Abstract
The present invention relates to a method for producing an electric contact element from a semifinished product and to the electric contact element and the corresponding semifinished product. The method for producing an electric contact element (), which can be electrically contacted by a mating contact, comprises the following steps: producing a wire () from a first electrically conductive material (); coating the wire surface with a sheath () made of a second electrically conductive material; partially removing the sheath () in a direction along a longitudinal wire axis (); forming at least one cylindrical semifinished product () by dividing the wire in a direction transverse to the longitudinal wire axis; fixing the semifinished product on a contact carrier () such that the second electrically conductive material is connected to the contact carrier; and reshaping the welded semifinished product so as to form the contact element (), wherein a contact area (), which is accessible for a mating contact, is formed by the first electrically conductive material.
