Abstract

A wire terminal connector is provided that includes a clamping portion that encircles a conductor exposed at an end of an electric wire in a clamping manner. The clamping portion also has a plurality of recesses that are formed on a portion thereof in contact with the conductor. In addition, the wire terminal connector includes a grip portion that encircles a sheath of the electric wire.

First claim

What is claimed is:

1. A wire terminal connector, comprising:
a clamping portion that encircles a conductor exposed at an end of an electric wire in a clamping manner and includes a plurality of recesses formed on a portion thereof in contact with the conductor; and
a grip portion that encircles a sheath of the electric wire,
wherein the plurality of recesses include vertical recesses formed to extend in a direction perpendicular to a direction in which the electric wire extends, and intersecting recesses formed to intersect the vertical recesses.

2. The wire terminal connector according to claim 1 , wherein the intersecting recesses include first intersecting recesses that intersect the vertical recesses at about 75 degrees.

3. The wire terminal connector according to claim 2 , wherein the intersecting recesses include a second intersecting recess that intersect the vertical recesses at about 90 degrees.

4. The wire terminal connector according to claim 3 , wherein the first intersecting recesses are formed on left and right sides with the second intersecting recess interposed therebetween.

5. The wire terminal connector according to claim 4 , wherein the first intersecting recesses and the vertical recesses are connected to form one side of a trapezoid shape.

6. The wire terminal connector according to claim 2 , wherein the clamping portion includes:
an outer side wall portion that forms each vertical recess and is provided as a side wall in a direction of an end portion of the conductor; and
an inner side wall portion that forms each vertical recess, facing the outer side wall portion, and is provided as a side wall in a direction of the sheath,
wherein the outer side wall portion is formed to be sloped.

7. The wire terminal connector according to claim 6 , wherein the outer side wall portion is sloped toward the end portion of the conductor at a tilt angle of about 110 degrees.

8. The wire terminal connector according to claim 7 , wherein the inner side wall portion is formed at about 90 degrees.
