Abstract

The invention discloses an integrated electrode slapper exploder. The integrated electrode slapper exploder comprises an integrated electrode assembly and an acceleration bore. A reflector plate is arranged on the lower surface of the end of the integrated electrode assembly in a matched mode. The acceleration bore is arranged on the upper surface of the end of the integrated electrode assembly. The end of the integrated electrode assembly is tightly clamped between the acceleration bore and the reflector plate. A slapper layer and explosion foil are stacked up and down to be located between the acceleration bore and the end of the integrated electrode assembly. An acceleration bore hole is formed in the position, corresponding to the center of the explosion foil, of the acceleration bore. The integrated electrode assembly is formed by sequentially pressing a lower insulating layer, a lower electrode core layer, a middle insulating layer, an upper electrode core layer, an upper insulating layer, the explosion foil and the slapper layer. The lower electrode core layer is in circuit connection with one end of the explosion foil, and the upper electrode core layer is in circuit connection with the other end of the explosion foil. According to the integrated electrode slapper exploder, the upper electrode core layer, the explosion foil and the lower electrode core layer form a circuit loop. After the explosion foil is powered up, electrical explosion can generate plasma to impact the slapper layer, the slapper layer is made to fly out of the acceleration bore hole of the acceleration bore, and percussion charging is performed to achieve the detonation function of slappers.

Description

Technical field [0001] The present invention relates to the technical field of pyrotechnics, and in particular to an impulse piece detonator with integrated electrodes. Background technique [0002] Shock disc detonator is a kind of high-energy pyrotechnic device that is only sensitive to short pulses. It was first proposed by JRStroud of Lawrence Livermore Laboratory at the annual meeting of the Fuse Department of the Ammunition Technology Department of the American War Readiness Association. Its safety and excellent reliability have received extensive attention from research institutions and the military, which has allowed it to develop rapidly and be widely used in inline fuzes. Due to the needs of the battlefield environment, the fuze system has always been miniaturized and integrated as the development direction, especially with the development of MEMS technology, the integration of the fuze system is getting higher and higher, and the integration of the corresponding impact...
