Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connection socket and a fluid connector. Background Art

[0002] A fluid connector is a pipeline device and an important component for transmission connection in fluid transportation and gas transportation. It is used to achieve rapid connection and disconnection of pipelines and can ensure the sealing function of pipelines in any state, with fast operation and convenient maintenance. As an important component for connecting high-pressure fluid pipelines and controlling the on-off of pipelines, the connection of its plug and socket is particularly important.

[0003] In the prior art, the connection between the fluid connector socket and the plug mostly adopts a jaw connection. The automotive three-electric products (i.e., battery, electric drive, and electronic control) are usually produced by different manufacturers, and it is difficult to unify the cooling pipeline plugs of the three. There are not only multiple quick-connect plug standards such as MDC, SAE, and NW, but also slight differences in the plugs of the same specification produced by each manufacturer even under the same production conditions. The NW type plug is a quick-connect plug mostly used in automotive cooling water tanks and heat dissipation components and belongs to a standard quick-connect plug type in the industry. Exemplarily, there are several shapes for the NW 16 model plug. Among them, the dimensions of the main body that remain unchanged include the inner diameter, outer diameter of the plug, and the dimension of the groove between the transition slope and the lower half, and there are slight differences in the shapes and dimensions of other parts. The existing jaw connection requires different sockets to be replaced due to the different outer shapes of the plugs. During the testing of three-electric products, it is difficult to unify the sockets on the testing equipment for connecting to the cooling pipeline interfaces. During testing, different sockets need to be replaced for different plugs, which not only wastes a large amount of testing time, is troublesome to operate, but also increases the comprehensive cost of the testing equipment.

[0004] Therefore, it is necessary to provide a connection socket that can be compatible with multiple plugs of the same model. Summary of the Utility Model

[0047] In order to elaborate in detail the technical content and structural features of the present utility model, the following further explanations are provided in conjunction with the implementation manners and the accompanying drawings.

[0048] Please refer to Figures 1 to 3 , the present utility model provides a connection socket 100, which includes a housing 10, a sealing assembly 40, a push-pull assembly 30 and a locking assembly 20. Among them, the housing 10 has an accommodation cavity 101, and a gland 60 is installed at one end of the housing 10, and an installation activity space 102 is formed between the gland 60 and the housing 10. The sealing assembly 40 is elastically installed in the accommodation cavity 101 and can axially move in the accommodation cavity 101, that is, the sealing assembly 40 can axially move in the accommodation cavity 101 under the action of the plug 200, and make a sealing fit between the plug 200 and the connection socket 100. The push-pull assembly 30 is elastically sleeved on the housing 10 and can move between a first axial position and a second axial position to unlock the locked plug 200. The locking assembly 20 is installed on the housing 10 and is located in the installation activity space 102. The locking assembly 20 includes an elastic ring 22 and a locking member 21. The elastic ring 22 is elastically telescoped and sleeved on the locking member 21 and the housing 10, so that the locking member 21 is movably installed on the housing 10. The number of the elastic ring 22 and the locking member 21 is at least one, and the locking member 21 is movably arranged on the housing 10 through an elastic member. Specifically, a hook portion 211 is provided at one end of the locking member 21, and the hook portion 211 passes through the housing 10 and is placed in the accommodation cavity 101. A driving inclined surface 2111 is provided on the hook portion 211. The driving inclined surface 2111 is pushed to drive the locking member 21 to elastically move within a preset range, so that the plug 200 can be smoothly inserted into the connection socket 100, and then the hook portion 211 elastically resets and engages with the plug 200 to lock the plug 200 in the connection socket 100. When it is necessary to unlock the plug 200, the push-pull assembly 30 is moved from the first position to the second position to drive the locking member 21 to move radially to the unlocked state. It can be understood that the first position is the position where the limiting block 321 of the push-pull ring 32 abuts against the end cover 50, that is, the initial position where the push-pull ring 32 moves. The second position is to push the push-pull ring 32 so that the limiting block 321 disengages from the end cover 50 and drives the pressing ring 31 to squeeze the locking member 21, so that the locking member 21 moves radially until the hook portion 211 disengages from the plug 200 to unlock the plug 200.

[0049] After adopting the above technical solution, the connection socket 100 of the present utility model locks the plug 200 through the elastically movable locking member 21, and cooperates with the elastically movable sealing assembly 40 to seal the plug 200 and the connection socket 100, with good sealing effect; the connection socket 100 can be applicable to a variety of plugs 200 of the same model, with a wide range of applications. The connection socket 100 includes a housing 10, a sealing assembly 40, a push-pull assembly 30, and a locking assembly 20. The housing 10 has a receiving cavity 101, and a gland 60 is installed at one end, and an installation and movement space 102 for installing and moving the locking assembly 20 is formed between the gland 60 and the housing 10. The sealing assembly 40 is elastically installed in the receiving cavity 101 and can axially move in the receiving cavity 101. The sealing assembly 40 can elastically move in the receiving cavity 101 to adapt to plugs 200 of different lengths, so that plugs 200 of different lengths can be hermetically fitted with the connection socket 100. The push-pull assembly 30 is elastically sleeved on the housing 10 and can move between a first axial position and a second axial position. By operating the push-pull assembly 30 to move from the first position to the second position, the plug 200 can be unlocked in the connection socket 100, and the operation is convenient. Specifically, the locking assembly 20 is installed on the housing 10 and is located in the installation and movement space 102. The locking assembly 20 includes an elastic ring 22 and a locking member 21. The elastic ring 22 is sleeved on the locking member 21 and the housing 10, so that the locking member 21 is movably installed on the housing 10, that is, the locking member 21 is movably connected to the housing 10 through the elastic ring 22. One end of the locking member 21 is provided with a hook portion 211. The hook portion 211 passes through the housing 10 and is placed in the receiving cavity 101. A driving inclined surface 2111 is provided on the hook portion 211. By pushing the driving inclined surface 2111, the locking member 21 can elastically move within a preset range and can be locked. Push and pull the push-pull assembly 30 from the first position to the second position to drive the locking member 21 to move radially to the unlocked state. The unlocking of the connection socket 100 can be completed by moving the push-pull assembly 30, and the operation is convenient. The connection socket 100 of the present utility model can be applicable to a variety of plugs 200 of the same model, with a wide range of applications and convenient operation.

[0050] Please refer to Figures 2 to 4 , in some alternative embodiments, an installation groove 11 for installing the locking member 21 is formed on the housing 10. A through groove 12 is also formed through the housing 10. The locking member 21 is installed in the installation groove 11, and the hook portion 211 passes through the through groove 12 and is placed in the receiving cavity 101. Among them, a convex portion protrudes on the outer circumference of the housing 10. The installation groove 11 is formed in the convex portion. The locking member 21 is installed in the installation groove 11 and, with the cooperation of the pressing ring 31, the locking member 21 and the housing 10 are substantially integrated, with a compact and reasonable fit.

[0051] Please refer to Figures 2 to 4, in some alternative embodiments, a first groove 13 for installing the elastic ring 22 is further formed on the housing 10, and a second groove 212 for installing the elastic ring 22 is formed on the locking member 21. The locking member 21 is installed in the housing 10 to communicate the first groove 13 with the second groove 212. In this embodiment, the number of the locking members 21 is two, and the number of the elastic rings 22 is also two. Correspondingly, the number of the first grooves 13 and the second grooves 212 is equal to the number of the elastic rings 22. It can be understood that the two locking members 21 can lock the plug 200 from both sides, and the locking is more stable and reliable. The structure of the double elastic rings 22 can make the force received by the locking member 21 during radial movement more uniform, thereby preventing the locking member 21 from skewing, and the overall structure is more stable and reliable. Of course, the number of the locking members 21 can also be three or other appropriate numbers, and the number of the elastic rings 22 can also be three or other appropriate numbers, as long as the plurality of elastic rings 22 can firmly fix the plurality of locking members 21 on the housing 10. Among them, the elastic ring 22 can be an elastic ring structure made of plastic material, such as an O-ring. The elastic ring 22 can also be a ring structure formed by connecting the heads and tails of slender tension springs or springs. As long as the elastic ring 22 has a certain elasticity and a stable structure capable of fixing the locking member 21 on the housing 10.

[0052] Please refer to Figure 2 , Figure 3 and Figure 5 and Figure 6, in some alternative embodiments, the push-pull assembly 30 includes a pressure ring 31 mounted on the housing 10. The pressure ring 31 has a hollow structure and is sleeved on the housing 10 through a hollow first cavity 301. A first step portion 213 cooperating with the pressure ring 31 is provided on the locking member 21, and a second step portion 311 cooperating with the first step portion 213 is provided on the pressure ring 31. The first step portion 213 and the second step portion 311 are in clearance fit. That is, a gap is left between the first step portion 213 of the locking member 21 and the second step portion 311 of the pressure ring 31 to prevent the entire structure from jamming and making it difficult to unlock the plug 200 due to machining tolerance problems in the case of a completely fitting design. Among them, the first step portion 213 includes a first inclined surface 2131 and a second inclined surface 2132. A first flat surface 2133 is provided between the first inclined surface 2131 and the second inclined surface 2132, and a second flat surface 2134 is provided on the other side of the second inclined surface 2132. On the other hand, the second step portion 311 includes a third inclined surface 3111 and a fourth inclined surface 3112. A third flat surface 3113 is provided between the third inclined surface 3111 and the fourth inclined surface 3112, and a fourth flat surface 3114 is provided on the other side of the fourth inclined surface 3112. During installation, the third inclined surface 3111 cooperates with the first inclined surface 2131, the fourth inclined surface 3112 cooperates with the second inclined surface 2132, the first flat surface 2133 cooperates with the third flat surface 3113, and the second flat surface 2134 cooperates with the fourth flat surface 3114. In addition, the locking member 21 further includes a flat portion 214 abutted against the housing 10. Specifically, when unlocking, the pressure ring 31 is pushed to cause the third inclined surface 3111 to squeeze the first inclined surface 2131 and slide along the first inclined surface 2131. At the same time, the fourth inclined surface 3112 squeezes the second inclined surface 2132 and slides along the second inclined surface 2132, while the third flat surface 3113 gradually disengages from the first flat surface 2133, and the fourth flat surface 3114 also gradually disengages from the second flat surface 2134. Under the push-pull action, the third inclined surface 3111 continuously squeezes and pushes the first inclined surface 2131 and extends to the flat portion 214 to cause the flat portion 214 to disengage from the housing 10. Since the locking member 21 is installed in the installation groove 11, the two sides of the locking member 21 cooperate with the two side surfaces of the installation groove 11 and will not slide along the circumferential direction of the housing 10. With the continuous pushing of the pressure ring 31, one end of the locking member 21 provided with the hook portion 211 abuts against the pushing surface 111, and under the limitation of the pushing surface 111, the locking member 21 slides radially along the pushing surface 111 until the hook portion 211 disengages from the plug 200 to unlock the plug 200.

[0053] Please refer to Figure 2 and Figure 9, in some alternative embodiments, a gland 60 is installed outside the locking member 21. A second sealing ring 61 is provided between the gland 60 and the housing 10 to make the gland 60 and the housing 10 hermetically arranged. Among them, the gland 60 is provided with fixing blocks 62 that cooperate with the housing 10. The housing 10 is provided with a groove 16 for installing the second sealing ring 61 and a fixing groove 17 that cooperates with the fixing blocks 62. The fixing blocks 62 are snap-fitted into the fixing groove 17 so that the gland 60 is installed on the housing 10 and can fix the second sealing ring 61 in the groove 16. The provision of the gland 60 can not only effectively protect the locking member 21 and the elastic ring 22, but also prevent the locking member 21 from detaching from the housing 10 when moving radially. The gland 60 can limit the radial movement range of the locking member 21. The gland 60 is installed on the housing 10 and forms an installation and movement space 102 for the locking member 21 to move radially between it and the housing 10. On the other hand, one end of the gland 60 extends into the installation and movement space 102 to cooperate with the locking member 21, and the pushing and pulling movement of the pushing and pulling assembly 30 does not interfere with the gland 60.

[0054] Please refer to Figure 2 and Figure 6 , in some alternative embodiments, the pushing and pulling assembly 30 further includes a pushing and pulling ring 32 and a first elastic member 33. The pushing and pulling ring 32 is provided with a hollow second cavity 302 and is sleeved on the housing 10 through the second cavity 302. One end of the pushing and pulling ring 32 is threadedly connected to the second thread portion 312 at one end of the pressing ring 31 through a third thread portion 322 to form an integral structure. A receiving space 303 for accommodating the first elastic member 33 is provided between the pushing and pulling ring 32 and the housing 10. Pushing and pulling the pushing and pulling ring 32 in the direction towards the pressing ring 31 drives the pressing ring 31 to squeeze the locking member 21, and the pushing and pulling ring 32 squeezes the first elastic member 33 in the receiving space 303, and the squeezed first elastic member 33 always has a tendency to reset. On the other hand, a limiting block 321 is provided at one end of the pushing and pulling ring 32 away from the pressing ring 31 in the receiving space 303. A limiting step 14 is provided on the housing 10, and a limiting member 34 is installed on the limiting step 14. The limiting step 14 can be used to limit the limiting member 34 or the first elastic member 33. The first elastic member 33 is installed in the receiving space 303 and one end abuts against the limiting block 321 and the other end abuts against the limiting member 34. Among them, the limiting member 34 can be a gasket. The provision of the gasket can better support the first elastic member 33 so as to better compress the first elastic member 33.

[0055] Please refer to Figure 2 and Figure 8, in some alternative embodiments, one end of the housing 10 is provided with a first threaded portion 15, and the first threaded portion 15 is connected to the fourth threaded portion 51 of the end cap 50. The end cap 50 is provided with a third cavity 501 communicating with the accommodation cavity 101. The other end of the end cap 50 is provided with a fifth threaded portion 52 capable of connecting to other components. Among them, the limiting block 321 of the push-pull ring 32 abuts against the end cap 50 at a first position at the end away from the first elastic member 33. On the other hand, the sealing assembly 40 includes a second elastic member 41 and a sealing ring 42.

The other end of the second elastic member 41 abuts against the sealing ring 42, and a limiting portion 18 for limiting the sealing ring 42 is provided within the accommodation cavity 101. In addition, at least one sealing groove 421 is formed on the sealing ring 42, and a first sealing ring 44 is installed within the sealing groove 421. The first sealing ring 44 fits against the inner wall of the accommodation cavity 101 so that the sealing ring 42 and the housing 10 are in sealing cooperation. On the other hand, the sealing assembly 40 further includes a waterproof ring 43. An installation portion 422 for installing the waterproof ring 43 is provided within the sealing ring 42. The waterproof ring 43 is installed within the installation portion 422 and one end abuts against the limiting portion 18. A sealing cooperation portion 431 that is recessed inward is provided at the end of the waterproof ring 43 away from the second elastic member 41. The plug 200 extends into the sealing cooperation portion 431, and the sealing cooperation portion 431 can elastically fit against the end of the plug 200 so that the plug 200 and the connection socket 100 are in sealing cooperation.

[0056] Please refer to Figures 10 to 13 , the present utility model further provides a fluid connector 1000, including a plug 200, and the types of the plug 200 include but are not limited to Figures 11 to 13Type. The fluid connector 1000 further includes the above-mentioned connection socket 100. Specifically, the plug 200 includes a sealing end 203 and an engaging portion 202. One end of the engaging portion 202 is provided with a pushing inclined surface 201 that cooperates with the driving inclined surface 2111. When the plug 200 is inserted into the connection socket 100, the pushing inclined surface 201 pushes the driving inclined surface 2111 and causes the engaging hook portion 211 to elastically expand radially outward until the engaging hook portion 211 slides to the engaging portion 202 and is engaged and locked within the engaging portion 202. At the same time, the sealing end 203 of the plug 200 squeezes the sealing assembly 40 to elastically move, and enables the sealing end 203 to be in sealing cooperation with the sealing assembly 40. It can be understood that since the sealing assembly 40 is provided with the second elastic member 41, the sealing assembly 40 has a certain elastic movement range and can be applicable to plugs 200 of different lengths, with a wider application range. Among them, the pushing inclined surface 201 has a gradually changing structure with a gradually increasing cross-section from one end of the sealing end 203 to one end of the engaging portion 202, and the pushing inclined surface 201 can be an arc-shaped curved surface. The engaging portion 202 can be a groove recessed inward, or a recessed structure that cooperates with the pushing inclined surface 201, as long as a recessed structure can be formed on one side of the pushing inclined surface 201 to accommodate the engaging hook portion 211. The specific structure of the engaging portion 202 can be set according to the specific structure requirements of the plug 200. As long as the engaging hook portion 211 can cooperate with the engaging portion 202 to limit the plug 200 axially, the locking of the plug 200 can be completed. When unlocking, the push-pull assembly 30 is pushed and pulled to move from the first position to the second position, so as to drive the locking member 21 to move radially to disengage from the engaging portion 202 to unlock the plug 200. At this time, due to the cancellation of the pressure of the second elastic member 41, the second elastic member 41 drives the sealing assembly 40 to elastically reset and the plug 200 automatically exits the connection socket 100, and the operation is convenient and simple. As Figure 3 , Figure 4 and Figures 11 to 13 shown, at least one slot 19 that cooperates with the plug 200 wire is further opened on the housing 10, and at least one convex 204 that is adapted to the slot 19 is protrudingly provided on the plug 200. Through the cooperation of the convex 204 and the slot 19, the plug 200 can be circumferentially limited, making the overall connection more stable and reliable. The fluid connector 1000 connection socket 100 of the present invention can cooperate with a variety of specifications of plugs 200 of the same model. For different plugs 200, there is no need to replace the socket, which saves a large amount of test time in testing, is more convenient to operate, and reduces the comprehensive cost of the test equipment. In addition, the cooperation between the connection socket 100 and the plug 200 is more convenient for installation, more convenient for disassembly, and more stable in cooperation.

[0057] As Figures 1 to 13As shown in the figure, the fluid connector 1000 of the present utility model includes a connection socket 100 and a plug 200. The connection socket 100 locks the plug 200 through an elastically movable locking member 21, and cooperates with an elastically movable sealing assembly 40 to make the plug 200 and the connection socket 100 sealed. It not only has a good sealing effect, but also can be applicable to plugs 200 of different lengths. The connection socket 100 can be applicable to a variety of plugs 200 of the same model, with a wide application range. The connection socket 100 of the present utility model can be applicable to a variety of existing plugs 200. There is no need to replace the socket for different plugs 200, which saves a lot of test time in the test, is more convenient to operate, and reduces the comprehensive cost of the test equipment. Whether the connection socket 100 of the present utility model is inserted and cooperated with the plug 200 or unlocked, the operation is fast and convenient, greatly improving the efficiency.
