ELECTRIC CABLE SHIELD STRUCTURE

摘要

The present invention relates to a novel shield structure for an electric cable which is able to cut-off the effect of the external noises as low as the limit thereof. A metal sheet tape including magnesium as a major component thereof having high electro-magnetic shield performance, high vibration absorption performance as well as high heat conductivity being wound spirally on an outer circumference of the electric cable may provide a high performance shield layer. Furthermore in an AV cable, original sounds may be recovered with extremely high faithfulness by forming a shield layer with winding spirally the metal sheet tape, which includes magnesium as a major component and is wound in the counter clockwise direction in the direction viewed from an IN end to an OUT end of an AV cable.
