Detailed Implementation

[0024] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and to facilitate its implementation.

[0025] It should be noted that in the following embodiments, the terms "first," "second," and "third" do not represent an absolute distinction in structure and / or function, nor do they represent the order of execution; they are merely for the convenience of description.

[0026] likeFigures 1 to 5 As shown, the present invention provides a testing fixture for a PCBA (Power Steering Controller Board) of a light commercial vehicle, including a PCBA testing section, a PCBA positioning section, and a base plate for fixing the PCBA testing section and the PCBA positioning section.

[0027] Specifically, such as Figures 1 to 5 As shown, the support column 15 is fixedly mounted on the base plate 17. Bolts pass through the base plate 17 and the support column 15 in sequence, and are then fixedly connected to the PCBA testing unit. Two support columns 15 are provided to support the PCBA testing unit. The two support columns 15 are located on the same straight line parallel to the length direction of the base plate 17.

[0028] like Figures 1 to 5 As shown, the PCBA testing section includes a fixing plate 13 and a testing circuit assembly 12. The fixing plate 13 is located above the base plate 17 and the two are parallel. A support column 15 is sandwiched between the fixing plate 13 and the base plate 17. The fixing plate 13 is provided with a plurality of first positioning holes, and the testing circuit assembly 12 is provided with the same number of positioning pins. The positioning pins are engaged with the first positioning holes on the fixing plate 13 to determine the position of the testing circuit assembly 12 on the fixing plate 13.

[0029] like Figures 1 to 5 As shown, the detection circuit assembly 12 is fastened to the fixing plate 13 by bolts, and multiple bolts are provided.

[0030] like Figures 1 to 5 As shown, a snap fastener 14 is provided on each of the left and right sides of the fixing plate 13. The two snap fasteners 14 are on the same straight line parallel to the length direction of the fixing plate 13. The two snap fasteners 14 cooperate to fasten the PCBA positioning part.

[0031] like Figures 1 to 5 As shown, the PCBA positioning part includes a positioning plate 8 and a single-sided buckle 1. Multiple single-sided buckles 1 are provided. The single-sided buckles 1 can be rotated. By rotating the single-sided buckle 1, the PCBA 2 to be tested on the positioning plate 8 can be locked or released.

[0032] like Figures 1 to 5 As shown, the fixing plate 13 is provided with multiple second positioning holes, and a guide column 10 is provided in each second positioning hole. The positioning plate 8 is located above the fixing plate 13 and the two are parallel. The guide column 10 is set vertically.

[0033] like Figures 1 to 5 As shown, the positioning plate 8 has through-holes at each of its four corners. These holes correspond to the second positioning holes on the fixing plate 13, and the third positioning holes are clearance-fitted with the guide column 10. The positioning plate 8 is fitted onto the guide column 10. The guide column 10 passes through the third positioning holes to ensure that the positioning plate can slide freely along the guide column 10.

[0034] like Figures 1 to 5 As shown, a compression spring 11 is provided between the positioning plate 8 and the fixing plate 13. The compression spring 11 is a cylindrical helical spring and a compression spring. The compression spring 11 is sleeved on the guide column 10. The compression spring 11 applies an upward elastic force to the positioning plate 8 and plays a buffering role during the test.

[0035] The testing of the PCBA (Power Steering Controller Board) for light commercial vehicles includes the following steps:

[0036] 1. Ensure that one side of the buckle 1 is in the loose position;

[0037] 2. Place the PCBA2 to be tested onto the positioning plate 8;

[0038] 3. Rotate the single-sided buckle 1 to lock the PCBA 2 to be tested on the positioning plate 8;

[0039] 4. Manually press down on the PCBA positioning part so that the snap fastener 14 can fasten the positioning plate 8 of the PCBA positioning part, and the compression spring 11 is in a compressed state.

[0040] 5. Once the PCBA2 under test makes contact with the detection circuit assembly 12, the testing of the PCBA2 under test begins;

[0041] 6. After the test is completed, loosen the buckle 14, the clamping spring 11 extends, and pushes the PCBA positioning part upward, separating the PCBA from the test circuit assembly 12;

[0042] 7. Loosen the single-sided buckle 1 and remove the PCBA that has been inspected.

[0043] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
