Description
Technical field
The utility model discloses a kind of shielded type cable, belong to cable technology field, more specifically a kind of shielded type cable of anti-electromagnetic interference.
Background technology
At present, in China, infrastructure construction constantly drops into, and the demand of power cable increases day by day.And in Nuclear measurement system, because the particle flux signal that radiation produces is very faint, in order to detect these faint signals, require the stube cable of instrument cubicle in Nuclear measurement system to have excellent anti-external interference ability, make shield effectiveness approach 100%.In addition, the cable connection in portion, the device of nuclear hardening key, requires to have super screen effect under the impact of its strong electromagnetic pulse producing in the time of the other side's nuclear blast, and interference is reduced to minimum, and anti-nuclear strike system can normally be worked.The shielding of its outer conductor of existing high shielded type cable has one to become screen to two-layer proof copper-wire braided conventionally, or formed by overall copper pipe, when actual use, can not meet the requirement of Nuclear measurement system, nuclear hardening system completely, and most cables is to only have total shielding, there is no separated-shielding, the ability of anti-electromagnetic interference between line pair is reduced.
The purpose of this utility model is, provides a kind of simple, the shielded type cable of the anti-electromagnetic interference that cost is low, have better shield effectiveness, thus meet the stube cable still with desirable shield effectiveness under strong magnetic, make shield effectiveness approach 100%.
Summary of the invention
For the problems referred to above, the utility model provides a kind of shielded type cable of anti-electromagnetic interference, it is characterized in that, the shielded type cable of described anti-electromagnetic interference therefrom mind-set is followed successively by heart yearn, insulating coating, braid and protective sleeve outward; Wherein said insulating coating is coated on the circumferential outer surface of described heart yearn; Described braid fits tightly the outer surface at described insulating coating; Described protective sleeve adopts individual layer black polyethylene protective sleeve, and described protective sleeve is closely coated on the outer surface of described insulating coating, in order to protect cable; Described heart yearn comprises heart yearn round conductor, insulating barrier and the coat of metal; Wherein, described insulating barrier is coated on the circumference of described heart yearn round conductor, the described coat of metal is plated on metal material by surface-treated mode the circumferential surface of described insulating barrier, and the coat of metal covers on the surface of described insulating barrier completely, thereby heart yearn round conductor is shielded completely; Described heart yearn is 2-3 root.
In order to make in stable condition between heart yearn, there will not be the situation of slippage between each heart yearn, between described heart yearn, be configured in described insulating coating in hinged mode.
Certainly, in order to save hinged operation, making to manufacture simply, and save the consumption of heart yearn, there is no the occasion of particular/special requirement, is to save manufacturing cost, between described heart yearn, is configured in described insulating coating in parallel mode arranged side by side.
In order to make heart yearn round conductor not be subject to extraneous strong electromagnetic completely, adopt certain reliable surface treatment mode that metal material is plated on the circumferential surface of described insulating barrier, and the surface treatment mode of comparative optimization is plating, chemical plating or vacuum evaporation.
In order to obtain reasonable shield effectiveness and to consider in conjunction with manufacturing cost, the thickness of the described coat of metal is 0.01-0.05mm.
In addition, can also adopt the mode of plasma plating that metal material is plated on the circumferential surface of described insulating barrier.
In order further to improve the shielding action of cable, make cable still there is 100% shielding rate under the environment of strong magnetic, between described insulating coating and braid, be also provided with foil shielding layer.
The beneficial effects of the utility model: the utility model not only adopts bulk shielding, and adopted separated-shielding, the ability of anti-electromagnetic interference between heart yearn and heart yearn is strengthened, and can effectively shield extraneous electromagnetic interference.The utility model, compared with traditional shielded type cable, by adopting surface treatment mode, is each heart yearn plating layer of metal coating, can greatly strengthen the shielding properties of cable.And the utility model manufacture is simple, easy to use, with low cost, practical, there is significant improvement, successful at aspects such as structure, technique, means.
