Description
Technical field
The utility model relates to a kind of coupling assembling and portable terminal thereof of screening cover.
Background technology
As shown in Figure 1, in the prior art, shield bracket 10 need be used with screening cover 20 usually, shield bracket 10 and screening cover 20 cooperates in the prior art, be by punching, the elastic piece structure of band salient point is set at the side of screening cover 20 at shield bracket 10 sides.Shield bracket 10 adopts SMT (Surface Mounted Technology, surface mounting technology) to be welded on PCB (Printed Circuit Board, the printed circuit board (PCB)) plate 30, and then by hand screening cover 20 is fastened on the shield bracket 10.
Shortcoming with shield bracket 10 fixed masks lid 20 is: when shield bracket 10 adopts SMT to be welded on the pcb board 30, can scrap owing to the bad pcb board that causes of SMT processing procedure; After assembling finished, the existence of shield bracket 10 had taken too much height space, causes the screening cover integral thickness excessive, thereby has increased the product integral thickness; And when the maintenance electronic component, at first need to dismantle screening cover 20, under 10 pairs of unencumbered situations of electronic component of shield bracket, just can keep in repair then, but because the restriction in space, shield bracket 10 all can be to covering electronic component formation obstruction in its lower section and being difficult to keep in repair, if destroy shield bracket 10, be easy to cause the damage of electronic component again.
The utility model content
The coupling assembling of a kind of screening cover that the utility model provides has solved because the existence of shield bracket causes the screening cover integral thickness excessive, and when the electronic component to its covering keeps in repair and the technical problem of inconvenience.
The utility model provides a kind of coupling assembling of screening cover, comprising: pcb board; First fixture, described first fixture is fixedly installed on the described pcb board; Second fixture; Screening cover, described screening cover is positioned at the top of described first fixture, and described screening cover is provided with fixing hole, and described second fixture passes fixing hole and matches with described first fixture.
Further, described first fixture is a nut, and described second fixture is a screw.
Further, described first fixture and second fixture are respectively equipped with at least one.
Further, described first fixture and second fixture are respectively equipped with at least 3.
Further, described screening cover comprises the shielding capping, covers side to the first screening cover side of pcb board direction bending formation and the secondary shielding of continuation bending formation, and described fixing hole is located on the secondary shielding lid side.
Further, described secondary shielding lid side is parallel to the shielding capping.
Further, the first screening cover side is perpendicular to shielding capping and secondary shielding lid side.
The utility model also provides a kind of portable terminal, comprises the coupling assembling of above any described screening cover.
The coupling assembling of a kind of screening cover that the utility model provides matches with second fixture that wore screening cover by first fixture that is fixed on the pcb board, screening cover is fixed on the pcb board easy assembly and disassembly; Cancelled shield bracket of the prior art, saved the use of operation and parts, reduced the integral thickness of screening cover, avoided because the maintenance needs are dismantled shield bracket and electronic component brought the risk of damage.

Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 2 to Figure 3, the utility model provides a kind of coupling assembling of screening cover, comprising:
Pcb board 100;
First fixture 210, described first fixture 210 is fixedly installed on the described pcb board 100;
Second fixture 220;
Screening cover 300, described screening cover 300 is positioned at the top of described first fixture 210, and described screening cover 300 is provided with fixing hole 310, and described second fixture 220 passes fixing hole 310 and matches with described first fixture 210.
Concrete, described PCB is Printed Circuit Board, is printed circuit board (PCB).
Concrete, described first fixture 210 is a nut, described nut is fixed on the pcb board 100 by scolding tin; Described second fixture 220 is a screw.Described first fixture 210 and second fixture 220 are respectively equipped with at least one, optimum, be 3, because such stationarity can be best.The utility model embodiment realizes carrying out ground connection with the ground wire of pcb board 100 by first fixture 210 that can conduct electricity and second fixture 220, and is optimum, matches by screw and nut and realizes ground wire grounded with pcb board 100.
Concrete, described screening cover 300 comprises shielding capping 320, covers side 340 to the first screening cover side 330 of pcb board direction bending formation and the secondary shielding of continuation bending formation, the first screening cover side 330 outwards continues bending to the pcb board direction and forms secondary shielding lid side 340, described fixing hole 310 is located on the secondary shielding lid side 340, can not increase the thickness of screening cover like this, not increase product thickness.Described secondary shielding lid side 340 is parallel to shielding capping 320, can guarantee the installation stability of screening cover 300 like this, optimum, the first screening cover side 330 can better guarantee the stability of screening cover 300 like this perpendicular to shielding capping 320 and secondary shielding lid side 340.
The utility model provides a kind of coupling assembling of screening cover, matches with second fixture that wore screening cover by first fixture that is fixed on the pcb board, screening cover is fixed on the pcb board easy assembly and disassembly; Cancelled shield bracket of the prior art, saved the use of operation and parts, saved the thickness that combines between the thickness of shield bracket and shield bracket and the screening cover, thereby reduced the integral thickness of screening cover, avoided because the maintenance needs are dismantled shield bracket and electronic component brought the risk of damage.
