An outer lock sleeve 102 is rotatably connected to the adapter housing 106, the outer lock sleeve 102 can be rotated by a small amount on the adapter housing 106, and a guide lock groove 102a for locking the connector 300 is provided on the outer wall of the outer lock sleeve 102. When the connector 300 is press-fitted with the adapter housing 106, the lock catches 302a of the connector 300 slide into the guide locking grooves 102a to urge the outer locking sleeve 102 to rotate in the locking direction.

When the guide locking groove 102a is locked with the connector 300, the second hook 105b is connected with the guide block 102b to limit the outer locking sleeve 102 to rotate in the unlocking direction to achieve self-locking. The present application adopts push-type plug connection, so that the adapter 100 and the connector 300 are connected in a plug-in manner, the space utilization rate is improved, and more adapters 100 are arranged in the same space range.

In some alternative embodiments: referring to fig. 5-7, embodiments of the present application provide a push-to-connect adapter, with the guide block 102b of the adapter 100 preferably having a right triangle configuration.

When the latch 302a of the connector 300 slides into the guide groove 102a1 to push the outer locking sleeve 102 to rotate toward the locking direction, the second hook 105b enters the latch channel 102g under the oblique guiding action of the guide block 102 b.

When the lock catch 302a of the connector 300 slides into the locking groove 102a2, the second hook 105b is connected with the guide block 102b, and at this time, after the second hook 105b enters the locking channel 102i, under the elastic force of the unlocking spring 104, the second hook 105b is positioned in the groove of the guide block 102b, so as to complete the automatic locking action of the connector 300 and the guide locking groove 102a.

When the latch 302a of the connector 300 slides into the trip groove 102a3, the second hook 105b trips the guide block 102b, and the connector 300 is unlocked from the outer locking sleeve 102. At this time, the second hook 105b is separated from the locking channel 102i and enters the releasing channel 102h, and the second hook 105b entering the releasing channel 102h drives the outer locking sleeve 102 to gradually rotate towards the unlocking direction on the adapter shell 106 under the elastic force of the unlocking spring 104 due to the fact that the second hook 105b is not connected with the guiding block 102b, so that the automatic unlocking action of the connector 300 and the guiding locking groove 102a is completed.

In some alternative embodiments: referring to fig. 1 to 4 and 8, the embodiment of the present application provides a push-in connection adapter, in which a shoulder surrounding the outer circumference of an adapter housing 106 is provided on the outer wall of an adapter housing 106 of the adapter 100, and a seal ring 103 is connected between an outer locking sleeve 102 and the shoulder.
