Electrical device with flexible connectors

An electrical device, comprising:

• a first printed wiring board including a first interconnect;
• a second printed wiring board including a second interconnect;
• a continuous ring-shaped first flexible connector disposed between the first printed wiring board and the second printed wiring board, the continuous ring-shaped first flexible connector defining an annular space and including:
• a first flexible conductor and a second flexible conductor;
• a flexible insulator disposed between the first flexible conductor and the second flexible conductor;
• a continuous ring-shaped second flexible connector disposed within the annular space and spaced apart from the continuous ring-shaped first flexible connector to define a continuous ring-shaped annular region between an interior of the continuous ring-shaped first flexible connector and an exterior of the continuous ring-shaped second flexible connector, the continuous ring-shaped second flexible connector being disposed between the first printed wiring board and the second printed wiring board and including a third flexible conductor;
• wherein the first interconnect electrically connects the first flexible conductor and the third flexible conductor, and the second interconnect electrically connects the third flexible conductor and the second flexible conductor, wherein the second interconnect is disposed opposite the first interconnect;
• and
• a ring-shaped core disposed in the ring-shaped annular region defined between the interior of the continuous ring-shaped first flexible connector and the exterior of the continuous ring-shaped second flexible connector,
• wherein respective upper and lower ends of each of the continuous ring-shaped first flexible connector, the continuous ring-shaped second flexible connector and the ring-shaped core are coplanar at the respective innermost surfaces of the first and second printed wiring boards, respectively.
