[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings. It is obvious that the described embodiments are only part of the embodiments of the present invention, but not all of the embodiments.

[0042] Embodiment 1, refer to Figure 1 , a method for detecting crimping connectivity of a high-speed connector is provided, comprising the following steps:

[0043] Step S1, performing an impact test on the crimped component to be tested, and outputting the impact test result, applying a DC voltage to the standard crimped component, and measuring standard parameters of the standard crimped component, wherein the standard parameters include a rated current value.

[0044] Step S2, applying the same DC voltage as step S1 to the crimp to be detected, respectively detecting the signal state and the first detection current value of the crimp to be detected and detecting the corresponding crimp height to be detected, comparing the first detection current value with the rated current value and outputting a first comparison result, establishing a corresponding relationship between the signal state and the first comparison result and the crimp height to be detected.

[0045] Step S3, obtaining the state of the insulation layer and measuring the area of ​​the insulation crimping zone of the crimped piece to be detected, outputting the area of ​​the insulation crimping zone to be detected, and establishing a corresponding relationship between the area of ​​the insulation crimping zone to be detected and the state of the insulation layer.

[0046] Step S4, respectively obtain the connector installation status and detect the second detection current value and detect the corresponding stripping length to be detected and the depth of the cable inserted into the crimping area to be detected, compare the second detection current value and the rated current value and output the second comparison result, establish the corresponding relationship between the connector installation status and the second comparison result and the stripping length to be detected or the depth of the cable inserted into the crimping area to be detected.

[0047] Step S5, integrating step S2 to step S4, outputting a crimping part detection model and testing subsequent crimping parts.

[0048] Step S1 includes the following sub-steps:

[0049] Step S101, performing an impact test on the crimped component to be inspected and obtaining deformation and damage conditions, and performing subsequent tests on the crimped component to be inspected according to the deformation and damage conditions.

[0050] By impact testing the crimped parts to be tested, the vibration and impact conditions that may be encountered in actual applications can be simulated, thereby evaluating the mechanical strength and durability of the crimped parts. The deformation and damage conditions obtained directly reflect the stability of the crimped parts under the action of external forces, ensuring that only crimped parts that meet the basic mechanical strength requirements will enter the next stage of electrical performance testing, effectively avoiding misjudgment due to mechanical structure problems.

[0051] Step S102: applying a rated DC voltage to the standard crimping component and obtaining a rated current value of the standard crimping component.

[0052] Applying rated DC voltage to standard crimping parts and obtaining their rated current value is a key step in establishing a test benchmark. The rated current value of standard crimping parts is an important reference for evaluating whether the electrical performance of the crimping parts to be tested is qualified. It ensures that the voltage conditions in subsequent tests are consistent, making the test results comparable and accurate, and also provides a clear standard for subsequent comparison of the current values ​​of the crimping parts to be tested.

[0053] Step S2 includes the following sub-steps:

[0054] Step S201, the standard parameters also include a standard crimping height. A rated DC voltage is applied to the crimped part to be tested and a signal generator is connected. The signal generator is used to send a signal to the crimped part. The signal state of the crimped part to be tested is detected according to the display result of the oscilloscope. If the signal is interrupted, the current crimping height is detected and output as the first crimping height to be tested. A corresponding relationship between the signal state and the current first crimping height to be tested is established, and the corresponding relationship is that the corresponding crimping height is less than the standard crimping height when the signal is interrupted.

[0055] By simulating the actual signal transmission process, a signal generator is used to send a signal to the crimped parts to be tested, and the signal status is observed with the help of an oscilloscope. If the signal is interrupted, the current crimping height is immediately detected and recorded, which directly reveals the reliability of signal transmission of the crimped parts under specific voltage conditions, especially the relationship with the crimping height. By establishing a corresponding relationship that the corresponding crimping height is less than the standard crimping height when the signal is interrupted, the problem points in the crimping process that may cause signal discontinuity can be quickly located, providing a basis for subsequent improvements.

[0056] Step S202, obtain the current value of the crimped part to be detected and output it as a first detection current value, compare the first detection current value with the rated current value, if the first detection current value is less than the rated current value, detect the current crimping height and output it as a second crimping height to be detected, establish a corresponding relationship between the first detection current value and the second crimping height to be detected, the corresponding relationship is that when the first detection current value is less than the rated current value, the corresponding crimping height is greater than the standard crimping height.

[0057] By directly measuring the current value of the crimped part to be tested under the rated DC voltage and comparing it with the rated current value of the standard crimped part, the electrical connection quality of the crimped part can be evaluated. When the first test current value is less than the rated current value, it means that the crimped part may have poor contact or increased resistance. At this time, the current crimping height is recorded, and the corresponding relationship between the first test current value and the second crimping height to be tested is established, that is, when the first test current value is less than the rated current value, the corresponding crimping height is greater than the standard crimping height, which reveals the relationship between the degradation of electrical performance and the abnormal crimping height, and helps to analyze the root cause of the problem in the crimping process.

[0058] Step S3 includes the following sub-steps:

[0059] Step S301, the standard parameters also include a standard insulation crimping area, observe and obtain the insulation layer status, if the insulation layer is broken, detect the current insulation crimping area, output as the first insulation crimping area to be detected, establish a correspondence between the current insulation layer status and the first insulation crimping area to be detected, the corresponding relationship is that when the insulation layer is broken, the corresponding insulation crimping area is smaller than the standard insulation crimping area.

[0060] By observing and obtaining the state of the insulation layer, especially detecting the cracks in the insulation layer, potential problems with the insulation performance can be discovered in a timely manner. When the insulation layer is cracked, the current insulation crimping area is recorded and output, and compared with the standard insulation crimping area. A clear correspondence between the insulation layer state and the insulation crimping area is established, which helps to quickly identify the insulation area reduction problem caused by insulation layer cracks, thereby evaluating its impact on electrical insulation performance, providing data support for subsequent repairs or replacements, and ensuring the overall safety and reliability of high-speed connectors.

[0061] Step S302, if the insulation layer falls off, detect the current insulation crimping area area, output it as the second insulation crimping area area to be detected, establish a corresponding relationship between the current insulation layer state and the second insulation crimping area area to be detected, and the corresponding relationship is that when the insulation layer falls off, the corresponding insulation crimping area area is larger than the standard insulation crimping area area.

[0062] In the case of insulation layer shedding, by detecting and outputting the current insulation crimping area and comparing it with the standard value, another form of insulation performance deterioration is further revealed. By establishing a corresponding relationship between the increase in the insulation crimping area when the insulation layer falls off, it can be clearly understood that the insulation layer shedding not only destroys the original insulation structure, but may also lead to an increase in the exposed conductor area, thereby increasing the risk of electrical short circuits. This is crucial for formulating effective preventive measures and emergency response plans, and helps to improve the overall safety and stability of the electrical system of new energy vehicles.

[0063] Step S4 includes the following sub-steps:

[0064] Step S401, the standard parameters also include the depth of the standard cable inserted into the crimping area, and the connector installation status is obtained. If the connector is not fully in place, the depth of the cable inserted into the crimping area to be detected is detected, and a corresponding relationship between the connector installation status and the depth of the cable inserted into the crimping area to be detected is established. The corresponding relationship is that when the connector is not fully in place, the depth of the corresponding cable inserted into the crimping area to be detected is greater than the depth of the standard cable inserted into the crimping area.

[0065] By detecting the installation status of the connector, especially when the connector is not fully in place, potential problems in the installation process can be discovered in time. When the connector is not fully in place, the depth of the cable inserted into the crimping area to be detected will be greater than the depth of the standard cable inserted into the crimping area. By establishing a corresponding relationship between the connector installation status and the cable insertion depth, poor contact problems caused by improper installation can be clearly identified. This not only helps to discover and correct errors in time during the manufacturing process, but also avoids electrical performance degradation or failures caused by installation problems, thereby improving the overall quality and reliability of the product.

[0066] Step S402, the standard parameters also include a standard stripping length, measuring the current value of the crimped part to be detected and outputting it as a second detection current value, comparing the second detection current value with the rated current value, if the second detection current value is less than the rated current value, detecting the current stripping length and outputting it as the stripping length to be detected, and establishing a corresponding relationship between the second detection current value and the stripping length to be detected, wherein the corresponding relationship is that when the second detection current value is less than the rated current value, the corresponding stripping length is less than the standard stripping length.

[0067] By measuring the current value of the crimped part to be tested and comparing it with the rated current value, the influence of the stripping length on the electrical connection performance can be evaluated. When the second detection current value is less than the rated current value, it indicates that the electrical connection may have problems with poor contact or increased resistance. At this time, the current stripping length is detected and output, and a corresponding relationship between the second detection current value and the stripping length is established. This can reveal that insufficient stripping length is an important factor leading to the degradation of electrical performance, which helps to optimize the stripping process parameters and ensure that the stripping length meets the standard requirements, thereby improving the stability and reliability of the electrical connection.

[0068] In terms of overall effect, through a series of detailed and scientific testing steps, the crimping connectivity of the high-speed connector is comprehensively evaluated to ensure the stability and safety of the electrical system of new energy vehicles. The mechanical strength, electrical performance, insulation performance, and installation quality are combined for multi-dimensional testing, covering all possible problems of high-speed connectors. By establishing the corresponding relationship between parameters including signal status, current value, insulation layer status, installation status, and crimping height and stripping length, the specific links and causes of the problem can be accurately located, providing strong data support for subsequent problem solving. The use of standardized test procedures and parameters improves the efficiency and accuracy of testing. The automated or semi-automated test system further reduces human errors and ensures the reliability and consistency of the test results. Through the feedback of the test results, the deficiencies and potential problems in the production process can be discovered in time, providing a basis for the optimization and improvement of the production process, which helps to improve the overall quality and reliability of the product, reduce the defective rate, and improve production efficiency. Comprehensive crimping connectivity testing ensures the stable operation of high-speed connectors in the electrical system of new energy vehicles, avoids electrical failures and safety hazards caused by poor contact, insulation failure or improper installation, and protects the life and property of drivers and passengers.

[0069] Example 2, refer to Figure 2 , provides a high-speed connector crimping connectivity detection system, including an initial inspection and standard setting module, a defect detection module and a model generation module:

[0070] The initial inspection and standard setting module is used to test the impact resistance of the crimped parts to be inspected and obtain the standard parameters of the standard crimped parts.

[0071] The defect detection module is used to test the defects of the crimped parts to be detected under different surface conditions or electrical conditions and output a number of corresponding relationships.

[0072] The model generation module is used to integrate several corresponding relationships into a crimping detection model and test subsequent crimpings.

[0073] The initial inspection and standard setting module includes an impact test unit and a standard data acquisition unit, where:

[0074] The impact test unit is used to perform impact tests on the crimped parts to be tested and obtain deformation and damage conditions, and select the crimped parts to be tested with qualified deformation and damage conditions for subsequent testing.

[0075] The impact test unit simulates the physical impact that may be encountered in the actual use environment and conducts strict impact tests on the crimped parts to be tested. The purpose is to evaluate the mechanical strength and durability of the crimped parts and ensure that they can maintain a good connection state under harsh working conditions. By obtaining the deformation and damage of the crimped parts, qualified products that can withstand the impact without serious deformation or damage can be screened out, providing reliable samples for subsequent tests, which not only helps to improve the overall quality of the product, but also avoids electrical failures or safety hazards caused by insufficient mechanical strength.

[0076] The standard data acquisition unit is used to apply a rated DC voltage to the standard crimping connection, measure the rated current value of the standard crimping, measure the standard crimping height, standard insulation crimping area, standard cable insertion crimping area depth and standard stripping length of the standard crimping, generate and store standard parameters.

[0077] The standard data acquisition unit is the key to ensuring the accuracy and consistency of detection. By applying the rated DC voltage to the standard crimping parts and measuring their rated current values, the electrical performance parameters of the crimping parts under normal working conditions can be obtained. At the same time, the physical parameters such as the standard crimping height, standard insulation crimping area, standard cable insertion crimping area depth and standard stripping length of the standard crimping parts are measured, which provides an accurate comparison benchmark for the subsequent crimping parts to be tested. The generation and storage of these standard parameters provide solid data support for the entire detection process, ensuring the accuracy and repeatability of the test results. In addition, the standard data acquisition unit also helps to establish and maintain a unified detection standard, and promote quality comparison and evaluation between products from different batches and manufacturers.

[0078] The defect detection module includes a crimp height unit, an insulation layer unit, and a cable and stripping unit, where:

[0079] The crimping height unit is used to apply the same DC voltage as the standard data acquisition unit to the crimping part to be tested, connect the signal generator and the oscilloscope and send a signal to the crimping part, detect the signal state of the crimping part to be tested according to the display result of the oscilloscope, if the signal is interrupted, continue to detect the current crimping height, output as the first crimping height to be detected, establish a first corresponding relationship, the first corresponding relationship is that the corresponding crimping height is less than the standard crimping height when the signal is interrupted, measure the current value of the crimping part to be tested, output as the first detection current value, compare the first detection current value with the rated current value, if the first detection current value is less than the rated current value, continue to detect the current crimping height, output as the second crimping height to be detected, establish a second corresponding relationship, the second corresponding relationship is that when the first detection current value is less than the rated current value, the crimping height is greater than the standard crimping height.

[0080] The crimping height unit simulates signal transmission under actual working conditions to test the electrical performance of the crimped parts to be tested, with special attention paid to the impact of the crimping height on the signal status and current value. When the signal is interrupted, it can quickly locate the problem of insufficient crimping height, and provide key data for analyzing the crimping process by outputting the first crimping height to be tested and establishing a first corresponding relationship. At the same time, by comparing the first detection current value with the rated current value, it can also reveal the poor contact problem that may be caused by excessive crimping height. By outputting the second crimping height to be tested and establishing a second corresponding relationship, the relationship between crimping height and electrical performance is further refined.

[0081] The insulation layer unit is used to observe and obtain the state of the insulation layer. If the insulation layer is broken, the current insulation crimping area area is detected and output as the first insulation crimping area area to be detected, and a third corresponding relationship is established. The third corresponding relationship is that when the insulation layer is broken, the corresponding insulation crimping area area is smaller than the standard insulation crimping area area. If the insulation layer falls off, the current insulation crimping area area is detected and output as the second insulation crimping area area to be detected, and a fourth corresponding relationship is established. The fourth corresponding relationship is that when the insulation layer falls off, the corresponding insulation crimping area area is larger than the standard insulation crimping area area.

[0082] The insulation layer unit focuses on evaluating the integrity and performance of the insulation layer, which is crucial to ensuring the safety and stability of the electrical system. By observing and detecting the status of the insulation layer, it can promptly detect potential problems such as insulation layer rupture or shedding. By outputting the area of ​​the first insulation crimping area to be detected and the area of ​​the second insulation crimping area to be detected, the corresponding relationship between the insulation layer rupture and shedding and the insulation crimping area area is established respectively. This not only helps to quickly identify insulation problems, but also provides an important reference for analyzing the causes of insulation layer damage and formulating improvement measures.

[0083] The cable and stripping unit is used to obtain the installation status of the connector. If the connector is not fully in place, the depth of the cable inserted into the crimping area to be detected is obtained, and a fifth corresponding relationship is established. The fifth corresponding relationship is that when the connector is not fully in place, the corresponding cable insertion depth in the crimping area is greater than the standard cable insertion depth in the crimping area. The current value of the crimped part to be detected is measured and output as a second detection current value. The second detection current value and the rated current value are compared. If the second detection current value is less than the rated current value, the current stripping length is detected and a sixth corresponding relationship is established. The sixth corresponding relationship is that when the second detection current value is less than the rated current value, the corresponding stripping length is less than the standard stripping length.

[0084] The cable and stripping unit focuses on the installation status of the connector and the quality of cable processing, and is a key link in ensuring the reliability of electrical connections. By detecting whether the connector is fully in place, it can promptly discover problems with improper installation, and by establishing the fifth correspondence, it emphasizes the risk of the cable being inserted too deep into the crimping area when the connector is not fully in place. In addition, by measuring the current value of the crimped part to be tested and comparing it with the rated current value, it can also reveal poor contact problems that may be caused by insufficient stripping length. By detecting the current stripping length and establishing the sixth correspondence, it provides strong support for optimizing the stripping process and ensuring the quality of electrical connections, and together constitutes a complete framework for evaluating the quality of cables and stripping, which helps to improve the electrical performance and reliability of the overall product.

[0085] The model generation module includes a model integration unit and a test application unit, where:

[0086] The model integration unit is used to integrate the first corresponding relationship, the second corresponding relationship, the third corresponding relationship, the fourth corresponding relationship, the fifth corresponding relationship and the sixth corresponding relationship to generate a crimping detection model.

[0087] The model integration unit systematically integrates the first to sixth corresponding relationships established in the previous detection units to construct a comprehensive and accurate crimping detection model. It not only integrates the various detection standards of crimping parts in electrical performance, mechanical strength, insulation performance and cable processing, but also includes the direct connection between various potential faults and corresponding detection parameters, so that the complex detection process can be simplified and standardized, providing a powerful tool for subsequent fault analysis and quality inspection. Through the crimping detection model, inspectors can quickly and accurately identify problems with crimping parts, and take corresponding measures to adjust and improve them.

[0088] The test application unit is used to collect the fault conditions of each crimped component to be tested and insert them into the crimped component detection model, generate the fault cause and adjust the crimped component to be tested according to the fault cause.

[0089] The test application unit is the practical link in the crimping inspection process. It is responsible for timely and accurately inserting the fault conditions of each crimping to be inspected collected in the actual inspection into the crimping inspection model generated by the model integration unit. It can quickly generate a detailed fault cause analysis report and provide intuitive and comprehensive fault information to the inspectors. At the same time, it also has the function of automatically or manually adjusting the crimping to be inspected according to the cause of the fault, thereby realizing the closed-loop management of the entire chain from inspection to adjustment, greatly improving the inspection efficiency and accuracy, reducing the possibility of human misjudgment and missed judgment, and providing a strong guarantee for the quality control and production optimization of crimping parts.

[0090] Through the collaborative work of various modules, all-round and accurate detection and adjustment of crimped parts are achieved. Integrating the complex correspondence in multiple detection units into an efficient detection model provides a standardized process and basis for detection work, which not only simplifies the detection process, but also ensures the accuracy and reliability of the detection results. It quickly collects and analyzes the fault conditions of the crimped parts to be detected, generates the causes of the faults, and guides the adjustment and optimization of the crimped parts accordingly. It not only improves the detection efficiency, but also significantly reduces the occurrence rate of unqualified products, ensuring the stability and reliability of product quality. In addition, it promotes the continuous improvement of the production process, lays a solid foundation for the automation and intelligent upgrade of the production line, and realizes the effective control and improvement of the quality of crimped parts.
