Description

Technical Field

[0001] The invention relates to the technical field of high-voltage interlocking electric connectors, and more particularly to an online monitoring device for the effect of connector terminal assembly in place. Background Art

[0002] In today's automotive wiring harness industry, especially in the new energy vehicle wiring harness industry, quality accidents (such as ablation and power interruption) caused by connector terminal PIN withdrawal have occurred frequently, seriously affecting the safety of the entire vehicle; according to incomplete statistics, among the many factors causing connector terminal PIN withdrawal, the proportion of connector terminals not being properly assembled exceeds 50%;

[0003] In view of the above reasons, during the production stage of the automotive wiring harness production line, it is necessary to focus on the terminal assembly process and its subsequent installation monitoring process. Since the terminal assembly process involves many influencing factors (such as product structure and operator techniques, etc.), it is impossible to find commonalities and will not be discussed for the time being; this time we will focus on the production line terminal installation monitoring process.

[0004] According to industry research, in the current new energy vehicle wiring harness industry, in order to prevent the terminal from withdrawing from the PIN and outflowing, there are generally two ways to monitor the terminal installation. One is to apply force to pull back (usually manually), and the other is automatic spring probe ejection. Both of the above methods require force to the terminal, and both have their disadvantages. If the force is manually pulled back, it needs to be manually controlled, and the applied force value cannot guarantee its consistency. The automatic spring probe ejection detection can be automatically controlled by the program. Due to manual pullback, the terminal needs to be ejected from the plug-in surface, which has the risk of damaging the terminal. In addition, the two have a common problem, that is, once the terminal is deformed due to crimping or transportation, and then forcibly installed into the housing, due to the large fixing force of the terminal in the housing, even if the terminal is not assembled in place, the above two methods cannot effectively detect it, and thus cannot play a bad role in preventing outflow.

[0005] In summary, it can be seen that the existing terminal withdrawal and anti-outflow monitoring methods in the new energy vehicle wiring harness industry have the shortcomings of being unable to be automatically controlled, easy to damage the terminals, and unsatisfactory monitoring effects.
