Abstract
The invention relates to an anti-interference communication cable which comprises an accommodating cavity, wherein a cable core body is arranged in the accommodating cavity. The anti-interference communication cable is characterized in that the cable core body comprises a communication conductor, a main insulation layer is arranged on the periphery of the communication conductor, a protective layer is arranged outside the main insulation layer, and a shielding component is arranged outside the protective layer. Therefore, electro-magnetic induction, imperfect earth and power line conducted interference can be resisted, inductance is reduced, and induced electromotive force is prevented from getting excessive. According to the anti-interference communication cable, electromagnetic radiation, electrostatic coupling and electro-magnetic induction generated among cable cores and electromagnetic interference from the outside are effectively controlled; when interference occurs to a line, the load generated is led out through an earth wire core material and the cable is not affected at all. Furthermore, a magnetic steel belt shielding layer has a good magnetic conducting function, improves the reliability of equipment and the accuracy of data transmission, and facilitates the communication of network data.
Description
Technical field
The present invention relates to a kind of cable, relate in particular to a kind of anti-interference formula communication cable.
Background technology
For at a high speed accurate network data transmission, it is to electromagnetic interference sensitivity very, the online wicking surface of existing communication cable and cable core surface all do not have shielding construction, in use, can not shield the interference signal and the extraneous electromagnetic interference that produce between the communication cable.And the communication cable of design all was that ground connection core sectional area is equal to or less than master core in the past, thereby ground lead resistance is bigger, and the cable interference free performance is bad, thereby causes precise information distortion to occur.
Summary of the invention
Purpose of the present invention is exactly in order to solve the above-mentioned problems in the prior art, and a kind of anti-interference formula communication cable is provided.
Purpose of the present invention is achieved through the following technical solutions:
Anti-interference formula communication cable; include container cavity; be distributed with the cable core body in the described container cavity; wherein: described cable core body includes the communication conductor; described communication conductor outer periphery is equipped with main insulating layer; described main insulating layer is distributed with protective layer outward, and described protective layer is distributed with shield assembly outward.
Above-mentioned anti-interference formula communication cable, wherein: described shield assembly comprises bed course, and described bed course is distributed with magnetic conduction steel band screen outward, and described magnetic conduction steel band screen is outside equipped with sheath.
Further, above-mentioned anti-interference formula communication cable, wherein: be distributed with the ground wire core in the described container cavity.
Again further, above-mentioned anti-interference formula communication cable, wherein: described ground wire core includes the ground wire core conductor, and described ground wire core conductor is outside equipped with secondary insulating barrier.
The advantage of technical solution of the present invention is mainly reflected in: can anti-electromagnetic induction, imperfect earth and power line conducted interference, reduce inductance, and prevent that induced electromotive force is excessive.This structure has effectively been controlled electromagnetic radiation, static coupling and electromagnetic induction and the extraneous electromagnetic interference that produces between the core, when disturbing appears in circuit, the load that produces is derived by the ground wire core, cable itself is not produced any influence, in addition, by magnetic conduction steel band screen, played good magnetic conduction effect, improve the reliability of equipment and the accuracy of transfer of data, be conducive to the communication of network data.
Description of drawings
Purpose of the present invention, advantage and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using technical solution of the present invention, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of protection of present invention.In the middle of these accompanying drawings,
Fig. 1 is the cross-sectional configuration schematic diagram of anti-interference formula communication cable.
1 container cavity, 2 communication conductors
3 main insulating layers, 4 protective layers
5 bed courses, 6 magnetic conduction steel band screens

9 secondary insulating barriers
Embodiment
Anti-interference formula communication cable as shown in Figure 1 includes container cavity 1, is distributed with the cable core body in the container cavity 1, and its unusual part is: cable core body of the present invention includes communication conductor 1.Specifically, be equipped with main insulating layer 3 in communication conductor 1 outer periphery, these main insulating layer 3 outer protective layers 4 that are distributed with.Simultaneously, outside protective layer 4, be distributed with shield assembly.
With regard to the present invention's one preferred implementation, for effectively isolated extraneous signal disturbs, improve the transfer of data accuracy of Content of communciation, the shield assembly of employing comprises bed course 5, is distributed with magnetic conduction steel band screen 6 outside bed course 5.Simultaneously, consider the bulk strength that can promote cable, prevent from being subjected to external force unnecessary deformation to occur, magnetic conduction steel band screen 6 is outside equipped with sheath 7.
Further, consider to prevent the signal of telecommunication really, carry out effective ground connection, in container cavity 1, be distributed with the ground wire core.And in order effectively to reduce the electromagnetic effect from the ground wire core, the ground wire core of employing includes ground wire core conductor 8, is outside equipped with secondary insulating barrier 9 at ground wire core conductor 8.
By above-mentioned character express as can be seen, adopt the present invention after, can anti-electromagnetic induction, imperfect earth and power line conducted interference, reduce inductance, prevent that induced electromotive force is excessive.This structure has effectively been controlled electromagnetic radiation, static coupling and electromagnetic induction and the extraneous electromagnetic interference that produces between the core, when disturbing appears in circuit, the load that produces is derived by the ground wire core, cable itself is not produced any influence, in addition, by magnetic conduction steel band screen, played good magnetic conduction effect, improve the reliability of equipment and the accuracy of transfer of data, be conducive to the communication of network data.
