Abstract
The utility model discloses a flexible radio frequency cable with a low loss and a highly stable phase, which comprises an inner conductor, an insulating layer, an outer conductor and a sheath layer which are sequentially and coaxially arranged from inside to outside, wherein the insulating layer is a porous polytetrafluoroethylene film with high degree of foamability and is wound on the surface of the inner conductor, and the outer conductor comprises a silver-plated copper belt layer, a silver-plated copper flat wire braid and a silver-plated single copper wire braid; the silver-plated copper belt layer is wound outside the insulating layer, and the silver-plated copper flat wire braid is wrapped on the outer surface of the silver-plated copper belt layer; and the silver-plated single copper wire braid is wrapped at the outer side of the silver-plated copper flat wire braid. The cable has the characteristics of reduced transmission attenuation, good bending flexibility and shielding performance, and stable phase, and can be used for the high-frequency telecommunication transmission process with highly stable phase requirements.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of radio frequency cable.
Background technology
In the existing telecommunication transmission manufacture process, high frequency electrical signal coaxial transmission cable primary structure generally is to adopt:
1, gas (PE) insulation+bare copper wire type of weave of single line inner wire+in midair;
2, twisted wire inner wire+gas (PE) insulation+silver-plated (tin) copper cash braiding in midair;
3, single line inner wire+real core (PTFE) insulation+silver-plated flat type copper wire braiding;
4, whole copper pipe semihard structure;
5, argon arc welding wrinkle copper pipe structure.
Its weak point is: because the needed frequency of utilization of field of telecommunications improves constantly at present, loss to cable requires more and more littler, shielding requirements is more and more higher, phase stabilization requires more and more higher, the structure of existing these high frequency coaxial transmission lines can't satisfy development need, and under huge temperature difference condition, general cable also can't satisfy the needs of operational environment.
The utility model content
The purpose of this utility model is in order to solve cable shield poor performance of the prior art, and the problem of phase stability difference provides a kind of low-loss height surely mutually soft radio frequency cable, makes its advantages of good shielding performance, the phase stability height.
For achieving the above object, the surely mutually soft radio frequency cable of the low-loss height that the utility model provides, comprise from inside to outside the inner wire of coaxial setting, insulating barrier, outer conductor and restrictive coating successively, described insulating barrier is a high foaming rate expanded microporous polytetra fluoroethylene-EPTEE film, and insulating barrier is wrapped in the inner wire surface; Described outer conductor comprises silver-plated copper belt, silver-plated copper lenticular wire braid and silver-plated single copper cash braid, described silver-plated copper belt is wrapped outside insulating barrier, silver-plated copper lenticular wire braid is coated on silver-plated copper belt outer surface, and silver-plated single copper cash braid is coated on the silver-plated copper lenticular wire braid outside.
In the utility model, insulating barrier, the silver-plated copper belt in the outer conductor that the high foaming rate expanded microporous polytetra fluoroethylene-EPTEE film on inner wire surface constitutes can adopt synchronous around-packing technology production, make that the displacement phase of cable is more stable, and properties of product are reliable; When variations in temperature, inner wire and expanded microporous polytetra fluoroethylene-EPTEE thin dielectric film temperature phase place are inversely proportional to, and the effect of mutual compensation is arranged, thereby make the whole cable phase stability good; The silver-plated copper belt is wrapped, make the flexibility of outer conductor relatively good, the double braid layer that silver-plated copper lenticular wire braid and silver-plated single copper cash braid are formed can strengthen the stability of the construction of cable, be convenient to the bending of cable, make cable more soft, the mechanical phase stability is better, and the braiding of multilayer simultaneously more makes whole cable shielding properties and interference free performance strengthen; It is little that this cable has transmission attenuation, and crooked flexibility is good, advantages of good shielding performance, and the characteristics of phase stabilization, the utility model can be used in the telecommunication transmission course of high steady requirement, high frequency mutually.
As improvement of the present utility model, described inner wire is some stranded silver-coated copper wires.Stranded silver-coated copper wire can be processed very softly, can guarantee cable tension, softness.
Under huge temperature difference condition, also can keep good bending property at cable for making, described restrictive coating adopts polyurethane material to make, this scheme has improved the stability of cable displacement and temperature phase place, and polyurethane material also can be processed cable surface bright and clean smooth easily.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 inner wire, 2 insulating barriers, 3 silver-plated copper belts, 4 silver-plated copper lenticular wire braids, 5 silver-plated single copper cash braids, 6 restrictive coatings.
Embodiment
As shown in Figure 1, be the surely mutually soft radio frequency cable of low-loss height, its structure is from inside to outside successively by the inner wire 1 of coaxial setting, insulating barrier 2, outer conductor and restrictive coating 6 are formed, inner wire 1 is made of some stranded silver-coated copper wires, insulating barrier 2 is a high foaming rate expanded microporous polytetra fluoroethylene-EPTEE film, insulating barrier 2 is wrapped in the surface of inner wire 1, outer conductor comprises silver-plated copper belt 3, silver-plated copper lenticular wire braid 4 and silver-plated single copper cash braid 5, silver-plated copper belt 3 is wrapped outside insulating barrier 2, silver-plated copper lenticular wire braid 4 is coated on the outer surface of silver-plated copper belt 3, silver-plated single copper cash braid 5 is coated on silver-plated copper lenticular wire braid 4 outsides, and restrictive coating 6 is made by polyurethane material.
The utility model is not limited to the foregoing description; those skilled in the art can also be on the basis departing from above-mentioned technological thought not; just can more be out of shape and revise technique scheme without performing creative labour, these distortion and revising all fall in the protection range of the present utility model.
