电连接器失效模式及可靠性保障建议研究
|
摘要
电连接器主要担负着控制系统的电能传输和信号控制与传递,其质量的好坏直接关系到整个系统工程的成败。据统计,目前电子及电气装备的失效中有70%是由于电子元器件的失效引起的,而这些故障中的40%是由于电连接器的失效引起的。因此,对电连接器的失效模式进行了总结,并从器件设计和器件筛选两个角度提出了提高电连接器的可靠性的建议。
The electrical connector is mainly responsible for the power transmission and signal control and transmission of the control system,and its quality is directly related to the success or failure of the entire system engineering.According to statistics,at present 70% of the failures of electronic and electrical equipments are casued by the failure of electronic components,and 40%of these failures are caused by the failure of electrical connectors.Therefore,the main failure modes of the electrical connectors are summarized,and the suggestions for improving the reliability of the electrical connectors are proposed from the perspectives of device design and device screening.
