[0065] For the further understanding of the features and technical contents of the present application, please refer to the following detailed description and drawings of the present application. However, the drawings are provided for reference and illustration only, and are not intended to limit the present application.

[0066] Please refer to Figure 1 , the exploded view of the connecting device of the present application. The present application provides a liquid-cooled plug-in connector and a connecting device thereof, which comprises the liquid-cooled plug-in connector 1 and the mating connector 2 connected with the liquid-cooled plug-in connector 1; as shown in Figure 2 and Figure 3AAs shown, the liquid-cooled plug connector 1 includes a plug body 10, an unlocking kit 11, a backstop kit 12, and at least one locking component 13; wherein:

[0067] like Figure 2 and Figure 3A As shown, the plug-in body 10 is used to allow the unlocking kit 11 to be flexibly and movable outside, and to allow the anti-reverse kit 12 to be disposed inside. In the embodiments described in this application, it can be used in conjunction with... Figure 5 As shown, the plug-in body 10 may include a body part 10a and a connecting part 10b. The body part 10a has a hollow area 100 for the backstop kit 12 to be disposed therein. The hollow area 100 extends to the front end of the body part 10a and communicates to form a plug 101. The connecting part 10b is sleeved on the rear end of the body part 10a and closes the hollow area 100. The rear end of the connecting part 10b is provided with a pipe interface 10c so that the liquid-cooled plug-in connector 1 can be installed on the pipeline (not shown) of the cooling system for liquid circulation.

[0068] like Figure 2 As shown, the unlocking kit 11 is movably sleeved on the outside of the aforementioned plug-in body 10, and the elastic component 11a abuts against the plug-in body 10 and has a spring force that moves toward the front end of the body portion 10a. Figure 3A As shown, the backstop assembly 12 includes a piston 120 and a backstop member 121 disposed on the piston 120. The piston 120 is pushed by the elastic force of the elastic component 120a and together with the backstop member 121, it is blocked between the insertion port 101 and the hollow area 100 (i.e., as shown). Figure 5 As shown), this allows the liquid in the cooling system to enter the plug body 10 from the pipe interface 10c, so that the liquid can be blocked by the backstop kit 12 and will not overflow from the plug 101.

[0069] Please refer to the following: Figure 3A and Figure 3B As shown, the locking component 13 is movably disposed on the body portion 10a of the aforementioned insertion body 10, and relative to the insertion port 101; specifically, the body portion 10a has at least one actuation hole 102 around the periphery relative to the insertion port 101, and the locking component 13 is movably disposed within the actuation hole 102; when there are multiple locking components 13, the number of actuation holes 102 is also set to a corresponding number. It can be used in conjunction with... Figure 5As shown, the locking assembly 13 has a limiting portion 130 located outside the actuation hole 102, and a clamping portion 131 protruding downward from the limiting portion 130 and axially (i.e. the direction of insertion or extraction, and the direction of insertion is axially inward, and the direction of extraction is axially outward) displaceable within the actuation hole 102, the clamping portion 131 is smaller than the limiting portion 130 in the radial dimension relative to the actuation hole 102, so that when the locking assembly 13 is arranged in the actuation hole 102, the clamping portion 131 can be located within the actuation hole 102 and not fall into the socket 101.

[0070] As shown, Figure 4 The docking connector 2 is used to insert the socket 101 of the liquid-cooled plug-in connector 1, so as to push the piston 120 in the plug-in body 10 away from the check member 121, and then make the socket 101 communicate with the hollow area 100 to allow the liquid to flow. The docking connector 2 includes a docking body 20 and a sealing assembly 21 arranged in the docking body 20; wherein the docking body 20 can have a base 200 and a docking portion 201 axially extending forward from the base 200, and a pipe interface 202 protruding rearward from the base 200, so that the docking connector 2 can also be arranged on the pipe (not shown) of the cooling system for circulating liquid, and communicate with the liquid-cooled plug-in connector 1 after being plugged in. The sealing assembly 21 is arranged in the docking portion 201 and includes a pushing member 210 and a resilient assembly 211 for pushing the pushing member 210 forward to seal the docking portion 201, so that the docking connector 2 can also prevent the liquid in the pipe (not shown) connected thereto from flowing out when it is not plugged in with the liquid-cooled plug-in connector 1.

[0071] Therefore, by the above structure, the liquid-cooled plug-in connector and its connecting device can be obtained.

[0072] Accordingly, as shown, Figure 5 When the liquid-cooled plug-in connector 1 is plugged in with the docking connector 2, the docking portion 201 of the docking connector 2 is inserted into the socket 101 of the liquid-cooled plug-in connector 1, so that the check sleeve 12 in the liquid-cooled plug-in connector 1 is triggered to actuate by the action of being plugged in with each other, so that they are communicated to allow the liquid to pass through. In the embodiment of the present application, the docking portion 201 of the docking connector 2 pushes the piston 120 of the liquid-cooled plug-in connector 1 to move rearward; as shown, Figure 6 When the piston 120 moves rearward and is separated from the check member 121, the check member 121 also extends into the docking portion 201 of the docking connector 2 to push the pushing member 210 of the sealing assembly 21 rearward, so that the liquid-cooled plug-in connector 1 and the docking connector 2 can be communicated to allow the liquid to flow, as shown, Figure 7 as shown.

[0073] Please refer to Figures 6 to 8 As shown, in order to lock the liquid cooling plug-in connector 1 and the mating connector 2 after plugging to maintain the plugging state, the outer ring of the mating part 201 of the mating connector 2 is provided with a pushing part 203, and the pushing part 203 has an inclined pushing surface 203a in the direction of the mating. Figure 6 As shown, when the liquid cooling plug-in connector 1 and the mating connector 2 are about to communicate with each other, the pushing part 203 can just push the locking assembly 13 of the liquid cooling plug-in connector 1, and the locking assembly 13 has an actuating surface 131a protruding into the socket 101 through the actuating hole 102 and a clamping surface 131b opposite to the actuating surface 131a on the clamping part 131. The actuating surface 131a faces outward of the socket 101, and the clamping surface 131b faces inward of the socket 101. The pushing part 203 of the mating connector 2 pushes the actuating surface 131a with the pushing surface 203a, so that the locking assembly 13 slides upward on the pushing surface 203a with the actuating surface 131a, and then passes the pushing part 203 to make the mating part 201 inserted into the plug-in body 10, so that the locking assembly 13 is turned by the clamping surface 131b abutting against the back side of the pushing part 203, and the above-mentioned unlocking sleeve 11 has a spring force moving towards the front end of the plug-in body 10 to push the locking assembly 13 forward and prevent it from being unlocked. Further, the locking assembly 13 is provided with an abutting surface 130a on the limiting part 130, and the unlocking sleeve 11 is provided with an annular check surface 110 and cooperates with the abutting surface 130a to prevent the locking assembly 13 from being unlocked by reversing.

[0074] On the contrary, as shown, when the liquid cooling plug-in connector 1 and the mating connector 2 are about to be unplugged, the unlocking sleeve 11 is only needed to be pushed backward, so that the check surface 110 is away from the abutting surface 130a of the locking assembly 13, and then the mating connector 2 can be quickly pulled out of the liquid cooling plug-in connector 1 to achieve the purpose of quick plugging and unplugging.
