Detailed implementation method:

[0019] The present invention will be further described below with reference to the accompanying drawings, such as... Figs. 1-2 As shown, this utility model includes a test base 1, a power amplifier positioning component 2 disposed on the test base 1, a test slide 3 slidably connected to the rear of the power amplifier positioning component 2 in a front-to-back direction, and a test power mechanism 4 for driving the test slide 3 to slide. The test slide 3 is provided with a power cord module 5, a test probe module 6, and an RCA plug module 7 sequentially from left to right. The test power mechanism 4 is disposed on the test base 1, and its output end drives and connects to the test slide 3. Compared to the existing method of manually wiring high-power amplifiers for power-on testing, this utility model provides a more efficient and efficient testing method for high-power amplifiers. When the power amplifier is powered on for testing, the high-power amplifier to be tested is placed on the power amplifier positioning component 2. The test slide 3 is driven forward by the test power mechanism 4, and the power cord module 5, test probe module 6, and RCA plug module 7 are respectively connected to the input and output ports of the high-power amplifier for power-on testing. This utility model can replace the previous method of manually connecting wires to test high-power amplifiers. It is not only simpler to operate and can avoid mistesting and retesting due to incorrect wiring, but also improves the overall testing efficiency. Moreover, it does not require touching the wires, making the overall operation safer.

[0020] The power amplifier positioning component 2 includes a front abutment block 21 for positioning the front end of the high-power power amplifier under test, a rear abutment block 22 for positioning the rear end of the high-power power amplifier under test, a left abutment block 23 for positioning the left side of the high-power power amplifier under test, and a right abutment block 24 for positioning the right side of the high-power power amplifier under test.

[0021] The test mount 1 is equipped with two slide rails 8. The output end of the test power mechanism 4 drives the test slide 3 to the middle position of the bottom. The test slide 3 is equipped with sliders 9 on both sides of the bottom. The test slide 3 is slidably connected to the two slide rails 8 through the two sliders 9, which enables the test slide 3 to slide more smoothly. This ensures that the power cord module 5, test probe module 6, and RCA plug module 7 can be better connected to the input and output ports of the high-power amplifier.

[0022] The front end of the test socket 1 is equipped with a start switch 10 and a stop switch 11. Pressing the start switch 10 will enable automatic testing of the high-power amplifier, and pressing the stop switch 11 will stop the test.

[0023] The test probe module 6 includes multiple test probe heads 61. In this embodiment, there are twenty-four test probe heads 61. The twenty-four test probe heads 61 are equally divided into six groups. The test probe heads 61 in each group are arranged side by side in the left-right direction. The four test probe heads 61 in each group are arranged side by side in the left-right direction.

[0024] The RCA plug module 7 includes multiple RCA plugs 71. In this embodiment, there are twenty RCA plugs 71, which are distributed in a 2x10 matrix.

[0025] This utility model also includes a false trigger detection component 12 to prevent testing of a high-power amplifier that is not properly installed. This can be achieved by setting an infrared detection switch on the test socket 1. In this embodiment, the false trigger detection component 12 includes a limit switch 121, which is located next to the right abutment block 24. The limit switch 121 is triggered only when the high-power amplifier to be tested is correctly placed in the amplifier positioning component 2, i.e., the front abutment block 21, the rear abutment block 22, the left abutment block 23, and the right abutment block 24, so that the power-on test can be performed. When the high-power amplifier to be tested is not placed or is misaligned, the limit switch 121 is not triggered, and even if the start switch 10 is pressed, the power-on test will not be performed, thus better preventing false triggering, making the test more reliable, and more practical.

[0026] Working principle:

[0027] The high-power amplifier to be tested is placed on the amplifier positioning component 2. The test slide 3 is driven forward by the test power mechanism 4, and the power cord module 5, test probe module 6, and RCA plug module 7 are respectively connected to the input and output ports of the high-power amplifier for power-on testing. This utility model can replace the previous method of manually connecting wires to test high-power amplifiers. It is not only simpler to operate and can avoid mistesting and retesting due to incorrect wiring, but also improves the overall testing efficiency. Moreover, it does not require touching the wires, making the overall operation safer.
