Example Embodiment

[0011] Such as figure 1 As shown, figure 1 It is a schematic diagram of the structure of a super shielded wire and cable in an embodiment of the present invention.

[0012] Such as figure 1 As shown, the present invention provides a super-shielded wire and cable, including a conductive core 1, a multilayer insulation layer and a multilayer metal braid, wherein the conductive core 1 includes a single stranded silver-plated copper wire A core wire and a first insulating layer wrapped around it. The metal shielding layer is wrapped outside the conductive core 1, and the second insulating layer 6 is wrapped outside the metal shielding layer. The metal braiding layer is composed of inner The outside includes a first metal braided layer 5 and a second metal braided layer 4 in turn. There is a first isolation layer 7 between the first metal braided layer 5 and the second metal braided layer 4, and the first metal braided layer 5. The first isolation layer 7 and the second metal braid...

Abstract

The invention discloses an ultra-shielding electric wire and cable, comprising a conductive wire core, a plurality of insulating layers and a plurality of metal braid layers. The metal braid layers comprise a first metal braid layer and a second metal braid layer from inside out in sequence. A first isolating layer is disposed between the first metal braid layer and the second metal braid layer. Two adjacent layers of the first metal braid layer, the first isolating layer, and the second metal braid layer are isolated by insulating layers. In the cable, the multilayer metal braid layers which are disposed at interval greatly improve electromagnetic radiation shielding capacity of the wire and cable, and the metal braid layers are woven tightly by silver-plated copper wires which is processed by stannizing, thereby further improving shielding performance. The isolating layers are disposed among the plurality of metal braid layers, thereby further improving shielding performance. Arrangement form of the plurality of insulating layers improves strength of the wire and cable and high temperature resistance performance.

Description

technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to an electric wire and cable with super-shielding performance. Background technique [0002] At present, the commonly used communication equipment or equipment conduction signals are connected by wires and cables, and the outer shielding layer is an ordinary metal braiding layer. The performance of this metal braiding layer itself against electromagnetic interference is poor, and this metal braiding layer The layer is relatively loose, and frequent use will easily cause the metal wire to fall off, which will further affect the anti-electromagnetic interference of the wire and cable, resulting in a further reduction in the electromagnetic shielding performance. Therefore, it is an urgent problem for those skilled in the art to provide a wire and cable with strong anti-electromagnetic interference capability. Contents of the invention [0003] In order to solve t...
