Pyrotechnic trigger

The innovation relates to a pyrotechnic trigger for generating a thrust along a predeterminable path.

Such pyrotechnic triggers are used there, where a force element is needed that, after ignition, uses the energy generated in the primer as thrust delivers over a greater distance.

A miniature detonator of this type is described in DE-OS 18 16 027. This primer is characterized by that the ignition means, which consists of a primary charge with an ignition device, an intermediate charge and a main charge is arranged in a cylindrical metal sleeve which is closed off by two lids will. The bottom cover should also have a special shape.

A disadvantage is that the primer, despite its small size, has a complicated structure and also has no guide, within which a part of the primer perform a stroke of a certain length can.

The innovation is based on the task of developing a pyrotechnic trigger which is triggered when it is ignited generated a thrust along a path of several millimeters and at the same time in simple and for one inexpensive mass production can be produced in a suitable manner is.

This object is achieved according to the invention in that an electrically ignitable explosive contained in a can is arranged in a cup, which in turn is at least partially guided in a pipe section f. This is the explosive contained in the rifle arranged in the cup so that between the bottom j

the cup and the explosive pin expansion space f

remains free. "\

An embodiment of the innovation is shown in the drawing

tion and is described in more detail below. It shows I.

1 shows a pyrotechnic trigger. I.

The embodiment shown in the figure contains in |

a can 11 an electrically ignitable, qualified explosive 1, which is introduced into a cup 3, '

is. A mass-produced cup can be used as a cup

L, th deep-drawn part - such as here, for example, a Transi- {'

storkappe - find use that is the only modifi- | tion three on the circumference of the cup near the bottom 2 s three embossed beads 10 as a support for the sleeve;

of the explosive. This creates the expansion i sion space 4 between the explosive and the bottom of the beaker. Of the Cup itself is inserted into a pipe section 6

brought, which in the vicinity of the cup bottom 2 has a constriction 7 to support the cup. . The flanging S closes the trigger at the end opposite the bottom of the cup and also serves as a support for the sleeve 11,

Upon ignition of the explosive 1 occurs after burst the end face 5, the resulting gas in the expansion space 4 and drives the cup 3 against the resistance the pipe constriction 7 in the direction of the arrow 9

The advantages of the pyrotechnic trigger according to the innovation are particularly to be seen in the fact that it is inexpensive in a simple manner suitable for mass production can be produced, with no requirements being placed on precision and tightness of the connection points the must. It should also be emphasized that the trigger has a considerable length compared to its own length Able to generate thrust.

Claims (2)

1 16. Febr. I983 BTOl Mg / th 9335 Pyrotechnic trigger protection claims 1. Pyrotechnic trigger to generate a thrust along a predetermined path, characterized that an electrically ignitable explosive contained in a can (11) (I) is arranged in a cup (3), which in turn is at least partially guided in a pipe section (6). 2. Pyrotechnic release according to claim I _3, characterized in that the in the sleeve (II) contained explosive (1) in the cup (3) as above is arranged that between an end face (5) of the can containing the explosive (11) and a bottom (2) of the cup (3) an expansion space (4) remains free.
