Background technology
Current communication and development of electronic technology are more and swifter and more violent, and the demand of signal transmission with radio frequency coaxial-cable also strengthened day by day, and the cable shield litzendraht wire generally adopts copper cash, and the copper valency is high now, and the manufacturing cost of enterprise is increased.Therefore, how under the prerequisite that does not reduce the every electric property of radio frequency coaxial-cable, to optimize product structure, enhance productivity, to reduce production costs, become industry problem anxious to be solved.
In summary, existing coaxial cable obviously exists inconvenience and defective, so be necessary to be improved on reality is used.
The utility model content
At above-mentioned defective, the purpose of this utility model is to provide a kind of coaxial cable, to alleviate the weight of coaxial cable, guarantees that simultaneously the electricity function index of coaxial cable is constant.
To achieve these goals, the utility model provides a kind of coaxial cable, comprises inner wire, insulating barrier, outer conductor and restrictive coating from inside to outside successively, and described outer conductor comprises magnalium layer, copper layer and tin layer from inside to outside successively.
According to described coaxial cable, described magnalium layer and copper layer knitting forming, the immersion plating of described tin layer is in the outer surface of described magnalium layer and copper layer knitting forming body.
According to described coaxial cable, described copper layer is the tin-coated copper material.
According to described coaxial cable, described magnalium layer is the almag material.
According to described coaxial cable, described inner wire is the silver-coated copper wire material.
According to described coaxial cable, described insulating barrier is the polytetrafluoroethylene material.
According to described coaxial cable, described restrictive coating is the thermoplastic low-smoke halide-free fireproof composite polyolefine material.
The utility model is set to comprise successively from inside to outside magnalium layer copper layer and tin layer by the outer conductor of coaxial cable, not only make described coaxial cable have the electric index the same with traditional high-frequency transmission cable, and compare with existing cable, alleviate the weight of product, reduced the cost of product.
Description of drawings
Fig. 1 is the structural representation of the coaxial cable that provides of the utility model;
Fig. 2 is the structural representation of the outer conductor of the coaxial cable that provides of the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Referring to Fig. 1 and Fig. 2, the utility model provides a kind of coaxial cable 100, coaxial cable 100 comprises inner wire 10, insulating barrier 20, outer conductor 30 and restrictive coating 40 from inside to outside successively, and outer conductor 30 comprises magnalium layer 31, copper layer 32 and tin layer 33 from inside to outside successively.Magnalium layer 31 and copper layer 32 knitting forming, 33 immersion plating of tin layer are in the outer surface of magnalium layer 31 and copper layer 32 knitting forming body.
In the utility model, inner wire 10, insulating barrier 20, outer conductor 30 and restrictive coating 40 are coaxial, and outer conductor 30 is made of the tin-coated copper plated aluminium magnesium alloy wire, and it comprises magnalium layer 31, copper layer 32 and tin layer 33 from inside to outside successively.Outer conductor 30 has good electrical conductivity, shielding and the tensile strength of copper cash concurrently; Than the light specific gravity of copper, characteristics such as price is low.This coaxial cable 100 belongs to the teflon insulation semi-flexible coaxial cable 100 that is suitable for transmitting high-frequency signal in all kinds of radio, microwave communication, the microwave measuring equipment mobile communication equipment.
In an embodiment of the present utility model, described copper layer 32 is the tin-coated copper material.Described magnalium layer 31 is the almag material.Adopt these two kinds of materials making copper layers 32 and magnalium layer 31 can make outer conductor 30, make outer conductor 30 in the braiding process, be difficult for broken string, improved braiding speed and weaving quality greatly, enhance productivity owing to its tensile strength height.
In addition, the coaxial cable 100 that the utility model provides belongs to tetrafluoroethene insulation semi-flexible coaxial cable 100, its transmission 100MHz-3000MHz high-frequency signal, and current concentration is at the outer surface of inner wire 10, and the inner surface of outer conductor 30 transmits.This shows that outer conductor 30 internal material character do not influence electrical property.Compare with existing tetrafluoroethene insulation semi-flexible coaxial cable 100, the structure of same specification tin-coated copper plated aluminium magnesium alloy wire is as the outer conductor 30 of tetrafluoroethene insulation semi-flexible coaxial cable 100, with the 71000 yuan of calculating per ton of futures copper valency, every kilometer can alleviate 9.18 kilograms of product weights, reduce cost 855.27 yuan through actual verification, test result shows that electricity function index is the same with existing tetrafluoroethene insulation semi-flexible coaxial cable.
In an embodiment of the present utility model, inner wire 10 is the silver-coated copper wire material; Insulating barrier 20 is the polytetrafluoroethylene material; Restrictive coating 40 is the thermoplastic low-smoke halide-free fireproof composite polyolefine material.In this embodiment, inner wire 10 is a silver-coated copper wire; Insulating barrier 20 is for pushing teflon insulation; Outer conductor 30 is by tin-coated copper plated aluminium magnesium alloy wire braiding rear surface wicking; Restrictive coating 40 is a thermoplastic low-smoke halide-free fireproof composite polyolefine.Coaxial cable 100 adopts tin-coated copper plated aluminium magnesium alloy wire outer conductor 30 structures to replace the outer conductor structure of tinned wird, has optimized coaxial cable 100 structures, has enhanced productivity, reduces production costs.And the electricity function index that has guaranteed coaxial cable 100 is the same with former cable.
In sum, the utility model is set to comprise successively from inside to outside magnalium layer copper layer and tin layer by the outer conductor of coaxial cable, not only make described coaxial cable have the electric index the same with traditional high-frequency transmission cable, and compare with existing cable, alleviate the weight of product, reduced the cost of product.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
