Description
The application is that name is called: a kind of high-speed data cable, application number be: 201310164317.4, the applying date is: the divisional application of the application for a patent for invention of on 05 08th, 2013.
Technical field
The invention belongs to technical field of cables, especially relate to the cable of a kind of high-speed transfer high-frequency data.
Background technology
Wires and cables industry is the domestic second largest industry being only second to automobile industry, and product variety Service Efficiency and domestic market occupation rate are all more than 90%.Worldwide, China is in electric wire, it has also become production the biggest in the world and country of consumption.
Along with the fast development of digitizing technique, computer is not only applied in various industrial plants in large quantities, and obtains more popularizing widely in all kinds of offices even residential building.The continuous expansion of computer network, extension, and transmit sharply increasing of quantity of information, make on the one hand to arrange net and use data cable consumption incremental with bigger amplitude;On the other hand require that again data cable has higher transmission speed, broader transmission bandwidth, with realize information quick, accurately transmit.Its transmission speed scope also develops from lOMbps to 10000Mbps, and it is contemplated that increasing due to the traffic, network speed will substantially exceed 1000Mbps in the near future, and this is provided that, with regard to an urgent demand people, the data cable that a kind of electric property is more excellent.
The parameter affecting high-frequency data high-speed transfer performance mainly has three below: impedance, decay and cross-talk.The external diameter stability of ormal conductor self, the dielectric constant of conductor adjacent material, the characteristic of conductor itself, unit length line centering insulation cabling quantity and torque etc. all can affect impedance.Decay is depended on surrounding the dielectric constant of conductor insulation material, the impedance of conductor and diameter, the line mutual alignment spacing etc. to structure, conductor.Cross-talk represents signal energy loss or to coupling the dissipation caused between line group, and the increase along with frequency is become a serious problem by cross-talk.Cross-talk is the key factor affecting signal high-speed transfer.For essence, the essence of cross-talk is that electromagnetic coupled is formed and interferes, electromagnetic coupled can be divided into two big classes, the first kind is called randomness electromagnetic coupled, the all accidentalia such as the defect being primarily due in the inhomogeneities of cable construction elements (such as wire, insulating barrier), the unsymmetry of structure and technique forming this kind of coupling cause, and this kind of coupling can reduce by regulating and controlling raw material and structural detail allowable deviation.Another kind of electromagnetic coupled is then called systematicness coupling, because being the interactive interference owing to causing between conductor, to factors such as the physical distances between line group, it is decided by the mutual alignment between conductor circuit to a great extent, as to line group spacing constant, to steady statue of line group position etc..Current data cable has generally comprised some to line group, and the high-speed data cable of standard is mostly utilize four unmasked strand cable to line group structure, it is by eight insulation core wires, it is twisted into four pairs between two equably to line group, again line group is combined stranding by this four couple, finally squeeze into oversheath and make finished cable.The relative position between line group is only fixed by cable jacket in this cable, but when cable laying tractive, bending, the construction of cable self creates drawing-off squeezing action, the relative position of line group can be subjected to displacement and change by it, even in cable knitting cycle, its structural parameters also can change.In addition, the fixing deflation effect of cable jacket, that can cause line group is mutually nested, makes an insulation core wire in a pair line group invade another in the circumscribed circle space of line group, and to the displacement of line group or nesting, can cause again and line group spatial joint clearance is diminished or can not get rational guarantee.In a word, the instability of the construction of cable, inevitably result in the deterioration of the performance indications such as such as input impedance, near-end crosstalk, FEXT and decay, seriously govern the raising of data cable operating frequency and data transmission bauds.
In order to improve the transmission performance of available data cable, Chinese patent application (application number 99805867.X) discloses a kind of data cable with crossing skeleton, this crossing skeleton have four protruding and for solid protruding dividing plate, space in oversheath is divided into four area of space held line group by four solid projection dividing plates, each region is equipped with a pair line group, so that line group keeps fixed position by cable core each other, what also effectively prevent line group is mutually nested simultaneously, and to line group surrounding space gap, there is certain Stabilization.But, the high-speed data cable in actually used does not require nothing more than has fixing position and stable spatial joint clearance to line group, so that cross-talk is minimized or is eliminated；Also require that data cable should be firm, pliable and tough and easy installation.And have crossing skeleton to line group data cable, owing to skeleton cross section being projected with cross protruding dividing plate, make skeleton cross section any on be respectively provided with higher bending resistance.The transverse property that this is additional, be also people is not intended to need, exactly makes data cable become stiff and very difficult bending, particularly particularly true in small angle tower radius situation, brings great difficulty to the mounting and installation of cable.This, for needing to adapt to the various data cable laying trend, is actually a very fatal defect.Again owing to there is size disparity between crossing skeleton external diameter and cable jacket internal diameter, the positioning performance causing crossing skeleton is not enough, easily make skeleton that displacement radially and play occur in oversheath, cause that space size shared by each pair of line group differs or change at random, cause the extruding that line group is additional and drawing-off.These cause the factor of only small geometric position or change of shape, all will result in the sharply decline of high-speed data cable performance.Due also to crossing skeleton adopts solid construction, this solid skeleton has higher dielectric constant, is unfavorable for, to the reduction of capacitance between line group, also govern the further raising to electric properties such as line group impedance, decay.
Chinese patent (application number 200420054577.2) discloses high-speed data cable, adopt every rib by upper and lower two pairs of line groups separately, but equally exist the intrusion problem of cable adjacent lines pair upon bending, and above between two pairs and actually also as easy as rolling off a log between two pairs below cause position to move, therefore, greatly have impact on the transmission of high speed signal.
Chinese patent (patent No. is 201120319957.4) discloses ten thousand megabits of high-speed data cable structures, and it is to adopt plastic-aluminum combined layer to be coated on copper conductor to realization external with drain wire, its purpose is to improve buffer capacity and improve insulating properties.Plastic-aluminum combined layer internal layer is mylar, outer layer is aluminum film layer, and the second insulating barrier is coated on outside aluminum film layer, and the second insulating barrier is bonding by PUR with aluminum film layer, this mode, and speed of production is slow and overall dimensions is wayward.
