The nitrogen micro-actuator in the security device is connected with a silicon / organic glass base plate main body through a fixed-connecting bridge, an integral structure is formed, the assembling process is simplified, the security device can conduct arming by not depending on environmental force, and the reliability of the security device is improved; the security device adopts a gas producing explosive material based on a nitrogen generating agent, the driving pressure can be ensured, large displacement is achieved, the gas producing temperature can further be controlled, and accidental detonation is prevented; and in addition, the explosion initiating sequence based on the security device is further provided with the structures of a flyer and the like, and the output capability of an output explosive is improved, so that detonating of an insensitive explosive is facilitated.

Description

technical field [0001] The invention belongs to the field of MEMS pyrotechnics, in particular to a solid-state micro-security device based on a solid nitrogen micro-driver and its detonation sequence. Background technique [0002] Since the 1990s, European and American countries have conducted a lot of research on MEMS technology in fuze security systems, and have designed or developed various types of MEMS security mechanisms, including spring lock pin type, pneumatic slider type, electromagnetic brake formula and so on. However, MEMS technology still faces many problems in fuze safety mechanisms, such as micro-scale effects, inability to achieve large displacement and high overload resistance. [0003] The detonation sequence is generally an orderly arrangement of a series of pyrotechnics with excitation sensitivities from high to low and output energy from small to large, so as to achieve a controlled amplification of the smaller input energy to an appropriate energy, th...
