METHOD OF MANUFACTURING CONNECTION STRUCTURE, WIRE HARNESS, AND DEVICE FOR MANUFACTURING CONNECTION STRUCTURE

摘要

To provide a method and a device for manufacturing a connection structure (1) and a wire harness (2). The connection structure connects an insulated wire (100) comprising a wire tip portion (103), an insulating covering (102) being stripped from the tip thereof, to a crimp terminal (200) comprising a closed-barrel-type crimping portion (230) allowing crimp connection with the wire tip portion (103) and has stable conductivity by crimping an aluminum core wire (101) by the crimping portion (230). The method comprises a carrier cutting step for separating crimp terminals (200) from a terminal connecting belt (300) comprising the crimp terminals (200) attached to a carrier (250) in a longitudinal direction, a wire insertion step for inserting wire tip portions (103) into the crimping portions (230) of the separated crimp terminals (200), and a crimping step for crimping the crimping portions (230) with the inserted wire tip portions (103).

主权项

1. A method of manufacturing a connection structure, the connection structure connecting
an insulated wire including a conductor covered by an insulating covering and an electric wire tip portion exposing the conductor on a tip side by the insulating covering being stripped from the tip side, to a crimp terminal including a closed-barrel type crimping portion allowing a crimp connection with the electric wire tip portion, by crimping the electric wire tip portion using the crimping portion, the method comprising, in the following order: a carrier cutting step in which the crimp terminal is separated from a terminal connecting belt, the terminal connecting belt comprising the crimp terminal being coupled to a carrier formed in a band shape along a latitudinal direction of the carrier and a plurality of the crimp terminals being coupled to the carrier at predetermined intervals in a longitudinal direction of the carrier; a wire insertion step in which at least the electric wire tip portion of the insulated wire is inserted into the crimping portion of the crimp terminal separated from the carrier; and a crimping step in which a crimp connection is formed by crimping the crimping portion into which the electric wire tip portion has been inserted, the crimping portion of the crimp terminal being held by holding means in the carrier cutting step; and as the holding means, in the crimping step, the crimping portion is held by crimping means that crimp the crimping portion.
