Background

The antenna of the mobile phone is developed and designed in a plurality of modes, wherein the scheme of using the antenna for sticking the FPC is more, and the mode of saving the cost is also more. How to effectively protect the FPC antenna is particularly important in a compact inner space of the mobile phone.

At present, the FPC antenna of the mobile phone is generally positioned on the inner walls of a shell at the head and the bottom of the mobile phone and covers the design mode of four corners; because the inner space of the mobile phone is limited, the gap between the FPC antenna pasted on the inner wall of the rear shell and the front shell is only 0.2mm, and the gap is very small; the mobile phone adopts the FPC antenna scheme, the rear shell only can use a plastic shell or a non-metal shell, the strength is weak, and in order to consider the antenna performance and increase the FPC antenna area, only the FPC antenna can be adhered to the inner wall of the rear shell and cover the corner area; above design, because cell-phone casing intensity is limited to antenna protection and dodge the space, lead to the cell-phone to receive impact deformation or fracture easily at the in-process FPC antenna that falls to lead to cell-phone antenna function to receive the influence or directly become invalid.

SUMMERY OF THE UTILITY MODEL

In order to overcome the problem, the utility model provides a simple structure, and can effectively protect the FPC antenna, make the cell-phone when falling, the FPC antenna can not directly receive the impact and influence the FPC antenna structure of the cell-phone of function.

The technical scheme of the utility model is that: the utility model provides a FPC antenna structure of cell-phone, includes cell-phone backshell, FPC antenna and preceding shell, preceding shell with the cell-phone backshell is connected, the FPC antenna is established preceding shell with between the backshell, the laminating of FPC antenna is in on the inner wall of cell-phone backshell, still include a plurality of protection muscle, a plurality of the protection muscle is established on the inner wall of backshell, correspond a plurality of on the FPC antenna protection muscle department is equipped with corresponding through-hole, a plurality of the protection muscle passes a plurality of on the FPC antenna the through-hole with preceding shell butt, the height of protection muscle is greater than the thickness of FPC antenna.

To the utility model discloses an improve, the height of protection muscle is greater than the thickness of FPC antenna is for selecting between 0.2 mm-0.05 mm.

To the improvement of the utility model, the protection rib is cuboid or/and cylindrical.

To the utility model discloses an improve, a plurality of the protection muscle with the cell-phone backshell is integrated into one piece.

The utility model discloses owing to adopted including cell-phone backshell, FPC antenna and preceding shell, preceding shell with the cell-phone backshell is connected, the FPC antenna is established preceding shell with between the backshell, the laminating of FPC antenna is in on the inner wall of cell-phone backshell, still include a plurality of protection muscle, a plurality of the protection muscle is established on the inner wall of backshell, correspond a plurality of on the FPC antenna protection muscle department is equipped with corresponding through-hole, a plurality of the protection muscle passes a plurality of on the FPC antenna the through-hole with preceding shell butt, the height of protection muscle is greater than the structure of the thickness of FPC antenna, the utility model has the advantages of simple structure, and can effectively protect the FPC antenna, make the cell-phone when falling, the FPC antenna can not directly receive the impact and influence the function.

Detailed Description

In the description of the present invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or assembly referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may for example be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the two components can be directly connected or indirectly connected through an intermediate medium, and the two components can be communicated with each other. The specific meaning of the above terms in the present invention can be understood in specific cases for those skilled in the art.

Please refer to fig. 1 to 4, what fig. 1 to 4 disclose is an FPC antenna structure of a mobile phone, which includes a mobile phone rear case 1, an FPC antenna 2 and a front case 3, the front case 3 is connected with the mobile phone rear case 1, the FPC antenna 2 is disposed between the front case 3 and the rear case, the FPC antenna 2 is attached to the inner wall of the mobile phone rear case 1, and further includes a plurality of protection ribs 4, the plurality of protection ribs 4 are disposed on the inner wall of the rear case, corresponding through holes 21 are disposed on the FPC antenna 2 corresponding to the plurality of protection ribs 4, the plurality of protection ribs 4 penetrate through the plurality of through holes 21 on the FPC antenna 2 to abut against the front case 3, and the height of the protection ribs 4 is greater than the thickness of the FPC antenna 2. According to the layout of the FPC antenna 2 and the space of the inner shell, the effective protection ribs 4 are added, and the inner protection ribs 4 can firstly unload the impact force when the mobile phone falls, so that the effect of protecting the FPC antenna 2 is achieved.

Preferably, the height of the protection rib 4 is selected to be 0.2mm to 0.05mm larger than the thickness of the FPC antenna 2. At present, the mobile phone pursues more functions, therefore, the structure of the inside of the mobile phone is more compact, there is not too much space, the height of the protection rib 4 is greater than the thickness of the FPC antenna 2 is 0.08mm as the optimal choice, so that when the mobile phone falls and is impacted, the convex protection rib 4 is impacted at first, the force unloading effect is achieved, and the FPC antenna 2 piece can not be impacted directly due to the deformation of the shell in the falling process.

Preferably, the protective rib 4 is rectangular or/and cylindrical.

Preferably, the plurality of protective ribs 4 and the mobile phone rear shell 1 are integrally formed.
