Publication number: 20110036614Abstract: An aluminum electric wire includes an annealing conductor that is made up of elemental wires made of an aluminum alloy containing 0.90-1.20 mass % Fe, 0.10-0.25 mass % Mg, 0.01-0.05 mass % Ti, 0.0005-0.0025 mass % B, and the balance being Al and has a tensile strength of 110 MPa or more, a breaking elongation of 15% or more, and an electric conductivity of 58% IACS or more, and an insulating material covering the conductor. The wire is produced by casting an aluminum alloy prepared by rapidly solidifying a molten aluminum alloy having the above composition, producing the wires by subjecting the alloy to plasticity processing, producing the conductor by bunching the wires, subjecting the wires or the conductor to annealing at 250° C. or higher, and then covering the conductor with the insulator.Type: ApplicationFiled: October 23, 2008Publication date: February 17, 2011Applicants: AUTONETWORKS TECHNOLOGIES, LTD., SUMITOMO WIRING SYSTEMS, LTD., SUMITOMO ELECTRIC INDUSTRIES, LTD., SUMITOMO ELECTRIC TOYAMA CO., LTD.Inventors: Yasuyuki Otsuka, Masanobu Yoshimura, Koutarou Maeda, Jun Yoshimoto, Masashi Kimura, Taichirou Nishikawa, Misato Kusakari, Shinichi Kitamura, Hiroaki Takai

Publication number: 20060035533Abstract: A wiring harness for a vehicle includes a first wire, a second wire and a third wire. The first wire has a conductor formed by aggregating at least one high-tensile wire material and a plurality of conductive element wires. The second wire has a compressed conductor formed by compressing and aggregating a plurality of element wires. The wiring harness is formed by aggregating a cable including the first wire, the second wire. A cross sectional area of the conductor of the first wire is smaller than a cross sectional area of the compressed conductor of the second wire.Type: ApplicationFiled: August 1, 2005Publication date: February 16, 2006Applicants: AUTONETWORKS TECHNOLOGIES, LTD., SUMITOMO WIRING SYSTEMS, LTD., SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Yoshiaki Yamano, Toshio Shimizu, Koutarou Maeda, Takeharu Ito, Akira Hibasami

Publication number: 20050109530Abstract: An electric wire for a vehicle is provided whose tensile strength can be adjusted to various degrees without having to change the area of an electric conductor to satisfy various tensile strength requirements. The electric wire for a vehicle includes an electric conductor composed of a single central wire made of stainless steel and seven or more peripheral wires, made of copper or copper alloy, that are disposed in one layer on the periphery of the central wire with the peripheral wires joining with each other such that the peripheral wires surround the central wire. The diameter of the central wire is set larger than that of the peripheral wires. The area ratio of the electric conductor satisfies the relation area ratio of electric conductor={(A+B)/C}×100(%)?85(%) where A denotes a total of sectional areas of the peripheral wires, B denotes a sectional area of the central wire, and C is a sectional area of the electric conductor.Type: ApplicationFiled: September 9, 2004Publication date: May 26, 2005Applicant: SUMITOMO WIRING SYSTEMS, LTD.Inventor: Koutarou Maeda
