Embodiment
For further understanding feature of the present invention, technological means and the specific purposes that reached, function, the present invention is described in further detail below in conjunction with accompanying drawing and embodiment.
See also Fig. 1, cross type grid line 1 of the present invention comprises that an insulating sleeve 10, is located at isolation skeleton 20 and the four groups of twisted pair wires 30 in described insulating sleeve 10 inner chambers.
Please continue to consult Fig. 1, described isolation skeleton 20 is separated into four cavitys 40 with described insulating sleeve 10 inner chambers, and described four groups of twisted pair wires 30 are arranged at respectively in the described cavity 40.Described isolation skeleton 20 has one first obstruct section 21 and one and second obstruct section 22 that intersects of described first obstruct section 21.Described first obstruct section 21 is orthogonal and divide equally with described second obstruct section 22.The both ends of described first obstruct section 21 are provided with the two first relative stop parts 23, and the both ends of described second obstruct section 22 are provided with the two second relative stop parts 24.Described twisted pair wire 30 is resisted against the inboard of corresponding first stop part 23 or second stop part 24 respectively.
Please continue to consult Fig. 1, the cross section of described isolation skeleton 20 is a crux.The end of the end of two first stop parts, 23 cross sections and two second stop parts, 24 cross sections linked to each other successively can form a rhombus.In the present embodiment, the width of the cross section of described first stop part 23 diminishes from the inside to the outside successively.Described first stop part 23 near the face of insulating sleeves 10, with the two sides smooth connection of first stop part 23.Described second stop part 24 has a base portion 241 vertical with second obstruct section 22, an and extension 242 that is connected in the center of base portion 241.In the present embodiment, described extension 242 near the face of insulating sleeves 10, with the two sides smooth connection of described extension 242.In the present embodiment, described cross type grid line 1 is helical form and its cross section ovalize; The center of described cross type grid line 1 cross section is 2.50～3.00mm to the distance of the end of described first stop part 23, and the center of described cross type grid line 1 cross section to the distance of the end of described second stop part 24 is 3.75～4.25mm.
Please continue to consult Fig. 1, described twisted pair wire 30 is by two heart yearns, 31 stranded forming.Described heart yearn 31 comprises metallic conductor 311 and is wrapped in the insulating barrier 312 in metallic conductor 311 outsides.Because described cross type grid line 1 comprises four groups of twisted pair wires 30 altogether, described cross type grid line 1 has eight heart yearns 31 altogether.That the color of described eight heart yearns 31 is respectively is blue between blue, white, orange, green between orange, green, white between white, coffee, in vain between coffee.Described eight heart yearns 31 according to coffee between green between orange, green-Bai between blue between indigo plant-Bai, orange-Bai, coffee-Bai carry out four groups stranded, between described indigo plant-Bai between blue twisted pair wire 30 and green-Bai green twisted pair wire 30 be the diagonal angle setting.Between described indigo plant-Bai between blue twisted pair wire 30, orange-Bai between orange twisted pair wire 30, green-Bai between green twisted pair wire 30, coffee-Bai coffee twisted pair wire 30 in described insulating sleeve 10, be counterclockwise sequence arrangement.In the present embodiment, the described lay of respectively organizing twisted pair wire 30 is: coffee 8.50～9.50mm between green 9.00～10.00mm, coffee-Bai between orange 7.00～8.00mm, green-Bai between blue 10.00～11.00mm, orange-Bai between indigo plant-Bai.
See also Fig. 1 to Fig. 3, the stable of described heart yearn 31 structures is the key factor that influences network transmission performance.The present invention is fixed in described twisted pair wire 30 in the described cavity 40, and is resisted against the inboard of described first stop part 23 or second stop part 24, thereby described twisted pair wire 30 can well be fixed in the cavity 40 that described isolation skeleton 20 isolated.Since described first stop part 23 near the face of insulating sleeves 10, with the two sides smooth connection of first stop part 23; And described extension 242 near the face of insulating sleeves 10, with the two sides smooth connection of described extension 242, thereby the cross sectional shape that not only can keep grid line 1, and help keeping respectively organizing symmetric relation between the twisted pair wire 30, improved the structural stability of described heart yearn 31, reduce respectively to organize crosstalking between the twisted pair wire 30, and then make that the transmission performance of described cross type grid line 1 is promoted.Described cross type grid line 1 is helicoidal structure and its cross section ovalize, thereby has the space between line and the line, thereby adjacent cables interferes with each other when having significantly reduced wiring, i.e. the probability of alien cross-talk.And because the direction of rotation of adjacent cables is not quite similar, crosstalk, also increased the probability of cancelling out each other greatly even produce.What Fig. 2 and Fig. 3 showed is to test the pad value of described cross type grid line 1 gained and the curve chart of near-end cross value by network analyzer.By diagram as can be known, transmission frequency rises to present 500Mhz by the 250Mhz before improving, and has promptly been risen to the level of category 6+network 1 by the level of six class grid lines 1.Among Fig. 2 and Fig. 3, what described red line was represented is that normal data is an extreme value, and what described blue line was represented is measured value.As seen from the figure, all in normal data, the pad value and the near-end cross value of promptly described cross type grid line 1 have all reached requirement for the pad value of described cross type grid line 1 and the measured data of near-end cross value.Other numerical value such as return loss that described network analyzer is tested described cross type grid line 1 gained have also all reached requirement.Because the present invention only need replace to original cross mould the mould of making described isolation skeleton 20 and get final product, and need not add extra shielding construction, such as wire braid of aluminium foil or tin-coated copper etc., thereby not only reduced cost of manufacture greatly but also reduced production process, saved Production Time.
In sum, the present invention is fixed in described twisted pair wire 30 in the cavity 40 that described isolation skeleton 20 isolates, and described twisted pair wire 30 is resisted against the inboard of described first stop part 23 or second stop part 24, make the structure of described twisted pair wire 30 keep stable, thereby not only promoted the transmission performance of described cross type grid line 1, and reduced cost of manufacture.
The above embodiment has only expressed one embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as limitation of the scope of the invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with claims.
