Description of drawings
Below, with reference to accompanying drawing, for those skilled in the art that, to the detailed description of the present utility model, above-mentioned and other purposes of the present utility model, feature and advantage will be apparent.
Fig. 1 is a cross-section of cable schematic diagram of the present utility model;
Fig. 2 is that the cable in the utility model manufacturing process twines schematic diagram.
Embodiment
As shown in Figure 1, four couples, the six class grid lines 10 and 20 that non-screen data communication symmetrical cable of the present utility model is established by cross packing 30 folders, outer successively by the PP foaming be with 40, conductive strips or semi-conductive tape 50 form with sheath 60, so just formed a novel 10G Ethernet that is used for non-shielding symmetric data cable.
Specifically, the every heart yearn 10 in this data symmetrical cable is to be made up of conductor 11 and the insulating barrier 12 that is coated on conductor 11 outer surfaces; Conductor 11 adopts the hypoxemia soft copper, helps to improve the signal transmission rate of wire rod, and the performance that improves the anti-bending of conductor.Insulating barrier 12 all adopts the materials of low-ks, low dielectric loss, has reduced line as much as possible to the signal attenuation at high band, and insulated wire footpath may command gets lessly, has saved material during making, also the space of having saved poling for wiring.
In the utility model, through wire drawing and stranded the making of annealing, the specification of conductor 11 is the solid conductor of 23AWG to the conductor 11 of heart yearn 10 by hypoxemia copper or oxygenless copper material, and nominal diameter is 0.58mm.And insulating barrier 12 is made by high-density polyethylene (HDPE) material, and the insulation nominal diameter is 1.08 ± 0.05mm.
It is right that per two heart yearns 10,20 of said structure are twisted into line, has 4 pairs of lines, and the cross packing 30 that the centre of 4 pairs of lines has a low dielectric material to make is crosstalked in the effectively reduction group; Two heart yearns of this twisted pair wire are the twisting shape, and the 4 pairs of lines all adopt the back twist technology of (20～60) %.Add cross packing 30 in the middle of during four pairs of line strandings, cross packing 30 is by polyethylene (PE) material, and width is about 5.5 ± 0.2mm, and thickness is 0.6 ± 0.15mm.Outside at said structure, coat successively that foaming is with 40, conduction or semi-conductive tape 50, by sheath 60, wherein, Fig. 2 illustrates and is coating the intermediate 100 further process engineerings that adopt conductive strips or semi-conductive tape 50 spirals to twine that foaming forms with 40 backs outside last.Thisly increase foaming on the basis with 40 and the coating mode of conductive strips or semi-conductive tape 50 uniquenesses crosstalking between the adjacent lines group when cable pencil is tied up can effectively suppress to connect up the time filling based on cross, guarantee the 10G cable at a high speed, transmission signals and image effectively, has easy production, the effect of stable performance.
High-speed data communication paired cable of the present utility model has 5 important unit for electrical property parameters: cross-talk etc. between impedance, decay, return loss, cross-talk (in the group), group has taken into full account five equilibrium when 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 the parameter decisions of insulative dielectric constant, and not matching of any impedance all can cause the error of final acknowledge(ment) signal.The utility model the time has taken into full account the influence of these three factors in design, and 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 little decay meeting in footpath is influenced.Considering when producing the different and tension force of pitch, inconsistent can to produce each line different and influence impedance to two conductor centre-to-centre spacing, go out different insulated wire footpaths according to different multiple twin pitch design, the right resistance value of every line is controlled at about 100 ± 150hm behind the assurance finished product.
Decay is divided into conductor decay and diectric attenuation two parts, and the conductor decay is relevant with resistance, so we adopt oxygen-free copper or hypoxemia copper product, makes resistance reach minimum; Insulating material is selected high density polyethylene (HDPE) (HDPE) material for use, all is the smaller material of dielectric constant and dielectric loss angle.
Return loss is subjected to the influence of input impedance, because and load impedance do not match or make in the inhomogeneous point in cycle, and the reflection that produces signal, input impedance is fluctuateed up and down at characteristic impedance value, the energy of reflection aggravates along with the increase of frequency, even can produce the sudden change significantly of return loss.Adopted the pre-back twist technology of pair twist in the design, eliminated the influence of periodic inconsistent generation, improved the stability of input impedance, thereby optimized return loss input impedance.
The design of cross-talk is to be based upon on the pitch of original six class lines in the group, the pitch design of original six class lines is supported the frequency of 250MHz only, and existing 10G wire rod requires to possess crosstalking above 500MHz, so suitably reduced the pair twist pitch during design, and used the statistical method of Six Sigma experimental design to select best pitch, thereby satisfied the requirement of crosstalking in the group, real system can satisfy the qualified index of crosstalking of 1000MHz.
One of performance that high-speed data communication paired cable of the present utility model is superior, be embodied in crosstalk between anti-group on.When traditional non-shielding six class data communication paired cable designs can't solve frequency and extend to high frequency, the interference of adjacent lines group same pitch line centering transmission signals.Crosstalk between solution group effectively, and the wire rod softness, be easy to wiring, and save material, be a getting twice the result with half the effort. Eco-power new product.
More than all embodiment only for the explanation the utility model usefulness, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or variation, so all technical schemes that are equal to also should belong to category of the present utility model and should be limited by each claim.
