[0002] Flat cables have the advantages of small footprint and warpability, and are widely used in various electronic devices for signal transmission. Conventional flat cables include a number of conductors arranged at intervals on the left and right, insulating sheets wrapped on the upper and lower surfaces of the conductors, and insulating sheets covering the insulation. However, in the process of signal transmission, especially in the process of high-frequency signal transmission, the flat cable is extremely susceptible to interference from external electromagnetic signals, so it is often necessary to improve the internal structure of the flat cable

The present invention relates to a flat cable. The flat cable comprises a plurality of differential signal conductors, at least one grounding conductor, insulated leather and a covering layer. The insulated leather warps the outer sides of the differential signal conductors and the at least one grounding conductor, and the covering layer covers the outer side of the insulated leather. The flat cable further comprises metal conductive pieces in electrical contact with the at least one grounding conductor, the insulated leather is provided with open holes, the at least one grounding conductor isexposed in the open holes, at least one part of the metal conductive pieces is held at the open holes and is in electrical contact with the at least one grounding conductor, and therefore, the at least one grounding conductor are electrically connected in series through the covering layer or the metal conductive pieces to form a common grounding path so as to improve the grounding effect and a signal shielding function.
