Oils innovation relates to a distance ignition device for a projectile that contains a head fuse with essential fuse parts.

In practice, projectile fuses are electronic or optronic distance function, as well as other essential Functions, in particular safety functions, are known. They are designed as integrated igniter units and are used, for example, as mine launchers, artillery projectiles or rocket projectiles at a high purchase price offered, due to the expensive electronic part. Much cheaper scale, e.g. 8. mechanical Head fuses, however, have no distance function. Especially for the area of application with explosives Between 2 and 12m there is therefore no economical alternative product for use with or without a spacer function.

The innovation, as it is characterized in the claims, solves the task of providing head detonators which have essential detonator functions with a spacing function in a simple and inexpensive manner.

The advantages achieved by the innovation are essential to see in it a surcharge and delay functions having head fuse in a distance fuse by attaching an adapter i.B. in the field can be converted, making et> v more economical Bet given 1st. By dl · expensive electronics only with 8 needs to be used, or when used * without a spacing function is saved. Furthermore, the adapter can be snug and light so that the ballistics of the projectile are practical is not changed.

In the following, the innovation is explained with the aid of a drawing which shows an exemplary embodiment:

In a projectile body 10 is a head fuse 11 with instantaneous (impact) and delay functions, convertible by the switching device 12, screwed in At the tip of the head detonator 11 there is an actuation button 13 which is used to move an ignition pin 14. Such head detonators are known and are therefore not explained in more detail here.

According to the innovation, placed on the head igniter 11 and attached to it is an adapter 20 which is provided as a distance ignition device. An adapter housing 21 contains, from top to bottom, a distance sensor 22 with an associated electronic circuit board 23. An electrolyte battery with contact pin 24, electrode stack 25 and electrolyte housing 26 as an electrical power source for supplying the distance ignition device with the required electrical energy, an electrical detonator, or here an electrical one Gas pressure capsule 27, and means for fastening the adapter housing 21 on the head fuse 11. These means consist in the use of three pins 28 evenly arranged on the circumference of the head fuse Ii, which form a bayonet lock with corresponding recesses 29 in the adapter housing 21, such that one annular support surface 30 of the adapter housing 21 lies snugly in the ogive of the head fuse U. A part 31, which contains the electrolyte housing 26 and the gas pressure capsule 27, is arranged axially displaceably in the adapter housing 21 through a groove-shaped recess 32 into which a pin 33 fastened in the adapter housing 21 protrudes. Another annular support surface 35 on part 31 supports the firm fit between adapter 20 and head fuse U.

Oils Mode of operation of the distance ignition device described 1st following:

If there is a need for a distance fuse, for example 1 m field, then an adapter 20 is placed on a head fuse 11 fastened to a projectile 10 by means of a bayonet lock. As a result of the launch shock when the projectile is fired, the electrode stack 25 breaks through a predetermined breaking point 36 attached to the cover of the electrolyte housing 26 and now forms, together with the stationary electrolyte housing 26, an electrolyte battery that can be activated. A sealing ring 34 ensures that the electrolyte liquid cannot flow off into the now empty space. After a certain activity tent, a voltage for the distance and ignition electronics is available at the battery poles. The electrical connection can be made, for example, via the contact pin and a contact ring attached to it in an insulated manner with corresponding contact points on the circuit board. A distance sensor of a known type, for example according to OE 2608066 C2, DE 2456162 C2 or DE 2949521 C2, now continuously measures the distance to a target and ignites the ignition means within a predetermined distance from the target, in this case the electric gas pressure capsule 27 or electrical contact tracks 41 and 42 as well as contact points 43 and 44. The gas pressure capsule 27 for its part simultaneously presses the actuation button 13 of the head detonator and thereby triggers the projectile detonation via the detonator pin 14.

Due to the displaceability of the part 31 fm adapter housing 21 the functions of handling, transport and a certain safety against falling for the adapter 20 as a single part guaranteed, the electrode housing 26 is held stationary only when it is placed on the head fuse will. But even in this position, a predetermined breaking point 36 must first be penetrated by the action of force.

the. to activate the battery, which also ensures load security.
