[0068] In this step, the electromagnetic interference environment is simulated by introducing a signal interference generator 40, which is intended to evaluate the performance of the connector under test when subjected to external interference. In practical applications, especially in the field of high-density electronic equipment and communications, it is often necessary to work stably in a complex electromagnetic environment. Through this test, the anti-interference ability and signal fidelity of the connector under test can be understood to ensure stable and reliable data transmission.

[0069] S4, using high-speed data to perform transmission test on the connector under test to evaluate the transmission performance of the connector under test in high-frequency signals;

[0070] This step evaluates the transmission performance of the connector under test in high-frequency signals through high-speed data transmission testing; with the development of high-speed communication technology, the performance of connectors in transmitting high-frequency signals has become particularly important. This test focuses on the integrity, stability and transmission efficiency of the signal, including the evaluation of parameters such as signal attenuation, jitter and bit error rate. This step directly reflects the application ability of the connector under test in a high-speed data environment, ensuring the efficiency and accuracy of data communication.

[0071] S5, collects the electrical performance data of the continuous plug-in test, the signal fluctuation data of the anti-interference test, and the transmission performance of the high-speed transmission test, uses data analysis software to conduct a comprehensive analysis, and compares it with industry standards to evaluate the comprehensive performance of the connector under test.

[0072] The use of data analysis software to comprehensively analyze all collected test data and compare them with industry standards is a key step in evaluating the comprehensive performance of the connector to be tested; through comprehensive analysis of the electrical performance data of the continuous plug-in test, the signal fluctuation data of the anti-interference test, and the transmission performance data of the high-speed transmission test, a comprehensive evaluation of the performance of the connector to be tested can be obtained, which can not only help identify the performance advantages and potential deficiencies of the connector to be tested, but also provide a basis for further design optimization and performance improvement. This step reflects a systematic analysis method and is the basis for achieving connector technology innovation and quality improvement.

[0073] The working principle of the present invention is as follows: when working, firstly, an environmental simulation system 10 is set up, and basic test parameters are set for the connector to be tested, which are suitable for the specifications of the connector to be tested. The environmental simulation system 10 is used to repeatedly plug and unplug the connector to be tested under specific working conditions, and the changes in its electrical performance data are monitored in real time, and the electromagnetic interference environment is simulated to perform interference testing on the connector to be tested to measure its signal stability in a non-ideal environment; a high-speed data transmission test is performed to check the performance of the connector to be tested when processing high-frequency signals, and all test data are collected, comprehensively evaluated through data analysis software, and compared with industry standards to obtain comprehensive performance indicators of the connector to be tested; compared with the testing technology in the prior art, the method makes the test results more targeted through the use of the environmental simulation system 10, reflects the test data of the connector to be tested in a specific application environment, and integrates signal interference testing and high-speed transmission testing, which can comprehensively check the performance and reliability of the connector to be tested in various application scenarios, and increase the depth and comprehensiveness of the test.

[0074] In this embodiment, it is specifically explained that step S1 specifically includes:

[0075] S11, selecting an environmental simulation system 10 adapted to a preset test standard, configuring a control unit of the environmental simulation system 10, and formulating a control strategy of the control unit; the control strategy includes periodic temperature change settings and humidity fluctuations within a set time;

[0076] Selecting an appropriate environmental simulation system 10 is a prerequisite for simulating various environmental factors under actual use conditions. Configuring the control unit and setting the control strategy, such as periodic temperature changes and humidity fluctuations, is crucial to simulating changes in the actual working environment to ensure the accuracy and repeatability of the test results.

[0077] S12, according to the design specifications and application requirements of the connector to be tested, determine the environmental condition parameters that the environmental simulation system 10 needs to simulate; for example, if the connector to be tested is used for outdoor communication equipment, it is necessary to simulate high humidity and salt spray environments; if it is used in the automotive field, it is necessary to simulate vibration and extreme temperature changes.

[0078] To ensure that the environmental simulation can accurately reflect the conditions that the connector under test may encounter in its intended application scenario, so that the test is closer to actual application and provides effective information for design and identification of potential problems.

The expected plugging and unplugging times are the plugging and unplugging times that the connector to be tested should withstand under normal use conditions.

[0080] The basic parameters of the test module are set based on the electrical performance requirements of the connector to be tested to ensure that the test can be carried out based on the actual usage of the connector; by setting the voltage level, maximum current load, and expected number of plugging and unplugging cycles, the performance of the connector to be tested within the specified working electrical range and its physical plugging and unplugging durability can be evaluated.

[0084] By running the environment simulation system 10 in the trial operation and calibrating the control strategy of the control unit according to the feedback data, the trial operation can not only verify the function and stability of the system, but also provide a judgment basis for the optimization of the control strategy to ensure the smooth progress of the subsequent formal test.

[0085] S16, prepare test documents, the test documents are used to record the design specifications, preset environmental conditions and levels, and set basic parameters of the connector to be tested.

[0086] Prepare test documents and record all important test design parameters and conditions. This provides clear documentation support for the test process, ensures the transparency and traceability of the test process, and is also conducive to post-test analysis and review and verification.

[0087] In this embodiment, it is specifically described that step S2 specifically includes:

[0088] S21, initializing the environmental simulation system 10, and starting the environmental simulation system 10 according to the set environmental condition parameters to preheat the system until the environmental parameter area is stable;

[0089] This step involves initializing and preheating the environmental simulation system 10 to ensure that the environmental conditions (such as temperature, humidity, etc.) reach a preset stable state before the system starts testing; this is a prerequisite for accurate testing.

[0095] While starting the plug-in test device to perform continuous plug-in tests, using the sensor network 50 to monitor the electrical performance data of the connector to be tested in real time is an important part of evaluating the performance of the connector; the real-time detection and recording of electrical performance data (such as contact resistance, conduction voltage, current carrying capacity) provides a direct basis for analyzing the performance of the connector, and these data reflect the electrical stability and reliability of the connector during continuous use.

[0096] S25, after completing the expected number of plugging and unplugging tests, visually inspect the connector to be tested to evaluate its physical integrity.

[0097] Visual inspection can reveal physical problems such as damage, wear or deformation on the connector surface, which may affect the long-term performance of the connector; this step is an important supplement to the previous test, ensuring that the connector meets the design and use requirements in terms of physical and electrical performance.

[0098] In this embodiment, it is specifically described that step S3 specifically includes:

[0100] This step involves the configuration of high-speed transmission test equipment, including the settings of high-speed signal generators and signal quality analyzers, and is a key step in evaluating the high-frequency signal transmission performance of the connector under test. By setting the range and transmission rate of the high-frequency signal according to the design specifications and application requirements of the connector under test, it is ensured that the test can cover the expected use conditions of the connector under test.

[0102] Connect the connector to be tested to the high-speed transmission test equipment and start the high-speed signal generator to transmit the signal. This step directly simulates the scenario in which the connector to be tested processes high-speed signals in actual applications. The correct execution of this step is crucial to evaluating the performance of the connector to be tested under actual working conditions.

[0103] S33, during the transmission process, the signal attenuation and time jitter of the transmission signal transmitted by the connector under test are monitored in real time by a signal quality analyzer to evaluate the transmission performance;

[0104] During the signal transmission process, the signal quality analyzer is used to monitor and evaluate the signal quality conducted by the connector under test in real time, including key parameters such as signal attenuation and time jitter. This is a direct evaluation of the transmission performance of the connector under test. The measurement results of these parameters directly affect the judgment of the performance of the connector under test, especially in the application environment of high-speed data communication, the stability and accuracy of the signal are very critical performance indicators.

[0105] S34, changing the signal frequency and amplitude of the high-speed signal generator to evaluate the transmission performance of the connector under test under different working parameters.

It can comprehensively evaluate the adaptability and stability of the connector under test to different signal conditions, and provide important data for design optimization and performance improvement. This step demonstrates whether the connector under test can meet the needs of diverse applications, which is conducive to evaluating its overall performance.

[0107] In this embodiment, it is specifically described that step S5 specifically includes:

[0108] S51, collecting electrical performance data of the continuous plug-in test, signal fluctuation data of the anti-interference test, and transmission performance of the high-speed transmission test;

[0109] Collect and integrate key data from different test stages, including electrical performance data from continuous plug-in and unplug tests, signal fluctuation data from anti-interference tests, and transmission performance data from high-speed transmission tests. This process lays the foundation for subsequent data analysis and comprehensive evaluation; by comprehensively collecting data, it can ensure that the evaluation of the connector to be tested is comprehensive and multi-angle, reflecting its actual performance under various conditions.

[0110] S52, importing the collected electrical performance data of the continuous plug-in test, the signal fluctuation data of the anti-interference test, and the transmission performance of the high-speed transmission test into the data analysis software, and performing data cleaning through the data analysis software to exclude erroneous values ​​and abnormal values;

[0111] In this step, the collected data is imported into the data analysis software for preliminary processing, including data cleaning and exclusion of erroneous values ​​and outliers. This is a key step in ensuring the accuracy and reliability of the analysis results. Data cleaning not only improves the quality of the data, but also provides accurate input for subsequent in-depth analysis, avoiding errors that may be caused by erroneous data.

[0112] S53, uses time series analysis to conduct in-depth analysis of electrical performance data, uses signal processing algorithms to conduct signal analysis of signal fluctuation data, and uses performance degradation curves to conduct performance analysis of transmission performance;

[0113] It should be noted that time series analysis is mainly used to evaluate the changing trends and patterns of electrical performance data, and can reveal the stability and possible periodic changes of the electrical performance of the connector under test during long-term operation. Signal processing algorithm analysis focuses on signal fluctuation data, and evaluates the signal integrity and anti-interference ability of the connector under test in unstable environments such as electromagnetic interference by analyzing the amplitude, frequency and waveform changes of the signal. Performance degradation curve analysis focuses on the long-term changes in transmission performance, especially in high-speed data transmission tests. The degradation curve depicts the possible decline in performance of the connector during continuous use, thereby predicting its life and reliability.

[0114] By using time series analysis, signal processing algorithms, and performance degradation curves to conduct specialized in-depth analysis of different types of data, this step can reveal the changing trends in the electrical performance, signal stability, and performance of the connector under test during long-term use; these in-depth analysis methods make the interpretation of the data more detailed and accurate, providing a scientific basis for evaluating the performance of the connector under test and formulating improvement measures.

This step can effectively point out the outstanding performance of the connector and the areas that need improvement, which is directly helpful for actual product improvement and market positioning.

[0121] The comprehensive performance evaluation report includes not only the preliminary performance conclusions based on various tests and analyses, but also the secondary evaluation results compared with industry standards. A comprehensive evaluation report can provide in-depth insights for the R&D team and related personnel, and serve as a basis for product improvement suggestions, thus promoting the entire product development process from design to application.

[0122] In this embodiment, it is further explained that after step S5, the following steps are further included:
