CRIMP TERMINAL, CONNECTION STRUCTURE, CONNECTOR, AND METHOD OF MANUFACTURING CONNECTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a crimp terminal which allows for enhancement of work efficiency by facilitating insertion of a coated wire into the insertion hole of the crimp terminal, and enhancement of water-stopping and conductivity by reliable crimping of the crimp part of a crimp terminal and the conductor exposed part of a coated wire, and to provide a connection structure, a connector, and a method of manufacturing a connection structure.SOLUTION: A crimp terminal 100 includes a crimp part 120 which allows for crimp connection of a conductor exposed part 220 where the conductor 222 is exposed by stripping a predetermined length of an insulation coating 210 on the tip side Xa in a coated wire 200 produced by coating the conductor 222 with the insulation coating 210. The crimp part 120 is constituted to have a hollow cross-section, and the tip side Xa of a base end Xb in the longitudinal direction X of the crimp part 120 is set in the crimp part main body 122. A base end side enlarged diameter portion 123 having an inside diameter larger than that of the crimp part main body 122 is formed at at least the base end of the crimp part 120 in the longitudinal direction X.
