Abstract
The invention provides an electromagnetic interference prevention spring plate which comprises a cap body portion, a cap brim portion and elastic rubber, wherein the cap body portion is in a shell-shaped structure, the surface of the structure is provided with weave-shaped creases and a protruding arc face, the cap body portion is hollow, a containing space is arranged inside the cap body portion, the elastic rubber is fixed in the containing space, the top end of the containing space protrudes out of a plane where the edge of the cap body portion is located, and the edge of the cap body portion is externally connected with the cap brim portion. According to the electromagnetic interference prevention spring plate, the elastic rubber is arranged inside the cap body portion, not only is elasticity increased and is connection between adjacent components firm, but also materials can be prevented from producing elastic fatigue and service life is prolonged; and meanwhile, an arc-shaped surface outside the cap body portion is provided with the weave-shaped creases to increase a specific surface area, and therefore the radiation protection area of the electromagnetic interference prevention spring plate is increased. Therefore, the electromagnetic interference prevention spring plate has good protection effects on electromagnetic interference.
Description
Technical field
The present invention relates to prevent the electromagnetic interference technical field, particularly a kind of anti-electromagnetic interference shell fragment.
Background technology
Can generate electromagnetic waves during the electronic component running, these electromagnetic waves can form the electronic component of other normal operation and disturb, this phenomenon is called as electromagnetic interference (Electromagnetic Interference, be called for short EMI), its principle is that interference source is coupled into another electric network by space radiation or conducting medium with electromagnetic signal.The impact of EMI radiation is more than that, if human body is in the electromagnetic radiation pollution environment for a long time, can produce fatiguability, decrease of memory, the physiological function ill symptoms such as go down.For this reason, US Federal Communication Committee has formulated peremptory norm Electro Magnetic Compatibility (Electromagnetic Compatibility is called for short EMC) standard.
Take highly universal computer as example, can produce a large amount of EMI radiation during its running.For reaching the EMC standard, computer cabinet must adopt the sealing conductive shell with the shielding electromagnetic wave, but considers for dismounting, and housing can only be combined by the part that can relatively move, and has so just formed at joint the gap that easily causes electromagnetic wave to leak.
For guaranteeing the complete metallic object structure of computer cabinet, need to pass through the good electrical conductivity of EMI holding contact between adjacent metal sheet material.Anti-electromagnetic interference shell fragment (EMI shell fragment) thus be a kind ofly to make high-frequency electromagnetic disturb the device of shorted to earth for strengthening the sheet material contact with the fluid-tight engagement gap, it not only can be as the physical support of EMI contact, therefore also possess simultaneously good elasticity, can make the framework of cabinet contact more fully with side sheet room, durable.
Yet relevant anti-electromagnetic interference shell fragment is subjected to shell fragment to make the performance limitations of material, and its elasticity is comparatively limited; On the other hand, the surface flatness of relevant anti-electromagnetic interference shell fragment is too high, and this can affect it for the protection effect of electromagnetic interference.
Summary of the invention
Elasticity for existing anti-electromagnetic interference shell fragment is not enough, defects and the problem of the too high electromagnetic interference shielding weak effect that causes of surface flatness, the purpose of this invention is to provide that a kind of elasticity is higher, specific area is larger, the anti-electromagnetic interference shell fragment 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 shell fragment, it is characterized in that, comprise: cap body, shade section, elastic caoutchouc, described cap body be the surface with the shell-like structure of waveform wrinkle, cambered surface projection, its inside is hollow, contain receiving space, be fixed with elastic caoutchouc in described receiving space, its top protrudes from plane, cap body edge place, external described shade section of cap body edge.
Preferred as technique scheme, the vertical sectional shape of described cap body is corrugated camber line.
Preferred as technique scheme also comprises the holding section, and it is arranged on respectively on the upper and lower surface of described shade section.
Preferred as technique scheme, being shaped as of described cap body is spherical.
Preferred as technique scheme, described shade section is that continuous flat ring is banded, and it is peripheral that it is located on the cap body, and its ring inner surface is connected with cap body edge circumference.
Anti-electromagnetic interference shell fragment provided by the invention by in cap body inside, elastic caoutchouc being set, has not only increased elasticity, makes the connection between adjacent component more fastening, and can avoid material elastic fatigue to occur, increases the service life; Simultaneously, the waveform wrinkle are set with the increase specific area on the curved surfaces of cap external body, thereby have increased its radiation proof area.Therefore, this anti-electromagnetic interference shell fragment has better protection effect for electromagnetic interference.
