The demand of cable will also increase rapidly, and there are also huge development potentialities for the following wire and cable industry.
In the related art, the structure of coaxial cable is led including including inner conductor and from inside to outside sequentially coaxially coated
Insulating layer, shielded layer and protective layer on body, aluminium foil layer of the shielded layer usually by being coated on insulating layer external peripheral surface
And it is coated on the wire sheathing composition outside aluminium foil layer.Coaxial cable manufacturing enterprise at present is compiled with high speed more and more
Loom carrys out braided metal braiding layer；But phenomena such as aluminium foil often will appear flange in the weaving process, gauffer, affects cable biography
Defeated performance.Moreover, often only with one layer of aluminium foil layer in this cable, once there is aluminium foil layer breakage, shield effectiveness is beaten greatly
Discount.
[utility model content]
The utility model discloses a kind of high-performance coaxial cable, the cable solved in the related technology is easy to appear aluminium foil
Layer flange and fold, the technical issues of one layer of aluminium foil layer being only set, influences shield effectiveness after damaged in cable.
To achieve the above object, the technical solution of the utility model are as follows:
A kind of high-performance coaxial cable, including inner conductor, insulating layer, outer conductor, electro-insulating rubber layer, shielded layer and protection
Layer, the inner conductor are flush-mounted in the outer conductor by the insulating layer, and the inner conductor and the outer conductor are in same
The heart justifies position, and the electro-insulating rubber layer is wrapped up outside the outer conductor, and the shielded layer wraps up outside the electro-insulating rubber layer, institute
It states protective layer to wrap up outside the shielded layer, the shielded layer includes coating outside the electro-insulating rubber layer in transport screw shape
First aluminium foil layer coats the second aluminium foil layer outside first aluminium foil layer in reverse acting spiral shape, is located in first aluminium foil
The wire sheathing outside two-sided foam rubber and cladding second aluminium foil layer between layer and second aluminium foil layer.
Preferably, the wire sheathing is formed by complex root metal wire knitted.
Preferably, the wire is any one in iron wire, spun gold or filamentary silver.
The beneficial effects of the utility model are as follows:
1, the shielded layer in the utility model includes aluminium foil layer and wire sheathing, can be obviously improved shield effectiveness；
2, it is arranged using the first aluminium foil layer in right-handed screw shape, the second aluminium foil layer is arranged in backpitch shape, when one layer of aluminium of appearance
When layers of foil breakage, on the shield effectiveness of shielded layer, there are few influences；
3, by the way that two-sided foam rubber is arranged between the first aluminium foil layer and the second aluminium foil layer, also it is not easy after aluminium foil layer is damaged
There is flange, so that damaged area will not be expanded.
[Detailed description of the invention]
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings, in which:
Fig. 1 is a kind of structural schematic diagram of high-performance coaxial cable of the utility model.
[specific embodiment]
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
All other embodiment obtained, fall within the protection scope of the utility model.
Refering to Figure 1, the utility model provides a kind of high-performance coaxial cable 100, including inner conductor 1, insulating layer
2, outer conductor 3, electro-insulating rubber layer 4, shielded layer 5 and protective layer 6, the inner conductor 1 is by the insulating layer 2 flush-mounted in described
In outer conductor 3, and the inner conductor 1 and the outer conductor 3 are in concentric circles position, and the electro-insulating rubber layer 4 is wrapped up described outer
Outside conductor 3, the shielded layer 5 is wrapped up outside the electro-insulating rubber layer 4, and the protective layer 6 wraps up outside the shielded layer 5.
The electro-insulating rubber layer 4 is set between the outer conductor 3 and the shielded layer 5, can not only play electrical isolation
Function, and using rubber itself elasticity, 5 damaged probability of shielded layer can be reduced.
The shielded layer 5 includes the first aluminium foil layer 51 electro-insulating rubber layer 4 outside being coated in transport screw shape, in instead
The second aluminium foil layer 52 outside first aluminium foil layer 51 is coated to helical form, is located in first aluminium foil layer 51 and described
The wire sheathing 54 outside two-sided foam rubber 53 and cladding second aluminium foil layer 52 between two aluminium foil layers 52.By institute
It states the first aluminium foil layer 51 and second aluminium foil layer 52 is arranged in the shape of a spiral, therefore, the edge of aluminium foil layer is not easy to turn down, can
To effectively prevent phenomena such as flange and fold occurs in aluminium foil layer when weaving the wire sheathing 54.
The utility model is arranged using Double-layer aluminum layers of foil, and any one layer of appearance is damaged, to the shield effectiveness of the shielded layer 5
There are few influences.Again by the way that the two-sided foam rubber 53 is arranged between first aluminium foil layer 51 and second aluminium foil layer 52,
It only will continue to be bonded in the two-sided foam rubber 53 after aluminium foil layer is damaged, it is not easy to flange occur, so that breakage will not be expanded
Area.
