Description

Technical Field

[0001] The utility model relates to a joint structure, in particular to a female joint butt joint structure. Background Art

[0002] Quick connectors are often used in fluid transport. Conventional quick connectors typically consist of a male and female connector that work together to achieve quick connection or disconnection. However, due to the limited space in existing cabinets (e.g., data centers), the space available for the male and female connectors to connect and disconnect is very limited, making traditional connector operation difficult.

[0003] For example, conventional male and female connectors may utilize a steel ball locking method to maintain the axial position between the male and female connectors. Figure 1 As shown, to ensure more stable docking between the male and female connectors, conventional female connector structures typically have at least one row of steel balls 91, or multiple rows of steel balls 91 arranged symmetrically or in a staggered pattern, on the tube 90 facing the front end opening for insertion of a male connector (not shown). However, because both the male and female connectors require axial slots to accommodate the steel balls 91, while this method achieves docking, it suffers from issues such as bulk, a long travel length for docking and unlocking, and unstable docking and locking.

[0004] Therefore, the authors of this project and related industry players are eager to research and improve how to address the aforementioned issues of the inconvenience and difficulty of operating traditional male and female connectors due to their long mating travel in existing confined environments (such as data center cabinets and chassis), as well as the various drawbacks derived from this. Utility Model Content

[0005] Therefore, in order to effectively solve the above-mentioned problems, the purpose of the present invention is to provide a female connector docking structure that can reduce the docking and unlocking strokes of the male and female connectors.

[0012] The female joint docking structure, wherein: each of the two spring push plates has two corresponding transverse tenons; each spring push plate is in an upright C-shape, and the two transverse tenons of each spring push plate are respectively arranged at both ends of the C-shape and correspond to each other up and down; the two transverse tenons of the spring push plate protrude toward the front end of the body, so that the cross-sections of the two corresponding fixing frames up and down are clamped between the vertical spacing of the two transverse tenons, and the two spring push plates respectively limit the two fixing frames to be located between the two transverse tenons up and down, and provide balanced limiting force on both the left and right sides.

[0013] The female connector docking structure is characterized in that: a recessed portion is formed at the outer edge of the cross-section where the two fixing frames are limited by the two spring push plates.

[0014] The female connector docking structure is characterized in that: the two fixing frames are further provided with a socket and a plug post suitable for concave-convex matching at the upper and lower docking positions, so that the two fixing frames with the same configuration are connected to each other in a concave-convex manner through the socket and the plug post.

[0015] The female joint docking structure is characterized in that: two pivot grooves are provided on the front side of each fixing frame, and the two pivot grooves are recessed along the same side of the two ends of the cross-section for the axis of the bolt body to be pivoted; the two fixing frames are respectively recessed with a notch towards the center for accommodating the bolt body.

[0016] In the female connector docking structure, the cross section protrudes toward the through hole to form a stop portion, so that the shaft portion is located in the two pivot grooves and is supported by the stop portion to form a limited position.

This structural design of the present invention allows the female connector to have a shorter operating stroke, facilitating locking and unlocking of the docking connection. Furthermore, the axial position of the docking connection is more stable, and the overall structural dimensions are shortened. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The above-mentioned objectives and structural and functional characteristics of the present invention will be described with reference to the preferred embodiments shown in the accompanying drawings.

[0032] Please refer to the attached diagram of this utility model. Figure 2 It is a partial three-dimensional cross-sectional diagram of the mating structure of the female connector and the male connector of the present invention; Figure 3 This is a three-dimensional exploded schematic diagram of the female connector docking structure of the present invention; Figure 4A It is a partially exploded schematic diagram of the female connector docking structure of the present invention; Figure 4B It is a partial three-dimensional assembly diagram of the female connector docking structure of the present invention; Figure 5 is a cross-sectional diagram of the female connector docking structure and the male connector of the present invention; and Figures 6 to 9 It is a partial cross-sectional schematic diagram of the female connector docking structure and the male connector of the present invention.

[0033] As the utility model Figures 2 to 3 As shown, the present invention provides a female connector docking structure (that is, it can also be used as a female connector) for cooperating with a male connector 1 (the male connector 1 can have an inserting section 11, and a groove 12 is recessed on the outer periphery of the inserting section 11, such as an annular groove), which has at least a main body 2, a sleeve spring 3, a snap module 4 and a pull sleeve 5.

[0034] The main body 2 is provided with a through insertion channel 20, so that the male connector 1 can be inserted into the front end of the female connector docking structure with the corresponding insertion section 11. Figure 3 As shown, the body 2 has a docking section 21 adjacent to the front end. Furthermore, corresponding chordal grooves 210 are provided on at least two opposing sides of the outer periphery of the docking section 21, corresponding to the retaining groove 12 of the male connector 1. The chordal grooves 210 can be formed by cutting, tangentially cutting from an eccentric point of the tubular cross-section of the body 2. Each of the opposing chordal grooves 210 has a through hole 210a in communication with the insertion channel 20.

[0035] At this time, the snap module 4 is disposed around the outer periphery of the docking section 21. For example, the portion of the snap module 4 that is disposed around the docking section 21 may be roughly C-shaped, but the portion corresponding to the opposing chordal groove 210 may be designed to be roughly linear. Consequently, the portion of the snap module 4 will engage the opposing chordal groove 210 and be restrained by the walls of the opposing chordal groove 210. In this way, the snap module 4 is interfered with by the opposing chordal groove 210 and axially restrained by the body 2.

[0036] Furthermore, the snap module 4 is pivotally mounted with at least one bolt 41 near the location where it engages the opposing string groove 210. The bolt 41 has an actuating portion 412 and an axis 411. The actuating portion 412 can pass through the through hole 210a and enter the insertion channel 20. The axis 411 is pivotally mounted on the snap module 4, allowing the bolt 41 to rotate relative to the snap module 4. In the present invention, when the actuating portion 412 enters the insertion channel 20 and is subjected to an external force, it can drive the bolt 41 to rotate relative to the snap module 4.

[0037] like Figure 3 and Figure 4A 、 Figure 4B As shown, the snap module 4 is composed of two fixing frames 42 and two spring push plates 43. The fixing frame 42 is C-shaped and elastic. The overall structure is provided in the middle section of the C-shaped arc in the form of a straight strip to form a cross-section 421. The two fixing frames 42 are clipped together at the top and bottom to form an annular body and are provided on the docking section 21, so that the cross-section 421 can be clipped into the relative chord groove 210, so that the snap module 4 is axially limited by the body 2. The two spring push plates 43 are clipped together on the docking section 21 with left and right cooperation. The two spring push plates 43 are provided on the back side of the two fixing frames 42.

[0038] Furthermore, each of the two spring push plates 43 has two corresponding transverse tenons 43a at the top and bottom. Specifically, each spring push plate 43 can be in an upright C-shape, with the two transverse tenons 43a disposed at the top and bottom ends of the C-shape. Because the spring push plates 43 are assembled with the two fixing frames 42 to form the snap-on module 4 mounted on the body 2, the two transverse tenons 43a of the spring push plates 43 can protrude toward the front end of the body 2, so that the cross-sections 421 of the two corresponding fixing frames 42 are clamped between the vertical spacing of the two transverse tenons 43a. Thus, the two spring push plates 43 respectively constrain the two fixing frames 42 to be located between the transverse tenons 43a, providing a balanced limiting force on both the left and right sides.

[0039] In some embodiments, the distance between the two transverse tenons 43a of each spring push plate 43 can also be slightly smaller than the vertical height of the two fixing frames 42 after being matched up and down, and a recessed portion 421a is respectively formed at the outer edge of the cross-sections 421 of the two fixing frames 42 limited by the two spring push plates 43, so that the two elastic fixing frames 42 can deform to allow the transverse tenons 43a to enter between the upper and lower recessed portions 421a. In addition to allowing the transverse tenons 43a of the two spring push plates 43 that are matched on the left and right to contact each other and then resist each other, the transverse tenons 43a are also clamped on the left and right sides by the inner edges of the recessed portions 421a, so as to provide upper and lower limits while preventing left and right separation.

[0040] In addition, in order to make the two fixing frames 42 fit tightly together, a socket 422 and a pin 423 suitable for concave-convex fitting can be provided at both ends of each C-shaped ring extension, that is, the joint where each fixing frame 42 fits with the other up and down, so that when the two fixing frames 42 with the same configuration fit with each other in a point-symmetrical and inverted manner, the sockets 422 and the pins 423 between the two can be plugged into each other in a concave-convex manner.

[0041] In one embodiment, two pivot slots 42a are provided on the front side of each fixing bracket 42. These pivot slots 42a are recessed along the same side of the cross-section 421 at both ends, for pivoting the shaft portion 411 of the bolt body 41. More specifically, each fixing bracket 42 has a recessed notch 42c toward the center for accommodating the bolt body 41. Furthermore, the actuating portion 412 of the bolt body 41 enters the insertion channel 20 through the through-holes 210a, thereby allowing the actuating portion 412 to rotate within the insertion channel 20 about the shaft portion 411.

[0042] Furthermore, the cross-section 421 may protrude toward the through hole 210a to form a stopper 42b, allowing the shaft 411 to be positioned within the pivot slot 42a and supported by the stopper 42b, thereby forming a restrained position. For example, because the shaft 411 is in the shape of a long straight column, the pivot slot 42a must provide a complete opening corresponding to the projected area during assembly; however, the stopper 42b would at least partially obstruct the opening, preventing the projected surface of the shaft 411 facing the opening from fully passing through. However, because the snap modules 4 may be elastic, the stopper 42b can be deformed to allow the shaft 411 to enter the opening, and thereafter, within a certain range of external force, the shaft 411 can be restrained within the pivot slot 42a.

[0043] Furthermore, because the shaft portion 411 rotates with the actuating portion 412, the blocking portion 42b can be the edge of the actuating portion 412 formed at the opening of the pivot groove 42a away from the insertion channel 20, thereby not only preventing it from disengaging, but also when the shaft portion 411 rotates toward the opening side, the rotation of the remaining parts of the bolt body 41 can press the blocking portion 42b, so that the blocking portion 42b can not only block the shaft portion 411 from disengaging from the pivot groove 42a, but also generate a force in the opposite direction of the rotation of the actuating portion 412 due to the elasticity of the material, forcing the bolt body 41 to reverse and return after the external force disappears.

[0044] In addition, an annular positioning groove 210b is formed circumferentially at the rear end of the docking section 21. The sleeve spring 3 is sleeved on the outer periphery of the docking section 21, with its two ends respectively supporting the snap module 4 and the annular positioning groove 210b. In this way, the sleeve spring 3 can provide thrust or elastic force to both ends. During assembly, the sleeve spring 3 can be sleeved first, and then the snap module 4 can be assembled. The annular positioning groove 210b can stably limit the arrangement of the sleeve spring 3 relative to the body 2 of the female connector docking structure, preventing it from disengaging from the annular positioning groove 210b due to external forces. The present invention is not limited to this.

[0045] Finally, after the above assembly is completed, the pull sleeve 5 is arranged on the outer periphery of the sleeve spring 3 and the buckle module 4. In addition, the front end of the buckle module 4 is supported against the pull sleeve 5.

[0046] Specifically, please refer to Figures 3 to 5 As shown, the sleeve spring 3 can be supported on one side of the annular positioning groove 210b and the spring push plate 43 of the buckle module 4, and the front ends of the two fixing frames 42 can be supported on a linkage portion 51 formed by the circumferential inward contraction of the front end of the pull sleeve 5. In this way, the user can apply force to the pull sleeve 5 to drive the buckle module 4 and the sleeve spring 3 to be compressed by the linkage portion 51 and move axially toward the rear end of the female connector docking structure. In addition, in order to prevent the pull sleeve 5 from detaching from the body 2, a limiting ring 52 can be provided on the outer peripheral edge of the docking section 21 corresponding to the front end of the linkage portion 51, which is relatively closer to the front end of the body 2, to limit the linkage portion 51 in the axial direction, so that the pull sleeve 5 cannot detach from the front end of the female connector docking structure in the axial direction.

[0047] In the present invention, the actuating portion 412 passes through the through holes 210a and can rotate within the insertion channel 20. Figure 5 As shown, when the male connector 1 and the female connector docking structure have not yet docked and are not subjected to external force, the sleeve spring 3 will support the rear end of the snap module 4, causing the snap module 4 to be pushed toward the front end of the female connector docking structure by the sleeve spring 3.

[0048] In detail, Figure 4A 、 Figure 4B and Figure 5 As shown, in some embodiments, the front end of the actuating portion 412 of the bolt body 41 is formed into an arc-shaped top surface 412a, and the top surface 412a extends to both sides to form a planar front top abutment surface 413b and a rear top abutment surface 414b, and a front side wall 413a is formed between the front top abutment surface 413b and the shaft portion 411, and a rear side wall 414a is formed between the rear top abutment surface 414b and the shaft portion 411.

[0049] Specifically, the top surface 412a from the shaft portion 411 to the outer end of the actuating portion 412 is the longest rotation radius of the bolt body 41. Therefore, in order to allow the bolt body 41 to rotate, the axial width of the through holes 210a should in principle be larger than the longest rotation radius.

[0050] More specifically, when one of the front sidewall 413a and the rear sidewall 414a is supported, it can lie flat against the corresponding supporting surface. Therefore, when no external force is applied, the support provided by the two ends of the sleeve spring 3 causes the bolt body 41 to rotate forward, causing the front sidewall 413a to rotate and cling to an inner wall of the through-hole 210a. The corresponding rear abutting surface 414b is then pushed against by the spring push plate 43, and the bolt body 41 is restrained in the forward direction by the sleeve spring 3 and an inner wall of the through-hole 210a.

[0051] At this time, please refer to Figure 2 、 Figure 6 As shown, if the plug-in section 11 of the male connector 1 is inserted into the plug-in channel 20 of the body 2 from the front end of the female connector docking structure body 2, the top surface 412a and the front top abutment surface 413b of the actuating portion 412 will be pushed by the inserted plug-in section 11, and the actuating portion 412 will be rotated toward the plug-in channel 20 by the male connector 1.

[0052] Next, see Figure 2 、 Figure 7As shown, as the male connector 1 passes through, the actuating portion 412 will correspond to and fall into the interior of the retaining groove 12 of the male connector 1, thereby axially limiting the male connector 1. Specifically, after the actuating portion 412 falls into the retaining groove 12 of the male connector 1, the top surface 412a and the front abutting surface 413b of the actuating portion 412 abut against the inner wall of the retaining groove 12 of the male connector 1. The front end of the actuating portion 412 abuts against the inner wall of the through hole 210a, and the rear abutting surface 414b is pushed by the spring push plate 43, thereby achieving the axial limiting effect of the retaining groove 12 of the male connector 1. Furthermore, since the actuating portion 412 is limited to this position, the actuating portion 412 falls into the slot 12 of the male connector 1, so that the slot 12 of the male connector 1 is clamped, and the male connector 1 cannot be axially displaced outside the insertion channel 20, thereby achieving the effect of axially limiting the male connector 1.

[0053] In other words, at this time, the bolt body 41 is blocked and cannot rotate outward from the insertion channel 20 at the front end of the female connector docking structure. Therefore, if any external force pulls the male connector 1 in this state, the external force on the male connector 1 will be transmitted to the top surface 412a and the front abutting surface 413b of the bolt body 41 through the inner wall of the slot 12. The external force will then act on the bolt body 41, but will then be resisted by the front side wall 413a of the bolt body 41 against the inner wall of the through hole 210a. As a result, the male connector 1 is axially restricted and cannot axially disengage from the female connector docking structure, thereby stabilizing the docking.

[0054] Come again and see Figure 2 、 Figure 8 As shown, if the user applies external force to move the pull sleeve 5 back toward the rear end of the female connector docking structure (pulling, pushing, pulling, etc.), the snap module 4 will be actively driven back and the sleeve spring 3 will be compressed. The snap module 4 will then drive the bolt body 41 back together. At the same time, the front side wall 413a of the actuating portion 412 is no longer restricted by the inner wall of the through hole 210a, thereby creating the required space for the bolt body 41 to rotate with the inner wall of the through hole 210a.

[0055] Then, see Figure 2 、 Figure 9 As shown, the bolt body 41, which is pushed by the inner side of the slot 12 of the male connector 1, will rotate toward the outside of the plug channel 20 at the front end of the female connector docking structure. At this time, the bolt body 41 rotates outward from the plug channel 20 to disengage from the slot 12 of the male connector 1, that is, the slot 12 of the male connector 1 is no longer axially limited by the bolt body 41, and the male connector 1 can move outward from the plug channel 20. Afterwards, applying external force to move the male connector 1 toward the outside of the plug channel 20 can smoothly disengage the male connector 1 from the plug channel 20. Finally, please refer to Figure 5As shown, after the male connector 1 is completely disengaged from the insertion channel 20 , the bolt body 41 returns to its original position.

[0056] In summary, the present invention utilizes the relative rotation of the bolt body 41 within the opposing chord grooves 210 and through-holes 210a to achieve quick connection and disconnection functions between the male connector 1 and the female connector. The docking stroke is completed after the bolt body 41 rotates through the entire length of the chord grooves 210 or through-holes 210a. The bolt body 41's rotation radius is smaller than the axial width of the opposing chord grooves 210 or through-holes 210a. Therefore, the present invention utilizes the bolt body 41 of the snap module 4 and the pull sleeve 5 to achieve docking and unlocking in a shorter or even very shorter stroke.

[0057] Furthermore, in conjunction with the pull sleeve 5, the present invention utilizes the snap module 4 to be axially displaceable within the opposing chord grooves 210 and through-holes 210a, allowing the bolt body 41 to effectively rotate inwardly and outwardly toward the insertion channel 20 within its axial width, thereby completing docking and unlocking. In summary, the present invention utilizes the bolt body 41 to engage with a male connector 1 inserted into the insertion channel 20 to dock and lock the female connector docking structure. After locking, the pull sleeve 5 is retracted to unlock the bolt body 41, allowing the male connector 1 to disengage from the female connector docking structure.

[0058] In short, when the male connector 1 is inserted into the female connector docking structure, docking is completed, and pulling the pull sleeve 5 backward completes the unlocking of the female connector docking structure, thereby significantly shortening the docking stroke. Therefore, even in a small space such as a cabinet (for example, a data center), the male and female connectors can be quickly and smoothly docked and unlocked.

[0059] Furthermore, the present invention utilizes the bolt body 41 to position the snap module 4 against the inner wall of the through hole 210a, aligned with a plane perpendicular to the axial direction. This allows the snap module 4 to abut against the inner wall of the opposing chord groove 210, thereby preventing tolerance-sensitive issues such as loosening and instability caused by tolerances or unexpected external forces. Consequently, the present invention's joint docking structure has a shorter operating stroke, facilitating locking and unlocking of the joint. Furthermore, it offers greater stability and a smaller footprint.

[0060] The above description has provided a detailed description of the present invention. However, the above description is merely a preferred embodiment of the present invention and should not limit the scope of the present invention. In other words, all equivalent variations and modifications based on the present invention should still fall within the scope of the patent of the present invention.
