Appts. for signal transmission between two end points e.g fixed and movable vehicle parts

摘要

The appts. transmits signals between two end points one of which is movable relative to the other. The two end points are connected to each other via at least one lead running through a winding. Further outgoing leads are connected to the two end points. The lead is inserted in a circular ring shaped cassette. The cassette includes a stator carrying one of the end points and a rotor carrying the other end point. The rotor rotates opposite the stator axis in the opposite direction to the stator. The lead windings are divided into an inner coil region and an outer coil region with a different winding direction. A u-shaped reversal point (13) is arranged between the inner and outer regions. A ring shaped guide body (14) between the two coil regions surrounds the reversal point (13). the guide body (14) is movable in the circumferential direction of the cassette. The guide body (14) is formed in one piece. It has at least two coil zones (15,16). These zones are separated from each other and lie next to each other in the axial direction. The lead (10) is divided into the same number of partial leads (18,19) as the number of zones (15,16). Each partial lead is arranged in a coil zone. The winding directions of the partial leads are different for partial leads in corresponding coil regions connected via the reversal point (13).
