Definitions

  • a known time delay detonator of this type contains a spherical rotor which is rotatably mounted in a cavity of the detonator housing.
  • the firing pin, this cavity and the booster charge are on the igniter axis.
  • the rotor contains a primer in a through bore of the rotor and a disk-shaped ring which projects into a groove in the rotor holds the rotor with the primer in a safety position. To release the rotor into its armored position, the disk-shaped ring must be pressed flat by the launch acceleration and expanded by the swirl.
  • a known securing device for swirl projectiles of this type according to the German design specification 25, 39, 750 contains a horseshoe-shaped securing element which can already be deformed by the swirl to such an extent that the rotor can be turned into its armored position. Such a security element does not meet the security requirements that are often placed on such security devices.
  • the object of the present invention is to provide a safety device which corresponds to the safety regulations, i.e. that the security element should only release the rotor when two independent forces, e.g. Accelerate launch and spin on the security element.
  • reliable transport security must be guaranteed.
  • the safety device according to the invention is characterized in that the annular disc (31) is divided into segments (34-39) by incisions (32, 33), the successive segments (34-39) being directed alternately upwards and downwards in a wave shape.
  • the base igniter has an essentially cylindrical housing that can be screwed into an unillustrated projectile body of a swirl projectile with an external thread 11.
  • a bearing body 12 is screwed into a bore 13 which has a shoulder 14 on which a guide sleeve 15 is supported.
  • a guide disk 16 sits on this guide sleeve 15 and is pressed by the bearing body 12 against the guide sleeve 15, so that the parts mentioned are fixed in the housing 10.
  • a hammer sleeve 17 is slidably guided with its lower part in the guide sleeve 15 and with its upper part in the guide disc 16.
  • An ignition pin 18 is attached to the upper part of the hammer sleeve 17.
  • In the bearing body 12 there is a spherical rotor 19 which contains a primer 20. The rotor 19 can be rotated from the safety position shown into the arming position by the swirl.
  • An amplifier charge 21 is also fastened to the bearing body 12 and protrudes into the explosive charge (not shown) of the projectile body.
  • a disassembly spring 22 is supported on the one hand on the bottom of the housing 10 and on the other hand on the hammer sleeve 17 and strives to push the hammer sleeve 17 against the primer 20 with the firing pin 18. This shift is prevented by a number of locking bodies 23 which are supported on the one hand on the guide disk 16 and on the other hand on a shoulder 24 of the hammer sleeve 17.
  • a bolt 25 is located inside the disassembly spring 22 and serves for it Guide.
  • the segment-shaped locking body 23 are held together by a centrifugal force band 26, which consists of a thin metal foil and is wound around the locking body 23.
  • spherical centrifugal bodies 27, which are located in radial bores 28 of the hammer sleeve 17 and are supported on the inside of the guide sleeve 15 under the action of the swirl on a conical surface 29.
  • An inertial body 30 is arranged behind the hammer sleeve 17 in the housing 10.
  • a securing spring 31 in the form of an annular disk below the rotor 19, by means of which the rotor 19 is secured against rotation into its armed position before the projectile is fired.
  • this disc 31 can be seen in FIGS. 2 and 3. 2 and 3, an annular disk 31 is divided into three segments 34, 35, 36, 37, 38, 39 by three inner incisions 32 and two outer incisions 33, the disk 31 being open at point 40. Viewed from this point 40, the segments 38 and 39 in FIG. 2 are directed upwards. The adjoining segments 36 and 37 are inclined downwards and finally the last two segments 34 and 35 are directed upwards again. Due to the incisions 32 and 33, the securing spring 31 is weakened such that the six segments mentioned can lie flat in one plane due to the launch acceleration and that the opened ring can expand due to the swirl.
  • the spherical rotor 19 has an annular groove 41 into which the annular securing spring 31 projects.
  • the Bearing body 12 has a groove 42 which is expanded in the lower region of the locking spring 31 so that the locking spring can expand in the radial direction as soon as it is pressed flat.
  • the inertial body 30 and the hammer sleeve 17 are accelerated forward.
  • the inertial body 30 thus drives the hammer sleeve 17, as a result of which the firing pin 18 fastened to the hammer sleeve 17 strikes the primer capsule 20 at the required speed.
  • the rotor 19 is primarily due to the six corners of the ring-shaped disk 31 designated with A or B 3 secured. With the outer corners A, the disk 31 is supported in the groove 42 of the bearing body 12 and with the inner corners B, the disk 31 is supported in the groove 41 of the rotor 19, thereby preventing the rotor 19 from rotating unintentionally.
