When an existing common multi-core comprehensive data cable needs to be dragged, due to the influence of external force, an insulated single wire is likely to be stretched due to the fact that the conductor or insulation is stretched due to the external force, insulation resistance is reduced or insulation is defective, reliability of the cable is reduced when the cable is used, and insulation resistance is unqualified.
Disclosure of Invention
In view of the deficiencies in the prior art, the utility model provides a data transmission cable is synthesized to multicore that pitch is less, the compliance is good, transmission performance is good, and the reliability is high, difficult ageing and fracture.
The technical scheme adopted by the utility model is that: a multi-core comprehensive data transmission cable is characterized in that: the cable comprises an insulated single wire, a twisted-pair shielding wire set, a super-five cable, a filler, a non-woven fabric inner protective layer, a tinned copper wire shielding layer I and a polyurethane sheath; the cable core in the middle of the cable core is formed around the interior sheath of package non-woven fabrics outward to super five types of cables and three groups of two twisted-pair shielding group, has several insulating single lines outside the cable core in the middle, is equipped with several insulating single lines and several outside the several insulating single lines and fills the core, is equipped with interior sheath of non-woven fabrics, tinned wire shielding layer I and polyurethane sheath outside several insulating single lines and several fill the core in proper order.
The utility model has the advantages that: the utility model discloses a pitch ratio of three twisted pair shielding groups of inlayer cable cores of middle cable core and five types of cables is 12 times, and several insulating single line pitch ratios are 11 times, and several insulating single lines and several fill core pitch ratios and be 10 times the multicore transposition form that reduces in proper order, and this transposition form pitch is less, makes the cable softer.
On one hand, the insulated single wires and the aramid fiber filling cores are arranged in sequence, so that the possibility of interlayer dislocation of the insulated single wires is reduced, and the structure of the cable is more stable and flexible; on the other hand, the aramid fiber material has high tensile strength, and when the cable needs to be stretched, stretching and pulling of the insulated wire core are avoided, and the stretchability of the cable is improved.
The twisted pair shielding wire group of the cable and the conductive wire core of the insulated single wire both adopt a plurality of strands of silver-plated copper wire cores, the flexibility of the conductor is ensured by the twisting of the plurality of strands of single wires, the silver-plated material has good transmission performance, and particularly, in high-frequency transmission, the silver-plated copper conductor shows more superior performance than other plating conductors due to the influence of skin effect. When the cable is used for a long time, the service temperature of the silver-plated copper conductor can reach 250 ℃, and the oxidation resistance reliability of the wire core is improved.
The insulating layer of the insulating single wire is made of a polyfluorinated ethylene propylene material, the temperature resistance level is 200 ℃, the material has the excellent characteristics of oil resistance, various solvent resistance, smog resistance, chemical corrosion resistance and high and low temperature resistance, the high-frequency transmission is realized, the strong environmental adaptability is also kept, and the influence on the transmission performance or the pressure resistance of the cable caused by the aging of the insulating material is reduced when the cable is used for a long time.
The effect of stabilizing cable structure has been played to the non-woven fabrics inner sheath, and this cable adopts double-deck non-woven fabrics inner sheath, makes the cable compacter rounding, has better performance of buckling, has increased the friction between the insulating single line, has avoided after buckling because the insulating surface is smooth to cause the flexible phenomenon of insulating single line, has solved cable end when the welding, and insulating single line is owing to stretch out and draw back the potential safety hazard that the welding point drops.
The shielding layer of the cable is all a tinned copper wire braided shield, and has a good shielding effect when external signal interference exists; the sheath of the cable is made of flame-retardant polyurethane material, and the flame-retardant polyurethane material has the characteristics of flame retardance, smoke resistance, wear resistance, solvent resistance, high strength and the like, and has a good protective effect on the cable while the environmental performance is kept.
In a word, the cable is compact and round as a whole, good in transmission performance, high in reliability and flexibility, has the characteristics of strong flame retardance, high and low temperature resistance, wear resistance and the like, and is not easy to age or crack.
