常闭式触发开关失效分析及预防措施
Failure Analysis and Preventive Measures of Normally Closed Trigger Switch
摘要
Abstract
Trigger switch is the main part of trigger fuse. A trigger switch was assembled to the trigger fuse, which brought misacting before the normal bomb time in vibration test. The failure reason was analyzed by means of metallographic examination and energy spectrum analysis. The results showed that the main reasons were cladding material defects and unexpected existence. The reasonable thickness of gold layer and better process were promoted, and the comprehensive control measures for avoiding the trigger switch failure were given.关键词
