TERMINAL, WIRE CONNECTION STRUCTURE, AND METHOD FOR MANUFACTURING TERMINAL

摘要

It is an object of the present disclosure to provide a terminal that can improve adhesion between a tubular crimp portion and an electric wire and reliability can be maintained for a long term. A terminal (40) includes a connector portion (10) electrically connectable to an external terminal (2); and a tubular crimp portion (30) that is provided via the connector portion (10) and a transition portion (20) and crimped with an electric wire (3). The tubular crimp portion has a belt-shaped weld portion formed along a direction that is substantially the same as a longitudinal direction of the tubular crimp portion (30), and a circumferential direction of the tubular crimp portion (30) is substantially the same as a RD-direction of the base material forming the tubular crimp portion (30). A sum of area ratios (R1, R2, R3) of crystal grains oriented in Cube orientation {001}<100>, RDW orientation {120}<001>, and Goss orientation {110}<001> is greater than or equal to 15%, where R1, R2 and R3 that are facing a (100) plane of a centered cubic lattice with respect to direction RD-direction.
