高温电连接器绝缘件失效分析
Failure analysis of insulation part for high-temperature electrical connector
摘要
Abstract
Insulating materials tend to age,crack and even carbonize in high-temperature environments,resulting in a decline of insulation performance of high-temperature electrical connector and failure to meet the working requirements of equipment.Taking the J58 high-temperature electrical connector of a certain equipment as the research subject,the failure mechanism of its polyimide(PI)insulation part was analyzed and verified.At the same time,the variation of its insulation performance was investigated through high-temperature deterioration test.The results showed that after the PI insulation part was continuously operated at 450℃for 30 minutes,the insulation part showed carbonization trend,and its insulation resistance decreased significantly,but it was still greater than 5 GΩ,which could still meet the working requirements of a certain type of hypersonic missile.The research results provide a basis for the reliability design,selection and later maintenance decisions of high-temperature electrical connector,which is conducive to enhancing the reliability of equipment such as hypersonic missile.关键词
