Problems solved by technology

[0003] However, the mutual interference of the magnetic waves of the existing flexible cables can easily lead to adverse effects. In order to effectively isolate the interference of the signal magnetic waves, the commonly used flexible cables mostly use high-cost conductive cloth to cover the flexible cables with conductive cloth. In fact, the flexible cable with this structure not only has more processes, but also relatively increases the cost

Abstract

The invention relates to the technical field of flexible flat cables and particularly to an anti-electromagnetic interference flexible flat cable comprising a cable body, an upper insulating film and a lower insulating film, wherein the upper insulating film and the lower insulating film are respectively covered on the upper surface and lower surface of the cable body; two ends of the upper surface of the cable body are respectively provided with an exposed part; the upper surface of the upper insulating film and the lower surface of the lower insulating film are respectively provided with a shielding layer made of metal conductive powder; and two ends of the lower surface of the cable body are respectively provided with flat cable reinforcement plates corresponding to the exposed parts. When the anti-electromagnetic interference flexible flat cable is used, the surfaces of an upper insulating layer and a lower insulating layer of the cable body are respectively provided with the shielding layer made of the metal conductive powder, therefore, the anti-electromagnetic interference flexible flat cable has the characteristics of antimagnetic isolation, anti-electromagnetic interference and the like and can keep a stable signal transmission effect. In addition, the anti-electromagnetic interference flexible flat cable has the advantages of simple structure, reasonable arrangement, low manufacturing cost and the like.

Description

technical field [0001] The invention relates to the technical field of flexible cables, in particular to an anti-electromagnetic interference flexible cable. Background technique [0002] Flexible Flat Cable (FFC) is a component for signal transmission. It has the advantages of arbitrary winding and high signal transmission, so it is widely used in many electronic products. The flexible cable is used in conjunction with an electronic connector to transmit signals from one end to the other to achieve the purpose of signal transmission. [0003] However, the mutual interference of the magnetic waves of the existing flexible cables can easily lead to adverse effects. In order to effectively isolate the interference of the signal magnetic waves, the commonly used flexible cables mostly use high-cost conductive cloth to cover the flexible cables with conductive cloth. In fact, the flexible cable with this structure not only has more processes, but also relatively increases the c...
