A crimp terminal has a crimp barrel which is crimped onto a core wire of a cable. The crimp barrel has an inner surface in which a plurality of cavities which are independent from one another is formed. Each of the cavities has a predetermined shape in a plane orthogonal to a depth direction thereof before the crimp barrel is crimped onto a core wire. The predetermined shape has at least two straight portions and a concave curved portion connecting the straight portions. The concave curved portion is indented inward of the predetermined shape. A plurality of the concave curved portions which are close to each other and included respectively in the predetermined shapes distinct from each other is arranged on an identical imaginary circle or rounded rectangular.

Crimp terminal and connector

Gripping surface for crimping terminal part

A crimp terminal includes a crimp barrel to be crimped around a conductive core of a cable. The crimp barrel includes an inner surface which is formed with a plurality of cavities independent of one another. Each of the cavities has a predetermined shape in a plane perpendicular to a depth direction of the cavity. The predetermined shape contains a plurality of straight-line segments. Every one of the straight-line segments of the predetermined shape is not parallel with remaining ones of the straight-line segments of the predetermined shape. The straight-line segments of the predetermined shape includes at least one pair of the straight-line segments, which are closest to each other among the straight-line segments of the predetermined shape and are arranged to make an interior angle less than 90 degrees or, if not intersecting each other, are arranged on two straight lines, respectively, wherein the two straight lines make an interior angle less than 90 degrees.
