It is very common for the pins of wire harness connector terminals to retract, which affects the power and signal transmission functions of the connector. So, what factors are causing the wire harness connector terminals to retract?
1、 Factors causing unsatisfactory terminal retention of wire harness connectors:
Usually, the reason for the inadequate retention of terminals in the sheath is due to design and manufacturing issues with the wiring harness connector, as well as the materials used. The insertion retention force of standard specification wire harness connectors (connectors with a specification spacing less than 2.8) is greater than 40N, while the retention force of connectors with a specification spacing greater than 2.8 is greater than 60N.
2、 Interference factors caused by internal insertion of wire harness connector terminals:
When the male and female ends of the wire harness connector are in the insertion process, the automatic insertion of the male end into the non effective area of the female terminal leads to pin retraction and loss of connector function. This situation is usually caused by problems in the design and manufacturing process, one being structural design issues, and the other being issues with terminal insertion and extraction.
3、 Production process factors of wire harness connectors:
The production process factors of wire harness connectors include terminal crimping problems and terminal assembly problems. If the terminals are not crimped properly, excessive bending can cause the centerline of the joint area of the terminals to be non parallel to the crimping area. Moreover, excessive bending of the terminals can increase insertion force and affect assembly performance, and in severe cases, there may be a problem where the male terminal cannot be inserted into the effective area of the female terminal during the insertion process.
