Abstract
The invention discloses an anti-electromagnetic interference control cable relating to the technical field of control signal transmission. The anti-electromagnetic interference control cable comprises a plurality of strands of thin bare copper wire conductors twisted into a beam, a core wire insulation layer, an inner jacket, a braided shield layer and an outer jacket, wherein the copper wire conductors wrapped with the core wire insulation layer are bundled by the inner jacket, the braided shield layer is wrapped on the outer layer of the inner jacket, and the outer jacket is wrapped on the outer layer of the braided shield layer. The anti-electromagnetic interference control cable is reasonable in design and simple in structure, is greatly improved in shielding effect because the shield is braided from tinned copper wires, can effectively ensure the quality of transmitted signals of the cable in an environment of serious interference of an electromagnetic field, ensures reliable and stable operation of a connecting device, and can be widely applicable to being installed in occasions possibly causing signal transmission distortion due to electrical interference.
Description
Technical field
The present invention relates to the control signal transmission technique field, be specifically related to a kind of control cable of anti-electromagnetic interference.
Background technology
Along with progress of science and technology and development and national economy, various advanced persons' instrument is constantly released and is used with control, and quantity is also in continuous increase, and monitoring circuit also constantly increases with the protection loop.Simultaneously, the environment of cable installation also becomes increasingly complex, environmental interference and and cable between the phase mutual interference also more and more serious.Traditional control cable, its shielding construction is simple, shield effectiveness is poor, antijamming capability a little less than, in the electromagnetic interference serious environmental, influence transmission quality, cause instrument and circuit hidden danger safe in utilization to occur.
Summary of the invention
The control cable that the purpose of this invention is to provide a kind of anti-electromagnetic interference; It adopts tinned copper wire or braided steel wire to form shielding; Its shield effectiveness improves greatly, can effectively guarantee cable signal transmission quality in interference of electromagnetic field serious environmental, guarantees the reliable and stable operation of its connection device.
In order to solve the existing problem of background technology; The present invention adopts following technical scheme: a kind of control cable of anti-electromagnetic interference; It comprises that multiply carefully is twisted into the thin bare copper wire conductor of bundle, core insulation layer, inner sheath, woven shield and oversheath; Said inner sheath is enclosed with the copper wire conductor of core insulation layer, and the skin of said inner sheath is enclosed with woven shield, and the skin of said woven shield is enclosed with oversheath.
As improvement, said woven shield is tinned copper wire or oxidation resistant steel wire interlacing layer.
As improvement, said core insulation layer is a PVC compound core insulation layer.
As improvement, said inner sheath is a PVC compound inner sheath.
As improvement, said oversheath is the transparent oversheath of PVC compound.
As improvement, said copper wire conductor cores number is for more than at least three.
The present invention is reasonable in design, and is simple in structure, adopts tinned copper wire or braided steel wire to form shielding, and its shield effectiveness improves greatly, can effectively guarantee cable signal transmission quality in interference of electromagnetic field serious environmental, guarantees the reliable and stable operation of its connection device; Can extensively be suitable for and be installed in because of receiving electrical Interference possibly cause the occasion of signal transmission distortion.
Description of drawings
Fig. 1 is a structural representation of the present invention.

With reference to Fig. 1; This embodiment adopts following technical scheme: a kind of control cable of anti-electromagnetic interference; It comprises that multiply carefully is twisted into the thin bare copper wire conductor of bundle 1, core insulation layer 2, inner sheath 3, woven shield 4 and oversheath 5; Said inner sheath 3 is enclosed with the copper wire conductor 1 of core insulation layer 2, and the skin of said inner sheath 3 is enclosed with woven shield 4, and the skin of said woven shield 4 is enclosed with oversheath 5.
Said woven shield 4 is tinned copper wire or oxidation resistant steel wire interlacing layer, has improved antijamming capability and oxidation resistance greatly, has multiple protective, can under bad working environment, use.
Said core insulation layer 2 is a PVC compound core insulation layer.
Said inner sheath 3 is a PVC compound inner sheath.
Said oversheath 5 is the transparent oversheath of PVC compound, makes woven shield avoid dirty and mechanical damage, gives pleasing outward appearance.
Said copper wire conductor 1 core number is for more than at least three.
This embodiment both can be transmitted little electric current, also can transmit big electric current, and received outside interference when farthest having reduced the signal transmission.
This embodiment is reasonable in design; Simple in structure, adopt tinned copper wire or braided steel wire to form shielding, its shield effectiveness improves greatly; Can effectively guarantee cable signal transmission quality in interference of electromagnetic field serious environmental, guarantee the reliable and stable operation of its connection device; Can extensively be suitable for and be installed in because of receiving electrical Interference possibly cause the occasion of signal transmission distortion.
