  • Publication number: 20020114994
    Abstract: In a terminal structure wherein the led-out plate portion of a plate terminal one end plate portion of which is connected to an electrode pole jutting out of the cover of a storage battery is fixed onto the top face of the cover, when external lead wire is clamped to the plate terminal by a bolt and a nut, the plate terminal is liable to incline, turn, twist, deform or float due to a large clamping torque. A terminal structure of a storage battery as prevents such drawbacks from occurring and as is stable and stout against the clamping torque, is provided.

  • Patent number: 6392148
    Abstract: The present invention provides a wire harness joint including a wiring circuit assembly and an insulation film or insulation films applied to the wiring circuit assembly, either on one or both sides. The wiring circuit assembly includes a number of flexible flat cables (FFC) disposed separately so that each one will not intersect another. The wiring circuit assembly further includes connections for connecting the tips of a wire harness that includes a plurality of parallel disposed FFCs to the FFCs of the wiring circuit assembly. Each of the insulation films is formed with windows at positions corresponding to the connections.
