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
The present invention relates to technical field of electric wires and cables, relate in particular to a kind of electric wire with super shielding properties.
Background technology
At present communication apparatus commonly used or equipment conduction signal all is to connect with electric wire, its outer field screen is common wire sheathing, the poor-performing of the anti-electromagnetic interference of this wire sheathing itself, and this wire sheathing is more loose, often use causes wiry coming off easily, thereby further have influence on the anti-electromagnetic interference of electric wire, cause capability of electromagnetic shielding further to reduce.Therefore, providing the strong electric wire of a kind of anti-electromagnetic interference capability is those skilled in the art's urgent problems.
Summary of the invention
In order to solve the problems of above-mentioned existence, the present invention aims to provide a kind of super shielding wire cable, and this electric wire has super shielding, and its anti-electromagnetic interference capability is strong.
The invention provides a kind of super shielding wire cable, comprise conductor wire core, multilayer dielectric layer and multiple layer metal braid, described conductor wire core comprises by the stranded single condctor that forms of silver-gilt copper wire and is wrapped in its first outer insulating barrier and forms, described metal screen layer is wrapped in outside the described conductor wire core, parcel the second insulating barrier outside the described metal screen layer; Described wire sheathing comprises the first wire sheathing and the second wire sheathing from inside to outside successively, be provided with the first separator between described the first wire sheathing and the second wire sheathing, isolate by the 3rd insulating barrier and the 4th insulating barrier respectively between the adjacent two layers in described the first wire sheathing, the first separator, the second wire sheathing; Described the first wire sheathing and the second wire sheathing adopt the silver-gilt copper wire of processing through stannize closely to work out; Described the first separator is the aluminium-plastic tape thin layer; Described insulating barrier adopts the PTFE transparent plastic material of corrosion-and high-temp-resistant to make.
Further, described wire sheathing also comprises the 3rd wire sheathing, and the 3rd wire sheathing is between described the second wire sheathing and described the second insulating barrier, and described the 3rd wire sheathing also adopts silver-gilt copper wire closely to work out.
Further, be provided with the second separator between described conductor wire core and described the first wire sheathing, described the second separator is magnesium plastic composite strip thin layer.
Further, between described the second separator and described the first wire sheathing, be provided with the 5th insulating barrier.
Further, described the second insulating barrier is that the polyfluorinated ethylene material is made.
Among the present invention, the wire sheathing of Spaced setting has increased the anti-electromagnetic-radiation ability of this electric wire greatly, and wire sheathing has further increased shielding properties by closely working out through the silver-gilt copper wire of stannize processing; Between the multiple layer metal braid, also be mingled with separator, further increased shielding properties; The arrangement of multilayer dielectric layer has increased intensity and the resistance to elevated temperatures of electric wire.
