2.4 -end bullets failure

The most direct effect of the terminal shoch is to provide reliable positive pressure F for effective contact with the plug terminal and the socket terminal to meet the reliability of current and signal transmission (Figure 10).

The faulty situation of the terminal bullets is generally caused by the following reasons: ① The bullets caused by the gap in the end of the terminal during the production process cannot be contacted with the plug terminal, and then it cannot provide reliable positive pressure F for the plug terminal. 11); ② During the electrical inspection process of the terminal installation of the terminal, the shot of the shot caused by excessive squeezing the shot inspection is not rebounded due to the probe of the electrical inspection (Figure 12); The squeezing side bullets cause the terminal shells to not rebound; ④ The root of the end bullets is bent and the arc R is too small, and the stress concentration generates. During the deformation process, plastic deformation was generated in the bending arc root (Figure 13).

Therefore, the solution to the failure of the end of the end bullet requires the strict production process to strictly control the bulk gaps and arc root size of the end of the terminal, as well as regular inspection of electrical inspection tools and regulatory rework and repairs, which can minimize the occurrence of shift failure.

In summary, the form of the connector will include breaks, ending abdication problems, sealing problems, and end -of -end bullets failure. Therefore, when designing and selection, it is necessary to determine the connection performance detection items according to the environment of the connector. At the same time, the connector operation specifications must be strictly executed to avoid defects caused by improper operation.
