Abstract
The invention discloses a cable. The cable comprises a plurality of insulated wire cores, a filler, a knitted layer and a protective sleeve layer, wherein the protective sleeve layer is arranged outside the knitted layer, the plurality of insulated wire cores are arranged around the filler, the knitted layer wraps the plurality of insulated wire cores, a copper and plastic composite shielding layer is arranged on the inner surface of the knitted layer, and a copper and plastic composite protective layer is arranged on the outer surface of the knitted layer. The cable is strong in anti-interference performance, more stable in signal transmission and clearer in transmitted image. The probability that the composite shielding layer absorbs moisture and is oxidized is reduced, and the long-term and efficient shielding effect of the cable is guaranteed. When the cable is bent, the filler is pressed by the insulated wire cores, the edge of the filler is made to deform, therefore, the cable is made to have bending durability and to be capable of being wound, the cable can be used in an environment where the cable is repeatedly bent, and the environmental suitability of the cable is improved.
Description
Technical field
The present invention relates to the cable that can under humidity and alternating bending condition, use.
Background technology
The existing construction of cable comprises many conductors, is coated on insulating barrier, braid and four parts of restrictive coating of each conductor outside, wherein, conductor and insulating barrier constitute insulated wire cores, and braid is wrapped in the outsides of thoroughly doing away with the edge core more, and restrictive coating is coated on the outer surface of braid.
In signals transmission, anti-external disturbance performance and the signal fidelity of the 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 existing cable humidity resistance is not fine, and is oxidized easily.In addition, bear under the environment of alternating bending at automobile etc., the cable of use is demanding crooked durability not only, and from carrying out the viewpoint of distribution easily, also demanding pliability, existing cable still can not be realized high crooked durability and high pliability simultaneously.Thereby reduced the environmental suitability of cable.
Summary of the invention
At the deficiency that prior art exists, the object of the invention provides the cable that can use under the alternating bending environment, 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 includes the restrictive coatings that thoroughly do away with edge cores, filler, braid and be arranged on the braid outside more, thoroughly do away with more the edge core be arranged on filler around; Braid is wrapped in the outsides of thoroughly doing away with the edge core more; 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.
Above-mentioned filler is made of resin.
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; Of the present invention thoroughly do away with the edge core be arranged on filler around, because filler has flexibility, be that filler has the character than insulated wire cores easy deformation, so when cable was crooked, filler was insulated the core compressing, make the outer margin deformation of filler, thereby make cable have crooked durability and reelability, cable can use under the environment of alternating bending, has improved the environmental suitability of cable.
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 includes six roots of sensation insulated wire cores, filler 7, be wrapped in braid 4, the restrictive coating 6 that is arranged on braid 4 outsides, compound copper-plastics band screen 3 and the aluminium-plastic tape overcoat 5 of six roots of sensation insulated wire cores outside.
Wherein, insulated wire cores is made of conductor 1 and the insulating barrier 2 that is coated on conductor 1 outside.
Six roots of sensation insulated wire cores be arranged on filler 7 around.
The centre of cable of the present invention is filler 7 but not insulated wire cores, when cable is crooked, the pressure that produces between insulated wire cores is absorbed by the distortion of filler 7, therefore, relaxed the pressure between the insulated wire cores, the broken string that has suppressed conductor 1, its result makes cable have high crooked durability.
Further, when cable was crooked, because filler 7 distortion, therefore, the flexural rigidity of cable was lower than general cable, and namely cable has high pliability, therefore, carries out distribution easily.
Thereby make cable have crooked durability and reelability, can under the environment of alternating bending, use.
In the present embodiment, filler 7 is made of resin.
Compound copper-plastics band screen 3 is located at the inner surface of braid 4.
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.
Aluminium-plastic tape overcoat 5 is located at the outer surface of braid 4.
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.
