1. A flat cable, comprising:
- (a) a first power conducting layer, wherein said first power conducting layer comprises a first power conductor, and the width of said first power conductor is more than half of the width of the cable; and
(b) a second power conducting layer beneath said first power conducting layer, wherein said second power conducting layer comprises a second power conductor, and the width of said second power conductor is more than half of the width of the cable, and wherein said second power conductor further comprises a conducting tab folded around said first power conducting layer forming an electrical connecting pad over said first power conducting layer on a side of said first power conducting layer opposite said second power conducting layer.

Abstract
A multi-layered, flat, flexible cable capable of transmitting both power and multiple control signals to the components of a network is disclosed. The cable provides all connections on its top surface using a via-less design that does not reduce the cross-sectional area of power and ground buses within the cable. This effect is achieved through the use of folded conducting tabs appearing at periodic intervals along one of the power and ground conducting layers, which are folded over onto the top of the cable for electrical connection thereto.
