Son, the roof 4 of cover body 2 is equivalent to roof, and the wall 6 that connects of roof 4 surrounding is equivalent to house surrounding
Wall, connects wall 6 and is then equivalent to ground, play fixing effect, make cover body 2 be fixed on printed circuit
On plate 1.
Further, the above-mentioned parting bead 3 being previously mentioned is as it is shown in figure 1, this parting bead 3 is for by the sky in cover body 2
Between be divided into multiple cavity, and the quantity of cavity is identical with the quantity of circuit module, and one_to_one corresponding,
And the space in each cavity is slightly larger than circuit module, to facilitate receiving circuit module.Cavity is as one
Booth, separates the circuit module covered with other adjacent circuit modules, and each circuit module has
One relatively independent space, is isolated from each other between each circuit module, is effectively prevented electromagnetism and does
Disturb.
Secondly, in the present embodiment, sidewall 5 and connect wall 6 and stretch out institute's shape for roof 4 surrounding
The extension bending become is constituted, and connects wall 6 and is parallel to each other with roof 4, and roof 4 and printed circuit board (PCB)
1 is parallel, connects wall 6 and is parallel to printed circuit board (PCB) 1 bonded to each other with printed circuit board (PCB) 1, thus has
It is beneficial to connect the fixing of wall 6 and printed circuit board (PCB) 1.And sidewall 5 and roof 4 are mutually perpendicular to, i.e. sidewall
5 are perpendicular to printed circuit board (PCB) 1, thus are conducive to being supported radome entirety.
It addition, it is noted that connection wall 6 is general outside cover body 2, connect wall 6 as roof 4
Stretch out and a part for the bending section parallel with printed circuit board (PCB) 1, the direction folding outside cover body 2
Curved, i.e. connect wall 6 outer visual at cover body 2, so can reduce and take space in cavity, simultaneously facilitate
Connect the fastening of wall 6 and printed circuit board (PCB) 1.Connecting wall 6 can also be in cover body 2, i.e. towards cover body
Direction bending in 2.Connect wall 6 to be hidden in cover body 2, U.S. of whole printed circuit board (PCB) can be promoted
Sight degree.In a practical situation, connect in whether wall 6 is hidden in cover body 2 and make a decision according to reality, this
This is not specifically limited by embodiment.
And, it is notable that in the present embodiment, connect wall 6 and pass through with printed circuit board (PCB) 1
Locking member realizes removably connecting, and owing to the kind of locking member is the most, alternative scope is relatively wide,
The concrete kind of locking member is not limited by present embodiment, and in the present embodiment, locking member is selected
Screw realizes connecting being locked between wall 6 and printed circuit board (PCB) 1.Specifically, fill in reality
Timing, can be provided with screw at printed circuit board (PCB) 1 with being connected on wall 6 in advance, connects the screwhole position of wall 6
Corresponding with the screwhole position on printed circuit board (PCB) 1, screw is screwed in screw, be pressed on its end
On the surface of printed circuit board (PCB) 1, i.e. connecting fixing between wall 6 and printed circuit board (PCB) 1.And right
When radome is dismantled, it is only necessary to screwed out from screw by screw, can realize connecting wall 6 and printing
The separation of circuit board, completes the dismounting to radome so that radome is easier to dismounting, is conducive to safeguarding
Repairing, radome can also be reused, and saves material, reduces cost.Need explanation, in this reality
Executing in mode, the quantity about locking member is not especially limited, and determines according to radome practical situation, as
Really radome is relatively big, and locking member quantity can optionally increase.
It addition, in the present embodiment, the inner surface of cover body 2 is also covered with heat dissipation film (not indicating in figure),
Heat dissipation film is the thin film of one layer of heat conduction and heat radiation the thinnest, and circuit module, through working long hours, can cause temperature
Degree raises so that the equipment speed of service slows down, and the heat that heat dissipation film absorbing circuit module produces is also heat
Uniformly dispersing is gone out, and improves the heat dispersion of printed circuit board (PCB).
Further, the Mobile terminal main board structure of present embodiment also comprises the elasticity covering on radome absolutely
Edge layer.Elastic insulating layer can select foam or wheat to draw, using foam as elastic insulating layer as a example by carry out
Illustrating, foam covers on radome, and foam has certain elastic and lighter in weight, and fore shell is pressed in bubble face
On, foam plays pressuring action.
Second embodiment of the present utility model relates to a kind of Mobile terminal main board structure, as in figure 2 it is shown,
Roughly the same with the first embodiment, the second embodiment has done one on the basis of the first embodiment

Constitute the sinking portion 7 for propping up printed circuit board (PCB) 1.Sinking portion 7 and the printed circuit board (PCB) 1 of roof 4
Connect by locking member is fixing.
Specifically, the multiple circuit modules on printed circuit board (PCB) 1 are covered by radome, radome surrounding
Connection wall 6 fastened with printed circuit board (PCB) 1 by locking member, whole radome area comparatively speaking relatively greatly,
There is downwards depression after being under pressure in the middle part of radome, to cover body 2 circuit module below
Cause extruding.
Based on this, there is the direction being partially toward printed circuit board (PCB) 1 by middle position at cover body 2 roof 4
Bending forms a sinking portion 7, and sinking portion 7 props up printed circuit board (PCB) 1, the printing residing for sinking portion 7
Circuit board 1 is clear area, is i.e. not provided with circuit module；Sinking portion 7 and printed circuit board (PCB) 1 are by locking
Part is fixing to be connected, and the selection of locking member, with the first embodiment, the most just repeats no more.Sinking portion 7 with
The one side of printed circuit board (PCB) 1 contact is parallel with printed circuit board (PCB) 1, and radome is tight with printed circuit board (PCB) 1
Gu time, parallel contact surface is easy to fit to greatest extent, beneficially sinking portion 7 and printed circuit board (PCB) 1
Fixing.Wherein, sinking portion 7 is moderate with the size of printed circuit board (PCB) 1 contact surface, to select
Locking member make reference, area is preferably slightly larger than locking member cross section, it is simple to assembling.The quantity in sinking portion 7 with
Position is not fixed, and present embodiment is not specifically limited, and makes a decision with practical situation.
Shielding case structure with sinking portion 7 is simple, and dismounting is convenient, improves radome integrated support strong
Degree, and the aesthetics of the design lifting complete machine of integration, and there is practical value widely, be conducive to
Promote the use of.
It will be understood by those skilled in the art that above detailed description of the invention, to this reality
Further described with novel purpose, technical scheme and beneficial effect, it should be understood that
It is to these are only detailed description of the invention of the present utility model, is not used to limit this utility model
Protection domain, all within spirit and scope of the present utility model, any amendment of being made,
Equivalent, improvement etc., should be included in protection domain of the present utility model.
