[0004] The aforementioned device uses a hydraulic push rod to perform insertion and removal tests on the pin header and nut header connectors, which improves the efficiency of the insertion and removal test. According to the instruction manual and the attached drawings, when fixing the pin header and nut header connectors, the operator needs to manually rotate the screw to drive the clamping plate to clamp synchronously. When conducting batch tests, the continuous rotation of the screw is time-consuming and inefficient. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a connector mating force testing device, comprising a slide rail plate symmetrically arranged at one end of a test base, a rotating block arranged at one end of the slide rail plate, and a connecting shell fixedly installed around the outer periphery of the rotating block. A clamping plate is symmetrically slidably connected inside the connecting shell, and a rotating disk is rotatably connected inside the connecting shell. A connecting shaft is symmetrically fixedly installed at one end of the rotating disk. A long groove is formed at one end of the symmetrical clamping plate, and the long groove is adapted to the connecting shaft. An mounting shell is fixedly installed at one end of the connecting shell. A hollow groove is formed inside the mounting shell, and a rotating shaft is rotatably connected inside the hollow groove. The rotating shaft is fixedly installed with the rotating disk.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model eliminates the need for manual rotation of the lead screw. Fixing can be completed simply by pressing, rotating, and releasing the rotating handle. Pressing the handle releases the limit lock, rotating the handle drives the clamping plate to clamp, and releasing the rotating handle automatically locks the connector. The entire process requires no tools, allows for quick operation, significantly reduces the time spent fixing the connector, and effectively reduces the burden of repetitive operations for workers.

[0024] Reference Figures 1 to 5 In this embodiment of the present invention, the connector mating force testing device includes a slide rail 2 symmetrically arranged at one end of the test base 1, a rotating block 3 arranged at one end of the slide rail 2, and a connecting shell 4 fixedly installed around the outer periphery of the rotating block 3. A clamping plate 5 is symmetrically slidably connected inside the connecting shell 4, and a rotating disk 6 is rotatably connected inside the connecting shell 4. A connecting shaft 8 is symmetrically fixedly installed at one end of the rotating disk 6. A long groove 7 is provided at one end of the symmetrical clamping plate 5, and the long groove 7 is adapted to the connecting shaft 8. An mounting shell 9 is fixedly installed at one end of the connecting shell 4, and a hollow groove 13 is provided inside the mounting shell 9. The internal rotating part 13 is connected to a rotating shaft 10, which is fixedly installed with the rotating disk 6. A pressing rod 11 is slidably connected to the outer periphery of the rotating shaft 10. A rotating handle 12 is rotatably connected to one end of the mounting shell 9, and the rotating handle 12 is fixedly installed with the pressing rod 11. A return spring 14 is fixedly installed inside the empty slot 13, and the other end of the return spring 14 is fixedly installed with the pressing rod 11. A limiting gear 16 is fixedly installed inside the empty slot 13, and a limiting gear 15 is fixedly installed on the outer periphery of the pressing rod 11. The tooth groove of the limiting gear 16 is matched with the tooth of the limiting gear 15.

[0025] The above-mentioned scheme employs the following: the test base 1, slide rail 2, rotating block 3, and connecting shell 4 are all prior art referenced in the prior art documents and are not described in detail in this application. The clamping plate 5 is made of wear-resistant alloy material and is symmetrically slidably connected to the inside of the connecting shell 4. The sliding surface is polished to reduce friction. The rotating disk 6 is made of high-strength alloy material and is rotatably connected to the inside of the connecting shell 4 via bearings. The connecting shaft 8 is made of stainless steel and is symmetrically welded to one end of the rotating disk 6 with a smooth surface. A long groove 7 is formed at one end of the clamping plate 5, with smooth groove walls that precisely match the connecting shaft 8. The connecting shaft 8 slides smoothly. The mounting shell 9 is made of the same material as the connecting shell 4 and is welded to one end of the connecting shell 4. The inner wall of the slot 13 is precision ground. The rotating shaft 10 is made of alloy material and is fixed to the rotating disk 6 by a key connection, and is rotatably connected to the slot 13. The pressing rod 11 is made of stainless steel with a chrome-plated surface for rust prevention and is slidably connected to the rotating shaft 10. The rotating handle 12 is made of engineering plastic with a metal core and is fixedly connected to the pressing rod 11. The return spring 14 is made of high-elasticity spring steel with stable elasticity, and its two ends are respectively connected to the inner wall of the slot 13 and the pressing rod 11. Welded, both the first limiting gear 16 and the second limiting gear 15 are made of high-strength alloy steel. The first limiting gear 16 is fixed inside the empty groove 13, and the second limiting gear 15 is fixed to the outer periphery of the pressing rod 11. The teeth of the first limiting gear 16 mesh precisely with the tooth grooves of the second limiting gear 16. The advantage of this structure is that pressing the rotating handle 12 drives the pressing rod 11 to compress the return spring 14, causing the second limiting gear 15 to disengage from the first limiting gear 16. At this time, rotating the rotating handle 12 can drive the rotating disk 6 to rotate through the pressing rod 11 and the rotating shaft 10, and the connecting shaft 8 slides along the long groove 7. The symmetrical clamping plates 5 are moved and pushed to slide synchronously in the opposite direction along the connecting shell 4, so as to clamp or release the workpiece. The operation is flexible. After the rotating handle 12 is released, the return spring 14 pushes the pressing rod 11 to reset, so that the second limit gear 15 and the first limit gear 16 re-mesh, locking the position of the rotating shaft 10 and the rotating disk 6, preventing the clamping plates 5 from loosening due to external force or vibration, and ensuring stable clamping. The cooperation between the connecting shaft 8 and the long groove 7 converts the rotational motion of the rotating disk 6 into the linear clamping action of the clamping plates 5, ensuring high synchronization of the movement of the two sets of clamping plates 5 and uniform distribution of clamping force.

[0026] Reference Figures 1 to 5 The rotating shaft 10 has symmetrical sliding grooves 17 on its outer periphery. The pressing rod 11 has a sliding groove 18 at one end. The sliding rod 19 is symmetrically arranged inside the groove 18 and is adapted to the sliding groove 17. The connecting shell 4 has a guide groove 20 inside. The two sets of clamping plates 5 have guide blocks 21 fixedly installed at one end and are adapted to the guide groove 20. The clamping plate 5 has an anti-slip block 22 fixedly installed at one end.

[0027] The above-mentioned scheme is as follows: the inner wall of the sliding groove 17 symmetrically opened on the outer circumference of the rotating shaft 10 is smooth; the sliding rod 19 (made of stainless steel) is symmetrically welded inside the through groove 18 at one end of the pressing rod 11. The size of the sliding rod 19 is precisely matched with the sliding groove 17, and the sliding is smooth without jamming. The inner wall of the guide groove 20 inside the connecting shell 4 is smooth; the guide block 21 welded to one end of the two sets of clamping plates 5 is matched with the guide groove 20 to ensure stable sliding trajectory; the anti-slip block 22 is made of high-hardness rubber (with anti-slip texture on the surface) and is fixed to one end of the clamping plate 5 by adhesive bonding, which has a good coefficient of friction and buffering performance. The advantage of this structure is that when the pressing rod 11 slides along the rotating shaft 10, the sliding rod... 19 moves synchronously along the sliding groove 17, ensuring the axial sliding freedom of the pressing rod 11 and achieving torque transmission through the cooperation of the two, ensuring that the rotational force of the rotating handle 12 can effectively drive the rotating shaft 10 and the rotating disk 6 to rotate, avoiding slippage that affects clamping adjustment. When the clamping plate 5 slides, the guide block 21 moves along the guide groove 20, restricting the sliding direction of the clamping plate 5 and preventing it from tilting or deviating due to force, ensuring that the two sets of clamping plates 5 always remain parallel, improving the clamping accuracy of the workpiece. The rubber material of the anti-slip block 22 can increase the friction with the workpiece, preventing the workpiece from slipping during clamping, while avoiding hard contact that could scratch the workpiece surface, adapting to the clamping requirements of workpieces of different materials.

[0028] Reference Figures 1 to 5 A support rod 23 is fixedly installed at the bottom of the test base 1, and the support rod 23 is symmetrically fixedly installed at the bottom of the test base 1.

[0029] The above solution is adopted: the support rod 23 is the prior art mentioned in the reference document and is not described in detail in this application.

[0030] The working principle of this utility model is as follows: When fixing the connector, first press the rotating handle 12 at one end of the mounting shell 9, which drives the pressing rod 11 fixed thereto to slide along the outer circumference of the rotating shaft 10. The sliding rod 19 in the through groove 18 at one end of the pressing rod 11 is adapted to the sliding groove 17 on the outer circumference of the rotating shaft 10 to ensure smooth sliding. At the same time, the pressing rod 11 squeezes the return spring 14 inside the empty groove 13, causing the limiting gear 15 on the outer circumference of the pressing rod 11 to disengage from the tooth groove of the limiting gear 16 in the empty groove 13, thus releasing the rotation lock on the rotating shaft 10. Place the connector between the two sets of clamping plates 5 inside the connecting shell 4, and rotate the rotating handle 12. Through the cooperation of the sliding rod 19 and the sliding groove 17, the rotating shaft 10 and the rotating disk 6 inside the connecting shell 4 rotate synchronously. The connecting shaft 8 symmetrically fixed at one end of the rotating disk 6 is embedded in one end of the clamping plate 5. Inside the long groove 7, when the rotating disk 6 rotates, the connecting shaft 8 slides along the long groove 7 and exerts a pushing force on the clamping plate 5, causing the two sets of clamping plates 5 to slide along the guide groove 20 inside the connecting shell 4. The guide block 21 at one end of the clamping plate 5 is adapted to the guide groove 20 to ensure that the clamping plate 5 moves linearly until the anti-slip block 22 at one end of the clamping plate 5 is tightly attached to the outer periphery of the connector, thus completing the connector fixing. When the rotating handle 12 is released, the elastic potential energy stored in the return spring 14 is released, causing the pressing rod 11 to reset, so that the second limiting gear 15 re-engages into the tooth groove of the first limiting gear 16, locking the position of the rotating shaft 10 and the rotating disk 6, preventing the clamping plate 5 from loosening. The entire fixing process does not require manual rotation of the screw, but can be completed by only three simple actions: pulling, rotating, and releasing the rotating handle 12. The operation is fast and efficient, greatly shortening the connector fixing time and improving testing efficiency.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
