Electrically-conducting contact element with an aperture with an internal surface having a groove with sharp edges

摘要

An electrically-conducting contact element includes a section of the contact element defining an aperture. The section is configured to receive a wire cable within the aperture for attachment thereto. The section includes an internal surface with at least one groove having sharp edges formed therein. A wire assembly that includes the electrically-conducting contact and a method to construct the electrically-conducting contact are also presented. The method includes a step of providing the contact element and forming at least one cutout groove on the internal surface of the contact element. A further step in the method includes altering material on the internal surface of the contact element by a forming means. The forming means may be one of milling, rifling, machining, cutting, indenting, or stamping. A wire assembly and a vehicular electrical wiring harness that respectively include the contact element are also further presented.
