Preferably, the first sheath and the second sheath are both made of thermoplastic insulating butyronitrile materials, the thickness of each sheath does not exceed 1 mm, and the effects of insulation, high temperature resistance, low smoke and low halogen are achieved.

Preferably, the shielding layer is made of a soft magnetic material, the thickness of the shielding layer is not less than 0.6 mm, the soft magnetic material has the electromagnetic interference isolation effect, and the braid layer is matched to achieve a double anti-interference effect.

Preferably, the braided layer is made of red copper or tinned copper material and is braided in a warp-weft staggered mode, the braided layer needs to be grounded, and external interference signals can be guided into the ground by the layer.

Preferably, the wearing layer is made by polyvinyl chloride material, coats on the outer wall of wearing layer and has the fireproof paint layer, can play a wear-resisting effect, avoids when assembly or transport the cable, and the wearing and tearing appear.

Preferably, the wire core is made of a zinc-plated copper material, so that stability of signal transmission is guaranteed.

Preferably, the filling layer is made of synthetic resin materials, so that the compactness inside the flat cable can be guaranteed, and the condition that the inner wire cores are distributed and dislocated when the flat cable is bent is avoided.

Compared with the prior art, the beneficial effects of the utility model are that: can play a dual anti-interference effect through shielding layer and weaving layer to improve sinle silk signal transmission's stability, and the filling layer that sets up between two sheaths can improve the closely knit degree between the second sheath, guarantee cable structure's stability.
