What is the standard for crimping wire harness terminals? How to inspect and test the wiring harness terminals?

The crimping standards for wire harness terminals are usually determined based on specific industries and applications, and different organizations may have different standards. The following is an overview of some common wire harness terminal crimping standards and inspection methods:
Standard specifications: Some common wire 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 typically define requirements such as terminal size, material, contact pressure, electrical performance, etc.
Crimping tool: Crimping tool is a tool used to connect wire harness terminals to wires. Common crimping tools include manual crimping pliers, pneumatic crimping machines, and hydraulic crimping machines. According to the crimping standards, select appropriate tools and ensure their 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 wiring harness terminals to ensure that there is no obvious damage, deformation, or looseness.
Size measurement: Use appropriate measuring tools (such as micrometers or calipers) to measure the size of the terminal, compare it with the standard, and ensure that it meets the requirements.
Compression 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 the standard to ensure that the crimping force is within the specified range.
Electrical performance testing: Use appropriate testing equipment (such as contact resistance tester) to test the electrical performance of wire harness terminals, including contact resistance, electrical connection stability, etc.
These are an overview of common wire harness terminal crimping standards and inspection methods. The specific standards and methods may vary depending on the industry, application, and region you are involved in. Therefore, in practical applications, it is recommended to refer to applicable standards and relevant documents to ensure compliance with the required specifications and requirements.
