Based on above-mentioned mobile terminal hardware configuration and communication system, each embodiment of the method for the present invention is proposed.
The embodiment of the invention provides a kind of mask frames, as shown in figure 5, the front frame 300 or gold of the mask frame 200 and terminal
Belong to and is provided with one or more first convex closure 500 on the side that rear cover 400 contacts.
Wherein, mask frame 200 is using punch forming.
Wherein, second be arranged in the front frame 300 or metal back cover 400 of the first convex closure 500 in mask frame 200 and terminal
Convex closure 600 forms sawtooth occlusion structure to increase electric continuity.
Optionally, the first convex closure 500 is semicircle, triangle or rectangular.
Optionally, the height of the first convex closure 500 is greater than or equal to 1 millimeter and is less than or equal to 2 millimeters.Wherein, first is convex
The derivation process of the value range of the height of packet 500 is as follows:
Firstly, by v=λ f (wherein, v is velocity of wave, and λ is wavelength, and f is frequency), it is known that λ=v/f, secondly, f is set as
Triple-frequency harmonics, that is, 3GHz triple-frequency harmonics of highest frequency；Finally, due to which v is therefore a constant can calculate the big of λ/20
General value is 1.8 millimeters, therefore rule of thumb the height of the first convex closure 500 can be set greater than or is equal to 1 millimeter
And it is less than or equal to 2 millimeters.It should be noted that highest frequency specific value is that those skilled in the art according to the actual situation may be used
With what is determined, 3GHz is not used to limit the protection scope of the application here, and details are not described herein again.
Wherein, when semicircle is elliptical half, the height of the first convex closure 500 is an elliptical axis (short axle or long axis)
Half, that is, Fig. 6 (a) in H1, the length of convex closure 500 is length, that is, Fig. 6 (a) of another elliptical axis (long axis or short axle)
In L1 (wherein it is possible to by ellipse, to be limited to the ratio of the radius of elliptical short axle and the radius of elliptical long axis be two to three,
It can also be limited to other ratios)；When the first convex closure 500 is rectangular, the height of the first convex closure 500 is that rectangular height is
H2 in Fig. 6 (b), the length of the first convex closure 500 are the L2 in rectangular length, that is, Fig. 6 (b)；When the first convex closure 500 is triangle
When shape, as shown in Fig. 6 (c), H3 is the height of triangle, and L3 is the length of triangle.
It should be noted that other than above-mentioned shape that the application mentions (semicircle, triangle or rectangular), it is other can be with
Also within the scope of protection of this application, details are not described herein again for the shape of the convex closure of formation sawtooth occlusion structure.
Optionally, when the first convex closure 500 is two or more, between two the first convex closures 500 of arbitrary neighborhood
Distance be less than or equal to the first convex closure 500 height.As shown in figure 5, L4 be arbitrary neighborhood two the first convex closures 500 it
Between distance (and length of the second convex closure 600).It should be noted that between two the first convex closures 500 of arbitrary neighborhood
Distance is less than or equal to the height of the first convex closure 500, can be realized and more first convex closures 500 are arranged in mask frame 200, thus
It preferably ensure that electric continuity.
Wherein, the number for the first convex closure 500 being arranged in mask frame 200 is by the length of the first convex closure 500, arbitrary neighborhood
The length for the side that the distance between two first convex closures 500 and the mask frame are contacted with the front frame of terminal or metal back cover is true
It is fixed.Such as: the length for the side that mask frame 200 and the mask frame 200 are contacted with the front frame 300 of terminal or metal back cover 400 is
24 millimeters, it is assumed that the height of the first convex closure is 2 millimeters, and length is 4 millimeters, between two the first convex closures 500 of arbitrary neighborhood
