[0027] combine figure 2 , a kind of fuze small-sized energy-gathering output flame detonator adopting a single charge according to the present invention comprises a shell 1, a single charge 2, a drug-type cover 3, and an additional silk pad 4, the shell 1 is cylindrical, One end is closed as the input end, and the other end is open as the output end. The center of the input end of the tube shell 1 is provided with a fire transmission hole, and the inner side of the input end is put into a silk pad 4 before pressing the medicine to cover the medicine at the input end of a single charge. Surface; all of the single charge 2 and the drug-shaped cover 3 are sequentially loaded into the tube shell 1, the drug-shaped cover 3 opens toward the output end and is pressed together with the single charge 2, and the single charge 2 is formed under the constraints of the drug-shaped cover 3 The energy-gathering recess is covered by the drug-shaped cover 3; the output end of the tube shell 1...

Embodiment 3

[0031] combine image 3 , a kind of fuze small-sized energy-concentrated output flame detonator adopting a single charge of the present invention includes a tube shell 1, a single charge 2, a drug-shaped cover 3 and a silk pad 4. Wherein the drug-shaped cover 3 adopts a conical energy-gathering drug-shaped cover structure, and the diameter of the mouth of the conical energy-gathering socket of the drug-shaped cover is half of the charge diameter. All the other structures and charges are the same as in Example 2. The cone angle of the drug-shaped mask is 60°, the material is pure aluminum, and the wall thickness is 0.2 mm. The detonator has a diameter of 3.85 mm and a height of 3.2 mm.

Abstract

The invention discloses a small-sized fuze shaped charge output detonator adopting single charge. The small-sized fuze shaped charge output detonator comprises a detonator shell, the single charge and a shaped charge cover, the single charge is a coprecipitation initiating explosive with lead azide as a main component, and the lead azide and tetraazene coprecipitation initiating explosive with high needling sensitivity and the lead azide and trinitroresorcinol lead coprecipitation initiating explosive with high flame sensitivity are used for the needling energy-gathered output detonator and the flame energy-gathered output detonator respectively. And meanwhile, power output charging is also achieved. The explosive loading structure of the detonator is simplified, the height size of the detonator is reduced, the explosive loading amount of the detonator is reduced, so that the explosive-proof safety of the fuze is facilitated, axial long-distance and large-power accurate output is realized by an energy gathering effect, and the explosive loading device is particularly suitable for the detonator with the diameter and the height being less than 4 mm and is used for detonating insensitive low-vulnerability explosive-conducting and booster explosive in an insensitive ammunition fuze.

Description

technical field [0001] The invention belongs to the technical field of pyrotechnics, and in particular relates to a fuze small-sized energy-gathering output detonator which adopts a single charge, helps to ensure the safety of explosion-proof and detonates low-fragility guide and booster charges. Background technique [0002] In order to increase the axial detonation ability of the engineering detonator, some products add an energy-concentrating nest structure at the output part of the bottom. However, since the power of the engineering detonator itself is relatively large, whether the adoption of the energy gathering nest structure has a significant effect on its power has been controversial in the field of pyrotechnics technology. Therefore, some of the engineering detonators on the market have an energy-concentrating nest structure, while others do not. But there is no obvious difference between the two in application. [0003] Fuze detonators are different from enginee...
