Description

Technical Field

[0001] This invention relates to the field of liquid cooling connector technology, and in particular to a floating male liquid cooling connector and connector assembly. Background Technology

[0002] Liquid cooling radiators are widely used in industrial cabinets, computer servers, and other applications due to their excellent heat dissipation performance. However, they are bulky and require frequent assembly with circuit boards within the cabinet. To improve the maintenance efficiency of cabinets or servers, quick-connect couplings are typically used. Quick-connect couplings are connection devices that quickly connect or disconnect flow paths (such as gas or liquid flow paths), enabling rapid assembly and disassembly. They are widely used in the liquid cooling industry, such as for the rapid connection of liquid cooling system components in supercomputing and radar. Their key feature is that even when there are assembly errors between the female liquid cooling connector on the blade module and the male liquid cooling connector on the main liquid circuit, the fluid circuit can still be reliably connected.

[0003] A current Chinese utility model patent (CN205896502U) discloses a blind-mating fluid connection element, whose male terminal connector is as follows: Figure 1 On the left side, the waterproofing between the male end body 101 and the equipment is achieved by pressing the sealing ring; while the male end body 101 is in rigid contact with the fixing ring 104. When the male end body 101 moves, one side is pressed against the rubber sealing ring, and the other side rubs against the fixing ring 104, which will generate a large frictional force. Therefore, the lateral force required when it floats is large, which affects the centering adjustment capability. Summary of the Invention

[0004] To address the problems of existing technologies, embodiments of the present invention provide a floating male liquid-cooled connector, which effectively reduces the resistance when the male connector floats.

[0005] The technical solution is as follows:

A support ring is provided at the end of the male valve body.

[0015] The valve body support ring is provided with multiple through holes.

[0016] The valve body and the male end body are provided with a valve body sealing ring.

[0017] The upper and lower rotating parts are thrust bearings.

[0038] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0039] Example 1: A floating male liquid-cooled connector

[0040] In this embodiment, as Figure 1-9As shown, a floating male liquid cooling connector is disclosed, including: a male end housing 11, which is cylindrical, and a cavity 2 is provided inside the male end housing 11. The cavity 2 is connected to the main liquid passage for liquid flow.

[0041] Specifically, such as Figure 2 As shown, a male end body 3 is provided in the cavity 2, and one end of the male end body 3 is located outside the male end housing 11, that is, one end of the male end body 3 extends outside the male end housing 11 for connection with the female end connector.

[0042] The male end body 3 is provided with a male end valve body 4. In its natural state, the male end valve body 4 is tightly fitted with the male end body 3. Only when it is connected to the female end connector, the male end valve body is pushed to move along the axial direction and toward the retaining ring. At this time, the male end valve body is separated from the male end body, so that the liquid can flow.

[0043] Specifically, such as Figure 4 As shown, a retaining ring 5 with a through hole in the middle is provided in the cavity 2, through which the male end body 3 can pass. An upper rotating part 6 and a lower rotating part 7 are respectively provided on the upper and lower sides of the retaining ring 5. A retaining ring 8 is provided at the end of the male end body 3. A main body spring 9 is sleeved between the retaining ring 8 and the lower rotating part 7. That is, the main body spring 9 is sleeved on the outside of the male end body and located between the retaining ring 8 and the lower rotating part 7. The main body spring 9 is in a compressed state. The main body spring 9 squeezes the lower rotating part 7, so that the lower rotating part 7 is in close contact with the retaining ring 5.

[0044] When the male end body 3 is compressed and floats, the upper rotating part 6 bears the pressure. Since the upper rotating part is located on a plane, the male end body 3 can float arbitrarily within the through hole.

[0045] The main spring 9 is supported between the lower rotating part 7 and the retaining ring 8, so that the male end main body 1 always presses against the upper rotating part 6 above, ensuring that the entire structure will not shake.

[0046] Preferably, both the upper rotating component 6 and the lower rotating component 7 are thrust bearings. Thrust bearings are existing standard parts that can be purchased and are flexible and convenient.

[0047] The male end body 3 extends downward and is connected to an elastic tube 10. Since the bottom end of the male end body 3 is connected to the flexible elastic tube 10, the male end body 3 will not be subjected to a large drag force when it floats, and can move freely.

[0048] The male end housing 1 is provided with a male end connector 11 at its end, and the male end connector 11 is connected to the elastic tube 10 to form a liquid flow cavity that is sealed and connected from the male end body, the elastic tube, and the male end connector.

[0049] As an optimization, in this embodiment, for ease of connection, the male connector 11 is threadedly connected to the male housing 1.

[0050] Preferably, the elastic tube 10 is a corrugated elastic tube with one end smaller than the other. The smaller diameter end of the corrugated elastic tube is connected to the male end body 3 by means of flanged riveting to form a whole. The larger diameter end of the corrugated elastic tube is pressed and sealed to the male end housing 1 by means of male end connector 11. That is, a threaded hole is provided on the inner wall of the male end housing. The diameter of the threaded hole is larger than the diameter of the cavity, thus forming a step. The end of the corrugated elastic tube is located at the position of the threaded hole, and then it is pressed by the male end connector to achieve a seal.

[0051] As an optimization, a male end sealing ring 16 is provided on the male end connector 11 to facilitate a sealed connection with the main fluid line pipe.

[0052] like Figure 6 As shown, the male end body 3 is provided with a flange, and the upper rotating member 6 is located between the retaining ring 5 and the flange. The three are closely fitted together to prevent the male end body 3 from shaking.

[0053] like Figure 9 As shown, the male valve body 4 includes a valve head 41 and a valve stem 42. The valve head 41 is frustum-shaped. The inner wall of the male body 3 is provided with an inclined surface adapted to the valve head 41. That is, through the inclined surface and frustum, the male valve body and the male body can be tightly fitted together, while preventing the male valve body from coming out of the male body. A valve body spring 43 is sleeved on the valve stem 42. A support ring 12 is provided at the end of the male body 3. Through the valve body spring 43, the male valve body 43 is tightly fitted with the male body 3 in its natural state under the action of the valve body spring 43.

[0054] As an optimization, valve body sealing rings 13 are provided between the valve head 41 and the male end body 3 to increase the tightness of their mutual cooperation.

[0055] like Figure 7 As shown, the valve body support ring 12 is provided with multiple through holes 121, one of which is located in the center, allowing the valve stem 42 to pass through it in its natural state and facilitating the movement of the male valve body 41 when connected to the female connector. To accelerate liquid flow, the other through holes 121 are arc-shaped, increasing the area of ​​the liquid passage.

[0056] As an optimization, in this embodiment, the valve body support ring 12 is provided with a protruding platform that is adapted to the inner diameter of the male end body 3, that is, the entire valve body support ring is "convex" shaped. The valve body support ring is connected to the male end body 3 through the protruding platform, and the "convex" shaped structure can prevent the valve body support ring from being completely inserted into the male end body, and at the same time, it can also be easily removed from the valve body support ring.

[0057] like Figure 3As shown, a limiting hole 14 is provided on the side wall of the male end housing 1, and at least two limiting holes 14 are symmetrically arranged. A limiting pin 15 adapted to the limiting hole 14 is provided on the male end housing 1.

[0058] As an optimization, the limiting pin 15 and the limiting hole 14 are interference-fitted, which ensures that the male end body 3 can float but will not rotate after connection.

[0059] To better understand the structure of this device, the following description, along with the specific assembly steps, is provided:

[0060] 1. After the sealing ring 13 is fitted onto the male valve body 4, it is inserted into the male body 3 together with the valve body spring 43;

[0061] 2. Install the valve body support ring 12. The valve body support ring 12 and the male end body 3 are interference fit, which can prevent it from falling out after being tightened.

[0062] 3. Install the upper rotating assembly 6 into the male end housing 1, and then install the male end body 3; then install the lower rotating assembly 7 and the body spring 9, and then snap on the retaining ring 8;

[0063] 4. Connect one end of the elastic tube 10 to the tail of the male body 3, and rivet it together to form a whole; press and seal the other end of the elastic tube 10 to the male outer shell 1 using the male connector 11. This completes the device, forming a structure as shown in the image. Figure 1-2 The finished product shown.

[0064] The working principle of this device is as follows:

[0065] When the male end body is compressed and floats, the upper rotating component bears the pressure. The rotating component is a thrust bearing. Since the bearing is located on a plane, the male end body can float freely within the through hole.

[0066] The main body spring is supported between the thrust bearing located below and the retaining ring, so that the male end body is always pressed against the thrust bearing above, ensuring that the entire structure does not wobble;

[0067] Because the base plate of the male end is connected to the flexible rubber corrugated pipe, the male end will not be subjected to a large drag force when it floats, allowing for free movement.

[0068] Example 2: A floating liquid-cooled joint assembly

[0069] This embodiment discloses a floating liquid-cooled connector assembly, including the aforementioned floating male liquid-cooled connector and a female liquid-cooled connector connected to the floating male liquid-cooled connector. No improvement is made to the female connector in this solution; the female connector can be an existing female connector structure, such as the female connector in the blind-insertable fluid connection element disclosed in the existing Chinese Utility Model Patent (CN205896502U). The key is that when the male connector and female connector are inserted, the male body can be guided by the female body to move relative to the limiting pin, thereby aligning with the female body and entering its interior. This allows the female push rod to contact and abut against the male valve body, and the male body to contact and abut against the female valve body. This causes the male valve body to move axially within the male body and the female valve body to move axially within the female body, thus achieving fluid communication.
