Description
Technical field
The utility model belongs to ELECTROMAGNETIC RADIATION SHIELDING field, and in particular to a kind of electric field radiation shielding tape.
Background technology
In accurate electromechanical equipment, carry out shielding design is generally required, but the seam meeting that mating surface is formed between casing
Cause shield conductive discontinuous, generate electromagnetic leakage, and internal electromagnetic signal can directly by into and out of at air port to space
Radiation so that product cannot reach the requirement of relative electric fields radiation intensity limitation.The conductive coating that existing shielding design uses
The plastic foam shield effectiveness of cloth is poor, and conductive rubber pad needs additional headspace and clamping structure, and cost is quite high.
Utility model content
The purpose of this utility model is to provide a kind of electric field radiation shielding tape, and the shield effectiveness of the adhesive tape is good, small,
Can with patch with.
Technical solution is used by the utility model：
A kind of electric field radiation shielding tape, the middle part of adhesive tape is masked segment, both sides are bonding portion, and masked segment is folding
Folded and/or wound multilayer screen band, bonding portion are the splicing tape of individual layer, and shielding band is followed successively by conductive substrates in thickness direction
Layer, pressure-sensitive adhesive layer and magnetosphere, splicing tape are followed successively by conductive basal layer and pressure-sensitive adhesive layer, adjacent two layers shielding band in thickness direction
Form a shading ring.
Further, at least there are two shading rings in a thickness direction for masked segment.
Further, conductive basal layer is the copper foil of 0.02-0.2mm thickness.
Further, magnetosphere is nano ferriferrous oxide powder of the coating thickness in more than 0.05mm.
The beneficial effects of the utility model are：
In use, the pressure-sensitive adhesive layer that external force acts on bonding portion fixes entire adhesive tape bonding so that masked segment pastes
Conjunction is covered in seam crossing and into and out of at air port, when the interference electromagnetic signal that electric field radiation generates travels to masked segment, screen
The conductive substrate for covering the annular on ring generates vortex under interference signal magnetic fields, is vortexed the counter magnetic field of generation and interference magnetic field
Offset, while diamagnetism in the magnetosphere on shading ring and makes magnetic layer, magnetospheric magnetic field and interference magnetic field into
One step is offset, and is converted into heat and is dispersed into environment, and the interference electromagnetism which can be generated with effective attenuation electric field radiation is believed
The leakage of number (more than 100KHz), relatively existing conducting foam, conductive rubber pad have better shield effectiveness, small, energy
With patch with, can preferably gap-bridging device gap, also can quickly be applied in experiment field.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figures 1 to 4, a kind of electric field radiation shielding tape, the middle part of adhesive tape is masked segment 2, both sides are bonding
Portion 1 divides, and masked segment 2 is folding and/or the multilayer screen band of wound, and bonding portion 1 is the splicing tape of individual layer, and shielding band is in thickness
Degree direction is followed successively by conductive basal layer 3, pressure-sensitive adhesive layer 4 and magnetosphere 5, and splicing tape is followed successively by conductive basal layer 3 in thickness direction
With pressure-sensitive adhesive layer 4, adjacent two layers shielding band forms a shading ring 6.
As shown in figure 5, in use, the pressure-sensitive adhesive layer 4 that external force acts on bonding portion fixes entire adhesive tape bonding so that
Masked segment 2 is fitted in seam crossing and into and out of at air port, when the interference electromagnetic signal that electric field radiation generates travels to screen
When covering part, the conductive substrate 3 of the annular on shading ring 6 generates vortex under interference signal magnetic fields, is vortexed the anti-of generation
Magnetic field and interference magnetic field cancellation, while diamagnetism in the magnetosphere 5 on shading ring and makes magnetic layer, magnetosphere 5
Magnetic field is further offset with interference magnetic field, and is converted into heat and is dispersed into environment, which can be with effective attenuation internal interference
The leakage of electromagnetic signal (more than 100KHz), relatively existing conducting foam, conductive rubber pad have better shield effectiveness, and body
Product significantly reduction, with patch with, can preferably gap-bridging device gap, also can quickly be applied in experiment field.
In the present embodiment, at least there are two shading ring 6, shading ring more than 6, shieldings in a thickness direction for masked segment 2
Effect is better.
In the present embodiment, conductive basal layer 3 is the copper foil of 0.02-0.2mm thickness, and copper foil conductive effect is good, rapid heat dissipation.
In the present embodiment, magnetosphere 5 is coating thickness in the nano ferriferrous oxide powder of more than 0.05mm, nanometer four
The eddy current effect of Fe 3 O is good.
It should be appreciated that for those of ordinary skills, can be improved or converted according to the above description,
And all these modifications and variations should all belong to the protection domain of the appended claims for the utility model.
