Abstract
The present invention provides a ribbon cable for conducting AC power and digital data signals. The ribbon cable includes a plurality of spaced, parallel, wire conductors arranged in a row, the conductors including power conductors adaptable for conducting AC power and data conductors adaptable for conducting digital data signals. A pliable insulating material holds together and electrically insulates the conductors. Conductive material, such as a conductive foil or conductive plastic, is disposed either on or inside the insulating material to shield the electromagnetic interference generated by the transmitted AC power from the data conductors. The ribbon cable is then folded in a protective outer jacket so that the conductive material is disposed substantially between the power conductors and the data conductors. This maximizes the electromagnetic interference shielding of the conductive material.
