Abstract
The invention provides an electrical connection for an electric motor having a casing which houses a drive device, embodied especially a stator in a casing interior. The drive device is contacted via a conductor, embodied especially in the form of a pin. The conductor is guided from the exterior into the interior of the casing via a casing opening. A cylindrical sealing element is provided on the casing opening in the casing interior to seal the conductor from the casing opening. The sealing element is provided with a continuous collar and a through-opening through which the conductor extends and in which the conductor is sealed in the through-opening via at least one radial sealing lip that is formed in the through-opening on the sealing element and that rests on a surface of the conductor. The conductor is then sealed towards the housing via at least one axial sealing lip that is formed on the collar and that rests on an inside of the casing. The electrical connection according to the invention can be used for a motor, especially for driving a motor cooling fan.
