Description
The application is that name is called: a kind of high-speed data cable, application number are: 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 a kind of cable 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, in electric wire, has become Production and consumption state the biggest in the world.
Along with the fast development of digitizing technique, computer is not only applied in various industrial plants in large quantities, and obtains popularizing more widely in all kinds of office even residential building.The continuous expansion of computer network, extension, and the sharply increase of transmission information amount, on the one hand making to arrange net increases progressively with larger amplitude with data cable consumption; On the other hand require that again data cable has higher transmission speed, wider transmission bandwidth, with realize information quick, accurately transmit.Its transmission speed scope also develops from lOMbps to 10000Mbps, and it is increasing to predict due to the traffic, network speed will substantially exceed 1000Mbps in the near future, this data cable that a kind of electric property can be provided more excellent with regard to an urgent demand people.
The parameter affecting high-frequency data high-speed transfer performance mainly contains following three: impedance, decay and cross-talk.Characteristic, the insulation of unit length line centering cabling quantity and the torque etc. of the external diameter stability of ormal conductor self, the dielectric constant of conductor adjacent material, conductor itself all can affect impedance.Decay is depended on and is surrounded the dielectric constant of conductor insulation material, the impedance of conductor and diameter, line to the mutual alignment spacing etc. of structure, conductor.Cross-talk represents signal energy loss or to the dissipation caused that is coupled between line group, the increase along with frequency is become a serious problem by cross-talk.Cross-talk is the key factor affecting signal high-speed transfer.With regard to essence, the essence of cross-talk is that electromagnetic coupled forms mutual interference, electromagnetic coupled can be divided into two large classes, the first kind is called randomness electromagnetic coupled, the main cause forming this kind of coupling is because all accidentalia such as the defect in the inhomogeneities of cable construction elements (as wire, insulating barrier), the asymmetry of structure and technique cause, and this kind of coupling can be reduced by regulation and control raw material and structural detail allowable deviation.Another kind of electromagnetic coupled is then called systematicness coupling, because be 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 stable state 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 to the unmasked strand cable of line group structure, it is by eight insulation core wires, be twisted into four between two equably to line group, again this four couple is combined stranding to line group, finally squeeze into oversheath and make finished cable.The relative position between line group is only fixed by cable jacket in this cable, but cable laying tractive, bending time, the construction of cable self creates drawing-off squeezing action, it can be subjected to displacement and change the relative position of line group, 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 the displacement or nested to line group, can cause again and line group spatial joint clearance diminished or can not get rational guarantee.In a word, the instability of the construction of cable, will inevitably cause the deterioration of the performance index such as such as input impedance, near-end crosstalk, far-end crosstalk 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 be solid protruding dividing plate, space in oversheath is divided into four area of space held line group by four solid projection dividing plates, a pair line group is equipped with in each region, thus make to keep fixed position each other to line group in cable core, 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 actual use not only requires to have fixing position and stable spatial joint clearance to line group, reduces to minimum to make cross-talk 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 all there is higher bending resistance.This is additional, be also the transverse property that people do not want to need, exactly make data cable become stiff and very difficult and bend, particularly in small angle tower radius situation particularly so, bring great difficulty to the mounting and installation of cable.This is 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, cause the positioning performance of crossing skeleton not enough, easily make skeleton that radial displacement and play occur in oversheath, cause space size shared by each pair of line group to differ or change at random, cause the additional extruding of line group and drawing-off.These cause the factor of very little geometric position or change of shape, all will cause the sharply decline of high-speed data cable performance.Also because crossing skeleton adopts solid construction, this solid skeleton has higher dielectric constant, is unfavorable for the reduction to capacitance between line group, also governs the further raising to electric properties such as the impedance of line group, 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 there is the cable intrusion problem that adjacent lines is right upon bending equally, and above two between and below two between in fact also very easily easily 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 megabit high-speed data cable structures, and it adopts plastic-aluminum combined layer to be coated on copper conductor to realization external with drain wire, its objective is to improve high buffer capacity and improving insulation property.Plastic-aluminum combined layer internal layer is polyester film, skin is aluminium film layer, and the second insulating barrier is coated on outside aluminium film layer, and it is bonding that the second insulating barrier and aluminium film layer pass through PUR, this mode, and speed of production is slow and overall dimension is wayward.
