Embodiment
A kind of Fast Ethernet type of resistance to UV of blocking water horizontal symmetrical data cable as shown in Figure 1, comprise cable inner core, and be coated on the sheath of cable inner core outside, described cable inner core is twisted together by some groups of twisted pair wires 2, described cable inner core also comprises packing 4, and some groups of twisted pair wires 2 are separated by described packing 4.Described twisted pair wire 2 comprises the heart yearn of stranded setting, and described heart yearn is made up of conductor 6 and the insulating barrier 5 that is coated on conductor 6 outside, in described cable inner core, be filled with dubbin layer of paste 1.
Specific embodiment: as shown in Figure 1, described cable inner core is twisted together by four groups of twisted pair wires 2, described packing 4 is in cross, sheath lumen is divided into four districts by this packing 4, described four groups of twisted pair wires 2 are distributed in four districts, between described some twisted pair wires 2, be also provided with shim 3, and described shim 3 is in " ten " font, the width of described shim is 4.5 ± 0.3mm, and thickness is 0.35 ± 0.15mm; In order to play the auxiliary effect blocked water, and sheath can be utilized to carry out the acquisition of resistance to UV function, described sheath comprises oversheath 8 and inner sheath 7, and described oversheath 8 is made by adding carbon black in nylon material, and the thickness of this oversheath is 0.4 ± 0.05mm; Described inner sheath 7 is made up of LLDPE, and the thickness of this inner sheath is 0.5 ± 0.05mm; In order to make whole cable in the wire diameter ensureing to reduce under the prerequisite that impedance meets the demands wire rod, cost of manufacture is reduced, described conductor 6 is that copper cash adopts solid or stranded shape to form by main body, described insulating barrier 5 adopts high density polyethylene (HDPE) to pass through foaming and is formed, this insulating barrier 5 from inside to outside includes internal layer 51, foaming layer 52 and outer 53, the thickness of insulating barrier 5 is 0.26 ± 0.02mm, this insulating barrier adopts the material of low-k, low dielectric loss, reduces effective dielectric constant, the dielectric loss angle of insulating barrier.
The high-speed data communication paired cable that the technical program obtains has 4 important unit for electrical property parameters: impedance, decay, return loss, cross-talk (in group) etc., taken into full account the equilibrium of four when designing.
Impedance is parameter the most basic in electric property, and it is determined by conductor wire diameter, two conductor centre-to-centre spacing, these three parameters of insulative dielectric constant, any impedance do not mate the error that all can cause final acknowledge(ment) signal.We have taken into full account the impact of these three factors when designing, conductor wire diameter is large, and low cut can be got well, but cost raises, and final wire diameter is bigger than normal; The little decay of conductor wire diameter can be influenced.Owing to being filled with ointment, causing the effective dielectric constant of cable core to change, need the impedance of particular design insulation core wire; The heart yearn impedance design of original unshielded cable is 100 Ω, and in order to offset the impact of ointment, the impedance of newly-designed heart yearn improves 5 Ω, and the impedance of the finished cable of such actual production maintains 100 Ω of standard.When considering production, inconsistent to produce each line different and affect impedance on two conductor centre-to-centre spacing for the different and tension force of pitch, go out different insulation wire diameters according to different multiple twin pitch design, the resistance value that after ensureing finished product, every line is right controls at about 100 ± 150hm.
Decay is divided into conductor to decay and diectric attenuation two parts, and conductor decay is relevant with resistance, so we adopt oxygen-free copper or hypoxemia copper product, makes resistance reach minimum; HDPE and blowing agent are selected in insulation, are all the smaller materials of dielectric constant and dielectric loss angle, and adopt foaming structure, again reduce the effective dielectric constant of material, improve the decay of product.
Return loss is by the impact of input impedance, due to not the mating or the uneven point in cycle in making of load impedance, and produce the reflection of signal, input impedance is fluctuated up and down at characteristic impedance value, the energy of reflection aggravates along with the increase of frequency, even can produce the significantly sudden change of return loss.Have employed the pre-back twist technology of pair twist in design, eliminate periodically inconsistent the impact produced input impedance, improve the stability of input impedance, thus optimize return loss.
In group, the design of cross-talk is based upon in the pitch of original CAT5E UTP cable, the pitch design of original CAT5E UTP cable can support the frequency of 100MHz, and existing wire rod requires the crosstalk more than 250MHz, therefore suitably reduce pair twist pitch during design, separate with packing, and used the statistical method of Six Sigma experimental design to have selected best pitch, thus met the requirement of crosstalk in group, real system can meet the qualified crosstalk index of 250MHz.
The raw material usage that the cable of the technical program reduces cable on the basis keeping block-water performance is one of superior performance of this high-speed data communication paired cable, foamed insulation structure can solve the problem of Insulation Material consumption to a certain extent, is a Eco-power new product.
It is emphasized that above is better implementation column of the present utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
