  • Patent number: 8771015
    Abstract: A terminal structure of a wiring harness for automobile use having a profound anticorrosive effect. A terminal member is fixed to a terminal portion of a coated electric wire such that a crimping portion that the member includes at its one end is crimped around a coating portion of the wire in a terminal region of the wire. A resin member completely covers at least entire outer surfaces of an exposed region at an end portion of the crimping portion and its vicinal region, and is made from a material mainly containing a thermoplastic polyamide resin, and having a tensile lap-shear strength of lapped aluminums of 6 N/mm2 or more in accordance with the JIS K6850, an elongation of 100% or more in accordance with the ASTM D-1708, and a water absorption of 1.0% or less in accordance with the JIS K7209.

  • Patent number: 8723040
    Abstract: According to the present invention, in a terminal region of a coated wire, a swaged part formed at one end of a terminal fitting is swaged along an outer circumference of a coating part of the coated wire, and the terminal fitting is fixed to a terminal section of the coated wire. A molding resin is formed so as to completely coat the entire outer circumference of an exposed end region (a region including a fracture surface and a base edge) of the swaged part and its adjacent region.

  • Publication number: 20130052887
    Abstract: Disclosed is a terminal structure of a wiring harness for automobile use that has a profound anticorrosive effect. A terminal member is fixed to an end portion of a coated electric wire such that a crimping portion that the member includes at its one end is crimped around an outer surface of a coating portion of the wire. A resin member is formed to completely cover at least entire outer surfaces of an exposed region at an end portion of the crimping portion (a region including a fracture cross section and a root edge portion) and a region in the vicinity thereof. The resin member is made mainly of an epoxy resin, and a cured material obtained by curing a material having a viscosity from 1000 to 30000 mPa·s at 25 degrees C., which is measured in accordance with the JIS Z8803.

  • Publication number: 20120325552
    Abstract: As described above, in the terminal structure for wire harness in this embodiment, since the molding resin 20 is formed to completely coat the entire outer circumference of the exposed end region that becomes the fracture surface 1r of the swaged part 1A and its adjacent region, the possibility that the electrolytic solution enters from the fracture surface 1r (base edge 1e) of the exposed end region, and brass or copper alloy in the swaged part 1A and tin plating on the surface are corroded and finally, a part of the bare wire conductors 11 is corroded can be reliably avoided. Additionally, the possibility that the electrolytic solution entering from the fracture surface 1r finally reaches the bare wire conductors 11 through a gap between the swaged part 1A and coated wire 10 and the bare wire conductors 11 are corroded can be avoided.
