What is the standard of wire harness terminal crimping? How to inspect and test wire harness terminals?

Wire harness terminal crimping standards are usually industry and application specific, and may vary from one organization to another. The following is an overview of some common harness terminal crimping standards and inspection and testing methods: Standard Specifications: Some common harness terminal crimping standards include those developed by the International Electrotechnical Commission (IEC), the Institute of Electrical and Electronics Engineers (IEEE), and the Society of Automotive Engineers (SAE). These standards usually define the size of the terminal, material, contact pressure, electrical properties and other requirements. Crimping tools: Crimping tools are used to connect wire harness terminals to wires. Common crimping tools include manual crimping pliers, pneumatic crimping machine and hydraulic crimping machine. According to crimping standards, select the appropriate tool and ensure its quality and correct use. Inspection and testing methods: The following are some common inspection and testing methods for wire harness terminals: Visual inspection: Check the appearance of the wire harness terminals to ensure that there is no obvious damage, deformation or looseness. Dimensional measurements: Use the appropriate measuring tools (such as micrometers or calipers) to measure the dimensions of the terminal, and compare with the standard to ensure that it meets the requirements. Crimp force test: Use a force gauge or the built-in force sensor of the crimping machine to measure the pressure applied to the terminal during the crimping process. Compare with standards to ensure that the crimping force is within the specified range. Electrical Performance Test: Use appropriate test equipment (e.g., contact resistance tester) to test the electrical performance of the wire harness terminals, including contact resistance, electrical connection stability, and so on. These are general overviews of common wire harness terminal crimping standards and inspection and testing methods. Specific standards and methods may vary depending on the industry, application and region you are involved in. Therefore, it is recommended to refer to the applicable standards and related documentation to ensure compliance with the desired specifications and requirements.
