A slip-ring brush includes a holder and a brush element that has three regions. The brush element is joined in the first region to the holder, and exhibits a cross-sectional geometry having a cross-sectional area in the second region, which is predetermined for the contacting with a slip ring. The brush element has the same cross-sectional area in the third region as in the second region. The brush element is additionally arranged such that its third region is disposed between the first region and the second region. The cross-sectional geometry of the brush element in the third region is shaped so that it deviates from the cross-sectional geometry of the second region, to reduce the effective spring stiffness of the brush element.

Slip-ring brush and slip-ring unit equipped with such a slip-ring brush

A method for manufacturing a slip-ring element having contact rings includes the following steps: machining and/or coating lateral sides of the contact rings; mounting the individual contact rings side-by-side, so that they touch each other at the end face; at least partially filling the inner space formed by the side-by-side-mounted contact rings with an adhesive agent, so that the side-by-side-mounted contact rings are cemented to each other after the adhesive agent has hardened; and complete removal of material from the contact rings in the region where they touch at the end face, so that a peripheral, electrically insulating recess is produced along a circumferential line.

Slip-ring element and method for its manufacture

In a method for producing a slip ring brush, the slip ring brush including a brush element and a printed circuit board. The printed circuit board has a first surface and a second surface and has at least one printed circuit trace as well as at least one bore which penetrates the printed circuit board from the first surface to the second surface. An electrical contact between the brush element and the printed circuit trace is produced by soldering. The brush element is soldered such that solder penetrates from the second surface of the printed circuit board through the bore of the printed circuit board all the way to the brush element at the first surface.
