CONNECTION-STRUCTURE MANUFACTURING METHOD, WIRE HARNESS, AND CONNECTION-STRUCTURE MANUFACTURING DEVICE

摘要

The purpose of the present invention is to provide the following: a connection-structure manufacturing method whereby a connection structure (1) in which an aluminum core (101) is firmly crimped by a closed-barrel crimp section (230), yielding stable conductivity, is manufactured efficiently; a wire harness (2); and a device (10) for manufacturing the aforementioned connection structure (1). This method and device (10) are used to manufacture connection structures (1), each of which crimps together and connects the following: a coated wire (100) provided with a wire tip section (103) where an insulating coating (102) has been stripped from the tip of the coated wire (100); and a crimp terminal (200) provided with a closed-barrel crimp section (230) that allows the wire tip section (103) to be crimp-connected. The following steps are performed, in this order: a carrier cutting step in which crimp terminals (200) are separated from a terminal attachment strip (300) comprising a plurality of crimp terminals (200) attached to a carrier (250) in a lengthwise direction; a wire insertion step in which wire tip sections (103) are inserted into the crimp sections (230) of the separated crimp terminals (200); and a crimping step in which the crimp sections (230) into which wire tip sections (103) have been inserted are crimped so as to crimp-connect same.
