  • 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.

  • Publication number: 20130062114
    Abstract: An anticorrosive that is capable of demonstrating high anticorrosive capability. The anticorrosive mainly contains at least one of a photopolymerizable (meth)acrylate monomer and a photopolymerizable (meth)acrylate oligomer, and has a viscosity of 1000 mPa·s or more to less than 20000 mPa·s at 25 degrees C., which is measured in accordance with the JIS Z8803. The anticorrosive can be favorably applied to an electrically connected portion between a wire conductor of a coated electric wire with a terminal and a terminal member. The coated electric wire with the terminal includes the wire conductor and the terminal member, wherein the electrically connected portion between the wire conductor and the terminal member is coated with the anticorrosive that is cured.
