Specific embodiment
Embodying the utility model feature will describe in detail in the following description with the exemplary embodiment of advantage.It should be understood that
Be that the utility model can have various changes in different implementation methods, it does not all depart from model of the present utility model
Enclose, and explanation therein and diagram are treated as purposes of discussion in itself, and be not used to limit the utility model.
In order to further illustrate principle of the present utility model and structure, it is preferable to carry out to of the present utility model in conjunction with accompanying drawing
Example is described in detail.
Refering to Fig. 1, the coaxial cable 1 of the present embodiment includes the inner wire 11 for setting gradually from inside to outside, insulating barrier 12, answers
Close outer conductor layer 13 and restrictive coating 14.
Inner wire 11 is located at most the inside.The effect of inner wire 11 is transmission high-frequency signal.Inner wire 11 in the present embodiment
It is single silver-coated copper wire.
Insulating barrier 12 coats inner wire 11.In the present embodiment, insulating barrier 12 is that polytetrafluoroethylene (PTFE) pushing is formed, and plays branch
Support and the effect of insulation.Polytetrafluoroethylene (PTFE) has excellent high and low temperature resistance and chemical stability.
Compound outer conductor layer 13 includes braiding layer 131 and wicking layer 132.Braiding layer 131 includes the first braiding layer 133 and the
Two braiding layers 134.
First braiding layer 133 is coated on outside insulating barrier 12.Second braiding layer 134 is coated on outside the first braiding layer 133.
In the present embodiment, the first braiding layer 133 and the second braiding layer 134 are tinned wird braiding and form.Can avoid
Copper is aoxidized and corroded, and shield effectiveness is good.
In the present embodiment, the first braiding layer 133 is tinned wird braiding layer.Tinned wird is four strands, and per share described
The internal diameter of tinned wird is 0.10mm.Second braiding layer 134 is tinned wird braiding layer.Tinned wird is six strands, and per share institute
The internal diameter for stating tinned wird is 0.12mm.It is understood that as long as density >=98% of braiding layer 131 can be made, first weaves
The design of number of braided strand and internal diameter that layer 133 and the second braiding layer 134 are used is in the range of this patent.
Count >=98% of braiding layer 131.Count refers to that the surface covered by strands is produced with the whole cable that is braided
The ratio between product surface.When ratio is close to 1, braiding layer will be seamless.When ratio is less than 1, braiding layer will appear from the seam being evenly distributed
Gap.Ratio is bigger, then the width in gap is smaller, i.e., count is bigger.Count >=98% of braiding layer 131, it is ensured that braiding
The gap width of layer 131 is small, improves shield effectiveness.
Count >=98% of braiding layer 131, the i.e. gap width of braiding layer 131 is small, and the use of tin is saved in wicking
Amount.
First braiding layer 133 and the second braiding layer 134 have following effect：One has been the work for fastening inner wire and insulating barrier
With two has been shielding action.
The surface entirety wicking after the first braiding layer 133 and the second braiding layer 134 weave of wicking layer 132 is formed.That is wicking
Layer 132 all coats braiding layer 131.The thickness of wicking layer 132 is 0.05-0.1mm.
The effect of wicking layer 132：One is the jamproof shielding action of radiation proof, and two there is provided tin layers so that in welding
Shi Yinwei is to weld tin and electronic component, and the welding than non-tin metal and electronic component is easier in electronic component
Upper welding, improves operating efficiency.
Restrictive coating 14 is located at the outermost layer of coaxial cable.In the present embodiment, restrictive coating 14 uses polyolefin jacket.When strong
When adjusting fireproofing of cable security, low-smoke and halogen-free flame retardant polyolefin jacket should be used, low smoke halogen-free flame-retardant polyolefin has fire-retardant
Property, the characteristic such as low cigarette, Halogen, low corrosion, low toxicity.
Coaxial cable of the present utility model, as a result of tin layers so that coaxial cable of the present utility model is by tin silk
When welding, because being to weld tin and electronic component, than the welding of non-tin metal and electronic component, it is easier to
Welding is completed on electronic component, operating efficiency is improve.Welding can be just completed using a small amount of tin silk, reduction is welded into
This.
Coaxial cable of the present utility model, because compound outer conductor is again formed braiding layer entirety wicking using after braiding,
Wicking layer all coats braiding layer, you can all closed with by inner wire, realizes the shielding of outer conductor integral full-closed formula, obtains
Shielding properties high, reduces loss and interference free performance.
Although describing the utility model with reference to exemplary embodiment, it is to be understood that, term used be explanation and
Exemplary and nonrestrictive term.Because the utility model can be embodied without deviating from utility model in a variety of forms
It is spiritual or substantive, it should therefore be appreciated that above-mentioned implementation method is not limited to any foregoing details, and should be in appended claims
Widely explained in the spirit and scope for being limited, therefore the whole fallen into claim or its equivalent scope changes and retrofits
