Description
Technical field
The invention belongs to cable apparatus technical field, particularly relate to the Symmetric Composite structure of a kind of hypomegetic parallel high-speed transmission cable.
Background technology
Presently used cable is generally symmetrical paired cable, and 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 subject to the restriction of itself structure, the most high-transmission frequency of theory 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 symmetrical paired cable deforms simultaneously, thus causing that 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 the transmission frequency reaching 1GHz, it is necessary to meet larger-diameter conductor, causes that 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 is 1 pair or 2 pairs, and conductor specification external diameter is all bigger, but 1 pair or 2 pairs of Parallel Symmetric shaft cable subject matters are that transmission channel is few, transmission frequency is not high, is typically in below 6GHz, it is difficult to meet multilink data transmission and bending radius is also affected by considerable restraint.And skin foam skin PE insulating inner injects gas, PE material hardness is low, in subsequent handling, it is easy to causing deformation, product structure dimensional uniformity is bad, and performance is bad.
Summary of the invention
It is an object of the invention 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 wire diameter, decreases space hold, strengthens air flowing, it is prone to heat radiation, material consumption is less, and cost is low, more environmental protection, improve transmission frequency, reach 25GHz and more than；Wire rod is made to use in rugged environment condition more and small-bend radius occasion；Improve the Symmetric Composite structure of the hypomegetic parallel high-speed transmission cable of transmission stability, its technical scheme is as follows:
The Symmetric Composite structure of hypomegetic parallel high-speed transmission cable, it is characterized in that, the Symmetric Composite structure of 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 place composition line pair through parallel, and line is externally through the vertical bag of metal forming and the polyester belt individually shielded layer of wrapped formation.
Optimal way is, quantity is 2-8 pair by described axis of symmetry heart yearn.
Optimal way is, described some cross sections to axis of symmetry heart yearn form circle.
The Symmetric Composite structure of hypomegetic parallel high-speed transmission cable provided by the invention, 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 rugged environment condition more and small-bend radius occasion.Axis of symmetry heart yearn, to combination and screen layer, improves transmission frequency and transmission stability.
The invention has the beneficial effects as follows: reduce buying cost and use cost, and general data center these series products in a large number, the form of tying up is routed in machine room, little wire diameter, decrease space hold, strengthening air flowing, it is easy to heat radiation, material consumption is less, cost is low, more environmental protection, improve transmission frequency, reach 25GHz and more than；Wire rod is made to use in rugged environment condition more and small-bend radius occasion；Improve transmission stability.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic of hypomegetic parallel high-speed transmission cable.
Detailed description of the invention
Embodiment is illustrated below in conjunction with Fig. 1:
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 place composition line pair with a ground wire 3 through parallel, and line is externally through the vertical bag of metal forming and the individually shielded layer 5 of the wrapped formation of polyester belt；Some to axis of symmetry heart yearn pair outside around metal-clad 6, finally then 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, quantity is 2-8 pair by described axis of symmetry heart yearn.
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, being configured to of each heart yearn pair: every center conductor squeezes and covers fluoroplastics and form, 2 center conductors place composition line pair through parallel, 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, finally then 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.
