Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of protection of the invention.
According to embodiments of the invention, provide a kind of grid.
As shown in Figure 1, electromagnetic screening grid portion 1 and composite material grid portion 2 is comprised according to the grid of the embodiment of the present invention, wherein, composite material grid portion 2 is covered in the part surface in electromagnetic screening grid portion 1, composite material grid portion 2 and electromagnetic screening grid portion 1 form at least one parting bead (such as, example as shown in Figure 1, comprises parting bead 31 and parting bead 32), electromagnetic screening grid portion is made up of the material with electro-magnetic screen function.
Wherein, electromagnetic screening grid portion is by one of at least making in following material: metal, alloy, carbon fiber.By means of above-mentioned material or its combination, electromagnetic screening grid can play the effect of electromagnetic screening, as required, choose reasonable can form the material in electromagnetic screening grid portion, thus shielding action is played to the electromagnetic wave of wavelength in particular range (frequency), such as, the material in electromagnetic screening grid portion can be selected, the effect of the longer low-frequency electromagnetic wave of shielding wavelength can be played.
The present invention avoids the grid adopting all-metal to make, but obtain grid adopting composite material to process with the mode of combination of materials with electro-magnetic screen function, thus enough mechanical strengths can be provided by electromagnetic shielding material and composite material, the weight of grid can also be reduced simultaneously.In addition, because above-mentioned grid has exposed electromagnetic shielding material (such as, when adopting metal to form electromagnetic screening grid portion, having that part metals is exposed to be covered by composite material grid portion outside and not), therefore, it is possible to provide the function of reflection of electromagnetic wave.
In one embodiment, the part surface in electromagnetic screening grid portion 1 can be fixed in composite material grid portion 2 by the mode of pressing.In other embodiments, the part surface in electromagnetic screening grid portion 1 can be fixed on by other means in composite material grid portion 2, comprises bonding, welding, plating, sputtering, spraying or fastener fixing etc.Plated metal or alloy are also passable on the composite.
In addition, the material that can adopt in composite material comprises resin, and this resin can comprise thermosetting resin and/or thermoplastic base resin.
