Abstract

In a conductor crimping portion 3, a pair of crimping pieces 3c and 3d having a two-layer structure of an upper layer plate 3a and a lower layer plate 3b connecting the upper layer plate 3a is raised in a U-shape from both sides of a bottom portion 3e. A void 3g is formed inside a folded-back portion of the upper layer plate 3a from the lower layer plate 3b. In the conductor crimping portion 3, the crimping pieces 3c and 3d have a two-layer structure, and a conductor portion is elastically fixed and connection becomes strong due to the presence of the void 3g.

Claims

1. A crimp connection terminal formed by punching and bending one conductive metal plate to caulk and fix an electric wire,

wherein a connection portion connected to a connection terminal of a counterpart connecter is disposed at a front side, a conductor crimping portion to crimp and fix a conductor portion of the electric wire is disposed at a rear side, the conductor crimping portion has a pair of crimping pieces raised in a U-shape from a bottom portion,

the crimping pieces of the conductor crimping portion have a lower layer plate and an upper layer plate formed by folding back from an end portion of the lower layer plate and stacking on the lower layer plate, and a void is formed inside the folded-back portion between the lower layer plate and the upper layer plate.

2. The crimp connection terminal according to claim 1, wherein the void has a shape of a water droplet.

3. The crimp connection terminal according to claim 1, wherein the electric wire is a fiber wire.

4. The crimp connection terminal according to claim 2, wherein the electric wire is a fiber wire.

5. The crimp connection terminal according to claim 1, wherein a gap is provided in a butted portion of end edges of the upper layer plate on the lower layer plate.

6. The crimp connection terminal according to claim 2, wherein a gap is provided in a butted portion of end edges of the upper layer plate on the lower layer plate.

7. The crimp connection terminal according to claim 1, wherein a gap is provided in a butted portion of the upper layer plate in the conductor crimping portion.
