  • Patent number: 10818408
    Abstract: An insulated wire has a conductor, and an insulating film including a first insulating layer covering the conductor and a second insulating layer covering the first insulating layer. The second insulating layer contains a polyimide or a polyamideimide as a main component. The first insulating layer contains a reaction product of a carboxylic acid dianhydride and a diamine as an adhesive component and a component that is the same as the main component in the second insulating layer. At least one of the carboxylic acid dianhydride and the diamine has a carbonyl group.

  • Patent number: 8815440
    Abstract: A battery cover member (10) of the present invention includes a metallic electrode terminal (40), a metallic cover member (30) having through holes (32), and an insulating resin member (50), in which the electrode terminals inserted into the through hole and the cover member are integrally bonded together by the insulating member, wherein at least a sealing area (70) of the electrode terminal that adheres to the insulating member is formed as a columnar shape or an elliptically columnar shape.

  • Patent number: 8748035
    Abstract: An object is to provide a battery with good durability, and a vehicle and a battery-mounting device each having such a battery mounted therein. A battery includes a positive electrode terminal member made of aluminum, a negative electrode terminal member made of copper, a positive electrode resin member made of an insulating resin, covering a part of the terminal member in tight contact therewith, and a negative resin member made of an insulating resin, covering a part of the terminal member in tight contact therewith. A positive electrode resin adhesion surface and a negative electrode resin adhesion surface each have been subjected to a surface treatment. A negative electrode sealing length of a shortest path of negative seal paths is longer than a positive electrode sealing length of a shortest path of positive electrode seal paths.

  • Publication number: 20120038365
    Abstract: In a liquid leakage propagation restraining structure, a voltage detection terminal that detects the voltage of an electricity storage device is connected to an electrode of the electricity storage device so that a crimp contact surface side of the voltage detection terminal to which an electric cable is crimped faces in the direction opposite the direction to the electrode. Therefore, the structure restrains the electrolytic solution that has leaked out and propagated to the electric cable from entering the interior of the core wire of the electric cable.
