Definitions
- the invention relates to an electrical ignition capsule according to the preamble of claim 1.
- an electrical igniter capsule from a housing that in addition to the electrical ignition device two Includes firing charges and an exhaust charge.
- This capsule has large fluctuations in performance with regard to ignition performance. Because of too fast Pressure rise and excessive gas pressure peak occurred in a large number of cartridge case travelers on. The primer has no cover, so for drop tests Block loosening occurred. Therefore, ignitions occurred during drop tests.
- the object of the invention is to propose an electrical igniter capsule Ignites propellant powder safely, has a uniform performance and that's for sure.
- the screen plate with sufficiently large gas openings and is essential the unbreakable but quickly tearing plastic film.
- the plastic film tears therefore defined in the hole cross-sections of the gas passages.
- the screen plate lies with a predetermined contact pressure on the plastic film and attaches the primer to the electrical Ignition device on. A gap formation in the area of the primer can therefore do not occur.
- the ignition wire bridge embedded in the ignition set according to claim 4 ensures the safe ignition of the primer. This is except for the pole face surrounded by the primer. This creates a large ignition surface.
- the plastic film is made of HDPE (High Density Polyethylene). This can also consist of another suitable plastic.
- An electrical ignition capsule 1 consists of a housing 2 on both sides has openings 4,5 closed by lacquer 3.
- An electrical ignition device 11 with pole bodies is located in a receiving bore 10 12,13 and insulating ring 14 located between them.
- One except in the middle horizontal ignition wire bridge 15 is with the pole bodies 12, 13 in a known manner soldered.
- An ignition charge 20 is pressed and encased on the electrical ignition device 11 the ignition wire bridge 15.
- the ignition charge 20 is made of a break-proof, but rapidly traveling plastic film 21 covered with high pressure polyethylene (HDPE).
- HDPE high pressure polyethylene
- a cup 25 is pressed into the receiving bore 10 and contains an ejection charge 26.
- the bowl 25 is formed on the bottom side as a sieve plate 28.
- the cross sections the gas flow openings 29 amount to 50% of the unspecified Cross section of the receiving bore 10.
- a flanged edge 32 fixes a ring 33 and a disk 34 Cup 25 is fixed and presses with a certain pre-tensioning force over the screen plate 28 the film 21 and the ignition charge 20 on the pole body 12, 13.
- the ignition capsule 1 has a relatively large discharge charge 26 and with the same length with the known igniter capsule. This will be mainly achieved by saving space by the ignition capsule according to the invention 1 has only a single ignition charge 20.
- the film 21 has the tasks of holding the primer 20 and for one to ensure even ignition of the primer 20.
- the ignition wire bridge 15 fires asymmetrically. Due to the braking, damaging effect of the film 21 the igniter 20 is ignited across its entire cross section. The The discharge charge 26 is therefore ignited through all gas flow openings 29 and not just part of it.
- the film 21 can also be made of plastic or metal, such as copper, aluminum or from a suitable composite material consist.
