Abstract

The invention discloses an anti-interference cable. The anti-interference cable comprises a wire core, an insulating layer, an outer sheath and a metal corrugated pipe; the surface of the wire core is coated with a copper net; the copper net is arranged in a permanent magnet manner; the insulating layer comprises polyvinyl chloride resin, a barium titanate thin film and polyester fiber cloth; the copper net is embedded in the polyvinyl chloride resin; an epoxy resin binder is arranged between the polyvinyl chloride resin and the barium titanate thin film; the surface of the barium titanate thin film is coated with the polyester fiber cloth; the surface of the polyester fiber cloth is subjected to carbon plating; EVA foam is arranged between the outer sheath and the polyester fiber cloth; a ferrite magnetic ring is arranged on the outer sheath; a joint bearing is mounted on the metal corrugated pipe; the ferrite magnetic ring is mounted in the joint bearing; and the surface of the metal corrugated pipe is subjected to silver plating. The anti-interference cable has excellent electromagnetic shielding capability.

Description

technical field [0001] The invention relates to an anti-interference cable. Background technique [0002] Cables are used to transmit electric (magnetic) energy, information and wire products that realize electromagnetic energy conversion. Cables in a broad sense are also referred to as cables for short. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection composed of the following parts; One or more insulated wire cores, and their respective possible covering layers, total protective layer and outer sheath, and the cable may also have additional uninsulated conductors. Wire products used to transmit electric (magnetic) energy, information and realize electromagnetic energy conversion. [0003] The radiation and leaked electromagnetic waves of cables not only seriously interfere with the normal operation of other electronic equipment, but also lead to equipment dysfunction and transmission errors. Therefore, reducing the electromagnetic...
