The width of each framework piece gradually increases from the head end to the tail end. The widths of the cable framework pieces gradually increase from the head ends to the tail ends, and cost can be reduced to the maximum degree under the circumstance that supporting of the cable framework for twisted pairs is not influenced. The invention further discloses a mold for producing the cable framework.
Description
Technical field
The present invention relates to field of cable technology, particularly relate to cable frame and the mould for the production of this cable frame.
Background technology
Cable frame refers in cable for by spaced for the multipair twisted-pair feeder structure preventing crosstalk from supporting multipair twisted-pair feeder simultaneously.Common cable frame is crossing skeleton, and crossing skeleton refers to that skeleton entirety is in cross, is placed with twisted-pair feeder in four quadrants of crossing skeleton respectively.
But the shape of existing crossing skeleton is all crosss of very standard, be also the horizontal and vertical dividing plate full symmetric of crossing skeleton, thickness is also very even.But because twisted-pair feeder is generally circle, the contact point of crossing skeleton and twisted-pair feeder is less, as long as the support strength of the contact point of crossing skeleton and twisted-pair feeder is enough, then the thickness without the need to the horizontal and vertical dividing plate by crossing skeleton is unified.
Summary of the invention
Technical problem to be solved by this invention is, for the above-mentioned deficiency of prior art, proposes a kind of lower-cost cable frame.

Embodiment
Be below specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiments.
Cable frame of the present invention comprises multiple matrix tablets of common head end, and the space formed between adjacent matrix tablet is for holding twisted-pair feeder.Circular twisted-pair feeder contacts with adjacent matrix tablet respectively and is supported.Because circular twisted-pair feeder generally can not contact with matrix tablet head end, therefore the width of matrix tablet head end is without the need to the same with terminal end width, and in the present invention, the width of multiple matrix tablet increases gradually by head end terminad.
The longitudinal length of cable frame is usually consistent with the length of cable, is also that the longitudinal length of cable frame is generally much larger than its cross-sectional width.After a cross-sectional width reduction part for cable frame, a part of material of this reduction is amplified by cable frame longitudinal length, finally makes the overall materials of cable frame sharply reduce.
The matrix tablet number of cable frame of the present invention can be arbitrary number, such as can for being total to three matrix tablets of head end, four matrix tablets or five matrix tablets etc.
Multiple matrix tablet of the present invention can adopt identical structure also can adopt different structures, as long as the width of those matrix tablets is increased gradually by head end terminad.
In a preferred embodiment, in multiple matrix tablet, at least one matrix tablet terminal end width is different from other matrix tablet terminal end width.
Due to a certain matrix tablet terminal end width difference distance causing being supported between twisted-pair feeder on matrix tablet and adjacent twisted-pair feeder also become different.On the one hand, the change of the spacing of adjacent twisted-pair feeder can improve the function of cable inner near-end crosstalk attenuation; On the other hand when many cable winds together time, in many cables, the relative position of twisted-pair feeder changes, and how can significantly improve AXT defend degree.
When there is the larger matrix tablet of a terminal end width in matrix tablet, although inner proximal crosstalk attenuation and the AXT defend degree of cable can be improved, or the material of matrix tablet can be increased.For reducing matrix tablet material further, meeting under the prerequisite that the larger matrix tablet of this terminal end width supports twisted-pair feeder, fluting can formed to reduce terminal material at its end.
In a preferred embodiment, described fluting makes matrix tablet end form both wing portions, and described alar part terminal end width is roughly the same with matrix tablet head end width.Because alar part terminal end width is roughly the same with matrix tablet head end width, therefore this alar part is enough to support twisted-pair feeder placed thereon.
Technical scheme of the present invention is described in detail below in conjunction with specific embodiment:
Please refer to Fig. 1, Fig. 1 is the front projection view of cable frame in the present invention first preferred embodiment.In FIG, cable frame comprises the first matrix tablet 10, second matrix tablet 20 of common head end, the 3rd matrix tablet 30 and the 4th matrix tablet 40; The axis of described first matrix tablet and the second matrix tablet overlaps, and the axis of described 3rd matrix tablet and the 4th matrix tablet overlaps; Described first matrix tablet is vertical with the axis of the 4th matrix tablet with the 3rd matrix tablet with the axis of the second matrix tablet.
In the present embodiment, the first matrix tablet 10, second matrix tablet 20 and the 4th matrix tablet 40 have identical structure, and the terminal end width of the 3rd matrix tablet 30 is greater than other matrix tablet terminal end width.
Can imagine ground, also can be that the terminal end width of multiple matrix tablet is greater than other matrix tablet terminal end width, such as the first matrix tablet and the second matrix tablet terminal end width be greater than other matrix tablet terminal end width etc.
Offer V-shaped fluting 31 at the end of the 3rd matrix tablet 30, this V-shaped fluting 31 makes the 3rd matrix tablet 30 end form both wing portions 32.
In the present embodiment, described first matrix tablet 10, second matrix tablet 20, the 3rd matrix tablet 30 and the 4th matrix tablet 40 head end width are 0.3-0.5 millimeter; Described first matrix tablet 10, second matrix tablet 20 and the 4th matrix tablet 40 terminal end width are 0.8-1.2 millimeter; Described 3rd matrix tablet 30 terminal end width is 1.8-2.5 millimeter.
Described V-shaped 31 bottoms of slotting are roughly the same with the 3rd matrix tablet terminal end width apart from the distance of the 3rd matrix tablet head ends.Namely also V-shaped 31 bottoms of slotting also are 1.8-2.5 millimeter apart from the distance of the 3rd matrix tablet head ends.
The terminal end width of both wing portions 32 is also identical with matrix tablet head end width, is 0.3-0.5 millimeter.
It can be shaping preferably on the one hand for the cable frame adopting above-mentioned size to make, and it also can support twisted-pair feeder preferably on the other hand.
By the cable frame of the present embodiment compared with traditional cruciform skeleton, its materials can save more than 50%, and electric property more can significantly improve.
For checking is built-in with the transmission performance of the cable of the present embodiment cable frame, the cable being built-in with the present embodiment cable frame is carried out test comparison with the cable being built-in with traditional cross cable frame, test condition is: under the temperature conditions of 20+/-3 DEG C, test its performance under the vector network analyzer (model AgilentE5061B) bundled by 100 meters of cables at 6+1.Test result is as follows:
1, NEXT ((cable is inner) near-end crosstalk) test result (traditional cross cable frame)
Next[dB@100m]
Next[dB@100m](Continuation 1)
2, PSNEXT (Alien Next power) test result (traditional cross cable frame)
