Abstract

The invention relates to a bridgewire welding device for a novel digital electronic detonator, comprising two metal leg wires, a fuse head, a fixed block and a shell, wherein the two metal leg wires are positioned in the shell and extend out of the shell, one end of each metal leg wire is used for welding a bridgewire, the other end is used for connecting a firing circuit of the detonator, and both ends of the two metal leg wires are in sheet shapes; the fixed block is positioned in the shell and used for fixing the metal leg wires, and the shape of the fixed block is a cube with filleted corners; the inner wall of the shell is provided with a groove matched with the shaped of the fixed block, the shell includes two structures, one structure can fully encircle the fixed block, and the other structure does not encircle the fixed block and is connected with the metal leg wires used for welding the bridgewires. The invention enhances the welding reliability, realizes the automated welding operation and has good conductivity after welding and very low resistance coefficient or the resistance coefficient approximate to zero; the fixed block and the shell are formed into an integer with injection molding, thereby realizing the integrating; static-free polyvinyl chloride is adopted, thereby preventing the static; and in addition, the metal leg wires of the detonator are fixed in the fixed block, thereby preventing the short circuit between the metal leg wires.

Description

technical field [0001] The invention relates to the technical field of digital electronic detonators, in particular to a bridge wire welding device for digital electronic detonators. Background technique [0002] In recent years, digital electronic detonator technology has developed rapidly, and digital electronic detonators designed based on different technical factors have emerged in an endless stream. The applicant has also applied for patents on intrinsic safety and biometric identification (patent name: an intrinsically safe type Electronic detonator detonation system, application number: 200810227329.6 and patent name: a digital electronic detonator and detonation system based on biometric technology, application number: 200810227330.9), to meet a certain demand of the market. But at present, the bridge wire of the digital electronic detonator is all directly welded to two foot wires that are twisted together. After the power is turned on, the bridge wire is heated so ...
