Abstract
A flexing connector for suppressing electromagnetic radiation from an electrical cable connecting moving and stationary elements of a machine has a shield surrounding a signal cable which includes an inner coil of wire wound in a generally helicoidal form with a flat cross-section with the signal cable positioned within the coil. An outer coil similar to the first, but with somewhat larger cross-section and wound with a different chirality, surrounds the inner coil. The coils are made from hardened steel, which is both electrically conductive and ferromagnetic. The two coils and the cable are clamped together on either side of a moving loop extending between the moving and stationary elements so that the coils cannot elongate and spread their windings apart as the connector is flexed.
