Abstract
The utility model relates to the data cable technology field, especially relates to a cylindrical framework data cable. The data cable is composed of a sheath, a twisted pair wire, a central framework, an insulating layer, a copper conductor and a total shielding layer, and is characterized in that the central framework of the data cable is cylindrical, and the total shielding layer is arranged on the outside of a cable core. By using the cylindrical framework data cable of the utility model, the manufacturing length of the cylindrical framework is increased, higher crosstalk attenuation and return loss performances are achieved, the to-environment electromagnetic interferences are eliminated and reduced, the transfer impedance is reduced, the transmission performance is improved, the product softness is good, and the wiring construction is convenient.
Description
Technical field
The utility model relates to the data cable technical field, especially relates to a kind of data cable of cylindrical skeleton.
Background technology
Existing non-shielding six class data cables are made up of sheath, twisted pair wire and cross center framework, cross center framework factory length only has 2000 meters, increase a joint as surpassing 2000 meters palpuses, limited cross center framework factory length, increased the data cable manufacturing cost, cross center framework joint has reduced performances such as the crosstalk attenuation, return loss of cable, its performance can not satisfy existing high-quality communication needs, adopted central cross shape skeleton structure simultaneously, its transferred product impedance is higher, pliability is poor, cable wiring manufacture inconvenience.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of cylindrical bone rack data cable, has increased cylindrical skeleton factory length, has improved data cable crosstalk attenuation, return loss performance, and the product pliability is good, and wiring is convenient.
In order to address the above problem, technical solutions of the utility model are: a kind of cylindrical bone rack data cable, by sheath (1), twisted pair wire (2), center framework (3), insulating barrier (4), copper conductor (5) and total screen (6) are formed, it is characterized in that: be provided with the total screen of single face clad aluminum foil (6) in the described sheath (1), in the total screen of single face clad aluminum foil (6), be provided with 4 pairs of twisted pair wires (2), in the middle of 4 pairs of twisted pair wires (2), be provided with center framework (3), twisted pair wire (2) is by outer two stranded the forming of cable conductor that are surrounded by solid insulating barrier (4) of solid copper conductor (5), and described center framework (3) is cylindrical.
The beneficial effects of the utility model: the center framework factory length has increased by 9 times, is increased to 20000 meters from existing 2000 meters; Same length center framework joint has reduced 9, must there be a joint to change into 20000 meters from existing 2000 meters center frameworks a joint is only arranged, the center framework raw material reduce 70%, have reduced production cost, have improved economic benefit, product has reached higher crosstalk attenuation, return loss performance, eliminate and the interference of minimizing environment electromagnetics, reduced transfger impedance, improved transmission performance, the product pliability is good, and cable wiring manufacture is convenient.
