Abstract
The utility model relates to a coaxial cable, comprising an inner conductor, an insulating layer, an outer conductor and a sheath which are sequentially arranged from inside to outside. The inner conductor takes an aluminium coil as the base body and the outer layer of the inner conductor is wrapped by pure copper and is drawn and then annealed. Due to skin effect of the signal transmission, if the coaxial cable adopts an inner conductor made of pure copper, a large amount of material can be wasted. The inner conductor takes the aluminium coil as the base body and the outer layer of the inner conductor is coated by pure copper, so the cable can satisfy the requirement for high-frequency signal transmission, and meanwhile the cost and the weight of the cable are reduced. The outer conductor is a structure combined from a mesh grid and a longitudinal wrapping aluminium-plastic composite belt. By replacing the conventional 16-ingot weaving mode with the 24-ingot weaving mode, the utility model can weave a reticular woven structure with long pitch and thick twines, reduces the shielding resistance and improves the shielding efficiency of the cable while maintaining the weaving density and not increasing the cost.
Description
Technical field
The utility model relates to a kind of coaxial cable, particularly a kind of novel coaxial cable of suitable 3G network transmission.
Background technology
Coaxial cable is mainly used in propagate radio frequency signals, traditional coaxial cable adopts copper wire as inner wire, because the skin effect of signal transmission, adopt full copper inner wire, can bring raw-material significant wastage, the structure of the outer conductor of coaxial cable also has very big influence to the overall performance of cable simultaneously, the resistance of shielding attenuation and outer conductor particularly, rely on the simple way that changes lay of braiding of tradition, can not effectively improve shielding properties, reduce shielding attenuation and shielding resistance.
The utility model content
The purpose of this utility model provides a kind of coaxial cable, and it has improved shielding properties, has reduced production cost.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs:
A kind of coaxial cable comprises the inner wire, insulating barrier, outer conductor, the sheath that set gradually from inside to outside, and described inner wire is a matrix with the aluminium core, the outer fine copper that coats.Because the skin effect of signal transmission adopts full copper inner wire, can bring raw-material significant wastage, it is matrix that inner wire adopts with the aluminium core, and the outer fine copper that coats when satisfying the cable high-frequency signal transmission, has reduced cost, has alleviated weight.
As preferably, described inner wire is a kind of soft attitude copper-clad aluminum conductor.Annealed after its drawing, pliability is better.
As preferably, described outer conductor is the combining structure of mesh grid and aluminum plastic composite belt longitudinal bag.As of the present utility model further preferred, described mesh grid is the netted braiding structure of meropodium distance, coarse net silk.By changing 24 ingot braiding machines into by traditional 16 ingots braiding, knit out the netted braiding structure of meropodium distance, coarse net silk, under the prerequisite that guarantees that count is constant, do not increase cost, reduced the shielding resistance of cable, improved screening effectiveness.
In sum, the utlity model has following beneficial effect:
1, inner wire of the present utility model is soft attitude copper cover aluminum, with traditional comparing as inner wire with copper wire, provides cost savings, and has alleviated the overall weight of coaxial cable, and has pliability preferably.
2, outer conductor of the present utility model is the combining structure of mesh grid and aluminum plastic composite belt longitudinal bag, by making the braiding of 24 ingots into by traditional 16 ingots braiding, knit out the netted braiding structure of meropodium distance, coarse net silk, under the prerequisite that guarantees that count is constant, do not increase cost, reduce the shielding resistance of cable, improved screening effectiveness.
Description of drawings
Fig. 1 is a perspective view of the present utility model.
In the accompanying drawing: 1. inner wire, 2. insulating barrier, 3. outer conductor, 4. sheath, 1a. aluminium core, 1b. copper layer.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
This specific embodiment only is to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification, but as long as all are subjected to the protection of Patent Law in claim scope of the present utility model.
Shown in figure one: a kind of coaxial cable, comprise the inner wire 1, insulating barrier 2, outer conductor 3, the sheath 4 that set gradually from inside to outside, described inner wire is to be matrix with aluminium core 1a, the outer soft attitude copper-clad aluminum conductor that coats fine copper 1b, with respect to traditional be the structure of inner wire with the copper wire, provide cost savings, alleviated the overall weight of coaxial cable, and have pliability preferably.Described outer conductor 3 closes for mesh grid and aluminum plastic composite belt longitudinal package, by making the braiding of 24 ingots into by traditional 16 ingots braiding, knit out the netted braiding structure of meropodium distance, coarse net silk, under the prerequisite that guarantees that count is constant, do not increase cost, reduce the shielding resistance of cable, improved screening effectiveness.
