Description
Technical field
The utility model discloses a kind of cable, more specifically a kind of cable with superhigh shielded performance.
Background technology
Electromagnetic shielding (Electro Magnetic Interference, EMI) cable is Signal transmissions wire rod comparatively conventional in electronic industry, and the electromagnetic shielded cable broader applications of micron order size are in IT product, medical instrument, Space Facilities.Traditional cable inside is provided with two conductors, inner wire in order to transmission of electric signals, outer conductor in order to shielding transmission the signal of telecommunication and be enclosed in inside, thus cable is had, and high-frequency loss is low, shielding and the characteristic such as antijamming capability is strong, service band is wide.
Generally, electromagnetic shielded cable structure is from the inside to the outside followed successively by the core forming inner wire, the insulating medium layer being coated on cable core outer surface, screen and oversheath.Wherein, cable core is used for transmission of electric signals, and material is based on copper or ormolu.Screen is generally layer of metal foil, in order to shield electromagnetic interference or the interference of useless external signal.But this shielded type cable can only be applicable to general shielding action, for the occasion that electromagnetic shielding requirements is higher, the shield effectiveness of this shielded type cable is limited, can not meet the requirement of superhigh shielded performance.
In sum, be necessary the cable that a kind of superelevation capability of electromagnetic shielding is provided, to meet the needs closed in electromagnetic shielding requirements high field.The utility model has supplied a kind of cable with superhigh shielded performance, and its structure is simple, have superhigh shielded performance.
Summary of the invention
For the problems referred to above; the utility model provides a kind of cable with superhigh shielded performance; it comprises cable core, the first insulating barrier, conductor shield, the second insulating barrier, metal mesh shield layer and protective sleeve; it is characterized in that; the first described insulating barrier is arranged between described cable core and described conductor shield; described conductor shield arranged outside has the second insulating barrier; described metal mesh shield layer is arranged between the second described insulating barrier and described protective sleeve; wherein, the outer surface of described conductor shield cross section is waveform curved surface.
The utility model arranges one deck conductor shield by increase, effectively can strengthen shielding action, and by arranging waveform curved surface on the outer surface of described conductor shield cross section, this waveform curved surface can significantly improve shielding properties, and this corrugated curved surface will improve about 30%-40% than the shielding properties of the screen of plane.
Further, as preferably, the first described insulating barrier and the second described insulating barrier adopt pvc material to make.
Further, in order to make cable have good buckling performance, hydraulic performance decline when preventing bending, the density that the first described insulating barrier is outside from axle center increases successively.
Further, the density that the second described insulating barrier is outside from axle center increases successively.
In order to improve shielding properties further, make the shielding properties of conductor shield reach best, the trough of the waveform curved surface of described conductor shield cross section and the height of crest are 1/10th of described conductor shield internal diameter.
In order to make conductor shield have preferably shielding properties, and reduce its manufacturing cost, described conductor shield adopts soft alloy to make.
In addition, further, as preferably, described conductor shield adopts copper or tin to make.
As preferably, described cable core is 3-4 root.
The beneficial effects of the utility model: the utility model has the following advantages:
1, the utility model arranges one deck conductor shield by increase, effectively can strengthen shielding action, and by arranging waveform curved surface on the outer surface of described conductor shield cross section, this waveform curved surface can significantly improve shielding properties, and this corrugated curved surface will improve about 30%-40% than the shielding properties of the screen of plane.
2, simultaneously, be still provided with net metal screen in the outer protection cover that the utility model provides, the utility model can be made to have superhigh shielded performance;
3, this use new structure is simple, rationally, practicality is stronger, even if under the state of bending, still has very superior superhigh shielded performance, can meet the occasion that shielding requirements is high.
Accompanying drawing explanation
