Abstract
The invention discloses a compound high fidelity coaxial cable. The compound high fidelity coaxial cable comprises an inner conductor (1), an insulation layer (2), a weaving layer (4) and a sheath layer (6) from internal to external; the internal surface of the weaving layer (4) is provided with a copper plastic composite belt shielding layer (3); and the external surface of the weaving layer (4) is provided with an aluminum plastic composite belt protective layer (5). According to the compound high fidelity coaxial cable, anti-interference performance of the cable is improved due to the fact that the weaving layer (4) which is arranged on the external surface and the copper plastic composite belt which is good in shielding performance and strong in the anti-resistance performance formed into a set of composite shielding layers; the shielding performance is improved and the composite shielding layers which are arranged in the internal are protected due to the fact that the aluminum plastic composite belt protective layer (5) is arranged on the external of the weaving layer (4), and accordingly moisture absorption and oxidization possibilities of the composite shielding layers are reduced and long-term and high-efficiency shielding effect is guaranteed.
Description
Technical field
The present invention relates to a kind of coaxial cable, be specifically related to a kind of compound high-fidelity coaxial cable.
Background technology
The structure of existing coaxial cable only comprises inner wire, insulating barrier, braid and four parts of restrictive coating.
In signals transmission, anti-external disturbance performance and the signal fidelity of the coaxial cable of this structure are relatively poor, cause distorted signals easily, so the signal transmission is very unstable, and image transmitted is also very unintelligible.And the existing coaxial cable humidity resistance is not fine, and is oxidized easily.
Summary of the invention
At the deficiency that prior art exists, the object of the invention provides a kind of compound high-fidelity coaxial cable, and interference free performance is strong and humidity resistance is better, it is oxidized to be difficult for.
To achieve these goals, the present invention realizes by the following technical solutions:
The present invention comprises inner wire, insulating barrier, braid and restrictive coating from inside to outside successively, and the inner surface of braid is provided with the compound copper-plastics band screen, and the outer surface of braid is provided with the aluminium-plastic tape overcoat.
What above-mentioned braid specifically adopted is the copper wire braid.
Beneficial effect of the present invention is as follows:
Because compound copper-plastics band has good shielding, interference free performance is very strong, add the braid of outside, formed a cover composite shielding layer, thereby, strengthened the interference free performance of cable of the present invention greatly, the signal transmission is more stable, and image transmitted is also more clear; Braid has increased the aluminium-plastic tape overcoat outward; the shielding properties of cable can not only be further improved, inner composite shielding layer can also be protected, thereby; greatly reduce the possibility of composite shielding layer moisture absorption of the present invention, oxidation, guaranteed cable for a long time, shield effectiveness efficiently.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
Referring to Fig. 1, the present invention comprises inner wire 1, insulating barrier 2, braid 4 and restrictive coating 6 from inside to outside successively.
Wherein, the inner surface of braid 4 is provided with compound copper-plastics band screen 3.
The composite shielding layer that compound copper-plastics band screen 3 of the present invention and braid 4 are formed is copper material, except can be used as outer conductor, also can play excellent shielding effect, further improves the interference free performance of whole cable.
Wherein, the outer surface of braid 4 is provided with aluminium-plastic tape overcoat 5.
Aluminium-plastic tape overcoat 5 of the present invention is when improving shield effectiveness, and effectively protection compound copper-plastics band screen 3 and braid 4 are avoided the infiltration of wet gas in the long-term use, reduces the probability of composite shielding layer oxidation.
In addition, aluminium-plastic tape overcoat 5 can also play the certain protection effect to cable inside except playing the effect of making up shielding, effectively prolong the useful life of cable.
In the present embodiment, what braid 4 specifically adopted is the copper wire braid.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
