2. The locking mechanical principles of different locking mechanisms are different, the locking force is different, and the reliability is also different. Therefore, it brings uncertainty to customers and reduces reliability;

3. The connection force is generated by manual pulling, which increases the labor intensity of the operator and increases the risk of misoperation;

4. All the above-mentioned locking mechanisms are pivotally connected to the plug connector or socket connector and cannot be separated independently. Therefore, for customers, maintenance is inconvenient. In some cases, the only option is to scrap the entire product. Instead of just scrapping the locking mechanism, keep the plug and socket connectors working; and

5. In terms of the function of ensuring the IP65 waterproof level, the sealing is very simple and the reliability is poor.
