Abstract
The invention relates to the field of mobile communication terminals and discloses a shielding cover device of a mobile phone baseband. The shielding cover device of the mobile phone baseband comprises a reticular metal cover body with a plurality of grids thereon, wherein the edge position of the metal cover body is provided with a welding side which is bent downwards; and the welding side is segmented. When the shielding cover device of the mobile phone baseband is adopted, due to the reticular metal cover body with the plurality of grids thereon and the segmented welding side, by means of the soft characteristics of a metal mesh, the function of shielding electric signals is conducted and the shielding cover can be welded piecewise when disassembled and assembled manually. Therefore, the operability is greatly improved, the damage rate of a main board is reduced, and the cost is reduced.
Description
Technical field
The present invention relates to the mobile communication terminal field, in particular a kind of shielding cover device of mobile phone baseband.
Background technology
Have a plurality of functional modules on the mobile phone, can not the phase mutual interference; In order to guarantee the operate as normal of mobile phone, must come it is carried out electromagnetic shielding with screening cover.
What a large amount of base band radio shielding lids that use all adopted in cell phone mainboard at present is the metal alloy sheet material compacting of hard.Because the screening cover area is bigger, and integral body is difficult for deforming the screening cover of this class mode in the process of carrying out after-sales service, thereby whole screening cover need be heated to very high temperature and just can take off.Like this, appeared as through regular meeting screening cover has been taken off, need be to cell phone mainboard large tracts of land heating repeatedly, thus the situation that causes damaging other devices occurs, and has increased maintenance cost.
Therefore, prior art has yet to be improved and developed.
Summary of the invention
The technical problem to be solved in the present invention is that the above-mentioned defective at prior art provides a kind of shielding cover device of mobile phone baseband, a kind of simple in structure, low cost of manufacture is provided, has been convenient to the shielding cover device of mobile phone baseband of manual dismounting.
The technical scheme that technical solution problem of the present invention is adopted is as follows:
A kind of shielding cover device of mobile phone baseband wherein, comprises that it is provided with the net metal lid of a plurality of grids, and the marginal position of described metal cap body is provided with the welding edge of downward bending.
Described shielding cover device of mobile phone baseband, wherein, described welding edge adopts the segmentation setting.
Described shielding cover device of mobile phone baseband, wherein, described welding edge adopts equidistant segmentation setting.
Described shielding cover device of mobile phone baseband, wherein, the welding edge height that segmentation is provided with is identical.
Described shielding cover device of mobile phone baseband, wherein, described welding edge is provided with described metal cap body is vertical.
Described shielding cover device of mobile phone baseband, wherein, described welding edge and described metal cap body are structure as a whole.
Described shielding cover device of mobile phone baseband, wherein, that described metal cap body is provided with is square, rectangle or circle.
Shielding cover device of mobile phone baseband provided by the present invention comprises that it is provided with the net metal lid of a plurality of grids owing to adopt, and described welding edge adopts the segmentation setting; Utilize the soft characteristic of wire netting, both satisfied function of shielding, when making manual dismounting screening cover again, can weld piecemeal, can improve operability greatly, reduce the probability that mainboard damages, reduced cost for the signal of telecommunication.
Description of drawings
Fig. 1 is the shielding cover device of mobile phone baseband structural representation that the embodiment of the invention provides.
Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, clear and definite, below develop simultaneously with reference to accompanying drawing that the present invention is described in more detail for embodiment.
A kind of shielding cover device of mobile phone baseband that the embodiment of the invention provides, as shown in Figure 1, it comprises flat metal cap body 100, and described metal cap body 100 employing network structures, for example metal cap body 100 is provided with a plurality of grids 110.Be provided with the welding edge 120 of downward bending at the marginal position of described metal cap body 100, be used for welding with the mobile phone pcb board.Preferably, described welding edge 120 and described metal cap body 110 vertical settings, and be structure as a whole, it is simple to be convenient to installation and production technology.
Shielding cover device of mobile phone baseband of the present invention like this because net metal lid 100 has soft characteristic, has both satisfied the function of shielding for the signal of telecommunication, is convenient to manual dismounting screening cover again, has reduced the damage probability of element.Adopt network structure can also save the material of described metal cap body simultaneously, reduced production cost.
Further, described shielding cover device of mobile phone baseband, as shown in Figure 1, described welding edge 120 adopts the segmentation setting.Preferably, described welding edge adopts equidistant segmentation setting, and the height of its each section welding edge is set to identical.Like this, shielding cover device of mobile phone baseband of the present invention utilizes net metal lid 100 to have the welding edge 120 of soft characteristic and segmentation setting when dismounting, can weld piecemeal, can improve operability greatly, reduce the probability that mainboard damages, reduce maintenance cost.
Further, described shielding cover device of mobile phone baseband, wherein, that described metal cap body is set to is square, rectangle or circle etc.
Shielding cover device of mobile phone baseband provided by the present invention comprises that it is provided with the net metal lid of a plurality of grids owing to adopt, and described welding edge adopts the segmentation setting; Utilize the soft characteristic of wire netting, both satisfied function of shielding, when making manual dismounting screening cover again, can weld piecemeal, can improve operability greatly, reduce the probability that mainboard damages, reduced cost for the signal of telecommunication
Should be understood that application of the present invention is not limited to above-mentioned giving an example, for those of ordinary skills, can be improved according to the above description or conversion that all these improvement and conversion all should belong to the protection range of claims of the present invention.
