Patent number: 7905745Abstract: A crimping terminal joined with an aluminum electric wire, in which when the crimping terminal is crimped to the wire, a conduct-purpose crimping portion and a wire-hold crimping portion are formed at a crimping portion of a wire barrel of the crimping terminal. The crimping portion of the wire barrel is formed so as a curvature thereof is projected upwardly in a direction of moving a crimping die and so as a crimp height increases and a compression ratio decreases towards an insulation barrel of the crimping terminal. The curvature is shaped to have a constant degree of curvature, and is shaped to form a quadratic curve as a result of strictly adjusting a crimping force.Type: GrantFiled: December 9, 2009Date of Patent: March 15, 2011Assignee: Yazaki CorporationInventors: Jin Watanabe, Yoshihito Aoki

Publication number: 20100263911Abstract: Provided is a composite electric wire, which is intended to realize a light weight and improve a mechanical strength at the same time and which is enabled to improve the reliability by avoiding the problem of oxide coating or electric erosion so that the electric wire may be easily handled for use as a car-mounted wire harness. The composite electric wire comprises an electric wire body (W) composed of center conductors (AL) and outer-layer conductors (CU) arranged to extend in a Z-direction along the outer circumferences of the center conductors (AL) and to enclose the center conductors (AL). In the electric wire body (W), the center conductors (AL) composed of copper-coated aluminum element wires (20) of a (1+6) number are sectionally positioned at the center portion of the electric wire body (W) in an X-Y plane, and the outer-layer conductors (CU) composed of twelve copper element wires (10) are positioned in the outer circumference portion arranged around the center portion of the X-Y plane.Type: ApplicationFiled: November 21, 2008Publication date: October 21, 2010Applicant: Yazaki CorporationInventor: Jin Watanabe

Patent number: 7690954Abstract: The present invention is to provide a connector terminal, which is crimp connected with an aluminum or aluminum alloy conductor having a large diameter, to be inserted into a terminal receiving chamber of a conventional connector housing designed for a copper conductor with less change of electrical characteristic and less modification. The connector terminal having the conductor of the present invention is widely adapted to a vehicle. The connector terminal crimping the electrical wire has a link portion longer than a link portion of a standard connector terminal so that an electrical wire crimp portion projects outwardly from a rearward face when the connector terminal is received in the connector housing. An insulation crimp portion is positioned spaced apart from the rearward face of the connector housing to prevent physical interference with the connector housing.Type: GrantFiled: December 30, 2008Date of Patent: April 6, 2010Assignee: Yazaki CorporationInventors: Jin Watanabe, Yasuyuki Kugimiya

Patent number: 7597596Abstract: The present invention is to provide a crimping terminal. The crimping terminal includes a crimping part, an insertion hole having a bottom provided in the crimping part and projections provided on an inner bottom surface of the insertion hole. When the aluminum electric wire is inserted into the insertion hole, the conductor of aluminum electric wire is relatively rotated against the crimping terminal. As a result, an oxide layer formed on a surface of the conductor is efficiently removed by the projections formed on the inner bottom surface. In low electric resistance condition, the crimping terminal connects with the conductor of the aluminum electric wire.Type: GrantFiled: January 22, 2009Date of Patent: October 6, 2009Assignee: Yazaki CorporationInventor: Jin Watanabe
