In one embodiment of the invention, the step that forms outer shielding layer in the step (4) comprises: (41) around described cable cable core, form foil shielding layer with Aluminium Foil Package; And (42) are in the peripheral braiding of described foil shielding layer one deck copper wire mesh braided layer.The coverage rate of described foil shielding layer is 100%, and the coverage rate of described copper wire mesh braided layer is 86%.Described copper wire mesh braided layer can be woven into tinned wird.
In another embodiment of the present invention, described copper wire mesh braided layer is directly to be that the copper cash weaving of 0.16mm forms by 120 lines.
In an embodiment more of the present invention, described insulating barrier is a polyfluorinated ethylene plastic.
Preferable, the set twisted wire in the described step (3) is to carry out stranded between the lay between the 50mm to 70mm.
Preferable, described conductor is a tinned wird, described obturator is that polypropylene dashes fiber crops (PP dashes fiber crops).
Compared with prior art, owing to adopt the produced cable of manufacture method of shielding cable for military industry equipment of the present invention, its main traverse line has interior copper wire mesh braided layer and polyester film outward, can effectively shield external interference, and its cable cable core further is coated with outer shielding layer outward, can further shield interference, improve the serviceability of equipment.Described cable serving adopts Thermoplastic Vulcanizate to make, its low smoke and zero halogen, environmental, and uvioresistant, also cold-resistant, therefore the shielded type cable that adopts cable making method of the present invention to make can satisfy military industry equipment in the abominable field work conditions needed of environment.
By following description also in conjunction with the accompanying drawings, it is more clear that the present invention will become, and these accompanying drawings are used to explain embodiments of the invention.
