Description

Technical Field

[0001] This invention relates to a fluid connector, specifically to a side-out fluid connector socket and fluid connector and device. Background Technology

[0002] As electronic systems become increasingly integrated, the heat density of these systems continues to rise, leading to a greater preference for liquid cooling technology. Liquid cooling offers advantages such as low noise, small size, and high heat dissipation efficiency. With technological advancements, electronic devices are trending towards miniaturization, creating an urgent need for micro-miniature fluid connectors to facilitate fluid transfer between modules and chassis.

[0003] To reduce the size of fluid connectors, existing fluid connectors, such as... Figure 1 As shown, the flow channel of a plug is typically a side-out type, while the flow channel of a socket is typically a tail-out type. For example, in the patent with publication number "CN113819326B" and invention title "A Miniature Fluid Connector and its Assembly," the side wall of the plug housing has a flow channel hole, forming a side-out type flow channel. The tail of the socket has a stop block with a flow channel on it. The device on which the socket is installed needs to have a cavity located axially in front of the fluid connector. When drilling holes in the product (i.e., the device on which the socket is installed, requiring holes to be drilled in the device to install the socket), a flow channel needs to be reserved at the tail of the socket. The space dimensions cannot meet the needs of some user scenarios, such as scenarios where axial space requirements are relatively strict. Therefore, a side-out type socket is needed.

DETAILED DESCRIPTION

[0022] 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 of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0023] An embodiment of the side-out type fluid connector socket of the present application is shown in FIG. 1, hereinafter referred to as side-out type socket 15, which comprises a socket housing 1, a sealing ring 2, a sealing rod 3, a spring 7, a circlip 8, and a pressing block 9. The opposite end of the side-out type socket 15 is referred to as the front end. Figure 3 The socket housing 1 is used to support the entire side-out type socket 15. The socket housing 1 is fixed on the housing of the device II 13, and the outer wall of the socket housing 1 is nested with an O-ring I 4. After the socket housing 1 is installed in the mounting hole on the device II 13, the sealing between the socket housing 1 and the device II 13 is achieved through the O-ring I 4. The socket housing 1 is provided with a cavity extending axially therethrough, and a plurality of side-out holes I 101 are distributed circumferentially on the wall of the socket housing 1. The side-out holes I 101 communicate the cavity in the socket housing 1 with the space outside, and after the side-out type socket 15 is installed on the device II 13, the side-out holes I 101 are located in the device flow passage II 14 inside the housing of the device II 13, thereby being able to communicate the device flow passage II 14 with the cavity of the socket housing 1.

[0024] The cavity of the front end of the socket housing 1 is slidably provided with the sealing ring 2, which is used to cooperate with the plug and to realize the opening and closing of the internal passage of the fluid connector through the sliding of the sealing ring 2. The outer wall of the sealing ring 2 is nested with an O-ring II 5, which is arranged between the sealing ring 2 and the socket housing 1. During the sliding of the sealing ring 2, the sliding sealing between the sealing ring 2 and the socket housing 1 is achieved. A plurality of side-out holes II 201 are distributed circumferentially on the wall of the sealing ring 2, and the side-out holes II 201 communicate the cavity in the sealing ring 2 with the cavity in the socket housing 1. The side-out holes II 201 are located at the rear side of the O-ring II 5. The rear end of the sealing ring 2 is provided with a spring limiting column 202 extending rearward, and the front end of the spring 7 is sleeved on the spring limiting column 202. The spring limiting column 202 is located at the rear side of the side-out holes II 201. Through the limiting cooperation of the spring limiting column 202 and the spring 7, the failure caused by the deflection of the spring 7 during the extension and contraction of the spring 7 can be avoided.

[0025]

[0026] ​A pressure block 9 is nested inside the cavity at the rear end of the socket housing 1. The front end face of the pressure block 9 abuts against the step on the inner wall of the rear end of the socket housing 1. A retaining spring 8 is nested inside the inner wall of the rear end of the socket housing 1. The retaining spring 8 stops the step on the outer wall of the pressure block 9. The retaining spring 8 cooperates with the step on the inner wall of the socket housing 1, so that the pressure block 9 is limited to the rear end of the socket housing 1. A spring limiting groove 901 for limiting the spring 7 is opened at the front end of the pressure block 9. The rear end of the spring 7 is nested in the spring limiting groove 901. A sealing rod fixing post 902 protrudes forward in the spring limiting groove 901.

[0027] The sealing rod fixing post 902 has a threaded hole, and the rear end of the sealing rod 3 has a stud that is threadedly connected to the threaded hole. The sealing rod 3 extends forward out of the socket housing 1, and the front end of the sealing rod 3 forms a sealing protrusion 301 with a larger outer diameter. An O-ring Ⅲ6 is nested in the outer wall of the sealing protrusion 301. The sealing ring 2 is fitted on the sealing rod 3. When the sealing ring 2 slides to the front end, the inner wall of the front end of the sealing ring 2 and the sealing protrusion 301 are sealed by the O-ring Ⅲ6, thus closing the flow channel inside the socket. When the sealing ring 2 moves backward, it disengages from the sealing protrusion 301, allowing the flow channel inside the socket to open. There is a gap between the sealing ring 2 and the sealing rod 3, allowing a flow channel to be formed between them. The spring 7 is fitted on the sealing rod fixing post 902, the sealing rod 3, and the spring limiting post 202. The rear end of the spring 7 abuts against the bottom surface of the spring limiting groove 901, and the front end abuts against the step on the outer wall of the rear end of the sealing ring 2.

[0028] When the sealing ring 2 is not subjected to backward pressure, the spring force of the spring 7 causes the front end of the sealing ring 2 to engage with the sealing protrusion 301, thus sealing the flow channel within the socket and closing it. The front end of the sealing ring 2 rests against the step at the front end of the sealing rod 3, preventing the sealing ring 2 from dislodging from the sealing rod 3. Pushing the sealing ring 2 backward overcomes the spring force of the spring 7, causing the sealing ring 2 to disengage from the sealing protrusion 301 and opening the flow channel within the socket. After the plug is disconnected from the socket, the spring 7 provides a restoring force to the sealing ring 3, causing the sealing ring 2 to re-engage with the sealing protrusion 301, achieving self-sealing. The sealing rod 3, in the disconnected state, engages with the sealing ring 2 to achieve self-sealing; when the plug is inserted, it pushes the sealing valve core 17 on the plug, opening the fluid channel.

[0029] Side outlet holes (side outlet hole I 101 and side outlet hole II 201, respectively) are added to the side walls of the socket housing 1 and the sealing ring 2. A portion of the equipment flow channel II 14 inside the equipment II 13 overlaps with a portion of the side outlet type socket 15, such as Figure 2 As shown, compared to existing technologies, such as Figure 1As shown, after the direct-output socket 10 is installed on device I 11, device flow channel I 12 needs to be set on its rear side, occupying space in the axial direction of the device. The present invention can reduce the size occupied in the axial direction of device II 13, reduce the axial space occupied, and facilitate the miniaturization of the device.

[0030] In existing technologies, such as Figure 1 As shown, the spring is limited by the inner wall of the socket housing to ensure that the spring does not deviate in the direction of extension and contraction, and the spring size is relatively large. After the socket and plug are inserted, the spring is compressed. After the fluid passes through the gap between the sealing ring and the sealing rod, it can only flow out of the socket housing along the space inside the compressed spring and enter the flow channel I12 of the device. The compressed spring occupies a large flow channel space, and the fluid flows along the flow channel space where the spring is located, which increases the flow resistance. In this invention, the size of the spring 7 is reduced compared to the spring in the prior art. It is sleeved on the rear end of the sealing ring 2. The sealing ring 2 is provided with a side outlet hole I201 at the front side of the spring 7. The spring 7 is sleeved on the rear end of the sealing ring 2. Compared with the limitation by the socket housing, the compressed spring 7 will not block the flow of fluid. After the fluid enters the sealing ring 2, it flows into the socket housing 1 through the side outlet hole II201, and then flows out through the side outlet hole I101 on the socket housing 1. It does not need to pass through the spring 7, which reduces the resistance of the spring 7 to the fluid flow, shortens the flow distance of the fluid in the fluid connector, increases the flow channel space size, and further reduces the flow resistance.

[0031] The plug that matches the side-out socket in this invention is as follows: Figures 4 to 6 As shown, the device includes a plug housing 16, which also has a side outlet hole. When the plug is not subjected to an insertion force, the sealing valve core 17 inside the plug housing 16 is located in the opening at the front end of the plug housing 16, and an O-ring IV 18 is nested in the inner wall of the opening. When the sealing valve core 17 is in the opening, the flow channel inside the plug is disconnected. A spring (not shown in the figure) can be installed inside the plug housing 16 to keep the sealing valve core 17 in the opening. When subjected to an insertion force, the sealing valve core 17 enters the plug housing 16, opening the flow channel inside the plug.

[0032] During the insertion and connection of the socket and plug, firstly, the sealing valve core 17 on the plug and the sealing rod 3 on the socket come into contact, see... Figure 4 Then, as the insertion depth of the plug and socket increases, the sealing rod 3 pushes the sealing valve core 17 into the plug housing 16. The opening of the sealing ring 2 and the plug housing 16 achieves sealing between the plug and socket in the inserted state through the O-ring IV 18. At this time, the flow channel is not open. Figure 5; continue to make the plug and socket plug, with the increase of the depth of plug, plug shell 16 opening edge push seal ring 2 front end of the outer wall of the step, the seal ring 2 and seal block 301 relative movement of the front end of the seal rod 3, seal between the seal ring 2 and seal block 301, seal valve core 17 continue to move into the plug shell 16, plug and socket gradually remove self-sealing, open fluid passage, start transmission fluid, see Figure 6 .

[0033] In other embodiments, on the basis of the above-mentioned embodiments are improved, the socket shell 1 and the pressure block 9 is set up, therefore, no need to set the snap spring 8.

[0034] In other embodiments, on the basis of the above-mentioned embodiments are improved, the seal rod 3 and the pressure block 9 can be connected by buckle structure, instead of threaded connection, improve the assembly efficiency.
