The standard for wire harness insertion and extraction force refers to the force requirements used to evaluate the performance of wire harness connection insertion and extraction. The specific standards may vary depending on the industry and application. Here are some common wire harness insertion and extraction force standards:
IPC/WHMA-A-620: This is an international standard for the electronic wiring harness manufacturing industry, jointly developed by IPC (Electronic Industry Alliance) and WHMA (Wiring Harness Manufacturers Association). This standard includes various requirements for wiring harnesses, including requirements for insertion and extraction force.
UL (Underwriters Laboratories) is an internationally recognized independent safety certification organization. The UL standards cover safety requirements for various electrical and electronic products, including standards for wire harness insertion and extraction force.
Below is the UL468A pull test specification, which is very popular in the cable industry.
Automotive industry standards: The automotive industry has a series of standards and specifications, such as ISO 6722, SAE J1128, etc. These standards usually specify the requirements for wire harness insertion and extraction force to ensure the reliability and safety of automotive wire harnesses in use.
Industry internal standards: Different industries and companies may have their own internal standards and specifications for evaluating wire harness insertion and extraction force. These standards may be developed based on practical application requirements and experience summary.
The specific standard for wire harness insertion and extraction force usually defines the following elements:
Testing methods and equipment for insertion and extraction force
Rated value or range of insertion and extraction force
Measurement position and direction of insertion and extraction force
The evaluation criteria for insertion and extraction force, such as judgment through visual, sensory, or specific instruments
It should be noted that specific standards and requirements may vary depending on the industry, product type, and application. Therefore, when conducting wire harness insertion and extraction force testing, it is necessary to evaluate according to relevant standards and specifications, and ensure that the wire harness's insertion and extraction performance meets specific requirements.
