Electrical contact device and electrical welded connection and method for producing a contact device and for establishing a welded connection

摘要

The invention relates to an electrical contact device (10), in particular a compacted section (10) of an electrical connector (1), preferably an electrical line (1), for use in the medium or high current range, wherein the contact device (10) in a first approximation a comparatively large cross-section (Q10) with a comparatively large cross-sectional dimension (Qab10) for a flow of an electrical current, and the contact device (10) a shaping area (100), in particular a forming area (100), with a comparatively small cross-sectional dimension (Qab100) has, over which the contact device (10) to an electrical mating connector (3) is weldable and / or welded.
