Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] This application provides a signal processing board insertion and removal test fixture, mainly to solve the problems of the prior art, and provides the following technical solution, which will be combined with the following... Figures 1-4 Please provide a detailed explanation:

[0025] A signal processing board insertion / removal test fixture, comprising:

[0026] An inverted square base 1, wherein an inverted square plate 2 is fixedly provided at equal intervals on the inner bottom side of the inverted square base 1;

[0027] The support platform 3 is fixedly installed in the middle of the U-shaped plate 2, and the signal processing board is placed on top of the support platform 3;

[0028] A clamping mechanism 4 is disposed on the upper side of the U-shaped plate 2. The clamping mechanism 4 is used to clamp and fix the signal processing board. The clamping mechanism 4 includes a rectangular frame 401. A rectangular notch is constructed on the upper side of one side of the U-shaped plate 2, and an installation rod 402 is rotatably connected inside the rectangular notch. Connecting plates 403 are fixed on both sides of the installation rod 402. A torsion spring 404 is provided in the middle of the installation rod 402. One end of the torsion spring 404 abuts against the outer wall of the U-shaped plate 2, and the other end abuts against the top of the connecting plate 403. The end of the connecting plate 403 away from the installation rod 402 is connected to the rectangular frame 401. An extension rod 405 is fixed on the side of the rectangular frame 401 away from the connecting plate 403. A strip-shaped notch 201 is constructed on the upper side of the other side of the U-shaped plate 2. The extension rod 405 is slidably embedded in the strip-shaped notch 201. Abutment rods 406 are provided at intervals on both sides of the rectangular frame 401.

[0029] Mounting platform 5 is located on the upper side of the U-shaped base 1. The testing instrument is mounted on the upper side of mounting platform 5, and the position of mounting platform 5 is adjustable.

[0030] Workflow Description:

[0031] The first step is to prepare:

[0032] Adjust the position of mounting platform 5 according to the size of the testing instrument and the testing requirements.

[0033] Step 2: Fix the signal processing board:

[0034] The clamping mechanism 4 clamps and fixes the signal processing board. Pulling the extension rod 405 upwards disengages it from the strip-shaped notch 201, causing the connecting plate 403 to rotate around the rotational connection point between the mounting rod 402 and the U-shaped plate 2. Since one end of the torsion spring 404 in the middle of the mounting rod 402 abuts against the outer wall of the U-shaped plate 2, and the other end abuts against the top of the connecting plate 403, the torsion spring 404 stores force, causing the connecting plate 403 to rotate around the mounting rod 402. This, in turn, causes the rectangular frame 401 to move closer to the direction away from the support platform 3. When the signal processing board is moved, the operator can place it on top of the support platform 3 to ensure that the signal processing board is initially in the test position. Then, the operator releases the handle, and under the action of the torsion spring 404, the rectangular frame 401 rotates in the opposite direction. When it approaches the signal processing board, the abutment rods 406 set at intervals on both sides of the rectangular frame 401 contact the signal processing board, thereby achieving a tight clamping and fixing of the signal processing board. This ensures that the signal processing board will not shake or shift due to external factors during the test, thus guaranteeing the accuracy and stability of the test.

[0035] Step 3, Test Operation:

[0036] Connect the test instrument to the signal processing board to ensure smooth signal transmission.

[0037] This signal processing board insertion and removal test fixture, with its clamping mechanism 4 and movable mounting platform 5, can quickly fix the signal processing board and adjust the position of the test instrument, ensuring the absolute stability of the signal processing board during testing. This avoids the slight displacement or shaking caused by traditional finger pressing methods, thus greatly improving the accuracy and reliability of the test results. At the same time, it eliminates the need for operators to wear gloves for extended periods of time for tedious pressing operations, greatly improving testing efficiency, and is especially suitable for large-scale production testing.

[0038] like Figure 3 As shown, in some embodiments, the abutment rod 406 and the rectangular frame 401 are connected by a thread. A rubber ball 407 is fixed at one end of the abutment rod 406 inside the rectangular frame 401. More specifically, the threaded connection allows for adjustment of the length of the abutment rod 406 extending into the rectangular frame 401 to accommodate signal processing boards of different specifications. When clamping the signal processing board, the rubber ball 407, as the component in direct contact with the signal processing board, plays a role in buffering and protection. The rubber ball 407 can greatly reduce the pressure on the surface of the signal processing board, avoiding deformation or damage to the signal processing board due to excessive clamping force.

[0039] like Figure 3 As shown, in some embodiments, the rectangular frame 401 is slidably fitted onto the outside of the support platform 3. More specifically, this design makes it easier for the rubber ball 407 at the end of the abutment rod 406 to abut against the signal processing board.

[0040] like Figure 4 As shown, in some embodiments, the mounting platform 5 includes guide plates 501 fixed at intervals above the inner wall of the U-shaped base 1. Square tubes 502 are slidably sleeved on the surface of each guide plate 501. A mounting plate 503 is connected between two square tubes 502. A locking bolt 504 is threadedly connected to the top center of one of the square tubes 502. More specifically, by sliding the square tubes 502 on the surface of the guide plates 501 above the inner wall of the U-shaped base 1, the mounting plate 503 is moved, thereby changing the relative position between the test instrument and the signal processing board mounted on the mounting platform 5. After adjustment, the square tubes 502 are fixed by the locking bolt 504 in the middle of the top of the square tubes 502 to ensure the stability of the mounting platform 5 and prevent displacement during testing.

[0041] like Figure 4 As shown, in some embodiments, the mounting plate 503 has a wire-passing hole 5031 in the middle. More specifically, during signal processing board testing, it is necessary to connect various test instruments and power supplies, etc. Multiple cables will start from the test instruments and connect to the corresponding interfaces on the signal processing board. The presence of the wire-passing hole 5031 allows these cables to pass through the mounting plate 503 in an orderly manner, avoiding the cables from being messily tangled inside the fixture. After the cables pass through the wire-passing hole 5031, the test instruments can be reliably connected to the signal processing board.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
