Description

Technical Field

[0001] The utility model relates to the field of PCB protection devices, in particular to a connection structure and a PCB protection cover. Background Art

[0002] With the development of science and technology, electronic products have been used more and more widely, and the demand for PCB boards has also increased. Before processing, large PCB boards need to be cut into small PCB boards of required shapes and sizes. These large PCB boards need to be stored or transported together before processing. In order to save space, PCB boards are usually stacked one by one, so that the PCB boards are in direct contact with each other. If there is shaking and vibration during transportation, the surface of the PCB board will be scratched. Therefore, it is particularly necessary to separate the PCB boards to prevent direct contact between the PCBs and to prevent vibration.

[0003] In the prior art, a protective cover is usually provided on the surface of the PCB board to prevent the surface from being scratched due to direct contact between the PCB boards, and a rubber pad is provided inside the protective cover to clamp and fix the protective plate.

[0004] However, the protective cover can only hold one PCB board, which is costly. In addition, there is a gap between the protective cover and the PCB board, which causes shaking during transportation. In addition, the surface of the protective cover is smooth, which can easily cause slippage during stacking and transportation, thereby damaging the PCB board. Utility Model Content
