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.

Claims

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.
