Abstract

A crimping terminal comprises: a conductor crimping portion including a bottom plate and a pair of conductor crimping tabs, the conductor crimping tabs being extending from both sides of the bottom plate in a widthwise direction perpendicular to a lengthwise direction of the crimping terminal and being configured to crimp a conductor of an electrical cable so as to wrap the conductor, the conductor being formed by a bundle of wires and serving as a crimping subject disposed on the bottom plate along the lengthwise direction, the inner surface of the conductor crimping portion being provided with serrations including a plurality of uniformly cylindrical recesses with a diameter smaller than the diameter of the wire of the conductor, and wherein, in the plurality of recesses, the adjacent recesses deviated from each other in the widthwise direction of the crimping terminal partly overlap each other when seen from the lengthwise direction.

Claims

1. A crimping terminal comprising:

a conductor crimping portion including a bottom plate and a pair of conductor crimping tabs, the conductor crimping tabs being formed extending from both sides of the bottom plate in a widthwise direction perpendicular to a lengthwise direction of the crimping terminal and being configured to crimp a conductor of an electrical cable so as to wrap the conductor, the conductor being formed by a bundle of wires and serving as a crimping subject disposed on the bottom plate along the lengthwise direction, the inner surface of the conductor crimping portion being provided with serrations including a plurality of uniformly cylindrical recesses with a diameter smaller than the diameter of the wire of the conductor, and

wherein, in the plurality of recesses, the adjacent recesses deviated from each other in the widthwise direction of the crimping terminal partly overlap each other when seen from the lengthwise direction.

2. The crimping terminal according to claim 1,

wherein when it is assumed that a grid is formed so as to obliquely intersect with the lengthwise direction of the crimping terminal, the recesses are disposed at grid points of the grid, and

the recesses are arrayed in the lengthwise direction of the crimping terminal while being staggered in the widthwise direction of the crimping terminal.

3. The crimping terminal according to claim 2,

wherein the recesses of the serration are arrayed in the lengthwise direction of the crimping terminal with being staggered by a half of a pitch in the width direction thereof, and the pitch is a distance with respect to adjacent one of the recesses arranged in the width direction of the crimping terminal.

4. The crimping terminal according to claim 3,

wherein the grid includes a quadrilateral unit frame with a first diagonal line along the lengthwise direction of the crimping terminal and a second diagonal line perpendicular to the first diagonal line, and

the first diagonal line is longer than the second diagonal line.

5. The crimping terminal according to claim 3,

wherein the grid includes a quadrilateral unit frame with a first diagonal line along the lengthwise direction of the crimping terminal and a second diagonal line perpendicular to the first diagonal line, and

the length of the first diagonal line is equal to the length of the second diagonal line.
