摘要: Device with an electrical contact between an electrical conductor (3) of a flat conductor cable (1) and an electrical connection counterpart (2), where the conductor (3) is embedded in a contact plane (13) in an insulation sheath (4) of the flat conductor cable (1), where the electrical conductor (3) is stripped of the insulation sheath (4) in a predetermined contact section (5) at least on one contact side (7), where the contact section (5) of the conductor is bent out with the contact side (7) from the contact plane (13) to beyond the insulation sheath (4), where the contact side (7) of the contact section (5) of the conductor (3) rests on the electrical connection counterpart (2) and is connected directly to the electrical connection counterpart (2). The invention also relates to a cell connecting system for a vehicle battery module, in particular for an electric or hybrid vehicle. It comprises a contact element for receiving an electrical pole of at least one battery cell, a sensing cable comprising a wire electrically and mechanically connecting a cell monitoring and balancing unit and the contact element. The cell connecting system is characterized in that the surface of the wire and/or the contact element comprises surface area enhancing features in the area of contact with each other. The surface area enhancing features improve the welding process as higher welding forces with more material transfer between the welding parts can be achieved. The invention also relates to a method to manufacture the cell connecting system.

摘要: The present invention relates to a welding method in which a conductor is welded to a workpiece. The conductor comprises a first metal and the workpiece comprises a second metal. At first, an isolation of the conductor is removed at a predetermined length. Subsequently thereto, a bead is formed in a stripped region of the conductor. Subsequently, the conductor is held down on the workpiece wherein a mechanical contact with the welding region between the conductor and the workpiece is formed by the process of holding down. The welding region is in this context arranged in the area of the bead. Subsequently, the conductor is welded to the workpiece in the welding region by means of laser welding.
