CONNECTION STRUCTURE, TERMINAL CRIMP MEMBER, WIRE HARNESS, CONNECTOR, CRIMPING METHOD OF CONNECTION STRUCTURE AND CRIMPING DEVICE FOR CRIMPING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a connection structure capable of crimping and connecting a crimp part of a crimp terminal to a wire distal end portion of a covered conductor so as to be a desired crimp shape without deforming the crimp part into a non-intended crimp shape, a terminal crimp member, a wire harness, a connector, a crimping method of the connection structure and a crimping device for crimping the same.SOLUTION: When crimping a conductor crimp portion 30a in a crimp part 30 of a female crimp terminal 10 to a wire distal end portion 200a of a covered conductor 200, outer peripheral contact parts 613 and 613 of a lower die 61 in a crimping device 60A and an outer peripheral contact part 623 of an upper die 62 are point-contacted in bilateral symmetry with a reference plane formed from a length direction X and a crimp direction Z as a reference to an outer periphery of the conductor crimp portion 30a on an orthogonal cross section in a direction orthogonal with the length direction X and the crimp direction Z. When crimping the conductor crimp portion 30a, without revolving or twisting it, the conductor crimp portion 30a can be crimped and connected to a conductor distal end portion 201a of an aluminum core wire 201 while being deformed into a desired crimp shape.
