[0002] VPX boards are widely used in many electronic fields, and their stable performance is crucial for the normal operation of the entire system. In practical applications, VPX boards need to be reliably connected to mating terminals, and crimping is a key operation to achieve this connection. Precise and stable crimping can ensure smooth signal transmission and reliable electrical connections, thereby ensuring the normal operation of VPX boards in complex electronic systems. However, achieving high-quality crimping is not easy and requires specialized tools and precise operations to ensure the accuracy and consistency of crimping.

[0003] Traditional VPX board crimping methods often have many drawbacks. On the one hand, the lack of crimping fixtures specifically designed for the characteristics of VPX boards makes it difficult to accurately position and securely clamp the board during the crimping process, which can easily lead to board positional deviation and affect crimping accuracy. This results in the mating terminals not accurately aligning with the board pins, reducing connection reliability. On the other hand, existing crimping tools are not flexible enough in terms of adjustment, making it difficult to quickly and accurately adjust them according to different VPX board specifications and different crimping requirements. To address these issues, we propose a VPX board crimping fixture to solve the problems mentioned above. Utility Model Content

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This VPX board crimping fixture has a design where one end of a second trapezoidal screw is rotatably connected to the inner wall of the first groove of the base plate, and the other end extends to the outside of the base plate. The outer ring threads on both sides of the screw have opposite directions. The two moving plates have matching threaded holes at their lower parts. When the first rotary knob is rotated to drive the second trapezoidal screw to rotate, the two moving plates can move synchronously towards or away from each other in the first groove.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figures 1-4 A crimping fixture for a VPX board includes a clamping mechanism and a crimping adjustment mechanism. During the VPX board crimping operation, the VPX board body 13 is first placed in a suitable position on the base plate 1. For the clamping mechanism, by rotating the first rotary knob 4, one end of the second trapezoidal screw 12 is rotatably connected to the inner wall of one side of the first groove opened in the base plate 1, and the other end extends through and to the outside of one side of the base plate 1. The outer threads on both sides of the second trapezoidal screw 12 are arranged in opposite directions. The lower parts of the two moving plates 3 are provided with openings that connect with the outer threads on both sides of the second trapezoidal screw 12. The first rotary knob 4 is matched with the threaded hole, so rotating the first rotary knob 4 will drive the second trapezoidal screw 12 to rotate, thereby causing the two moving plates 3 to move closer or further apart in the first groove of the base plate 1. Here, the two moving plates 3 are adjusted to a suitable position so that the limiting fixing plate 2 installed on the side where the two moving plates 3 are close to each other can clamp the VPX card body 13. The lower part of the side where the limiting fixing plate 2 is close to each other is inclined and is provided with a protective pad to avoid damage to the card. Then tighten the fastening nut 6 to fix the position of the second trapezoidal screw 12 and prevent the clamping from loosening.

[0024] For the crimping adjustment mechanism, rotate the end of the first trapezoidal screw 7 located on the outside right side of the base plate 1. One end of the first trapezoidal screw 7 is rotatably connected to the side wall of the sliding block 11 on the left side, and the other end passes through the right sliding block 11 and extends to the outside right side of the base plate 1. The inner walls of the second groove on both sides of the base plate 1 have sliding grooves, and there are matching sliding blocks 11 in the sliding grooves. The two sliding blocks 11 are close to each other, and guide rods 10 that pass through both sides of the moving frame 8 are installed on both sides. The moving frame 8 is located in the second groove and the pad 9 is placed in the frame of the moving frame 8. Therefore, by rotating the second rotary knob 5, the first trapezoidal screw 7 can be rotated, which will further drive the moving frame 8 to move in the second groove, thereby adjusting the position of the pad 9. Since the pad 9 has multiple limiting grooves that match the pin through holes on the VPX board body 13 for connecting the docking terminals, after adjusting the pad 9 to the appropriate position, the docking terminals can be accurately crimped onto the pins of the VPX board body 13.

[0025] Example 2: Please refer to Figures 1-4 When it is necessary to crimp VPX boards of different specifications, the VPX board body 13 is first placed on the base plate 1. For the clamping mechanism, the operator holds the first rotary knob 4, which has anti-slip protrusions on its outer ring for easy rotation. Rotating the first rotary knob 4 drives the second trapezoidal screw 12 to rotate. According to the size of the board, the two moving plates 3 are moved to a suitable distance in the first groove so that the limiting fixing plate 2 can firmly clamp the VPX board body 13.

[0026] For the crimping adjustment mechanism, based on the position of the pin through holes on the VPX board body 13, rotate the end of the first trapezoidal screw 7 located on the outer right side of the base plate 1, so that the moving frame 8 moves in the second groove along the direction of the guide slide rod 10, driving the pad 9 to move. Since the inner wall of the right side of the second groove opened on the base plate 1 has a through hole that extends to the outside of the base plate 1, the first trapezoidal screw 7 moves in the through hole to ensure smooth movement. After accurately aligning the limiting groove on the pad 9 with the pin through holes of the VPX board body 13, stop rotating the second rotary knob 5. Then tighten the fastening nut 6 between the second rotary knob 5 and the base plate 1 to further fix the moving frame 8 and prevent the moving frame 8 from moving, thereby enabling stable crimping of the mating terminals and improving the accuracy of crimping.

[0027] Based on the pin via positions on the first VPX board body 13, rotate the first trapezoidal screw 7 to adjust the position of the pad 9. After completing the crimping of the first board, since the specifications of the boards in the same batch are similar, only the first trapezoidal screw 7 needs to be finely adjusted so that the limiting groove on the pad 9 is accurately aligned with the pin vias of the subsequent VPX board body 13. This allows for rapid batch crimping operations and improves production efficiency.

[0028] For different pin via positions on different VPX board bodies 13, the pad 9 in the movable frame 8 can be replaced with a pad 9 that matches the pin via on the VPX board body 13. This is easy to operate and suitable for crimping various VPX board bodies 13.

[0029] Implementation effect: The second trapezoidal screw 12 is rotatably connected to the inner wall of the first groove of the base plate 1 at one end and extends to the outside of the base plate 1 at the other end. The outer ring threads on both sides are opposite in direction. The two moving plates 3 have matching threaded holes at the bottom. When the first rotary knob 4 is rotated to drive the second trapezoidal screw 12 to rotate, the two moving plates 3 can move synchronously towards or away from each other in the first groove. This allows the limiting fixing plate 2 installed on the moving plate 3 to accurately clamp the VPX card body 13 of different sizes. The inclined shape and protective pad of the lower part of the limiting fixing plate 2 can not only firmly clamp the card, but also avoid damage to the surface of the card, thus improving the versatility and safety of clamping.

[0030] The first trapezoidal screw 7 is rotatably connected at one end to the left sliding block 11 and extends through the right sliding block 11 to the outside of the base plate 1. Combined with the guiding effect of the inner wall groove of the second groove of the base plate 1, the sliding block 11 and the guide rod 10, when the second rotary knob 5 is rotated to drive the first trapezoidal screw 7 to rotate, the moving frame 8 can move precisely in the second groove, thereby adjusting the position of the pad 9. The limiting groove opened on the pad 9 matches the pin through hole of the VPX board body 13, which can make the mating terminal accurately press onto the board pin, improving the accuracy and efficiency of the pressing.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
