Abstract

What is described here is an arrangement for transmitting electrical signals and/or energy between parts that can be rotated relative to each other, whereof the part (transmitting part) on which the transmitter is disposed comprises at least two electrical conductors whose shape is adapted to the trajectory or path of movement and into which said transmitter feeds the signal to be transmitted in a symmetrical form, while the other part comprises the receiver (receiving part),The inventive arrangement excels itself by the combination of the following features:the conductors of said transmitting part are terminated in a largely reflection-free manner in the region opposite to said transmitter,the receiver is of a high-ohmic design and comprises conductors matched with the conductors of said transmitting part, which are not terminated in a reflection-free manner and which are coupled to the conductors on said transmitting part by galvanic, inductive and/or capacitive means.
