Description

Technical Field

[0001] This utility model relates to a female connector structure, and more particularly to a quick-connect female connector structure for water cooling. Background Technology

[0002] The increased computing power of current servers has led to a corresponding increase in the heat generated by their internal computing units. Furthermore, multiple servers are housed in a single server rack with very limited space between them, making it impossible to install additional cooling modules for each server individually. Therefore, manufacturers have adopted water cooling to dissipate heat from the servers within the rack. Because servers contain delicate electronic components, the configuration of the various water cooling pipes must be designed to prevent leaks at any connection point, thereby preventing damage to electronic components caused by water leakage. To prevent leaks, server piping mostly uses rigid or metal pipes for the cooling water system, with male and female connectors on both the server (movable side) and the server rack (fixed side) for quick connection and disconnection of the water lines on both sides. Due to slight radial tolerances during the assembly of the male and female connectors...

[0003] Furthermore, since the male and female connectors may have the same or different specifications, their mating lengths may not be the same. Therefore, after mating, it is impossible to control the depth of the male connector's insertion into the female connector. When the male and female connectors are inserted too deeply, the internal components of the female connector, which serve as the valve body's fixing parts for switching the water circuit, are easily overcompressed, exceeding the stress limit and causing displacement or retraction. This prevents the valve body from returning to its original position to close the water circuit, resulting in leakage. More specifically, as... Figure 1 As shown, the conventional female connector 7 has a single sleeve with a channel inside to accommodate a fixing member. The bottom end of the sleeve has a C-clip 72 for fixing, and the fixing member 73 abuts against the C-clip 72 to prevent it from detaching from the single sleeve. When the male connector (not shown) and female connector 7 are engaged, excessive stress due to length mismatch or excessive insertion depth can easily damage or dislodge the C-clip 72, causing the fixing member 73 on the C-clip 72 to shift or detach from the axis of the single sleeve. Ultimately, this results in the valve body failing to return to its original position to close the water circuit, leading to leakage. Therefore, these shortcomings are the areas that the designer of this project and related industry professionals urgently need to research and improve. Utility Model Content

[0004] Therefore, in order to effectively solve the above problems, the purpose of this utility model is to provide a quick-connect female connector structure that can make the fixed valve structure stable and facilitate assembly.

[0005] To achieve the above objectives, this utility model provides a quick-connect female connector structure, comprising: an outer sleeve, a connecting sleeve, a fixing member, a spring, and a movable member.

[0006] The outer sleeve has an internal accommodating space, and a top stop is provided at the bottom of the outer sleeve inward.

[0007] The fastener is fitted with a spring, and a movable part is movably sleeved at its top end, while a limiting part at its bottom end abuts against the top stop of the outer sleeve.

[0008] The connecting sleeve houses the fixing member, and its bottom end abuts against the limiting portion and is assembled with the outer sleeve.

[0009] The quick-connect female connector structure includes: a threaded groove on the inner surface of the accommodating space inside the outer sleeve; and a connecting part provided in the lower section of the outer sleeve, which can be connected to other devices.

[0010] The quick-connect female connector structure includes: a protruding part at the top of the fixing part, and a first annular sealing element sleeved on the outer ring of the protruding part. The first annular sealing element contacts the inner surface of the moving part, thereby achieving a sealing and waterproof effect.

[0011] The quick-connect female connector structure, wherein: the movable part is hollow and can be movably fitted onto the protrusion at the top of the fixed part; the bottom of the movable part is provided with an annular body that abuts against the spring; and the top of the movable part is provided with a connecting surface.

[0012] The quick-connect female connector structure wherein: the outer ring of the movable part is fitted with a second annular sealing element, the second annular sealing element being able to contact an inner wall surface of the connecting cylinder, thereby achieving a sealing and waterproofing effect.

[0013] The quick-connect female connector structure includes: an insertion channel inside the connecting cylinder, allowing a male connector's insertion section to enter the insertion channel; an inner wall surface is formed inside the connecting cylinder, with a step and a guide slope at the upper end of the inner wall surface.

[0014] The quick-connect female connector structure includes: a third annular seal is provided on the inner wall of the connecting cylinder, which can contact the outer surface of the moving part to achieve a sealing and waterproof effect; a thread is provided on the outer periphery of the connecting cylinder, which can cooperate with the thread groove opened on the inner surface of the outer sleeve; and a connecting part is provided at the lower section of the connecting cylinder, which can enter the receiving space of the outer sleeve.

[0015] In the aforementioned quick-connect female connector structure, after the connecting cylinder is fully locked into the outer sleeve, the end face of the connecting cylinder is flush with the end face of the outer sleeve.

[0016] In the aforementioned quick-connect female connector structure, the bottom of the spring abuts against the limiting part.

[0017] Therefore, this utility model's quick-connect female connector structure uses the outer sleeve and connecting sleeve to connect the fixing member internally and externally, ensuring that the fixing member is securely connected and fixed in the center position of the shaft. When the male connector is engaged with this quick-connect female connector structure, even if an external force is applied to the male connector, even if the external force is too large or does not match the specification length of the male connector, it will not cause the fixing member to shift, thereby achieving the effect of securing the fixing member. This quick-connect female connector structure has the characteristics of simple structure, low failure rate, reliable connection, and good airtightness. Attached Figure Description

[0024] The above-mentioned objectives of this utility model and its structural and functional characteristics will be described with reference to the preferred embodiments shown in the accompanying drawings.

[0025] Figure 2 This is a three-dimensional assembly diagram of the quick-connect female connector structure of this utility model; Figure 3 This is a three-dimensional exploded view of the quick-connect female connector structure of this utility model; Figure 4This is a schematic cross-sectional view of the quick-connect female connector structure of this utility model; and, Figure 5 This is a schematic cross-sectional view of the quick-connect female connector structure and the male connector of this utility model.

[0026] Please refer to this utility model. Figure 2 and Figure 3 As shown, this utility model provides a quick-connect female connector structure, comprising an outer sleeve 1, a fixing member 2, a connecting sleeve 5, a spring 3, and a movable member 4. This quick-connect female connector structure is designed to mate with a male connector 6, which can be inserted into the quick-connect female connector structure to achieve mutual connection between the male connector 6 and the quick-connect female connector structure.

[0027] Please refer to this utility model. Figure 3 and Figure 4 As shown, the outer sleeve 1 has an internal accommodating space 12, and a threaded groove 14 is formed on the inner surface of the accommodating space 12 inside the outer sleeve 1. A connecting part 11 is provided at the lower section of the outer sleeve 1, and the connecting part 11 can be connected to other devices. A top stop part 13 is provided inward from the bottom end of the outer sleeve 1. The top stop part 13 is an annular platform extending inward from the bottom end of the outer sleeve 1. The annular platform has a stable supporting effect and can provide support for objects pressing on the top stop part 13, so as to provide a stable structure so that the objects on the top stop part 13 will not shift or fall off the outer sleeve 1, thereby limiting the objects on the top stop part 13 to a vertical axial position. The outer sleeve 1 is a one-piece molded structure.

[0028] The fastener 2 is located inside the outer sleeve 1. A limiting portion 21 protrudes from the bottom of the fastener 2, which abuts against the bottom of the connecting sleeve 5. In other words, the fastener 2 abuts against the top stop portion 13 of the outer sleeve 1 via the limiting portion 21. In other words, because the top stop portion 13 of the outer sleeve 1 restricts the axial displacement of the fastener 2, the fastener 2 is confined within the outer sleeve 1, preventing it from detaching from the bottom of the outer sleeve 1 and ensuring it is stably positioned on the top stop portion 13. The fastener 2 is fitted with the spring 3, the bottom of which abuts against the limiting portion 21 of the fastener 2. The top of the fastener 2 has a protrusion 22, the outer ring of which is fitted with a first annular seal 221. The first annular seal 221 contacts the inner surface of the movable part 4, thereby achieving a sealing and waterproofing effect.

[0029] The movable component 4 is located at the top of the fixed component 2. More specifically, the movable component 4 is hollow and can be movably fitted onto the protrusion 22 at the top of the fixed component 2. However, since the inner diameter of the movable component 4 is larger than the outer diameter of the protrusion 22, the movable component 4 can be displaced axially relative to the protrusion 22 of the fixed component 2. The bottom of the movable component 4 has an annular body 41, and the top of the movable component 4 has a connecting surface 42. The movable component 4 abuts against one end of the spring 3 via the annular body 41. After the connecting cylinder 5 is locked inside the outer sleeve 1, the upper end of the annular body 41 is supported by the stepped portion 541 of the connecting cylinder 5, and the lower end of the annular body 41 is supported by the spring 3, thereby placing the annular body 41 in the first position, and thus limiting the movable component 4 to that position. The outer ring of the movable part 4 is fitted with a second annular seal 43, which can contact the inner wall surface 54 of the connecting cylinder 5, thereby achieving a sealing and waterproofing effect.

[0030] The connecting cylinder 5 houses the fixing member 2, with its bottom end abutting against the limiting portion 21 and connected to the outer sleeve 1. An insertion channel 53 is provided inside the connecting cylinder 5, allowing the insertion section 61 of the male connector 6 to enter the insertion channel 53. An inner wall surface 54 is formed inside the connecting cylinder 5, with a step 541 and a guide slope 542 at its upper end. The step 541 is a structure formed by the upper end of the inner wall surface 54 of the connecting cylinder 5 protruding inward. Furthermore, because the upper end of the inner wall surface 54 of the connecting cylinder 5 protrudes inward, it presents a trapezoidal shape relative to the lower surface, thus the step 541 has the effect of axially limiting the corresponding object. The guide slope 542 is located at the uppermost edge of the inner wall surface 54 of the connecting cylinder 5, forming an annular slope along the inner wall surface 54. The inner wall surface 54 of the connecting cylinder 5 is provided with a third annular seal 543, which can contact the outer surface of the movable part 4 to achieve a sealing and waterproofing effect. A thread 52 is provided on the periphery of the connecting cylinder 5, which can be engaged with the threaded groove 14 formed on the inner surface of the outer sleeve 1. A connecting portion 51 is provided at the lower section of the connecting cylinder 5, which can enter the receiving space 12 of the outer sleeve 1. The connecting cylinder 5 is a one-piece molded structure.

[0031] Because the diameter of the outer sleeve 1 is larger than the outer diameter of the connecting sleeve 5, the connecting sleeve 5 can be locked into the outer sleeve 1. When the connecting sleeve 5 enters the receiving space 12 of the outer sleeve 1, the connecting portion 51 of the connecting sleeve 5 first enters the receiving space 12 of the outer sleeve 1, and then the connecting sleeve 5 is rotated so that the thread 52 of the connecting sleeve 5 and the thread groove 14 of the outer sleeve 1 engage with each other, so that the connecting sleeve 5 can be locked into the outer sleeve 1. After the connecting sleeve 5 is fully locked into the outer sleeve 1, the end face of the connecting sleeve 5 is flush with the end face of the outer sleeve 1.

[0032] The quick-connect female connector structure of this utility model can be assembled in the following manner; however, other methods can be used, and it is not limited to this operation method. For example... Figures 2 to 4 As shown, during the assembly process, the fixing member 2 can be placed inside the outer sleeve 1 first. Since the bottom end of the outer sleeve 1 is provided with the top stop 13, the fixing member 2 will be located on the top stop 13. Then, the spring 3 is sleeved around the fixing member 2, and then the movable member 4 is pressed down against the spring 3. Finally, the connecting sleeve 5 is locked inside the outer sleeve 1. During the locking process, the fixing member is clamped between the top stop of the outer sleeve and the bottom end (joint edge) of the connecting sleeve, which can securely bind the fixing member between the two. This ensures that the fixing member is located in the center position of the shaft within the female connector, and prevents the fixing member from shifting or detaching from the outer sleeve 1 due to excessive external force or mismatch with the specification length of the male connector when the male and female connectors are connected.

[0033] Please refer to this utility model. Figure 3 and Figure 5 As shown, the male connector 6 has a plug section 61 and a neck 62. The bottom end of the plug section 61 has a plug surface 611, and the lower edges of both ends of the neck 62 form a mating plane 621. When the male connector 6 is engaged with the quick-connect female connector structure of this utility model, the male connector 6 enters the plugging channel 53 of the connecting cylinder 5, and the plug section 61 of the male connector 6 abuts against the movable member 4. More specifically, the plug surface 611 at the bottom end of the plug section 61 contacts the connecting surface 42 of the movable member 4, and the mating plane 621 contacts the guide slope 542 of the connecting cylinder 5.

[0034] When a user applies an external force to the male connector 6, the force pushes the male connector 6 downward, thereby transmitting the force to the movable part 4. Since the lower end of the movable part 4 abuts against the spring 3 through the annular body 41, the spring 3 is compressed, causing it to deform. Because the spring 3 is sleeved around the fixing part 2, and its bottom abuts against the limiting part 21, the external force is transmitted to the limiting part 21 of the fixing part 2. Since the limiting part 21 of the fixing part 2 is abutted by the stop part 13 of the outer sleeve 1, the axial displacement of the fixing part 2 is restricted, ensuring the fixing part 2 is securely contained within the outer sleeve 1, and the stop part 13 of the outer sleeve 1 counteracts the external force.

[0035] In summary, the quick-connect female connector structure of this utility model, through the structural design of the outer sleeve 1, the fixing member 2, and the connecting sleeve 5, ensures that the fixing member 2 is securely confined within the female connector. This prevents the fixing member 2 from shifting or detaching from the outer sleeve 1 due to excessive external force or mismatch in length with the male connector. This improves upon the conventional method where the female connector 7 is fixed by a C-clip 72 to support the fixing member 73. In this method, the C-clip 72 is easily damaged or detached from the fastening point due to excessive external force or mismatch in specifications. This causes the fixing member 73 on the C-clip 72 to shift or detach from the axis of the female connector 7, resulting in the valve body failing to return to its original position to close the water circuit and causing leakage.

[0036] The present invention has been described in detail above. However, the above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made based on the present invention should still fall within the patent coverage of the present invention.
