Description
Technical Field
The invention relates to the field of mobile terminal devices, in particular to a shielding device for a mobile terminal.
Background
Mobile devices (e.g., tablet computers, notebook computers, mobile phones) generally include a circuit board, a shield case, and a metal casing; the following problems exist with current shielding cases for mobile devices:
firstly, the height of the shielding cover cannot be adjusted, and when the shielding cover is installed, the shielding covers with different sizes are designed according to different circuit boards, so that the workload is large, and the cost is high;
secondly, the height of the shielding cover can not be adjusted, and when the shielding cover is installed, the requirements can not be met when fine adjustment is needed according to different installation sites.
Disclosure of Invention
The invention aims to provide a shielding device for a mobile terminal, which can realize high fine adjustment.
The technical scheme of the invention is as follows:
a shielding device for a mobile terminal comprises a circuit board and a plurality of components arranged on the circuit board; the circuit board is also provided with a shielding cover; the shielding cover comprises a top cover and a bottom frame, and a groove matched with the bottom frame is formed in the bottom side edge of the top cover.
The shape of the bottom frame is matched with that of the circuit board.
At least two adjusting bolts are uniformly distributed on the top side of the top cover and penetrate through screw holes on the top side; the screw holes are communicated with the corresponding grooves.
And a shell is covered on the circuit board outside the shielding cover.
And a plurality of reinforcing ribs are uniformly distributed on the inner wall surface of the shell.
At least two guide posts are uniformly distributed on the top side of the bottom frame, at least two guide holes are uniformly distributed on the top side of the top cover, and the guide holes correspond to the guide posts one to one.
The invention has the beneficial effects that: the shielding cover is divided into the top cover and the bottom frame, so that the height of the components in the circuit board can be adjusted, and the installation is more convenient; the bottom frame can be inserted into the groove, so that the height of the shielding cover can be adjusted;
firstly, aligning the guide hole with the guide post, and then clamping the bottom frame into the groove of the top cover; when the shielding cover needs to be heightened, an adjusting bolt with a longer length is screwed in; when the shielding cover needs to be lowered, only the adjusting bolt with shorter length needs to be screwed in.
Drawings
The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.
Wherein: FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of a guide post structure according to the present invention;
in the attached drawing, 1 is a circuit board, 2 is a component, 3 is a shielding case, 4 is a top cover, 5 is a bottom frame, 6 is a shell, 7 is an adjusting bolt, 8 is a reinforcing rib, 9 is a guide post and 10 is a guide hole.
Detailed Description
Referring to fig. 1, a shielding device for a mobile terminal includes a circuit board 1, and a plurality of components 2 disposed on the circuit board; the circuit board is also provided with a shielding cover 3; the shielding cover comprises a top cover 4 and a bottom frame 5, and a groove matched with the bottom frame is formed in the bottom side edge of the top cover. The shielding cover is divided into the top cover and the bottom frame, so that the height of the components in the circuit board can be adjusted, and the installation is more convenient; the bottom frame can be inserted into the groove, so that the height of the shielding cover can be adjusted.
The shape of the bottom frame is matched with that of the circuit board. The shielding cover has better covering effect.
At least two adjusting bolts 7 are uniformly distributed on the top side of the top cover and penetrate through screw holes on the top side. The screw holes are communicated with the corresponding grooves. Adjusting bolt is first to be located the overhead guard outside, and the other end supports underframe top side, when screwing in adjusting bolt like this, will make the overhead guard rebound to adjust the height of overhead guard and circuit board.
And a shell 6 is covered on the circuit board outside the shielding cover. The shielding case and the internal components can be protected by arranging the shell.
And a plurality of reinforcing ribs 8 are uniformly distributed on the inner wall surface of the shell. The strength of the shell is enhanced through the reinforcing ribs, and the protection effect is improved.
At least two guide posts 9 are uniformly distributed on the top side of the bottom frame, at least two guide holes 10 are uniformly distributed on the top side of the top cover, and the guide holes correspond to the guide posts one to one. The cooperation of guide post with the guiding hole plays better guide effect when screwing adjusting bolt and makes things convenient for the removal of overhead guard on the one hand, and on the other hand can play a predetermined position effect, easy to assemble when the installation overhead guard.
The following working principle is described:
firstly, aligning the guide hole with the guide post, and then clamping the bottom frame into the groove of the top cover; when the shielding cover needs to be heightened, an adjusting bolt with a longer length is screwed in; when the shielding cover needs to be lowered, only the adjusting bolt with shorter length needs to be screwed in.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications and equivalent variations of the above embodiment according to the present invention are within the scope of the present invention.
