WIRE CRIMPING DEVICE AND WIRE CRIMPING METHOD

摘要

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.

1. 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 distal 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 crimping means which crimps the crimping section into which the wire tip is inserted from a wire insertion opening which opens on a proximal end side of the crimping section in a terminal axis direction; a guiding means which guides a distal end portion of the conductor to the wire insertion opening of the crimp terminal arranged at a predetermined position for enabling crimping by the crimping means, an inner diameter of an opposedly facing portion of the guiding means which opposedly faces the wire insertion opening being set in conformity with an inner diameter of the wire insertion opening; and a carrier cutting means which is 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 long length direction of the carrier, wherein the carrier cutting means 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 cutting means 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 where the carrier cutting means does not overlap with the wire insertion opening, and the guiding means is disposed at a position in the carrier cutting means which is made to slide to the cutting position, the position corresponding to the wire insertion opening.
