Therefore, demand providing that a kind of shield effectiveness is good urgently, uvioresistant, anti-aging and cable environmental protection overcome above defective.
Summary of the invention
The object of the present invention is to provide a kind of improved shielding cable for military industry equipment, described cable shield is effective, uvioresistant, anti-aging and environmental protection, can satisfy being operated in the open-air required harsh conditions of military industry equipment.
For achieving the above object, cable provided by the invention comprises some leads, obturator, screen, paper bag band and serving, described lead comprises conductor and coats the insulating barrier of described conductor, described lead comprises at least one main traverse line, copper wire mesh braided layer and polyester film in described main traverse line also comprises, copper wire mesh braided layer is woven in the insulating barrier periphery of described main traverse line in described, described polyester film coats described interior copper wire mesh braided layer, described obturator is located in the space between the described lead, described lead and described obturator are twisted into the cable cable core, described screen coats described cable cable core, described paper bag band coats described screen, the described serving described paper bag band that is covered, and described serving is a Thermoplastic Vulcanizate.
In one embodiment of the invention, described screen is the double-level-metal screen.Preferable, described screen comprises aluminium foil lapping layer and copper wire mesh braided layer, described copper wire mesh braided layer is woven in described aluminium foil lapping layer periphery.Described copper wire mesh braided layer can be the tinned wird braid.Preferable, the coverage rate of described foil shielding layer is 100%, the coverage rate of described copper wire mesh braided layer is 86%.
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, totally ten in described lead, wherein said main traverse line has three.
In another embodiment of the present invention, described obturator is that two polypropylene dash fiber crops.
Preferable, described conductor is a tinned wird, described insulating barrier is a polyfluorinated ethylene plastic.
Compared with prior art,, can effectively shield external interference, and the cable cable core further is coated with screen outward, can further shields interference, the serviceability of raising equipment because the main traverse line of described cable has interior copper wire mesh braided layer and polyester film outward.Described cable serving adopts Thermoplastic Vulcanizate to make, and its low smoke and zero halogen is environmental, and uvioresistant, and also cold-resistant, therefore cable of the present invention 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.
