[0002] A circuit board is a component used to fix electronic components and realize electrical connections between components. During the production and processing of circuit boards, in order to ensure that the circuit boards with various components soldered on them are in a normal operating state, it is necessary to test the circuit boards to check whether the current, voltage, resistance and other parameters of the circuit boards with various components soldered on them are normal. Generally, a circuit board test bench is used to test the performance of the circuit boards. The circuit board test bench has the function of testing dedicated interfaces for circuits and systems. The circuit boards can be connected through wires, and in conjunction with other test instruments, measurement and control computers, the performance of the circuit boards can be tested through test programs.

[0003] When testing multiple circuit boards on a circuit board test bench, after the test bench is properly prepared for testing, a single circuit board is first fixed in place using clamps. Then, the single circuit board is connected to the test bench using wires. The test is then started and performance testing is performed. After the circuit board test is completed, the tested circuit board is removed, and then other circuit boards are replaced and tested, repeating the above operation. When testing multiple circuit boards, they cannot be arranged and fixed in an orderly manner to achieve simultaneous testing of multiple circuit boards, or after the test of a single circuit board is completed, the wire connector is directly connected to the next circuit board to be tested, thus simplifying the testing process.

[0004] Existing circuit board test benches have the problem of not being able to fix multiple circuit boards side by side for easy testing. Therefore, this application proposes a circuit board test bench. Utility Model Content

The pressure frame 311 has a connecting plate 33 fixedly connected to one end of the mounting plate 3. When the pull plate 31 is moved outward, the pull rod 32 slides and the compression spring 36 is compressed, thereby changing the position of the spacing H to facilitate the placement of the circuit board workpiece A. The sliding assembly includes a fixing strip 34 fixedly connected between the connecting plate 33 and the mounting plate 3, a sliding block 41 slidably sleeved on the outside of the fixing strip 34, a connecting rod 42 connected to the sliding block 41 by a thread, and an insulating pad 43 fixedly connected to the other end of the connecting rod 42. When the spring strip 5 is pushed outward, the spring strip 5 bends, the protrusion 51 leaves the fixing plate 35, and then the sliding block 41 slides vertically along the height direction of the fixing strip 34 to change the size of the spacing F, so that the insulating pad 43 can support the circuit board workpiece A of different sizes.

[0027] In this embodiment, a fixing plate 35 is fixedly connected to the inner side wall of the mounting plate 3, and the fixing plate 35 has a recessed slot 351.

[0028] In this embodiment, a spring bar 5 is fixedly connected to the surface of the sliding block 41 facing the mounting plate 3, and a protrusion 51 embedded in the slot 351 is provided on the other end of the spring bar 5.

[0029] In this embodiment, the slot 351 is rectangular and the protrusion 51 has an isosceles trapezoidal cross-section.

[0030] In this embodiment, the base plate 21 is a "U" shaped structure with right angles at both ends, the mounting plate 3 is an "L" shaped structure, and a recessed movable groove is provided on the side surface of the mounting plate 3 connected to the rotating cylinder 23. One end of the compression spring 36 and the "T" shaped pull rod 32 is located in the movable groove.

[0031] In this embodiment, the pressing frame 311 is a frame structure, and the inner sidewall of the pressing frame 311 is provided with a hand-tightening screw for the locking pull plate 31.

[0032] In this embodiment, the distance between the opposing surfaces of the pressing frame 311 and the mounting plate 3 is the spacing H, the distance between the bottom surface of the sliding block 41 and the opposing surface of the mounting plate 3 is the spacing F, and the distance between the bottom surface of the pressing frame 311 and the mounting plate 3 is 5 mm.

[0033] Working principle and usage process of this utility model:

[0034] After the main body 1 of the test bench is ready for testing and five circuit board workpieces A are tested,

[0035] 1. Rotate the initially tilted retracted state to the vertical state. The rotating cylinder 23 rotates around the fixed shaft 22 to change the angle of the mounting plate 3. There is frictional resistance between the rotating cylinder 23 and the fixed shaft 22. Under the action of frictional resistance, the rotating cylinder 23 and the mounting plate 3 can remain stable.

[0036] 2. Visually estimate the length of the circuit board workpiece A that needs to be measured, and adjust the height of the sliding block 41.

[0037] 3. When adjusting the height of the sliding block 41, first push the spring bar 5 outward, and the spring bar 5 supported by the elastic material bends. At this time, the protrusion 51 leaves the fixed plate 35. Then slide the sliding block 41 vertically along the height direction of the fixed bar 34 to change the size of the spacing F.

[0038] 4. After the sliding block 41 and the insulating pad 43 are in the appropriate position, release the spring bar 5. The protrusion 51 at one end of the reset spring bar 5 is embedded in the fixing plate 35, so that the sliding block 41 and the spring bar 5 are limited. The position of the adjusted insulating pad 43 can support the circuit board workpiece A to be tested. There is frictional resistance between the sliding block 41 and the fixing bar 34. Under the action of frictional resistance, the sliding block 41 remains stable.

[0039] 5. When placing circuit board workpiece A, first move the pull plate 31 outward, the pull rod 32 slides and the compression spring 36 is in a compressed state, thereby changing the position of the spacing H to facilitate the placement of circuit board workpiece A;

[0040] VI. When placing the circuit board workpiece A, one side of the workpiece A is pressed against the mounting plate 3, and the insulating pad 43 supports the back of the workpiece A. When the pull plate 31 is released, the pull rod 32 and the pull plate 31 slide and return to their original position under the elastic force of the compression spring 36. The pressure frame 311 presses against the other side of the workpiece A. By changing the position of the pull plate 31, the size of the spacing H can be controlled on one side, so as to accommodate workpieces A of different widths. Similarly, different workpieces A can be installed on other mounting plates 3.

[0041] 7. After the measurement is completed, remove the circuit board workpiece A, and rotate the rotating cylinder 23 around the fixed shaft 22 to rotate it from the vertical state to the tilted and retracted state.

[0042] In summary: The circuit board test bench has an installation design that fixes five circuit boards side by side. When the pull plate 31 is moved outward, one side of the circuit board workpiece A is pressed against the mounting plate 3, and the insulating pad 43 supports the back of the circuit board workpiece A. The pressure frame 311 on the released pull plate 31 presses against the other side of the circuit board workpiece A. By changing the position of the pull plate 31, the size of the spacing H can be controlled on one side to accommodate circuit board workpieces A of different widths, thus achieving the effect of fixing five circuit boards side by side.

[0043] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
