Abstract
The utility model provides a data transmission cable which is characterized in that 32 pairs of data lines are coated in polyester membrane, and a protection sleeve is arranged outside of the polyester membrane. The 32 pairs of data lines are divided into four module groups each of which has eight pairs of data lines. All module groups are wrapped and wound by different color bands so as to easily identify and connect the core lines. Besides, the 32 pairs of data lines are provided with 16 different twisting pitch to reduce crosstalk interference. A filled rope is added to the cable centre so that the interaction position between the groups remains relative stable to reduce the varying input impedance of the cable. The utility model has the advantages of simple structure and easy manufacture.
Description
Technical field
The utility model relates to the cable that a kind of information is transmitted, especially a kind of data cable.
Background technology
Along with developing rapidly of digitizing technique, data cable generally is used for railway, computer network, enterprise automation equipment, broadband network etc.Known 32 pairs of cables are usually used in the digital local exchange installation field, and its structure is: be coated with 32 pairs of data wires in the polyester film, polyester film is outward an oversheath.Though the transmission cable of this structure can be finished general data passes, because each of cable to data wire displacement takes place easily, cause that conductor mutual alignment spacing changes, thereby the variation, the signal of telecommunication transmission that influence cable input impedance are unstable; Regular meeting's crosstalk phenomenon influenced stability and accuracy that final data information is transmitted when this external cause pitch was provided with improper going back.
Summary of the invention
A kind of structure is stable more, the better data cable of performance for the technical problem that exists in the solution known technology provides for the utility model.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of data cable, per two twist together many that comprise polyester film, are coated in the polyester film have sheath outward to data wire, polyester film, it is characterized in that: describedly many data wire is divided into four unit groups, each unit group is pricked outward around colour band, and cable center is added with the gasket for packing of anti-stop element group displacement.
The utility model can also adopt following technical measures:
Described many be 32 pairs of data wires to data wire, divide four unit groups, 8 pairs of data wires are arranged in each unit group.
Described 32 pairs of data wires are provided with 16 kinds of different twisting pitch.
Also can increase aluminum composite belt or metal knitted screen between described polyester film and the sheath.
Advantage and the good effect that the utlity model has are: because 32 pairs of data wires are divided into four unit groups, each unit group has 8 pairs of data wires, and the data wire of each unit group with different colour bands prick around, differentiation was very convenient when this connected cable; Other 32 pairs of data wires are provided with 16 kinds of different twisting pitch, can effectively prevent the signal cross-talk; Be added with gasket for packing in cable center, can effectively avoid the displacement of each unit group, reduce the fluctuation of input impedance; The utility model also has advantage simple in structure, that be easy to make in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, be coated with 32 pairs of mutual stranded data wires in the polyester film 3, conductor 1-1 mutual stranded form of data wire having insulating barrier 1-2 by two to 1.32 pairs of data wires are four unit groups to being divided into, and every unit group has 8 pairs of data wires.Four unit groups with the colour band 2 of different colours prick around, this makes cable be easier to distinguish when connecting, thereby reduces the wiring mistake.32 pairs of data wires also are provided with 16 kinds of different twisting pitch, and (scope is from 9～50mm).Such pitch setting can significantly reduce cross-talk, and the 1MHz cross-talk index of cable is reached more than the 59dB.Outside the polyester film 3 is sheath 4, is laid with tear line 6 in the oversheath 4.In order to prevent the displacement of each unit group, reduce impedance irregularity, be added with gasket for packing 5 in cable center.
The utility model can also increase aluminum composite belt or metal knitted screen between polyester film and sheath, to reduce the interference of external electromagnetic waves.The notebook data transmission cable also can adopt the data wire of other varying number right, as 8 pairs, 16 pairs, 64 equities, all belongs to the utility model protection range.
