Abstract
The invention discloses a strong electromagnetic pulse shielding protection reinforcing case. The case includes a main board (2), a shielding box body (3), a display shielding cabin (1) and a rear shielding cabin (4). The shielding box body (3) has a rectangular cavity and the front side and the rear side of the shielding box body (3) are connected with the display shielding cabin (1) and the rear shielding cabin (4) fixedly through screws respectively. In a strong electromagnetic pulse environment, strong electromagnetic pulse interference received by the surfaces of the case can be isolated effectively through the display shielding cabin and the rear shielding cabin, so that a problem that electromagnetic pulse interference signals outside the case in the strong electromagnetic pulse environment are led into the case through devices mounted on the outer surface of the case and connection cables of the devices and thus a main board circuit in the shielding box gets damaged is solved.
Description
Technical field
The present invention relates to a kind of shielding protection reinforces cabinet, particularly a kind of strong electromagnetic pulse shielding protection reinforces cabinet.
Background technology
In the past the shielding protection of electronic product reinforced cabinet mainly by the master of front panel, rear board, shielding case body and inside
Plate is constituted.Case front panel and rear board are connected respectively by screw with shielding case body, by adding all kinds of in connection gap
Shielding material, can effectively shield common frequency range electromagnetic wave, prevent it from affecting the normal work of cabinet inside motherboard circuit.But
Under Strong Electromagnetic Pulse, the electromagnetic pulse interference pickup electrode outside cabinet is easily by all kinds of components and parts installed on panel
And its cable of connection internal circuit imports cabinet inside, even burn so as to the motherboard circuit for causing cabinet inside breaks down
Ruin, therefore common shielding protection cabinet cannot realize the effective shielding protection under Strong Electromagnetic Pulse, need to further take and add
Gu safeguard procedures.
The content of the invention
Present invention aim at providing a kind of shielding protection for strong electromagnetic pulse interference reinforces cabinet, strong electromagnetic is solved
Electromagnetic pulse interference signal outside pulse environment lower case imports cabinet inside by panel components and parts and its connection cable, from
And damage the problem of motherboard circuit.
A kind of strong electromagnetic pulse shielding protection reinforces cabinet, including:Mainboard and shielding case body, also include:Show shielding cabin
With rear shielding cabin.Shielding cabin after described, including:Cabin pinboard, rear shielding cabin housing and rear board are shielded afterwards;Shielding cabin is shown,
Including:Conductive shield glass, front panel and display shielding cabin pinboard.Shielding case body sheet as lead welding and shaping rectangular cavities,
Its front and back is connected respectively with display shielding cabin and rear shielding cabin by screw;Rear board is aluminium material thin plate, is had thereon
Element and screw mounting hole, shield afterwards the rectangular cavities that are welded for aluminium sheet of cabin housing, in front and back both sides respectively with rear board
It is fastenedly connected with screw with rear shielding cabin pinboard;Show shielding cabin front panel be aluminium material rectangular frame, frame front with
Conductive shield glass is screwed, and frame rear portion shields cabin pinboard mode connects for screw with showing.
Different degrees of strong electromagnetic pulse irradiation is born on each surface of Strong Electromagnetic Pulse lower case.Above plate framework
Inside is equipped with liquid crystal display, and its cable connects again after display shielding cabin pinboard transfers device interior with the mainboard of cabinet inside
Connect, because cable is transferred into cabinet by the way that pinboard is secondary, cut off the conducting path between cable and mainboard, therefore along liquid crystal
The strong electromagnetic pulse interference signal that screen cable is coupled into is isolated when by showing shielding cabin pinboard, it is impossible to enter cabinet
It is internal.In the same manner, switch, indicator lamp and connector are installed on the rear board that cabin is shielded afterwards, the lead end at each element rear portion is close
After being enclosed in shield cabin housing in, element outgoing cable by after the secondary device interior of transferring of rear shielding cabin pinboard again with cabinet
Internal mainboard connection.Radiate behind cabinet into strong electromagnetic pulse interference ripple by diffraction and conduction enter rear shielding cabin simultaneously
It is coupling on element cable, but elimination is isolated when by rear shielding cabin pinboard, interference signal is connected by element
Wiring cable imports cabinet inside.
The present invention on electromagnetic shielding protection machine box foundation in the past using gap shielding, prevent by the shielding that increased shielding cabin
Shield Design of Reinforcement, the shielding protection for effectively solving the electronic product cabinet under Strong Electromagnetic Pulse reinforces problem.
Description of the drawings
A kind of strong electromagnetic pulse shielding protections of Fig. 1 reinforce cabinet composition figure;
A kind of strong electromagnetic pulse shielding protections of Fig. 2 reinforce the rear shielding cabin of cabinet and show shielding cabin composition figure.
1. show to be shielded behind shielding cabin 5. after the shielding shielding case body 4. of 2. mainboard of cabin 3. and shield cabin after cabin pinboard 6.
9. front panel of housing 7. rear board, 8. conductive shield glass 10. shows shielding cabin pinboard
Specific embodiment
A kind of strong electromagnetic pulse shielding protection reinforces cabinet, including:Mainboard 2 and shielding case body 3, also include:Show shielding
Cabin 1 and rear shielding cabin 4.Described rear shielding cabin 4, including:Cabin pinboard 5, rear shielding cabin housing 6 and rear board 7 are shielded afterwards.Institute
The display shielding cabin 1 stated, including:Conductive shield glass 8, front panel 9 and display shielding cabin pinboard 10.Shielding case body 3 itself
For the rectangular cavities of lead welding and shaping, its forward and backward two sides is connected respectively with display shielding cabin 1 and rear shielding cabin 4 by screw;Below
Plate 7 is aluminium material thin plate, there is element and screw mounting hole thereon, and the rectangular cavity that cabin housing 6 is welded for aluminium sheet is shielded afterwards
Body, in front and back both sides be fastenedly connected with screw with rear board 7 and rear shielding cabin pinboard 5 respectively;Show the front panel 9 in shielding cabin 1
For aluminium material rectangular frame, frame front is screwed with conductive shield glass 8, frame rear portion with show shielding cabin pinboard
10 use mode connects for screw;
Different degrees of strong electromagnetic pulse irradiation is born on each surface of Strong Electromagnetic Pulse lower case.Front panel 9
Lower portion is equipped with liquid crystal display, its cable by show shield cabin pinboard 10 transfer after device interior again with cabinet inside
Mainboard 2 connects, and because cable is transferred into cabinet by secondary, has cut off the conducting path between cable and mainboard 2, therefore along liquid
The strong electromagnetic pulse interference signal that crystalline substance screen cable is coupled into is isolated when by showing shielding cabin pinboard 10, it is impossible to enter
Cabinet inside.In the same manner, switch, indicator lamp and connector, the lead at each element rear portion are installed on the rear board 7 that cabin 4 is shielded afterwards
End is shielded in cabin housing 6, after element outgoing cable is by 5 two device interiors of transferring of rear shielding cabin pinboard after being sealed in
It is connected with the mainboard 2 of cabinet inside again.Radiate behind cabinet into strong electromagnetic pulse interference ripple by diffraction and conduction enter
Shield afterwards and cabin 4 and be coupling on element cable, but elimination is isolated when by rear shielding cabin pinboard 5, make interference signal without
Method imports cabinet inside by component connection wire cable, so as to effectively prevent circuit of the interference signal to the mainboard 2 of cabinet inside
Cause damage.
