Abstract (en)
A slip ring module (10) comprises a body (11) holding a plurality of sliding tracks (12). The sliding tracks have a T-shaped cross-section with a support portion (15) and a contact portion (13) further providing a contact surface (14). A slip ring brush, which may be a wire brush or carbon brush, is sliding on the contact surface to provide contact to the slip ring module which may rotate against the brush. The contact portion is wider than the support portion, resulting in an enlarged creepage distance (40) at the surface of the body. This further results in an increased isolation and life time of the slip ring module.
