  • FIGS. 4A and 4B the pair of crimping pieces 116b are pressed by the wire crimper 120 and the pair of crimping pieces 116b are plastically deformed.
  • the core wire 101 receives a compressive force from the caulking piece portion 116b. Then, as shown in FIG. 4 (b), the core wire 101 extends in the axial direction (a arrow direction, b arrow direction), and a new surface is exposed on each of the strands 101a.

  • the surface of the core wire crimping portion that faces the base portion provides a crimp terminal that is a tapered surface that is inclined in a direction gradually separating from the core wire toward an end in the axial direction of the core wire.
  • the taper surfaces may have a taper boundary at the center of the core wire in the axial direction, and a pair of taper surfaces may be formed from the taper boundary toward both ends.

Also, the core wire extends in the axial direction. For this reason, the elongation of each element wire is greatly increased and adhesion occurs, so that the conduction between the element wires of the core wire can be ensured reliably, and the resistance of the entire circuit can be reduced.

  • the core wire 1 is composed of a large number of strands 1a made of aluminum or aluminum alloy (hereinafter referred to as aluminum), and the numerous strands 1a are twisted together. That is, the electric wire W is an aluminum electric wire.
  • the crimp terminal 10 is made of a copper alloy, and is formed by bending a plate cut into a predetermined shape.
  • the crimp terminal 10 has a mating terminal connection portion 11 and a wire connection portion 15.
  • the electric wire connecting portion 15 includes a core wire crimping portion 16 and an outer skin crimping portion 17.
  • the core wire crimping part 16 has a base part 16a and a pair of caulking piece parts 16b extending from both sides of the base part 16a.
  • a large number of round groove-like serrations 18 are formed on the surface of the base portion 16a with which the core wire 1 contacts, that is, the inner surface. Serrations 18 are not provided on the surfaces of the pair of caulking pieces 16b that contact the core wire 1, that is, the inner surfaces.
  • the inner surfaces of the pair of caulking piece portions 16b are surfaces facing the base portion 16a when the core wire is crimped.
  • the inner surfaces are formed on a pair of tapered surfaces 19 having a taper boundary A at the center in the axial direction C ⁇ b> 1 of the core wire 1.

  • a compressive force acts on the core wire 1 through the core wire crimping portion 16.
  • the core wire 1 extends in the axial direction C1 by this compressive force.
  • the force which presses the core wire 1 to the axial direction C1 acts by the taper surface 19 of a pair of crimping piece part 16b of the core wire crimping part 16, and the core wire 1 is extended to the axial direction C1 also by this pressing force. Specifically, as shown in FIG.
  • the core wire 1 is in the distal direction (a arrow direction) on the distal end side from the taper boundary A of the core wire crimping portion 16, and the rear end from the taper boundary A of the core wire crimping portion 16.
  • the core wire 1 extends to the rear side (the side with the insulating outer skin 2, the direction of arrow b).
  • the wires 1a are greatly stretched compared to the conventional example and adhesion occurs, so that conduction between the wires 1a of the core wire 1 can be reliably ensured, and the resistance of the entire circuit can be reduced.
  • the taper surfaces 19 are formed on both sides with the taper boundary A as the center in the axial direction C1 of the core wire 1. Accordingly, since the core wire crimping portion 16 extends from the center (taper boundary A) to the front end side and the rear end side (side with the insulating outer skin 2) of the core wire 1, it extends substantially uniformly and smoothly, Promotion can be aimed at.
  • Tapered surfaces 19 are formed on the inner surfaces of the pair of caulking pieces 16b. Therefore, since the elongation of each strand 1a of the core wire 1 can be extended symmetrically in the left-right width direction (the orthogonal direction of the axial direction C1 of the core wire 1), the core wire 1 can be crimped with a good left-right balance.
  • a serration 18 is provided on the inner surface of the core wire crimping portion 16. Since the element wire 1a of the core wire 1 is deformed so as to enter the serration 18, that is, is deformed by extension, a new surface is exposed and adhesion occurs, so that the conduction resistance between the core wire 1 and the core wire crimping portion 16 is reduced. At the same time, the conduction resistance between the strands 1a is reduced. This also makes it possible to reduce the electrical resistance at the pressure point with the electric wire W.
  • Core wire 1 is made of aluminum.
  • the aluminum wire 1a has a harder oxide film on the surface than the copper alloy. For this reason, the aluminum core wire 1 has a problem of an increase in electrical resistance due to the conduction resistance between the strands 1a. However, in the present invention, the conduction resistance between the strands 1a can be reduced by the occurrence of adhesion. Effective for aluminum wires.
  • the center in the axial direction C1 of the core wire 1 of the pair of caulking pieces 16b is the taper boundary A, but the position of the taper boundary A may be a position other than the center of the core wire 1 in the axial direction C1.
  • the serration 18 is a groove, but may be a protrusion, or may be both a groove and a protrusion. That is, in this specification, the serration means a groove or a convex portion formed on the surface.
  • the core wire 1 is made of aluminum, but the present invention can also be applied to a core wire 1 other than aluminum (for example, made of copper alloy).
