Patent number: 10293397Abstract: To provide a metal wire and an electric wire of high mechanical strength and high ductibility that have sufficiently increased ductibility as well as sufficiently increased mechanical strength. A metal wire manufactured at least by being subjected to an extension in which a metal wire is extended in an axial direction, and having a hardness distribution in which hardness decreases toward a specific peripheral portion from a central portion in a cross-section orthogonal to axis, whereby a softened peripheral portion becomes to show a good malleability as well as a high resistance to cracking, so as to attain an improvement of mechanical strength and ductibility.Type: GrantFiled: September 24, 2014Date of Patent: May 21, 2019Assignees: Yazaki Corporation, The University of TokyoInventors: Junichiro Tokutomi, Kenichi Hanazaki, Jun Yanagimoto

Patent number: 9492856Abstract: An element wire, an electric wire including the element wire or the element wires, and a process for producing an element wire are provided, by which ductility of a core wire consisting of the element wires can be improved. The element wire is made of metal, at least one element wire being coated with an electrically insulating coating so as to constitute an electric wire. The crystal grains constituting the entire element wire are fine isometric grains. In the process for producing the element wire, an electrically conductive material is subjected to drawing so as to reduce a diameter of the material and subsequently subjected to successive bending along a longitudinal direction of the material.Type: GrantFiled: February 29, 2008Date of Patent: November 15, 2016Assignee: Yazaki CorporationInventors: Kenichi Hanazaki, Satoru Yoshinaga, Nobuhiro Tsuji

Patent number: 8383947Abstract: The present invention is intended to provide an enhanced conductor module capable of reducing a joint area between conductors, and a method for preparing the same. The conductor module has a pair of flattened circuits each of which comprises a rectangular shaped conductors, a pair of sheeted coverings disposed on both sides of the conductor, and at least one hole having a diameter smaller than a width of the conductor, and formed in the coverings so as to expose one surface of the conductor to outside the flattened circuit. The conductor of one flattened circuit is joined to the conductor of the other flattened circuit via the hole by application of electromagnetic welding.Type: GrantFiled: September 3, 2009Date of Patent: February 26, 2013Assignee: Yazaki CorporationInventors: Yoshitaka Sugiyama, Kenichi Hanazaki, Tomokatsu Aizawa

Publication number: 20100140325Abstract: An ultrasonic joining method and apparatus is provided, by which a large joined area can be obtained in a short period of operating time without damage. The ultrasonic joining apparatus includes a chip and an anvil, between which the first conductor of the first flexible flat cable and the second conductor of the second flexible flat cable as an object to be joined are put. An end surface of the chip facing the anvil is formed flat. The end surface is provided with a plurality of the first straight grooves. The first straight groove is formed extending straight. The plurality of the first straight grooves are arranged in parallel with each other.Type: ApplicationFiled: August 7, 2008Publication date: June 10, 2010Applicant: Yazaki CorporationInventors: Junichiro Tokutomi, Kenichi Hanazaki

Patent number: 6838620Abstract: One end of a terminal is formed in a tube shape, and a front end of a covered electric wire in which a part of a covering is peeled is inserted to the one end of the terminal, and is uniformly caulked from a periphery. A length of the peeled covering is shorter than a depth of the tube-like portion of the terminal. Accordingly, a part of the covering is received in the tube-like portion and caulked so as to serve as an operation of a packing, thereby preventing a water and an air from entering into an inner portion of the tube-like portion. Further, since the tube-like portion is uniformly caulked so as to be closely contact with the electric conductor, it is possible to obtain a comparatively large contact area, and it is possible to obtain a stable conduction.Type: GrantFiled: October 12, 2001Date of Patent: January 4, 2005Assignee: Yazaki CorporationInventors: Kazuhiro Murakami, Yukiko Shimada, Yuji Nitta, Kenichi Hanazaki

Patent number: 6644534Abstract: A process for joining metals is provided, by which a core wire of a coated electric wire can be securely joined to a metal having a plated layer on the surface thereof. The process is to assemble a wiring module 1. The wiring module 1 has a metal piece 2, a coated electric wire 3 and so on. A plated layer 6 made of tin is formed on a surface of a matrix 5 of the metal piece 2. The coated electric wire 3 has a core wire 7. An ultrasonic welding is carried out after placing a part 7a of the core wire 7 on the plated layer 6 of the metal piece 2. The plated layer 6 is melted so as to join the part 7a of the core wire 7 to the matrix 5 and the core wire 7 is broken off separating the part 7a therefrom. Another ultrasonic welding is carried out after further placing another core wire 7 on the part 7a joined to the matrix 5, so that the core wire 7 of the coated electric wire 3 is joined to the metal piece 2 through the part 7a of the core wire 7.Type: GrantFiled: January 28, 2002Date of Patent: November 11, 2003Assignee: Yazaki CorporationInventor: Kenichi Hanazaki

Patent number: 6527161Abstract: The object is to provide a method of connecting covered wires mutually which can solve increasing cost. Each of the covered wires 2, 3 is comprised of a conductor 4, 10 and a cover 5, 11. The covered wires 2, 3 are connected to each other by ultrasonic welding. An ultrasonic welding machine includes a chip and an anvil. The covered wires 2, 3 are placed between the chip and the anvil. The chip is located with the length of its cross section disposed along the length of the other covered wire 3. The chip and the anvil are pushed toward each other and the chip is vibrated. Friction heat is generated between the covered wires 2, 3. The covers 5, 11 are adhered together and the conductors 4, 10 are bonded to each other by ultrasonic welding.Type: GrantFiled: August 6, 2001Date of Patent: March 4, 2003Assignee: Yazaki CorporationInventors: Kazuhiro Murakami, Kenichi Hanazaki, Yoshihiko Watanabe, Hiroyuki Murakoshi
