[0025] The fluid connector is used for connecting the pipes conveying high-pressure production fluid, so that the two components carrying the corresponding connecting ends of the pipes can move relatively, as a component in a liquid cooling system. The main function is to realize quick on-off of the fluid passage such as pipes and cold plates, facilitate equipment debugging and maintenance, especially in the case of multiple disassembly and assembly and multiple debugging of the equipment.

[0026] In some embodiments, the fluid connector comprises a plug and a socket, wherein one end of the plug is externally connected to a first pipe, the other end of the plug is detachably connected to one end of the socket, and the other end of the socket is externally connected to a second pipe. The plug and the socket are locked by the cooperation of a locking member and a locking catch. The locking member is arranged on the plug, and the locking catch is arranged on the socket; the locking member and the locking catch are cooperatively arranged to fix the plug and the socket.

[0027] The locking member is arranged on the outside of the plug, the locking catch is formed with a transmission-connected locking portion and a control portion, the locking portion penetrates the socket and cooperates with the locking member, and the control portion is arranged at the end of the socket away from the plug to facilitate the locking and unlocking operation of the operator.

[0028] However, during the process of inserting the plug into the socket, the operator needs to hold the plug and the socket respectively, and then insert the plug into the socket. In the related art, the locking member and the locking catch are used for cooperation, the operator holds the side of the socket away from the control portion to reduce the touch of the control portion, so as to complete the disassembly and assembly of the plug and the socket.

[0029] In actual installation process, the activity space between the socket and the plug is small, and it is difficult to hold the part of the plug and the socket away from the control portion, which causes the disassembly and assembly efficiency of the plug and the socket to be low.

[0030] Embodiments of the present disclosure provide a joint assembly. The housing can provide a holding area for the operator, and the separate arrangement of the locking catch and the housing can reduce the occurrence of the displacement of the locking catch caused by the movement of the housing by the operator. Thus, the operator can directly hold the housing, the holding area on the housing can increase the grasping space of the operator, thereby facilitating the operator to hold the socket. Compared with holding the valve seat, the housing is closer to the plug, and the holding area provided by the housing has a larger space, which has the advantages of convenient holding and can reduce the disassembly and assembly time of the plug and the socket, thereby improving the disassembly and assembly efficiency of the plug and the socket.

[0031] As shown in FIGS. 1-2, the embodiment of the present disclosure provides a connector assembly, which comprises a plug 1 and a socket 2. The socket 2 comprises a valve body 21, a locking member 3, a locking piece 22 and a housing 23. The valve body 21 has an insertion cavity 24 for the plug 1 to be inserted in a first direction X1. The locking member 3 is movably arranged on the valve body 21. The locking piece 22 is movably arranged between the valve body 21 and the housing 23, and is used to press against the locking member 3 to lock the plug 1.

[0032] The locking piece 22 is arranged on the outer periphery of the valve body 21, and the housing 23 is arranged on the outer periphery of the valve body 21 and the locking piece 22. The valve body 21 has the insertion cavity 24 for the insertion part 11 to be inserted and connected. The locking piece 22 is used to lock the insertion part 11 located in the insertion cavity 24. The locking piece 22 is arranged separately from the housing 23.

[0033] The plug 1 has an insertion part 11, which is the part of the plug 1 inserted into the socket 2, i.e., the part of the plug 1 inserted into the insertion cavity 24.

[0034] As shown in FIG. 3, the plug 1 can be moved towards the side close to the socket 2 under the driving of a first driving force, and the insertion part 11 is moved towards the side of the insertion cavity 24, so that the plug 1 can abut against the socket 2. The plug 1 can be moved away from the socket 2 under the driving of a second driving force, and the insertion part 11 is moved away from the side of the insertion cavity 24, so that the plug 1 can be separated from the socket 2.

[0035] As shown in FIGS. 3 and 4, the first direction X1 and the second direction X2 are opposite directions, and the vertical first direction Y is arranged perpendicularly to the first direction X1 or the second direction X2.

[0036] As shown in FIGS. 4-5, the locking piece 22 is movably arranged on the valve body 21, and can be moved between a first position and a second position. In the first direction X1, the first position is arranged close to the plug 1, and the second position is arranged close to the socket 2. As shown in FIG. 4, the locking piece 22 is located at the first position. As shown in FIG. 5, the locking piece 22 is located at the second position.

[0037] When the locking piece 22 is located at the first position, the locking piece 22 presses against the locking member 3, and the locking piece 22, the locking member 3 and the valve body 21 are arranged in cooperation to limit the movement between the insertion part 11 and the insertion cavity 24, so as to realize the locking between the plug 1 and the socket 2. When the locking piece 22 is located at the second position, the locking piece 22 is separated from the insertion part 11 located in the insertion cavity 24, so as to realize the locking between the insertion part 11 and the insertion cavity 24. When the locking piece 22 is located at the second position, the locking piece 22 is separated from the insertion part 11 located in the insertion cavity 24, so as to realize the locking between the insertion part 11 and the insertion cavity 24.

[0038] The second position is located on the side opposite to the first position, away from plug 1.

[0039] The outer casing 23 is disposed on the side of the locking member 22 away from the valve body 21. The outer casing 23 is used to protect the locking member 22. A gripping part 233 is formed on the side of the outer casing 23 away from the locking member 22. The gripping part 233 is used to provide a gripping area.

[0040] The grip 233 has a variety of different configurations. The following is an example of how the grip 233 can be configured.

[0041] As shown in Figure 10, in some embodiments, the grip portion 233 may be an anti-slip outer wall, which is sleeved on the end of the housing 23 away from the valve body 21, and the anti-slip outer wall is used to provide a gripping area for the operator.

[0042] In some embodiments, the gripping part 233 may be a gripper groove, which is formed at the end of the housing 23 away from the valve body 21, and the gripper groove is used to provide a gripping area for the robot arm.

[0043] The specific arrangement of the grip 233 is not limited and can be selected according to actual usage requirements. It is only necessary to ensure that the grip 233 is located on the side of the housing 23 away from the valve body 21.

[0044] The operator holds the outer casing 23 with one hand and the plug 1 with the other. The plug 1 moves towards the side closer to the socket 2 under the operator's grip, so that the insertion part 11 can move towards the first direction X1 to enter the insertion cavity 24. The locking member 22 and the locking member 3 cooperate to lock the insertion part 11 located in the insertion cavity 24.

[0045] One operator grips the outer casing 23, and the other operator grips the plug 1. The plug 1 moves toward the side closer to the socket 2 under the grip of the operator, so that the insertion part 11 can move toward the first direction X1 to enter the insertion cavity 24. The locking member 22 and the locking member 3 cooperate to lock the insertion part 11 located in the insertion cavity 24.

[0046] The outer casing 23 provides a gripping area for the socket 2, facilitating gripping by operators or robotic arms, offering advantages such as ease of operation and low disassembly costs. Therefore, the embodiments of this disclosure can solve the problems of difficult insertion and installation of the socket 2 and plug 1, and low efficiency in disassembly and assembly.

[0047] When the locking element 22 can move between the first position and the second position, there are a variety of different ways of moving between the locking element 22 and the valve body 21. The following are examples of the ways of moving between the locking element 22 and the valve body 21.

[0048] In some embodiments, in the first direction X1, the second position is located on the side of the first position away from the plug 1, and the first position and the second position are connected in a straight line, that is, the locking piece 22 is movably arranged on the valve body 21.

[0049] In some embodiments, in the first direction X1, the second position is located on the side of the first position away from the plug 1, and the first position and the second position are connected in a spiral line, that is, the locking piece 22 is movably arranged on the valve body 21, and the locking piece 22 is rotatably arranged relative to the valve body 21.

[0050] The movement mode between the locking piece 22 and the valve body 21 is not limited, and can be selected according to actual use requirements, as long as the locking piece 22 is movably arranged on the valve body 21.

[0051] When the plug 1 is installed with the socket 2, the shell 23 moves towards the first direction X1 under the action of the first external force, and drives the locking piece 22 to lock the insertion part 11 located in the insertion cavity 24; when the plug 1 is disassembled with the socket 2, the shell 23 moves in the second direction X2 under the action of the second external force, so that the locking piece 22 is disengaged from the locking of the insertion part 11.

[0052] When the plug 1 is installed with the socket 2, the shell 23 can be driven to move towards the side close to the plug 1 under the action of the first external force, and drive the locking piece 22 to lock the insertion part 11 located in the insertion cavity 24, to limit the movement of the insertion part 11 in the insertion cavity 24 relative to the insertion cavity 24, so as to install the plug 1 to the socket 2, which has the advantage of simple installation.

[0053] When the shell 23 can be driven to move towards the side close to the plug 1 under the action of the first external force, the plug 1 can abut against the socket 2.

[0054] When the plug 1 is disassembled with the socket 2, the shell 23 can be driven to move in the second direction X2 under the action of the second external force, and drive the locking piece 22 and the locking piece 3 to disengage from the locking of the insertion part 11, so as to release the movement between the insertion part 11 in the insertion cavity 24 and the insertion cavity 24, thereby facilitating the disengagement of the plug 1 from the socket 2, which has the advantage of convenient disassembly.

[0055] The shell 23 and the locking piece 22 are movably connected.

[0056] The movable connection between the shell 23 and the locking piece 22 can reduce the occurrence of the shell 23 moving transmission causing the locking piece 22 to deviate, thereby reducing the locking difficulty of the locking piece 22 locking the insertion part 11 located in the insertion cavity 24.

[0057] The shell 23 and the locking piece 22 have a plurality of different arrangement modes, and the arrangement mode between the shell 23 and the locking piece 22 will be exemplified below.

[0058] In some embodiments, the shell 23 is located on the side of the locking piece 22 away from the valve body 21, and the shell 23 and the locking piece 22 are spaced apart in the direction from the plug 1 to the socket 2.

[0059] In some embodiments, the shell 23 is located on the side of the locking piece 22 away from the valve body 21, and the shell 23 and the locking piece 22 are spaced apart in the direction from the plug 1 to the socket 2.

[0060] The arrangement between the shell 23 and the locking piece 22 is not limited, and can be selected according to actual use requirements.

[0061] The shell 23 has various different setting shapes, and the setting shapes of the shell 23 are exemplarily described below.

[0062] In an embodiment, the shell 23 can be a protective sleeve, the protective sleeve is sleeved on the outer ring of the valve body 21, and the locking piece 22 is arranged between the protective sleeve and the valve body 21. The protective sleeve is used for protecting the locking piece 22 arranged between the protective sleeve and the valve body 21, and in the case that an operator holds the protective sleeve, the interference of the protective sleeve on the locking piece 22 is reduced, so that the locking piece 22 can work normally, thereby improving the disassembly efficiency between the plug 1 and the socket 2.

[0063] In some embodiments, the shell 23 can be a mounting plate, the mounting plate is arranged on the valve body 21, and the mounting plate and the valve body 21 are spaced apart in the first direction Y; the locking piece 22 and the mounting plate are arranged separately; the mounting plate is used for providing a holding space for an operator, thereby increasing the holding area of the operator, and the mounting plate and the locking piece 22 are arranged separately, so that in the case that the operator holds the mounting plate, the interference of the mounting plate on the locking piece 22 is reduced, so that the locking piece 22 can work normally, thereby improving the disassembly efficiency between the plug 1 and the socket 2.

[0064] The specific arrangement of the shell 23 is not limited, and can be selected according to actual use requirements.

[0065] The shell 23 and the valve body 21 form the movable cavity 25, and the locking piece 22 is movably connected in the movable cavity 25.

[0066] The movable cavity 25 is used for accommodating and protecting the locking piece 22. The locking piece 22 is arranged in the movable cavity 25, and the movable cavity 25 can accommodate the locking piece to reduce the occurrence of the locking piece 22 moving under the driving of the shell 23 due to the deviation of the shell 23, and can reduce the occurrence of the locking between the plug 1 and the socket 2 being released due to the direct contact between the external components and the locking piece 22, thereby improving the connection stability between the plug 1 and the socket 2.

[0067] As shown in FIG. 6, the embodiment of the present disclosure provides that the locking piece 3 is arranged on the valve body 21, and at least part of the locking piece 3 is used for abutting against the locking piece 22 to be locked in the insertion cavity 24 under the pressing force of the locking piece 22.

[0069] The connector assembly provided by the embodiment of the present disclosure further comprises a first driving piece 4 arranged on the valve body 21 and abutting against the locking piece 22, so that the locking piece 22 has a moving tendency towards the second direction X2.

[0070] The moving tendency means that the locking piece 22 does not actually move, but has a potential moving tendency towards the second direction X2 due to the driving force of the first driving piece 4.

[0071] The first driving piece 4 has various different arrangement modes, and the specific arrangement modes of the first driving piece 4 are exemplified below.

[0072] In some embodiments, the first driving piece 4 is a first spring, one end of the first spring abuts against the locking piece 22, and the other end of the first spring abuts against the valve body 21, and the first spring can drive the locking piece 22 to move towards the second direction X2 to abut against the locking piece 3.

[0073] In some embodiments, the first driving piece 4 is a first air pump, the first air pump is formed with a first mounting part and a first output part, the first mounting part is mounted on the valve body 21, and the first output part is drivingly connected to the locking piece 22, and the first air pump can drive the locking piece 22 to move towards the second direction X2 under the action of the driving force of the first air pump to abut against the locking piece 3.

[0074] The specific arrangement mode of the first driving piece 4 is not limited, and can be selected according to actual use requirements, as long as the first driving piece 4 can drive the locking piece 22 to move towards the side close to the locking piece 3.

[0075] The first driving piece 4 can drive the locking piece 22 to move towards the second direction X2 to abut against the locking piece 3, so as to reduce the locking difficulty between the locking piece 22 and the locking piece 3.
