[0019] In this embodiment, when the first connector 20 and the second connector 30 are connected, the second connector 30 is aligned with the first connector 20, and then the second connector 30 is manually driven to move toward the first connector 20, so that the second clamping sleeve 32 extends into the inner cavity of the first clamping sleeve 22, driving the clamping rod 31 to contact the port of the first clamping sleeve 22, and then the second connector 30 rotates around the axis of the second clamping sleeve 32, driving the clamping rod 31 to enter the clamping spiral groove 23 and be restricted by the locking component 10, thereby completing the quick connection process; By using the first clamping sleeve 22 and the second clamping sleeve 32 in cooperation, the second connector 30 rotates so that the clamping rod 31 quickly enters the clamping spiral groove 23 and is restricted by the locking assembly 10, thereby achieving a quick connection and improving the connection efficiency. The locking assembly 10 ensures the stability and reliability of the connection, prevents accidental falling off during the connection process, and ensures good electrical performance. By directly driving the second connector 30 to move and rotate toward the first connector 20, the operation process is simple and easy to understand, convenient for users to use, and convenient for performing a quick connection process in a small environment; In summary, the present invention achieves fast, reliable and simple connection and disconnection while ensuring good electrical performance, and has good practicality and promotion value.

[0023] Specifically, a clamping sealing ring 35 is provided on the second clamping sleeve 32, and the clamping sealing ring 35 is arranged at the port of the second clamping sleeve 32. The clamping sealing ring 35 is adapted to the clamping cavity 28, and the second clamping sleeve 32 extends into the clamping cavity 28, so that the clamping sealing ring 35 is in close contact with the inner wall of the clamping cavity 28.

[0024] In this embodiment, when the second clamping sleeve 32 extends into the inner cavity of the first clamping sleeve 22, the second clamping sleeve 32 extends into the clamping cavity 28; When the second connector 30 is connected to the first connector 20 , the clamping seal ring 35 is in close contact with the inner wall of the clamping cavity 28 , completing the sealing process to improve the sealing performance throughout the day.

[0025] Specifically, a support ring groove 27 is formed on the sealing sleeve 26 , a support ring plate 40 is disposed in the support ring groove 27 , a support spring 41 is disposed between the support ring plate 40 and the support ring groove 27 , and the support ring plate 40 cooperates with the mounting tube 36 .

[0026] Specifically, a support contact ring 34 is provided on the mounting tube 36 , and the support contact ring 34 is arranged inside the second clamping sleeve 32 . The second clamping sleeve 32 extends into the clamping cavity 28 , so that the support contact ring 34 extends into the support ring groove 27 to squeeze the support spring 41 .

[0027] In this embodiment, when the second clamping sleeve 32 extends into the clamping cavity 28, the support contact ring 34 extends into the support ring groove 27 and contacts the support ring plate 40. When the second connector 30 is connected to the first connector 20, the support contact ring 34 squeezes the support spring 41 to further improve the sealing effect. Of course, when the locking assembly 10 does not lock the clamping rod 31 , the support spring 41 is reset, pushing the support contact ring 34 to move, thereby pushing the second connector 30 to move, so that the second connector 30 can be quickly separated from the first connector 20 .

[0028] Specifically, two sets of sliding grooves 24 are formed on the outer wall of the first clamping sleeve 22; The locking assembly 10 includes two groups of sliding plates 11, which are respectively slidably arranged in two groups of sliding grooves 24. The sliding plates 11 are provided with sliding inclined surfaces 14, and the clamping rods 31 are in contact with the sliding inclined surfaces 14, so that the sliding plates 11 are displaced toward the second connector 30 and contact-locked.

[0031] In this embodiment, when the clamping rod 31 is locked, the clamping rod 31 first contacts the sliding inclined surface 14. Since the clamping rod 31 rotates with the axis of the second connector 30, the clamping rod 31 moves along the path of the clamping spiral groove 23, and squeezes the sliding plate 11, so that the sliding plate 11 is lifted in the sliding groove 24, so that the locking spring 13 is in a stretched state. When the clamping rod 31 is no longer in contact with the sliding plate 11, the locking spring 13 is reset, driving the locking sleeve 12 and the sliding plate 11 to reset, and the sliding plate 11 is placed in the clamping spiral groove 23 to lock the clamping rod 31. Of course, when the second connecting head 30 needs to be detached from the first connecting head 20, the locking sleeve 12 is pushed to move toward the second connecting head 30 to release the restriction on the clamping rod 31. At the same time, the locking sleeve 12 and the sliding plate 11 contact the second connecting head 30 and push the second connecting head 30 to move, so that the second connecting head 30 can be quickly detached from the first connecting head 20.
