Problems solved by technology

Although these materials are light in weight and corrosion-resistant, their electromagnetic shielding performance is generally inferior to that of metals, and their strength is low, so they are not suitable for structural materials. The existing shielded cables have the defect of poor shielding due to the defects of shielding materials.

Abstract

The invention discloses shielded cables and particularly relates to a shielded cable and a preparation method of a magnesium alloy foil material in the shielding layer of the shielded cable. The shielded cable comprises at least one wire, wrapping layers, an inner protecting jacket, a shielding layer, an outer protecting jacket and a waterproof layer and is characterized in that one wrapping layerwraps each wire, the inner protecting jacket wraps the wrapping layers, the shielding layer wraps the inner protecting jacket, and the outer protecting jacket wraps the shielding layer; the shieldinglayer of a magnesium alloy shielding layer, and the waterproof layer is arranged between the inner protecting jacket and the shielding layer. The prepared shielded cable has the advantages that the shielded cable is simple in structure, lightweight, good in shielding effect, high in tensile strength, durable, resistant to corrosion and long in service life; the shielding layer is low in density,and the preparation process is simple, mature, and high in yield.

Description

technical field [0001] The invention relates to a shielded cable, in particular to a shielded cable and a method for preparing the magnesium alloy foil in the shielding layer. Background technique [0002] With the rapid development of the modern electronic industry and the widespread use of electronic and electrical products, electromagnetic interference has become a new social hazard. On the one hand, electromagnetic radiation will affect people's health, and it will cause serious interference to the surrounding electronic equipment, which will cause their working procedures to be disordered and produce wrong actions; on the other hand, electromagnetic radiation will leak information and make computers and other equipment No information security. Some data show that within a distance of 1 kilometer, the electromagnetic waves of the computer display terminal can be stolen and the information can be restored, resulting in a loss of confidentiality. In order to prevent inte...
