In order to ensure the stability of high-speed connectors, they need to be tested comprehensively and accurately. However, there are some shortcomings in the stability test methods of high-speed connectors in the prior art. First, the existing test methods usually lack systematicity and standardization, and the test processes and conditions vary from person to person, resulting in poor consistency and comparability of the test results. Secondly, most of the existing methods rely on manual operation, with a low degree of automation, low test efficiency, and easy introduction of human errors. Furthermore, existing tests often only focus on the performance of connectors under normal working conditions, ignoring the influence of various abnormal conditions and boundary conditions, making it impossible for the test results to fully reflect the true stability of the connector. Therefore, the accuracy and reliability of the stability test results of high-speed connectors in the prior art are insufficient. Summary of the invention

[0010] The overall idea of ​​the technical solution provided by this application is as follows:

[0011] The embodiment of the present application provides a stability test method for a high-speed connector. First, the stability test requirements are interactively met and a test environment combining physics and simulation is built. Then, the stability test requirements are traversed and failure test logic based on random combination test elements is designed. On this basis, the upper management machine is used to implement automated test management and control, and standardized tests and random abnormal disturbance intervention tests are performed respectively to obtain one-dimensional failure test data and two-dimensional failure test data that fully reflect the performance of the connector. Afterwards, the failure test data and the stability coefficient of the high-speed connector are comprehensively analyzed to obtain quantitative stability test results, thereby improving the accuracy and reliability of the test results.

[0012] After introducing the basic principles of the present application, the non-limiting implementation methods of the present application will be specifically introduced below in conjunction with the drawings in the specification.

[0013] like Figure 1 As shown, an embodiment of the present application provides a stability testing method for a high-speed connector, the method comprising:

[0014] S1: Stability test requirements of interactive high-speed connectors, building a test environment, wherein the test environment includes a physical environment and a simulation environment, and the stability test requirements are determined based on at least mechanical stability, electrical stability and transmission stability.

[0015] Specifically, in order to conduct a comprehensive stability test on high-speed connectors, first of all, the various stability test requirements of high-speed connectors should be interacted and determined, which should at least include three aspects: mechanical stability, electrical stability, and transmission stability. Among them, mechanical stability focuses on the physical structure of the high-speed connector and the reliability of the mechanical connection; electrical stability focuses on the electrical parameters and signal integrity of the connector; and transmission stability focuses on the bit error rate and anti-interference ability of the connector's high-speed data transmission.

[0016] After clarifying the stability test requirements, build the corresponding test environment. The test environment consists of two parts: physical environment and simulation environment. The physical environment refers to the use of actual high-speed connector devices and test equipment for testing to obtain real test data. For some test items that are difficult to monitor or require long-term evaluation, they are implemented through the simulation environment. For example, the test efficiency can be improved by adjusting the simulation time flow rate. The specific method of building the simulation environment will be further explained in the subsequent steps.

[0017] Through interaction, the key requirements for high-speed connector stability testing were determined, and a test environment including physical and simulation environments was built according to the requirements, laying the foundation for subsequent test execution.

[0018] S2: Traverse the stability test requirements, determine the failure test logic based on the test elements and random combinations.

[0019] Specifically, after the test environment is set up, a specific test plan, namely the failure test logic, is designed according to the determined stability test requirements. The so-called failure test refers to examining the stability limit of the connector by simulating various conditions that may cause the connector to fail in stability.

[0020] First, we traverse the requirements of mechanical stability, electrical stability, and transmission stability, and further refine and determine the specific test elements corresponding to each requirement. Test elements are various physical parameters that affect the stability of high-speed connectors, such as vibration frequency, amplitude, temperature, humidity, voltage, current, etc., or some working conditions, such as plug-in and unplug times, transmission rate, etc. After determining the test elements, considering that the failure condition may be the result of the combined effect of multiple factors, a random combination method is used to arrange and combine different test elements to simulate various possible failure situations. In this way, more comprehensive test conditions can be covered. After that, according to the random combination of test elements, the corresponding failure test logic is set. At the same time, the failure test logic clearly specifies the execution steps, condition parameters, timing relationships, judgment criteria, etc. of each test to ensure the repeatability and evaluability of the test process. In actual execution, not all random combinations must be tested, but typical or key combinations can be selected according to the needs and risk level to avoid excessive testing workload.

[0021] By traversing the stability test requirements, determining the test elements and randomly combining them, and setting a comprehensive failure test logic, a specific implementation plan is provided for the stability test of high-speed connectors.

[0022] S3: Based on the failure test logic, configure a host management machine, wherein the host management machine performs automated test control of the physical environment and the simulation environment.

[0023] Specifically, in order to realize the automation and precise control of the stability test of high-speed connectors, a host management machine is introduced. The host management machine is an automated test management device that automatically executes the test process, collects and analyzes test data, and monitors the test status in real time according to the preset failure test logic.

[0024] First, the set failure test logic is converted into a test program that can be recognized and executed by the upper management machine. By traversing the various elements, parameters, processes, etc. in the failure test logic, the upper management machine is configured in detail, such as setting trigger conditions, test parameters, execution order, acquisition variables, judgment thresholds, etc. In the configuration process, the actual needs of the failure test logic are fully considered, such as the priority of the test branch, the timing relationship of the test task, the frequency and accuracy of data acquisition, etc., so that the upper management machine can perform failure tests and collect and analyze test data in real time. After the configuration is completed, the upper management machine can uniformly control the test execution in the physical environment and the simulation environment. For the physical environment, the upper management machine realizes the test action control and data acquisition of the connector through automated test equipment such as manipulators and electrical parameter analyzers; for the simulation environment, the upper management machine realizes the parameter configuration, timing control and data interaction of the simulation process through the simulation interface. Through centralized control, the upper management machine can coordinate the test progress of the physical and simulation environments to ensure the consistency and comparability of the test results.

[0025] Through the configuration of the upper management machine based on the failure test logic, the automated management and control of the high-speed connector stability test is realized, so that the upper management machine can be flexibly configured according to the stability test requirements and failure test logic, and the test execution of the physical environment and the simulation environment can be centrally controlled, providing an efficient, accurate and reliable platform support for the stability test of the high-speed connector.

[0026] S4: Based on the upper management machine, perform standardized test control based on the failure test logic to determine one-dimensional failure test data.

[0027] Specifically, after completing the configuration of the upper management machine, the actual stability test begins. By executing standardized test control based on failure test logic, one-dimensional failure test data of the high-speed connector under normal failure conditions is obtained.

[0028] The upper management machine automatically performs a series of preset test operations according to the configured failure test logic. These test operations are set according to the failure test logic and cover various factors that may affect stability, such as mechanical stress, electrical load, ambient temperature and humidity, plug-in life, etc. Through standardized test control, the stability performance of high-speed connectors under various normal use conditions is comprehensively examined. During the test execution process, the upper management machine controls and monitors the operating status of the physical environment and the simulation environment throughout the process, adjusts the test parameters in real time according to the requirements of the test logic, and synchronously collects various test data, including the electrical parameters of the connector (such as contact resistance, insulation resistance, signal integrity, etc.), mechanical parameters (such as contact pressure, plug-in force, vibration displacement, etc.), environmental parameters (such as temperature, humidity, etc.) and failure information (such as open circuit, short circuit, signal loss, etc.). The upper management machine automatically records and stores the test data according to the preset data format and acquisition frequency, and performs necessary preprocessing, such as data screening, noise filtering, time synchronization, etc., to ensure the integrity and consistency of the data. When all test operations are completed, the upper management computer automatically stops the test and conducts a comprehensive analysis and evaluation of the collected test data to obtain the one-dimensional failure test data of the high-speed connector under standardized test conditions, reflecting the failure characteristics and stability level of the high-speed connector.

[0029] Through standardized test control based on failure test logic, one-dimensional failure test data of high-speed connectors can be obtained under the automatic execution of the upper management machine, laying a data foundation for subsequent stability evaluation.

[0030] S5: Introduce random anomalies, perform disturbance intervention test control based on the upper management machine, and determine two-dimensional failure test data.

[0031] Specifically, in order to further examine the stability of high-speed connectors in complex environments, random anomalies are introduced on the basis of standardized tests to conduct disturbance intervention tests. The so-called random anomalies refer to various emergencies or extreme stresses that may affect the stability of high-speed connectors outside of normal use conditions, such as electromagnetic interference, power surges, mechanical shocks, and temperature changes. Although these abnormal factors have a low probability of occurrence, once they occur, they often pose a serious threat to the stability of high-speed connectors.

[0032] While executing standardized tests, the upper management machine randomly generates abnormal events according to the preset abnormal models and trigger conditions, and superimposes them into the standard test environment to form disturbance intervention. These abnormal events can be achieved by changing the parameters of the physical test environment (such as applying an external electromagnetic field, changing the power supply voltage, etc.), or simulating abnormal signals in a simulation environment (such as injecting random bit errors, simulating impedance mismatch, etc.). The upper management machine accurately controls the type, amplitude, duration and other parameters of the abnormal events to simulate various possible random abnormal situations. Under the test control of disturbance intervention, the upper management machine continues to collect and record various performance parameters and failure information of the high-speed connector to obtain two-dimensional failure test data that reflects the stability performance of the connector under random abnormal conditions. Compared with one-dimensional failure test data, two-dimensional failure test data can better reflect the ability of high-speed connectors to resist external interference and cope with extreme situations.

[0033] By introducing random anomalies, under the disturbance intervention test control of the upper management computer, two-dimensional failure test data reflecting the stability performance of high-speed connectors in complex environments is obtained. Together with the aforementioned one-dimensional failure test data, it constitutes the data basis for comprehensively evaluating the stability level of the connector, providing sufficient basis for the subsequent test result judgment.

[0034] S6: Based on the one-dimensional failure test data and the two-dimensional failure test data, a stability coefficient is calculated based on the failure point, and a stability test result of the high-speed connector is determined by integration.

[0035] Specifically, after obtaining the one-dimensional failure test data and the two-dimensional failure test data of the high-speed connector under standard conditions and random abnormal conditions, these data are comprehensively analyzed and evaluated to obtain the final stability test results.

[0036] First, based on the one-dimensional failure test data and the two-dimensional failure test data, the stability coefficient of the high-speed connector under different failure modes is obtained. The so-called stability coefficient is a quantitative indicator used to measure the ability of the high-speed connector to maintain stable operation under specific stress or abnormal conditions. The key to calculating the stability coefficient is to determine the failure point, that is, the critical condition for the high-speed connector to significantly deteriorate in performance or fail. The determination of the failure point requires comprehensive consideration of various factors that affect the stability of the high-speed connector, including both the threshold value of a single physical quantity (such as voltage, current, temperature, etc.) and the interaction between multiple factors. For example, according to the design requirements, material properties, structural parameters, etc. of the high-speed connector, a series of failure criteria are pre-determined as a scale for stability testing; then, the one-dimensional failure test data and the two-dimensional failure test data are compared with the failure criteria to find the test conditions that trigger each criterion for the first time during the test process as the failure point of the corresponding failure mode.

[0037] After obtaining the failure point of each failure mode, the corresponding stability coefficient can be calculated. Compare the stress level or abnormality degree of failure in the actual test with the preset failure point threshold, and the size of the difference reflects the stability margin of the connector to resist the failure mode. The corresponding stability coefficient is quantitatively characterized by the ratio of the margin value to the standard value, where the standard value is set according to engineering experience or industry standards. After obtaining the stability coefficient under each failure mode, the importance and correlation of different failure modes are comprehensively considered to obtain a quantitative indicator of the overall stability of the high-speed connector. For example, a weighted average is performed on each stability coefficient, where the weight coefficient can be determined based on factors such as the degree of harm and probability of occurrence of the failure mode; or the minimum value can be selected from the stability coefficient of each failure mode as a short board indicator of the stability of the whole machine. Afterwards, the quantitative stability index is combined with the qualitative test results to form the stability test results of the high-speed connector.

[0038] Through comprehensive analysis of one-dimensional failure test data and two-dimensional failure test data and calculation of stability coefficients, the quantitative stability indicators of high-speed connectors under different failure modes are obtained. Combined with qualitative analysis, comprehensive stability test results are given to accurately judge the stability of high-speed connectors.

[0039] Furthermore, the embodiment of the present application also includes:

[0040] Traversing the stability test requirements and determining the simulation test part;

[0041] Identify the simulation test part and determine simulation environment elements, wherein the simulation environment elements are determined based on the connection circuit, software system and external environment of the high-speed connector;

[0042] The test construction data of the high-speed connector is interacted, the simulation environment elements are traversed, data screening and feature transformation are performed, and the simulation environment is constructed.

[0043] In a preferred embodiment, in order to realize the construction of the simulation environment in the stability test of the high-speed connector, firstly, in the stability test requirements, the part suitable for the simulation test is identified. By traversing various requirements such as mechanical stability, electrical stability, transmission stability, etc., comprehensively considering the feasibility, economy, risk and other factors of the test, the test items with simulation advantages and necessity are screened out, and the simulation test part is obtained as the basis for the subsequent simulation environment construction. Among them, the determination of the simulation test should be based on the stability test requirements to avoid blind simulation and lead to redundancy of the test process. For test requirements involving complex physical processes, long time scales, extreme working conditions, etc., the use of simulation methods can greatly improve the test efficiency and operability; for projects that can be directly tested by physical prototypes, there is no need to simulate. After determining the simulation test part, further analyze the various factors involved in the simulation test and clarify the simulation environment elements. The simulation environment elements are determined based on the connection circuit, software system and external environment of the high-speed connector. Among them, the connection loop refers to the signal transmission path inside the high-speed connector, including contacts, insulators, shielding structures, etc., which are key factors affecting signal integrity and transmission stability; the software system refers to the upper-layer software such as chip drivers and protocol stacks that are compatible with high-speed connectors, which are closely related to the working status and abnormal handling of high-speed connectors; the external environment refers to the temperature, humidity, electromagnetic interference and other environmental conditions of the connector, which have a significant impact on its mechanical and electrical properties. By analyzing the structural composition, working mechanism and application scenarios of the simulation test object, the key factors closely related to stability are identified, and the simulation environment elements are determined in a targeted manner to avoid the simulation range being too large or too small, and to improve the rationality and effectiveness of modeling.

[0044] After the elements of the simulation environment are clarified, the simulation environment construction stage begins. First, various test construction data related to high-speed connector testing are obtained from product design documents, test specifications, simulation software libraries, etc., including device structural parameters, material properties, process conditions, test standards, etc. Then, the determined simulation environment elements are traversed, and the data subsets directly related to each element are screened out from the test construction data to eliminate redundant and invalid information. Next, the screened data is subjected to necessary feature transformation and simplification processing. The so-called feature transformation refers to adjusting the data representation method, sampling accuracy, numerical range, etc. on the premise of retaining the core attributes of the data to meet the modeling requirements of the simulation software, such as coordinate conversion, dimensional normalization, feature dimensionality reduction, etc. After data screening and feature transformation, a virtual prototype model corresponding to the high-speed connector can be built in the simulation software platform according to the composition relationship of the simulation environment elements, reflecting the geometric structure and material properties of the high-speed connector, and also including its internal circuit connection, signal flow, thermal coupling and other multi-physical field information, as well as mathematical descriptions of the software system and environmental factors related to it, forming a simulation environment.

[0045] By traversing and identifying stability test requirements, decomposing environmental factors, and screening and transforming test data, a simulation environment suitable for the stability test of high-speed connectors is built. The structural characteristics, working mechanism and application environment of high-speed connectors are fully considered. While ensuring simulation accuracy and reliability, the modeling cost and complexity are controlled, providing an efficient and reasonable platform support for the virtual stability test of high-speed connectors.

[0046] Further, such as Figure 2 As shown, the embodiment of the present application also includes:

[0047] Traversing the test elements, randomly combining and determining N test groups, wherein each test group contains at least one test element;

[0048] Determine the underlying test logic, wherein the underlying test logic includes a complete test cycle based on a combination of dynamic and static;

[0049] The N test groups are traversed, adaptive adjustments are made based on the underlying test logic, and the failure test logic is integrated and determined.

[0050] In a feasible implementation, in order to comprehensively examine the stability performance of high-speed connectors under various failure modes, a test scheme is designed from multiple angles. First, the test elements are traversed and determined, and several test groups are randomly generated through permutations and combinations to obtain N test groups. Among them, each test group is a subset of the test elements, reflecting a scenario of the stability test of the high-speed connector. The number of test groups N is determined comprehensively based on the number and importance of the test elements, as well as resource constraints such as test time and cost. After determining the N test groups, the test execution logic and process within each test group are further clarified. The underlying test logic is used to guide the specific implementation of each test group. The core of the underlying test logic is a complete dynamic and static combined test cycle. The so-called dynamic and static combination means that within a test cycle, it includes both static tests on high-speed connectors, such as appearance inspection, dimensional measurement, initial electrical parameter testing, etc., and functional tests under dynamic conditions, such as signal integrity testing, mechanical shock testing, high and low temperature cycle testing, etc. Static testing examines the basic performance and initial state of the connector, providing a benchmark for subsequent dynamic testing; dynamic testing fully simulates the actual working state of the connector to assess its stability and reliability under various stress conditions. The complete test cycle combining static and dynamic tests indicates that static tests and dynamic tests are not separated, but organically combined and complementary within a cycle. For example, static tests are performed at the beginning and end of a test cycle to accurately evaluate the changes in the performance of the connector after it is subjected to dynamic stress; necessary static tests can also be inserted in the gaps between dynamic tests to monitor the connector status in real time and detect signs of failure in a timely manner. Through a complete test cycle combining static and dynamic tests, the actual use of high-speed connectors can be simulated to the maximum extent, and their stability level can be comprehensively evaluated to avoid missing potential risks. At the same time, different test groups require different dynamic and static test items and timing arrangements, so the underlying test logic must have a certain degree of universality and flexibility to provide a basic framework for the customized needs of each test group.

[0051] After determining the underlying test logic, further customize and optimize it according to the characteristics of each test group, and finally form the failure test logic. First, traverse N test groups and adaptively adjust the underlying logic to achieve it. The so-called adaptive adjustment refers to the reasonable setting of static test items, dynamic test links, test parameters, timing rhythm, etc. within the underlying logic framework according to the specific conditions of each test group, such as the test elements, failure modes, working conditions, etc., so that the test scheme is adapted and matched with the characteristics of the test object, and the pertinence and effectiveness of the test group are fully utilized. For example, for the test group focusing on mechanical stability evaluation, the test intensity and duration of dynamic stresses such as vibration and impact are increased, while the proportion of electrical parameter testing is correspondingly reduced; for the test group focusing on electrical stability and signal integrity, the electrical performance items such as eye diagram test and crosstalk test under different working conditions are refined; and for the test group assessing environmental adaptability, the range and change gradient of environmental parameters such as temperature and humidity are reasonably set, taking into account both extreme stress and cyclic stress. After completing the adaptive adjustment of each test group, a complete failure test logic can be obtained, covering all aspects of high-speed connector stability testing. It not only includes a unified underlying test framework, but also optimizes for different failure modes and working conditions. It takes into account the comprehensiveness, pertinence and operability of the test, and provides a detailed guidance plan for subsequent automated test execution.

[0052] Based on the random combination of test elements and the complete test cycle combining dynamic and static as the underlying logical framework, the adaptive adjustment of each test group is finally formed to form a comprehensive, reasonable and executable failure test logic. It fully considers the diversity and complexity of high-speed connector failures, adopts the strategy of combined testing and layered design, and realizes the maximum test coverage under the conditions of limited test resources. It also ensures the matching degree between the test scheme and the test object through a flexible customization mechanism, so as to efficiently and accurately evaluate the stability level of high-speed connectors.

[0053] Furthermore, the embodiment of the present application also includes:

[0054] Constructing the basic architecture of the upper management machine, the basic architecture comprising a pre-conditional branch and a post-parallel programmable logic block;

[0055] The failure test logic is traversed, the basic architecture is configured and programmed, and the configured upper management machine is obtained.

[0056] In a feasible implementation, in order to realize the automatic control and real-time monitoring of the stability test of the high-speed connector, an upper management machine is introduced. The upper management machine is the core control unit of the entire test, responsible for the scheduling of the test process, the setting of test parameters, the collection and analysis of test data and other key tasks. In order to meet the specific needs of the stability test, first of all, the basic architecture of the upper management machine is constructed. The basic architecture includes two parts, namely, the pre-conditional branch and the post-parallel programmable logic block. Among them, the conditional branch is located at the front end of the test process, and is mainly responsible for adaptively selecting and triggering different test branches according to the requirements of the test scheme. For example, according to the initial conditions such as the model, batch, and working conditions of the tested high-speed connector, it is determined which test items are to be executed; or according to the test results, the parameters and processes of the subsequent tests are dynamically adjusted to realize the real-time optimization of the test scheme. The parallel programmable logic block is located at the back end of the test process, and is mainly responsible for the specific execution and control of each test branch. It can handle multiple test tasks at the same time and improve the test efficiency; at the same time, it can flexibly adjust the internal processing unit and control strategy according to different test requirements to realize the dynamic configuration of the test function. For example, according to different test items, different functional modules such as data acquisition, parameter analysis, and abnormal diagnosis can be selectively called, and the execution order, priority, and synchronization mode of each functional module can be dynamically adjusted according to actual conditions. The basic architecture including conditional branches and parallel programmable logic blocks not only takes into account the requirements of stability testing for adaptability and flexibility, but also takes into account test efficiency and scalability, providing a reasonable framework for the software and hardware design of the upper management machine.

[0057] After determining the basic architecture of the upper management machine, it is further configured and programmed in detail according to the specific failure test logic. First, the obtained failure test logic is traversed to extract key information, including the type, quantity and execution order of test items, the range and accuracy requirements of test parameters, the judgment threshold and tolerance band, the sampling frequency and data length, as well as possible abnormal situations and their processing solutions. Then, according to this information, the basic architecture of the upper management machine is configured. In the conditional branch, the corresponding branch conditions and trigger logic are set to ensure that the test process can adaptively select the correct execution path; in the parallel programmable logic block, according to the specific test task, the corresponding functional unit, scheduling strategy, synchronization mechanism, etc. are configured, and necessary resource allocation and optimization are performed. After completing the basic architecture configuration, the upper management machine is programmed. For each specific test task, the corresponding test program and control script are written to convert the test plan into an executable code module. After configuration and programming, a host management machine that meets the requirements of high-speed connector stability testing is obtained, so that the predetermined test plan can be accurately, efficiently and reliably executed, and the stability performance of high-speed connectors under various failure modes is comprehensively evaluated.

[0058] By analyzing and traversing the failure test logic based on the basic architecture of conditional branches and parallel programmable logic blocks, the dedicated configuration and programmatic development of the upper management machine are realized, and an automated test control platform that fully matches the stability test requirements is obtained. While ensuring the comprehensiveness and pertinence of the test, it can significantly improve the test efficiency and accuracy, reduce manual operations and random errors, and provide support for the stability analysis of high-speed connectors.

[0059] Furthermore, the embodiment of the present application also includes:

[0060] Determine the element stability threshold and set the element failure point based on stability;

[0061] Obtain the coupling relationship of elements and determine the coupling failure point of the combined elements based on the coupling degree;

[0062] The element failure point and the coupling failure point are used as standard failure points to calculate the stability coefficient of the high-speed connector.

[0063] In a preferred embodiment, in order to quantitatively evaluate the stability level of the high-speed connector, the indicator of stability coefficient is introduced. The calculation of the stability coefficient is based on the failure point, so it is first necessary to determine the element stability threshold for each factor affecting stability as a criterion for judging whether it fails or not. Specifically, a critical value is given for each performance parameter of the high-speed connector. When the parameter value exceeds this critical value, it is considered that the connector has failed in this element, and this critical value is correspondingly defined as the failure point of the element. For example, for the electrical parameter of contact resistance, the critical resistance value for stable operation is calculated based on the rated current and maximum allowable voltage drop of the high-speed connector as the failure point of the contact resistance element.

[0064] At the same time, the stability of high-speed connectors depends not only on a single performance factor, but also on the coupling effect of the interaction and mutual influence between multiple factors. Therefore, on the basis of determining the failure points of each single factor, the coupling relationship between the factors is further considered to obtain the coupling failure point. First, through theoretical analysis, simulation calculation, experimental test and other means, the intrinsic connection and constraint mechanism between different performance factors are revealed, and the coupling between the factors is qualitatively judged. For example, there is a negatively correlated nonlinear relationship between the contact resistance and contact pressure of the high-speed connector, indicating that there is a significant coupling effect between the two. After identifying the element combination with coupling, the strength of the coupling between the elements is quantitatively described, that is, the coupling degree. The higher the coupling degree, the stronger the mutual influence between the elements and the greater the degree of mutual restriction. The coupling degree is quantitatively characterized by mathematical methods such as sensitivity analysis and partial correlation analysis, and can also be qualitatively graded according to experimental data. Afterwards, based on the analysis results of the coupling degree, the coupling failure point under the joint action of the element combination with coupling is given. Unlike the single element failure point, the coupling failure point is not a definite critical value, but a critical area in the multidimensional parameter space. When the parameter value combination falls within this critical region, the high-speed connector is considered to be in a stable state; when the parameter value combination exceeds this region, the connector may fail even if no single parameter has reached its failure point.

[0065] Next, the obtained single-element failure points and coupled failure points are collectively referred to as standard failure points for the stability assessment of high-speed connectors, which comprehensively reflect the stability margin of high-speed connectors under various performance factors and their combinations, and are the basis for calculating the stability coefficient. The basic idea of ​​calculating the stability coefficient is to compare the test data with the standard failure point. The larger the gap between the two, the higher the stability margin of the connector and the larger the stability coefficient. Specifically, the difference (or ratio) between the test parameter value and the corresponding failure point value is taken as the stability margin of the parameter, and then the weighted average (or geometric average) of the stability margin of each parameter is performed to obtain the overall stability coefficient. Among them, the gap between the coupled failure point and the test data point is quantitatively expressed using a distance metric in multidimensional space (such as Euclidean distance, Mahalanobis distance, etc.).

[0066] By determining the standard failure point based on the failure mechanism of high-speed connectors from the two dimensions of single elements and coupling elements, and using the standard failure point as a benchmark, the gap between the test data and the failure point is calculated, and the stability coefficient of the connector under the current working conditions is evaluated. This can specifically reveal the key factors affecting the stability of the connector, identify the weak links, and provide strong data support for the stability test of the high-speed connector.

[0067] Furthermore, the embodiment of the present application also includes:

[0068] For the first failure test logic, traverse the standard failure points and match the first failure point;

[0069] Traversing the one-dimensional failure test data to determine a first test failure point, and traversing the two-dimensional failure test data to determine a second test failure point;

[0070] Based on the difference between the first failure point and the first test failure point, evaluating a first stability coefficient, wherein the first stability coefficient is marked with a positive and negative sign;

[0071] Based on the difference between the first test failure point and the second test failure point, the stability impact relationship of the first abnormality is evaluated.

[0072] In a preferred embodiment, first, for the first failure test logic (such as vibration test), the determined standard failure points are traversed, and the failure point subset related to the logic is matched and recorded as the first failure point. The matching process takes into account the specific content and working condition parameters of the failure test logic, identifies the key physical quantities that have the greatest impact on the stability of the high-speed connector under the logic, and selects the corresponding single element or coupled element failure points according to their physical meaning and numerical characteristics. For example, for the vibration test logic, its first failure point includes vibration displacement amplitude, contact pressure, contact resistance, etc., which jointly determine the stability margin of the high-speed connector under the mechanical vibration environment. Then, the one-dimensional failure test data under the first failure test logic is traversed, and the test points where failure occurs are found as the first test failure points, reflecting the actual failure level of the high-speed connector under the standard conditions of the first failure test logic. Similarly, the two-dimensional failure test data under the first failure test logic is traversed, and the test points where failure occurs are found as the second test failure points, reflecting the actual failure level of the high-speed connector under the abnormal conditions of the first failure test logic. By traversing and analyzing the one-dimensional failure test data and the two-dimensional failure test data under the same test logic, the actual failure points of the high-speed connector under standard conditions and abnormal conditions under this logic are obtained, providing a data basis for the subsequent stability impact analysis.

[0073] After obtaining the first failure point (preset failure point) and the first test failure point (actual failure point under standard conditions) of the first failure test logic, calculate the stability coefficient under this logic and record it as the first stability coefficient. Take the difference between the first failure point and the first test failure point in the key physical quantity as the stability margin of the physical quantity, and then integrate the stability margins of each physical quantity (such as weighted average) to obtain the first stability coefficient. Among them, the stability margin can be positive or negative. When the first test failure point does not reach the first failure point, the margin is positive, indicating that under standard conditions, the high-speed connector still has a certain stability margin; and when the first test failure point exceeds the first failure point, the margin is negative, indicating that under standard conditions, the high-speed connector has exceeded the standard failure. Therefore, the first stability coefficient also has positive and negative signs to distinguish them. The positive and negative signs and numerical values ​​of the first stability coefficient comprehensively reflect the stability margin level of the high-speed connector under the standard conditions of this test logic. By analyzing the first stability coefficient, the reliability and safety margin of the connector design can be judged, and its failure risk under normal use conditions can be evaluated.

[0074] The first test failure point reflects the failure level of the high-speed connector under standard conditions, while the second test failure point reflects its failure level under abnormal conditions. In order to further analyze the impact of abnormal factors on the stability of the high-speed connector under the first failure test logic, the differences between these two types of failure points are compared. Specifically, the difference between the first test failure point and the second test failure point in the physical quantity corresponding to the first abnormality is taken to quantitatively evaluate the change in the failure degree of the high-speed connector after the introduction of the first abnormality, thereby obtaining the stability influence relationship of the first abnormality. Among them, the stability influence relationship includes deterioration type, improvement type, neutral type, etc. The deterioration type means that the second test failure point (failure point under abnormal conditions) significantly exceeds the first test failure point (failure point under standard conditions), indicating that the first abnormality will significantly reduce the stability margin of the high-speed connector; the improvement type means that the second test failure point is better than the first test failure point, indicating that the first abnormality has no negative impact on the stability of the high-speed connector, but may play a certain role in improvement; the neutral type means that the second test failure point is not much different from the first test failure point, indicating that the first abnormality is not closely related to the stability of the high-speed connector and has a weak impact. By comparing and analyzing the differences in failure points under different conditions under the first failure test logic, the influence of the abnormal types represented by the first failure test logic (such as vibration, electromagnetic interference, etc.) on the stability of the high-speed connector is revealed, and the stability of the high-speed connector is tested. Among them, the first abnormality refers to the specific abnormal type introduced by the first failure test logic, and different failure test logics correspond to different abnormal types. By analyzing the stability influence relationship under each failure test logic one by one, the stability performance of the high-speed connector under various abnormal conditions is comprehensively evaluated.

[0075] By calculating and comparing the differences between different failure points, the stability margin level of the high-speed connector under standard conditions and abnormal conditions is evaluated, and the influence of specific abnormal factors on stability is revealed, making the stability analysis more comprehensive and detailed, and improving the reliability of the stability test results of the high-speed connector.

[0076] Furthermore, the embodiment of the present application also includes:

[0077] Obtain N stability coefficients and determine the weight distribution based on the frequency ratio of logical scenarios;

[0078] Traversing the weight distribution, performing weighted calculation on the N stability coefficients, and determining an overall stability coefficient;

[0079] The one-dimensional failure test data, the two-dimensional failure test data, the N stability coefficients, the assembly stability coefficient and the N stability influence relationships are integrated to determine the stability test result.

[0080] In a preferred embodiment, the stability test result of the high-speed connector is obtained by synthesizing the stability analysis results of multiple failure test logics. First, the stability coefficient of each failure test logic is obtained to obtain N stability coefficients. However, in the actual use of the high-speed connector, the frequency of occurrence of different failure scenarios is different, and accordingly, the importance of different test logics is also different. Therefore, when synthesizing the N stability coefficients, the logic scenario frequency ratio of each failure test logic is considered, that is, the relative frequency of occurrence of various failure scenarios. Specifically, by statistically analyzing the historical usage data, failure cases, user feedback, etc. of the high-speed connector, the occurrence frequency of various failure scenarios (such as vibration, electromagnetic interference, thermal shock, etc.) is obtained, and then normalized to obtain a set of frequency ratios as the basis for determining the weights of the N stability coefficients, thereby determining the weight distribution. The higher the frequency ratio of the failure test logic, the greater the weight of its corresponding stability coefficient in the comprehensive evaluation, and vice versa.

[0081] Subsequently, according to the weight distribution determined by the frequency ratio of the logical scenarios, the N stability coefficients are weighted and calculated to obtain the assembly stability coefficient of the high-speed connector. The assembly stability coefficient is a quantitative evaluation index of the overall stability level of the high-speed connector. The larger the value, the better the stability. Among them, the weighted calculation is flexibly selected according to the actual situation, such as the arithmetic mean, geometric mean, harmonic mean, etc. After obtaining the assembly stability coefficient, the one-dimensional failure test data, the two-dimensional failure test data, the N stability coefficients and the N stability influence relationships are combined to form a stability test result, so as to achieve a comprehensive evaluation of the stability of the high-speed connector.

[0082] Furthermore, the embodiment of the present application also includes:

[0083] Identify the positive and negative signs of the stability coefficient, perform binarization processing on it, and determine the binary result;

[0084] The binary results are traversed, and a stability imbalance warning is issued for negative binary results.

[0085] In a preferred embodiment, after the stability test result of the high-speed connector is determined, binarization processing and imbalance warning analysis are further performed on various stability coefficients obtained from the test.

[0086] First, identify the positive and negative signs of each stability coefficient. The positive sign indicates that the actual failure point of the high-speed connector under the corresponding failure test logic is better than the preset failure point, and there is still a certain stability margin; the negative sign indicates that the actual failure point has exceeded the preset failure point, an over-standard failure has occurred, and there is a risk of stability. Then, the stability coefficient is binarized according to the positive and negative signs to obtain a binary result. Specifically, a critical value (such as 0) is set, and the stability coefficient greater than or equal to the critical value is marked as 1, representing stability; the stability coefficient less than the critical value is marked as 0, representing instability. In this way, the stability coefficient is converted into a discrete binary result, which more intuitively reflects the pass or fail of the stability of the high-speed connector under each failure test logic. After obtaining the binary result of the stability coefficient, traverse all the binary results and pay attention to the negative results with a value of 0. The negative result means that under the corresponding failure test logic, the stability of the high-speed connector has been unbalanced and there is a certain risk of failure. For this kind of stability imbalance, a stability imbalance warning is issued in time to prompt the tester to pay attention.

[0087] Through the stability imbalance early warning mechanism based on binary results, the risk points of high-speed connector stability can be discovered sensitively and timely, the speed of problem response and continuous improvement can be accelerated, and the pertinence and effectiveness of stability management and control can be improved.
