Abstract
A rotary connector that transfers electrical power and signals using conductive metallic balls confined by a nonmetallic spacer and conductive conduits that are formed on two opposed metal-backed printed wiring boards. The rotary connector transfers electrical signals and power from a stationary printed wiring board to a moving printed wiring board by way of the conductive balls disposed in some or all openings of the conductive conduits. Nonconductive balls may be used in some of the openings. The use of a relatively large number of balls disposed in the openings of the nonmetallic spacer mechanically balance the connector. The connector is sealed and its interior contains nonconductive lubricant to lubricate the balls and conduits.
