Abstract
Description
Subject of the invention report
[0001] The subject of this report is an electronic ignition device for pyrotechnic compositions to ignite any pyrotechnic system without having to splice wires when assembling the triggering components.Background to the invention
[0002] There are pyrotechnic compositions on the market that are usually triggered by electronic ignition systems that splice wires and connections through remote firing racks with the same terminal-free wiring system. These assemblies are carried out in situ wherever the pyrotechnics are to be set off, with tight deadlines that can be affected by weather conditions, often leading to miscalculations entailing consequences of a greater or lesser extent, but always carrying a certain risk for the user, not to mention those in attendance.
[0003] In turn, there are other known adverse effects that can lead to accidents in current remote firing systems, such as the so-called "coil effect", caused by long wire lengths, as they tend to become coiled and can produce a magnetic field that builds up in the centre of the wire leading to malfunctions or failures therein, such as accidental firing.
[0004] The solution herein proposed is a system comprising the two polarities brought together and isolated in a housing system, thereby making the assembly of the pyrotechnic compositions much more straightforward and quicker, while preventing possible accidental disconnections and most of the safety issues inherent in current firing systems.Description of the invention
[0005] The technical problem that this invention solves is that it reduces the complexity and risk involved in handling, transporting and assembling pyrotechnic compositions. Therefore, the electronic ignition device for pyrotechnic compositions that is the subject of this utility model comprises a metallic housing unit with two wires coming out of it and connected with a pyrogen at the upper end thereof, as well as an insulating element and a high-power magnet at the base thereof.
[0006] Due to its design, the metallic housing unit can keep all the pyrotechnic compositions where they should be by simply pressing in place the compositions used therein, without the need for threads or welding, thereby preventing uncoupling or breakage due to fatigue.
[0007] In turn, this system has a very short wire length, thereby preventing possible damage thereto, such as breakage due to fatigue or trampling, or the so-called "coil effect" because it is not long enough to produce its own electromagnetic field or to absorb a surrounding current.
[0008] With regard to triggering, the electronic ignition device is coupled to the pyrotechnic composition to be triggered by means of a receiver orifice, thereby leaving the pyrotechnic composition to be detonated ready to be triggered, with no need for any further handling other than being placed on a platform that gives the electrical firing signal.
[0009] With regard to the magnetic field, the central polarity of the composition is connected to a central terminal created by a powerful magnet that produces a stable and permanent magnetic field, that prevents other electromagnetic fields from penetrating the system, thereby eliminating the risk of a stray current accidentally triggering the system while making the electronic ignition device easier to transport due to having the pyrotechnic compositions already built in.
[0010] Lastly, the electronic ignition device can be combined with other pyrotechnic composition safety systems, such as, for example, tip-over detection systems commonly used in pyrotechnic projection systems, that block the pyrotechnic compositions from being triggered in the event of a tip-over in a direction undesired by the user.Brief description of the figures
