However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0024] Example

[0025] Referring to Figures 1-4, this embodiment provides a Bluetooth headset PCBA audio testing device, including a test host 1, a sound source module placement box 2, and a testing box 3. The testing box 3 is equipped with an electric telescopic rod 4, and the output end of the electric telescopic rod 4 is equipped with a test probe group 5 protruding into the testing box 3. The front of the testing box 3 has a through opening 31 that communicates with the inner cavity. The left and right sides of the inner wall of the testing box 3 are equipped with slide rails 32 along the horizontal longitudinal direction. A placement plate 6 is movably connected between the two slide rails 32. The top surface of the placement plate 6 has a placement groove 61 located directly below the probe group 5. The front of the placement plate 6 is equipped with a baffle 62 located in the opening 31.

[0026] In this embodiment, the operator uses the baffle 62 to press and pull the placement plate 6 outward via the slide rail 32, causing the placement plate 6 to move outward through the opening 31 towards the outside of the test box 3 until the placement slot 61 on the top surface of the placement plate 6 moves to the outside of the test box 3. Then, the PCBA board to be tested is placed in the placement slot 61, and the placement plate 6 and the baffle 62 are reset. Finally, the electric telescopic rod 4 is activated, which drives the probe group 5 downward until the probe group 5 is close to the PCBA board and the test is completed.

[0027] As an optional implementation, a rubber pad 7 is provided on the outer side of the baffle 62, and the rubber pad 7 contacts the surface of the detection box 3 through the opening 31.

[0028] In this embodiment, the baffle 62 is pushed into the opening 31, so that its rubber pad 7 is in close contact with the surface of the detection box 3 through the opening 31, thereby achieving the effect of restricting the placement plate 6 and preventing the placement plate 6 from easily sliding inside the detection box 3.

[0029] As an optional implementation, a limiting groove 321 is provided on the slide rail 32, and a threaded hole 63 is provided on the surface of the plate 6 near the limiting groove 321, and a bolt 8 is threaded into the threaded hole 63.

[0030] In this embodiment, during the process of applying pressure and pulling the placement plate 6 outward, the bolt 8 slides within the limiting groove 321 of the slide rail 32 until the bolt 8 passes through the limiting groove 321 and contacts the surface of the slide rail 32. Thus, the cooperation between the bolt 8 and the slide rail 32 achieves the restriction effect on the placement plate 6, preventing the worker from accidentally pulling it off during the process of applying pressure and pulling the placement plate 6 outward.

[0031] As an alternative implementation, a portion of the surface of the bolt 8 protrudes above the slide rail 32 via the limiting groove 321.

[0032] In this embodiment, by setting part of the surface of the bolt 8 above the slide rail 32, it is more convenient for the staff to disassemble and assemble the bolt 8 and the placement plate 6 in the later stage, avoiding the inconvenience caused by the bolt 8 being located in the limiting groove 321.

[0033] As an optional implementation, a pressure sensor 9 is installed inside the detection box 3. The pressure sensor 9 is electrically connected to the electric telescopic rod 4. The pressure sensor 9 is located behind the placement plate 6 and is in contact with it.

[0034] In this embodiment, by sliding the placement plate 6 inside the test box 3, the placement plate 6 is brought into contact with the pressure sensor 9, thereby ensuring the positional relationship of the placement plate 6 inside the test box 3 and avoiding the situation where the probe group 5 cannot perform normal testing on the PCBA board due to the placement plate 6 not being fully inserted into the test box 3.

[0035] As an optional implementation, the surface of the baffle 62 is provided with a handle 621, and the surface of the handle 621 is provided with anti-slip texture.

[0036] In this embodiment, the handle 621 makes it easier for staff to pull and adjust the baffle 62 and the placement plate 6.

[0037] As an optional implementation, anti-slip pads 10 are provided on the bottom surface of the test host 1 and near the corners.

[0038] In this embodiment, an anti-slip pad 10 is provided on the bottom surface of the test host 1, which makes the test device more stable when placed on a table or the ground, and avoids the device from easily sliding and becoming unstable when the baffle 62 is pushed into the opening 31.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
