Slipring with a slide track formed as a closed circuit of electrically resistant material

Abstract

A device such as a slide track or a slipring for transmitting electrical energy or signals between at least two units that are rotatable relative to each other along a path of rotation comprises at least one slide track formed as a closed circuit of electrically conducting material disposed along the path of rotation, and at least one tap movable along the slide track for coupling electrical signals into the slide track from one of the units, or coupling electrical signals out of the slide track to one of the units. In order to reduce a superposition of signals that have traveled along different directions along the closed circuit, the at least one slide track is configured to have electric losses resulting in an amplitude of an electrical signal coupled into the slide track being reduced by at least 6 dB, preferably 10 dB, during a passage of the signal along one entire length of the slide track.
