Description
Technical field
The utility model relates to a kind of safety lead-in wire electric igniter, the no gunpowder that separates with payment to a porter that refers in particular to a kind of cost prepackage belt lacing low, safe and reliable, the easy to use electric igniter that goes between safely.
Background technology
In the market, be used for the automatically controlled electric igniter of setting off of firework and be the structure that contains gunpowder, namely at lead the resistance wire of one end short circuit is enclosed with a spot of gunpowder, and be one by bonding agent and anti-blushing agent with gunpowder and lead fixed.During use, electric current is directed to the resistance wire of short circuit between lead, and resistance wire generates heat rapidly, and then the gunpowder around being wrapped in of igniting, and powder burning produces flame and high temperature, and the fireworks leads around further will being fixed on is lighted.
Be to improve the rate of lighting of electric igniter, its gunpowder that uses often be the high gunpowder of susceptibility, thereby causes electric igniter itself comparatively responsive, friction or impact and all might trigger, with the preparation assembling process of fireworks in comparatively danger.Although therefore in the world with quick-fried lower UN0454, the 1.4S of extremely not being decided to be of the danger of this product, yet a lot of country is decided to be the control product with this electric igniter product, only allows to be sold to the professional user.
Electric igniter and lead are structure as a whole, and conductor length is about 3 meters usually, and material is a pair of copper core insulation lead of 24G, is the main body cost member of electric igniter.Electric igniter comprises that lead is disposable product, serious waste of resources.
The utility model content
Technical problem to be solved in the utility model provides a kind of directly by the heating resistance wire heating no gunpowder that separates with payment to a porter of safety lead-in wire and cost prepackage belt lacing low, safe and reliable, the easy to use electric igniter that goes between safely that ignites.
In order to solve the problems of the technologies described above, the no gunpowder that separates with payment to a porter of the prepackage belt lacing that the utility model the provides electric igniter that goes between safely, be folded with safety lead-in wire groove and circuit board slot under the plastics, folder is provided with a groove that patches that leads to the bottom that presss from both sides under the described plastics from described circuit board slot under described plastics, described circuit board is provided with two row's pins, the two ends of described heating resistance wire are electrically connected with two described row's pins respectively, described circuit board be fixed in the described circuit board slot and described heating resistance wire up, two described row's pins are positioned described patching in the groove down, position corresponding to described heating resistance wire on described circuit board is provided with a louvre, the safety lead-in wire groove that described louvre aligns and presss from both sides under the described plastics, folder is identical and provide closing force by elasticity part by folder under rotating shaft and the described plastics on the plastics.
Described heating resistance wire is the good spiral resistance wire of electric heating transfer capability.
Be covered with parent's weldering coat of metal at described heating resistance wire, reach reliable welding and protective effect.
Adopt the no gunpowder that separates with payment to a porter of the prepackage belt lacing of the technique scheme electric igniter that goes between safely, the louvre of on circuit board, opening that is positioned at the heating resistance wire bottom, the heat focussing force that heating resistance wire is produced goes between in safety, even the limited dry cell of power supply capacity also can go between safely by reliable ignition, prevent because of circuit board absorb heat after heating inhomogeneous, cause loss of ignition.
During use, lead is inserted the groove that patches of two last hole Du Pont plugs along the plastic clip bottom, effectively contact with two row's pins, the right other end of lead is linked in the ignition installation.Plastic clip is opened, with the lead-in wire groove position of fireworks safety cable guide in plastic clip, reliably contacted with heating resistance wire.When setting off, to being conducting on the heating resistance wire and persistent fever, electric current ignites safe lead-in wire by lead.
Compare with traditional electrical igniter head, the utility model does not contain the gunpowder composition, only by heating resistance wire heat generating spot combustion wire, and dependable performance; Storage, transportation and use all do not have any restriction, and general fireworks consumer can use, and is as safe as a house; Because payment to a porter separates with the igniting folder, but the payment to a porter that the cost accounting is the highest in igniter head part repeat function reduces use cost, economizes on resources.
In sum, the utility model is a kind of by the heating wire heating no gunpowder that separates with payment to a porter of safety lead-in wire and cost prepackage belt lacing low, safe and reliable, the easy to use electric igniter that goes between safely that ignites.
