ABSTRACT:
A crimping terminal joined with an aluminum electric wire, in which when the crimping terminal is crimped to the wire, a conduct-purpose crimping portion and a wire-hold crimping portion are formed at a crimping portion of a wire barrel of the crimping terminal. The crimping portion of the wire barrel is formed so as a curvature thereof is projected upwardly in a direction of moving a crimping die and so as a crimp height increases and a compression ratio decreases towards an insulation barrel of the crimping terminal. The curvature is shaped to have a constant degree of curvature, and is shaped to form a quadratic curve as a result of strictly adjusting a crimping force.
