What are the design codes and standards for wire harness terminals? What are the specific design elements?

Design codes and standards for wiring harness terminals are typically developed for specific applications and industry standards. The following are some common design elements that can be used as a reference for the design of harness terminals: Size and shape: The size and shape of harness terminals should be designed according to the size and interface requirements of the harness to ensure compatibility with other devices and connectors. Material selection: The material of wire harness terminal shall have good conductivity, corrosion resistance and heat resistance. Common materials include copper, copper alloy, tin, etc. Contact force and contact resistance: The design of wire harness terminal shall consider the magnitude and uniformity of contact force to ensure stable electrical connection and low contact resistance. Installation mode: The installation mode of the harness terminal can include plug-in type, crimping type, welding type, etc., and the appropriate mode shall be selected according to the specific application requirements and installation environment. Identification and marking: Harness terminals shall be clearly identified and marked, including connection direction, polarity, wiring serial number and other information, so as to facilitate correct installation and maintenance. Insulation protection: insulation protection shall be considered in the design of harness terminals to ensure the insulation between the harness and the surrounding environment and prevent short circuit and electrical failure. Anti-vibration and anti-impact performance: the harness terminal shall have sufficient anti-vibration and anti-impact capacity to deal with the vibration and impact in the working environment of vehicles, mechanical equipment, etc. Compliance with relevant standards: The design of wiring harness terminals shall comply with applicable industry standards and specifications, such as ISO 6722 for the automotive industry, UL standards for the electronics industry, etc. It should be noted that the specific harness terminal design elements will vary according to different application fields and industries. Therefore, it is better to refer to the applicable industry standards and specifications when designing the harness terminal to ensure that the safety, reliability and performance of the terminal meet the requirements.
