Abstract
The invention provides a kind of anti-electromagnetic interference elastic sheet, comprise: cap body, shade portion, elastic caoutchouc, described cap body is the shell-like structure of surface with waveform wrinkle, cambered surface projection, its inside is hollow, containing receiving space, be fixed with elastic caoutchouc in described receiving space, its top protrudes from cap body edge place in plane, external described shade portion of cap body edge place.This anti-electromagnetic interference elastic sheet, by arranging elastic caoutchouc in cap body inside, not only increases elasticity, makes the connection between adjacent component more fastening, and material can be avoided to occur elastic fatigue, increases the service life; Meanwhile, the curved surfaces of cap external body arranges waveform wrinkle to increase specific area, thus increase its radiation proof area.Therefore, anti-electromagnetic interference elastic sheet provided by the invention has better protection effect for electromagnetic interference.
Description
Technical field
The present invention relates to and prevent electromagnetic interference technical field, particularly the anti-electromagnetic interference elastic sheet of one.
Background technology
Can generate electromagnetic waves during electronic component running, the electronic component that these electromagnetic waves normally can work to other forms interference, this phenomenon is called as electromagnetic interference (ElectromagneticInterference, be called for short EMI), its principle is that electromagnetic signal is coupled into another electric network by space radiation or conducting medium by interference source.The impact of EMI radiation is more than that, if human body is in electromagnetic radiation pollution environment for a long time, can produce fatiguability, the ill symptoms such as decrease of memory, physiological function go down.For this reason, US Federal Communication Committee has formulated peremptory norm Electro Magnetic Compatibility (ElectromagneticCompatibility is called for short EMC) standard.
For highly universal computer, during its running, a large amount of EMI radiation can be produced.For reaching EMC standard, computer cabinet must adopt closed conductive shell to shield electromagnetic wave, but considers for dismounting, and housing by forming by relative movement incorporating aspects, so just can only define the gap easily causing electromagnetic wave to leak at joint.
For ensureing the complete metal body structure of computer cabinet, need to keep good electrical conductivity by EMI contact between adjacent metal sheet material.Anti-electromagnetic interference elastic sheet (EMI shell fragment) a kind ofly makes high-frequency electromagnetic disturb the device of shorted to earth for strengthening web contact with fluid-tight engagement gap, it not only can be used as the physical support of EMI contact, also possesses good elasticity, therefore, it is possible to make the framework of cabinet contact more abundant, durable with side sheet room simultaneously.
But relevant anti-electromagnetic interference elastic sheet makes the performance limitations of material by shell fragment, its elasticity is comparatively limited; On the other hand, the surface flatness of relevant anti-electromagnetic interference elastic sheet is too high, and this can affect its protection effect for electromagnetic interference.
Summary of the invention
Elasticity for existing anti-electromagnetic interference elastic sheet is not enough, the above-mentioned defect of too high the caused electromagnetic interference shielding weak effect of surface flatness and problem, the object of this invention is to provide that a kind of elasticity is higher, specific area is larger, the anti-electromagnetic interference elastic sheet of anti-electromagnetic interference better effects if.
In order to achieve the above object, the invention provides following technical scheme: a kind of anti-electromagnetic interference elastic sheet, it is characterized in that, comprise: cap body, shade portion, elastic caoutchouc, described cap body is the shell-like structure of surface with waveform wrinkle, cambered surface projection, and its inside is hollow, containing receiving space, be fixed with elastic caoutchouc in described receiving space, its top protrudes from cap body edge place in plane, external described shade portion of cap body edge place.
Preferred as technique scheme, the vertical sectional shape of described cap body is corrugated camber line.
Preferred as technique scheme, also comprise holding section, it is arranged on the upper and lower surface in described shade portion respectively.
Preferred as technique scheme, the shape of described cap body is spherical.
Preferred as technique scheme, described shade portion is that continuous print flat ring is banded, and it is peripheral that it is located on cap body, and its ring inner surface is connected with cap body edge place circumference.
Anti-electromagnetic interference elastic sheet provided by the invention, by arranging elastic caoutchouc in cap body inside, not only increases elasticity, makes the connection between adjacent component more fastening, and material can be avoided to occur elastic fatigue, increases the service life; Meanwhile, the curved surfaces of cap external body arranges waveform wrinkle to increase specific area, thus increase its radiation proof area.Therefore, this anti-electromagnetic interference elastic sheet has better protection effect for electromagnetic interference.
Accompanying drawing explanation
