Embodiment
Referring to Fig. 1; A kind of pair of novel filling super-six type unshielded data communication of sheath paired cable: comprise the cable inner core and be coated on this cable inner core outer sheath 2 and outer jacket 1 successively; The cable inner core comprises four groups of twisted pair wires 3 and packing 4, and packing is two back-to-back and the U-shaped shape that staggers each other and form two cut sections: first cut section 5 and second cut section 6; Every group of twisted pair wire is made up of with different pitch twistings two heart yearns, and every heart yearn is made up of conductor 7 and the outside insulating barrier 8 that coats; First and second group twisted pair wire is arranged in first cut section, and third and fourth group twisted pair wire is arranged in second cut section; The medial surface indention of outer jacket; The cable inner core that four groups of twisted pair wires and packing form is stranded in the said sheath with same pitch.
Novel packing 4 moulds fat (FEP) by PEF (PE) or fluorine or Halogen (LSZH) material is processed, and inner sheath 2 moulds fat (FEP) by polyvinyl chloride (PVC) or fluorine respectively with outer jacket 1 or Halogen (LSZH) material is processed.
Become cable to add novel packing 4 earlier, outwards coat sheath 2 again, coat zigzag outer jacket 1 at last; Outside novel packing and zigzag, can prevent in use between the adjacent cables like this under layer by layer the effect effectively or extraneous electromagnetic interference.
The cored wire conductor 7 of the paired cable of the utility model is to be that hypoxemia or the oxygen-free copper bar of 2.6mm processed through wire drawing, annealing by diameter, and the wire gauge of conductor 7 is (23～24) AWG; The insulating barrier of heart yearn is moulded fat (FEP) material by high density polyethylene (HDPE) (HDPE) or fluorine and is processed, thickness of insulating layer be 0.26+/-0.02mm; Two heart yearns of twisted pair wire are the twisting shape, and four pairs of lines all adopt the back twist of (30～60) % technological; Adopt between four pairs of twisted pair wires width be 4.10+/-0.1mm, highly be 6.20+/-0.1mm, outward flange thickness be 0.50+/-0.1mm, interior thickness be 0.50+/-0.1mm two back-to-back and the U-shaped packing that staggers; Duplex sheath is moulded fat (FEP) material by polyvinyl chloride (PVC), polyethylene (PE), low smoke and zero halogen (LSZH) or fluorine and is processed; The thickness of internal layer sheath be 0.35+/-0.05mm, the maximum ga(u)ge 0.60+ of sawtooth pattern outer protective sleeve/-0.05mm, the thickness of the thinnest point be 0.30+/-0.05mm; Finished product is an ellipse; Average line footpath 7.15+/-0.2mm, the outer protective sleeve sawtooth is that 16 teeth are evenly distributed on the interior circular shaft of outer protective sleeve, the height of sawtooth be 0.30+/-0.05mm.
The paired cable of the utility model has four important unit for electrical property parameters: impedance, decay, electromagnetic interference, return loss the time have taken into full account this balanced relation in design.
Impedance is a parameter the most basic in the electric property, and it is by conductor lines footpath, two conductor centre-to-centre spacing, these three parameter determining of insulative dielectric constant, and not matching of any impedance all can cause the error of final acknowledge(ment) signal.Therefore when design, taken into full account the influence of these three factors, the conductor lines footpath is big, and low cut can be got well, but cost raises, and finish line footpath is bigger than normal; The conductor lines footpath is little, and decay can be influenced.Consider also simultaneously when producing that pitch is different and tension force is inconsistent; Can produce each line two conductor centre-to-centre spacing difference is influenced impedance; Go out different insulated wire footpaths according to different multiple twin pitch design, the right resistance value of every line is controlled at about the nurse difficult to understand of 100+/-15 behind the assurance finished product.
Decay is divided into conductor decay and diectric attenuation two parts, and the conductor decay is relevant with resistance, therefore adopts oxygen-free copper or hypoxemia copper product, makes resistance reach minimum; Diectric attenuation is relevant with material, and insulating material selects for use high density polyethylene (HDPE) (HDPE) or fluorine to mould fat (FEP) material, all is the smaller material of dielectric constant and dielectric loss angle.
Aspects such as it is directly little with line that the superior performance of this wire rod is embodied in anti-electromagnetic interference, and cost is low.The design of this novel filling and duplex sheath obtains an on-circular cross-section and makes that cable product line footpath is little; Stability of structure is good, and this novel filling effectively keeps every pair of line to separate in cavity, and the position interfixes each other; This in addition novel filling has reduced the dielectric constant in the whole cavity substantially; Effectively improve the decay of every twisted pair wire, make the field decay farthest between each twisted pair wire and another twisted pair wire, thereby improve electromagnetic interference and fade performance.Simultaneously because the ingenious design of this novel filling can not only solve the dried certificate of electromagnetism in the group between the inner toe-in of cable; Improve decay, also come effectively to solve to do sorrow, because this novel rectangle that is filled to from the electromagnetism between adjacent cables; With each line to ovalisation behind the stranded coating sheath in addition; This oval-shaped cable can increase when leading cable combination together mutually the adjacent cables center line between distance, the effect of duplex sheath simultaneously also be increase the adjacent cables center line between distance, thereby because of between this dual effect group that effectively improvement surpasses six types down, going here and there according to problem; It is little not only to have the line footpath; The more and more littler characteristics of particularly crosstalking between increase group with frequency. and handling ease, save material, be a getting twice the result with half the effort. Eco-power new product.
Return loss receives the influence of input impedance; Since with load impedance do not match or make in the inhomogeneous point in cycle; Thereby the reflection that produces signal; Input impedance is fluctuateed up and down at characteristic impedance value, and the energy of reflection aggravates along with the increase of frequency, even can produce the sudden change significantly of return loss.The utility model adopts the preparatory back twist technology of pair twist, eliminates the influence of periodic inconsistent generation to input impedance, improves the stability of input impedance, thereby optimizes return loss.
