Description

Technical Field

[0001] This utility model relates to the field of clamping structures, specifically to a universal clamping fixture for symmetrical dual-port glass needle devices. Background Technology

[0002] Many miniaturized microwave devices still use glass insulators as RF ports, such as... Figure 1 The product shown. Due to miniaturization requirements, this type of product no longer has any connector mounting holes. However, during debugging, a tight and stable connection between the connector and the glass insulator lead-out pin (hereinafter referred to as the glass pin) is required. In the current microwave testing technology field, a clamping block plus screw and nut structure is often used to achieve a tight connection between the connector and the glass pin. (Refer to...) Figure 2 and Figure 3 As shown.

[0003] In the current configuration of the pressure block, screw, and nut, before starting product testing, the two connectors should be passed through the pressure block and the cable respectively for connection (e.g., Figure 4 (As shown), then place the product in the slot, and simultaneously tighten the two nuts on one side of the clamping block towards the center to clamp the connector onto the product. Tightening the nuts, with the aid of a cylindrical sleeve, will take 20-30 seconds. After adjustment, the two nuts need to be tightened outwards again until the desired position is reached, then the product can be removed from the connector. Loosening the nuts, with the aid of a sleeve, will take 10-15 seconds.

[0004] Using this method can indeed achieve the purpose, but it has many drawbacks: (1) Each product needs to be tightened and loosened by two nuts, which is very time-consuming. When the number of products is huge, it is also a test for the debugging personnel; (2) When tightening and loosening the nuts, it is not guaranteed that the two nuts will be tightened and loosened at the same time, which can easily lead to uneven force on the left and right sides of the connector, causing damage such as indentations on the product appearance; (3) No part of the entire structure is fixed. When clamping the product, the pressure block will shake up and down, and the screw will move left and right. Either of these will affect the clamping speed of the product. Moreover, the pressure block will cause the connector to shake together. When the glass pin is not fully inserted into the connector, there may be a risk that the glass pin will be bent.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0017] Compared with the prior art, the embodiments of this utility model have the following advantages and beneficial effects: 1. The universal clamp for symmetrical dual-port glass needle devices provided in this embodiment of the invention initially has the movable limiting member in the starting position and the elastic member unloaded. During clamping, the operator pulls the movable limiting member towards the left vertical plate, at which point the elastic member is compressed and generates elastic force. This elastic force pushes the connector limiting block towards the left vertical plate until it reaches the appropriate position. During this process, the first limiting member on the movable limiting member slides along the second limiting member on the support horizontal plate. When the elastic force of the elastic member reaches a certain resistance, the first limiting member and the second limiting member engage with each other, locking the position of the movable limiting member. At this time, the elastic force of the elastic member firmly clamps the product between the left vertical plate and the connector limiting block, completing the clamping action. When releasing the product, the operator presses the first limiting member to disengage it from the second limiting member, and the elastic member immediately returns to its original state, pushing the movable limiting member back to the starting position. The connector limiting block moves accordingly, releasing the product. The entire clamping and releasing process takes only 1 second, making the operation simple and quick. The uniform thrust provided by the elastic element ensures that the product is subjected to balanced forces on both sides, effectively avoiding product damage that may be caused by uneven forces. This structure not only reduces the workload of debugging personnel, but also improves production efficiency.

[0018] 2. In this embodiment of the utility model, the first and second locking teeth are respectively engaged with the first and second inclined teeth, which ensures the precise locking of the moving limiting component during the clamping process, improves the stability and reliability of the clamping, and the entire clamping and releasing process only takes 1 second. The operation is simple and quick. Pressing the first and second moving blocks can achieve quick unlocking, which improves the debugging efficiency.

[0019] In general, the embodiments of this utility model provide a universal fixture for symmetrical dual-port glass needle devices. By setting a sliding rod, the moving limiting member and the connector limiting block are elastically linked. The first limiting member and the second limiting member cooperate to limit the movement, so as to improve the convenience of debugging and the stability of clamping. Attached Figure Description

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] In the description of this utility model, it should be noted that the terms "first", "second", "third", etc. are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. Example

[0027] Please refer to the reference. Figures 5-8 As shown, this utility model embodiment provides a universal fixture for symmetrical dual-port glass needle devices, including a supporting horizontal plate 1, a left vertical plate 2, and a right vertical plate 3. The left vertical plate 2 and the right vertical plate 3 are respectively vertically arranged on both sides of the supporting horizontal plate 1. A sliding rod 4 is connected between the left vertical plate 2 and the right vertical plate 3. A connector limiting block 5 and a movable limiting member 6 are sleeved on the outside of the sliding rod 4. An elastic member 7 is sleeved on the sliding rod 4. The elastic member 7 is located between the connector limiting block 5 and the movable limiting member 6. Both the connector limiting block 5 and the movable limiting member 6 can slide along the axial direction of the sliding rod 4. A first limiting member 8 is provided on the movable limiting member 6, and a second limiting member 9 is provided on the supporting horizontal plate 1. The first limiting member 8 and the second limiting member 9 are configured to cooperate to limit the movable limiting member 6 to a fixed position on the sliding rod 4. At this time, the elastic member 7 clamps the product between the left vertical plate 2 and the connector limiting block 5.

[0028] Specifically, the support plate 1 is used to fix other components and provide a stable platform. The left vertical plate 2 and the right vertical plate 3 together form the two side supports of the clamp, used to fix the sliding rod 4 and provide a reference surface for product clamping. The right vertical plate 3 is opposite to the left vertical plate 2 and is used to fix the sliding rod 4, together with the left vertical plate 2 forming the two side supports of the clamp. The sliding rod 4 is used to guide the sliding of the movable limiting member 6 and the connector limiting block 5, ensuring their smooth axial movement. The connector limiting block 5 is used to fix the connector, ensuring that the connector remains stable during clamping and preventing it from shaking. The movable limiting member 6 is used to realize the quick clamping and releasing of the product, and realizes the limiting function through cooperation with the first limiting member 8 and the second limiting member 9. The elastic member 7 is located between the connector limiting block 5 and the movable limiting member 6, providing elastic force to push the connector limiting block 5 and the movable limiting member 6 to realize the clamping and releasing of the product. The first limiting member 8 cooperates with the second limiting member 9 to limit the movable limiting member 6 to the fixed position of the sliding rod 4, ensuring the stability of the clamping.

[0029] Before debugging, connect the connector to the testing equipment via cables through the left upright plate and connector limiting block. Insert the product glass needle into the connector. During the clamping process, the moving limiting member 6 is in the initial position, the elastic member 7 is in its natural state, the connector limiting block 5 is located at one end of the sliding rod 4, and the first limiting member 8 and the second limiting member 9 are in an unlocked state. Pull the moving limiting member 6 towards the left upright plate 2 to compress the elastic member 7. The connector limiting block 5 moves towards the left upright plate 2 under the push of the elastic member 7. During the movement, the first limiting member 8 and the second limiting member 9 move relative to each other. When the elastic force of the elastic member 7 prevents the limiting block from moving further, the first limiting member 8 and the second limiting member 9 lock, fixing the moving limiting member 6 in the fixed position of the sliding rod 4. Insert the product glass needle into the connector. The elastic force of the elastic member 7 clamps the product between the left upright plate 2 and the connector limiting block 5, completing the clamping. When it is necessary to remove the product, press the first limit member 8 to release it from the restriction of the second limit member 9 and unlock it. Under the action of elastic force, the elastic member 7 pushes the moving limit member 6 to automatically reset to the starting position. The connector limit block 5 moves accordingly, releasing the product. Then, remove the product that has been debugged and replace it with the next product to be debugged.

[0030] In this embodiment of the invention, by pulling and pressing the movable limiting member 6, and utilizing the elastic force of the elastic member 7, the product can be quickly clamped and released. The operation is simple and quick, with both clamping and releasing operations taking only 1 second. The elastic member 7 provides uniform thrust, ensuring even force distribution on both sides of the product and preventing product damage caused by uneven force, thus protecting the product's appearance. The overall structural design ensures that the clamp will not shake during clamping, further guaranteeing the stability and reliability of the clamping. By reasonably setting the cooperation relationship between the movable limiting member 6 and the limiting member, the clamp can be compatible with miniaturized symmetrical dual-port glass needle devices within a 35mm range, making it widely applicable. The entire clamp can be made of stainless steel, providing a certain weight to ensure that the clamp will not shake during use. At the same time, stainless steel also has good corrosion resistance and durability. The modular design allows for easy disassembly and replacement of various components of the clamp, reducing maintenance costs and time.

[0031] For example, the sliding member 4 includes a first sliding rod 10 and a second sliding rod 11, the elastic member 7 includes a first spring 12 and a second spring 13, the connector limiting block 5 is provided with a first through hole 14 and a second through hole 15, and the moving limiting member 6 is provided with a third through hole 16 and a fourth through hole 17; the first sliding rod 10 passes through the first through hole 14 and the third through hole 16, and the second sliding rod 11 passes through the second through hole 15 and the fourth through hole 17; the first spring 12 is sleeved outside the first sliding rod 10 and is located between the first through hole 14 and the third through hole 16; the second spring 13 is sleeved outside the second sliding rod 11 and is located between the second through hole 15 and the fourth through hole 17; the first sliding rod 10 and the second sliding rod 11 are arranged parallel to each other.

[0032] In this structure, the use of double slide rods and double springs enables efficient and stable product clamping and unclamping. The double slide rods provide a more stable sliding path, reducing potential wobbling during clamping and unclamping. The double springs provide uniform elastic force, ensuring balanced force on both sides of the product and preventing damage caused by uneven force. Of course, in other embodiments, only one slide rod and one spring can be used, or even three or four slide rods and three or four springs, etc., depending on actual needs; no restrictions are imposed here.

[0033] In a preferred embodiment of this utility model, a hollow cavity 18 is provided on the supporting horizontal plate 1, a second limiting member 9 is provided on the inner side wall of the hollow cavity 18, and a first limiting member 8 is provided at the bottom of the movable limiting member 6. When the movable limiting member 6 moves axially relative to the sliding rod member 4, the first limiting member 8 and the second limiting member 9 can generate a meshing motion. This embodiment of the utility model achieves efficient and stable product clamping and unclamping through the meshing motion of the second limiting member 9 in the hollow cavity 18 and the first limiting member 8 at the bottom of the movable limiting member 6.

[0034] It should be noted that the second limiting member 9 can be integrally formed with the inner wall of the hollow cavity 18, or it can be detachably formed by splicing, and there is no limitation here. Exemplarily, in this embodiment of the utility model, it also includes a toothed plate 19, and the second limiting member 9 includes a first oblique tooth 20 and a second oblique tooth 21 disposed on both sides of the toothed plate 19. The toothed plate 19 is installed at the bottom of the supporting horizontal plate 1, and the first oblique tooth 20 and the second oblique tooth 21 are respectively located on opposite sides of the hollow cavity 18; the first limiting member 8 includes a first locking tooth 22 and a second locking tooth 23 disposed on both sides of the movable limiting member 6, the first locking tooth 22 meshes with the first oblique tooth 20, and the second locking tooth 23 meshes with the second oblique tooth 21.

[0035] Specifically, in conjunction with reference Figure 11 and Figure 13 As shown, the first helical tooth 20 and the second helical tooth 21 are respectively disposed on both sides of the toothed plate 19, located on the opposite inner walls of the hollow cavity 18, and engage with the locking teeth on the movable limiting member 6 to achieve locking and releasing functions. Through the meshing of the first helical tooth 20 and the second helical tooth 21 with the first locking tooth 22 and the second locking tooth 23, precise locking of the movable limiting member 6 is achieved, ensuring that the movable limiting member 6 will not spring back due to external force during clamping, thus improving the stability and reliability of clamping. The arrangement of double helical teeth and double locking teeth ensures balanced force on both sides, avoiding product damage caused by uneven force on one side, and further protecting the product's appearance.

[0036] Furthermore, in conjunction with reference Figure 9 , Figure 10 and Figure 12As shown, the movable limiting member 6 includes a first latch 24, a second latch 25, a first movable block 26, and a second movable block 27. The third through hole 16 includes a first locking hole 28 on the first latch 24 through which a first sliding rod 10 passes, a second locking hole 29 on the second latch 25 through which the first sliding rod 10 passes, and a first slot 30 on the first movable block 26. The fourth through hole 17 includes a third locking hole 31 on the first latch 24 through which a second sliding rod 11 passes, a fourth locking hole 32 on the second latch 25 through which the second sliding rod 11 passes, and a second slot 33 on the second movable block 27. Both the first movable block 26 and the second movable block 27 are limited between the first latch 24 and the second latch 25. A third spring 34 is provided on the inner side of the first movable block 26, and a third spring 34 is provided on the inner side of the second movable block 27. A fourth spring 35 is provided on the inner side; a first baffle 36 and a second baffle 37 are provided on the second buckle 25, and there is a gap between the first baffle 36 and the second baffle 37. When the third spring 34 and the fourth spring 35 are in a free state, the free end of the third spring 34 abuts against the first baffle 36, and the fourth spring 35 abuts against the second baffle 37; a first locking tooth 22 is provided at the bottom of the first moving block 26, and a second locking tooth 23 is provided at the bottom of the second moving block 27; when a force is applied inward to the first moving block 26, the third spring 34 is compressed, the first moving block 26 moves closer to the first baffle 36, and the first locking tooth 22 separates from the first helical tooth 20; when a force is applied inward to the second moving block 27, the fourth spring 35 is compressed, the second moving block 27 moves closer to the second baffle 37, and the second locking tooth 23 separates from the second helical tooth 21.

[0037] Specifically, in the initial state, the movable limiting member 6 is in the starting position, and the first spring 12 and the second spring 13 are in a naturally extended state. The third spring 34 and the fourth spring 35 are in a free state, the first locking tooth 22 engages with the first helical tooth 20, and the second locking tooth 23 engages with the second helical tooth 21.

[0038] During the clamping process, the movable limiting member 6 is pulled towards the left upright plate 2, and the first spring 12 and the second spring 13 are compressed, generating elastic force. The elastic force pushes the connector limiting block 5 to move towards the left upright plate 2 along the first slide bar 10 and the second slide bar 11. When the movable limiting member 6 moves to the appropriate position, the first locking tooth 22 engages with the first helical tooth 20, and the second locking tooth 23 engages with the second helical tooth 21, locking the position of the movable limiting member 6. The elastic force firmly clamps the product between the left upright plate 2 and the connector limiting block 5, completing the clamping.

[0039] During the release process, applying inward force to press the first moving block 26 compresses the third spring 34, causing the first moving block 26 to move closer to the first baffle 36. The first locking tooth 22 separates from the first helical tooth 20. Applying inward force to press the second moving block 27 compresses the fourth spring 35, causing the second moving block 27 to move closer to the second baffle 37. The second locking tooth 23 separates from the second helical tooth 21. Under the elastic force, the first spring 12 and the second spring 13 push the moving limit member 6 back to its starting position, and the connector limit block 5 moves accordingly. The product is then released, the debugged product is removed, and the next product to be debugged is replaced. It should be noted that during operation, the first moving block 26 and the second moving block 27 can be pressed simultaneously, causing the first locking tooth 22 to separate from the first helical tooth 20, and the second locking tooth 23 to separate from the second helical tooth 21 synchronously.

[0040] This utility model embodiment ensures the precise locking of the movable limiting member 6 during the clamping process by having the first locking tooth 22 and the second locking tooth 23 engage with the first helical tooth 20 and the second helical tooth 21 respectively, thereby improving the stability and reliability of the clamping. The entire clamping and releasing process takes only 1 second, making the operation simple and quick. Pressing the first moving block 26 and the second moving block 27 can quickly unlock the device, improving debugging efficiency.

[0041] Preferably, the inner diameters of the first locking hole 28 and the second locking hole 29 are adapted to the outer diameter of the first sliding rod 10, and the inner diameters of the third locking hole 31 and the fourth locking hole 32 are adapted to the outer diameter of the second sliding rod 11. The first slot 30 and the second slot 33 are both elongated, with the shorter side of the first slot 30 larger than the diameters of the first locking hole 28 and the second locking hole 29, and the shorter side of the second slot 33 larger than the diameters of the third locking hole 31 and the fourth locking hole 32. The inner ends of the first latch 24 are respectively provided with a first boss 38 and a second boss 39. The first boss 38 is movably installed in the first slot 30, and the second boss 39 is movably installed in the second slot 33. The first latch 24 is provided with a first U-shaped groove 40. A second U-shaped groove 41 is formed between the first baffle 36, the second baffle 37, and the second latch 25. The first U-shaped groove 40 and the second U-shaped groove 41 form a U-shaped opening 42, which isolates the first moving block 26 from the first moving block 26. The second latch 25 is connected to the first boss 38 by bolts, and the second latch 25 is connected to the second boss 39 by bolts.

[0042] Specifically, the first locking hole 28 and the second locking hole 29 are respectively provided on the first latch 24 and the second latch 25, for the first slide rod 10 to pass through. The inner diameter of the first latch 24 is adapted to the outer diameter of the first slide rod 10, ensuring that the first latch 24 and the second latch 25 can slide smoothly along the first slide rod 10. The third locking hole 31 and the fourth locking hole 32 are respectively provided on the first latch 24 and the second latch 25, for the second slide rod 11 to pass through. The inner diameter of the second slide rod 11 is adapted to the outer diameter of the second slide rod 11, ensuring that the first latch 24 and the second latch 25 can slide smoothly along the second slide rod 11. The first slot 30 and the second slot 33 are both elongated and are respectively set on the first moving block 26 and the second moving block 27. The short side of the first slot 30 is larger than the diameter of the first locking hole 28 and the second locking hole 29, and the short side of the second slot 33 is larger than the diameter of the third locking hole 31 and the fourth locking hole 32. This ensures that the first moving block 26 and the second moving block 27 can slide along the axis of the slide rod while ensuring that the first moving block 26 and the second moving block 27 can be pressed and separated from the first helical tooth 20 and the second helical tooth 21.

[0043] The first boss 38 is movably mounted in the first slot 30, and the second boss 39 is movably mounted in the second slot 33, ensuring the relative position of the first latch 24 with the first moving block 26 and the second moving block 27 is stable.
