Abstract
The utility model discloses a control cable having the anti-electromagnetic interference function, and relates to the technical field of control signal transmission. The control cable comprises a plurality of stranded and bundled thin bare copper wire conductors, core insulating layers, an inner sheath, a braided shielding layer and an outer sheath. The copper wire conductors provided with the core insulating layers are coated with the inner sheath, the outer layer of the inner sheath is coated with the braided shielding layer, and the outer layer of the braided shielding layer is coated with the outer sheath. According to the utility model, advantages of reasonable design and simple structure are realized, the shielding layer is formed by braiding tinned copper wires and steel wires together, so the shielding effect is greatly improved, the signal transmission quality of the cable in environments in which serious electromagnetic field interference exists can be effectively ensured, the reliable and stable operation of the connection equipment of the cable is ensured, and the cabel can be widely used and installed in occasions in which the signal transmission distortion may be caused by electrical interference.
Description
Technical field
The utility model relates to the control signal transmission technique field, is specifically related to a kind of control cables of anti-electromagnetic interference.
Background technology
Along with the progress of science and technology and the development of national economy, various advanced persons' instrument and control are constantly released and are used, and quantity is also in continuous increase, and monitoring circuit and protection loop also constantly increase.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 cables, its shielding construction is simple, shield effectiveness is poor, antijamming capability a little less than, in the serious environment of electromagnetic interference, affect transmission quality, cause instrument and circuit occur to use potential safety hazard.
Summary of the invention
The purpose of this utility model provides a kind of control cables of anti-electromagnetic interference, it adopts tinned copper wire or braided steel wire to form shielding, its shield effectiveness improves greatly, can effectively guarantee the quality of cable signal transmission in the serious environment of the interference of electromagnetic field, guarantee the reliable and stable operation of its connection device.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: a kind of control cables 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, described inner sheath is enclosed with the copper wire conductor of core insulation layer, the skin of described inner sheath is enclosed with woven shield, and the skin of described woven shield is enclosed with oversheath.
As improvement, described woven shield is tinned copper wire or oxidation resistant steel wire interlacing layer.
As improvement, described core insulation layer is PVC compound core insulation layer.
As improvement, described inner sheath is PVC compound inner sheath.
As improvement, described oversheath is the transparent oversheath of PVC compound.
As improvement, described copper wire conductor cores number is for more than at least three.
The utility model 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 the quality of cable signal transmission in the serious environment of the interference of electromagnetic field, guarantee the reliable and stable operation of its connection device; Can extensively be suitable for and be installed in because being subjected to electrical Interference may cause the occasion of signal transmission distortion.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, this embodiment is by the following technical solutions: a kind of control cables of anti-electromagnetic interference, it comprises that multiply carefully is twisted into the thin bare copper wire conductor 1 of bundle, core insulation layer 2, inner sheath 3, woven shield 4 and oversheath 5, described inner sheath 3 is enclosed with the copper wire conductor 1 of core insulation layer 2, the skin of described inner sheath 3 is enclosed with woven shield 4, and the skin of described woven shield 4 is enclosed with oversheath 5.
Described woven shield 4 is tinned copper wire or oxidation resistant steel wire interlacing layer, has greatly improved antijamming capability and oxidation resistance, has multiple protective, can use under abominable operational environment.
Described core insulation layer 2 is PVC compound core insulation layer.
Described inner sheath 3 is PVC compound inner sheath.
Described oversheath 5 is the transparent oversheath of PVC compound, so that woven shield is avoided dirty and mechanical damage, gives pleasing outward appearance.
Described 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 large electric current, and was subjected to 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 the quality of cable signal transmission in the serious environment of the interference of electromagnetic field, guarantee the reliable and stable operation of its connection device; Can extensively be suitable for and be installed in because being subjected to electrical Interference may cause the occasion of signal transmission distortion.
