COATED ELECTRIC WIRE, CONNECTION STRUCTURE, WIRE HARNESS, CONNECTOR, AND MANUFACTURING METHOD OF COATED ELECTRIC WIRE AND CONNECTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a coated electric wire, a connection structure, and a wire harness which are capable of reliably preventing infiltration of moisture from an insulating coating side, and a manufacturing method of a coated electric wire, a connector, and a connection structure.SOLUTION: In the state where a crimp part 322 in a crimp terminal 300 and a coating tip part 220T closer to a tip of an insulating coating 220 are crimped by a pair of crimping blade dies 600, areas corresponding to boundaries between crimping surfaces 610 of each crimping blade die 600 are set as areas 400Z corresponding to crimping surface boundaries in a circumferential direction of the coating tip part 220T, and an elastic protrusion 221 which protrudes so as to be elastically deformed associated with compression of the crimp part 322 is included at least in the areas 400Z corresponding to crimping surface boundaries in the circumferential direction of the coating tip part 220T.
