  • Patent number: 7254981
    Abstract: The present invention provides a crimping apparatus that can adapt widely to various diameters of the insulating coatings of wires. The crimping apparatus has a crimp height adjustment mechanism for an insulating coating of a wire, the front of the crimping apparatus facing in a direction opposite to the direction of a core of the wire. The adjustment mechanism includes a shaft member having a regular polygon part and an eccentric shaft part that are connected thereto, and an adjustment dial which is disposed in the eccentric shaft part so as to face in the same direction as the front of the crimping apparatus. Therefore, this crimping apparatus can perform the crimping of terminals having various diameters of the insulating coatings of wires.

  • Publication number: 20050034505
    Abstract: The present invention provides a crimping device that facilitates an adjustment operation and has a reduced height. A crimping device has a crimp height adjustment mechanism for a core of a wire onto which a terminal is to be crimped and a crimp height adjustment mechanism for an insulating coating of the wire, the mechanisms having respective adjustment dials, and the front of the crimping device facing in the opposite direction of the core. In the adjustment mechanisms, the adjustment dials thereof are disposed on the same axis so that the crimping device can have a reduced height compared with conventional crimping devices in which the adjustment mechanisms are disposed at positions different in the vertical direction.
