  • Patent number: 7003868
    Abstract: A copper welding rod is used in an arc-welding operation to form a bead that joins a copper starter sheet and a stainless steel hanger bar. The amperage level of the arc-welding equipment is set to generate heat at the weld site which is above the melting point of copper and below the melting point of stainless steel. This results in a welded joint between the copper bead and the hanger bar and a brazed joint between the copper bead and the starter sheet. Since brazing produces little or no fusion, the area of contact between the two dissimilar metals is limited to the interface between them, which significantly reduces the damaging effects of galvanic corrosion. Another improvement lies in the application of a corrosion-resistant metallic coating on the joint between the hanger bar and the starter sheet using a high velocity oxygen fuel flame spray technique.

    Abstract: A wire harness consists of electrical wires, a first resin sheet and a second resin sheet. The first resin sheet includes a recess formed so as to extend along a predetermined "three-dimensional" wiring route of the electrical wires. In order to manufacture the wire harness, at first, the recess is formed in the first resin sheet. Then, the electrical wires are arranged in the recess. Next, the second resin sheet is arranged on the first resin sheet so as to cover the recess and air contained in a space defined between the first resin sheet and the second resin sheet is sucked to the outside. Finally, the first resin sheet and the second resin sheet are joined to each other. Owing to the provision of the three-dimensional recess, it is possible to realize the wire harness having a three-dimensional configuration following to the actual wiring route of the electrical wires, so that the assembling property can be improved.

  • Patent number: 5868584
    Abstract: A method and connector to connect a first shielded cable to another electrical element, such as a second shielded cable, is disclosed. The first and second shielded cables comprise a cable shield applied over an insulated conductor. The connector comprises a contractible opening with a shield connector, such as a spring clip, located on the inner surface of the opening and contractible therewith. The opening can be resiliently deformable from a biased position, which permits easy insertion of the first cable, to an unbiased or contracted position, which can frictionally hold the first cable. To insert the first cable, the opening is biased to the biased position. Upon insertion of the cable to an inserted position, the opening is allowed to resiliently deform about the first cable, such that the first cable is frictionally held in the opening and the shield connector is in electrical contact with the cable shield of the first cable.

  • Patent number: 5864941
    Abstract: Various methods are described for assembling and/or coupling heater sections together for assemblage of heaters. The heater sections may be hot or cold heater sections having various geometries, dimensions, and specific electrical resistances. In one method, a cold heater section is assembled onto a pre-fabricated hot heater section with an oversized tube and pre-fabricated insulating cores. In another method, a pre-fabricated cold section is spliced onto a pre-fabricated hot section utilizing pre-fabricated semi-annular insulating cores and an oversized sleeve. In a further method, a first pre-fabricated hot section is spliced onto a second pre-fabricated hot section via an electrically conductive core and an oversized sleeve. These methods allow for the manufacture of stock lengths of hot and cold heater sections, that are then cut to length and coupled together. According to one aspect, the methods reduce tolerance errors in heater length.

  • Patent number: 5640765
    Abstract: A method for electrically connecting two electrical lines. Each electrical line contains at least two electrical conductors that are insulated from each other, and one common sheath surrounding the electrical conductors. One of the two lines (2) is equipped with insulated conductors and is flexible, while the other line (1) has a stiff, tubular metal sheath. To produce a moisture-proof connection between the conductors of the electrical lines, first the sheath is removed from a section of the conductors of the flexible line (1) and insulation is removed from the conductors so that the ends are bared. The conductors prepared in this manner are placed in a flexible rubber seal (10) containing passage holes to separate the conductors. After that, the conductors of the flexible line (1) are electrically connected to the conductors of the other line (2) which protrude from the metal sheath. A metal tube (13) is then positioned over the entire connection area.
