Patent number: 9601839Abstract: A crimping terminal includes a conductor crimping portion having a U-shaped cross section. The conductor crimping portion includes a base plate portion and a pair of conductor caulking pieces. On an inner surface of the conductor crimping portion, a conductor is disposed, being exposed to a distal end of an aluminum electric wire. The pair of conductor caulking pieces, extending upwardly from both side edges in a longitudinal direction of the base plate portion, are bent inwardly so as to wrap the conductor of the aluminum electric wire to caulk the conductor such that the conductor is in close contact with the inner surface of the base plate portion. On the inner surface of the conductor crimping portion, a protruding indent is provided so as to extend continuously.Type: GrantFiled: September 17, 2015Date of Patent: March 21, 2017Assignee: YAZAKI CORPORATIONInventor: Tadahisa Sakaguchi
