1. A crimp terminal comprising:
a conductor crimp portion having a cross section formed into a U-shape by a bottom plate and a pair of conductor crimp pieces provided to extend on both sides of the bottom plate and crimped to wrap a conductor of an electric wire disposed on an inner surface of the bottom plate; an electrical connection portion provided at a front end of the conductor crimp portion and being electrically connectable to a mating terminal; and a coated crimp portion provided at a rear end of the conductor crimp portion and configured to crimp a coated portion of the electric wire, wherein the conductor crimp portion is crimped and connected to the conductor and includes serrations at respective lattice points of a lattice assumed in an inner surface of the conductor crimp portion and obliquely crossing in a longitudinal direction of the conductor, the serrations being consisted of cylindrical recesses having the same shape, wherein a first diagonal line of the lattice is located along the longitudinal direction of the conductor, wherein a second diagonal line of the lattice is located perpendicular to the longitudinal direction of the conductor, wherein the conductor crimp portion includes a front end side crimp portion on a side of the electrical connection portion and a rear end side crimp portion on a side of the coated crimp portion, wherein the serrations include first serrations having a length of the first diagonal line greater than a length of the second diagonal line, and second serrations having a length of the first diagonal line smaller than a length of the second diagonal line, wherein the first serrations are disposed in the rear end side crimp portion, and wherein the second serrations are disposed in the front end side crimp portion. |
