Electric ignition device of flameless explosives

Abstract

The invention discloses an electric ignition device of flameless explosives. The electric ignition device comprises a shell 2 and an electrode ignition device arranged in the shell 2, wherein the electrode ignition device comprises an insulated electrode fixing element 3, two electrode pin wires 1 arranged on the electrode fixing element 3 and an exploding wire 4 easy to be gasified under an electrified state; the electrode fixing element 3 is arranged in the shell 2; the electrode ignition device and igniting explosive 5 are separated and a closed cavity 6 is arranged between the electrode ignition device and the ignition explosive 5. The electric ignition device disclosed by the invention has the beneficial effects that the ignition explosive and an ignition bridge wire are separated structurally, the ignition explosive can be placed in an initial exploding element, the ignition bridge wire can be placed at the output end of a fuze electronic-control and ignition module, and the initial exploding element and the fuze electronic-control and ignition module belong to different structure modules from the aspects of technical principle and process, so that the problem that the bridgewire is buried into detonating explosives to cause poor reliability and performance stability in the production process of the bridge-wire type electric exploding element can be effectively solved, the benefit for specialized production management, safety management and quality control is achieved, and the cost is lower.

Description

technical field [0001] The invention belongs to the technical field of pyrotechnics, and in particular relates to an electric ignition device for non-fired explosives. Background technique [0002] At present, the working principle of all bridge wire type EEDs is: the current passes through a thin bridge wire between two electrodes, and the electrical energy is converted into heat energy on the bridge wire according to the Joule-Lenz law, and the bridge wire heats up, and the heat is transferred to Agents that come into contact with bridgewires. The temperature of the agent rises, causing it to undergo a chemical reaction, and the heat released by the chemical reaction of the explosive makes the agent continue to heat up, accelerating the reaction until it ignites automatically. However, the glowing bridge wire pyrotechnic product is a combination of electronic components and pyrotechnic products, electronic technology and pyrotechnic product technology, and its production ...
