[0050] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0051] like Figures 1-2 As shown, a printed circuit board test fixture is provided according to a first aspect of the embodiments of this application, comprising: a circuit board support assembly 100, the circuit board support assembly 100 being disposed on the ground or a mounting platform; a circuit board fixing assembly 200, the circuit board fixing assembly 200 being connected to the circuit board support assembly 100, the circuit board fixing assembly 200 being used to fix the printed circuit board; a digital display frame 300, the digital display frame 300 being disposed on one side of the circuit board support assembly 100, the digital display frame 300 being used to fix digital display instruments; and a pointer frame 400, the pointer frame 400 being disposed on the other side of the circuit board support assembly 100, the pointer frame 400 being used to fix pointer instruments.

[0052] The printed circuit board test fixture provided in this application includes a circuit board support assembly 100, a circuit board fixing assembly 200, a digital display frame 300, and a pointer frame 400.

[0053] The circuit board support assembly 100 is set on the ground or a mounting platform to provide a mounting base for the other components and to provide support for the printed circuit board.

[0054] The circuit board fixing assembly 200 is disposed on the circuit board support assembly 100 and is used to fix the printed circuit board placed on the circuit board support assembly 100.

[0055] The digital display frame 300 and the pointer frame 400 are located on both sides of the circuit board support assembly 100 and are used to set up the digital display instrument and the pointer instrument.

[0056] In actual use, the digital display instrument is set in the digital display frame 300, the pointer instrument is set in the pointer frame 400, and the printed circuit board is set in the circuit board support assembly 100. The printed circuit board is fixed by the circuit board fixing assembly 200. Then the printed circuit board is tested, and the readings are taken directly from the digital display frame 300 and the pointer frame 400 during the test.

[0057] This technical solution integrates digital and pointer instruments into the test fixture, reducing the relative area required for printed circuit board testing and making it more convenient for operators to take readings, thus effectively improving production efficiency.

[0058] likeFigures 1-2 As shown, the circuit board support assembly 100 includes: a carrier plate 110, which is disposed on the ground or a mounting platform and is used to place printed circuit boards; and a test rack material plate 120, one end of which is disposed on the upper surface of the carrier plate 110.

[0059] In this technical solution, the circuit board support assembly 100 includes a carrier board 110 and a test fixture material board 120.

[0060] The test fixture material board 120 and the carrier board 110 are L-shaped. When testing the printed circuit board, the printed circuit board is placed on the carrier board 110.

[0061] Understandably, in actual use, an embedding slot can be opened on the carrier board 110, and the printed circuit board can be placed into the embedding slot for easier positioning.

[0062] like Figures 1-2 As shown, the circuit board fixing assembly 200 includes: a lifting assembly connected to the carrier plate 110 and the test frame material plate 120; and a pressure plate 210 connected to the lifting end of the lifting assembly. During testing, the pressure plate 210 presses down on the side of the printed circuit board away from the carrier plate 110.

[0063] In this technical solution, the circuit board fixing assembly 200 includes a lifting assembly and a pressure plate 210.

[0064] In actual operation, after the printed circuit board is fixed by the pressure plate 210, tests such as flying probe tests are performed. The pressure plate 210 is raised and lowered by the lifting component. When it is necessary to fix the printed circuit board, the pressure plate 210 is lowered, and when it is necessary to remove or put the printed circuit board in, the pressure plate 210 is raised.

[0065] like Figures 1-2 As shown, the lifting assembly includes: a first fixing plate 220 connected to the test frame material plate 120; a quick clamp 230 connected to the first fixing plate 220, with the lifting end of the quick clamp 230 connected to the pressure plate 210; a guide rail 240, one end of which is disposed on the carrier plate 110; a limiting block 250 disposed at the other end of the guide rail 240; and a first sliding block 260 sleeved and connected to the guide rail 240, which can slide on the guide rail 240, with the pressure plate 210 connected to the first sliding block 260.

[0066] In this technical solution, the lifting assembly includes a first fixed plate 220, a quick clamp 230, a guide rail 240, and a limiting block 250. The first fixed plate 220 provides an installation base for the quick clamp 230. The first fixed plate 220 is mounted on the test frame material plate 120. The quick clamp 230 is mounted on the first fixed plate 220 and has a lever with a first position and a second position. When the lever is in the first position, the telescopic end of the quick clamp 230 is in a raised state; when the lever is in the second position, the telescopic end of the quick clamp 230 is in a lowered state. One end of the guide rail 240 is connected to the carrier plate 110. A first sliding block 260 is slidably connected to the guide rail 240. A pressure plate 210 is connected to the first sliding block 260. The guide rail 240 can push the pressure plate 210 to limit its movement, preventing the pressure plate 210 from rotating or shifting.

[0067] During use, with the lever of the quick clamp 230 in the first position, the printed circuit board is placed in the clamp. Moving the lever from the first position to the second position causes the pressure plate 210 to press down and secure the printed circuit board, allowing testing to proceed.

[0068] like Figures 1-2 As shown, the test frame material plate 120 has several screw holes at different horizontal heights; the first fixing plate 220 is connected to the test frame material plate 120 by locking screws; the first fixing plate 220 is connected to the screw holes at different horizontal positions by locking screws, thereby changing the horizontal height of the quick clamp 230.

[0069] In this technical solution, the range of the quick clamp 230 can be changed by setting the first fixing plate 220 on different screw holes of the test material rack.

[0070] like Figures 1-2 As shown, the digital display frame 300 includes: a first frame, with a square groove in the middle for fixing the digital display instrument; a first telescopic spring rod, the first frame being hollow inside, one end of the first telescopic spring rod being disposed inside the first frame, and at least two first telescopic spring rods being disposed on both sides of the square groove; and two first fixing pieces, each connected to one end of the first telescopic spring rod, with strip-shaped telescopic openings on both sides of the square groove of the first frame, through which the first fixing pieces extend out of the first frame.

[0071] In this technical solution, the above settings provide two retractable first fixing plates on both sides of the square slot. When the instrument to be fixed is smaller than the square slot, the two first fixing plates can press the instrument from both sides and fix it, so that the instrument clip can be adapted to any size instrument within a certain range.

[0072] This setting increases the flexibility of this technical solution.

[0073] like Figures 1-2 As shown, the pointer meter frame 400 includes: a second frame with a circular groove in the middle for fixing the pointer meter; a second telescopic spring rod, the second frame being hollow, one end of the first telescopic spring rod being disposed inside the first frame, and at least two first telescopic spring rods being disposed on both sides of the circular groove; and two second fixing pieces, each connected to one end of the second telescopic spring rod. Arc-shaped telescopic openings are provided on both sides of the circular groove of the second frame, through which the first fixing pieces extend out of the second frame.

[0074] In this technical solution, the above settings provide two retractable second sliding block fixing pieces on both sides of the square slot. When the pointer instrument to be fixed is smaller than the square slot, the two second sliding block fixing pieces can squeeze the pointer instrument from both sides and fix it, so that the pointer clamp can be adapted to pointer instruments of any size within a certain range.

[0075] This setting increases the flexibility of this technical solution.

[0076] like Figures 1-2 As shown, it also includes a sliding component, wherein the digital display frame 300 and the pointer frame 400 are connected to the circuit board support assembly 100 via the sliding component.

[0077] In this technical solution, the test fixture also includes sliding components. It can be understood that there are two sets of sliding components, which are respectively connected to the digital display frame 300 and the pointer frame 400.

[0078] This technical solution allows for arbitrary adjustment of the height of the digital display and pointer instruments during testing. Operators can adjust them to a comfortable angle and lock them in place, improving the ease of use and flexibility of the solution.

[0079] like Figures 1-2 As shown, the sliding assembly includes: a sliding groove disposed on the test frame material plate 120; a second sliding block, one end of which is slidably connected to the sliding groove, and the other end of which is fixedly connected to the digital display frame 300 or the pointer frame 400; and a locking member disposed on the second sliding block, wherein when the locking member is locked, the second sliding block is fixed relative to the sliding groove.

[0080] like Figures 1-2 As shown, it also includes a rotating shaft, and the digital display frame 300 and the pointer frame 400 are connected to the second sliding block via the rotating shaft.

[0081] In this technical solution, the test fixture also includes a rotating shaft. The digital display frame 300 and the pointer frame 400 are both connected to the second sliding block through the rotating shaft. In actual use, not only the height can be adjusted, but also the reading angle can be adjusted, further improving the ease of use of this technical solution.
