Abstract
The utility model discloses a data cable with a skeleton structure. The data cable comprises at least one cable wire core and an outer sheath wrapped round the cable wire core. The cable wire core comprises wires and an I-shaped cable skeleton. Every two wires are twisted to form a twisted pair wire. The twisted pair wires are embedded at two sides of the I-shaped cable skeleton in same amount and twisted by the I-shaped cable skeleton. Four protruding objects are disposed on four corners of the I-shaped cable skeleton. By above manner, crosstalk among line groups in signal transmission is reduced and signal transmission performance is increased.
Description
Technical field:
The utility model relates to the communications field, is specifically related to telecommunication cable.
Background technology:
The high speed development of information technology needs the network that speed is faster, capacity is larger to carry, and the transmission rate that the existing Class 6 cable that is widely used in wiring market can't satisfy every pair of line on the cable all reaches the 100m Distance Transmission of 2.5Gb/s, and bandwidth also only has 250MHz; Use the bandwidth minimum requirements of 10G technology to be 500MHz, and under such high frequency, noise jamming problem during wiring between the line group is difficult to solve by simple Digital Signal Processing, therefore the Class 6 cable of a kind of enhancement mode of needs design solves the performance under AXT problem and the assurance high frequency.
The utility model content:
For shortcoming of the prior art, the utility model purpose is to provide a kind of data cable with skeleton structure, and this data cable can reduce the cross-talk between the signal transmission center line group, improves signal transmission performance.
For achieving the above object, the technical scheme that the utility model provides is: a kind of data cable with skeleton structure, comprise at least one cable core and the oversheath of coating cable core, described cable core is made of wire and cable skeleton, described cable skeleton is the I shape skeleton, described wire twists into one group of twisted pair wire in twos, the both sides of the described I shape skeleton of embedding that described twisted pair wire is equal in number also twist together by the I shape skeleton, and four jiaos on described I shape skeleton is with four projections.
Preferably, the length of described projection is between 0.2mm--0.8mm.
Further, the material of described I shape skeleton is polyethylene.
Further, described twisted pair wire is even number.
Further, described jacket material is polyvinyl chloride or low smoke and zero halogen material.
Further, described cable core number is 4 or 7.
I shape skeleton described in the utility model can adopt polyethylene or the low tangent consumable material of other low-k to make.
The projection that I shape skeleton described in the utility model is four jiaos plays the effect that increases air dielectric, crosstalking between each cable core of establishment and between each twisted pair wire.The projection that the I shape skeleton is four jiaos also makes the spacing of cable core and oversheath increase, and the effective dielectric constant of cable is reduced, and the transmission performance that is beneficial to cable improves.
Jacket material can adopt the larger polyvinyl chloride of hardness, low smoke and zero halogen material or other cable sheath materials in the utility model, and thickness and the outside diameter of cable can be adjusted according to cable performance and standard-required.
In the utility model in every cable core the number of twisted pair wire can determine according to actual needs a pair of or two pairs, the width of I shape skeleton is also adjusted according to the number of embedded twisted pair wire.
In the data cable described in the utility model, cable core can be determined 4 or 7 or other quantity according to actual needs.
By technique scheme, the beneficial effects of the utility model are: adopt four jiaos of I shape skeletons that projection arranged can reduce the cross-talk between the cable core and twisted pair wire in the signal transmission, improve signal transmission performance.
