Description
Technical field
The utility model relates to a kind of electron excitation dual platen conductive material electric discharge sparking gears.
Background technique
The igniting of traditional igniter wire powder head is that the igniter wire ignition device and powder head of electric cap and electric detonator are to light
The electric firing device of detonator.The performance of firing device directly affects the performance of blasting system.Ignition device more common at present
Including Bridgewire EED, membrane bridge priming system, Semiconductor Bridge Initiator, metal film bridge priming system, explosion membrane bridge fire
Work product etc..The fever of igniter wire formula electrical fire and the mode of action of ignition medicament are mainly conduction of heat mechanism.Igniter wire structure is simply
A kind of ignition and detonation mode generally used.Because high fever occurs for igniter wire when detonation, igniting head, then powder squib intracorporal are lighted
Quick-fried medicine.Make blasting cap initiation.
Conventional glow sparking gear is mainly insufficient:
1, produce dangerous: igniting head have inflammable, collision friction be easy on fire, fuse produce process to have it is very high
The precautionary measures, raw material have the characteristics that it is inflammable and explosive, either manual or automaticization medicine-feeding head assembly all there is very high wind
Danger.
2, precisely insufficient: all there is burn process time difference in igniter wire fuel factor and medicine head firing impulse, due to when
Between lag difference, be not able to satisfy the requirement of high-precision safety firing energy, igniter wire or powder head can not automatic chip mounting peaces
It is attached on the chip of electric detonator.
3, be used in series: igniting head firing time and conduction of being under fire extend time guarantee and are used in series, while also extending
Time reduces precision, as long as a hair igniter wire open circuit, whole network will stop working in series loop.
4, processing is complicated: igniter wire does not have welding and melts power, and suppressing contact causes complex process, is easy to aoxidize, and contact is not
Good, igniter wire silk thread is easy disconnected.
Sparking gear is the critical component of electric cap or electric detonator, its major parameter performance directly influences detonator production
Quality, and it is related to the development and application of product.There are more than 50 detonator production points in China at present, wherein more than ten enterprises adopt
With rigid ignition charge production technology, 20 many enterprises weld production technology using mechanical energy storage, separately have the enterprise of one third complete
It is manual welding production technology entirely.Electric cap overall quality level is poor, and Fire Reliability is low, so improving electrical fuze manufacture
Level is the key point for solving electric cap misfire and losing big gun.Electric cap and electric detonator at present on the market mainly uses igniter wire

The high problem of rate of miss-firing (rate of miss-firing > 3% or so), and be easily deformed during production and transport, fracture, product quality is difficult to protect
Barrier；Rigid igniter wire price is high, automatic welding higher cost, high to the sensitivity requirement of gunpowder.
Electronics sparking gear is mainly used in outdoor and underground mining, builds the road, builds water conservancy projects etc. in blasting engineerings, is used to
Quick-fried detonator, it may also be used for the control of fire-fighting fire extinguishing powder, fireworks lights, salvo, fireworks, video display explosion etc. the remote control point scene of a fire
It closes.The advantages of electronic ignition is compared to tradition igniting: safer, humanized, superpower controllability, instantaneity.Pass through electronics
The ignition installation person of setting off can not only do remote control control igniting to fireworks, but also can be right according to the needs of Theme activity
Time rhythm, whole imposing manner, aerial picture effect, the fireworks seted off carry out layout, so that activity is had more timing, the time controls more
Add accurate.Activity is pushed to a new high step by step, and energy effective guarantee sets off the personal safety of personnel.Electronics sparking gear substitution hair
Gunpowder head, powder head non-refractory is inflammable, and friction impact is easy on fire, dampness the problems such as misfiring, and manufacture was installed and used
There are risks in journey.
National annual detonator usage amount up to more than ten00000000 is sent out, and the sparking gear market demand is huge, for existing market situation,
As sparking gear, directly element is installed or is fabricated on circuit board with patch form, since sparking gear is solid-state components,
It is less likely to occur to damage in transport assembly, and high degree of automation is, it can be achieved that online 100% detection, the rate of miss-firing reaches ten thousand/
One, greatly improve production efficiency and product quality.The device can fill a hole in the market, and generate huge economic benefit.
Sparking gear is the critical component of electric cap or electric detonator, it directly influences product quality, its performance is straight
Connect the performance for affecting entire blasting system.Electron excitation dual platen conductive material electric discharge sparking gear described in the utility model,
Directly device is installed or is welded on circuit board using patch form and had not only improved effect but also safe and reliable.Change traditional igniter wire
With the technique of powder head.
