Abstract
The utility model discloses a shielded type control cable having the anti-electromagnetic interference function, and relates to the technical field of control signal transmission. The shielded type control cable comprises a plurality of stranded and bundled thin bare copper wire conductors, core insulating layers, a plastic film thin layer, a braided shielding layer and an outer sheath. The copper wire conductors provided with the core insulating layers are bundled and coated with the plastic film thin layer, the outer layer of the plastic film thin layer 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 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, and the reliable and stable operation of the connection equipment of the cable is ensured.
Description
Technical field
The utility model relates to the control signal transmission technique field, is specifically related to a kind of anti-electromagnetic interference shielding control cables.
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 anti-electromagnetic interference shielding control cables, it adopts the tinned copper wire braiding 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, guarantees 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 anti-electromagnetic interference shielding control cables, it comprises that multiply carefully is twisted into the thin bare copper wire conductor of bundle, core insulation layer, plastic film layers, woven shield and oversheath, described plastic film layers is tied up the copper wire conductor that is enclosed with the core insulation layer, the skin of described plastic film layers is enclosed with woven shield, and the skin of described woven shield is enclosed with oversheath.
As improvement, described plastic film layers is the ambroin thin layer.
As improvement, described woven shield is tinned copper wire interlacing layer.
As improvement, described oversheath is PVC compound oversheath.
As improvement, described core insulation layer is PVC compound core insulation layer.
The utility model is reasonable in design, and is simple in structure, adopts the tinned copper wire braiding to form shielding, and its shield effectiveness improves greatly, and can effectively guarantee the quality of cable signal transmission in the serious environment of the interference of electromagnetic field, guarantees the reliable and stable operation of its connection device.
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 anti-electromagnetic interference shielding control cables, it comprises that multiply carefully is twisted into the thin bare copper wire conductor 1 of bundle, core insulation layer 2, plastic film layers 3, woven shield 4 and oversheath 5, described plastic film layers 3 is tied up the copper wire conductor 1 that is enclosed with core insulation layer 2, the skin that described plastic film is 3 layers is enclosed with woven shield 4, and the skin of described woven shield 4 is enclosed with oversheath 5.
Described plastic film layers 3 is the ambroin thin layer, does not use inner sheath, and the external diameter of its cable is significantly reduced, and saves installing space.
