Abstract (en)

[origin: DE19507389A1] Proposed is a device for the transmission of signals between components (22, 19) fitted so that they can move relative to each other. Part of a first conductor (14) is housed in a first component (22) while part of a second conductor (15) is located in a second component (19) which is mounted on a bearing (21) so that it can rotate with respect to the first component (22). The bearing (21) is electrically insulated from the components (19, 22) by an insulating element (42) and an insulating sleeve (39). The first conductor (14) and the second conductor (15) are connected electrically to each other through the bearing (21), thus establishing permanent contact between the first conductor (14) and the second conductor (15).
