Description

Technical Field

[0001] This application relates to a connector, and more particularly to a liquid-cooled plug connector and its connecting device. Background Technology

[0002] In existing cooling systems that use liquid as a circulating heat source, the pipes used to transport the liquid often need to be replaced or quickly connected via quick couplings or other means.

[0003] However, existing quick-connect couplings or fast-connector connectors mainly use a ball-shaped locking component that rolls between the male and female terminals to prevent disassembly after mating. This prevents the connectors from detaching due to accidental contact or external forces, thus avoiding accidents such as liquid leakage. However, because the ball-shaped locking component can still roll freely during mating, the male and female terminals may still detach under certain external pulling forces, potentially leading to the aforementioned accidents.

[0004] In view of this, in order to improve and solve the above-mentioned deficiencies, the applicant has devoted himself to research and applied theoretical principles, and finally proposed a design that is reasonable and effective in improving the above-mentioned deficiencies. Summary of the Invention

[0005] The main objective of this application is to provide a liquid-cooled plug connector and its connecting device, which uses components for locking male and female connectors, and is designed with more bevels to achieve a locking effect, thereby providing better tensile strength and preventing the connector from coming off.

[0006] To achieve the above objectives, this application provides a liquid-cooled plug connector, including a plug body, an unlocking kit, a backstop kit, and at least one locking component. The plug body has a hollow area extending towards the front end of the plug body to form a socket, and the plug body further has at least one actuating hole around the socket. The unlocking kit is elastically fitted onto the plug body. The backstop kit is disposed within the hollow area and elastically blocks the socket from the hollow area. The locking component is movably disposed within the actuating hole and has a limiting portion located outside the actuating hole and a locking portion protruding downward from the limiting portion and capable of axial displacement within the actuating hole. The locking component has an actuating surface protruding through the actuating hole into the socket and a locking surface opposite to the actuating surface on the locking portion. The unlocking kit has a backstop surface, and the backstop surface elastically pushes against the limiting portion to cause the locking component to axially displace outward within the actuating hole.

[0007] In one embodiment, the plug-in body includes a body portion and a connector portion, with the hollow area located inside the body portion, and the connector portion fitted onto the body portion and sealing the hollow area.

[0011] In one embodiment, the limiting part is provided with an abutting surface that cooperates with the anti-reverse surface to abut.

[0012] In one embodiment, the anti-return surface is annular.

[0013] To achieve the above objectives, this application provides a connection device, including a mating connector and the aforementioned liquid-cooled plug-in connector; wherein, when the mating connector is inserted into the socket of the plug-in body, it is pushed against the actuating surface to cause the locking component to slide and the latching surface to latch the mating connector, and the unlocking kit has a reversible surface, which elastically pushes against the limiting part to cause the locking component to move axially outward within the actuating hole.

[0014] In one embodiment, the docking connector includes a docking body and a sealing kit disposed within the docking body.

[0017] In one embodiment, the plug-in body includes a body portion and a connector portion, with the hollow area located inside the body portion, and the connector portion fitted onto the body portion and sealing the hollow area.

[0018] In one embodiment, the backstop assembly includes a piston and a backstop member disposed on the piston, wherein the piston is elastically pushed against and together with the backstop member is blocked between the socket and the hollow area.

[0065] To enable your examination committee to better understand the features and technical content of this application, please refer to the following detailed description and drawings of this application. However, the accompanying drawings are for reference and illustration only and are not intended to limit this application.

[0066] Please see Figure 1 This is an exploded perspective view of the connection device of this application. This application provides a liquid-cooled plug connector and its connection device, the connection device including the liquid-cooled plug connector 1 and a mating connector 2 that is interconnected with the liquid-cooled plug connector 1; as shown... 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 plug-in body 10, and the elastic component 11a abuts against the plug-in body 10, having 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 locking portion 131 that protrudes downward from the limiting portion 130 and can be axially (i.e., in the insertion or removal direction, with the insertion direction being axially inward and the removal direction being axially outward) within the actuation hole 102. The locking portion 131 is smaller than the limiting portion 130 in radial dimension relative to the actuation hole 102, so that when the locking assembly 13 is provided in the actuation hole 102, the locking portion 131 can be located in the actuation hole 102 and will not fall into the insertion port 101.

[0070] like Figure 4 As shown, the aforementioned docking connector 2 is used to insert into the socket 101 of the liquid-cooled plug connector 1, thereby pushing the piston 120 inside the plug body 10 out of the check valve 121, and thus connecting the socket 101 with the hollow area 100 to allow liquid to flow. The docking connector 2 includes a docking body 20 and a sealing kit 21 disposed within the docking body 20; wherein, the docking body 20 may have a base 200 and a docking portion 201 extending axially 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 installed on the pipeline (not shown) of the cooling system for liquid circulation, and connect to the liquid circuit after being plugged into the liquid-cooled plug connector 1. The sealing kit 21 is located inside the docking portion 201 and includes a pusher 210 and an elastic component 211 for pushing the pusher 210 forward to close the docking portion 201, so that the docking connector 2 can also prevent liquid from flowing out of the pipe (not shown) it is connected to when it is not plugged into the liquid-cooled plug connector 1.

[0071] Therefore, by means of the above-described structure, the liquid-cooled plug connector and its connecting device of this application can be obtained.

[0072] Accordingly, Figure 5 As shown, when the liquid-cooled plug connector 1 is to be plugged into the mating connector 2, the mating connector 2 inserts its mating portion 201 into the socket 101 of the liquid-cooled plug connector 1. This plugging action triggers the actuation of the backstop assembly 12 within the liquid-cooled plug connector 1, thereby establishing communication and allowing liquid flow. In the embodiment described in this application, the mating portion 201 of the mating connector 2 pushes the piston 120 of the liquid-cooled plug connector 1 to move backward; as... Figure 6 As shown, when the piston 120 moves backward and disengages from the backstop 121, the backstop 121 also extends into the mating portion 201 of the mating connector 2, pushing the pusher 210 of the sealing kit 21 backward, thereby allowing liquid to flow between the liquid-cooled plug connector 1 and the mating connector 2, i.e. Figure 7 As shown.

[0073] Please see again Figures 6 to 8 As shown, in order to lock the liquid-cooled plug connector 1 and the mating connector 2 in place after insertion and maintain their plugged state, the mating portion 201 of the mating connector 2 is provided with a pushing portion 203 on its outer ring, and the pushing portion 203 has an inclined pushing surface 203a in the direction of mating; as Figure 6 As shown, when the liquid-cooled plug connector 1 and the mating connector 2 are about to connect internally, the pushing part 203 can push the locking component 13 of the liquid-cooled plug connector 1. The locking component 13 has an actuating surface 131a protruding into the socket 101 through the actuating hole 102 and a locking surface 131b opposite to the actuating surface 131a. The actuating surface 131a faces outward from the socket 101, while the locking surface 131b faces inward from the socket 101. The pushing of the mating connector 2... The part 203 pushes its pushing surface 203a towards the actuating surface 131a, allowing the locking assembly 13 to slide upwards on the pushing surface 203a with its actuating surface 131a. This allows the mating part 201 to be inserted into the insertion body 10, passing over the pushing part 203. The locking assembly 13 then rests against the back side of the pushing part 203 with its locking surface 131b. Simultaneously, the unlocking kit 11, with its elastic force moving towards the front end of the insertion body 10, pushes the locking assembly 13 forward and prevents it from retracting, thus unlocking it. Furthermore, the locking assembly 13 has a stop surface 130a on the limiting part 130, and the unlocking kit 11 has an annular anti-reverse surface 110 that abuts against the stop surface 130a to prevent the locking assembly 13 from retracting and unlocking.

[0074] Conversely, such as Figure 9 As shown, when you want to disconnect the liquid-cooled plug connector 1 and the docking connector 2, you only need to push the unlocking kit 11 backward so that its anti-reverse surface 110 is away from the abutment surface 130a of the locking component 13, and then the docking connector 2 can be quickly pulled off the liquid-cooled plug connector 1 to achieve the purpose of quick plugging and unplugging.

[0075] However, the above description is only a preferred embodiment of this application and does not limit the patent scope of this application. Therefore, all equivalent technical and means changes made based on the content of this application specification and drawings are also included in the scope of this application and are hereby stated.
