[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 This is a schematic diagram of a preferred embodiment of a PCB board connector provided by the present invention; Figure 2 for Figure 1 The diagram shows the structural top of the base plate. Figure 3 for Figure 1 The diagram shows the structure of the bottom of the PCB board. Figure 4 for Figure 2 The enlarged schematic diagram of part A is shown. A PCB connector includes: a base plate 1;

[0032] Fixing holes 3 are formed around the inside of the base plate 1. Fixing posts 4 are fixedly installed on both sides of the fixing holes 3 and on the top of the base plate 1. A sliding groove 5 is formed on the inner side of the fixing post 4. A sliding rod 6 is fixedly installed inside the sliding groove 5. Hollow sliders 7 are slidably connected on both sides of the surface of the sliding rod 6 and inside the sliding groove 5. A spring 8 is provided on the outer side of the hollow slider 7 and on the surface of the sliding rod 6. A rotating shaft 9 is rotatably connected to the inner side of the hollow slider 7. A connecting rod 10 is rotatably connected to the inner side of the rotating shaft 9. An arc-shaped extrusion plate 11 is rotatably connected to the inner side of the connecting rod 10.

[0033] PCB board 12 is disposed on the top of the base plate 1, and insert posts 14 are fixedly installed on both sides of the bottom of the PCB board 12.

[0034] The elastic deformation of the spring 8 ensures that the arc-shaped pressing plate 11 is always under force and can stably clamp the insert 14. By using the slide rod 6 and the hollow slider 7, the spring 8 will not be squeezed and its position will not shift when the hollow slider 7 presses the spring 8.

[0035] A limiting post 13 is fixedly installed at the bottom of the PCB board 12 and inside the insertion post 14.

[0036] Limiting concave columns 2 are fixedly installed on both sides of the top of the base plate 1 and outside the fixing holes 3.

[0037] The diameter of the fixing hole 3 is the same as the diameter of the insertion post 14.

[0038] The stability of the PCB board 12 mounted on its base plate 1 can be improved by the cooperation between the limiting post 13 and the limiting concave post 2, and the limiting post 13 can be inserted into the limiting concave post 2.

[0039] The working principle of the PCB connector provided by this invention is as follows:

[0040] When it is necessary to connect the PCB board 12 and the base plate 1 together, the positions of the insert pins 14 and the fixing holes 3 can be aligned. Then, the PCB board 12 is pushed downwards, causing the limiting pins 13 and the insert pins 14 to move downwards until the bottom of the insert pins 14 contacts the inner side of the arc-shaped extrusion plate 11. The PCB board 12 can be pushed downwards further, causing the insert pins 14 and the limiting pins 13 to continue moving downwards under force. Subsequently, the insert pins 14 will move downwards and press the arc-shaped extrusion plate 11 to both sides. Then, the arc-shaped extrusion plate 11 will be subjected to force and move towards the fixing pin 4. At the same time, the movement of the arc-shaped extrusion plate 11 can drive the connecting rod 10 to move, and the angle change caused by the movement of the connecting rod 10 can push its hollow slider 7, causing the hollow slider 7 to move from the inside to the outside on the surface of the slide rod 6 and inside the slide groove 5. The movement of the hollow slider 7 can compress the spring 8, causing the spring 8 to undergo elastic deformation until the distance between the two arc-shaped extrusion plates 11 is the same as the diameter of the insert 14. At the same time, the insert 14 will pass through the two arc-shaped extrusion plates 11 and be inserted into the fixing hole 3 from top to bottom.

[0041] At the same time, the limiting post 13 is inserted into the limiting concave post 2 from the top opening of the limiting concave post 2, and the installation operation is completed at the same time.

[0042] The force of the elastic deformation of the spring 8 pushes the hollow slider 7 inward. The movement of the hollow slider 7 causes the connecting rod 10 to be stressed, which in turn causes the arc-shaped extrusion plate 11 to be stressed inward and press the insertion post 14 to clamp and fix it. At the same time, the limiting post 13 is inserted into the limiting concave post 2.

[0043] Compared with related technologies, the PCB connector provided by the present invention has the following advantages:

[0044] The structure, consisting of base plate 1, fixing hole 3, fixing column 4, slide groove 5, slide rod 6, hollow slider 7, spring 8, rotating shaft 9, connecting rod 10, arc-shaped extrusion plate 11, PCB board 12, and insert post 14, allows for convenient and quick installation and disassembly. Its simple structure and easy operation improve installation and disassembly efficiency and reduce maintenance costs.

[0045] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 This is a schematic diagram of a preferred embodiment of a PCB board connector provided by the present invention; Figure 2 for Figure 1 The diagram shows the structural top of the base plate. Figure 3 for Figure 1 The diagram shows the structure of the bottom of the PCB board. Figure 4 for Figure 2 The enlarged schematic diagram of part A is shown. A PCB board connection structure includes: a fixing plate 15, with L-shaped grooves 16 on both sides inside the fixing plate 15, and a mounting plate 17 on the top of the fixing plate 15.

[0046] The mounting plate 17 has fixing grooves 18 on both sides of its bottom.

[0047] An adapter slider 19 is slidably connected inside the fixing groove 18, and an L-shaped rod 20 is fixedly installed at the bottom of the adapter slider 19.

[0048] A pull rod 21 is fixedly installed on the outer side of the L-shaped rod 20.

[0049] The L-shaped rod can be easily pulled outwards by the pull rod 21, thus reducing the difficulty of operation.

[0050] The bottom shape and size of the L-shaped rod 20 are matched with the top opening shape and size of the L-shaped groove 16. After the L-shaped rod 20 is inserted into the L-shaped groove 16, it moves inward, thus causing the L-shaped rod 20 and the L-shaped groove 16 to misalign and interlock.

[0051] The PCB board can be mounted on the top of the mounting plate 17.

[0052] A connecting groove 22 is provided inside the mounting plate 17 and on the inner side of the fixing groove 18.

[0053] A tension spring 23 is provided inside the communicating groove 22, and the outer side of the tension spring 23 is fixedly connected to the inner side of the adapter slider 19.

[0054] The stability of the L-shaped rod 20 can be improved by the cooperation between the fixed groove 18 and the adapter slider 19. The elastic deformation of the tension spring 23 ensures that the L-shaped rod 20 is always subjected to an inward pulling force, so that the L-shaped rod 20 can be stably inserted into the L-shaped groove 16 during operation, thus ensuring a stable connection between the fixed plate 15 and the mounting plate 17.

[0055] The working principle of the PCB board connection structure provided by this invention is as follows:

[0056] When it is necessary to connect the fixing plate 15 and the mounting plate 17, the pull rods 21 on both sides can be pulled outwards simultaneously. The pull rods 21 move outwards under the force, which in turn drives the L-shaped rod 20 to move outwards. The outward movement of the L-shaped rod 20 then drives the adapter slider 19, causing it to move from the inside to the outside inside the fixing groove 18. The simultaneous movement of the two adapter sliders 19 at different positions stretches the tension spring 23, causing it to undergo elastic deformation until the adapter slider 19 moves to the outermost position.

[0057] At the same time, the top openings of the L-shaped rod 20 and the L-shaped groove 16 are aligned. Then, the mounting plate 17 can be pushed down to move the related structure downward until the bottom of the L-shaped rod 20 is inserted into the top opening of the L-shaped groove 16. Once fully inserted, the pull rod 21 can be released to pull it outward, and the elastic deformation of the tension spring 23 will simultaneously pull the adapter slider 19 inward, causing it to move from the outside to the inside in the fixing groove 18. At the same time, the L-shaped rod 20 will move inward in the L-shaped groove 16. Thus, the L-shaped rod 20 and the L-shaped groove 16 are misaligned and interlocked, thereby completing the installation operation.

[0058] Compared with related technologies, the PCB board connection structure provided by the present invention has the following advantages:

[0059] The connection between the fixed plate 15 and the mounting plate 17 can be performed in a simple manner through the cooperation of the structure such as the fixed plate 15, L-shaped groove 16, mounting plate 17, fixed groove 18, adapter slider 19, L-shaped rod 20, pull rod 21, connecting groove 22, and tension spring 23. The structure is simple and the manufacturing cost is low.

[0060] Second Embodiment

[0061] Please refer to the accompanying diagram. Figure 7 Based on the PCB connector provided in the first embodiment of this application, the second embodiment of this application proposes another PCB connector. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0062] Specifically, the second embodiment of this application provides a PCB board connector that differs in that the PCB board connector has a connecting port 24 at the top and bottom of the right side of the fixing post 4, a connecting post 30 is provided inside the connecting port 24, a fixing ring 25 is provided on the outer side of the surface of the slide rod 6, the outer side of the fixing ring 25 is fixedly installed to the inner side of the connecting post 30, and a mounting block 26 is fixedly installed at the top and bottom of the right side of the fixing post 4, and a threaded rod 27 is rotatably connected to the inner side of the mounting block 26.

[0063] Threaded blocks 28 are fitted on both sides of the surface of the threaded rod 27. The inner side of the threaded block 28 is fixedly installed with the outer side of the connecting column 30. A rotating ring 29 is fixedly installed on the surface of the threaded rod 27 and inside the threaded block 28.

[0064] Two different threads are provided on both sides of the surface of the threaded rod 27. These two threads are compatible with the threaded blocks 28 sleeved on both sides of the surface of the threaded rod 27. Therefore, the rotation of the threaded rod 27 can cause the threaded blocks 28 sleeved on both sides of its surface to move in opposite directions. At the same time, the movement of the threaded blocks 28 can drive the connecting post 30 to move. The connecting post 30 moves inside the communication port 24. The mutual cooperation between the communication port 24 and the connecting post 30 can improve the stability of the movement of the fixed ring 25.

[0065] The working principle of the PCB connector provided by this invention is as follows:

[0066] When it is necessary to adjust the elastic deformation force of the spring during operation, the rotating ring can be manually rotated. The rotation of the rotating ring 29 drives the threaded rod 27 to rotate, and the rotation of the threaded rod 27 drives the threaded blocks 28 sleeved on both sides of its surface to move in opposite directions. The movement of the threaded blocks 28 changes the movement of the connecting column 30, and the movement of the connecting column 30 drives the fixing ring 25.

[0067] This causes the retaining ring 25 to move on the surface of the slide rod 6, thereby changing the working spacing between the retaining rings 25. As a result, the spring is compressed by force, and then when the related structure moves and the spring is compressed in the opposite direction, the spring can exert a different force to push the related structure in the opposite direction.

[0068] Compared with related technologies, the PCB connector provided by the present invention has the following advantages:

[0069] The interplay between the connecting port 24, fixing ring 25, mounting block 26, threaded rod 27, threaded block 28, rotating ring 29, connecting column 30, and other structures allows for adjustment of the elastic deformation force of the spring when needed, thereby improving the stability of the related structures in later operation. Furthermore, the operation method and steps are simple and convenient.

[0070] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
