Abstract
The invention provides a semi-flexibility coaxial radio frequency cable, which comprises an inner conductor, an insulation layer and a weaving tin immersion layer from the inside to the outside. The inner conductor, the insulation layer and the weaving tin immersion layer are coaxial. The insulation layer is a polytetrafluoroethylene layer with a plurality of hole-shaped gaps inside, and a gas insulation medium is filled in the hole-shaped gaps. Compared with the prior art, the semi-flexibility coaxial radio frequency cable adopts the polytetrafluoroethylene as the insulation layer, the hole-shaped gaps are arranged inside the polytetrafluoroethylene and the gas insulation medium is filled inside the hole-shaped gaps, use of an expensive insulation material polytetrafluoroethylene is reduced, electric performance of the insulation layer is improved simultaneously, insulation performance is improved, transmission performance of the cable is further improved, cable size is reduced under the condition that same electric performance is retained, and production cost of the cable is greatly reduced.
Description
Technical field
The present invention relates to a kind of coaxial radio frequency cable, particularly relate to the half flexible coaxial radio frequency cable that is provided with poroid space in a kind of insulating barrier.
Background technology
At present, half flexible coaxial radio frequency cable on the market, its basic structure from inside to outside is made up of coaxial inner wire, insulating barrier, braid, wicking layer and restrictive coating successively, and wherein insulating barrier adopts solid the pushing of polytetrafluoroethylene to form.Because fluoroplastics cost an arm and a leg, though half flexible coaxial radio frequency cable of prior art can satisfy present instructions for use on performance, it adopts solid the pushing of fluoroplastics to have shortcomings such as production cost is high, transmission performance is low.Therefore be necessary to develop a kind of saving material in fact, reduce construction of cable size, the half flexible coaxial radio frequency cable that production cost is low and transmission performance is higher.
Summary of the invention
The object of the invention provides a kind of saving material, reduces construction of cable size, the low and half higher flexible coaxial radio frequency cable of same transmission performance of production cost.
For achieving the above object; The present invention provides a kind of half flexible coaxial radio frequency cable; Comprise coaxial inner wire, insulating barrier and braiding wicking layer from the inside to the outside successively; It is characterized in that: said insulating barrier is inner polytetrafluoroethylene floor with a plurality of poroid spaces, gassy dielectric in the said poroid space.
Preferably, the inner aperture, a plurality of poroid space of said polytetrafluoroethylene floor is identical.
Preferably, the edge, poroid space in the said polytetrafluoroethylene floor evenly is intervally arranged with the coaxial circumference of said inner wire.
Preferably, said gas-insulated medium is an air.
Preferably, said inner wire is the silver-plated copper conductor.
Preferably, said braiding wicking layer is a tinned copper wire braiding wicking layer.
Preferably, the braiding wicking layer of the present invention's half flexible coaxial radio frequency cable also comprises oversheath outward.The material of said oversheath is low smoke and zero halogen protective cover material, PVC (polyvinyl chloride) protective cover material, polyethylene sheath material or fluoroplastics protective cover material.
A kind of half flexible coaxial radio frequency cable provided by the invention is compared with the traditional cable that adopts the solid-core polyfluortetraethyleinsulating insulating layer, has the following advantages:
1. owing to, reduced the use of expensive insulating material polytetrafluoroethylene, compare the production cost that greatly reduces cable with traditional solid-core polyfluortetraethyleinsulating half gentle line in the poroid space of the set inside of teflon insulation layer;
2. through making poroid space when the inner wire extrapolation cohering tetrafluoroethene insulating barrier; And in poroid space, add air as dielectric; Improved the electric property of insulating barrier, its dielectric constant (ε=1.5～1.8) is compared with traditional solid-core polyfluortetraethyleinsulating insulating layer dielectric constant (ε=2.1) greatly and is reduced, and can improve the insulated electro performance greatly; Size keeping can reducing under the identical situation of electric property cable reduces whole cable cost greatly;
3. the inner poroid space of teflon insulation layer evenly is intervally arranged and guarantees the homogeneity of dielectric; Guarantee to keep when signal is propagated same wavelength in cable; Compare with traditional solid-core polyfluortetraethyleinsulating half gentle line,, improved transmission rate because insulating properties is improved; On same electrical transmission length, need shorter cable, saved the consumption of cable.
Description of drawings
Accompanying drawing 1 is the cross-sectional structure cutaway view of the present invention's half flexible coaxial radio frequency cable;
Wherein: 10, inner wire; 20, insulating barrier; 30, poroid space; 40, braiding wicking layer; 50, oversheath.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the present invention is elaborated.
See also Fig. 1; A kind of half flexible coaxial radio frequency cable provided by the invention; Comprise coaxial inner wire 10, insulating barrier 20, braiding wicking layer 40 and oversheath 50 from the inside to the outside successively, said insulating barrier 20 is inner polytetrafluoroethylene floor with a plurality of poroid spaces 30.
In present embodiment, said inner wire 10 is the silver-plated copper conductor.
In present embodiment; Said insulating barrier 20 constitutes for pushing polytetrafluoroethylene floor on the said silver-plated copper conductor; Said polytetrafluoroethylene floor push process within it portion prepare identical poroid space 30, a plurality of apertures; And said poroid space 30 evenly is intervally arranged along said inner wire 10 coaxial circumference, is full of air as dielectric in the said poroid space 30.The aperture in said poroid space 30 is looked the thickness of insulating barrier 20 and is decided.
In present embodiment, wicking forms said braiding wicking layer 40 outside the back for tinned copper wire weaves on said insulating barrier 20.
