Description

A connecting end, fluid connector and liquid cooling device

[0001] The present application claims priority to the Chinese patent application No. 202421087707.6, filed on May 17, 2024, and entitled "A connecting end, fluid connector and liquid cooling device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of connectors, more particularly, to a connecting end, fluid connector and liquid cooling device. BACKGROUND

[0003] At present, the requirement for the operation speed of various chips is higher and higher due to the interconnection of all things, resulting in higher and higher requirement for the heat dissipation of chips. The traditional air cooling heat dissipation cannot meet the heat dissipation requirement of chips, and various new fluid heat sinks will become the mainstream of chip heat dissipation, and the fluid connector is an interface between the fluid source and various chip heat sinks.

[0004] The fluid connector usually includes two connecting ends matched with each other, and the structures of the two connecting ends can be the same or different. When the fluid source is disconnected, the two connecting ends are individually sealed to prevent fluid leakage and spraying. When the two connecting ends are connected, the sealing structures of the two connecting ends are opened, so that the fluid source and the fluid heat sink are connected, the fluid circulates to take away heat, and the fluid connector plays a role of efficient heat dissipation.

[0005] In the process of implementing the present application, the inventors found at least the following problems in the prior art:

[0006] A common connecting end includes a valve core and a valve seat. The valve core is usually integrally arranged inside the valve seat. The valve seat has a flow channel extending to the end face of the valve seat. The valve core has a through hole. The valve core is movable to change the relative position of the through hole and the flow channel, so as to switch the opening and closing states of the connecting end. However, since the fluid pressure in the connecting end is usually large, in the closed state of the valve core, the pressure of the fluid on the valve core and the friction force acting on the valve core make the activity resistance of the valve core large, so that it is more laborious to operate the connecting end. Therefore, it is necessary to provide a connecting end, fluid connector and liquid cooling device to solve the above technical problems. SUMMARY

DETAILED DESCRIPTION

[0034] The connecting end, the fluid connector and the liquid cooling device provided by the embodiments of the present application can directly contact the valve core with the counter-connection end, and the outer end surface of the valve core and the valve body do not need to be sealed, so that the resistance of the sealing structure to the valve core is reduced, the operation is facilitated, and the turbulent flow is not easily formed.

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0036] The connecting end provided by the present application is used for cooperating with the counter-connection end, and the structure of the counter-connection end can be the same as or partially different from that of the connecting end. When the fluid source is disconnected, the connecting end and the counter-connection end are individually sealed; when the connecting end and the counter-connection end are connected, they are respectively opened, so that the connecting end and the counter-connection end can form a continuous fluid channel. The connecting end comprises a valve seat and a valve core, and the valve core is constrained to be movable relative to the valve seat within a preset range. A through hole is arranged on the valve core, and a flow channel is arranged on the valve seat, and when the valve core is moved to the position that the through hole is communicated with the flow channel, the connecting end is opened, and when the valve core is moved to the position that the through hole is misaligned with the flow channel, the connecting end is closed. Specifically, when the valve core is moved to the position that the through hole is opposite to the flow channel, the connecting end is opened, and when the valve core is moved to the position that the through hole is misaligned with the flow channel, the connecting end is closed. It can be understood that the communication between the through hole of the valve core and the flow channel can mean that the through hole and the flow channel are at least partially opposite to each other to communicate, or that the through hole and the flow channel are directly opposite to each other to communicate, so that the fluid in the flow channel can flow into the other end of the flow channel through the through hole, and the connecting end is opened. The misalignment between the through hole of the valve core and the flow channel means that the through hole and the flow channel are completely misaligned to not communicate, so that the fluid in the flow channel cannot flow under the blocking action of the valve core, that is, the connecting end is closed.

[0037] In order to realize the sealing of the overall continuous channel and the outside world in the connected state of the connecting end and the counter-connection end, the sealing gaskets need to be arranged between the valve core and the valve body on both sides of the valve core and between the two valve seats. The inventor of the present application found in the process of realizing the present application that the damping force formed by the sealing gaskets between the valve core and the valve seat and between the two valve seats will become the resistance of the valve core rotation. And under the condition of poor sealing, the fluid is easy to flow on the matching surface between the valve core and the valve seat, thereby forming a turbulent flow. In order to overcome the above defects, the present application provides a connecting end which reduces the resistance of the valve core rotation and the risk of causing turbulent flow through the structural design of the valve core and the valve seat. In the following embodiments, the structure and matching mode of the valve core and the valve seat are mainly described.

[0038] In some embodiments, referring to FIG. 1-2, the connection end provided by the present application comprises a valve seat 100, a valve core 200 and a first sealing member 300. The valve seat 100 is provided with a flow channel 110, and one end of the valve seat 100 is provided with an opening 120. The valve core 200 is movably arranged in the valve seat 100, for example, is axially movably arranged in the valve seat 100, and the outer end of the valve core 200 is arranged in the opening 120, so that the outer end surface 230 of the valve core 200 can be in contact with the mating end, and the through hole 201 of the outer end surface 230 of the valve core 200 directly communicates with the mating end without passing through the flow channel 110 of the valve seat 100 of the connection end. It can be understood that the opening 120 communicates with the flow channel 110, and the shape of the opening 120 can be the same as or different from that of the flow channel 110. The valve core 200 is provided with a through hole 201 extending to the outer end surface 230 of the valve core 200, and the size of the opening 120 is greater than that of the through hole 201, so that the outer end surface can be used for cooperating with the mating end corresponding to the connection end, and the valve core 200 can be moved to make the through hole 201 communicate with the flow channel 110 and the through hole 201 deviate from the flow channel 110. That is, the outer end surface 230 of the valve core 200 is exposed from the opening 120, that is, the outer end surface 230 of the valve core 200 is used as a mating surface for cooperating with the mating end, which can directly cooperate with the valve core 200 of the mating end or directly cooperate with the valve seat 100 of the mating end, and the through hole 201 of the valve core 200 directly communicates with the mating end. It can be understood that the mating end can be another connection end, or an interface, a pipe fitting or the like with other structures. Specifically, the outer end surface 230 of the valve core 200 is flush with or protrudes from the outer end surface of the valve seat 100, so as to cooperate with the mating end. It can be understood that one end of the through hole 201 extends to the outer end surface 230 of the valve core 200, that is, the hole formed by the outer end surface 230 of the valve core 200 is used as the interface of the connection end. The first sealing member 300 is arranged between the inner end surface 240 of the valve core 200 and the valve seat 100 to seal the valve core 200 and the valve seat 100. It can be understood that the first sealing member 300 has a relief hole which communicates with the flow channel 110 and the through hole 201 in the state that the flow channel 110 and the through hole 201 are opposite, so as to realize effective sealing while ensuring normal opening or closing of the valve core 200 and the valve seat 100.

[0039] The connecting end provided by the application is used in combination with the counter connecting end. The valve seat 100 is provided with an opening 120, and one end of the valve core 200 is arranged in the opening 120. The valve core 200 can be combined with the counter connecting end, so that the through hole 201 of the valve core 200 is directly communicated with the counter connecting end. Therefore, the outer end of the valve core 200 does not need to be sealed with the valve seat 100, and only the first sealing member 300 needs to be arranged between the inner end surface 240 of the valve core 200 and the valve seat 100. Therefore, the structure is simplified, the resistance of the sealing structure to the movement of the valve core 200 is reduced, the switching operation of the connecting end is more time-saving and labor-saving, the labor intensity of the operator is reduced, and the work efficiency is improved. At the same time, the valve core 200 is directly combined with the counter connecting end, so that the fluid is prevented from flowing along the combined surface between the outer end surface 230 of the valve core 200 and the valve seat 100 and the turbulence caused thereby is avoided, and the problems of energy loss and noise caused by the turbulence are avoided.

[0040] In some embodiments, the valve core 200 is rotatably arranged in the valve seat 100, and the valve seat 100 is provided with a limiting portion for limiting the axial movement of the valve core 200. The valve core 200 is rotatably arranged, and the position relationship between the through hole 201 and the flow channel 110 is switched by rotating the valve core 200. The rotating arrangement space of the valve core 200 is small, and the movement stroke of the valve core 200 required for switching the opening and closing states of the connecting end is small. Therefore, the miniaturization design of the connecting end is facilitated, and the rotating mode of the valve core 200 is also convenient for the arrangement of the sealing member. Specifically, the rotation axis of the valve core 200 is parallel to the axis line of the through hole 201. The limiting portion is arranged to limit the valve core 200 in the valve seat 100 and prevent the valve core 200 from being pulled out. The limiting portion can guide the rotation of the valve core 200, so that the rotation of the valve core 200 is more stable.

[0041] In some embodiments, one end of the valve seat 100 is provided with a mounting groove for mounting the valve core 200, the side wall 131 of the mounting groove is provided with a flange 140, the valve core 200 includes a main body part 210 and a boss 220 protruding from one end of the main body part 210, the limiting part includes the inner end face of the flange 140 and the bottom face 132 of the mounting groove, the inner end face of the flange 140 cooperates with the end face of the main body part 210 provided with the boss 220, and the bottom face 132 of the mounting groove cooperates with the opposite end face of the main body part 210. The side wall 131 of the mounting groove, i.e. its peripheral surface, and the bottom face 132 of the mounting groove, which is an end face connected to the edge of the peripheral surface, cooperate with the inner end face 240 of the valve core 200. It can be understood that the protruding direction of the flange 140 should be towards the side of the valve core 200. Specifically, the flange 140 can protrude radially towards the valve core 200. The flange 140 can be annular to limit the valve core 200 as a whole in the circumferential direction, or the flange 140 can be strip-shaped or block-shaped and multiple flanges 140 can be arranged in the circumferential direction at intervals, so as to limit the valve core 200 in the axial direction from different angles in the circumferential direction. The valve core 200 is arranged with one end protruding, the end face of the main body part 210 provided with the boss 220, i.e. the step face 211 formed between the boss 220 and the main body part 210, cooperates with the inner end face of the flange 140 to limit the position, specifically, the gap cooperation. The other end face of the main body part 210 opposite to the step face 211 cooperates with the bottom face 132 of the mounting groove to limit the position, specifically, the gap cooperation. As described above, the structure is simple and the limiting is reliable.

[0042] Further, the flange 140 surrounds the opening 120, and the boss 220 is arranged in the opening 120. The flange 140 extends from the edge of one end of the valve seat 100 to the valve core 200, and the limiting part is arranged at the edge, which not only limits the position, but also plays a protective role. Specifically, the inner peripheral surface of the flange 140 gap cooperates with the outer peripheral surface of the boss 220.

[0043] In some embodiments, the valve seat 100 comprises a valve seat body 150 and an end cover 160, the valve seat body 150 and the end cover 160 enclose a mounting groove, and the valve core 200 is arranged between the valve seat body 150 and the end cover 160. By arranging the valve seat 100 in a split structure, the assembly of the valve core 200 is facilitated, and the assembly and manufacturing difficulty is reduced. Specifically, the end face of the valve seat body 150 forms the bottom face 132 of the mounting groove, the end cover 160 comprises an outer peripheral portion sleeved on the outer end of the valve seat body 150 and a flange 140 connected with the outer peripheral portion, the main body portion 210 of the valve core 200 is arranged between the flange 140 and the end face of the valve seat body 150, and the boss 220 is arranged in the opening 120 enclosed by the flange 140. Specifically, the end cover 160 and the valve seat body 150 can be detachably connected by screw connection, which is convenient to disassemble and assemble and reliable in connection. Moreover, the screw connection can adjust the distance between the end cover 160 and the valve seat body 150 according to the different thickness of the main body portion 210 of the valve core 200, so that the connection end has better adaptability and can be adapted to valve cores 200 of different specifications.

[0044] In some embodiments, a ball is arranged between the boss 220 and the flange 140. In order to further reduce the resistance of the valve core 200 to rotate, a ball is arranged between the boss 220 and the flange 140, so that even if friction occurs between the boss 220 and the flange 140, the rolling friction force is obviously smaller than the sliding friction force of direct contact between the two, thereby reducing the rotation resistance of the valve core 200. In other embodiments, the friction force between the boss 220 and the flange 140 can also be reduced by means of clearance fit, coating on the mating surface of the boss 220 and the flange 140, etc.

[0045] In some embodiments, one of the outer circumferential surface of the valve core 200 and the inner circumferential surface of the valve seat 100 is provided with a retractable limiting protrusion, and the other is provided with an annular groove matched with the limiting protrusion. The limiting part includes the limiting protrusion or the annular groove provided on the inner circumferential surface of the valve seat 100. In this embodiment, the limiting part includes the limiting protrusion or the annular groove provided on the inner circumferential surface of the valve seat 100, and the outer circumferential surface of the valve core 200 is provided with an annular groove matched with the limiting protrusion on the valve seat 100 or a limiting protrusion matched with the annular groove on the valve seat 100. Taking the case of providing a retractable limiting protrusion on the outer circumferential surface of the valve core 200 and an annular groove on the inner circumferential surface of the valve seat 100, during assembly, the limiting protrusion is retracted due to the action of the inner circumferential surface of the valve seat 100. When the valve core 200 is assembled to the position where the limiting protrusion is opposite to the annular groove, the limiting protrusion can be extended outward to be inserted into the annular groove, so that when the valve core 200 rotates, the limiting protrusion slides along the annular groove to play an axial limiting role. Specifically, a spring is matched with the limiting protrusion, and the spring is used to drive the limiting protrusion to extend outward. In other embodiments, a threaded hole can also be provided on the valve seat 100, and the limiting protrusion is matched with the threaded hole in a threaded manner. The limiting protrusion is screwed in to be inserted into the annular groove or screwed out to exit the annular groove, so as to facilitate the assembly of the valve core 200. In summary, by using the above-mentioned structure, the axial limiting of the valve core 200 is realized, and the valve seat 100 does not need to be provided with a split structure to facilitate the disassembly and assembly of the valve core 200. Specifically, in this embodiment, the flow channel 110 can be connected to the end of the valve seat 100 and serve as an opening 120 matched with the outer end of the valve core 200, that is, the inner circumferential surface of the valve seat 100 can extend in the axial direction.

[0046] In some embodiments, referring to FIGS. 3-4, the outer end surface 230 of the valve core 200 is provided with a sealing groove 202 for mounting a second sealing member 400, and the second sealing member 400 is used for sealing between the valve core 200 and the mating end. In order to facilitate the sealing between the connecting end and the mating end, the sealing groove 202 is provided on the outer end surface 230 of the valve core 200, so that when the valve core 200 is matched with the mating end, the sealing between the two valve cores 200 is realized by providing the second sealing member 400 in the sealing groove 202. Of course, the second sealing member 400 should be provided with a relief hole matched with the through hole 201, so as to realize effective sealing between the two valve cores 200 while not affecting the normal operation of the valve core 200.

[0047] In some embodiments, the first seal 300 comprises a first sealing part 310 and a second sealing part 320. The first sealing part 310 is annular and arranged along the edge of the through hole 201 of the valve core 200 or along the edge of the flow passage 110 of the valve seat 100. The second sealing part 320 is annular and at least partially sleeved outside the first sealing part 310 and arranged in a spaced manner with the first sealing part 310. During the movement of the valve core 200 from the state of communication with the flow passage 110 to the state of misalignment, the flow passage 110 and the through hole 201 are both located within the hollow range of the second sealing part 320. The first sealing part 310 is annular and arranged along the edge of the through hole 201 of the valve core 200 or along the edge of the flow passage 110 of the valve seat 100. It can be understood that the annular shape here is not limited to a circular ring shape, but also includes other shapes that are closed around. The specific shape is arranged correspondingly according to the shape of the through hole 201 when it is arranged on the valve core 200, and is arranged correspondingly according to the shape of the flow passage 110 when it is arranged on the valve seat 100. The second sealing part 320 is annular and at least partially sleeved outside the first sealing part 310 and arranged in a spaced manner with the first sealing part 310. During the movement of the valve core 200 from the state of communication with the flow passage 110 to the state of misalignment, the flow passage 110 and the through hole 201 are both located within the hollow range of the second sealing part 320. Similarly, the shape of the second sealing part 320 can be a circular ring shape or other shapes that are closed around. The second sealing part 320 can be arranged on the valve core 200 or the valve seat 100. When the second sealing part 320 is arranged on the valve core 200, the flow passage 110 is located within the second sealing part 320 within the movement range of the valve core 200. When the second sealing part 320 is arranged on the valve seat 100, the movement track of the through hole 201 is within the hollow range of the second sealing part 320. The forms of the first sealing part 310 and the second sealing part 320 include but are not limited to sealing material rings such as rubber rings and silicone rings. In the state where the valve core 200 is moved to the state of communication between the through hole 201 and the flow passage 110, effective sealing between the valve core 200 and the valve seat 100 can be formed, and fluid is less likely to enter the mating surface between the valve core 200 and the valve seat 100, that is, fluid can flow better along the flow passage 110 and the through hole 201 to form a flow passage, reducing or even eliminating the radial flow of fluid between the mating surfaces, avoiding turbulence caused thereby, and further avoiding problems such as energy loss and noise caused by turbulence. The second sealing part 320 cooperates with the first sealing part 310, and during the movement of the valve core 200 from the state of communication with the flow passage 110 to the state of misalignment, the flow passage 110 and the through hole 201 are both located within the hollow range of the second sealing part 320. Therefore, the second sealing part 320 ensures that the valve core 200 can always be sealed with the valve seat 100 within the movement range.The first seal 300 is arranged as above, which realizes effective sealing between the valve core 200 and the valve seat 100 within the movement range of the valve core 200, reduces the influence of the matching surface on the fluid flow state when the valve core 200 is opened, and has a small contact area between the first seal 300 and the valve core 200 and the valve seat 100, thereby reducing the resistance formed by the movement of the valve core 200, and facilitating the opening or closing operation of the connection end.

[0048] Specifically, the first sealing part 310 and the second sealing part 320 are integrated. Further, part of the first sealing part 310 is formed as part of the second sealing part 320. That is, the first sealing part 310 and the second sealing part 320 share part of each other. The above arrangement facilitates molding and assembly with the connection end, realizes reliable sealing, and greatly reduces the contact area between the seal and the valve core 200 and the valve seat 100.

[0049] In some embodiments, the valve core 200 is rotatably arranged in the valve seat 100, the valve seat 100 is arranged to be connected with the valve seat 100 of another connection end, and the valve seat 100 can rotate relative to the valve seat 100 of another connection end and drive the valve core 200 of another connection end to rotate, so as to simultaneously open or close the two connection ends. Specifically, the valve core 200 is provided with a pushing groove, and the valve seat is provided with a pushing part, the pushing groove is used for inserting the pushing part on another connection end and driving the valve core 200 to move, so as to open or close the flow channel 110.

[0050] In some embodiments, the side wall of the opening 120 is provided with a groove, and the groove and the outer circumferential surface of the valve core 200 form a sliding groove 170, and the pushing part on another connection end can pass through the sliding groove 170 and slide along the sliding groove 170. The pushing groove on the valve core 200 is opposite to the sliding groove 170, so that the pushing part on another connection end can pass through the sliding groove 170 and be inserted into the pushing groove, so as to drive the valve core 200 to move.

[0051] Further, the sliding groove 170 is also used to axially clamp the pushing part on another connection end and the valve seat 100. Specifically, the axial clamping of the sliding groove 170 and the pushing part on another connection end can form a reverse locking structure by cooperation of the pushing part and the sliding groove 170, so as to be axially limited. One end of the sliding groove 170 is larger than the size of the reverse locking structure, so as to facilitate the insertion and extraction of the pushing part. When connected, two hands hold two valve seats 100 respectively, the pushing parts of the valve seats 100 are respectively inserted into the sliding grooves 170 of the corresponding another connection end, the end surfaces of the two valve cores 200 are in contact, and the two hands are rotated in opposite directions. At this time, the pushing parts drive the opposite valve cores 200 to rotate respectively, until the two connection ends are connected at the same time, and the reverse locking structure axially clamps the two valve seats 100. When disconnected, the valve seats are respectively rotated in the opposite direction as above, and when the pushing part is rotated to one end of the sliding groove 170, it can be pulled out of the sliding groove 170.

[0052] In some embodiments, the valve core 200 is provided with a first locking hole 203 and a second locking hole, the valve seat 100 is provided with a mounting hole 120, and the connecting end includes a locking pin 500 movably arranged in the mounting hole 120 in the axial direction. When the valve core 200 is moved to the state of opening the flow channel 110, the locking pin 500 is locked in the first locking hole 203. When the valve core 200 is moved to the state of closing the flow channel 110, the locking pin 500 is locked in the second locking hole. It can be understood that the movement of the locking pin 500 in the axial direction of the valve core 200 includes both the translation of the locking pin 500 in the axial direction and the extension and retraction of the locking pin 500 in the axial direction. By providing the locking pin 500, when the valve core 200 is moved to the open position, that is, the entire flow channel 110 forms a passage, the connecting end is in the open state, and the locking pin 500 is inserted into the first locking hole 203, thereby locking the position of the valve core 200, that is, the valve core 200 cannot continue to rotate relative to the valve seat 100, so that the connecting end can be reliably maintained in the open state. When the valve core 200 is moved to the closed position, the locking pin 500 is inserted into the second locking hole, thereby locking the position of the valve core 200, that is, the valve core 200 cannot continue to move relative to the valve seat 100, so that the connecting end can be reliably maintained in the closed state. In addition, through the cooperation of the locking pin 500 and the first locking hole 203 and the second locking hole, a reminder of the rotating position of the valve core 200 can be provided during the opening or closing operation of the connecting end, such as a sound reminder, a hand feeling reminder caused by different resistances, and the like, and the structure is simple and the positioning is accurate. Moreover, by using one locking pin 500 to cooperate with the first locking hole 203 and the second locking hole, the structure is simple. In the case where the valve core 200 is rotatable relative to the valve seat 100, the first locking hole 203 and the second locking hole can be distributed in the circumferential direction.

[0053] The application also provides a fluid connector. In some embodiments, referring to FIG. 3, the fluid connector includes a male end and a female end, and at least one of the male end and the female end is any one of the connecting ends in the above embodiments. Since the fluid connector uses the connecting end in the above embodiments, the beneficial effects of the fluid connector are described with reference to the above embodiments.

[0054] In some embodiments, the male end and the female end are any one of the connecting ends in the above embodiments, and the male end and the female end are detachably connected in rotation. The male end and the female end can be relatively rotated to communicate or misalign the male end flow-through opening on the end face of the male end with the female end flow-through opening on the end face of the female end. Specifically, when the male end and the female end are relatively rotated, the valve seat 100 of the male end drives the valve core 200 of the female end to rotate, and the valve seat 100 of the female end drives the valve core 200 of the male end to rotate, so as to synchronously open or close the male end and the female end.

[0055] In some embodiments, a second seal 400 is arranged between the outer end face 230 of the male valve core 200 and the outer end face 230 of the female valve core 200. By arranging the second seal 400 between the two valve cores 200, the sealing between the two valve cores 200 is directly achieved.

[0056] The application also provides a fluid connector, which in some embodiments includes a connecting end and a mating end, and each of the connecting end and the mating end includes a valve seat 100 and a valve core 200. The valve seat 100 is internally provided with a flow channel 110, and the valve core 200 is movably arranged in the valve seat 100. The valve core 200 is provided with a through hole 201, and the valve core 200 can be moved to a state in which the through hole 201 communicates with the flow channel 110 and a state in which the through hole 201 is misaligned with the flow channel 110. In a state in which the connecting end and the mating end are docked, the valve core 200 of the connecting end is in contact with the valve core 200 or the valve seat 100 of the mating end, and the flow channel 110 of the connecting end communicates with the flow channel 110 of the mating end. In a state in which the connecting end and the mating end are separated, the connecting end and the mating end are closed respectively. That is, the outer end face 230 of the valve core 200 of the connecting end is used as a mating face for cooperating with the mating end. The outer end face 230 of the valve core 200 of the connecting end can directly cooperate with the valve core 200 of the mating end or directly cooperate with the valve seat 100 of the mating end. The through hole 201 of the outer end face 230 of the valve core 200 of the connecting end directly communicates with the mating end without passing through the flow channel 110 of the valve seat 100 of the connecting end. Specifically, the valve core 200 of the connecting end directly cooperates with the valve core 200 of the mating end, that is, the outer end face 230 of the valve core 200 of the connecting end cooperates with the outer end face 230 of the valve core 200 of the mating end, and the through holes 201 of the two directly communicate. Specifically, the connecting end of the fluid connector can adopt any one of the connecting ends in the above embodiments.

[0057] By using the fluid connector provided by the application, the valve core 200 of the connecting end can directly contact and cooperate with the mating end, so that no sealing is required between the outer end of the valve core 200 and the valve seat 100 of the connecting end, and only a sealing structure needs to be arranged between the inner end face 240 of the valve core 200 and the valve seat 100, thereby simplifying the structure and reducing the resistance of the sealing structure to the movement of the valve core 200, so that the switching operation for opening and closing the connecting end is more time-saving and labor-saving, the labor intensity of the operator is reduced, and the work efficiency is improved.
