Abstract
A reactor having a coil surrounded by a magnetic shield formed of laminated magnetic sheets. Connecting members pass through the central opening of the coil and are clamped between sheets of the magnetic shield. Each connecting member comprises a pair of connecting plates having opposite ends expanded. They are inserted from opposite sides of the central opening of the core, and are fixed together. The expanded parts at both ends of the connecting member increases the friction, and reduces vibration and noises.
