End plates 8 are provided at both ends of the fins 2, and a locking plate 9 is fixedly connected to the outer side of the end plates 8. End blocks 10 are fixedly connected to both ends of the end plates 8. An anti-detachment mechanism is provided on the top of the end plates 8. A connecting groove 11 is provided on the outer side of the end blocks 10, and a connecting rod 12 is slidably inserted into the connecting groove 11. The FPGA interface expansion board body 1 is existing technology in the field and has its own expandable function, therefore, it will not be described in detail here.

[0024] In use, the fins 2 are installed and fixed with bolts. The buffer pads 7 are used to absorb vibration energy. The FPGA interface expansion board body 1 is connected to the mounting slot 4. At this time, the heat conduction film 5 conducts heat to the FPGA interface expansion board body 1, and the fins 2 dissipate heat to ensure that the FPGA interface expansion board body 1 is more stable during use. Then, the end plate 8 is clamped to the fixing post 6 through the clamping plate 9 to clamp and fix the FPGA interface expansion board body 1. The connecting rod 12 is inserted into the connecting slot 11 to prevent the end plate 8 from falling off, ensuring the stable installation of the FPGA interface expansion board body 1. The clamping and fixing of the end plate 8 to the FPGA interface expansion board body 1 makes it easy to disassemble and operate during subsequent maintenance of the FPGA interface expansion board body 1.

[0025] Please see Figure 1 - Figure 4 The FPGA interface expansion board body 1 is slidably inserted into the mounting slot 4. The buffer pad 7 is made of rubber. The connecting slot 11 is a T-shaped structure. The connecting rod 12 is an I-shaped structure. A C-shaped groove is opened on the outer side of the card plate 9. The card plate 9 is engaged with the fixing post 6 through the C-shaped groove. The outer side of the card plate 9 is in contact with the side of the FPGA interface expansion board body 1. The outer wall of the FPGA interface expansion board body 1 is in contact with the inner wall of the mounting slot 4.

[0026] To better secure the connecting wire harness, the anti-detachment mechanism includes a protrusion 13, a first anti-detachment bracket 14, a second anti-detachment bracket 15, a buckle 16, a wire-passing groove 17, a docking groove 19, a docking rod 20, and a pressure block 21. The protrusion 13 is fixedly connected to the top of the end plate 8. The first anti-detachment bracket 14 is located on the outside of the end plate 8, and the second anti-detachment bracket 15 is located on the outside of the end plate 8. Buckles 16 are fixedly connected to the outside of both the first and second anti-detachment brackets 14 and 15. The wire-passing groove 17 is located on the outside of the first and second anti-detachment brackets 14 and 15. The docking groove 19 is located at one end of the first anti-detachment bracket 14. The docking rod 20 is fixedly connected to the end of the second anti-detachment bracket 15. The pressure block 21 is fixedly connected to the ends of the first and second anti-detachment brackets 14 and 15.

[0027] After the connecting cable is connected to the terminal block on the FPGA interface expansion board body 1, the first anti-detachment bracket 14 and the second anti-detachment bracket 15 are connected to the protrusion 13 through the buckle 16, which quickly installs and fixes the first anti-detachment bracket 14 and the second anti-detachment bracket 15. At this time, the docking groove 19 and the docking rod 20 are inserted into each other to achieve the effect of preventing deformation at the connection. One side of the first anti-detachment bracket 14 and the second anti-detachment bracket 15 is attached to the end of the wire harness plug to perform anti-detachment limit treatment on the wire harness plug, so as to prevent the wire harness from being pulled off and ensure the stability of the wire harness connection. At the same time, the bottom of the pressure block 21 is attached to the top of the connecting rod 12 to limit and fix the connecting rod 12, thereby indirectly fixing the end plate 8 for a secondary purpose and further ensuring the installation stability of the end plate 8.

[0028] Please see Figure 1 - Figure 4 The bottom of the pressure block 21 fits against the top of the connecting rod 12. The protrusion 13 has an I-shaped structure. The buckle 16 is snapped into the protrusion 13. The wire groove 17 is through-hole set. The inner wall of the docking groove 19 fits against the outer wall of the docking rod 20.

[0029] The working principle of the above embodiments is as follows:

[0030] During use, the fins 2 are installed and fixed with bolts. The buffer pads 7 are used to absorb vibration energy. The FPGA interface expansion board body 1 is connected to the mounting slot 4. At this time, the heat conduction film 5 is used to conduct heat to the FPGA interface expansion board body 1, and the fins 2 are used to dissipate heat, ensuring that the FPGA interface expansion board body 1 is more stable during use. Then, the end plate 8 is clamped to the fixing post 6 through the clamping plate 9 to clamp and fix the FPGA interface expansion board body 1. The connecting rod 12 is inserted into the connecting slot 11 to prevent the end plate 8 from falling off, ensuring the stable installation of the FPGA interface expansion board body 1. The clamping and fixing of the end plate 8 to the FPGA interface expansion board body 1 makes it easier to disassemble and operate during subsequent maintenance of the FPGA interface expansion board body 1.

[0031] After the connecting cable is connected to the terminal block on the FPGA interface expansion board body 1, the first anti-detachment bracket 14 and the second anti-detachment bracket 15 are connected to the protrusion 13 through the buckle 16, which quickly installs and fixes the first anti-detachment bracket 14 and the second anti-detachment bracket 15. At this time, the docking groove 19 and the docking rod 20 are inserted into each other to achieve the effect of preventing deformation at the connection. One side of the first anti-detachment bracket 14 and the second anti-detachment bracket 15 is attached to the end of the wire harness plug to perform anti-detachment limit treatment on the wire harness plug, so as to prevent the wire harness from being pulled off and ensure the stability of the wire harness connection. At the same time, the bottom of the pressure block 21 is attached to the top of the connecting rod 12 to limit and fix the connecting rod 12, thereby indirectly fixing the end plate 8 for a secondary purpose and further ensuring the installation stability of the end plate 8.
