连接器漏水失效模式分析

Failure Modes Analysis for Leakage of Sealed Connector

汽车密封连接器的漏水会导致很严重的功能失效,但是其密封效果并非只是由连接器本身决定。从工艺、应用、设计几个角度探讨了可能会导致汽车线束密封连接器漏水的原因,如压接不良、选型错误、胶带包覆尺寸过长等。针对这些漏水原因给出了相应的预防措施,有效降低了失效发生的概率。

The leakage of automobile sealing connector can cause serious function failure, but the sealing effect isn’t determined by the connector itself.The reasons that might lead to leakage of automobile harness sealing connector were discussed from the aspects of technology, application and design, such as poor crimping, wrong selection, too long tape covering size, etc.The corresponding preventive measures were given to solve these leakage reasons, which effectively reduced the probability of failure.
