中文摘要：

针对引信 MEMS 接电开关 L 型梁闭锁机构存在的闭锁不稳定被弹开的问题，提出了改进后的微接电开关闭锁机构。该机构用 Z 型梁代替了 L 型闭锁梁，能够实现快速、稳定闭锁的功能。仿真验证表明：在选取了合适的倾斜角之后，该闭锁机构在3600 g 的后坐载荷下能完成预期的闭锁动作并能保证闭锁稳定性，在过载环境下也能确保结构不被破坏。

英文摘要：

Aiming at the problem in the bounced latching of the L-shaped latching beam for the MEMS latching structure,a new locking mechanism of the micro inertial switch with the Z-shaped latching beam was presented in this paper. The mechanism took the place of the L-shaped beam with the Z-shaped beam.The switch could stably and expeditiously finish latching.The finite element simulation of the new mechanism showed that,after selecting the appropriate tilt angle,the mechanism could complete the expected locking action in 3 600 g back-loading and ensured contact stably when locked,and even in the overload environment the mechanism would not be destroyed.
