Definitions

the invention relates to a safety device according to the preamble of claim 1 for a spin lump igniter.
a safety device for a Vortex projectile igniter is for example in the EP 0 360 187 B1 described.
a retaining ring is formed with a keyway having radially inwardly oriented support tabs and between these recesses.
the support tabs and the recesses have approximately the same size footprint dimensions. This has an effect on the swirl-ie centrifugal force-related spreading behavior of the retaining ring.
This known safety device also has a spring device which is formed by a conical spiral compression spring.
the invention has for its object to provide a safety device of the type mentioned for a Vortex projectile igniter, especially for a medium-caliber weapon system, which is suitable for relatively high piecing and Zuclassbebuilditch.
the safety device has the advantage that the rotor for the detonator provided in the igniter body is released only when the launch acceleration and the spin-induced rotational acceleration is applied. This means that short-term pulses, such as those that occur in a drop test, are not detected as sufficient for ignition, so that the rotor remains in safety. In particular, extremely high feed and Ansetzbenchept be collected with the inventive securing device in an advantageous manner and not transmitted via the rotor to the internal structure. This leads advantageously to a high functional reliability.
FIG. 1 shows sections of a longitudinal section of an embodiment of the securing device 10 for a twisted roundabout igniter.
the safety device 10 has a detonator body 12 drawn in sections and also a bearing body 14, which is also drawn only in sections.
the igniter body 12 and the bearing body 14 are each formed with a hemispherical cavity, so that in the assembled state between the igniter body 12 and the bearing body 14, a spherical cavity 16 results.
a ball-like rotor 18 is rotatably mounted.
a detonator 20 is arranged in the spherical rotor 18.
the rotor locking ring 28 is provided in the equatorial connection region 42 between the igniter body 12 and the bearing body 14, which can be expanded in terms of rotation and centrifugal force.
the rotor securing ring 28 is arranged in a recess 44 which is formed on the end face 46 of the bearing body 14 which adjoins the igniter body 12.
the Recess 44 has the free space 34 for the rotationally and centrifugally spread rotor locking ring 28.
the igniter body 12 is formed with an annular, axially oriented receiving space 48 for the spring element 32 and the accelerating ring 30.
the acceleration ring 30 is axially movably guided along an axially oriented cylindrical guide surface 50 delimiting the receiving space 48 on the inside.
the receiving space 48 is formed with a stepped profile 52.
the stepped profile 52 results in an inside bearing portion 54 for the spring element 32 and an externally axially adjacent guide portion 56 for the acceleration ring 30.
the acceleration ring 30 has an L-shaped cross-sectional profile with a plant leg 58 for the spring element 32 and a holding leg 60th for the rotor locking ring 28.
