Abstract
The utility model relates to a mobile phone radiofrequency shielding cover, solving the problem that the prior mobile phone radiofrequency shielding cover adopts an up-down double-lid structure mode so as to result in complicated structure, high manufacture cost and being inconvenient for radiofrequency chip installation. The utility model provides a mobile phone radiofrequency shielding cover, which comprises a flat cover body, the edge of the cover body is provided with a vertical edge toward one side of the cover body, the cover body is provided with a plurality of through-holes, the vertical edge is provided with a plurality of open slots. The mobile phone radiofrequency shielding cover has single-lid structure mode, simple structure and low manufacture cost; when the radiofrequency chip is welded, the through-hole and the open slot on the mobile phone radiofrequency shielding cover form unidirectional flow channel of hot gas for welding, so as to facilitate the welding of radiofrequency chip and being uneasy to generate false welding.
Description
Technical field
The utility model relates to a kind of electromagnetic screen, more particularly, relates to a kind of mobile phone radio frequency screening cover.
Background technology
Have various functional modules on the mobile phone,, between each functional module mutual electromagnetic interference can not be arranged for guaranteeing the operate as normal of mobile phone, promptly to guarantee not to be subjected to the interference of other functional module, do not disturb other module when self is worked,, all must carry out shielding no matter for which kind of purpose.The electromagnetic radiation of the radio frequency part of mobile phone is very big, must come it is carried out electromagnetic shielding with screening cover.
In existing mobile phone radio frequency screening cover, all be to adopt double-canopy tactic pattern, promptly adopt a loam cake and lower cover, adopt this double-canopy tactic pattern, owing to have loam cake and two screening covers of lower cover, cause the manufacturing cost height, make loam cake and lower cover amalgamation, structure is also complicated, and this double-canopy tactic pattern also is unfavorable for the paster welded and installed of radio frequency chip simultaneously.
The utility model content
The technical problems to be solved in the utility model is, at existing mobile phone radio frequency screening cover manufacturing cost height, complex structure, be unfavorable for the problem of radio frequency chip paster welded and installed, and a kind of simple in structure, low cost of manufacture be provided, be convenient to the mobile phone radio frequency screening cover of radio frequency chip paster welded and installed.
The technical scheme that its technical problem that solves the utility model adopts is: propose a kind of mobile phone radio frequency screening cover, comprise flat lid, described lid edge is provided with vertically to be holded up and towards the vertical edge of lid one side, offer some open-works on the described lid, offer some open slots on the described vertical edge.When the radio frequency chip paster was welded, hot gas entered from the open-work on the lid, and the open slot from vertical edge goes out, and formed one-way flow, was convenient to the welding of chip.Only use a screening cover, simple in structure, can reduce the mobile phone production cost, install also more convenient.
In mobile phone radio frequency screening cover described in the utility model, described lid and vertical edge are structure as a whole.Lid and vertical edge can be bent to form by a sheet metal component punching press when producing, and production technology is simple.
In mobile phone radio frequency screening cover described in the utility model, the vertical edge height at described lid edge is identical.
In mobile phone radio frequency screening cover described in the utility model, described open slot is arranged on the lower limb of vertical edge.
In mobile phone radio frequency screening cover described in the utility model, the arrangement that is square of described open-work, the shape of its arrangement and the profile similarity of radio frequency chip, during radio frequency chip paster welded and installed, open-work is over against the edge of radio frequency chip, and hot blast is blown into from open-work, goes out from open slot, can radio frequency chip be welded easy and conveniently, be difficult for producing rosin joint.
Mobile phone radio frequency screening cover in the utility model has following advantage compared with prior art:
1, the mobile phone radio frequency screening cover in the utility model adopts the version of single lid, and is simple in structure, low cost of manufacture.
2, open-work on the mobile phone radio frequency screening cover and open slot form the one-way flow passage of sweating heat gas, are convenient to the paster welding of radio frequency chip, are difficult for producing rosin joint.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of mobile phone radio frequency screening cover in the utility model.
Embodiment
Fig. 1 shows a more excellent execution mode of the utility model mobile phone radio frequency screening cover.
See also shown in Figure 1ly, mobile phone radio frequency screening cover integral body is a square structure, and it comprises a square tabular lid 1, is provided with contour vertical edge 2 in the edge of lid 1, and vertical edge 2 is towards a side of lid.Offer four open-works 3 that are square and arrange on the lid 1, offer several open slots 4 on the lower limb of vertical edge 2.When the radio frequency chip paster was welded, four open-works 3 of the arrangement that is square were over against four angles of radio frequency chip, and the hot gas of welding usefulness enters from the open-work 3 on the lid 1, open slot 4 from vertical edge 2 goes out, form one-way flow, this welds radio frequency chip easy and conveniently, is difficult for producing rosin joint.Only just can realize the shielding of mobile phone radio frequency with a screening cover, simple in structure, can reduce the production cost of mobile phone, also very convenient when screening cover is installed.
In the mobile phone radio frequency screening cover in the present embodiment, lid 1 is structure as a whole with vertical edge 2, and when making moulding, lid 1 and vertical edge 2 can be bent to form by a sheet metal component punching press, and production technology is simple.
This is square mobile phone radio frequency screening cover in the present embodiment on the whole, in the specific implementation, can make other the convex polygon or the shape of concave polygon as required.
In the present embodiment, the open-work number on the lid 1 is four, and over against four angles of radio frequency chip, when specifically implementing, the number of open-work also can be a plurality of respectively, but preferably can both be on the limit of the maximum external form of radio frequency chip, so that the welding of radio frequency chip.
