The invention discloses an anti-electromagnetic-interference flexible cable which comprises a plurality of wire cores. Each wire core comprises a conductor and an insulating layer wrapping the conductor. The wire cores are arranged in parallel, and cable cores composed of filler are arranged in arrangement gaps of the wire cores. A cable core isolation belt, an electromagnetic shielding layer formed by braiding annealed copper wires, a shielding isolation layer and an outer sheath are wrapped on the cable cores in sequence from inside to outside. According to the anti-electromagnetic-interference flexible cable, the electromagnetic shielding layer formed by braiding the annealed copper wires and the shielding isolation layer have very good anti-electromagnetic-interference performance and effectively increase the shielding suppression coefficient, so the anti-electromagnetic-interference flexible cable can be applied to various mobile electrical devices in an environment with complex electromagnetic wave interference, resist interference from external electromagnetic waves, guarantee the safety, stability and reliability of various current signals in transmission without causing distortion, and effectively protect safe operation of the electrical devices at the same time.
Description
technical field [0001] The invention relates to the technical field of cables, in particular to an anti-electromagnetic interference flexible cable. Background technique [0002] Shielding is the isolation of metal between two spatial regions to control the induction and radiation of electric fields, magnetic fields and electromagnetic waves from one region to another. Specifically, it is to surround the interference source of components, circuits, assemblies, cables or the whole system with a shield to prevent the interference electromagnetic field from spreading outward; to surround the receiving circuit, equipment or system with a shield to prevent them from being affected by the outside world. The influence of electromagnetic fields. Because the shield absorbs energy (eddy current loss), reflects energy (interface reflection of electromagnetic waves on the shield) and counteracts energy (electrical Magnetic induction generates a reverse electromagnetic field on the shi...
