▎ 摘  要

NOVELTY - The crimp connection (1) has a conductor (2) that is provided with one end (5) which is embedded in a solder (6). A connection element (4) is connected to the end of the conductor embedded in the solder by crimping. The conductor is formed on the basis of a carbon conductor (10) which is formed from carbon nanotubes or graphene. The connection element is provided with a sleeve element (7) which encloses the end of the conductor embedded in the solder. The sleeve element is provided with an embossing (8) on which the sleeve element is pressed into the end of the conductor embedded in the solder. The connection conductor is formed on the basis of a copper cable. USE - Crimp connection for connecting electrical conductor such as stator winding of electric motor (claimed) such as drive motor of motor vehicle to connection element. ADVANTAGE - The strength of the connection is increased by the additional connecting element or sleeve element with an uniform surface load on the entire soldering point. The high mechanical stability and protection for the connection are achieved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an electric motor for motor vehicle. DESCRIPTION OF DRAWING(S) - The drawings show the cross-sectional view of the crimp connection for a stator winding of an electric motor, side view of the crimp connection and electric motor, and side view of the crimp connection. 1Crimp connection 2Conductor 4Connection element 5End of conductor 6Solder 7Sleeve element 8Embossing 10Carbon conductor
