[0031] Please refer to the attached Figure 1 and the attached Figure 2 , which shows a push-button self-sealing quick connector for a liquid cooling device, including a plug connector 20 and a socket 10. The socket 10 is characterized in that it includes a socket housing 11, a button housing 15, a button 16 and a movable ejector rod assembly inside the socket housing 11. The plug connector 20 includes a plug housing 21, a sliding rod 22 and a spring 23, and the sliding rod 22 and the spring 23 are assembled inside the plug housing 21; the button 16 is radially inserted into the button housing 15, a button spring 17 is pressed between the button housing 15 and the button 16, a locking bar 161 is provided in the button 16, and a stop slot 211 cooperating with the locking bar 161 of the button 16 is provided on the outer periphery of the plug housing 21.
[0032] The push-button structure design is achieved by fitting a button housing 15 on the socket 10, with the button 16 clamped inside the button housing 15. The setting of the button 16 is reset by the button spring 17. When the plug connector 20 is inserted into it, the button spring 17 is pressed down and automatically slides into it, and then the button spring 17 rebounds and pushes up, and the button 16 rebounds and resets, so that the locking bar 161 and the stop slot 211 on the plug housing 21 are docked and locked.
[0033] Please refer to the attached Figure 2 and the attached Figure 3 , the socket housing 11 and the button housing 15 of the socket 10 are connected to keep the central holes communicating. A button hole 151 is provided in the radial direction of the button housing 15, and the button 16 is pressed against the button spring 17 and inserted into the button housing 15.
[0034] The button 16 has a central through horizontal hole, which is in the same direction as the hole inside the socket housing of the socket 10.
