Fig. 2 is the cross-sectional view of non-shielded cable in the utility model the second preferred embodiment.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
Please refer to Fig. 1, Fig. 1 is the cross-sectional view of non-shielded cable in the utility model the first preferred embodiment.In Fig. 1, non-shielded cable comprises sheath 100, is arranged at skeleton 200 and four twisted-pair feeders 300 in sheath.In the present embodiment, skeleton 200 consists of five supports (210,220,230,240,250), and an end points of five supports all contacts with sheath 100 inner surfaces, the common end points setting of another end points.
In the present embodiment, it is non-circular that the length difference of five supports makes the cross section of sheath.Cross section is that non-circular non-shielded cable is compared cross section and had the ability of better anti-outside cross-talk for circular non-shielded cable.Its reason is: non-circular or irregular cable is because the right relative position of the line in different cables changes, and the medium on this cross section is inhomogeneous, and the position of variation and inhomogeneous medium all can significantly improve the defend degree of crosstalking.
Continue referring to Fig. 1, in Fig. 1, the support of carrying twisted-pair feeder 300 is not if background technology sample is square crossing setting, between the support of carrying twisted-pair feeder 300, there is an angle value, thereby be that distance between capable of regulating inner twisted pairs 300 reaches the function that improves cable inner proximal crosstalk attenuation by adjusting this angle value.
In the present embodiment, on the one hand the cross section by sheath is set to non-circularly to improve the anti-outside cross-talk ability of cable, improves cable inner proximal crosstalk attenuation ability on the other hand by the angle of adjusting between internal stent; Inside and outside adjust simultaneously, work along both lines, greatly improved the transmission performance of cable.
Transmission performance for cable in checking the present embodiment, the cable transmission parameter of test the present embodiment, test condition is: under the temperature conditions of 20+/-3 ℃, and its performance of the lower test of vector network analyzer (model Agilent E5061B) by 100 meters of cables in 6+1 binding.
Test result is in Table one.
Table one
NEXT ((cable is inner) near-end crosstalk) test result
PSANEXT (outer portion near end crosstalk power and) test result
PSA ACR-F (outside wait the decay of level far-end crosstalk specific power and) test result
From above test result, the anti-non-shielded cable of energy force rate tradition of crosstalking of the non-shielded cable in the present embodiment is high, the non-shielded cable of the present embodiment can be used in the transmission network of super large data, for example, in 10,000,000,000 transmission networks.
In addition, in Fig. 1, five are configured to five containing cavities (110,120,130,140,150), in first to fourth containing cavity, be placed with twisted-pair feeder 300, and the 5th containing cavity 150 is cavity, this cavity makes the anti-cross-talk ability in the outside of cable and inner proximal crosstalk attenuation ability all improve simultaneously.Its reason is: owing to being provided with cavity in cable, when many cables are arranged together, the tight adjacent probability of twisted pair wire in adjacent cables reduces (part twisted pair wire can be relative with cavity), thereby the outside anti-cross-talk ability of cable is improved.The inner twisted pair wire of single cable, owing to being separated by cavity, improves inner proximal crosstalk attenuation.
Can imagine ground, in cavity, not necessarily fill air, also can fill the material that other dielectric constants are lower.Meanwhile, number of cavities is more, and its improvement to the anti-outside cross-talk of cable and inner proximal crosstalk attenuation is better, can determine the quantity of cavity and the quantity of support by taking into account cost, withstand voltage properties and cable transmission performance.
In order to reduce costs, in the present embodiment, the support of cavity periphery (210,220) thinner thickness simultaneously again in order to strengthen cable voltage endurance capability, is also provided with stiffener 400 on support 220.The quantity of this stiffener 400 can be many.Certainly, if when the application scenario of cable does not need cable to have voltage endurance capability, this stiffener 400 can be set.
Preferably, in five containing cavities (110,120,130,140,150), at least one containing cavity, be also provided with and tear rope 500 so that cable is ripped.
Please refer to Fig. 2, Fig. 2 is the cross-sectional view of non-shielded cable in the utility model the second preferred embodiment.
In Fig. 2, skeleton 200 consists of six roots of sensation support (201,202,203,204,205,206), make cable there are six containing cavities (101,102,103,104,105,106), in six containing cavities, wherein in three containing cavities (101,103,105), be placed with twisted-pair feeder 300, other three containing cavities are cavity.
Six roots of sensation stent length is all not identical, and adjacent stent angulation is also different.
Different from the first preferred embodiment, in the present embodiment, stiffener is not set in cavity.
In addition, in the present embodiment, the end points of six roots of sensation support contacts with jacket inner surface, and the not end points setting altogether of another end points.Contrary, the end points of six roots of sensation support connects by intercell connector 600.
In the present embodiment, the spacing between twisted-pair feeder 300 is larger, and when many cables are arranged together, the probability that the twisted-pair feeder of different cables is oppositely arranged (only separate and have 2 layers of sheath) is lower, and cable transmission performance is better.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
