CRIMP TERMINAL, CONNECTION STRUCTURE, AND CONNECTOR

摘要

PROBLEM TO BE SOLVED: To provide a crimp terminal, a connection structure and a connector, by which a crimp condition in which penetration of moisture to the interior of a crimping part can be prevented can be efficiently achieved, in a crimp condition where a conductor portion is crimped by the crimping part.SOLUTION: In a female crimp terminal 10 including a crimping part 30 that permits crimp connection of a covered wire 200 with an aluminum core wire 201, the crimping part 30 is constituted by a plate member that has a cross-sectional hollow shape, a longitudinally-welded portion W1 in the longitudinal direction X is welded, the front of the cross-sectional hollow shape is made to have a substantially flat plate-like sealed shape, and a cross-directionally-welded portion W2 in the cross direction Y is welded.
