Fig. 1 is structural representation of the present utility model.
In figure: 1, center-filled bar; 2, twisted pair wire; 3, outer jointing jacket.
Embodiment
Below in conjunction with accompanying drawing, the utility model is explained in detail.
A kind of Ethernet unmasked iron fluorine cage foamed insulation six class horizontal symmetrical data cable as shown in Figure 1, comprise cable inner core and the outer jointing jacket 3 outside coated with cable inner core, the center-filled bar 1 that described cable inner core comprises at least two group twisted pair wires 2 and separated by two groups of twisted pair wires 2; Described center-filled bar 1 for foaming structure be cross, cable inner core is separated in four regions by described center-filled bar 1, and each intra-zone is provided with one group of twisted pair wire 2; Described outer jointing jacket 3 is made up of low cigarette polyvinyl chloride (LS-PVC) material; Often organize outside described twisted pair wire 2 and be provided with insulation protective jacket; Described insulation protective jacket is foaming structure.
The conductor twisting of every two coated insulation protective sleeves forms one group of twisted pair wire; twisted pair wire has more than two groups; two groups or three groups or four groups of twisted pair wires carry out twisting stranding by center-filled bar 1 with same pitch; the utility model is four groups; four groups of twisted pair wires 2 are placed on twisting stranding in criss-cross center-filled bar 4 marker spaces, outer outer jointing jacket 3 after stranding.Material is thus formed a novel foaming FEP for Ethernet insulation CMP flame retardant rating horizontal symmetrical data cable.
The cored wire conductor of twisted pair wire 2 of the present utility model is that the hypoxemia of 2.6mm or oxygen-free copper bar are made through wire drawing, annealing by diameter, and the wire gauge of conductor is the solid of 20 ~ 28AWG or stranded conductor; The insulation protective jacket of heart yearn is made up through chemical mode foaming of fluoroplastics (FEP) and fluorine plastic foam agent (FOAMFEP) material, foam degrees is (20 ~ 30) %, insulation protective jacket is foaming structure only, without inside and outside cortex, insulation protective jacket thickness is 0.17+/-0.02mm; Two heart yearns of twisted pair wire 2 are stranded shape, and the four pairs of lines all adopt the back twist technology of (20 ~ 60) %; Width is adopted to be 3.5+/-0.2mm between four pairs of twisted pair wires, thickness is that shim filled in the cross of 0.3+/-0.1mm, cross is filled and is made up through chemical mode foaming of fluoroplastics (FEP) and fluorine plastic foam agent (FOAMFEP) material, and foam degrees is (30 ~ 40) %; Outer jointing jacket 3 is made up of low cigarette polyvinyl chloride (LS-PVC) material, and the thickness of outer jointing jacket is 0.35+/-0.05mm, and finished product is round, and average wire diameter is at 5.6+/-0.3mm.
High-speed data communication paired cable of the present utility model has 4 important unit for electrical property parameters: impedance, decay, return loss, cross-talk etc., has 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.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.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 ± 15Ohm.
Decay is divided into conductor to decay and diectric attenuation two parts, and conductor decay is relevant with resistance, so adopt oxygen-free copper or hypoxemia copper product, makes resistance reach minimum; Insulation and packing material all select fluoroplastics (FEP) and fluorine plastic foam agent (FOAMFEP), it is all the smaller material of dielectric constant and dielectric loss angle, and employing foaming structure, 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 on the basis 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 the foam filled bar of uniqueness, 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 utility model is one of superior performance of this high-speed data communication paired cable keeping the raw material usage that the basis of high flame resistance effectively reduces cable, and insulation foaming Rotating fields can solve the problem of Insulation Material consumption effectively.Fill and adopt foaming structure, also the weight of product is effectively reduced when not affecting electric property and physical dimension, and filling also becomes more soft after foaming, thus make finished cable also become soft, also improve the damage-retardation performance of wire rod in Ethernet wiring system itself simultaneously.Lighter in weight, being easy to wiring, and saving this high cost material, 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.
