Terminal crimping structure and terminal crimping method onto aluminum electric-wire and producing method of aluminum electric-wire with terminal

摘要

A terminal crimping structure onto aluminum electric-wire, for crimping a terminal 101 onto an aluminum electric-wire 140 including: an electrical conductor part comprising numerous strands; and a coating part coated on the electrical conductor part; wherein the terminal 101 has a wire barrel 121 to be crimped onto the electrical conductor part of the aluminum electric-wire; and wherein the compressed ratio of the aluminum electric-wire's conductor part 141 by the wire barrel 121 is within a range of 50 to 70%, in terms of the ratio of (cross-sectional area of aluminum electric-wire's conductor part at crimped portion)/(cross-sectional area of aluminum electric-wire's conductor part before crimping).
