Description
Technical field
This utility model belongs to cable apparatus technical field, particularly relates to a kind of hypomegetic parallel high-speed transmission cable.
Background technology
The most symmetrical paired cable of presently used cable, symmetrical paired cable structure is generally 8 heart yearns, and every 2 heart yearns are through symmetrical 4 groups of lines pair of stranded formation.Symmetrical paired cable is limited by itself structure, theory high-transmission frequency is at 1.2GHz, actual from the manufacture of product, the transmission frequency surpassing seven class symmetry paired cables at present is 1GHz, the External Force Acting that is easily subject in construction of the most symmetrical paired cable deforms, thus cause line, to when transmitting high-frequency signal, nonsynchronous phenomenon occurs, cause the problems such as loss and delay that signal transmits.This structure cable wants to reach the transmission frequency of 1GHz, it is necessary to meet larger-diameter conductor, causes the finished product external diameter also can be very big, and some little space situations use extremely inconvenient.
The development of Parallel Symmetric shaft cable originates in recent years, position up till now, its major product structure be 1 to or 2 right, and conductor specification external diameter is all bigger, but 1 to or 2 pairs of Parallel Symmetric shaft cable subject matters be that transmission channel is few, transmission frequency is the highest, typically at below 6GHz, it is difficult to meet multilink data transmission and bending radius is also very limited.And skin foam skin PE insulating inner injects gas, PE material hardness is low, in subsequent handling, easily causes deformation, and product structure dimensional uniformity is bad, and performance is bad.
Summary of the invention
The purpose of this utility model is to solve techniques discussed above problem, it is provided that one reduces buying cost and use cost, and general data center is with these series products a large amount of, the form of tying up is routed in machine room, little line footpath, decreases space hold, strengthen air flowing, it is easy to heat radiation
Material consumption is less, and low cost is more environmentally friendly, improves transmission frequency, reach 25GHz and more than；Wire rod is made to use in more rugged environment condition and small-bend radius occasion；Improve the hypomegetic parallel high-speed transmission cable of transmission stability, its technical scheme is as follows:
A kind of hypomegetic parallel high-speed transmission cable, it is characterized in that, described hypomegetic parallel high-speed transmission cable includes some to axis of symmetry heart yearn pair, every pair of axis of symmetry heart yearn is to including two center conductors and a ground wire, the outside of every center conductor is squeezed and is covered fluoroplastics, two center conductors and a ground wire are through being placed in parallel composition line pair, and line is externally through the vertical bag of metal forming and the polyester belt individually shielded layer of wrapped formation；Some to axis of symmetry heart yearn pair outside around metal-clad, the most again through metal wire knitted gauze screen, form total cable core, outside total cable core squeeze cover PVC or non-halogen material plastic sheath.
Optimal way is, described axis of symmetry heart yearn is 2-8 pair to quantity.
Optimal way is, described some cross sections to axis of symmetry heart yearn form circle.
The hypomegetic parallel high-speed transmission cable that this utility model provides, when in use, fluoroplastics can ensure that the concordance of insulation is higher, solid FEP insulate, and internal without gas injection, FEP material hardness is high, energy anti-deformation in following process, product structure dimensional uniformity is good, stable performance, makes wire rod use in more rugged environment condition and small-bend radius occasion.Axis of symmetry heart yearn, to combination and screen layer, the combination of total cable core and shielding construction thereof, defines multilayer screen mechanism, improves transmission frequency and transmission stability.
The beneficial effects of the utility model are: reduce buying cost and use cost, and general data center is with these series products a large amount of, and the form of tying up is routed in machine room, little line footpath, decreases space hold, strengthens air flowing, it is easy to heat radiation,
Material consumption is less, and low cost is more environmentally friendly, improves transmission frequency, reach 25GHz and more than；Wire rod is made to use in more rugged environment condition and small-bend radius occasion；Improve transmission stability.
Accompanying drawing explanation
Fig. 1 is cross-sectional schematic of the present utility model.
Detailed description of the invention
Below in conjunction with Fig. 1 specific illustrative embodiment:
A kind of hypomegetic parallel high-speed transmission cable, described hypomegetic parallel high-speed transmission cable include some to axis of symmetry heart yearn to 1, every pair of axis of symmetry heart yearn includes two center conductors 2 and a ground wire 3 to 1, the outside of every center conductor 2 is squeezed and is covered fluoroplastics 4, two center conductors 2 and a ground wire 3 are through being placed in parallel composition line pair, and line is externally through the vertical bag of metal forming and the polyester belt individually shielded layer of wrapped formation 5；Some to axis of symmetry heart yearn pair outside around metal-clad 6, the most again through metal wire knitted gauze screen 7, form total cable core, outside total cable core squeeze cover PVC or non-halogen material plastic sheath 8.
Optimal way is, described axis of symmetry heart yearn is 2-8 pair to quantity.
Optimal way is, described some cross sections to axis of symmetry heart yearn form circle.
With the naked copper of 0.08-0.38mm, alloyed copper, coating copper, the extrusion insulation of coating alloy copper conductor, requirement and adverse circumstances in order to reach electric property normally use, Insulation Material uses fluoroplastics FEP, PFA, ETFE, 2-8 is set to Parallel Symmetric shaft core line pair in cable, each heart yearn is to being configured to: every center conductor squeezes and covers fluoroplastics and form, 2 center conductors are through being placed in parallel composition line pair, line externally indulges, through metal forming, the heart yearn pair that bag is individually shielded with the wrapped formation of polyester belt, so makes wire rod transmission frequency reach more than 25GHz.Multipair axis of symmetry heart yearn is to pressing circular (cross section) stranding, and in outside wrapped metal forming, the most again through metal wire knitted gauze screen, forms total cable core.Squeeze outside total cable core and cover PVC(or non-halogen material) plastic sheath, constitute cable finished product.
The equipment produced due to fluoroplastics is simple relative to the equipment of skin foam skin structure, failure rate is low, it is ensured that the concordance of insulation is higher, and solid FEP insulate, and internal without gas injection, FEP material hardness is high.Energy anti-deformation in following process, product structure dimensional uniformity is good, stable performance.
The design in little line footpath is that million dragons are pioneering in the application of this product, reduces buying cost and use cost, more environmentally friendly.Environmental angle: 1) data center's these series products in a large number, the form of tying up is routed in machine room, little line footpath, decreases space hold, strengthens air flowing, it is easy to heat radiation.2) material consumption is less, and low cost is more environmentally friendly.
