Description

Technical Field

[0001] The invention relates to a female joint structure, in particular to a quick-connect female joint structure for water cooling. Background Art

[0002] As the computing performance of current servers increases, the heat generated by the internal computing units also increases. In addition, multiple servers are installed in a server cabinet at the same time, and the space between each server is very narrow, so it is impossible to set up additional heat dissipation modules to dissipate heat for each server one by one. Therefore, the industry has used water cooling to provide heat dissipation for each server in the server cabinet. Since the server has precise electronic parts, various water cooling pipe configurations must avoid water leakage at each connection point to prevent damage to electronic components caused by water leakage. In order to prevent water leakage, most of the server pipes use hard or metal pipes to configure the cooling water pipes, and a male and a female connector are correspondingly provided on the server (movable side) and the server cabinet (fixed side) for docking, so that the water channels on the movable side and the fixed side can be quickly connected or separated. Because the male and female connectors will have a small radial tolerance when assembled.

[0003] In addition, since the male and female connectors may have the same or different specifications, the lengths of the matching connectors may be different. Therefore, after the connection, it is impossible to control the depth of the male connector inserted into the female connector. When the male and female connectors are inserted too deeply into each other, it is easy for the female connector, which is used as a fixing part of the valve body to switch the water channel, to be over-squeezed and exceed the stress, causing displacement or retreat, making it impossible to return the valve body to its original position to close the water channel, thus causing water leakage. In more detail, if Figure 1 As shown, the female connector 7 of the conventional technology has a single sleeve, and the single sleeve has a channel inside to accommodate a fixing member, and the bottom end of the sleeve is provided with a C buckle 72 for fixing and providing a fixing member 73 to abut against the C buckle 72 to prevent the fixing member from detaching from the single sleeve; when the male connector (not shown) and the female connector 7 are engaged, due to the mismatch of length or too deep insertion depth, excessive stress will be generated, which may easily cause the C buckle 72 to be damaged or detached from the buckle, and then the fixing member 73 set on the C buckle 72 will be offset and detached from the axial centerline position of the single sleeve, and finally cause the valve body to be unable to return to the position to close the waterway and cause water leakage, etc. The various defects derived from this are the direction that the inventor of this case and the relevant industry practitioners engaged in this industry are eager to study and improve.

DETAILED DESCRIPTION

[0024] The above-mentioned objects and the structural and functional characteristics of the present invention will be described based on the preferred embodiments shown in the accompanying drawings.

[0025] Figure 2 It is a three-dimensional assembly schematic diagram of the quick-connect female connector structure of the present invention; Figure 3 It is a three-dimensional exploded schematic diagram of the quick-connect female connector structure of the present invention; Figure 4 is a schematic diagram of a combined cross-section of a quick-connect female connector structure of the present invention; and, Figure 5 It is a schematic cross-sectional view of the combination of the quick-connect female connector structure and the male connector of the present invention.

[0026] Please refer to the present invention Figure 2 and Figure 3 As shown, the present invention provides a quick-connect female joint structure, which has an outer sleeve 1, a fixing member 2, a coupling sleeve 5, a spring 3, and a movable member 4. The quick-connect female joint structure of the present invention cooperates with a male joint 6, and the male joint 6 can be plugged into the quick-connect female joint structure to achieve the effect of connecting the male joint 6 and the quick-connect female joint structure to each other.

[0027] Please refer to the present invention Figure 3 and Figure 4 As shown, the outer sleeve 1 has an accommodating space 12 inside, and a threaded groove 14 is provided on the inner surface of the accommodating space 12 inside the outer sleeve 1. A connecting portion 11 is provided at the lower section of the outer sleeve 1, and the connecting portion 11 can be connected to other devices. A top stop 13 is provided inwardly at the bottom end of the outer sleeve 1. The top stop 13 is an annular platform extending inwardly from the bottom end of the outer sleeve 1. The annular platform has a supporting and stable effect, and can provide support for objects above the top stop 13, so as to provide a stable structure so that the objects above the top stop 13 will not deviate or detach from the outer sleeve 1, and the objects on the upper end of the top stop 13 are limited to a vertical axial position. The outer sleeve 1 is an integrally formed structure.

[0028] The fixing member 2 is located in the outer sleeve 1. A limiting portion 21 is protruded from the bottom end of the fixing member 2 to abut against the top stop portion of the bottom end of the engagement tube 5, that is, the fixing member 2 abuts against the top stop portion 13 of the outer sleeve 1 through the limiting portion 21. In other words, since the top stop portion 13 of the outer sleeve 1 limits the axial displacement of the fixing member 2, the fixing member 2 is limited in the outer sleeve 1, and the fixing member 2 will not be separated from the bottom of the outer sleeve 1, and is stably located on the top stop portion 13 of the outer sleeve 1. The fixing member 2 is penetrated by the spring 3, and the bottom of the spring 3 abuts against the limiting portion 21 of the fixing member 2. A protruding portion 22 is protruded from the top end of the fixing member 2, and the outer ring of the protruding portion 22 is sleeved with a first annular seal 221, and the first annular seal 221 contacts the inner surface of the movable member 4, thereby achieving a sealing and waterproof effect.

[0029] The movable member 4 is disposed at the top of the fixed member 2. Specifically, the movable member 4 is hollow and can be movably mounted on the protrusion 22 at the top of the fixed member 2. However, since the inner diameter of the movable member 4 is larger than the outer diameter of the protrusion 22, the movable member 4 can be displaced in the axial direction relative to the protrusion 22 of the fixed member 2. An annular body 41 is disposed at the bottom of the movable member 4, and a connecting surface 42 is disposed at the top of the movable member 4. The movable member 4 is pressed against one end of the spring 3 through the annular body 41. After the coupling tube 5 is locked in the outer sleeve 1, since the upper end of the annular body 41 is supported by the step 541 of the coupling tube 5, the lower end of the annular body 41 is supported by the spring 3, so that the annular body 41 is located at the first position, and the movable member 4 is also limited to this position. The outer ring of the movable member 4 is sleeved with a second annular seal 43 , and the second annular seal 43 can contact the inner wall surface 54 of the coupling tube 5 , thereby achieving a sealing and waterproof effect.

[0030] The coupling tube 5 accommodates the fixing member 2, and its bottom end abuts against the limiting portion 21 and is assembled with the outer sleeve 1. A plug-in channel 53 is provided inside the coupling tube 5, so that a plug-in section 61 of the male connector 6 can enter the plug-in channel 53. An inner wall surface 54 is formed inside the coupling tube 5, and the upper end of the inner wall surface 54 has a step portion 541 and a guide slope 542. The step portion 541 is a structure formed by the upper end of the inner wall surface 54 of the coupling tube 5 protruding inwardly. Further, since the upper end of the inner wall surface 54 of the coupling tube 5 protrudes inwardly, relative to the surface below, it presents a trapezoidal shape, so the step portion 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 coupling tube 5, and is an inclined surface formed along the inner wall surface 54 in an annular shape. The inner wall surface 54 of the coupling tube 5 is provided with a third annular seal 543, which can contact the outer surface of the movable member 4, thereby achieving a sealing and waterproof effect. The outer periphery of the coupling tube 5 is provided with a thread 52, which can be used to cooperate with the thread groove 14 provided on the inner surface of the outer sleeve 1. The lower section of the coupling tube 5 is provided with a coupling portion 51, which can enter the accommodating space 12 of the outer sleeve 1. The coupling tube 5 is an integrally formed structure.

[0031] Since the aperture of the outer sleeve 1 is larger than the outer diameter of the engagement sleeve 5, the engagement sleeve 5 can be locked into the outer sleeve 1. When the engagement sleeve 5 enters the accommodation space 12 of the outer sleeve 1, the coupling portion 51 of the engagement sleeve 5 first enters the accommodation space 12 of the outer sleeve 1, and then the engagement sleeve 5 is rotated to allow the thread 52 of the engagement sleeve 5 to cooperate with the thread groove 14 of the outer sleeve 1, so that the engagement sleeve 5 can be locked into the outer sleeve 1. After the engagement sleeve 5 is completely locked into the outer sleeve 1, the end surface of the engagement sleeve 5 is flush with the end surface of the outer sleeve 1.

[0032] The assembly method of the quick-connect female connector structure of the present invention can be achieved by the following method, but other methods can be used for assembly and are not limited to this operation method. Figures 2 to 4 As shown, during the assembly process, the fixing member 2 can be placed in the outer sleeve 1 first. Since the top stop 13 is arranged inwardly at the bottom of the outer sleeve 1, the fixing member 2 will be located on the top stop 13. Then, the spring 3 is sleeved on the outer periphery of the fixing member 2, and then the movable member 4 is pressed downward against the spring 3, and then the coupling tube 5 is locked in the outer sleeve 1. During the locking process, the fixing member is clamped by the top stop of the outer sleeve and the bottom end (end edge of the coupling part) of the coupling tube and can be firmly combined between the two, so that the fixing member can be ensured to be limited to the center position of the shaft in the female joint, and the fixing member will not be offset or separated from the outer sleeve 1 due to excessive external force or mismatch with the specification length of the male joint when the male and female joints are combined.

[0033] Please refer to the present invention 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 bonding plane 621. When the male connector 6 is engaged with the quick-connect female connector structure of the present invention, the male connector 6 enters the plug channel 53 of the engagement tube 5, and the plug section 61 of the male connector 6 abuts against the movable part 4. More specifically, the plug surface 611 at the bottom end of the plug section 61 contacts the connecting surface 42 of the movable part 4, and the bonding plane 621 contacts the guiding inclined surface 542 of the engagement tube 5.

[0034] When the user applies an external force to the male connector 6, the external force pushes the male connector 6 downward, and then transmits the external force to the movable member 4. Since the lower end of the movable member 4 presses against the spring 3 through the annular body 41, the spring 3 is compressed, so that the spring 3 is compressed and deformed. Since the spring 3 is sleeved on the periphery of the fixing member 2, the bottom of the spring 3 presses against the limiting portion 21, and then the external force is transmitted to the limiting portion 21 of the fixing member 2. Since the limiting portion 21 of the fixing member 2 is pressed by the top stop portion 13 of the outer sleeve 1, the axial displacement of the fixing member 2 is limited, so that the fixing member 2 is firmly limited in the outer sleeve 1, and the top stop portion 13 of the outer sleeve 1 will offset the external force.

[0035] In summary, the quick-connect female connector structure of the present invention is designed by combining the outer sleeve 1, the fixing member 2 and the coupling sleeve 5, so that the fixing member 2 can be firmly limited in the female connector, and the fixing member 2 will not be offset or separated from the outer sleeve 1 due to excessive external force or mismatch in the specification and length of the male connector, so as to improve the conventional female connector 7 which is fixed by the C buckle 72 to support the fixing member 73. The conventional C buckle 72 is easily damaged or separated from the buckle due to excessive external force or mismatch in specifications, thereby causing the fixing member 73 arranged on the C buckle 72 to be offset and separated from the axial centerline position of the female connector 7, resulting in the valve body being unable to return to its position to close the water path, resulting in water leakage and the like.

[0036] The above is a detailed description of the present invention, and the above is only a preferred embodiment of the present invention, which should not limit the scope of the present invention. That is, all equivalent changes and modifications made according to the present invention should still fall within the scope of the patent of the present invention.
