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 mobile communication terminal field, in particular a kind of shielding cover device of mobile phone baseband.
Background technology
Mobile phone has multiple functional module, can not mutually disturb; In order to ensure the normal work of mobile phone, electromagnetic shielding must be carried out with screening cover to it.
What at present in cell phone mainboard, a large amount of baseband radio screening cover used all adopted is the metal alloy sheet material compacting of hard.The screening cover of this kind of mode is because screening cover area is comparatively large in the process of carrying out after-sales service, and entirety not easily deforms, and thus needs that whole screening cover is heated to very high temperature and just can take off.Like this, often there will be in order to screening cover is taken off, need cell phone mainboard large area heating repeatedly, thus cause the situation damaging other devices to occur, add 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, for the above-mentioned defect of prior art, provides a kind of shielding cover device of mobile phone baseband, provides that a kind of structure is simple, low cost of manufacture, is convenient to the shielding cover device of mobile phone baseband of manual dismounting.
The technical scheme that technical solution problem of the present invention adopts is as follows:
A kind of shielding cover device of mobile phone baseband, wherein, comprises the net metal lid being provided with multiple grid, and the marginal position of described metal cap body is provided with the welding edge of bending downwards.
Described shielding cover device of mobile phone baseband, wherein, described welding edge adopts subsection setup.
Described shielding cover device of mobile phone baseband, wherein, described welding edge adopts equidistant subsection setup.
Described shielding cover device of mobile phone baseband, wherein, the welding edge height of subsection setup is identical.
Described shielding cover device of mobile phone baseband, wherein, described welding edge is vertical with described metal cap body to be arranged.
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, described metal cap body arranges square, rectangle or circle.
Shielding cover device of mobile phone baseband provided by the present invention, comprise owing to adopting the net metal lid being provided with multiple grid, described welding edge adopts subsection setup; Utilize the characteristic of the softness of wire netting, both met the function of shielding for the signal of telecommunication, when making again manual dismounting screening cover, can weld piecemeal, greatly can improve operability, reduce the probability that mainboard damages, reduce cost.
Accompanying drawing explanation
Fig. 1 is the shielding cover device of mobile phone baseband structural representation that the embodiment of the present invention provides.
Embodiment
For making object of the present invention, technical scheme and advantage clearly, clearly, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.
A kind of shielding cover device of mobile phone baseband that the embodiment of the present invention provides, as shown in Figure 1, it comprises flat metal cap body 100, and described metal cap body 100 adopts network structure, such as, in metal cap body 100, be provided with multiple grid 110.The welding edge 120 of bending is downwards provided with, for welding with Mobile phone PCB at the marginal position of described metal cap body 100.Preferably, described welding edge 120 is vertical with described metal cap body 110 to be arranged, and is structure as a whole, be convenient to install and production technology is simple.
Shielding cover device of mobile phone baseband of the present invention like this, because net metal lid 100 has soft characteristic, had both met the function of shielding for the signal of telecommunication, had been convenient to again manual dismounting screening cover, reduced the damage probability of element.Adopt network structure can also save the material of described metal cap body simultaneously, reduce production cost.
Further, described shielding cover device of mobile phone baseband, as shown in Figure 1, described welding edge 120 adopts subsection setup.Preferably, described welding edge adopts equidistant subsection setup, and the height of its each section of welding edge is set to identical.Like this, shielding cover device of mobile phone baseband of the present invention, when dismounting, utilizes net metal lid 100 to have soft characteristic and the welding edge 120 of subsection setup, can weld piecemeal, greatly can improve operability, reduce the probability that mainboard damages, reduce maintenance cost.
Further, described shielding cover device of mobile phone baseband, wherein, described metal cap body is set to square, rectangle or circle etc.
Shielding cover device of mobile phone baseband provided by the present invention, comprise owing to adopting the net metal lid being provided with multiple grid, described welding edge adopts subsection setup; Utilize the characteristic of the softness of wire netting, both met the function of shielding for the signal of telecommunication, when making again manual dismounting screening cover, can weld piecemeal, greatly can improve operability, reduce the probability that mainboard damages, reduce cost
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection range that all should belong to claims of the present invention.
