Detailed Implementation

[0020] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Please refer to Figure 1This utility model provides a manual plugging and unplugging device 100, including a carrier 10, a connecting rod structure 20, a guide rail 30 and a guide frame 40. The carrier 10 is used to place the test interface 200, and a connecting plate 11 is provided on the carrier 10.

[0022] Please refer to Figure 2 and Figure 3 The linkage structure 20 includes a fixed plate 21, a first rotating plate 22 and a second rotating plate 23. The first rotating plate 22 and the fixed plate 21 are rotatably connected. The first rotating plate 22 and the second rotating plate 23 are rotatably connected. The second rotating plate 23 and the connecting plate 11 are rotatably connected. The first rotating plate 22 is provided with a handle 221.

[0023] Specifically, in this embodiment, there are two of each of the fixed plate 21, the first rotating plate 22, and the second rotating plate 23, with a handle 221 located between the two first rotating plates 22. During insertion and removal, by pulling the handle 221, the two first rotating plates 22 are rotated, which in turn causes the second rotating plate 23 to move the connecting plate 11 and the carrier 10, thereby enabling the insertion and removal of the test interface 200.

[0024] Please refer to Figure 1 and Figure 2 The carrier 10 is slidably mounted on the guide rail 30. The guide frame 40 is provided with a guide groove 41 corresponding to the guide rail 30, and the first rotating plate 22 passes through the guide groove 41 and swings within the guide groove 41.

[0025] The guide groove 41 and guide rail 30 on the guide frame 40 guide and limit the linkage structure 20 and the carrier frame 10 respectively, so that when the connection structure in the linkage structure 20 is loose, the test interface 200 is not easy to deviate during insertion and removal, thereby improving the insertion and removal accuracy.

[0026] Meanwhile, the guide groove 41 restricts the rotation range of the first rotating plate 22, so that the first rotating plate 22 is less likely to rotate too much and cause the test interface 200 to be over-plugged, resulting in damage to the test interface 200.

[0027] Please refer to Figure 4 and Figure 5 The carrier 10 is equipped with a first connecting block 12 corresponding to the test interface 200. The test interface 200 is connected to a second connecting block 201. The first connecting block 12 is equipped with a connecting bolt 121 and a spring 122. The spring 122 is sleeved on the connecting bolt 121. The second connecting block 201 is equipped with a connecting hole 2011 for the second connecting bolt 121. When the test interface 200 is inserted, the connecting bolt 121 passes into the connecting hole 2011 and the second connecting block 201 presses against the spring 122. Specifically, the second connecting block 201 is located on the end of the test interface 200 that passes through the first connecting block 12. The first connecting block 12 is equipped with a through groove (not labeled in the figure) for the test interface 200 to pass through.

[0028] By setting up connecting block 12, connecting bolt 121 and spring 122, when the linkage structure 20 drives the carrier 10 to insert the test interface 200, the interface on the circuit board generates a reverse force after being subjected to the insertion force of the test interface 200. This, in turn, causes connecting block 201 to apply pressure to spring 122. The elastic force generated by the compression of spring 122 cancels out the insertion force, causing the test interface 200 to float relative to the interface on the circuit board, thereby reducing the possibility of damage to the test interface 200 due to excessive insertion force.

[0029] Please refer to Figure 1 The manual insertion and removal device 100 also includes a rotary pressing cylinder 50. The output end of the rotary pressing cylinder 50 is provided with a pressing block 51. The rotary pressing cylinder 50 is used to drive the pressing block 51 to move to press the handle 221 onto the guide frame 40.

[0030] By rotating the downward pressure cylinder 50, the handle 221 and the connecting rod structure 20 are fixed after the insertion is completed, thereby preventing the connecting rod structure 20 from moving due to vibration and causing the test interface 200 to detach after insertion, thus improving the stability of insertion and removal.

[0031] Specifically, the pressure block 51 is an arc-shaped block that fits against the outer periphery of the handle 221. By setting the arc-shaped block, the pressure block 51 and the handle 221 fit more closely, which makes it easier for the pressure block 51 to fix the handle 221 and improves the stability of the pressure block 51 in fixing the handle 221.

[0032] Please refer to Figure 1 The guide frame 40 is provided with a positioning block 42, and the positioning block 42 is provided with a positioning groove 421. When the rotary pressing cylinder 50 drives the pressing block 51 to press the handle 221 onto the guide frame 40, the pressing block 51 is locked in the positioning groove 421. The positioning block 42 facilitates the positioning of the pressing block 51 driven by the rotary pressing cylinder 50 to the position corresponding to the handle 221 after insertion and removal, thereby facilitating the fixing of the handle 221 by the pressing block 51.
