[0002] A connector is an electromechanical component used to connect two or more electronic devices, circuits, or components to realize the transmission of electrical signals, power, or data. It generally consists of a male and a female terminal. The male terminal has insertable pins or tabs, and the female terminal has corresponding holes or slots. Conductivity is achieved through the mating of these two terminals. Connectors are used to connect power generation equipment, transmission lines, substation equipment, and power-consuming equipment to realize the transmission and distribution of power and ensure the stable operation of the power system. However, existing technologies have the following shortcomings in their use:

The locking effect between the plug connector and the socket connector is poor, which will affect the normal use of subsequent electronic products.
[0004] Therefore, there is an urgent need for a connector for a secondary locking mechanism to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to address the problem that, when a plug connector is inserted into a socket connector, it may detach from the socket connector if subjected to external force during use, resulting in poor locking between the plug connector and the socket connector and affecting the normal use of subsequent electronic products.

[0028] Example:
[0029] like Figure 1-5As shown, the connector for the secondary locking mechanism proposed in this embodiment includes a plug connector 1 and a socket connector 2 that mates with the plug connector 1. A rotating ring 3 is provided on the outer side of the socket connector 2, and the rotating ring 3 is rotatably sleeved on the socket connector 2. Two symmetrically distributed cylindrical inserts 4 are fixedly connected to one end face of the rotating ring 3. A positioning slot 5 is formed on one side surface of the cylindrical insert 4. A first fixing ring 6 is fixedly sleeved on the plug connector 1. The first fixing ring 6 has an annular guide groove 7 and two hole slots 8, which are symmetrically distributed about the central axis of the first fixing ring 6. The slot 8 is connected to the annular guide groove 7. The plug connector 1 is fixedly fitted with a second fixing ring 9. The annular guide groove 7 and the slot 8 are both adapted to the cylindrical plug 4. The plug connector 1 is movably fitted with a connecting ring 10. The connecting ring 10 is in contact with the first fixing ring 6. Several springs 11 are fixedly connected between the connecting ring 10 and the second fixing ring 9. Two symmetrically distributed positioning pins 12 are fixedly connected to the side surface of the connecting ring 10 away from the springs 11. The several springs 11 are arranged at equal angles around the connecting ring 10. Two through holes 13 are opened on one side surface of the first fixing ring 6.
[0030] Align the two slots 8 with the two cylindrical inserts 4, and insert the plug connector 1 into the socket connector 2, allowing the two cylindrical inserts 4 to enter the annular guide groove 7 through the two slots 8. Pull the connecting ring 10 towards the second fixing ring 9, causing the spring 11 to compress and deform. The two positioning pins 12 move synchronously with the connecting ring 10. After the two positioning pins 12 disengage from the two through holes 13, rotate the rotating ring 3, causing the two cylindrical inserts 4 to move within the annular guide groove 7. Through the engagement of the two positioning pins 12 with the first fixing ring 6, the plug connector 1 and the socket are connected. The primary locking of connector 2 occurs when the two cylindrical inserts 4 correspond to the two through holes 13 respectively. The connecting ring 10 is then released, and the elastic force of multiple springs 11 drives the connecting ring 10 to move and reset, so that the connecting ring 10 fits against the first fixed ring 6. The two positioning pins 12 are inserted into the two positioning slots 5 through the two through holes 13 respectively, thereby positioning the rotating ring 3 and preventing the rotating ring 3 from rotating. This achieves secondary locking of plug connector 1 and socket connector 2, ensuring the stability of the connection between plug connector 1 and socket connector 2, which is beneficial for practical use and is simple and convenient to operate.
[0031] like Figure 1 , Figure 2 and Figure 5 As shown, the two positioning pins 12 are respectively located in the two through holes 13. The diameter of the through holes 13 is the same as the diameter of the positioning slot 5. When the two positioning pins 12 are inserted into the two positioning slots 5 through the two through holes 13, the rotating ring 3 can be positioned to prevent the rotating ring 3 from rotating and to achieve locking between the plug connector 1 and the socket connector 2.
