Abstract
The utility model provides an electromagnetic-interference-preventing spring including a cap body part, a cap edge part and elastic rubber. The cap body part is in a shell-shaped structure with wave-shaped wrinkles and arc-shaped bosses. The shell-shaped structure is hollow and includes an accommodation space. The elastic rubber is fixed in the accommodation space. The top end of the elastic rubber is protruded outside the plane of the edge of the cap body part. The edge of the cap body part is connected with the cap edge part externally. According to the utility model, by arranging the elastic rubber in the cap body part, the elasticity is increased and the connection of adjacent components becomes firm. And elastic fatigue of material is avoided and the service lifetime is prolonged. At the same time, the wave-shaped wrinkles are arranged on the arc-shaped surface of external part of the cap body part for increasing the specific surface area, so that the anti-radiation area of the electromagnetic-interference-preventing spring is increased. Therefore, the electromagnetic-interference-preventing spring provided by the utility model has a good protecting effect against electromagnetic interference.
Description
Technical field
The utility model relates to and prevents 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 operate as normal 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 influence 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, 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.
With highly universal computer is 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 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 the slit that causes electromagnetic wave to leak easily at joint.
For guaranteeing the complete metallic object structure of computer cabinet, need between adjacent metal sheet material, keep good electrical conductivity by the EMI contact.Anti-electromagnetic interference shell fragment (EMI shell fragment) thus be a kind ofly to be used to strengthen the sheet material contact and to make high-frequency electromagnetic disturb the device of shorted to earth with the fluid-tight engagement slit, it not only can be as the physical support of EMI contact, also possess better elastic simultaneously, therefore can make the framework of cabinet contact more fully, durable with side sheet room.
Yet relevant anti-electromagnetic interference shell fragment is subjected to the performance limitations of shell fragment manufacturing materials, 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 influence its protection effect for electromagnetic interference.
The utility model content
At the above-mentioned defective and the problem of the too high electromagnetic interference shielding weak effect that causes of elasticity deficiency, surface flatness of existing anti-electromagnetic interference shell fragment, the purpose of this utility model provides that a kind of elasticity is higher, specific area is bigger, the anti-electromagnetic interference shell fragment of anti-electromagnetic interference better effects if.
In order to achieve the above object, the utility model provides following technical scheme: a kind of anti-electromagnetic interference shell fragment, it is characterized in that, comprise: cap body, shade portion, elastic caoutchouc, described cap body are the shell-like structures that the surface has waveform wrinkle, cambered surface projection, and its inside is hollow, contain receiving space, be fixed with elastic caoutchouc in the described receiving space, its top protrudes from plane, cap body edge place, external described shade portion 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 installed in respectively on the upper and lower surface of described shade portion.
Preferred as technique scheme, being shaped as of described cap body is spherical.
Preferred as technique scheme, described shade portion is continuous flat ring band shape, and it is located on cap body periphery, and its ring inner surface is connected with cap body edge circumference.
The anti-electromagnetic interference shell fragment that the utility model provides by in cap body inside elastic caoutchouc being set, has not only increased elasticity, makes the connection between the 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.
