Patent ID: 8337262

Claim:
A terminal connector including a crimping portion configured to be crimped onto a core wire exposed from an electric wire in a binding manner, the electric wire including the core wire including aluminium or aluminium alloy, the terminal connecter comprising: in a state where the crimping portion is crimped onto the core wire, the crimping portion has a surface to be applied to the core wire, the surface having a plurality of recesses formed therein, each recess having a parallelogram-shaped opening edge, the opening edge of the recess including a pair of first opening edges and a pair of second opening edges, the first opening edges being parallel to each other, the second opening edges being parallel to each other and differing from the first opening edges, the recesses being spaced in an extending direction of the first opening edges and being spaced in an extending direction of the second opening edges; the first opening edge has an angle from 85 deg. to 95 deg. to the extending direction of the electric wire, and the second opening edge has an angle from 25 deg. to 35 deg. to the extending direction of the electric wire; and the opening edge and a bottom surface of each recess are connected by four inclined surfaces, the inclined surfaces having a pair of first inclined surfaces and a pair of second inclined surfaces, the first inclined surfaces connecting the respective first opening edges with the bottom surface of each recesses, each first inclined surface having an angle from 90 deg. to 110 deg. to a surface that is a part of the surface of the crimping portion to be applied to the core wire, the part having none of the recesses formed therein, the second inclined surfaces connecting the respective second opening edges with the bottom surface of each recesses, and each second inclined surface having an angle from 115 deg. to 140 deg. to the surface that is the part of the surface of the crimping portion to be applied to the core wire, the part having none of the recess formed therein.
