ABSTRACT:
Planetary connectors for coupling signals and power between stationary and moving structures. The planetary connector comprises a pressure plate that abuts a conformal pad that in turn contacts a first printed wiring board having a plurality of concentric conductive rings that face the interior of the connector. A second printed wiring board, which may be backed by a second pressure plate, is disposed at an end of the connector distal from the first printed wiring board that has a plurality of concentric conductive rings 18a that face the interior of the connector. A ball bearing retainer that retains a plurality of metal ball bearings is disposed between the flexible printed wiring boards, such that the ball bearings make electrical contact with the conductive rings of the rigid printed wiring boards. A shaft extends through all components. A selected printed wiring board is mounted to a rotating structure and the other printed wiring board is mounted a stationary platform, and a plurality of bearings are coupled to the shaft that allow the selected printed wiring board to rotate relative to the other printed wiring board. One embodiment of the connector comprises a flexible printed wiring board and a rigid printed wiring board. Another embodiment of the connector comprises two flexible printed wiring boards.
