Abstract
The utility model discloses an inner antenna structure of a cell phone, comprising an antenna support and an antenna; wherein, the antenna is arranged between the main board and the back cover of the cell phone, and the antenna is attached on the back cover by way of FPC. A spring plate is arranged in the space formed by the main board, the antenna support and the antenna. The central part of the spring plate is fixed onto the antenna support by an attachment way and the two ends of the spring plate elastically contact with the antenna and the main board pad respectively. The utility model can improve the antenna performance, reduce the cost and simplify the assembly technology.
Description
Technical field
The present invention relates to the antenna for mobile phone technology, relate in particular to a kind of built-in antenna of mobile phone structure.
Background technology
In order to adapt to the more and more diversified and more and more succinct requirement of outward appearance of cell-phone function, the built-in antenna of mobile phone structure has replaced external antenna gradually, becomes a kind of development trend of mobile phone.
With reference to figure 1, this figure is a kind of built-in antenna of mobile phone structure comparatively general in the prior art, and as shown in the figure, this structure mainly is made of the antenna 4 that is arranged on the antenna holder 3 between cell phone mainboard 1 and the back cover 2 and be arranged on the antenna holder 3.The shortcoming of this built-in antenna arrangement is, its applied environment is very big to the limitation of antenna performance, and under the bigger situation of effective usable floor area promptly only relatively good at applied environment, antenna, antenna just can reach preferable performance.
In order to overcome the problem that mobile phone antenna performance is subjected to the applied environment influence easily, prior art has also proposed a kind of built-in antenna of mobile phone structure that adopts the spring needle way of contact, with reference to figure 2, in this structure, antenna for mobile phone 4 is with flexible printer circuit (Flexible Printed Circuit, FPC) form is attached on the back cover 2, and in the space that described mainboard 1, antenna holder 3 and antenna 2 form, be provided with a spring needle 5, the back side, syringe needle that the needle stand of this spring needle 5 is seated at mainboard 1 then contact with antenna 2.
Though this structure can utilize effective area to reach the optimization of antenna performance fully, but caused the complicated of the increase of Material Cost and packaging technology simultaneously, usually, the material of above-mentioned second kind of structure and packaging technology cost have increased about 30-50% than first kind of structure.
The utility model content
Technical problem to be solved in the utility model is: a kind of built-in antenna of mobile phone structure is provided, and this structure can save Material Cost, simplify assembly technology when improve the optimization antenna performance.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of built-in antenna of mobile phone structure includes the antenna holder that is arranged between cell phone mainboard and the back cover and is attached to antenna on the back cover with the FPC form, focuses on:
In the space that described mainboard, antenna holder and antenna form, be provided with a shell fragment, the mid portion of this shell fragment is fixed in described antenna holder with the form that attaches, two ends then respectively with described antenna and mainboard pad Elastic Contact.
The beneficial effects of the utility model are:
Embodiment of the present utility model replaces the supporting construction of the prior art medi-spring pin way of contact as antenna by adopting the way of contact of submissile sheet, improves antenna performance thereby not only optimize, and has reduced cost, simplified assembly technology.
Below in conjunction with accompanying drawing the utility model is described in further detail.

Embodiment
With reference to figure 3, the composition structure chart of the embodiment of built-in antenna of mobile phone structure that the utility model provides; As shown in the figure, present embodiment mainly includes the antenna holder 3 that is arranged between cell phone mainboard 1 and the back cover 2 and is attached to antenna 4 on the back cover 2 with the FPC form, and, in the space that described mainboard 1, antenna holder 3 and antenna 4 form, be provided with a shell fragment 6, the mid portion of this shell fragment 6 is fixed in described antenna holder 4 with the form that attaches, two ends then respectively with described antenna 4 and mainboard 1 pad Elastic Contact.
During specific implementation, the two ends of described shell fragment are hook-shaped, and two ends are respectively to contact with mainboard 1 pad with described antenna 4 at the bottom of the hook.
In addition, its length direction protrudes out a boss 41 in antenna holder 4 upper edges, and along protruding out one or more reference columns 411 from this boss perpendicular to the direction of mainboard pad, the pars intermedia division of described shell fragment 6 is provided with corresponding location hole (not shown), and shell fragment 6 is enclosed within on the reference column 411 fixing by location hole.
With reference to figure 4-Fig. 6, in fact, except the supporter of using as fixed antenna, also other functional parts are fixed in conduct to the antenna holder 4 of present embodiment, as the supporter of loudspeaker, camera 7 etc. in mobile phone.For present embodiment more clearly is described, it is sectional front view, end view and the vertical view of reference that Fig. 4-Fig. 6 has provided respectively with antenna holder 4.
Embodiment of the present utility model adopts the way of contact of submissile sheet to replace the supporting construction of the prior art medi-spring pin way of contact as antenna, compare with described spring needle contact structure, the utility model has been simplified assembly technology, can have been saved material and the about altogether 50-60% of assembly cost.
The above is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection range of the present utility model.
