[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figure 1-7 , the present utility model provides a technical solution:

[0031] A circuit board testing and fixing bracket includes a stainless steel base 1. Inside the stainless steel base 1, a PEEK plastic plate 2 is fixedly connected. On the top of the PEEK plastic plate 2, there is a circuit board body 4. It further includes:

[0032] A clamping assembly, which is located on the outer surface of the PEEK plastic plate 2 and is used to fix the circuit board body 4 on the PEEK plastic plate 2 for facilitating its testing;

[0033] A plug-in assembly, which is located on the outer surface of the stainless steel base 1 and is used to increase the number of layers of the stainless steel base 1 and can be further used for the detection of multiple groups of circuit board bodies 4. The circuit board body 4 is used to be fixed on the PEEK plastic plate 2.

[0034] Furthermore, the number of clamping assemblies is multiple. The clamping assembly includes a plug-in hole 5, a bolt 13, a connecting block 14, and a clamping block 15. On the outer surface of the PEEK plastic plate 2, a plurality of equally spaced plug-in holes 5 are opened. Inside the plug-in hole 5, a bolt 13 is inserted. On the outer surface of the bolt 13, a clamping block 15 is fixedly connected. A connecting block 14 is threadedly sleeved on the outer surface of the bolt 13. The connecting block 14 is located on the top of the PEEK plastic plate 2 and below the clamping block 15. Both the connecting block 14 and the clamping block 15 are made of PEEK material. After the bolt 13 passes through the plug-in hole 5, by rotating the bolt 13, the connecting block 14 moves upward along the bolt 13 until the connecting block 14 is in close contact with the surface of the PEEK plastic plate 2, while the clamping block 15 is located above the circuit board body 4, forming an upper and lower clamping structure.

[0035] Furthermore, the circuit board body 4 is located between the connecting block 14 and the clamping block 15. By continuously rotating the bolt 13, the clamping force between the connecting block 14 and the clamping block 15 increases, thereby firmly fixing the circuit board body 4 on the PEEK plastic plate 2.

[0036] Further, connection holes 11 with the same structure are provided at the four corners of the stainless steel base 1. Support rods 3 are inserted into the interiors of the four connection holes 11. Limiting rings 6 are fixedly connected to the outer surfaces of the four support rods 3. The limiting rings 6 are located at the bottoms of the corresponding stainless steel bases 1 and are in movable contact. The support rods 3 are hollow. A limiting ring 6 is fixed to the outer surface of each support rod 3. The limiting ring 6 is in movable contact with the bottom of the stainless steel base 1, playing a positioning and limiting role to increase the number of layers of the stainless steel base 1.

[0037] Further, the insertion assembly includes connection columns 7, clamping columns 8, and springs 10. Connection columns 7 are fixedly connected to the tops of the four support rods 3. Two symmetrically distributed springs 10 are elastically connected to the interiors of the connection columns 7. Two symmetrically distributed clamping columns 8 are movably connected to the interiors of the connection columns 7. The springs 10 are located inside the corresponding clamping columns 8. When the connection columns 7 pass through the connection holes 11 of the stainless steel base 1, the springs 10 are compressed, pushing the clamping columns 8 to move into the connection columns 7. When there is no compression force after passing through the connection holes 11, the two clamping columns 8 move outwards.

[0038] Further, clamping holes 9 are provided on the outer surfaces of the four support rods 3. The two clamping columns 8 are clamped with the corresponding clamping holes 9. The two clamping columns 8 movably penetrate through the corresponding connection holes 11 until the clamping columns 8 are aligned with the clamping holes 9 on the outer surfaces of the support rods 3 and are clamped in, so that the support rods 3 are fixed on the stainless steel base 1.

[0039] Further, a reinforcing plate 12 is fixedly connected to the bottom of the stainless steel base 1. The reinforcing plate 12 is arranged in a "field" - shaped structure. The PEEK plastic plate 2 is fixedly connected to the reinforcing plate 12. The reinforcing plate 12 not only enhances the overall structural strength of the base but also ensures the stable fixation of the PEEK plastic plate 2.

[0040] Working principle: When the staff needs to use the circuit board to test the fixing bracket, first place the circuit board body 4 on the top of the PEEK plastic plate 2. Utilize the multiple equally spaced insertion holes 5 on the outer surface of the PEEK plastic plate 2, and insert the bolt 13 into the corresponding insertion hole 5. A clamping block 15 is fixed on the outer surface of the bolt 13. After the bolt 13 passes through the insertion hole 5, by rotating the bolt 13, the connecting block 14 moves upward along the bolt 13 until the connecting block 14 is in close contact with the surface of the PEEK plastic plate 2, while the clamping block 15 is located above the circuit board body 4, forming an upper and lower clamping structure. By continuously rotating the bolt 13, the clamping force between the connecting block 14 and the clamping block 15 increases, thereby firmly fixing the circuit board body 4 on the PEEK plastic plate 2 to ensure that there is no displacement or shaking during the test. When it is necessary to increase the number of detection layers, utilize the connection holes 11 at the four corners of the stainless steel base 1, and insert the support rod 3 into the corresponding connection hole 11. A connection column 7 is fixedly connected to the top of each support rod 3. A spring 10 and a clamping column 8 are provided inside the connection column 7. When the connection column 7 passes through the connection hole 11 of the stainless steel base 1, the spring 10 is compressed, pushing the clamping column 8 to move into the connection column 7. When there is no compression force when passing through the connection hole 11, the two clamping columns 8 move outward. A limit ring 6 is fixed on the outer surface of each support rod 3, and the limit ring 6 is in movable contact with the bottom of the stainless steel base 1, playing a role in positioning and limiting to increase the number of layers of the stainless steel base 1. When it is necessary to increase the number of layers of the stainless steel base 1 again, sleeve the support rod 3 inside the connection column 7. Under the action of extrusion, the spring 10 drives the two clamping columns 8 to move into the connection column 7 until the clamping columns 8 are aligned with and snapped into the clamping holes 9 on the outer surface of the support rod 3, so that the support rod 3 is fixed on the stainless steel base 1, and then connect the stainless steel base 1 again, thereby constructing a multi-layer detection platform to meet the requirement of simultaneously testing different numbers of circuit board bodies 4. The reinforcing plate 12 fixed to the bottom of the stainless steel base 1 is in a "field" - shaped structure, which not only enhances the overall structural strength of the base but also ensures the stable fixation of the PEEK plastic plate 2, preventing deformation or damage caused by long - term use or vibration during the test. PEEK has high temperature resistance and electrical insulation properties.
