  • Publication number: 20230411044
    Abstract: There are provided a duplex twisted shielded cable and a wire harness, the duplex twisted shielded cable including: two insulated wires that are twisted together, each having a conductor and an insulator covering the conductor; a film wound spirally on the two insulated wires such that parts of the film overlap each other; a metal foil shield wound spirally on the film such that parts of the metal foil shield overlap each other; a metal braid provided on an outer periphery of the metal foil shield; and a sheath provided on an outer periphery of the metal braid. The film and the metal foil shield are provided as a separate member.

  • Patent number: 11062820
    Abstract: An extruded flexible flat cable includes conductors arranged side by side in a width direction of the extruded flexible flat cable. The conductors are spaced away from each other at a regular interval and an insulator is provided around the conductors by extrusion molding. A portion of the insulator located between the conductors, the portion having been sampled after the extruded flexible flat cable is subjected to a slide bending test, has a tensile strength being equal to or greater than 47.2 MPa. The portion has a percentage elongation being equal to or greater than 50/(0.5+2R), where R is a bend radius [mm] at which the extruded flexible flat cable is bent in the slide bending test.

  • Patent number: 9666333
    Abstract: A shielded electric wire includes an electric wire; a shielding member that forms a shielding layer by covering a periphery of the electric wire; a sheet-shaped member that covers a periphery of the shielding member; and a protective member spirally wound on a periphery of the sheet-shaped member. The sheet-shaped member includes a first sheet material and a second sheet material. One surface of the first and second sheet materials is formed with an adhesive layer. The first and second sheet materials have a width longer than a half circumferential distance of the shielding member provided on the periphery of the electric wire, and are stuck on the shielding member to sandwich the shielding member. The adhesive layers of the first and second sheet materials are opposingly stuck in extra length portions protruding the shielding member in a width direction.

  • Publication number: 20140110012
    Abstract: A partially molded corrugate tube integrally includes: a straight tube portion, a small-diameter bellows tube portion, and a large-diameter bellows tube portion of which diameter is larger than the small-diameter bellows tube portion and integrally continued to the small-diameter bellows tube portion, and configured to be bent firstly. The small-diameter bellows tube portion is integrally continued to an end of the large-diameter bellows tube portion, and the straight tube portion is integrally continued to the other end of the large-diameter bellows tube portion. The large-diameter bellows tube portion is formed shorter than the small-diameter bellows tube portion in a longitudinal direction of the tube. A thickness T of a hill portion of the large-diameter bellows tube portion is gradually reduced as the hill portion extends toward a tip.

  • Publication number: 20140110011
    Abstract: A corrugate tube with a clamp integrally includes a straight tube portion and a bellows tube portion and a locking clamp is provided on the straight tube portion. The straight tube portion provided with the clamp is thicker than the bellows tube portion. A slit in a longitudinal direction of the tube is provided in an opposite direction of the clamp. A hole is provided communicating with the slit. A groove or a hole is provided on the straight tube portion. A radius d2 of a hill portion of the bellows tube portion is sufficiently larger than a radius d of a valley portion of the bellows tube portion, and a thickness T of the hill portion is gradually smaller as the bellows tube portion extends toward a tip. The bellows tube portions are arranged in between straight tube portions, and the clamps are provided on required straight tube portions.
