Abstract
An electrical contact crimp ear serration comprised of a plurality of teeth where each tooth has a cross-sectional profile comprising a leading face extending upwardly to an apex from the crimp ear surface, a central face extending downwardly from the apex to a valley below the crimp ear surface, and a trailing face extending upwardly from the valley to the crimp ear.
Claims4
A serration for an electrical contact crimp ear having a nominal surface with a flat surface, said serration comprised of a plurality of teeth, each of said teeth having a cross-sectional profile comprising:
- (a) a leading face extending upwardly from said nominal surface to a rounded apex at an average angle of between approximately 18° and 28° to said nominal surface, said apex having a height from said nominal surface;
- (b) a central face extending downwardly from said apex and past said nominal surface to a valley at an average angle of between approximately 82° and 90° to said nominal surface, said valley having a depth from said nominal surface that is greater than said apex height;
- and
- (c) a trailing face extending upwardly from said valley to said nominal surface at an average angle of between approximately 12° and 18° to said nominal surface.
