Problems solved by technology

[0003]With the development of modern warfare, fuzes used in smart ammunition are required to have the functions of high safety, anti-static, anti-radio frequency, reliable ignition, etc., and are currently used in missiles The high safety of the used shock-blade detonator can meet the requirements, but the shock-blade detonator has a large volume and high ignition energy, which is difficult to meet the miniaturization requirements of smart ammunition
The smart fuze is composed of guidance system, detection system, safety system and self-destruction system, etc., the functional modules are increased, the actual volume is limited, and the power consumption increases

Embodiment Construction

[0015] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below.

[0016] The present invention proposes a micro-shock plate detonator with low ignition energy, which is mainly composed of a shell 1, a charge 2, a transducer element 3, and a wire breaker 4. The transducer element includes a glass-sealed electrode plug 9, a bridge foil 8, Flyer 7, acceleration chamber 6; the acceleration chamber is provided with a central hole;

[0017] Press-fit the charge (HNS) directly into the casing, the pressure of the charge is 120-140MPa, and the transducer element accelerates the chamber facing the charge and loads it into the casing, the acceleration chamber is in contact with the powder surface, and then installs the splitter 4 to Ensure the distance between the electrode pins of the transducer element, and then use the closing mold to close the mouth, ...

Abstract

The invention relates to a low-ignition-energy miniature slapper detonator which is mainly composed of a shell, a branching sheet, a transduction element and a charged explosive; a detonating circuit discharges the slapper detonator through a high-voltage capacitor; and when a strong current pulse passes through a bridge foil, a bridge area explodes to generate high-voltage plasma, a flying piece is punched to form a round piece with the diameter the same as the inner diameter of the center hole of an acceleration chamber, the flying piece accelerates along the acceleration chamber, the flying piece impacts an explosive column to reach the detonation threshold value of the explosive, and the charged explosive is reliably detonated. Compared with a traditional slapper detonator, the detonator is small in size and low in detonation energy, the energy conversion element is integrally designed, the structure is more compact, and the energy utilization rate of the detonator and the consistency of products can be improved.

Description

technical field [0001] The invention belongs to the technical field of pyrotechnics, and in particular relates to a low-ignition-energy micro-shock plate detonator. Background technique [0002] The pyrotechnic product is the energy conversion element of the ammunition detonation sequence, and is the initial energy source for the detonation of the ammunition. It realizes the functions of detonation, ignition and work, and has a significant impact on the safety, reliability and combat effectiveness of the ammunition. Since the SANDIA laboratory in the United States proposed the research on the shock plate detonator in the 1970s, the initiation energy of the shock plate detonator has developed from the initial 3000V / 5000A to the current 1500V / 2500A, and continues to develop in the direction of low energy 800V / 1200A. MEMS shock The chip detonator is small in size, low in cost, has no sensitive primary explosives, and has high safety. It can realize functions such as near-explos...
