Abstract
A crimp terminal includes a core wire crimping portion, an electrical connection portion, and a coupling portion, in which the coupling portion has a bottom wall portion and side wall portions, the side wall portions have straight portions extending from the core wire crimping portion along a longitudinal direction and wide portions connecting between the straight portions and the electrical connection portion, respectively, each of the straight portions extends in a straight line along each of the side walls of the core wire crimping portion, and in a width direction, a distance between the wide portions facing each other is formed so that the distance is gradually wider from the straight portion side toward the electrical connection portion side.
Claims2
A crimp terminal comprising:
- a core wire crimping portion that is configured to be crimped to a core wire exposed from an end of a covering portion of an electric wire;
- an electrical connection portion that is able to be connected to a mating-side member;
- and
- a coupling portion that is provided between the core wire crimping portion and the electrical connection portion, wherein
- the coupling portion includes a bottom wall portion and side wall portions that are provided to stand at both ends of the bottom wall portion respectively in a width direction orthogonal to a longitudinal direction from the core wire crimping portion toward the electrical connection portion,
- each of the side wall portions has a straight portion that extends from the core wire crimping portion along the longitudinal direction and a wide portion that connects between the straight portion and the electrical connection portion,
- the core wire crimping portion includes a bottom wall and side walls that are provided to stand at both ends of the bottom wall respectively in the width direction,
- each of the straight portions extends in a straight line along each of the side walls of the core wire crimping portion,
- in the width direction, a distance between the wide portions facing each other is formed so that the distance is gradually wider from a straight portion side toward an electrical connection portion side, and
- each of the side wall portions includes an upper edge that extends from and is connected to each of the core wire crimping portion and the electrical connection portion, the upper edge at the electrical connection portion is spaced away from the bottom wall portion of the coupling portion in a direction that intersects each of the longitudinal direction and the width direction.

An electric wire assembly comprising:
- an electric wire that is formed of a conductive core wire covered by an insulative covering portion, an end portion of the core wire is exposed from an end of the insulative covering portion;
- and
- a crimp terminal that includes a core wire crimping portion crimped onto the end portion of the core wire, an electrical connection portion provided on an opposite side to a covering portion side with respect to the core wire crimping portion and configured to be connected to a mating-side member, and a coupling portion provided between the core wire crimping portion and the electrical connection portion, wherein
- when the crimp terminal is crimped onto the end portion of the core wire, a height of the crimp terminal at a first end portion on a coupling portion side in the core wire crimping portion is lower than a height of the crimp terminal at a second end portion on the covering portion side in the core wire crimping portion,
- the coupling portion includes a bottom wall portion and side wall portions that are provided to stand at both ends of the bottom wall portion respectively in a width direction of the crimp terminal,
- each of the side wall portions has a straight portion that extends from the core wire crimping portion toward the longitudinal direction of the crimp terminal and a wide portion that connects between the straight portion and the electrical connection portion,
- each of the straight portions extends in a straight line along each of side walls of the core wire crimping portion, and
- in the width direction of the crimp terminal, a distance between the wide portions facing each other is formed so that the distance is gradually wider from a straight portion side toward an electrical connection portion side, and
- each of the side wall portions includes an upper edge that extends from and is connected to each of the core wire crimping portion and the electrical connection portion, the upper edge at the electrical connection portion is spaced away from the bottom wall portion of the coupling portion in a direction that intersects each of the longitudinal direction and the width direction.
