Definitions

  • An impact head igniter of this type is known (see US-A-4 230 042) which has two igniter housings, the front of which is made of a light material, e.g. Plastic, and the other is steel.
  • This known detonator is therefore relatively heavy and therefore does not meet the requirement for a relatively light detonator.
  • a “switchable detonator” can be switched from instantaneous ignition to delay ignition.
  • an ignition pin which can be activated by the impact of the projectile in the target.
  • the momentary ignition takes place before the projectile has penetrated deep into the target.
  • a device is available for the delay ignition, which initiates the ignition only after the bullet has hit the target.
  • the delay firing only takes place when the projectile has penetrated deep into the target. If the projectile is to penetrate a concrete wall, there is a risk that the delay device, which is an “essential detonator part”, will be destroyed or the ignition will take place too early.
  • the object to be achieved with the present invention is to create a light detonator that is as deep as possible in a hard target, e.g. penetrate a concrete wall and ignite reliably, i.e. it should be prevented that e.g. the delay ignition is destroyed prematurely by deformation on impact in the target.
  • a light metal housing 11 is screwed into a projectile body 10.
  • a steel housing 12 and an igniter housing 13 are screwed into this light metal housing 11.
  • This detonator housing 13 contains an amplifier charge 14 and projects into an explosive charge 15, which is located inside the projectile body 10.
  • a first thread 16 connects the projectile body 10 and the light metal housing 11 and a second thread 17 connects the igniter housing 13 to the light metal housing 11.
  • the same thread 17 is also used to fasten the steel housing 12 in the light metal housing 11.
  • An actuation button 18 is arranged in the tip of the light metal housing 11 , which is used to move a firing pin 19. So that no moisture can penetrate into the igniter, the actuation button 18 is covered by an elastic cap 20.
  • a switching device 21 which prevents the ignition pin 19 from being displaced when the button 18 is actuated, is used to switch the igniter from instantaneous ignition to delay ignition.
  • the firing pin 19 is used to pierce a squib, not shown, which is located in a slide 22.
  • the slide 22 is slidably mounted in a carrier 23.
  • the carrier 23 is fastened in a manner not shown in the igniter housing 13 and has a bore 24 through which the ignition pin 19 can pierce the primer capsule as soon as the slide 22 has been moved from a safety position into an arming position.
  • the steel housing 12 protects both the pyrotechnic components and the delay device (25) from premature destruction in the event of an impact.
  • the switching device 21 is set to delay detonator, when the projectile hits the target, the actuating button 18 is also pressed in, but it does not push the firing pin 19 against the primer in the slide 22.
  • the projectile is then only after the by the delay device Serve hit at target. During this time, the projectile can penetrate deep into the target, e.g. a concrete wall.
  • the pyrotechnic components and the delay device (25) must not be deformed to such an extent that they become inoperable. These deformations are prevented by the steel housing 12 inserted into the light metal housing 11.
