Abstract
The utility model discloses a kind of flexibility anti-nuclear electromagnetic pulse wisdom information system cable, be followed successively by cable core, nonwoven layer, screen and oversheath from the inside to the outside; Described screen is three layers, is followed successively by silver-plated copper lenticular wire screen, magnetically soft alloy band screen and conduction Polyether-type thermoplastic polyurethane elastomer screen from the inside to the outside.The flexibility of cable of the present utility model is good, and bending property is high, and the external diameter comparing traditional cable reduces 5 ~ 10%, and weight reduces 10 ~ 15%, and shielding properties is good, and the construction of cable is simple, is easy to processing.
Description
Technical field
The utility model relates to a wisdom information system cable, particularly a kind of flexibility anti-nuclear electromagnetic pulse wisdom information system cable.
Background technology
Along with the develop rapidly of global electronic science and technology, the electronic countermeasures in modern war and the success or failure of the power of information countermeasure to war play vital effect.Modern weapon system-of-systems has used microelectronics program control all fully thus has reached informationization and the wisdom of height.But microelectronics program control wisdom information system is very easily subject to the impact of interference of outside strong-electromagnetic field and is destroyed, so the electromagnetic protection of weapon system-of-systems is particularly important, is related to the safety of weapon system-of-systems.The modern strategic arms most with deterrent force are exactly nuclear weapon, and nuclear explosion can produce high energy pulse electromagnetic field.Quite a few energy is had to discharge with the form of electromagnetic pulse during nuclear explosion, particularly third generation nuclear weapon, improve the electromagnetic pulse of 40% especially, to produce stronger electromagnetic pulse effect, reach the commander of destruction the other side, control, communication, wisdom information system, obtain the object of the initiative of war victory.
The screen of anti-nuclear electromagnetic pulse cable generally adopts the wrapped multilayer metal wire knitted that adds of multi-layer metal belts to combine both at home and abroad at present, this kind of structure exists that whole cable is hardened, structure relative complex, unbending shortcoming, can not meet the requirement that weaponry wisdom information system is soft to cable, external diameter is little.
Utility model content
The purpose of this utility model is to provide a kind of softness, bending radius is little, screening effectiveness is high, structure is simple, be easy to the flexibility anti-nuclear electromagnetic pulse wisdom information system cable of processing.
The technical scheme realizing the utility model object is a kind of flexibility anti-nuclear electromagnetic pulse wisdom information system cable, is followed successively by cable core, nonwoven layer, screen and oversheath from the inside to the outside; Described screen is three layers, is followed successively by silver-plated copper lenticular wire screen, magnetically soft alloy band screen and conduction polyether thermoplastic polyurethane termoplastic elastomer screen from the inside to the outside.
The material of described magnetically soft alloy band screen is corronil strap, and thickness is 0.09mm.
Described cable core is made up of four even stranded insulated wire cores, every root insulated wire cores by inside conductor and be wrapped in the perfluoroethylene-propylene insulating barrier of conductor outside.
Described conductor is that silver-gilt copper wire is stranded.
The thickness of described nonwoven fabrics is: 0.20mm.
After have employed technique scheme, the utility model has following beneficial effect: (1) screen of the present utility model adopts by silver-plated copper lenticular wire, magnetically soft alloy band, the screen that conduction Polyether-type thermoplastic polyurethane elastomer is formed, conduction Polyether-type thermoplastic polyurethane elastomer has electromagnetic interference/radio frequency interference shield, good combination can be woven with magnetically soft alloy band and silver-plated copper lenticular wire, make cable on the basis of traditional anti-nuclear electromagnetic pulse cable, at least can reduce by 2 layers of metallic shield, but the requirement of the screening effectiveness >=70db of nuclear electromagnetic pulse cable can be reached.Owing to decreasing at least 2 layers of metallic shield, the flexibility of cable therefore can be made greatly to improve, and the external diameter of cable and weight is corresponding minimizing also; Conductive thermoplastic elastomer not only has shielding action, but also has the characteristic of plastics concurrently, while the flexibility increasing cable, suitably can also reduce the external diameter of cable jacket.Under the silver-plated copper lenticular wire adopted is woven in shielding density and the immovable situation of screening effectiveness, decreases the also wire process needed for the braiding of round line, also make the corresponding minimizing of the external diameter of cable.
(2) flexibility of cable of the present utility model is good, and bending property is high, and the external diameter comparing traditional cable reduces 5 ~ 10%, and weight reduces 10 ~ 15%, and shielding properties is good, and the construction of cable is simple, is easy to processing.
