The cable has the characteristics of high hardness, high temperature resistance, wear resistance, stretching resistance and the like, and has the defects that the cable is high in hardness, insulation aging or stress cracking phenomenon can occur under long-term stress when the cable is used for a long time, attenuation is high when high-frequency transmission of a required signal is carried out, normal transmission of information cannot be guaranteed, and insulation reliability is reduced due to overhigh temperature of a conductor during field long-term use under a long-term working condition, a wire core or shielding oxidation is caused, and the transmission performance is influenced.
Disclosure of Invention
In view of the poor stability that prior art exists, the reliability is low, sinle silk and shielding are easy to oxidize, insulation is easy to split, transmission performance is unstable not enough under the high frequency, the utility model provides a battlefield field composite cable has overcome the not enough that prior art cable structure exists.
The utility model adopts the technical proposal that: a battlefield field integrated cable, 7 high temperature resistant radio frequency cables, 7 fluorinated ethylene propylene insulation shielding mounting wires, 19 0.2mm fluorinated ethylene propylene insulation mounting wires and 5 0.75mm fluorinated ethylene propylene insulation mounting wires constitute an intermediate cable core, dacron silk I is tied up to the intermediate cable core outward, 11 fluorinated ethylene propylene insulation twisted pair shielding wires and 8 0.75mm fluorinated ethylene propylene insulation mounting wires constitute a main body cable core are arranged outward to the dacron silk I, tie up dacron silk II, weave dacron silk inner sheath and 105 ℃ flame retardant polyvinyl chloride sheath are arranged outward to the main body cable core in proper order.
The utility model is characterized in that: the cable orientation is a comprehensive data transmission cable designed for field communication signals, a high-temperature-resistant radio-frequency cable insulating layer in the cable adopts polytetrafluoroethylene to push the insulating layer, the concentricity of the insulating layer is as high as 95% or more, the extrusion type in the market is usually 85% or more, the high concentricity ensures that the impedance tolerance of the product is stabilized at +/-3 omega, and the market usually requires +/-10 omega;
the outer protective layer is made of glass fibers and coated with organic silicon paint, so that the high temperature resistance of the cable is improved, the long-term use temperature is up to 200 ℃, the short time is 350 ℃, the time is 40min, and most cables in the market can resist the temperature of 150-200 ℃. The cable can work under the high-temperature condition and has information communication services of data transmission, and the like, signals can still be transmitted under the high frequency of 3000MHz due to the high concentricity of the high cable, information attenuation cannot be caused under the high temperature and high frequency, and the application frequency of other cables in the market is basically 300 MHz-1000 MHz.
The first layer of the cable adopts 3 high-temperature-resistant radio-frequency cables as the middle core, and the second layer of the cable adopts a combination form of the high-temperature-resistant radio-frequency cables and a perfluorinated ethylene propylene insulation shielding mounting wire for twisting, thereby not only meeting the transmission requirement of signals, but also meeting the welding requirement of the cable and the connector;

The silver-plated copper conductor and the shielding wire adopted by the cable are all subjected to passivation treatment, and the passivated conductor or shielding is more oxidation-resistant through tests. It is found that the oxidation of the conductor or shield mainly reacts with sulfur and oxygen in the air, which causes yellowing or blackening of the surface of the silver-plated conductor or shield, and further affects the use of the product. The conductor and the shield of the cable can not change color after being soaked in a sodium polysulfide solution for 5min after being passivated, and yellow spots or black spots can appear on common conductors and shields in the market after being soaked in the sodium polysulfide solution for about 1 min. The polyester yarn protective layer increases the strength and light resistance of the cable, and ensures the stability and reliability of the cable in field use.
The flexibility of the product is improved by adopting a multilayer stranded cable mode, the minimum bending radius can reach 10D, and the bending radius of the product in the market is 15-20D; the use function of the cable is enriched by the combination form of the radio frequency cable, the insulated single wire and the shielding twisted pair. The main cable core is stranded by adopting a gradually decreased stranding pitch-diameter ratio layer by layer, the first layer is stranded by a 15-fold pitch-diameter ratio, the second layer is stranded by a 14-fold pitch-diameter ratio, the third layer is stranded by a 13-fold pitch-diameter ratio, and the fourth layer is stranded by a 12-fold pitch-diameter ratio. The common cable in the market can generate workshop dislocation or structural collapse when being subjected to tension of about 10N; in consideration of the field environment, the silver-plated copper wire core is used as the whole cable conductor, the polyperfluorinated ethylene propylene is used as the insulation, and the temperature resistance grade of the cable is improved to 200 ℃ for a long time. Compared with the common cable, the terylene yarn is used as the inner protective layer, so that the flexibility of the cable is improved, the strength and the light resistance of the cable are improved, and the problem of low reliability of the cable caused by poor light resistance of the common cable in field use is solved.
