Abstract
A semi-finished product for manufacturing an electrical contact element includes a first workpiece having a front side and a rear side opposite the front side, a second workpiece, and a window extending through the first workpiece. The first workpiece and the second workpiece are both metallic. The rear side of the first workpiece is closer to the second workpiece than the front side. Through the window, a surface of the second workpiece is accessible from the first workpiece. The window has a base area that, starting at the front side of the first workpiece, increases toward the second workpiece.
Claims19
A semi-finished product for manufacturing an electrical contact element, comprising:
- a first workpiece having a front side and a rear side opposite the front side;
- a second workpiece, the first workpiece and the second workpiece are both metallic, the rear side of the first workpiece is closer to the second workpiece than the front side;
- and
- a window extending through the first workpiece and through which a surface of the second workpiece is accessible from the first workpiece, the window has a base area that, starting at the front side of the first workpiece, increases toward the second workpiece, the surface of the second workpiece that is accessible through the window is within an undercut formed in the second workpiece.
An electrical contact element, comprising:
- a semi-finished product including:
- a first workpiece having a front side and a rear side opposite the front side;
- a second workpiece, the first workpiece and the second workpiece are both metallic, the rear side of the first workpiece is closer to the second workpiece than the front side;
- and
