Definitions

  • the present invention relates to pyrotechnic products for fireworks and relates more particularly to the ignition of pyrotechnic products.
  • a pyrotechnic firework product generally consists of a tubular casing made of cardboard or the like which contains a dose of ignition powder linked by a delay to a firework composition.
  • the ignition powder is connected to a wick, the ignition of which is ensured using a lighter.
  • Electric ignition means are also used in which case the end of the wick opposite the dose of ignition powder is placed in contact with an igniter or match, constituted by a conductive filament coated with a flammable composition and connected by two electrical conductors to an energy source such as a battery.
  • connection between the wick and the igniter is generally protected by a plastic or cardboard sleeve surrounding the igniter, in which it is engaged.
  • connection between the wick and the igniter is devoid of weather protection.
  • the invention aims to remedy the above drawbacks of conventional connection means by creating a connection device between an igniter and a fuse for igniting a pyrotechnic product, which, while being simple in construction, is quick to install. and has increased operational safety.
  • a connecting device between a firing wick of a pyrotechnic product and an electric igniter characterized in that it comprises a nozzle forming a socket fixed to one end of the wick and a sleeve surrounding the igniter, and forming plug, engaged in said tip.
  • the pyrotechnic product which represents in FIG. 1 is a firework rocket 1 provided with a firing wick 2 connected to an igniter connected to a source of electric energy such as a battery by an electric wire 3 to two conductors via re of a connecting device 4 according to the invention.
  • connection device between the wick and the igniter shown in Fig.2 essentially comprises a nozzle 5 forming a socket provided with a tubular connection 6 made of material engaged between the wick 7 itself and the sheath 8 of plastic material this one.
  • the connector 6 advantageously has external projections 9 intended to ensure its axial retention with respect to the sheath 8 and internal projections 10 for axial maintenance of the wick 7.
  • the end piece 5 has a flange 11 facing inwards intended to ensure the holding in position of a sleeve 12 forming a plug and containing an igniter 13 whose resistive filament 14 surrounded by a flammable material 15 is connected to two electrical conductors 16 intended to be connected to an energy source such as a battery, not shown.
  • the tip 5 and the sleeve 12 forming a plug are advantageously made of plastic.
  • the endpiece 5 also has axial slots 17 intended to facilitate the insertion of the sleeve 12 forming a plug into the cavity of the socket 5 by spacing its side walls delimited by the slots, the inner rim 11 of the socket closing on the rear end of the sleeve 12 to immobilize it in translation.
  • the slots 17 also allow the withdrawal of the sleeve 12 and consequently of the igniter 13 by spacing the lips formed by the rim 11.
  • connection device which has just been described is supplemented by a plastic cap 18 which covers the end piece 5 and clamps the conductors 16.
  • This cap provides additional security for the connection between the end piece 5 and the sleeve 12 and improves the tightness of the assembly to bad weather.
  • Fig.3 there is partially shown a variant of the connecting device according to the invention in which the end piece 5 a is provided with internal axial grooves 19 extended by grooves 20 extending approximately perpendicularly to the grooves 19 and with which cooperate diametrically opposite lugs 21 provided on the outer surface of the sleeve 12a forming a plug.
  • the pins 21 are engaged in the axial grooves 19 and when they reach the bottom of these grooves, a rotation of the sleeve 12a ensures their engagement in the grooves 20 and the immobilization of the sleeve 12a relative to the nozzle 5a.
  • a bayonet device is known as a bayonet device.
  • FIG.4 there is shown a connecting device according to the invention incorporated in a pyrotechnic product.
  • the pyrotechnic product comprises an envelope 25 containing a mass of firing powder 26 and a wick 27 provided with a nozzle 28 forming a socket, housed in an axial orifice 29 of an end wall of the envelope 25.
  • a sleeve 30 forming a plug and protecting an igniter 31 is engaged in the socket 28.
  • the igniter 31 is connected to two electrical conductors which are intended to be connected to a source of electrical energy not shown tee.
  • FIG.4 shows that it is possible to integrate the connecting device according to the invention directly and therefore without intermediate cord to a pyrotechnic part.
