Description

Technical Field

[0001] The invention relates to the field of board card installation, and in particular to a board card clamping structure which is convenient for installation. Background Art

[0002] Board is a relatively abstract name, which is a kind of printed circuit board (PCB board for short). Generally, PCB modules that are combined with PC and can complete certain communication, data exchange, and other specific functions are collectively referred to as boards. For example, data acquisition card, motion control card, video acquisition card. They can all be called boards. The main function of the board is to realize the function of the gateway, helping the slave stations under some customers' industrial computers to perform a series of protocol conversions, so that users can use a unified standard in various real-time Ethernet fieldbus systems based on PC automation. Of course, the complete protocol stack is implemented in the board. In general, the emergence of the board has greatly helped customers get rid of user PC applications. When the board acts as a master station, it can still carry a standard number of slave stations in parallel. The emergence of the board has greatly helped customers get rid of user PC applications. Board suppliers generally provide some demo programs for customers to develop and use.

[0003] When the board is in use, a snap-fit ​​structure is generally required to install the board. In the authorized Chinese utility model patent "Announcement No.: CN212786322U, Name: A snap-fit ​​mounted circuit board and a snap-fit ​​seat matching the circuit board", it is easy to align by installing hollow positioning columns on the four corners of the board body of the traditional circuit board, and matching with the corresponding snap-fit ​​seats. During operation, it is only necessary to press the horizontal push rod to move the horizontal snap-fit ​​rod inward, and the hollow positioning column can be embedded in the snap-fit ​​seat. The operation is simple. When releasing the operation, it is only necessary to press the horizontal push rod again and pull up the board body. However, in the above application, only boards of the same model can be snapped together. When the size of the board or the type of components on the card is different, the application scope of the snap-fit ​​structure is small, and the embedded connection between the positioning column and the snap-fit ​​seat is prone to loosening due to external forces such as wear after long-term use, affecting the stability of the board installation.
