Description

A kind of high transfer rate six class twisted-pair feeders
Technical field
The utility model relates to the twisted-pair feeder that a kind of network service is used, concrete is a kind of six class twisted-pair feeders.
Background technology
At present signal transmission is mainly take UTP twisted-pair feeder and optical fiber as main, wherein optical fiber is mainly used in the signal transmission of long distance, and short-range signal transmission is mainly UTP twisted-pair feeder, and twisted-pair feeder is mainly used in transportation simulator acoustic information, and in fact, twisted-pair feeder is equally applicable to the transmission of digital signal, particularly short-range communication, but in transmitting procedure, the decay of signal is large, and easily produce wave distortion, therefore, under very short distance and special electronics transmission technology condition, Double-strand transmission rate just can reach 100Mbps~155Mbps, existing six class twisted-pair feeders improve with having compared with five classes or super Category-5 twisted pair in structure significantly in shape, not only the diameter of cable is thicker, and increase the crossing skeleton of insulation, four pairs of lines of twisted-pair feeder are placed in respectively in four grooves of crossing skeleton, the crossing skeleton of cable central authorities is the anglec of rotation with the variation of length, four pairs of twisted-pair feeders are stuck in the groove of skeleton, keep the relative position of four pairs of twisted-pair feeders, improve equilibrium response and the crosstalk attenuation of cable.In addition, guarantee that the balanced structure of cable is not destroyed in installation process.Therefore, its bandwidth can extend to 250Mbps or higher, that signal energy is aggregated thing insulating material and absorbs and produce a mechanism of the loss of signal, this absorption meeting increases along with the mass penalty of insulating material, therefore, the thinner lighter insulating material of general use, as organic materials such as polyethylene, but, frivolous insulating material usually can be squeezed in conductor cores in stranded operating process, there is gross distortion, finally cause insulating material to decline at the thickness of extruding place, the impedance that two conductor cores are picked up is reduced, bring on the contrary the larger loss of signal, this has become to extend the limiting factor of Double-strand transmission distance, for example, when CCTV adopts twisted-pair feeder to carry out transmission of video, its transmission range is 1500m left and right to the maximum, and unstable properties.
Summary of the invention
Technical problem to be solved in the utility model, be exactly for the existing deficiency of prior art, and a kind of six class twisted-pair feeders with low loss, high transfer rate, transmission range far away are provided, this twisted-pair feeder can not only be under existing comprehensive wiring system condition, the signal transmission rate that can reach far above existing twisted-pair feeder is provided, also can meets the demand of video remote transmission simultaneously.
This programme is achieved by the following technical measures: these the novel high transfer rate providing six class twisted-pair feeders; include outer layer insulation sheath and primary insulation sheath, eight holding wires and center bearing bracket; wherein outer layer insulation sheath adopts mechanical strength material high, anti-zoned cracking resistance to make, and plays a protective role.Between outer layer insulation sheath and primary insulation sheath, be filled with silastic-layer, utilize the high flame retardant of silicon rubber to coordinate outer layer insulation sheath to play fire prevention and forewarning function, while being breaking out of fire, the temperature resistant grade of outer layer insulation sheath is low first softening, even be transformed into viscous state, thereby start associated warning device, and silastic-layer temperature resistant grade is high, can give certain rescue time.Primary insulation sheath is high-toughness material, is convenient to center bearing bracket and supports, and its thickness can be thinner than outer layer insulation sheath and play buffer action.Eight above-mentioned holding wire compositions are identical, be respectively from the outer to the inner foaming layer, resistance to compression layer and oxygen-free copper conductor cores, wherein foaming layer has the good less loss of signal of frivolous characteristic energy, and resistance to compression layer mechanical strength is high, not yielding, impedance between the conductor cores that can guarantee to be twisted together can be lower than a lower limit, in order to give full play to the effect of the minimizing loss of signal of foaming layer, the thickness of foaming layer is preferably greater than the thickness of resistance to compression layer, if to the requirement of performance higher than the requirement to easy and simple to handle, can also fixed insulation cover be set outward at mutual two stranded twisted-pair feeders, further reduce the loss of signal and improve protection effect.
Above-mentioned center bearing bracket is made up of internal layer PE support and outer elastomer layer, outer elastomer layer can be to setting up, in transportation twisted-pair feeder process, good cushioning effect is played in the deformation of the foaming layer of eight holding wires that the twisting external force that twisted-pair feeder is subject to causes, whole center bearing bracket cross section is four jiaos of stars, four drift angles of four jiaos of stars contact with primary insulation sheath, radially extend along twisted-pair feeder, by the inner space quartering of primary insulation sheath, every two of eight described holding wires are twisted into four pairs mutually, lay respectively in four spaces, the design of four jiaos of stars is more stable with respect to existing crux, more easily keep the balanced structure of eight holding wires.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing to having adopted the measure of the multiple minimizing loss of signal in this scheme, make a novel twisted-pair feeder that provides there is the advantages such as the loss of signal is low, transmission rate is high, long transmission distance, for after existing comprehensive wiring communication system, make system transmission rate maximum reach 10000Mbps, meanwhile, for the transmission of CCTV video and other control signals, obtained the maximum transmission distance of 2000 meters.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
