Arrangement of a contact element on free coil conductor ends of an electric machine, electric machine for a motor vehicle, method for providing a contact element for an electric machine, and motor vehicle

An arrangement comprising:

• a contact element on free coil conductor ends of an electric machine, wherein:
• at least one coil conductor end is inserted into an insertion opening of an assigned contact sleeve of the contact element and is welded to the assigned contact sleeve,
• the contact element is configured to interconnect at least two coil conductor ends in an electrically conductive manner,
• the at least one coil conductor end bears over its entire circumference, in a longitudinal region of a direction of insertion of the at least one coil conductor end into the assigned contact sleeve, against an inside of a wall that delimits the insertion opening of the assigned contact sleeve,
• the at least one coil conductor end has a first taper that is formed by a pyramid vertex of its free end, and
• the insertion opening has a second taper in the direction of insertion.
