Abstract

The utility model discloses an anti -interference composite cable, including a cable core, the cable core be equipped with optical fiber unit and around forming in optical fiber unit insulation core transposition all around by the center, being equipped with the weaving layer outside the cable core, being provided with copper at the internal surface of weaving layer and moulding and compoundly take the shielding layer, the surface of weaving layer is provided with the composite aluminium -plastic tape inoxidizing coating, and an outer sheath is extruded outside the outermost layer of the cable. The utility model discloses the anti -interference ability of cable is strong, and signal transmission is more stable, the image of transmission is also more clear, has reduced the possibility of composite shielding layer moisture absorption, oxidation, has guaranteed that the cable is long -term, efficient shielding effect, and when the cable was crooked, the filler was oppressed by insulation core, made the outer fringe of filler warp to make the cable have crooked durability and reelability, the cable can use under alternating bending's environment, has improved the environmental suitability of cable.

Description

A kind of anti-interference composite cable

Technical field

The utility model relates to field of cable technology, is specially a kind of anti-interference composite cable.

Background technology

The existing construction of cable comprises many conductors, be coated on the insulating barrier outside each conductor, braid and restrictive coating four parts, wherein, conductor and insulating barrier form insulated wire cores, braid is wrapped in the outside of many insulated wire cores, restrictive coating is coated on the outer surface of braid, in signals transmission, anti-external disturbance performance and the envelope eapsulotomy of the cable of this structure are poor, easily cause distorted signals, therefore Signal transmissions is very unstable, the image of transmission is also very unintelligible, and existing cable humidity resistance is not fine, easily oxidized, bear the environment of alternating bending at automobile etc. under, the cable used not only requires high bending durability, and from the view point of easily carrying out distribution, also high pliability is required, existing cable still can not realize high bending durability and high pliability simultaneously, thus reduce the environmental suitability of cable, in addition, be all adopt independent structure in existing technology, make the performance of cable also single.

Utility model content

The purpose of this utility model is to provide one to have strong anti-interference performance, and Signal transmissions is more stable, the anti-interference composite cable of the image of transmission also more clear, high reliability data transmission performance.

For achieving the above object, the anti-interference composite cable of one described in the utility model, comprises cable core, and described cable core Shi You center is provided with fiber unit and is centered around that the insulated wire cores of fiber unit surrounding is stranded to be formed; Outside cable core, be provided with braid, the inner surface of braid is provided with the compound copper-plastics band screen that thickness is 0.15mm-0.5mm, the outer surface of braid is provided with the aluminium-plastic tape overcoat that thickness is 0.15mm-0.5mm; The outermost layer of cable is extruded with oversheath.

Preferably, described insulated wire cores is made up of conductor and the insulating barrier be extruded in outside conductor.

Preferably, described braid is the overcoat be made by copper material.

Compared with prior art, the beneficial effects of the utility model are: this Anti-interference cable, the strong anti-interference performance of cable, Signal transmissions is more stable, the image of transmission is also more clear, reduce the possibility of composite shielding layer moisture absorption, oxidation, ensure that long-term, the efficient shield effectiveness of cable, during cable bend, filler is oppressed by insulated wire cores, makes the outer margin deformation of filler, thus makes cable have bending durability and reelability, cable can use under the environment of alternating bending, improves the environmental suitability of cable; Power cable and communications optical cable are fused in a cable, while electric energy is provided, the same net Signal transmissions of telecommunications network, broadcasting and television network, the Internet can be realized; Achieve technically only need once construct, problem that passage, a disposable solution cable are registered one's residence, the repeatedly construction of many circuits such as electric wire, netting twine, telephone wire, cable television line in the past can be replaced, greatly save cable resource and conduit resource.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

Embodiment

As shown in Figure 1, the anti-interference composite cable of one described in the utility model, comprises cable core, and described cable core Shi You center is provided with fiber unit 2 and is centered around that the insulated wire cores of fiber unit 2 surrounding is stranded to be formed; Outside cable core, be provided with braid 6, the inner surface of braid 6 is provided with the compound copper-plastics band screen 7 that thickness is 0.15mm-0.5mm, the outer surface of braid 7 is provided with the aluminium-plastic tape overcoat 5 that thickness is 0.15mm-0.5mm; The outermost layer of cable is extruded with oversheath 4; Described insulated wire cores is made up of conductor 1 and the insulating barrier 3 be extruded in outside conductor 1; Described braid 6 is the overcoats be made by copper material.

Operation principle of the present utility model: adopt compound copper-plastics band screen 7, there is good shielding, interference free performance is very strong, add the braid 6 of outside, constitute a set of composite shielding layer, greatly strengthen the interference free performance of cable, Signal transmissions is more stable, the image of transmission is also more clear, aluminium-plastic tape overcoat 5 is added outside braid 6, the shielding properties of cable can not only be improved further, inner composite shielding layer can also be protected, greatly reduce composite shielding layer moisture absorption, the possibility of oxidation, ensure that cable is long-term, efficient shield effectiveness, many insulated wire cores are arranged on fiber unit 2 around, optical fiber is fused in a cable, while electric energy is provided, telecommunications network can be realized, broadcasting and television network, the same net Signal transmissions of the Internet, achieve technically only need once construct, problem that passage, a disposable solution cable are registered one's residence, the repeatedly construction of many circuits such as electric wire, netting twine, telephone wire, cable television line in the past can be replaced, greatly save cable resource and conduit resource.Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
