压接型连接器导线引起的低温信号传输故障分析

摘要

In this article, we introduce a fault modes of signal transmission interrupt under low temperature which caused by the wire and crimp parts do not match when using crimp connector.Guiding by the GJB5020-2001 standard, the failure mechanism is analyzed the failure mechanism from the aspects of electric resistance,resistance to pulling force,metallographic analysis.%文章针对一例压接型连接器因导线与压接件不匹配而引起的低温新号传输故障，以GJB5020-2001标准为指导，从电阻、耐拉力、金相分析等多个方面对失效机理进行了分析。
