Description

Technical Field

[0001] This invention relates to the field of high-speed backplane connector technology, specifically a high-speed backplane connector with a locking function. Background Technology

[0002] High-speed backplane connectors are a common type of connector used in large communication equipment, ultra-high performance servers and supercomputers, industrial computers, and high-end storage devices. They mainly consist of two connection boards, each with multiple densely packed plugs and sockets. The connection between the two connection boards is achieved by matching the densely packed plugs with the corresponding sockets.

[0003] Existing high-speed backplane connectors, after being plugged in, do not have a device to ensure that the two connecting plates fit tightly without shrinking back. They mainly rely on the insertion and friction between multiple plugs and sockets to maintain this fit. However, after the plugs and sockets are plugged in, there is a slight springback phenomenon under the reaction force, which makes the connecting plates not fit tightly. This can easily affect signal transmission. Furthermore, during the process of installation and use in equipment, when subjected to external forces, the connection between the plugs and sockets can easily loosen, affecting the stability of signal transmission.

[0004] Therefore, we propose a high-speed backplane connector with locking function. Summary of the Invention

[0007] The movable component includes a connecting plate and multiple support plates that are fixedly connected to the second connecting plate. A fixing plate is fixedly connected to the top of the support plate. The fixing plate has a first sliding groove with a T-shaped cross-section. A first sliding plate is slidably fitted in the first sliding groove of one of the fixing plates. Multiple connecting rods that pass through the first sliding groove and are connected to the connecting plate are fixedly connected to the top of the first sliding plate. A plug-in block is fixedly connected to the end of the first sliding plate. A toothed plate that is fixedly connected to the pressure plate is provided through the plug-in block. The toothed plate extends into the connecting plate.

[0008] Preferably, the pressing component includes an incomplete gear that rotates within the connecting plate. The incomplete gear meshes with the toothed plate. A rotating rod extending through the connecting plate is fixedly connected to the central shaft of the incomplete gear. A turntable is fixedly connected to the rotating rod, and a groove is provided at the edge of the turntable. A ratchet tooth that engages with the toothed plate is rotatably connected within the connecting plate. A pressing post that engages with the turntable is fixedly connected to the end of the ratchet tooth. A tension spring connected to the connecting plate is attached to the side of the ratchet tooth. A fixing component is provided at the end of the rotating rod to ensure the position of the toothed plate and to continuously rotate the rotating rod to adjust the angle and complete the insertion and fixing.

[0009] Preferably, the fixing assembly includes a rotating plate fixedly connected to the rotating rod, a connecting rod extending through the rotating plate, and multiple connecting holes arranged in a circular matrix on the connecting plate for insertion and engagement with the connecting rod. A first compression spring connected to the rotating plate is connected to the connecting rod. Preferably, the supporting assembly includes two torsion spring rods rotatably connected to the second connecting plate, a first rotating plate fixedly connected to the torsion spring rod, a sliding groove on the first rotating plate, a sliding column slidably engaged within the sliding groove, a second sliding groove communicating with the first sliding groove on the side of one of the fixing plates, second rotating plates extending through the second sliding grooves fixedly connected to both sides of the first sliding plate, the second rotating plates being fixedly connected to the sliding columns, and the angle between the first rotating plate and the second rotating plate forming an acute angle.

[0010] Preferably, the support assembly further includes a second slide plate that slides within the first sliding groove, the top surface of the second slide plate is rotatably connected to a rotating column, a rotating rod that passes through the rotating column is fixedly connected to the torsion spring rod, the outer surface of the plug block is provided with a plug hole that engages with the second slide plate, the horizontal cross-sectional dimension of the plug hole is larger than the horizontal cross-sectional dimension of the second slide plate, and the plug block is also provided with a plug assembly for fixing the second slide plate.

[0011] Preferably, the plug-in assembly includes a pressing rod located in the plug hole, an embedding groove that mates with the pressing rod is provided at the bottom of the second sliding plate, a movable rod is movably fitted inside the plug-in block, a second compression spring is wound around the outer surface of the movable rod, and the two ends of the second compression spring are respectively connected to the pressing post and the plug-in block.

[0012] Preferably, the sides of the turntable and the pressing post extend through the connecting plate to facilitate observation of the relative positions of the pressing post and the groove.

[0017] Preferably, the arc length of the groove is consistent with the arc length of the end of the tooth on the incomplete gear, ensuring that the distance the incomplete gear drives the tooth plate to move is consistent with the distance the pressing column moves within the groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, the first connecting plate is inserted into the second connecting plate, and then the connecting plate is manually moved so that the pressure plate moves to the middle of the top surface of the first connecting plate. Then, the insertion rod is rotated so that the incomplete gear drives the toothed plate to move downward. When the incomplete gear moves away from the toothed plate, the ratchet locks the toothed plate with the cooperation of the turntable and the pressure column, preventing the toothed plate from resetting upward, ensuring the tight fit between the first connecting plate and the second connecting plate, thereby locking the insertion fit between the first connecting plate and the second connecting plate and ensuring that no springback occurs.

[0020] 2. The two second sliding plates that move simultaneously are inserted into the plug-in block, thereby supporting the entire plug-in block and connecting plate together through one first sliding plate and two second sliding plates, ensuring that the supporting force of the pressure plate pressing down is uniform and stable.

[0021] 3. When fixed, the rotating plate can rotate at a large angle (greater than 90 degrees), which makes it easy for the plug rod to be inserted into one of the plug holes under the action of the first compression spring. This insertion method has strong applicability. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] Please see Figure 1-3 The high-speed backplane connector with locking function shown in the figure includes a first connecting plate 1 and a second connecting plate 2 that are plugged into each other; it also includes a pressure plate 3; a movable component 4, which is used to move the pressure plate 3 to the middle of the first connecting plate 1; a pressure component 13, which is used to move the pressure plate 3 against the first connecting plate 1 and prevent the pressure plate 3 from retracting; and a support component 26, which enables the pressure component 13 to move smoothly.

[0038] Please see Figures 4-8 The movable component 4 in the figure includes a connecting plate 5 and multiple support plates 6 that are fixedly connected to the second connecting plate 2. A fixed plate 7 is fixedly connected to the top of the support plate 6. A first sliding groove 8 with a T-shaped cross-section is opened on the fixed plate 7. A first sliding plate 9 is slidably fitted in the first sliding groove 8 of one of the fixed plates 7. Multiple connecting rods 10 that pass through the first sliding groove 8 and are connected to the connecting plate 5 are fixedly connected to the top of the first sliding plate 9. A plug-in block 11 is fixedly connected to the end of the first sliding plate 9. A toothed plate 12 that is fixedly connected to the pressure plate 3 is provided through the plug-in block 11. The toothed plate 12 extends into the connecting plate 5.

[0039] Please see Figures 11-12 The pressing component 13 shown in the figure includes an incomplete gear 14 that rotates within the connecting plate 5. The incomplete gear 14 meshes with the toothed plate 12. A rotating rod 15 that passes through the connecting plate 5 is fixedly connected to the central shaft of the incomplete gear 14. A turntable 16 is fixedly connected to the rotating rod 15. A groove 17 is provided at the edge of the turntable 16. A ratchet 18 that engages with the toothed plate 12 is rotatably connected within the connecting plate 5. A pressing post 19 that engages with the turntable 16 is fixedly connected to the end of the ratchet 18. A tension spring 20 connected to the connecting plate 5 is attached to the side of the ratchet 18. A fixing component 21 is provided at the end of the rotating rod 15 to ensure the position of the toothed plate 12 and to continuously rotate the rotating rod 15 to adjust the angle and complete the insertion and fixing.

[0040] Please see Figure 6 and Figures 11-12 The fixed component 21 shown in the figure includes a rotating plate 22 that is fixed to the rotating rod 15. A plug-in rod 23 is provided through the rotating plate 22. A plurality of plug-in holes 24 are arranged in a circular matrix on the connecting plate 5 to engage with the plug-in rod 23. A first compression spring 25 connected to the rotating plate 22 is connected to the plug-in rod 23.

[0041] The connecting plate 5 extends through the sides of the turntable 16 and the pressing column 19 to facilitate observation of the relative position of the pressing column 19 and the groove 17. The angle between the first sliding groove 8 and the two insertion holes 36 is 120°. The bottom surface of the pressing plate 3 is provided with a rubber anti-slip layer. The diameter of the turntable 16 is larger than the diameter of the incomplete gear 14. The arc length of the groove 17 is consistent with the arc length of the end of the tooth on the incomplete gear 14.

[0042] In this embodiment, the first connecting plate 1 is inserted into the second connecting plate 2 (the first connecting plate 1 is not obstructed by the position of other structures). Then, the connecting plate 5 is manually moved, and the first sliding plate 9 and the connecting rod 10 move along the first sliding groove 8, thereby moving the connecting plate 5, the insertion block 11, and the pressure plate 3. When the pressure plate 3 moves to the middle of the top surface of the first connecting plate 1, the insertion block 11 is stopped and fixed by the support assembly 26. When the insertion block 11 and the pressure plate 3 are stably stopped at the middle of the top surface of the first connecting plate 1, the insertion rod 23 is pulled out, causing the insertion rod 23 to disengage from the insertion hole 24. Then, the rotating rod 15 is rotated around the pivot. The rotation of the rotating rod 15 drives the incomplete gear 14 and the turntable 16 to rotate synchronously. When the incomplete gear 14 meshes with the toothed plate 12, the groove 17 on the turntable 16 is in contact with the pressure post 19. The incomplete gear 14 drives the incomplete gear 14 to rotate synchronously. When the toothed plate 12 moves, the pressing post 19 is located in the groove 17, and under the action of the tension spring 20, the ratchet 18 rotates, and the end of the ratchet 18 moves away from the toothed plate 12, thereby releasing the fixation on the toothed plate 12, so that the incomplete gear 14 can drive the toothed plate 12 to move, thereby causing the toothed plate 12 to drive the pressing plate 3 to press down on the first connecting plate 1, making the first connecting plate 1 fit more tightly against the second connecting plate 2. When the incomplete gear 14 disengages from the toothed plate 12, the pressing post 19 just disengages from the groove 17, thereby causing the ratchet 18 to rotate and re-engage the toothed plate 12, ensuring that the toothed plate 12 does not move. Continue to rotate the rotating plate 22 (adjust the position of the toothed plate 12 once for each rotation) until the first connecting plate 1 and the second connecting plate 2 fit tightly and meet the requirements. The first connecting plate 1 and the second connecting plate 2, which are interlocked, are locked together and there will be no springback phenomenon.

[0043] When the first connecting plate 1 and the second connecting plate 2 fit tightly and meet the requirements, the rotating plate 22 is rotated left and right. The direction of rotation depends on the relative position of the groove 17 and the pressing post 19. The pressing post 19 is always ensured to not coincide with the position of the groove 17, so that the ratchet 18 is always locked with the toothed plate 12 and the position of the toothed plate 12 is guaranteed. In this method, the rotating plate 22 can rotate at a large angle (greater than 90 degrees), which makes it easy for the insertion rod 23 to be inserted into one of the insertion holes 24 under the action of the first compression spring 25. This insertion method has strong applicability.

[0044] Example 2

[0045] This second embodiment is a further supplement and explanation of the first embodiment. Please refer to [link / reference]. Figures 4-5as well as Figure 10 The support assembly 26 shown in the figure includes two torsion spring rods 27 rotatably connected to the second connecting plate 2. A first rotating plate 28 is fixedly connected to the torsion spring rods 27. A sliding groove 29 is provided on the first rotating plate 28. A sliding column 30 is slidably fitted in the sliding groove 29. A second sliding groove 31 communicating with the first sliding groove 8 is provided on the side of one of the fixed plates 7. A second rotating plate 32 passing through the second sliding groove 31 is fixedly connected to both sides of the first sliding plate 9. The second rotating plate 32 is connected and fixed to the sliding column 30. The angle between the first rotating plate 28 and the second rotating plate 32 is an acute angle.

[0046] The support assembly 26 also includes a second slide plate 33 that slides within the first sliding groove 8. A rotating post 34 is rotatably connected to the top surface of the second slide plate 33. A rotating rod 35 that passes through the rotating post 34 is also fixedly connected to the torsion spring rod 27. An insertion hole 36 that engages with the second slide plate 33 is provided on the outer surface of the insertion block 11. The horizontal cross-sectional dimension of the insertion hole 36 is larger than the horizontal cross-sectional dimension of the second slide plate 33. An insertion assembly 37 for fixing the second slide plate 33 is also provided in the insertion block 11.

[0047] In this embodiment, as the first sliding plate 9 moves, it drives the second rotating plate 32 to move along the second sliding groove 31. The second sliding groove 31, through the action of the sliding groove 29 and the sliding column 30 (the angle between the first rotating plate 28 and the second rotating plate 32 is acute, and the two are relatively inclined), causes the first rotating plate 28 to rotate around the torsion spring rod 27 as the rotation axis, thereby causing the rotating rod 35 to rotate. The second sliding plate 33 moves along the first sliding groove 8 through the rotating shaft, and the rotating shaft rotates adaptively. The rotating shaft slides on the rotating rod 35. When the plug-in block 11 moves to the middle of the top surface of the first connecting plate 1, the second sliding plate 33 is inserted into the plug hole 36, and the insertion is ensured to be stable by the plug-in assembly 37. Thus, the entire plug-in block 11 and the connecting plate 5 are supported by one first sliding plate 9 and two second sliding plates 33. This avoids the situation where the pressure plate 3 has a single support point (i.e., only receives support from the position of the first sliding plate 9) when the pressure assembly 13 presses down, resulting in uneven pressure effect.

[0048] The horizontal cross-sectional dimension of the insertion hole 36 is much larger than that of the horizontal cross-sectional dimension of the second sliding plate 33, ensuring that the second sliding plate 33 slides into the insertion hole 36 and can move within the insertion hole 36. The vertical height of the insertion hole 36 is slightly greater than that of the second sliding plate 33.

[0049] Example 3

[0050] This third embodiment is a further supplement and explanation of the second embodiment. Please refer to [link / reference]. Figure 9The plug-in assembly 37 shown in the figure includes a pressing rod 38 located in the plug hole 36. The bottom of the second slide plate 33 is provided with an embedding groove 39 that cooperates with the pressing rod 38. A movable rod 40 is movably fitted inside the plug-in block 11. A second compression spring 41 is wound around the outer surface of the movable rod 40. The two ends of the second compression spring 41 are respectively connected to the pressing post 19 and the plug-in block 11.

[0051] In this embodiment, during the process of the second sliding plate 33 sliding into the insertion hole 36, the second sliding plate 33 presses against the pressing rod 38, causing the pressing rod 38 to move downward under the action of the movable rod 40, and the pressing rod 38 passes the end of the bottom surface of the second sliding plate 33. Under the action of the second compression spring 41, the pressing rod engages with the embedding groove 39, thereby connecting and fixing the two second sliding plates 33 to the insertion block 11, ensuring that the insertion block 11 and the pressing plate 3 are positioned at the middle of the top surface of the first connecting plate 1, which facilitates subsequent control of the pressing plate 3 pressing against the first connecting plate 1. Through the pressing of the pressing plate 3, the insertion fit between the first connecting plate 1 and the second connecting plate 2 is locked, avoiding the phenomenon of springback reset, which would cause the insertion to loosen.
