Abstract
The present invention is to provide a crimping terminal. The crimping terminal includes a crimping part, an insertion hole having a bottom provided in the crimping part and projections provided on an inner bottom surface of the insertion hole. When the aluminum electric wire is inserted into the insertion hole, the conductor of aluminum electric wire is relatively rotated against the crimping terminal. As a result, an oxide layer formed on a surface of the conductor is efficiently removed by the projections formed on the inner bottom surface. In low electric resistance condition, the crimping terminal connects with the conductor of the aluminum electric wire.
Claims4
A crimping terminal comprising:
- a crimping part;
- an insertion hole having a bottom provided in the crimping part;
- and
- projections provided on an inner bottom surface of the insertion hole;
- wherein the crimping part is crimped onto a conductor at a tip of an electric wire inserted in the insertion hole so as to electrically connect with the electric wire,
- wherein the conductor abuts against the inner bottom surface of the insertion hole, which surface forms a deepest portion of the insertion hole.
