Technical Field

The utility model relates to a PCB board technical field, in particular to shielding structure of PCB board.

Background

At present, most of the existing PCB shielding structures are welded on a PCB, or parts of mounting structures are welded on the PCB, so that the PCB shielding structures are difficult to disassemble, or electronic components on the PCB are easy to damage, and complicated procedures are increased.

SUMMERY OF THE UTILITY MODEL

In view of the above, the main objective of the present invention is to provide a shielding structure of a PCB board, which is convenient to disassemble and simplifies the installation structure.

In order to achieve the above object, the utility model provides a shielding structure of PCB board, include: PCB board, shield cover and connecting piece, shield cover detachably sets up on the PCB board, the shield cover has the open-ended box body for one side, be provided with a plurality of spliced poles on the shield cover, be provided with the external screw thread on the spliced pole, seted up on the PCB board with the corresponding through-hole of spliced pole, the connecting piece includes spacing piece and sets up perpendicularly the connection hollow tube at spacing piece middle part, the inner wall of connecting the hollow tube seted up with the internal thread of external screw thread adaptation, it establishes to connect the hollow tube insert in the through-hole, spacing piece butt is in the surface of PCB board.

Preferably, the shielding case is provided with a plurality of heat dissipation holes.

Preferably, the shielding case is provided with two reinforcing ribs.

Preferably, the connecting column and the shielding case are integrally arranged.

Preferably, the length of the connecting hollow tube is equal to the thickness of the PCB panel.

Preferably, the length of the connection post is less than the thickness of the PCB board.

Compared with the prior art, the technical scheme of the utility model adopts the connecting piece to be inserted into the through hole to be connected with the connecting column thread of the shielding cover, so as to fix the shielding cover on the PCB instead of being welded or clamped at the periphery of the PCB, thus simplifying the structure, facilitating the disassembly and being not easy to damage other elements; meanwhile, the connecting piece and the connecting column are made of certain heat conducting materials, so that heat on the PCB can be further transferred to the shielding cover with the larger heat dissipation area to dissipate heat.
