Electric detonator initiator

Abstract

The electric detonator initiator includes bridge filaments, pin wires, span determinator and sealing plug. The pin wires are integral with the base board for the bridge filaments, and each piece of pin wires is formed with one section of pin wire from the sealing plug to the bridge filament welding end and is variable flat cross section structure. The pin wires have their flat parts inside sealing plug, span determinator and welding end. Both the sealing plug and the span determinator are linked structure with several parts. The present invention has simple production process, and the electric detonator initiator has small dispersion of bridge filaments and high side rigidity.

Description

technical field [0001] The invention relates to an ignition device, in particular to an electric detonator ignition device. Background technique [0002] At present, the main structure of the electric detonator ignition device in the prior art includes a bridge wire, a foot wire, a bridge distance fixing device and a sealing plug, but the base boards of the foot wire and the bridge wire are independent of each other, and the whole production process of the product is as follows: figure 1 shown. Firstly, the galvanized thin steel strip 101 is subjected to fine blanking forming (made of silk substrate) and fixed bridge distance processing 102, then the end is bent 103, and threaded for compaction; then, bridge wires are welded 104, and excess bridge wires are cut off After 105, bridge wire resistance detection 107 is carried out; then, the propellant tip is sticky 108, and the tip is dried 109; finally, the bridge wire substrate 110 cut off at the end of the process and the s...

Problems solved by technology

There are following deficiencies in the product obtained by the above-mentioned process: (1) complex production process; (2) expensive production cost; (3) after the refined galvanized thin steel strip is punched, the punched position without galvanized layer is directly exposed, The effect of the chemical primary battery will accelerate the corrosion rate of the welded joints and reduce the stability of the resistance; (4) The material utilization rate of the refined galvanized thin steel strip is low; (5) The foot wire and the bridge wire substrate need to be welded separately; ( 6) It is very difficult to organize product production according to the serial production method, and there are many bottleneck factors in the production process when the product production is organized according to the parallel production method
