Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically, to a floating socket module, a floating plug module, and a fluid connector assembly. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] In existing technologies, floating modules of blind-mating fluid connectors are used in liquid-cooled servers with blind-mating architectures in data centers. During use, server nodes are pushed into the liquid-cooled rack, and automatic docking is achieved through the floating module, thus completing the synchronous connection of the liquid cooling circuit, power supply, and signals. However, existing fluid floating connectors have the following shortcomings in practical applications: the floating range is small, only able to compensate for small positional deviations; after docking, the plug and socket exhibit a tilt angle, affecting the connector's sealing performance and leading to leakage in the liquid cooling system; and when the plug and socket are disconnected, the floating end connector cannot return to its initial centered state, affecting subsequent insertion and removal. Therefore, there is a need to invent a fluid connector assembly with a larger floating space and automatic reset capability to overcome the deficiencies of existing floating connector assemblies.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that in the description of this utility model, the terms "first," "second," etc., are used only for descriptive purposes and to distinguish similar objects; there is no order between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0029] like Figure 2 As shown, a floating socket module 200 according to this application includes a floating part, wherein the floating part includes a floating plate 6 and at least one socket 5 mounted on the floating plate 6 (e.g., Figure 3 (As shown); socket mounting plate 4, the socket mounting plate 4 is provided with at least one socket mounting hole 41, the floating part includes a mounting post, the mounting post passes through the socket mounting hole 41, and there is a radially floating gap between the mounting post and the socket mounting hole 41. Figure 4As shown, a return spring 8 is provided inside the socket mounting hole 41. The return spring 8 is sleeved on the outside of the mounting post. The return spring 8 has a large coil portion 82 and a small coil portion 81. The small coil portion 81 fits against the outer wall of the mounting post, and the large coil portion 82 fits against the inside of the socket mounting hole 41. When radial floating occurs between the mounting post and the socket mounting hole 41, the return spring 8 can apply a restoring force to the mounting post to return it to its initial position. In the fluid connector assembly of this utility model, the floating plate 6 is clearance-fitted with the mounting post, and the mounting post is sleeved with a return spring 8, allowing the floating portion to float radially between the floating part and the socket mounting plate 4. This solves the problem of inaccurate positioning caused by positional deviation when the plug 2 and the socket 5 are inserted, allowing the socket 5 to adaptively align with the plug 2, avoiding port damage caused by forced oblique insertion. Furthermore, under the restoring force of the return spring 8, the socket module 200 can return to its initial position without affecting subsequent insertion and removal.

[0030] like Figure 3 and 5 As shown, the floating plate 6 includes a plate portion 62 and a guide seat 61 disposed on one side of the plate portion 62. The guide seat 61 has at least one axially oriented guide hole 611, and the opening portion 612 of the guide hole 611 is a conical opening with a large end diameter and a small internal diameter. Figure 2-4 As shown, one end of the socket 5 is a plug-in end for mating with the plug 2, and the other end of the socket 5 is a socket connection end 51. The plate portion 62 is provided with a through hole for the socket connection end 51 to pass through, and an axial extension along the edge of the through hole towards one side of the socket connection end 51 forms a mounting cylinder wall 63. The socket connection end 51 passes through the mounting cylinder wall 63, and the socket connection end 51 and the mounting cylinder wall 63 form the mounting post. The small coil portion 81 of the return spring 8 fits against the outer wall of the mounting cylinder wall 63. The plug-in end of the socket 5 and the guide seat 61 are located on the same side of the plate portion 62.

[0031] In a preferred embodiment, the diameter of the middle portion of the return spring 8 is smaller than the diameter of both ends, forming a small loop portion 81 in the middle and large loop portions 82 at both ends. The end of the socket mounting hole 41 closest to the socket 5 is the first end, which is machined with an internal thread and connected to a mounting nut 7 through the internal thread. The other end of the socket mounting hole 41 is the second end, which has an annular retaining edge. The return spring 8 is constrained between the mounting nut 7 and the annular retaining edge. A retaining ring 10 is installed on the outer wall of the socket connecting end 51, and a retaining ring 9 is installed between the retaining ring 10 and the second end of the socket mounting hole 41, blocking the retaining ring 10 outside the socket mounting hole 41. The floating part includes two sockets 5, the plate part 62 is provided with two through holes, and the two sockets 5 pass through corresponding through holes. The guide seat 61 is provided with two guide holes 611 along the axial direction.

[0032] like Figure 1 As shown, a floating plug module 100 according to this application includes a plug mounting plate 1, a guide post 3 mounted on the plug mounting plate 1, and a plug 2. The guide post 3 and the plug body are located on the same side of the plug mounting plate 1, and the guide post 3 is threaded into the mounting plate. The guide post 3 is used to insert into the guide hole 611, and the plug 2 is used to insert into the socket 5. The end of the guide post 3 has a tapered structure that matches the opening 612 of the guide hole 611.

[0033] like Figure 6 As shown, the plug mounting plate 1 has two plug mounting holes 11, corresponding to two plugs. The outer wall of the plug connection end 21 has an external thread. After the plug connection end 21 passes through the corresponding plug mounting hole 11, it is inserted into the mounting hole of the server to complete the assembly of the floating plug module 100. Each plug has a retaining ring 22 arranged circumferentially on its side wall. The outer diameter of the retaining ring 22 is larger than the inner diameter of the plug mounting hole 11, so that the plug is axially positioned in the plug mounting hole 11. One of the plug mounting holes 11 has a widening groove 12 (e.g., ...) near the retaining ring 22. Figure 7 As shown, the diameter of the enlarged groove 12 is larger than the outer diameter of the retaining ring 22, so that one of the plugs can float axially. This structure can eliminate the poor flatness of the plug mounting surface and avoid the phenomenon that the plug cannot be installed properly due to poor flatness, so as to ensure the reliability of plug and socket 5 mating.

[0034] like Figure 8The diagram shows a fluid connector assembly formed by connecting the floating plug module 100 and the floating socket module 200 of this application. In use, the floating plug module 100 is threaded onto the distributor. The plug module 100 and the socket module 200 need to be connected to achieve connectivity of the liquid cooling system.

[0035] The assembly process of the floating socket module 200 is as follows: Figure 2 As shown, first, the return spring 8 is installed into the socket mounting hole 41 of the socket mounting plate 4, and then the mounting nut 7 is screwed into the internal thread of the socket mounting hole 41 to fix the spring axially upward. Then, the socket is assembled through the socket floating plate 6, which is equivalent to a floating part (e.g., Figure 3 (As shown). Pass the floating component through the mounting plate and secure it to the socket mounting plate 4 using the retaining ring 9 and the retaining ring 10, thus completing the assembly of the socket floating module. The assembled socket module 200 is shown below. Figure 4 As shown.

[0036] like Figure 9 As shown, in actual use, when the plug module 100 and the socket module 200 are not aligned, the contact point of the guide post 3 of the plug module 100 is located on the tapered opening 612 of the guide hole 611 of the socket module 200. The driving force is decomposed into axial force and radial force, and the radial force can push the return spring 8. The small coil 81 of the return spring 8 moves radially under force, causing the floating part to float, that is, the floating plate 6 and the socket move radially synchronously. When the floating part moves to a certain position, the guide post 3 of the plug module 100 can be inserted into the guide hole 611 of the socket module 200, at which point the plug and the socket are properly aligned. When the socket module 200 and the plug module 100 are disconnected, the return spring 8 of the socket module 200 is no longer subject to additional driving force, the small coil 81 returns to the axial position, and causes the floating part to reset.

[0037] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
