Further, described back-up ring is electrically connected to described circuit board by flexible electrical conductors.
Further, described flexible electrical conductors is electric silica gel, conductive glue or five metals shell fragment.
Further, described circuit board, described back-up ring and described metallic support form shielding space, and described chip is arranged in described shielding space.
Further, be provided with heat conductive silica gel between described chip and described metallic support.
Further, on described metallic support, be provided with through hole, described back-up ring is stated through hole around residence.
Further, described circuit board, described back-up ring, described metallic support and described display screen form shielding space, and described chip is arranged in described shielding space.
Further, be provided with heat conductive silica gel between described chip and described display screen.
Further, described metallic support and described back-up ring are integrated the punch forming structure.
The portable mobile termianl that the utility model provides, by back-up ring is set on metallic support, back-up ring surrounds chip, back-up ring plays the effect of shielding to chip, thereby without being separately the chip configuration radome, the heat that chip produces can be directly delivered on metallic support, has accelerated the radiating efficiency of chip, has improved the heat dispersion of portable mobile termianl; And, use radome owing to saving, reduced the thickness of radome, reduced the thickness of portable mobile termianl.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation that Fig. 1 is the utility model portable mobile termianl embodiment.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
As shown in Figure 1, the present embodiment portable mobile termianl, comprise casing 1, metallic support 2, circuit board 3 and display screen 4, metallic support 2 and circuit board 3 are arranged in casing 1, display screen 4 is fixed in casing 1 by metallic support 2, be provided with chip 31 on circuit board 3, be provided with back-up ring 21 on metallic support 2, back-up ring 21 surrounds chip 31.
Particularly, be provided with back-up ring 21 on metallic support 2 in the present embodiment portable mobile termianl, back-up ring 21 surrounds the chip 31 on circuit board 3, by 21 pairs of chips 31 of back-up ring, shielded, realization is without additionally increasing radome on circuit board 3 again, save the gauge of radome, realized reducing the integral thickness of the present embodiment portable mobile termianl.And, because the outside of chip 31 does not have radome to block, the heat that chip 31 produces can directly dissipate by metallic support 2, accelerated the radiating rate of chip 31, improved the heat dispersion of the present embodiment portable mobile termianl.Preferably, in order to improve shield effectiveness, back-up ring 21 is electrically connected to circuit board 3, and for example: back-up ring 21 is electrically connected to circuit board 3 by flexible electrical conductors 22, and flexible electrical conductors 22 can be electric silica gel, conductive glue or five metals shell fragment.
Wherein, the mode shielded by 21 pairs of chips 31 of back-up ring in the present embodiment portable mobile termianl has various ways.For example: form shielding space by circuit board 3, back-up ring 21 and metallic support 2, chip 31 is arranged in this shielding space, and, in order to accelerate the radiating rate of chip 31, is provided with heat conductive silica gel (not shown) between chip 31 and metallic support 2.Perhaps, be provided with through hole on metallic support 2, back-up ring 21 is around living through hole, circuit board 3, back-up ring 21, metallic support 2 and display screen 4 form shielding space, chip 31 is arranged in shielding space, the heat that chip 31 produces passes to metallic support 2 and display screen 4, by metallic support 2 and display screen 4 quick heat radiatings, and is provided with heat conductive silica gel between chip 31 and display screen 4.Preferably, metallic support 2 is integrated the punch forming structure with back-up ring 21.
