Embodiment
By particular specific embodiment explanation embodiments of the present invention, person skilled in the art scholar can understand other advantages of the present invention and effect easily by the disclosed content of this specification below.
Refer to Fig. 1,2.Notice, appended graphic the illustrated structure of this specification, ratio, size etc., all contents in order to coordinate specification to disclose only, understand and read for person skilled in the art scholar, not in order to limit the enforceable qualifications of the present invention, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, not affecting under effect that the present invention can produce and the object that can reach, all should still drop on disclosed technology contents and obtain in the scope that can contain.Simultaneously, in this specification, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, changing under technology contents, when being also considered as the enforceable category of the present invention without essence.
Specific embodiment one:
As shown in Figure 1, Figure 1 shows that antistatic metal forming plastics composite band cross sectional representation, comprise metal level 1 and the non-metallic layer 3 that contains antistatic material, metal level and the non-metallic layer that contains antistatic material bond by adhesive layer 2.Whole antistatic metal forming plastics composite band thickness 0.01mm.Metal level adopts copper metal.Non-metallic layer adopts polythene material.Adhesive layer adopts ethyl acetate.Antistatic material used is nitric acid dimethyl stearyl hydroxyethyl ammonium
,described antistatic material content is 6%.
Specific embodiment two:
As shown in Figure 2, Figure 2 shows that the cross sectional representation that 10G Ethernet shadow data communication symmetrical cable is example, comprise metal level 1 and non-metallic layer 3, metal level 1 and non-metallic layer 3 bond by adhesive layer 2, are provided with one deck antistatic layer 4 at non-metallic layer 3 outer surfaces.Whole antistatic metal forming plastics composite band thickness 0.2mm.Metal level adopts aluminum metal.Non-metallic layer adopts polypropylene material.Adhesive layer adopts ethylene-methyl acrylate copolymer (EMAA).
High-speed data communication paired cable has cross-talk, electrostatic interference and the error rate between 6 important unit for electrical property parameters: Zu Kang ﹑ Shuai Jian ﹑ return losses, the interior cross-talk/group of group, has taken into full account six equilibrium in the time of design.
Impedance is parameter the most basic in electric property, and it determines apart from these three parameters of ﹑ insulative dielectric constant by the heart in conductor wire diameter ﹑ two conductors, 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 in the time of design, and conductor wire diameter is large, and low cut can be got well, but cost rising, final wire diameter is bigger than normal; The little decay of conductor wire diameter meeting is influenced.Considering while production the different and tension force of pitch, inconsistent can to produce each line different and affect impedance on two conductor centre-to-centre spacing, go out different insulation wire diameters according to different multiple twin pitch design, after guarantee finished product, the right resistance value of every line is controlled at 100 ± 15 Ohm left and right.
Decay is divided into conductor 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; Insulating material is selected high density polyethylene (HDPE) (HDPE) or physical blowing polyethylene (FOAM PE) material, is all the smaller material of dielectric constant and dielectric loss angle.
Return loss is subject to the impact of input impedance, due to load impedance do not mate 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 significantly sudden change of return loss.In design, adopt the pre-back twist technology of pair twist, eliminated the periodically impact of inconsistent generation on input impedance, improved the stability of input impedance, thereby optimized return loss.
When cross-talk designs in group, used the statistical method of Six Sigma experimental design to select best pitch, thereby met the requirement of crosstalking in group, real system can meet the qualified index of crosstalking of different levels.
One of performance that the antistatic metal forming plastics composite band of a kind of symmetrical data cable shielding use of the present invention is superior, is embodied in anti-static electricity interference and suppresses on error code.Traditional data communication paired cable design cannot solve due to triboelectrification and error code phenomenon between the insulator of bending or twisting generation.The present invention is broken through from shielding material, metal level and non-metallic layer are combined, and at the antistatic material of non-metallic layer surface-coated one deck, make whole metal forming plastics composite band there is antistatic behaviour, when can effectively eliminating wiring or using between line group because bending or twisting produce the noise jamming that electrostatic interference causes.Ethernet of the present invention had both met the mechanical performance of the TIA-568-C.2 of American Communications TIA and the requirement of electric property with symmetrical data cable, also meet the desired fire protecting performance in American insurance business laboratory (UL), have advantages of easy to use, be convenient to lay.So the present invention has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all can, under spirit of the present invention and category, modify or change above-described embodiment.Therefore, such as in affiliated technical field, have and conventionally know that the knowledgeable, not departing from all equivalence modifications that complete under disclosed spirit and technological thought or changing, must be contained by claim of the present invention.
