Description

Technical Field

[0001] This application relates to a connector, and more particularly to an anti-loosening liquid-cooled mating connector. 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-clamping connectors primarily use ball-shaped locking components that roll between the male and female terminals to prevent disassembly after mating. Other locking components with more complex structures are also designed to enhance the locking effect. While these locking or clamping components can prevent connectors from separating due to accidental contact or external forces, their resistance to tensile forces is still limited. Therefore, if the tensile force exceeds the limit, separation and potential liquid leakage are still possible.

[0010] In one embodiment, the backstop assembly includes a piston and a backstop element disposed on the piston, wherein the piston, with elastic force, pushes against and together with the backstop element, blocks the space between the socket and the cavity.

[0069] To gain a further understanding of the features and technical content of this application, please refer to the following detailed description and accompanying drawings. However, the accompanying drawings are for reference and illustration only and are not intended to limit this application.

[0070] Please see Figure 1 This is an exploded perspective view of the connecting device of this application. This application provides an anti-loosening liquid-cooled plug connector 1, which can be interconnected with a mating connector 2 to form a connecting device A, so as to connect to the pipeline (not shown) of a cooling system for liquid circulation. Figure 2 and Figure 3A As shown, the anti-loosening liquid-cooled plug connector 1 includes a plug body 10, an unlocking kit 11, a backstop kit 12, at least one first locking component 13, and at least one second locking component 14; wherein:

[0071] 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 cavity 100 for the anti-reverse kit 12 to be disposed therein. The cavity 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 cavity 100. The rear end of the connecting part 10b is provided with a pipe interface 10c so that the anti-loosening liquid-cooled plug connector 1 can be installed on the pipeline (not shown) of the cooling system for liquid circulation.

[0072] 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 and has a spring force that moves toward the front end of the body portion 10a; specifically, the movement stroke of the unlocking kit 11 on the plug-in body 10 does not exceed the end of the plug-in body 10, or the distance moved does not exceed the length of the plug-in body 10, etc. 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 cavity 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.

[0073] Please refer to the following: Figure 3A and Figure 3B As shown, the first 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 first actuating hole 102 around the periphery relative to the insertion port 101, and the first locking component 13 is movably disposed within the first actuating hole 102; when there are multiple first locking components 13, the number of first actuating holes 102 is also set to a corresponding number. This can be used in conjunction with... Figure 5 As shown, in this embodiment, the first locking component 13 has a limiting portion 130 located outside the first 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 first actuation hole 102. The locking portion 131 is smaller than the limiting portion 130 in radial dimension relative to the first actuation hole 102, so that when the first locking component 13 is provided in the first actuation hole 102, the locking portion 131 can be located in the first actuation hole 102 and will not fall into the insertion port 101.

[0074] Please refer to the following: Figure 3A and Figure 3C As shown, the second locking component 14 is also movably disposed on the body portion 10a of the aforementioned insertion body 10, and is arranged circumferentially around the aforementioned first locking component 13 relative to the insertion port 101, and can be arranged on the same circumference or staggered; specifically, the body portion 10a is provided with at least one second actuation hole 103 around the periphery of the insertion port 101, the second actuation hole 103 and the aforementioned first actuation hole 102 are arranged circumferentially around the body portion 10a, and the second locking component 14 is movably disposed within the second actuation hole 103; when there are multiple second locking components 14, the number of second actuation holes 103 is also set to a corresponding number. This can be used in conjunction with... Figure 5As shown, in this embodiment, the second locking assembly 14 has a positioning portion 140 located outside the second actuation hole 103, and a stop portion 141 that protrudes downward from the positioning portion 140 and can be radially (i.e., perpendicular to the aforementioned insertion or extraction direction) displaced within the second actuation hole 103. The stop portion 141 is smaller than the positioning portion 140 in radial dimension relative to the second actuation hole 103, so that when the second locking assembly 14 is provided within the second actuation hole 103, the stop portion 141 can be located within the second actuation hole 103 and will not fall into the insertion port 101. Meanwhile, the positioning portion 140 of the second locking assembly 14 may have a cross-section 140a on its side so that the positioning portion 140 can be embedded or partially embedded under the outer surface of the body portion 10a, thereby restricting the rotation between the second locking assembly 14 and the body portion 10a; of course, other structural designs may also be used to prevent its rotation, as long as the positioning portion 140 can be radially displaced within the second actuation hole 103 as described above.

[0075] like Figure 4 As shown, the aforementioned docking connector 2 is used to insert into the socket 101 of the anti-loosening liquid-cooled plug connector 1, thereby pushing the piston 120 inside the plug body 10 out of the backstop 121, and thus connecting the socket 101 with the cavity 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 anti-loosening 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 anti-loosening liquid-cooled plug connector 1.

[0076] Therefore, by using the above-described structure, the anti-loosening liquid-cooled connector of this application can be obtained.

[0077] Accordingly, Figure 5As shown, when the aforementioned anti-loosening liquid-cooling connector 1 is to be inserted with the mating connector 2, the mating connector 2 inserts its mating portion 201 into the socket 101 of the anti-loosening liquid-cooling connector 1. This insertion triggers the backstop mechanism 12 within the anti-loosening liquid-cooling connector 1, allowing them to communicate and supply liquid. In the embodiment described in this application, the mating portion 201 of the mating connector 2 pushes the piston 120 of the anti-loosening liquid-cooling connector 1 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 the liquid to flow between the anti-loosening liquid-cooled plug connector 1 and the mating connector 2, i.e. Figure 7 As shown.

[0078] Please see again Figures 6 to 8 As shown, in order to lock the anti-loosening liquid-cooled plug connector 1 and the mating connector 2 in place after insertion and maintain their insertion 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. Figure 6 As shown, when the anti-loosening liquid-cooled plug connector 1 and the mating connector 2 are about to connect internally, the pushing part 203 can push the first locking component 13 of the anti-loosening liquid-cooled plug connector 1. In this embodiment, the first locking component 13 has an actuating surface 131a protruding into the socket 101 through the first 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 mating connection... The pushing part 203 of the device 2 pushes the actuating surface 131a with its pushing surface 203a, so that the first locking component 13 slides radially outward on the pushing surface 203a with its actuating surface 131a, thereby passing over the pushing part 203 and inserting the docking part 201 into the plugging body 10, so that the first locking component 13 abuts against the back side of the pushing part 203 with its locking surface 131b. At the same time, the unlocking kit 11 has a spring force that moves toward the front end of the plugging body 10 to push the first locking component 13 forward and prevent it from retracting, thus unlocking it. Furthermore, the first locking component 13 has a contact surface 130a on the limiting portion 130, and the unlocking kit 11 has an annular anti-reverse surface 110 surrounding the inner surface of the unlocking kit 11, which cooperates to abut against the contact surface 130a, and elastically pushes the first locking component 13 to move axially within the first actuating hole 102, and as... Figure 8AAs shown, since both the abutment surface 130a and the anti-reverse surface 110 are mutually actuating inclined surfaces, the anti-reverse surface 110 generates an inclined force F1 on the abutment surface 130a to prevent the first locking component 13 from reversing and unlocking.

[0079] As described above, the second locking assembly 14 is also pushed radially outward by the pushing part 203 of the mating connector 2, so as to pass over the pushing part 203 and make the stop part 141 of the second locking assembly 14 abut against the back side of the pushing part 203, and make the unlocking kit 11 press against the positioning part 140, so as to make the second locking assembly 14 radially displaced within the second actuating hole 103, and as Figure 8B As shown, the unlocking kit 11 applies a radial force F2 to the positioning portion 140 of the second locking assembly 14 to ensure that the second locking assembly 14 is confined within the second actuating hole 103, thereby stably and reliably preventing the pushing portion 203 from reversing. Furthermore, the second locking assembly 14 has a recessed stop surface 141a on the stop portion 141 to abut against the back side of the pushing portion 203 to prevent it from reversing and being forcibly unlocked.

[0080] Conversely, such as Figure 9 As shown, when it is necessary to disconnect the anti-loosening liquid-cooled plug connector 1 and the mating connector 2, it is only necessary to push the unlocking kit 11 backward so that its anti-reverse surface 110 is away from the abutting surface 130a of the first locking component 13 and the unlocking kit 11 is not pressed against the positioning part 140 of the second locking component 14. Then the mating connector 2 can be quickly pulled off the anti-loosening liquid-cooled plug connector 1 to achieve the purpose of quick insertion and removal.

[0081] In addition, such as Figure 10 and Figure 11 As shown, the first locking component 13 can also be a sphere. The spherical first locking component 13 is movably inserted into the first actuation hole 102, so that a portion of the sphere passes through the first actuation hole 102 and actuates with the pushing portion 203 of the mating portion 201 of the mating connector 2, achieving the aforementioned locking or clamping effect. Simultaneously, the rolling of the sphere within the first actuation hole 102 also facilitates quick insertion or removal of the connecting device A.

[0082] Therefore, the anti-loosening liquid-cooled connector of this application further adds a second locking component 14 on the basis of the first locking component 13, and causes the unlocking kit 11 to generate the radial force F2 on the positioning part 140 of the second locking component 14. Since the radial force F2 is perpendicular to the direction of connector withdrawal, it can provide greater tensile strength to prevent the connector from being forcibly separated, thereby improving the stability and reliability during docking. This can also reduce the risk of loosening caused by vibration or external force, and reduce wear or abrasion under long-term use under this dual design, thereby extending the product life.

[0083] 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.
