Communication cable design.
Background technique
High-frequency radio frequency cable is mainly made of coaxial cable, it is by metal inside, dielectric support structure and outer metal layer
And sheath is constituted.Coaxial cable has the characteristics that decaying is small, standing wave is low, phase stabilization, is mainly used for high stability, high bandwidth
Radio communication in.High-performance coaxial cable is produced in enormous quantities in the U.S., European Union and Deng Guojunyou specialized factory, Russia, extensively
Applied in high-performance test equipment and weaponry.And China's high-end radio-frequency cable component almost all used at present according to
Rely import, therefore product is badly in need of realizing production domesticization and meeting the needs of each engineering.
Traditional high-frequency radio frequency cable is filled using perfect dielectric, and coaxial line, which is affected by temperature, to be easy to happen deformation and lead to phase
Position fluctuation, while it is also easy to happen deformation under external force, is not easy to restore after bending deformation.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of using cone structure, coaxial cable metal core and shell are protected
Filled media is less between set, and structure is more stable, and cable is as deformation caused by temperature change is more much smaller than common cable, phase
Position fluctuation is smaller, meanwhile, cable can preferably resile after deformation occurs under external force, to there is higher machinery
A kind of novel tapered stacked media structure radio-frequency telecommunication cable of intensity designs.
A kind of novel tapered stacked media structure radio-frequency telecommunication cable design of the invention, including radio frequency coaxial-cable gold
Belong to shell and metal core, between supported by cone cell polyimide plastic shell, be hollow, cone structure point among the cone structure
End side inside be provided with the consistent cylindrical hole of cable inner core diameter, bottom surface side is provided with biggish cylindrical hole；Tip size is small
In the cylindrical hole that bottom surface is opened, so as to make the tip of multiple cone structures placed in the same direction successively cover insertion bottom surface cylindrical hole
In；For single cone structure, the inner cylinder bore dia of tip one end, in this way can be with as the metal core of its coaxial cable
Being tightly placed on metal core facilitates metal core to fix, and prevent causes bracket to loosen since individual cone structure intermediate space is excessive becomes
The problem of shape, the inner cylinder bore dia of cone structure bottom end one end are greater than the diameter at tip, and cylindrical hole has circular cone half the height
The depth of degree, it can be ensured that mutually isostructural cone structure can be inserted into cylindrical hole in the same direction, realize stable nesting.
A kind of novel tapered stacked media structure radio-frequency telecommunication cable design of the invention, coaxial cable metal shell and electricity
Gap between cable metal core cone structure stacks fixed filling, and material is high molecular polyether imines, above and below cone structure
It is nested and is fixed on cable metal core by cylindrical hole in the same direction, so as to robust metal core position.
Compared with prior art the invention has the benefit that by above-mentioned setting, the present invention uses the macromolecule of cone cell
Polyimide plastics are as the bracket between the inner conductor of the coaxial cable metal core and metal shell sheath, cone structure inner tip
Side, which is provided with, is provided with biggish hole with the consistent hole of cable inner core diameter, bottom surface side, and cone cell bracket is covered at same direction in electricity
It on cable inner core and has supported outer metal layer and sheath, has been advantageous in that using this structure using cone structure, coaxial cable
Filled media is less between metal core and shell sheath, and structure is more stable, and cable is as deformation caused by temperature change is than general
Energization cable is much smaller, phase fluctuation is smaller；Meanwhile cable can preferably resile after deformation occurs under external force,
To there is higher mechanical strength.
Detailed description of the invention
Fig. 1 is cone cell coaxial line structure figure of the invention；
Fig. 2 is cone cell coaxial line top view of the invention；
