The electromagnetic shielding case is light in weight, capable of achieving radiating on electronic elements, good in shielding effect, easy to operate and convenient to install.
Description
Technical field
The present invention relates to a kind of electro-magnetic shielding cover.
Background technology
Electro Magnetic Compatibility EMC(Electromagnetic Compatibility) refer to that electronic equipment neither disturbs other equipment, also be not subjected to the impact of other equipment simultaneously; Electronic component interference to external world, be called EMI (Electromagnetic Interference); Electromagnetic wave can with the electronic component effect, produce disturbed phenomenon, be called EMS(Electromagnetic Susceptibility).
Because shield all plays and absorbs energy (eddy current loss), reflected energy (electromagnetic wave is at the boundary reflection on shield) and counteracting energy (electromagnetic induction produces reverse electromagnetic field on screen the interference electromagnetic wave from outsides such as wire, cable, component, circuit or systems and internal electrical magnetic wave, can offset part and disturb electromagnetic wave) effect, so shield has the function that weakens interference.
Existing radome is on mask frame, to add a screening cover, directly covers on the top of electronic component, and to reach the effect of electromagnetic shielding, but existing radome is not considered electronic element radiating and the problem that alleviates the weight of radome own.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, provide a kind of lightweight, can be to electronic element radiating and the good electro-magnetic shielding cover of shield effectiveness.
For achieving the above object, the technical solution used in the present invention is: a kind of electro-magnetic shielding cover, it is characterized in that: comprise square screening cover and the shielding wall that is arranged on described screening cover periphery, described screening cover is provided with several louvres, described shielding wall is provided with the butting section of horizontal bending laterally, on described butting section and screening cover, is equipped with several cable-through holes.
In a preferred embodiment of the present invention, further comprise the two ends of described louvre regular distribution at described screening cover, described screening cover is provided with two monitoring windows, described one of them monitoring window is arranged on an end margin place of described screening cover, and another monitoring window is arranged on the side of the louvre on the described screening cover other end.
In a preferred embodiment of the present invention, comprise that further described screening cover wherein is inclined-plane between a lateral edges and described shielding wall, and be provided with from described screening cover edge extend to described inclined-plane, the heat radiation hole of shielding wall and butting section.
In a preferred embodiment of the present invention, comprise that further the described butting section that is provided with the heat radiation hole is provided with three described cable-through holes, described heat radiation hole is separately positioned between two adjacent described cable-through holes.
In a preferred embodiment of the present invention, comprise that further the described Shang Yanqi edge, butting section that is provided with the heat radiation hole is provided with three engaging grooves of the described cable-through hole of subtend respectively.
In a preferred embodiment of the present invention, the drift angle that further comprises described each butting section is fillet.
The invention solves the defect existed in background technology, electro-magnetic shielding cover of the present invention is lightweight, can be good to electronic element radiating and shield effectiveness, and simultaneously simple to operate, easy for installation.
The accompanying drawing explanation
The present invention is further described below in conjunction with drawings and Examples.

In figure: 10, screening cover, 11, louvre, 20, the shielding wall, 30, butting section, 40, cable-through hole, 50, detection window, 60, inclined-plane, 70, the heat radiation hole, 80, the engaging groove, 90, fillet.
Embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only shows the formation relevant with the present invention.
As shown in Figure 1, a kind of electro-magnetic shielding cover, comprise square screening cover 10 and the shielding wall 20 that is arranged on screening cover 10 peripheries, screening cover 10 is provided with several louvres 11, shielding wall 20 is provided with on the 30， butting section 30, butting section of horizontal bending laterally and screening cover 10 and is equipped with several cable-through holes 40; Louvre 11 regular distribution are at the two ends of screening cover 10, screening cover 10 is provided with two monitoring windows 50, one of them monitoring window 50 is arranged on an end margin place of screening cover 10, and another monitoring window 50 is arranged on the side of the louvre 11 on screening cover 10 other ends; Screening cover 10 a wherein lateral edges and shielding be inclined-plane 60 between wall 20, and is provided with the heat radiation hole 70 that self-shileding lid 10 edges extend to inclined-plane 60, shield wall 20 and butting section 30; The butting section 30 that is provided with heat radiation hole 70 is provided with three cable-through holes 40, and heat radiation hole 70 is separately positioned between two adjacent cable-through holes 40; Be provided with on the butting section 30 of heat radiation hole 70 and along its edge, be provided with three respectively engaging grooves 80 of subtend cable-through holes 40; In the present invention, the drift angle of each butting section 30 is fillet 90, to prevent sharp-pointed angle scratch operating personnel.
The invention has the beneficial effects as follows:
1, on the two ends of screening cover, louvre is set, electromagnetic wave leakage in radome can be gone out on the one hand, also can prevent that extraneous electromagnetic wave from entering and producing interference, on the other hand, be conducive to distribute in radome the heat produced when electronic component is worked, also alleviated the weight of protective cover simultaneously;
2, the butting section of level is set, can be pressed on circuit board; The engaging groove is set on butting section, is convenient to engage with circuit board, simple to operate, easy for installation;
3, in like manner, the heat radiation hole is set on inclined-plane and butting section, the dissipation of heat produced in the time of can more effectively electronic component on circuit board being worked is gone out, and has also alleviated the weight of radome simultaneously.
Above foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related personnel can, in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on specification, must determine technical scope according to the claim scope.
