Patent ID: 8177589

Claim:
A terminal connector comprising: a crimping portion that is crimped onto a conductor exposed at an end of an electric wire so as to surround the exposed conductor, wherein a plurality of recesses are formed on a surface of the crimping portion where the electric wire is provided, and the recesses are arranged with a distance therebetween in an extending direction in which the electric wire that is crimped onto the crimping portion extends, and in a state before the crimping portion is crimped onto the electric wire, the recesses are formed to be arranged in a crossing direction crossing to the extending direction with a distance therebetween, wherein in a state before the crimping portion is crimped onto the electric wire, rims of an opening of each recess form a quadrangular shape and at least one of sides comprising the rims of the opening of each recess is a crossing side that crosses at an angle ranging from 85 degrees to 95 degrees to the extending direction, and wherein in a state before the crimping portion is crimped onto the electric wire, a length of the crossing side is set to be equal to or greater than a distance between the facing terminal ends of the crossing sides of the recesses that are arranged adjacent to each other in the crossing direction, and the crossing sides of the recesses that are arranged adjacent to each other in the extending direction are arranged to overlap with each other in the extending direction so that the crossing sides are present over the entire length of all of the plurality of recesses on the crimping portion in the crossing direction.
