Description

Fluid connector socket and fluid connector assembly

Technical Field

The invention belongs to the field of fluid connectors, and particularly relates to a fluid connector socket and a fluid connector assembly.

Background

With the rapid development of services such as 5G, edge computing, cloud computing, AI artificial intelligence and the like, the traditional air-cooling heat dissipation technology is more and more unprecedented in increasing heat flux density in a data center. The liquid cooling heat dissipation technology is the first choice for heat dissipation of high-power and high-heat-flux electronic equipment in a data center because of the characteristics of high heat dissipation efficiency, strong heat dissipation capability, low noise, compact structure, energy conservation, consumption reduction and the like.

The liquid cooling architecture of the existing cold plate type liquid cooling server comprises two types of manual insertion and blind insertion. The liquid cooling loop of the hand-plug type framework is plugged by machine room operation and maintenance personnel; the blind-plug architecture realizes automatic connection and disconnection of liquid between the server rack and the cabinet through the fluid connector module. The blind-plug architecture can realize automatic operation, is convenient to operate, and meets the requirements of automatic inspection and robot operation and maintenance in the future; therefore, the architecture is likely to become a mainstream liquid cooling architecture of future data center servers.

Server racks are currently mounted in cabinets by push-pull type like drawers. The structure is easy to cause engineering errors and accumulated dimensional tolerance, so that the position accuracy of the rack in the cabinet is not easy to control, and further, the fluid connector between the rack and the cabinet is easy to generate dislocation when blind insertion is performed. In order to overcome such a drawback, most of the existing fluid connectors have a multi-degree-of-freedom floating function to compensate for engineering errors and dimensional tolerance accumulation, so as to ensure that the fluid connectors between the server rack and the cabinet can be smoothly plugged.

The utility model of CN215870015U, for example, discloses a floating liquid-cooled connector socket, which comprises a mounting housing and a connector mounting plate. The connector mounting plate is floatingly mounted on the mounting housing by a plurality of springs; the fluid connector is fixedly mounted on the connector mounting plate and floats with the connector mounting plate. The structure is used for installing the fluid connector through the connector mounting plate, realizing floating adjustment through the spring group connected between the connector mounting plate and the mounting shell, and has complex structure, larger occupied space and inconvenient application on a small-sized or low-height server.

Disclosure of Invention

The utility model aims to provide a fluid connector socket so as to solve the technical problems of complex structure and large occupied space of the existing fluid connector; the utility model also aims to provide a fluid connector assembly to solve the technical problems of complex structure and large occupied space of the existing fluid connector assembly.

The utility model adopts the following technical scheme:

the fluid connector socket comprises a socket connector and a mounting frame, wherein the socket connector comprises a main body and a mounting end positioned at one plugging side opposite to the main body, a fixed connection structure for being directly and fixedly connected to a device body is arranged on the mounting frame, a mounting hole is further formed in the mounting frame, and the mounting end of the socket connector is inserted into the mounting hole; the installation hole and the installation end of the socket connector are provided with a radial floating gap and a floating maintaining structure, and the floating maintaining structure suspends and maintains the installation end of the socket connector in the installation hole and can generate adaptive elastic deformation when the installation end of the socket connector is acted by external force so as to realize floatable adjustment of the installation end of the socket connector in the installation hole.

The beneficial effects are that: the invention improves on the prior fluid connector socket, and the mounting end of the socket connector is suspended and held in the mounting hole by directly arranging the mounting hole on the mounting frame, arranging a radial floating gap between the mounting hole and the mounting end of the socket connector and a floating holding structure. When the fluid connector socket and the matched fluid connector plug are in blind insertion, the mounting end of the socket connector is acted by external force during blind insertion, and then adaptive floating displacement or deflection occurs in the mounting hole. By adopting the arrangement, the fluid connector socket can be directly arranged on the equipment body through the mounting seat and the fixed connection structure on the mounting seat, and floating maintenance is realized through the floating maintenance structure arranged in the mounting hole of the mounting seat, so that the structure of the existing fluid connector socket is effectively simplified, and the occupied space is reduced.

Further: the floating maintaining structure comprises a first elastic piece and an anti-falling structure; the first elastic piece comprises an inner acting end matched with the mounting end of the socket connector and an outer acting end matched with the wall of the mounting hole, and can elastically deform to realize floating adjustment when the mounting end of the socket connector moves in the radial direction and/or deflects relative to the axial direction in the mounting hole; the anti-falling structure is arranged on the mounting end and positioned on two sides of the first elastic piece and used for keeping the mounting ends of the first elastic piece and the socket connector in the mounting hole.

The beneficial effects are that: by adopting the scheme, the floating retaining effect on the socket connector can be realized through the first elastic piece. Compared with the prior art, the floating maintaining structure is effectively simplified, and the occupied space of the fluid connector socket is prevented from being increased due to the fact that the structure is complex.

Further: the first elastic piece is a spherical spring, the inner walls of the closing-in sections at the two ends of the spherical spring are used as inner acting ends to be in contact connection with the mounting end of the socket connector, and the outer surface of the middle large-diameter section is used as an outer acting end to be in contact connection with the wall of the mounting hole; the mounting end of the socket connector is inserted into the ball spring and held by the ball spring at the center of the mounting hole so as to achieve a floating adjustment of the mounting end of the socket connector in the mounting hole in radial movement and/or relative to axial runout.

The beneficial effects are that: because of the self construction reason, the closing sections at the two ends of the spherical spring can realize the same-direction displacement relative to the middle large-diameter section, so the spherical spring is adopted as a first elastic piece, the outer wall of the large-diameter section of the spherical spring is propped against the wall of the mounting hole, and the mounting ends of the socket connectors which are conveniently inserted into the spherical spring and are contacted with the inner walls of the closing sections at the two ends of the spherical spring can realize the floating adjustment along the radial direction or relative to the axial deflection in the mounting hole. Meanwhile, the spherical spring has no compression condition in the radial direction, so that the same-direction displacement of the closing-in sections at the two ends relative to the middle large-diameter section is close to a radial floating gap between the mounting hole and the mounting end of the socket connector. Therefore, the space in the mounting hole can be effectively utilized, and the problem of the increase of the volume of the socket connector caused by the waste of the space is avoided. Meanwhile, the structure is simple, and the implementation is easy.

Further: the anti-falling structure comprises a stop surface arranged on the socket connector and a stop structure arranged at one end of the installation end of the socket connector far away from the main body, wherein the stop structure is matched with the outer edge of one side of the installation hole far away from the main body in a stop manner so as to realize the anti-falling effect.

The beneficial effects are that: by adopting the structure, the retaining surface structure of the socket connector can be utilized to realize the anti-falling effect along the direction deviating from the main body, so that the anti-falling structure is effectively simplified, and the occupied space of the socket of the fluid connector is further effectively saved.

Further: an axial distance exists between the blocking surface and the hole edge of the mounting hole so as to form a deflection gap for axially deflecting the socket connector relative to the mounting hole.

The beneficial effects are that: by adopting the scheme, the axial deflection of the socket connector relative to the mounting hole can be conveniently realized through the axial distance. The stop surface is biased as the receptacle connector mounting end is deflected axially within the mounting bore. The axial spacing between the stop surface and the hole edge of the mounting hole may provide the required space for the stop surface to deflect.

Further: a second elastic piece is arranged in the axial space; the second elastic piece is used for keeping the socket connector at the position axially concentric with the mounting hole and promoting the socket connector to reset after the socket connector deflects axially relative to the mounting hole due to stress; the anti-slip structure clamps the second elastic member in the axial spacing.

The beneficial effects are that: by adopting the scheme, the socket connector can be kept at the position concentric with the axial direction of the mounting hole through the second elastic piece, and the effect of causing the socket connector to reset after the socket connector deflects axially relative to the mounting hole due to stress is realized, so that the next blind insertion is greatly facilitated.

Further: the second elastic piece is a wave spring or a rubber piece.

The beneficial effects are that: the wave spring and the rubber piece have simple structures and small occupied space. By adopting the scheme, the space occupied by the second elastic piece can be reduced, and the occupied space of the fluid connector socket is further reduced.

Further: the mounting frame is an L-shaped plate, and the mounting hole is formed in one side wall of the L-shaped plate; the mounting hole extends to a cylindrical outer edge on a hole edge on one side of the main body, which is away from the socket connector.

The beneficial effects are that: by adopting the scheme, one side of the mounting hole, which is away from the socket connector main body, is provided with a larger space, and the mounting requirement of the socket connector is met on the basis that the occupied space of the fluid connector socket is not increased.

Further: a floating guide frame is also arranged between the socket connector and the mounting frame; the floating guide frame is provided with a guide structure matched with the guide structure on the plug of the adaptive fluid connector so as to force the socket connector to carry out adaptive floating displacement and/or deflection through the guide structure in the blind insertion process, thereby being convenient for the plug of the adaptive fluid connector to be inserted.

The beneficial effects are that: by adopting the scheme, the socket connector can be forced to carry out adaptive floating displacement and/or deflection through the guide structure, so that the plug of the adaptive fluid connector can be conveniently inserted.

A fluid connector assembly comprising a fluid connector receptacle and a fluid connector plug adapted to couple with the fluid connector receptacle; the fluid connector socket comprises a socket connector and a mounting frame, wherein the socket connector comprises a main body and a mounting end positioned at one plugging side opposite to the main body, a fixed connection structure for being directly and fixedly connected to a device body is arranged on the mounting frame, a mounting hole is further formed in the mounting frame, and the mounting end of the socket connector is inserted into the mounting hole; the installation hole and the installation end of the socket connector are provided with a radial floating gap and a floating maintaining structure, and the floating maintaining structure suspends and maintains the installation end of the socket connector in the installation hole and can generate adaptive elastic deformation when the installation end of the socket connector is acted by external force so as to realize floatable adjustment of the installation end of the socket connector in the installation hole.

The beneficial effects are that: the invention improves on the prior fluid connector assembly, and the mounting end of the socket connector of the fluid connector socket can be suspended and held in the mounting hole by directly arranging the mounting hole on the mounting frame of the fluid connector socket, arranging a radial floating gap between the mounting hole and the mounting end of the socket connector and a floating holding structure. When the fluid connector socket and the fluid connector plug are in blind insertion, the mounting end of the socket connector is acted by external force of the blind insertion, and then adaptive floating displacement occurs in the mounting hole so as to meet the position of the fluid connector plug to complete insertion. By adopting the arrangement, the fluid connector socket can be directly arranged on the equipment body through the mounting seat and the fixed connection structure on the mounting seat, and floating maintenance is realized through the floating maintenance structure arranged in the mounting hole of the mounting seat, so that the structure of the existing fluid connector socket is effectively simplified, and the occupied space is reduced.

Detailed Description

The features and capabilities of the present invention are described in further detail below in connection with the examples.

Example 1 of a fluid connector assembly in the present invention:

for the sake of clarity of the structure of this embodiment, the up-down direction of fig. 5 is hereinafter referred to as the up-down direction of the fluid connector assembly, the left-right direction of fig. 5 is referred to as the left-right direction of the fluid connector assembly, and the other two directions of fig. 5 are referred to as the front-rear direction of the fluid connector assembly, which do not represent the actual orientation of the product.

A fluid connector receptacle 1 as shown in fig. 1 and 2 is configured to be inserted into and coupled with a fluid connector plug 2 as shown in fig. 3 to form a fluid connector assembly according to the present invention. Wherein the fluid connector plug 2 comprises a pair of plug connectors 3 and plug bases 4 that mate with receptacle connectors 5 on the fluid connector receptacle 1. The plug connector 3 is fixed to the plug base and has one end overhanging the plug base for coupling with the fluid connector socket 1.

As shown in fig. 4 and 5, the fluid connector socket 1 includes a socket connector 5 and a mounting bracket 6. The receptacle connector 5 comprises a body 7 and a mounting end 8 at a mating side facing away from the body 7. The foregoing is related to the prior art and is therefore not repeated. In comparison with the prior art, the key of this embodiment is that the mounting bracket 6 is directly provided with the mounting hole 9 for mounting the mounting end 8. The mounting end 8 of the receptacle connector 5 is directly inserted into the mounting hole 9 and has an outer diameter smaller than the aperture of the mounting hole 9 such that a radial floating gap 10 exists between the mounting hole 9 and the outer surface of the mounting end 8. A floating retention structure is provided in the floating gap to float and retain the mounting end 8 of the receptacle connector 5 within the mounting hole 9.

The mounting frame is also provided with a through hole 19 as a fixed connection structure. Fasteners are inserted through the holes 19 to facilitate secure attachment of the mounting bracket to the equipment substrate. It is conceivable that the fixed connection may also be a welded structure provided on the mounting frame, in order to fixedly connect the mounting frame to the device base body by means of welding.

As shown in fig. 6 and 7, when the socket connector 5 is subjected to an external force to cause the mounting end 8 to radially displace or deflect relative to the axial direction in the mounting hole 9, the floating holding structure is forced to elastically deform and provide a restoring reaction force to the mounting end 8, so as to realize floatable adjustment of the mounting end 8 in the mounting hole 9. By adopting the arrangement, the fluid connector socket can be directly arranged on the equipment body through the mounting seat and the fixed connection structure on the mounting seat, and floating maintenance is realized through the floating maintenance structure arranged in the mounting hole of the mounting seat, so that the structure of the existing fluid connector socket is effectively simplified, and the occupied space is reduced. On the basis, the structure and the occupied space of the fluid connector assembly are reduced, the fluid connector assembly is more suitable for small equipment bodies, and the universality of the fluid connector assembly is effectively improved.

When in use, the fluid connector socket 1 is fixed on equipment needing liquid cooling, and the socket connector 5 is communicated with a liquid cooling loop of the equipment; the fluid connector plug 2 is communicated with an external liquid supply pipeline. The fluid connector plug 2 and the fluid connector socket 1 are mutually inserted and combined, so that the plug connector 3 and the socket connector 5 are mutually coupled, and the liquid cooling loop of the equipment and a liquid supply pipeline of the peripheral equipment are further communicated. When the fluid connector plug 2 and the fluid connector socket 1 are inserted into each other in a blind manner, the fluid connector plug 2 applies an external force to the socket connector 5 on the fluid connector socket 1 in the aligning process, so that the socket connector 5 is forced to adaptively displace in the mounting hole 9 on the mounting frame 6 to match the position of the plug connector 3 on the fluid connector plug 2 to achieve insertion. When the fluid connector plug 2 is separated from the fluid connector receptacle 1, the receptacle connector 5 is reset to the center of the mounting hole 9 for the next blind insertion.

It should be emphasized that the fluid connector assembly may also be in communication with an external fluid supply line and the plug is in communication with the liquid cooling circuit of the apparatus. The plug and the fluid connector component are mutually inserted, so that the floating end of the connector and the fixed end of the connector are mutually coupled to communicate the liquid cooling loop of the equipment with the liquid supply pipeline of the external equipment.

Example 2 of the fluid connector assembly of the present invention:

a fluid connector assembly includes a fluid connector receptacle and a fluid connector plug. The specific structure of the fluid connector socket can be referred to the fluid connector socket 1 shown in fig. 1, 2, 4 and 5; for a specific structure of the fluid connector plug, reference may be made to the fluid connector plug 2 shown in fig. 3. Wherein the fluid connector plug 2 comprises a pair of plug connectors 3 and plug bases 4 that mate with receptacle connectors 5 on the fluid connector receptacle 1. The plug connector 3 is fixed to the plug base and has one end overhanging the plug base so as to be coupled with the receptacle connector 5.

The fluid connector receptacle 1 comprises a receptacle connector 5 and a mounting frame 6. The receptacle connector 5 comprises a body 7 and a mounting end 8 at a mating side facing away from the body 7. The mounting frame 6 is directly provided with a mounting hole 9 for mounting the mounting end 8 and a through hole 19 for fixedly connecting the mounting frame and the equipment body. The mounting end 8 of the receptacle connector 5 is directly inserted into the mounting hole 9 and has an outer diameter smaller than the aperture of the mounting hole 9 such that a radial floating gap 10 exists between the mounting hole 9 and the outer surface of the mounting end 8. A floating retention structure is provided in the floating gap to float and retain the mounting end 8 of the receptacle connector 5 within the mounting hole 9. When the socket connector 5 is subjected to external force to cause the mounting end 8 to radially displace and/or deflect relative to the axial direction in the mounting hole 9, the floating holding structure is forced to elastically deform and provide a restoring reaction force to the mounting end 8, so that the floatable adjustment of the mounting end 8 in the mounting hole 9 is realized. A graphical illustration of the radial displacement of the mounting end 8 within the mounting bore 9 may be seen in fig. 6; an illustration of the relative axial deflection of the mounting end 8 within the mounting bore 9 can be seen in fig. 7.

The key of this embodiment is that the floating holding structure includes a first elastic member and an anti-falling structure. Wherein the first elastic member comprises an inner active end connected with the mounting end 8 and an outer active end connected with the wall of the mounting hole 9. The inner and outer active ends may be displaced from each other when the first elastic member is elastically deformed. By means of the relative displacement between the inner and outer active ends of the first elastic element itself, a floating adjustment of the mounting end 8 in the mounting hole 9 in radial movement or relative to axial deflection can be facilitated. The anti-falling structure is arranged on the mounting end 8 and positioned on two sides of the first elastic piece so as to keep the first elastic piece and the mounting end 8 in the mounting hole 9. Compared with the prior art, the floating holding function of the socket connector 5 through the first elastic piece can effectively simplify the floating holding structure, and the occupied space of the fluid connector socket 1 is prevented from being increased due to the complex structure.

In addition, it is also conceivable that the first spring element in the floating holding means can be replaced by a spring element group. The elastic piece group is connected with the mounting end 8 and the wall of the mounting hole 9 in a fixed connection mode so as to replace the anti-falling structure to keep the first elastic piece and the mounting end 8 in the mounting hole 9. Wherein the part of the elastic member group connected with the mounting end 8 is used as an inner acting end, and the part connected with the wall of the mounting hole 9 is used as an outer acting end.

Example 3 of fluid connector assembly in the present invention:

The fluid connector receptacle 1 comprises a receptacle connector 5 and a mounting frame 6. The receptacle connector 5 comprises a body 7 and a mounting end 8 at a mating side facing away from the body 7. The mounting frame 6 is directly provided with a mounting hole 9 for mounting the mounting end 8 and a through hole 19 for fixedly connecting the mounting frame and the equipment body. The mounting end 8 of the receptacle connector 5 is directly inserted into the mounting hole 9 and has an outer diameter smaller than the aperture of the mounting hole 9 such that a radial floating gap 10 exists between the mounting hole 9 and the outer surface of the mounting end 8. A floating retention structure is provided in the floating gap to float and retain the mounting end 8 of the receptacle connector 5 within the mounting hole 9. The floating maintaining structure comprises a first elastic piece and an anti-falling structure. The anti-disengaging structure is arranged on the mounting end 8 and located on both sides of the first elastic member so as to keep the mounting end 8 of the first elastic member and the socket connector 5 in the mounting hole 9. When the socket connector 5 is subjected to external force to cause the mounting end 8 to radially displace and/or deflect relative to the axial direction in the mounting hole 9, the floating holding structure is forced to elastically deform and provide a restoring reaction force to the mounting end 8, so that the floatable adjustment of the mounting end 8 in the mounting hole 9 is realized. A graphical illustration of the radial displacement of the mounting end 8 within the mounting bore 9 may be seen in fig. 6; an illustration of the relative axial deflection of the mounting end 8 within the mounting bore 9 can be seen in fig. 7.

The key point of this embodiment is that the aforementioned first elastic member is specifically a ball spring 11. The inner walls of the closing-in sections at the two ends of the spherical spring 11 are used as inner acting ends to be contacted and connected with the mounting end 8 of the socket connector 5, and the outer surface of the middle large-diameter section is used as outer acting ends to be contacted and connected with the wall of the mounting hole 9. The mounting end 8 is inserted into the ball spring 11 and is held at the center of the mounting hole 9 by the ball spring 11. As shown in fig. 6, when the mounting end 8 is radially displaced in the mounting hole 9 under the action of an external force, the outer surface of the middle large-diameter section of the spherical spring 11 abuts against the wall of the mounting hole 9, and the closing sections at the two ends approach the wall of the hole along the direction of the external force, so that floating adjustment of radial movement of the mounting end 8 in the mounting hole 9 is realized. As shown in fig. 7, when the installation end 8 is subjected to external force and has deflection relative to the axial direction in the installation hole 9, the outer surface of the middle large-diameter section of the spherical spring 11 is abutted against the wall of the installation hole 9, one end closing-in section is close to the wall of the hole along the direction of the external force, and the other end closing-in section is close to the wall of the other side along the direction deviating from the direction of the external force, so that floating adjustment of the installation end 8 relative to the axial deflection in the installation hole 9 is realized.

The spherical spring 11 is convenient to be inserted into the spherical spring 11 due to the above construction, and the mounting ends 8 which are contacted with the inner walls of the closing sections at the two ends of the spherical spring 11 realize floating adjustment in the mounting holes 9 along radial movement or relative to axial deflection. At the same time, the ball spring 11 is not compressed in the radial direction, so that the same displacement of the two end closing-in sections relative to the middle large-diameter section approaches the radial floating gap 10 between the mounting hole 9 and the mounting end 8 of the socket connector 5. This makes it possible to effectively use the space in the mounting hole 9 and to avoid the problem of an increase in the volume of the receptacle connector 5 due to the waste of space.

Based on the above, it is easily conceivable that the aforementioned spherical spring 11 may be replaced by a pair of oppositely arranged conical springs or scroll springs, and the anti-drop structure is adapted according to the specific selected elastic member.

When the first elastic piece is a conical spring, the inner wall of the closing-in section of the conical spring is used as an inner acting end to be in contact connection with the mounting end 8 of the socket connector 5, and the outer surface of the large-diameter section is used as an outer acting end to be in contact connection with the wall of the mounting hole 9. The large diameter sections are arranged oppositely between the paired conical springs, and the closing sections are arranged oppositely. When the mounting end 8 is radially displaced in the mounting hole 9 under the action of external force, the outer surface of the middle large-diameter section of the conical spring is abutted against the wall of the mounting hole 9, and the closing sections at the two ends are close to the wall of the hole along the direction of the external force, so that floating adjustment of the radial movement of the mounting end 8 in the mounting hole 9 is realized. When the mounting end 8 is subjected to external force and has deflection relative to the axial direction in the mounting hole 9, the outer surface of the middle large-diameter section of the conical spring is abutted against the wall of the mounting hole 9, and the closing-in section is close to the wall of the hole along the direction of the external force, so that floating adjustment of the mounting end 8 relative to the axial deflection in the mounting hole 9 is realized.

When the first elastic piece is a volute spring, the inner wall at the volute spring volute core is used as an inner acting end to be in contact connection with the mounting end 8 of the socket connector 5, and the outer surface of the volute spring is used as an outer acting end to be in contact connection with the wall of the mounting hole 9. The pair of volute springs are arranged opposite to each other. When the mounting end 8 is radially displaced in the mounting hole 9 under the action of external force, the outer surface of the volute spring is abutted against the wall of the mounting hole 9, and the volute center is close to the wall of the hole along the direction of the external force, so that floating adjustment of the radial movement of the mounting end 8 in the mounting hole 9 is realized. When the mounting end 8 is subjected to external force and has deflection relative to the axial direction in the mounting hole 9, the outer ring of the volute spring is kept in the mounting hole 9 under the action of the anti-drop structure, and the volute core deflects relative to the axial direction of the mounting hole 9 along the direction of the external force, so that the floating adjustment of the mounting end 8 relative to the axial deflection in the mounting hole 9 is realized.

Example 4 of fluid connector assembly in the present invention:

The key of this embodiment is that the receptacle connector 5 is provided with a stop surface 13. The end of the mounting end 8 remote from the body 7 is provided with a stop structure. The anti-drop structure comprises the stop surface 13 and the stop structure. Wherein the stop surface 13 is in stop engagement with the mounting hole 9 hole opposite thereto to prevent the receptacle connector 5 from being disengaged from the mounting hole 9 in a direction away from the main body 7; the stop structure engages with the hole of the mounting hole 9 opposite thereto along the stop to prevent the receptacle connector 5 from coming out of the mounting hole 9 in a direction toward the main body 7. The stop surface 13 and the stop structure also retain the first resilient element in position therebetween to prevent the first resilient element from being removed from the mounting hole 9.

The anti-falling effect of the socket connector 5 along the direction deviating from the main body 7 is realized by utilizing the self blocking surface 13 structure of the socket connector, so that the anti-falling structure can be effectively simplified, and the occupied space of the fluid connector socket 1 is effectively saved.

It is conceivable in this embodiment that an outward collar or a collar can be provided at the transition between the socket connector 5 and the mounting end 8. The collar or collar has an outer diameter greater than the outer diameter of the mounting hole 9 to provide a stop surface and a corresponding outer edge stop fit with the mounting hole 9.

The blocking structure in this embodiment may be a blocking cover 14 and a circlip 15 as shown in fig. 2. The outer diameter of the blocking cover 14 is larger than the aperture of the mounting hole 9 so as to be convenient for blocking and matching on the corresponding outer edge of the mounting hole 9. The center of the blocking cover 14 is provided with an avoidance hole so that the mounting end 8 of the socket connector 5 extends out of the avoidance hole. The part of the mounting end 8 outside the avoidance hole is provided with a check ring groove, and an elastic check ring 15 is arranged in the check ring groove. The outer diameter of the circlip 15 is larger than the diameter of the avoidance hole so as to be matched with the hole edge of the avoidance hole in a blocking way, and then the blocking surface 13 is matched to keep the blocking cover 14 at a position matched with the hole edge of the mounting hole 9 in a blocking way. Furthermore, the blocking cover 14 can also be fixedly connected with the mounting end 8 in a threaded pair fit, interference connection and the like, so that the blocking cover can be directly matched with the blocking surface 13 to realize the blocking effect without arranging the elastic retainer ring 15 to keep the blocking cover at a position matched with the hole of the mounting hole 9 along the blocking.

Example 5 of a fluid connector assembly in the present invention:

The key of this embodiment is that an axial distance 16 exists between the stop surface 13 and the hole edge of the mounting hole 9 to form a deflection gap for deflecting the receptacle connector 5 relative to the mounting hole 9. The stop surface 13 will deflect as the mounting end 8 deflects axially relative to the mounting bore 9. The axial spacing 16 between the stop face 13 and the hole edge of the mounting hole 9 may provide the required space for deflection of the stop face 13. It is of course conceivable that in other embodiments, such as in certain situations where a yaw float adjustment is not required, the stop surface 13 may also be directly abutted against the hole edge of the mounting hole 9, only a float adjustment of the mounting end 8 moving radially within the mounting hole 9 being achieved.

Example 6 of a fluid connector assembly in the present invention:

The fluid connector receptacle 1 comprises a receptacle connector 5 and a mounting frame 6. The receptacle connector 5 comprises a body 7 and a mounting end 8 at a mating side facing away from the body 7. The mounting frame 6 is directly provided with a mounting hole 9 for mounting the mounting end 8 and a through hole 19 for fixedly connecting the mounting frame and the equipment body. The mounting end 8 of the receptacle connector 5 is directly inserted into the mounting hole 9 and has an outer diameter smaller than the aperture of the mounting hole 9 such that a radial floating gap 10 exists between the mounting hole 9 and the outer surface of the mounting end 8. A floating retention structure is provided in the floating gap to float and retain the mounting end 8 of the receptacle connector 5 within the mounting hole 9. The floating maintaining structure comprises a first elastic piece and an anti-falling structure. The anti-disengaging structure is arranged on the mounting end 8 and located on both sides of the first elastic member so as to keep the mounting end 8 of the first elastic member and the socket connector 5 in the mounting hole 9. When the socket connector 5 is subjected to external force to cause the mounting end 8 to radially displace and/or deflect relative to the axial direction in the mounting hole 9, the floating holding structure is forced to elastically deform and provide a restoring reaction force to the mounting end 8, so that the floatable adjustment of the mounting end 8 in the mounting hole 9 is realized. A graphical illustration of the radial displacement of the mounting end 8 within the mounting bore 9 may be seen in fig. 6; an illustration of the relative axial deflection of the mounting end 8 within the mounting bore 9 can be seen in fig. 7. The anti-disengagement structure comprises a stop surface 13 between the main body 7 of the receptacle connector 5 and the mounting end 8 of the receptacle connector 5, and a stop structure provided on an end of the mounting end 8 of the receptacle connector 5 remote from the main body 7. An axial distance 16 is provided between the stop surface 13 and the hole edge of the mounting hole 9 to form a deflection gap for deflecting the socket connector 5 relative to the mounting hole 9.

The key to this embodiment is that a second resilient member is arranged within the axial spacing 16. The second elastic member serves to hold the receptacle connector 5 in an axially concentric position with the mounting hole 9 and to urge the receptacle connector 5 to return after the receptacle connector 5 is biased axially with respect to the mounting hole 9 by a force. The anti-drop structure clamps the second elastic member in the axial space 16, which greatly facilitates the next blind insertion.

On the basis of the foregoing, the second elastic member may be a wave spring 17 or a rubber member. The wave spring 17 and the rubber piece have simple structures and small occupied space. By adopting the scheme, the space occupied by the second elastic piece can be reduced, and the occupied space of the fluid connector socket 1 is further reduced. It is easily conceivable that the wave spring 17 here can also be replaced by a conventional spring.

Example 7 of a fluid connector assembly in the present invention:

On the basis of the above embodiment, the key point of this embodiment is that the mounting bracket 6 is an L-shaped steel plate. The mounting hole 9 is provided on one of the side walls of the L-shaped steel plate. The mounting hole 9 extends with a cylindrical outer edge 18 on the hole edge of the side facing away from the body 7 of the socket connector 5 in order to ensure a sufficient axial mounting position of the floating end of the connector on the mounting frame 6. By adopting the scheme, the side of the mounting hole 9, which is away from the main body 7 of the socket connector 5, has a larger space, and the mounting requirement of the socket connector 5 is met on the basis of not increasing the occupied space of the fluid connector socket 1. The mounting frame 6 is further provided with a plurality of through holes 19 so that the mounting frame 6 is fixedly mounted on the relevant equipment by inserting fasteners into the through holes 19. It is conceivable that the L-shaped steel plate may be provided with triangular or rectangular reinforcing ribs at both ends in the extending direction thereof so that both side walls of the L-shaped steel plate have good rigidity.

Example 8 of a fluid connector assembly in the present invention:

On the basis of the above-described embodiment, the key of this embodiment is that the receptacle connector 5 further includes a floating guide 20 provided between the main body 7 and the mounting bracket 6. The floating guide frame 20 is provided with guide structures for mating with guide structures on the fluid connector plug 2. In the blind plugging process, the guiding structure on the fluid connector plug 2 is matched with the guiding structure on the floating guiding frame 20, and the socket connector 5 is guided to adaptively and floatingly displace relative to the position of the plug connector 3, so that the two connectors are conveniently plugged. In this embodiment, the guiding structure on the fluid connector plug 2 is a guiding post 21, and the end of the guiding post 21 is provided with a guiding inclined plane so as to facilitate blind insertion; the guide structure on the floating guide frame 20 is a guide hole 22. It is easily conceivable that the guiding structures on the fluid connector plug 2 may also be guiding holes 22, and correspondingly the guiding structures on the floating guiding frame 20 are guiding posts 21. In addition, the guiding structure on the fluid connector plug 2 may be a guiding strip with one end overhanging, and the guiding structure on the floating guiding frame 20 may be a guiding groove opened at a corresponding position on the surface. The side ends of the guide strips, which are opposite to the bottom of the guide groove, are provided with guide inclined planes for blind insertion.
