Abstract
Spring loaded rotary connectors that comprise a first wiring board having one or more sets of electrically conductive concentric circuits or rings formed thereon, that has one or more raised contacts, or looped-shaped dimples, for every ring. In a first embodiment, the first wiring board faces a second wiring board having electrically conductive concentric rings or circuits that form contacts. The first wiring board is coupled to a moving (rotating) component while the second wiring board is coupled to a stationary component, or vice-versa. The sliding rings and dimples (contacts) on the adjacent wiring boards permit signals and power to be transferred from the moving part of the connector to the stationary part thereof. In a second embodiment of the connector, a second side of the first wiring board is configured to have the conductive rings and dimples, and a third wiring board that is substantially identical to the second wiring board is disposed adjacent to the first wiring board on the opposite side thereof from the second wiring board. Appropriate electrical conductors are connected to each active concentric ring of the wiring boards to provide electrical connection thereto.
