number: 6218619
    Abstract: A connecting structure for a shielded wire, including a shielded wire having a core made of a conductor, a core cover for covering the core, a braid provided around the core cover for shielding, and an insulating outer cover provided around the braid for covering the core, core cover and braid; and a shield terminal having a lead wire attached at an end to a terminal metal and conductively connected at a portion between the attached end and an unattached end to the braid of the shielded wire. This structure is formed by placing the portion of the lead wire of the shield terminal on the insulating outer cover of the shielded wire, placing a resin chip on the portion of the lead wire of the shield terminal, and applying an ultrasonic vibration so as to melt and disperse the insulating outer covers of the shielded wire and the lead wire, thereby forming a shielded conductive portion in which the shield terminal and braid are conductively in contact with each other.

  • Patent number: 6184471
    Abstract: A shielded cable includes core wires, an inner insulating cover for covering the core wires, a braided wire on an outer periphery of the inner insulating cover, and an outer insulating cover on an outer periphery of the braided wire. A shielded terminal has an insertion connecting portion coated with low-melting point joining material. The insertion connecting portion of the shielded terminal is inserted into the inside of the shielded cable from outside of the outer insulating cover such that the low-melting point joining material opposes the braided wire. With this condition, the shielded cable is subjected to ultrasonic vibration through a plurality of small protrusions of an ultrasonic horn over the outer insulating cover. As a result, the low-melting point joining material is melted so as to conductively connect the insertion connecting portion and braided wire to each other.
