Slip-ring unit with circuit board e.g. for remotely control camera, has torque required for movement between rotor and stator, introduced via circuit board fixed on rotor

摘要

A device for transmitting electrical currents, has a slip-ring unit (2) with rotor (2.2) and stator (2.3) and a circuit board (1), the conductor paths of which are in electrical connection with the connection wires (2.1) of the rotor (2.2) and stator (2.3). The torque for the rotor movement between the rotor and the stator is introduced via the circuit board (1) fixed on the rotor, or the circuit board (1) is used as a torque arm/bracket.
