Abstract
A wire crimping device includes: a wire crimping unit which crimps a crimping section into which a wire tip is inserted from a wire insertion opening which opens on a proximal end side of the crimping section in a long length direction; and a guiding unit which guides a distal end portion of an aluminum lead line to the wire insertion opening of a female crimp terminal arranged at a predetermined position for being crimped by the wire crimping unit, wherein an inner diameter of an opposedly facing portion of the guiding unit which opposedly faces the wire insertion opening is set in conformity with an inner diameter of the wire insertion opening.
Claims7
A wire crimping device by which an insulated wire formed by covering a conductor with an insulating cover and provided with a wire tip formed by exposing the conductor by peeling off the insulating cover on a first end side, and a closed-barrel-type crimp terminal provided with a hollow crimping section which allows the crimping connection of the wire tip are connected to each other by crimping the crimping section and the wire tip to each other, the wire crimping device comprising:
- a crimper configured to crimp the crimping section into which the wire tip is inserted from a wire insertion opening which opens on a second end side of the crimping section in a terminal axis direction, the second end side being different from the first end side;
- a guide configured to guide an end portion of the conductor to the wire insertion opening of the crimp terminal arranged at a predetermined position for enabling crimping by the crimper, an inner diameter of an opposedly-facing portion of the guide, which is opposite to the wire insertion opening corresponding to an inner diameter of the wire insertion opening;
- and
- a carrier cutter configured to separate a plurality of crimp terminals from a carrier of a terminal connection strip, the carrier formed in a strip-shape, the terminal connection strip formed by connecting the plurality of crimp terminals to the carrier via connecting portions at predetermined intervals in a longest length direction of the carrier,
- wherein the carrier cutter is configured to shear the connecting portions in a thickness direction of the carrier by sliding in the thickness direction of the carrier from a stand-by position where the carrier cutter overlaps with the wire insertion opening to a cutting position which is disposed on a side opposite to a side where the crimping section is arranged with respect to the carrier, the cutting position being a position where the carrier cutter does not overlap with the wire insertion opening, and the guide is disposed at a position in the carrier cutter, which is made to slide to the cutting position, which corresponds to the wire insertion opening, in the cutting position.

- a crimper including:
- a conductor-crimping section configured to crimp a conductor exposed portion of the wire tip;
- and
- a cover-crimping section configured to crimp an insulated cover portion of the wire tip at a portion closer to a second end side than the conductor-crimping section, and to crimp the crimping section of the crimp terminal into which the wire tip is inserted from a wire insertion opening which opens on a third end side of the cover crimping section in a terminal axis direction;
- a guide configured to guide a first end side portion of the conductor to the wire insertion opening of the crimp terminal arranged at a predetermined position to enable crimping by the crimper;
- and
- a carrier cutter configured to separate a plurality of crimp terminals from a carrier of a terminal connection strip, the carrier formed in a strip-shape, the terminal connection strip formed by connecting the plurality of crimp terminals to the carrier via connecting portions at predetermined intervals in a longest length direction of the carrier,
