Through this setting, when connecting the socket module 1 and the plug module 2, by approaching the two and utilizing the chamfered design of the mating header 22 and the mating slot 113 and the gap between the base column 141 and the connecting hole 116, the mating slot 113 is allowed to float slightly when back-inserted, which facilitates the cooperation between the guide column 115 and the guide hole 28, making it easier to insert the mating header 22 into the mating slot 113. During the process, the pin head 131 of the pin assembly 13 passes through the through hole 24 and is inserted into the split slot plug hole 26 of the plug module 2 to complete the connection. The design of the split slot plug hole 26 ensures a soft plugging and unplugging force, avoids connection difficulties or damage, improves durability and reliability, reduces mechanical stress, extends service life, and enhances equipment stability and user experience.

[0031] Workflow: The operation of the inter-board connector is as follows. Note: the socket module 1 is installed on one side of the circuit board through the fastening bolt 125, and the plug module 2 is installed on the other side of the circuit board through the fastening bolt 29; when the connector needs to be adjusted according to the design requirements of the board spacing, the adjustment operation is: first, the track plate 154, the rotating shaft 153, the connecting piece 152 and the pair of rolling rods 151 are driven to rotate accordingly by rotating the rotating block 156. In this process, the rotation of the track plate 154 will drive the upper and lower elastic card frames 155 to rotate, and the elastic card frames 155 The rotation will apply pressure to the connecting rod 146 located inside it. Since the elastic card frame 155 itself has a certain elasticity, this pressure will cause its card channel to deform, so that the connecting rod 146 can be displaced in the card channel of the elastic card frame 155. This pressure will also cause the connecting rods 146 on the front and rear sides to move backwards. The backward movement of the connecting rod 146 will further pull the opposite ends of the upper and lower rotating arms 145 to displace and rotate, thereby prompting the upper and lower connecting seats 143 to move toward each other. Through this arrangement, the contraction of the foldable middle joint 14 can be achieved, thereby Adjust the distance between the upper seat 11 and the lower seat 12; when the required size is adjusted, stop rotating the rotating block 156. At this time, the card paths of each elastic card frame 155 will return to their original positions due to the elastic effect, and reposition the connecting rod 146. In this way, the adjusted foldable middle joint 14 can be fixed, and the positions of the upper seat 11 and the lower seat 12 can also be accurately positioned. As the distance between the upper seat 11 and the lower seat 12 is reduced, the wire 132 located therebetween will gradually change from its original straight state to a relaxed state. During this adjustment process, The pair of winding rods 151 rotating together with the track plate 154 will synchronously reel in the gradually loosened wires 132 to prevent the wires 132 of each pin assembly 13 from becoming too messy. Through the above operation, the size of the socket module 1 is adjusted, and the inter-board connector can be adaptively and quickly adjusted in size according to the design requirements of the board spacing. This solves the problem that the existing inter-board connector, whose structural dimensions are usually fixed, cannot adapt well to the design requirements of different board spacings, which limits the versatility and flexibility of the product.Connection operation: When it is necessary to connect the socket module 1 and the plug module 2, just move the two close to each other. The connection process first utilizes the chamfer design of the mating header 22 and the mating slot 113, as well as the appropriate gap between the mating base column 141 and the connecting hole 116, so that the mating slot 113 on the upper seat 11 can achieve a small floating displacement when back-inserted. This design is conducive to the subsequent mating guidance of the guide column 115 and the guide hole 28, so that the mating header 22 can be more easily inserted into the mating slot 113. During the insertion process, the pin heads 131 of each pin assembly 13 will pass through the corresponding through-hole 24 and smoothly insert into the split slot plug-in hole 26 of each plug module 2, thereby completing the socket module 1 and When disconnection is required, the special design of the split-slot plug hole 26 allows for gentle insertion and removal forces, ensuring a smooth connection process. This design avoids the problems of excessive insertion and removal forces, resulting in difficult connections or damage associated with traditional connectors, while also reducing potential damage to the connector and circuit board. Furthermore, this design improves connection reliability and durability by reducing mechanical stress caused by improper insertion and removal, thereby extending the life of the connector. This optimized connection method provides a more stable connection between the socket module 1 and the plug module 2, improving the overall reliability and user experience of the electronic device.
