[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-5 A detachable locking module for a connector includes a backplane PCB1 and a current and signal contact spring 2 installed at the middle right side of the backplane PCB1. A daughter card PCB3 is installed on the right side of the current and signal contact spring 2. Guide blocks 4 are attached to the right side of the backplane PCB1 near the front and rear sides, and locking blocks 7 are attached to the right side of the guide blocks 4. The bottom of the locking blocks 7 is attached to the daughter card PCB3. The guide blocks 4 and locking blocks 7 can lock the backplane PCB1 and the daughter card PCB3, resulting in high stability.

[0024] Guide posts 5 are fixedly installed on the right side of the guide block 4 near the middle, and guide holes matching the guide posts 5 are opened on the locking block 7. The outer side of the guide posts 5 is inserted into the inner cavity of the adjacent guide holes, which guides the guide block 4 and the locking block 7 to the left and right when they are locked and inserted, which helps to better lock the back board PCB1 and the daughter card PCB3.

[0025] The guide block 4 is equipped with a foolproof design 6 on the right side near the top, which further improves the guiding function and makes the operation clear and convenient.

[0026] The left side of the locking block 7 near the top is provided with a foolproof groove for the plug-in of the foolproof design 6, which facilitates the further development of the work.

[0027] In this embodiment: When installing the backplate PCB1 and the daughter card PCB3, they can be fitted together. In addition, the guide block 4 and the locking block 7 will also fit together. When they fit together, the guide post 5 plays a guiding role, which helps to improve the efficiency of mating. The foolproof design 6 and the foolproof groove can further improve the guiding effect. At the same time, the operation is simple and does not require complicated steps, so as to achieve rapid mating.

[0028] Example 2

[0029] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1-5The guide block 4 has several threaded holes A at equal intervals, and the back plate PCB1 has threaded holes B corresponding to the middle threaded holes on the front and rear sides. The threaded holes B and the inner cavities of the adjacent threaded holes A are threaded through and screws A are installed.

[0030] The locking block 7 has screw holes on its left side near the top and bottom, and screws B are installed through the screw holes and adjacent threaded holes A.

[0031] Screw holes A are respectively opened at the bottom of locking block 7, and screw holes B corresponding to screw holes A are respectively opened on the front and rear sides of the sub-card end PCB3. Screws C are threaded through screw holes A and adjacent screw holes B.

[0032] In this embodiment: screw A serves to install the guide block 4 and the backplate PCB1, while screw B secures the locking block 7 and guide block 4 when they are in contact. Screw C facilitates the fixing of the locking block 7 and the sub-card PCB3. The use of screws A, B, and C reduces the possibility of gaps arising from vibration between the backplate PCB1, sub-card PCB3, guide block 4, and locking block 7, thus improving system stability. Furthermore, this locking mechanism using screws A, B, and C significantly enhances the stability between the connectors, allowing for unilateral removal from the sub-card PCB3. This ensures connection stability while facilitating installation and removal, separating the guide block 4, locking block 7, and connectors, and improving the flexibility of product arrangement.

[0033] Working Principle: During use, when installing the backplate PCB1 and daughter card PCB3, they are brought into a close-fitting configuration. This also causes the guide block 4 and locking block 7 to align. The guide post 5 guides the assembly during this process, improving mating efficiency. The foolproof design 6 and foolproof groove further enhance the guiding effect. Operation is simple, requiring no complicated steps, enabling rapid mating. Screw A secures the guide block 4 to the backplate PCB1, while screw B locks the locking block 7 and guide block 4 in place. The installation of screw C facilitates the fixation between locking block 7 and sub-card PCB3. The installation of screws A, B, and C reduces the possibility of gaps caused by vibration between backplate PCB1, sub-card PCB3, guide block 4, and locking block 7, thus improving system stability. In addition, this locking mechanism significantly enhances the stability between connectors. It allows for unilateral removal from sub-card PCB3, ensuring connection stability while facilitating installation and removal. It also separates guide block 4, locking block 7 from the connector, improving the flexibility of product arrangement.
