Abstract

A slip ring assembly for the electrical connection of two rotating parts has at least a sliding track with V-grooves. At least two brushes of electrically conductive material are contacting the sliding track within the V-groove. The brushes are connected electrically with each other and mounted at different levels resulting in a different distance to the rotation axis of the sliding track. This results in an improved resistance against shock and vibrations.
