Technical field
The invention belongs to electronic device field, more particularly, to a kind of shielding box based on radio frequency connector.
Background technology
In some specific work environments, because the application of radio-frequency apparatus by two printed boards, it is necessary to realize circuit work(
Can, if two printed boards are directly connected with line, (1) can be caused because circuit not prison welding is solid and does not have the originals such as outer protection
Cause, rupture of line is caused, even resulting in can not normal work；(2) two printed boards can not be fixed in cabinet；(3) it is every
Because working frequency is different between bar radio frequency link, exist and interfere, working effect can be influenceed, or even can not normal work.
(4) bare board is also easily by extraneous complicated electromagnetic environment interference etc..
The content of the invention
In view of this, the present invention is directed to propose a kind of screen based on radio frequency connector that can connect two printed circuit board (PCB)s
Box is covered, to solve the interference problem between two printed circuit board (PCB)s and fixation.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：
A kind of shielding box based on radio frequency connector, including：Box body and lid, described box body inner side are provided with the first print
Circuit board PCB processed, the outside one side of box body are provided with the second printing board PCB, the first described printing board PCB and the
Two printed circuit boards are connected by radio frequency connector SMP；Lid, described lid lid are connected on box body.
Further, described tray interior bottom surface is provided with multiple dividing walls, and cavity, cavity are formed between multiple dividing walls
The radio frequency link of corresponding first printing board PCB；Multiple dividing walls, multiple isolation are again provided with the outside of described box bottom
Cavity, the radio frequency link of corresponding second printing board PCB of cavity are formed between wall.
Further, described radio frequency connector SMP is at least 6.
Further, the second described printed circuit board screw connection is in the bottom surface of box body.
Further, described box body is metallic shield box body.
Further, the material of described metallic shield box body is aluminium.
Relative to prior art, a kind of shielding box based on radio frequency connector of the present invention has the advantage that：
(1) present invention not only improves dismounting, is beneficial to debugging again, and two printing board PCBs both can be debugged independently, simultaneously
Operating efficiency is improved, while uses cavity isolation not interfered between also ensuring every radio frequency link, shields electromagnetism spoke
Penetrate.Overall box body design, can shield the electromagnetic interference with other modules in cabinet.
(2) design of two-sided shielding box, overall weight is both reduced, and can saves material, while also eliminates two screens
Cover the problem that box is connected.
