Abstract:
1. A crimping terminal joined with an aluminum electric wire including a conductive core portion formed by a plurality of twisted core wires and a covered portion covering the conductive core portion, comprising: an insulation barrel crimped with the covered portion; a wire barrel crimped with the conductive core portion exposed by removing a predetermined length of the covered portion from an end of the aluminum electric wire; and a crimping portion formed at the wire barrel when the wire barrel is crimped to the conductive core portion of the aluminum electric wire, so as to form a conduct-purpose crimping portion and a wire-hold crimping portion at the crimping portion, wherein the entire crimping portion of the wire barrel has a continuous curved shape, or each of the conduct-purpose crimping portion and the wire-hold crimping portion of the wire barrel has a curved shape which is continuous, the curved shape projecting upwardly or downwardly in a direction of moving a crimping die when viewing in a direction perpendicular both to the direction of moving the crimping die and a direction along a lengthwise of the aluminum electric wire so as to increase a crimp height toward the insulation barrel, thereby strictly adjusting a crimping force at the crimping portion.
