[0022] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] like Figures 1 to 5 As shown, the present invention provides a connector with high connection stability, including a socket 1 and a plug 2 that cooperates with the socket 1. A sealing ring 3 is provided on one side of the socket 1, and a sealing block 4 is provided on one end of the plug 2. A sliding groove 5 is provided on one side of the sealing ring 3. A secondary locking mechanism 6 is provided on the inner side of the sliding groove 5. The secondary locking mechanism 6 includes a connecting rod 601 fixedly installed on the inner wall of the sliding groove 5. A stop block 602 is sleeved on the outer side of the connecting rod 601. A spring 603 is provided on the outer side of the connecting rod 601. An insertion rod 604 is provided at one end of the stop block 602. A push rod 605 is provided on the outer side of the insertion rod 604.

[0024] refer to Figures 1 to 5 The push rod 605 is located inside the slide groove 5. A through hole 7 is provided on one side of the slide groove 5, and the through hole 7 extends through to the inner wall of the sealing ring 3. The plug rod 604 is movably installed in the inner cavity of the through hole 7. A locking hole 10 is provided on one side of the sealing block 4. One end of the plug rod 604 is inserted into the inner cavity of the locking hole 10. An elastic handle 11 is provided in the middle of the top of the plug 2. A locking block 12 is provided on one side of the top of the elastic handle 11. A protrusion 13 is provided on the top of the inner cavity of the socket 1, and the protrusion 13 and the locking block 12 are locked together. A fixing block 9 is provided at one end of the socket 1. A fixing hole 14 is provided on the surface of the fixing block 9.

[0025] The above solution employs the following: the sealing ring 3 prevents impurities and moisture from entering the connector, improving the sealing performance; the sealing block 4 cooperates with the sealing ring 3 to create a seal during connection; the slide groove 5 guides and fixes the secondary locking mechanism 6 to improve connection stability; the through hole 7 on one side of the slide groove 5 allows for the movable installation of the insertion rod 604; the snap hole 10 receives the insertion rod 604, forming a secondary lock; and the stop block 602 limits the movement range of the insertion rod 604 and simultaneously facilitates the spring 603 to... The elastic force acts on the plug rod 604, and the spring 603 provides elastic support, ensuring that the plug rod 604 has a certain fastening force. The plug rod 604 locks the connection between the plug 2 and the socket 1. The push rod 605 drives the stop block 602 to compress the spring 603, causing the plug rod 604 to disengage from the inner cavity of the locking hole 10, thereby releasing the lock of the secondary locking mechanism 6. The elastic handle 11 controls the insertion and removal of the plug 2. By engaging the locking block 12 and the protrusion 13, the connection between the plug 2 and the socket 1 is enhanced.

[0026] refer to Figures 2 to 4 The inner wall of the sealing ring 3 and the outer side of the sealing block 4 are both provided with sealing mechanisms 8. The sealing mechanism 8 includes a groove 801 opened in the inner wall of the sealing ring 3, a sealing strip 802 is engaged in the inner side of the groove 801, and an installation groove 803 is opened in the outer side of the sealing block 4, and a sealing ring 804 is sleeved in the inner side of the installation groove 803.

[0027] The above solution allows for the fixing and limiting of the sealing strip 802 via the slot 801, and the fixing and limiting of the sealing ring 804 via the mounting groove 803. The combination of the sealing strip 802 and the sealing ring 804 prevents moisture, dust, and other impurities from entering the connector, protecting the stability and reliability of the internal circuitry and effectively preventing contamination or corrosion of the electrical contact parts.

[0028] Working principle:

[0029] During use, the user inserts the plug 2 into the socket 1. The sealing block 4 contacts the sealing ring 3 and forms a preliminary seal. As the plug 2 is inserted into the socket 1, the locking block 12 and the protrusion 13 engage with each other, completing the initial locking. At the same time, the plug rod 604 is pushed by the sealing block 4, and the stop block 602 compresses the spring 603. When the plug rod 604 coincides with the locking hole 10, the pressure on the spring 603 disappears. Under the elastic action of the spring 603, the plug rod 604 is pushed into the locking hole 10, achieving secondary locking and increasing the continuity. To ensure the stability of the connection, a sealing barrier is formed at the connection between the sealing block 4 and the sealing ring 3 by the sealing strip 802 and the sealing ring 804, preventing external liquids, dust and other impurities from entering the connector and keeping the connector clean and safe. When the plug 2 is pulled out, the user can use the elastic handle 11 to separate the locking block 12 from the protrusion 13, and then push the push rod 605 to drive the stop block 602 to compress the spring 603, thereby causing the plug rod 604 to disengage from the inner cavity of the locking hole 10, thereby unlocking the secondary lock of the plug 2 and the socket 1.

[0030] In summary, this connector with high connection stability, through the secondary locking mechanism 6, can additionally lock the connection after the plug 2 is fully inserted into the socket 1, preventing accidental detachment or loosening. This ensures the connector maintains stability under any working conditions and effectively prevents the connector from loosening or breaking due to external factors such as vibration and bumps, avoiding potential malfunctions or safety risks. Through the sealing mechanism 8, moisture, dust, and dirt can be effectively prevented from entering the connector, protecting the electronic components inside the connector from damage, improving the reliability and stability of the connector, and effectively isolating it from contact with air and other chemicals, preventing electronic components from being corroded or oxidized, and extending the service life of the connector.
