Definitions

  • the invention relates to a pyrotechnic lighter for igniting propellant powder for caseless ammunition with an ignition element and a coil, in which the energy required for triggering is transmitted by electromagnetic (inductive) means.
  • the object of the invention is therefore to construct a production-technically uncomplicated and inexpensive, fully combustible, inductive lighter, which has no residues which damage the weapon function and, in principle, can be used universally in all common weapon calibres.
  • this object is achieved in that the ignition element and the coil are located on a common flat combustible or consumable carrier material.
  • the entire carrier material of the igniter consists of combustible or consumable substances, such as paper or nitrocellulose.
  • a spatial cylindrical coil is obtained, and the remaining ends of the conductor tracks form the connection surfaces (contact points) of the ignition bridge.
  • the electrical conductor tracks are expediently applied to the carrier material in a screen printing process and consist of silver or copper conductive paste.
  • the inductive igniter can be columnar or flat, consisting of a combustible or consumable electrical igniter and an induction coil with several turns and any external geometry, which is built or embedded on a flat single or multi-layer, combustible, insulating carrier material and the electrically conductive coil material can also be designed to be combustible or edible.
  • the entire inductive igniter is applied in one or more layers to a flexible combustible paper film or nitrocellulose film or another combustible carrier layer, the entire electrical conductor or conductor tracks being made of, for example, hardened silver or copper conductive paste or another metal compound or non-metallic combustible or edible conductor material, which is preferably applied by screen printing or another application method.
  • the inductive igniter is constructed in one piece and only functions as a result of reshaping and adding glow wire, conductive glue points and primer and is completely combustible or consumable. Further features of the invention emerge from the figures, which are described below.
  • Fig. 3 shows the finished lighter
  • Fig. 4 shows an alternative example of a flat lighter.
  • FIG. 1 shows a production example for a cylindrical receiving coil on flammable carrier material 5 and conductor tracks made of printed conductive paste with, for example, three turns in the non-plated-through state. Visible are the coil turns 1, the through-contact points 2, the connection point of the ignition glow wire 3 and the glow wire 4.
  • the ignition glow wire can be contacted with the connection surfaces 3, for example by gluing or bonding. Geometry, conductor cross-section and number of turns can be varied within a wide range.
  • Figure 2 shows the manufacturing process for reaching a solenoid by folding the coil ends and then contacting the coil ends 6 with the via points 7, advantageously with electrically conductive adhesive.
  • the stacked paper ends can be fixed with NC glue.
  • Figure 3 shows the igniter ready for installation.
  • the via points 7 are visible through whose center bore the coil ends 6 are contacted.
  • the substrate around the pads 3 can be due to its flexibility in one be fixed in a suitable position in the ignition chain and connected to a corresponding combustible body for receiving the igniter z. B. by gluing.
  • FIG. 4 shows a production example for a flat-lying receiving coil on flammable carrier material 1 and conductor tracks made of printed conductive paste with, for example, ten turns. Visible are the coil turns 2, the via points 3, the conductor tracks on the back 4 of the carrier material and the connection point of the ignition filament 5. Geometry, conductor cross section and number of turns can be varied within a wide range.
