[0002] Electrical threshold testing is a method for determining the minimum stimulus intensity required for a biological or physical system to respond to electrical stimulation.

[0003] With the development of science and technology, space technology has also made significant progress. However, this development also presents unique challenges in detecting the effects of space environment on electronic components. Therefore, micro-discharge threshold detection equipment is used for this purpose. However, traditional micro-discharge testing equipment relies on large vacuum systems, making the equipment bulky and time-consuming. Furthermore, it cannot quickly determine the threshold of components, and it is often inconvenient to replace the components used for testing. If a component does not meet the placement requirements, a significant amount of effort from staff is required to disassemble and replace it. To address these technical problems, we have designed a rapid micro-discharge threshold detection device that can simulate the temperature difference environment of space. Utility Model Content

[0020] Please see Figures 1-5 A rapid detection device for micro-discharge thresholds that can simulate the temperature difference environment of space includes a workbench 1, a detection box 2 fixedly installed on the top of the workbench 1, an anti-interference layer 3 fixedly installed in the inner cavity of the detection box 2, a linear motor 4 fixedly installed on the rear side of the inner cavity of the detection box 2, an RF probe assembly 5 fixedly installed on the front side of the linear motor 4, a photomultiplier tube assembly 6 through-mounted on the top of the inner cavity of the detection box 2, a dust removal frame 9 fixedly installed in the inner cavity of the detection box 2, a temperature control substrate 11 embedded in the bottom of the inner cavity of the detection box 2, a Peltier element 10 fixedly installed on the bottom of the inner cavity of the detection box 2, and a mounting mechanism 12 provided at the bottom of the inner cavity of the detection box 2. The mounting mechanism 12 includes a mounting shell 14, which is fixedly installed at the bottom of the inner cavity of the detection box 2. By setting the linear motor 4, the RF probe assembly 5 can be moved to adjust its position. By setting the anti-interference layer 3, the interference received by the component during detection can be reduced.

[0021] Please see Figure 1 and Figure 3 An installation slider 15 is movably installed in the inner cavity of the mounting housing 14. A placement platform 13 is fixedly connected to the top of the installation slider 15. The Peltier element 10 is electrically connected to the temperature control substrate 11 via wires.

[0022] Please see Figure 3 Both sides of the bottom of the inner cavity of the test box 2 are fixedly installed with fixing plates 16. Springs 17 are fixedly installed on the opposite side of the two fixing plates 16. Connecting pull plates 19 are fixedly installed on the opposite side of the two springs 17. Limiting insert plates 18 are fixedly connected to the opposite side of the two connecting pull plates 19.

[0023] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 Both sides of the test chamber 2 are connected to vacuum exhaust valves 8, and both sides of the test chamber 2 are connected to temperature sensors 7. By setting temperature sensors 7, the temperature inside the equipment can be monitored in real time so as to monitor the test data. By setting vacuum exhaust valves 8, it is easy to connect to a small vacuum pump.

[0024] Please see Figure 1 , Figure 2 and Figure 4 An air pump 21 is fixedly installed on the rear side of the detection box 2. The air inlet of the air pump 21 is connected to a connecting pipe 22, and the front end of the connecting pipe 22 is connected to the dust removal frame 9.

[0025] Please see Figure 4 A vacuum detector 20 is fixedly installed on the rear side of the test box 2, and support legs are fixedly installed at the four corners of the bottom of the workbench 1. By setting up the vacuum detector 20, the vacuum level inside the test box 2 can be detected in real time to avoid leakage.

[0026] Please see Figure 5 The front of the testing box 2 is fixed with a sealed box door 23 by bolts. An observation window is embedded in the front of the sealed box door 23. By setting the observation window, it is convenient for users to observe the equipment testing process.

[0027] In use, the user first replaces the placement stage 13 with the model number of the electronic component to be tested. During replacement, the user first pulls the two limiting plates 18 relative to each other, causing the connecting pull plate 19 to move and release its restriction on the mounting slider 15. Then, the user pulls the placement stage 13, causing the mounting slider 15 to move out of the mounting housing 14. The user then installs the corresponding model placement stage 13 into the mounting housing 14 to place and test electronic components of different specifications and models. During testing, the user operates the equipment via an external controller. Before testing, the user first controls the vacuum pump 21 to clean the dust inside the test chamber 2 through the connecting pipe 22 and the dust removal frame 9, preventing dust from accumulating inside the test chamber 2. At the same time, the user connects the vacuum discharge valve 8 to the vacuum pump to enable vacuum operation. The user also controls the Peltier element 10 and the temperature control board 11 to work with the vacuum pump to simulate the temperature difference environment of space. During testing, the linear motor 4 drives the radio frequency probe assembly 5 to perform multi-band power detection on the electronic components. During testing, the photomultiplier tube assembly 6 also captures micro-discharge light signals in real time to increase the accuracy of equipment testing.

[0028] In summary, this rapid detection device for micro-discharge thresholds, which can simulate the temperature difference environment of space, solves the problems of over-reliance on large vacuum systems, bulky equipment, long testing cycles, inability to quickly determine the threshold of components, and inconvenience in replacing the components for testing, which require a lot of effort from staff during disassembly. It is achieved through the cooperation of the worktable 1, detection box 2, anti-interference layer 3, linear motor 4, RF probe assembly 5, photomultiplier tube assembly 6, temperature sensor 7, vacuum exhaust valve 8, dust removal frame 9, and Peltier element 10.
