C 'file invention relates to a pyrotechnic «

component with a housing) at the head end a primer and iron metallic at the bottom edge Cover is attached, whereby in the housing between the primer and the cover at least a delay charge is arranged »

Mn such a delay component is described in DE-GM 74 23 532. Sa's primer is housed there in its own housing, which in turn is fixed to the housing of the delay component.This is done by flanging a collar of the housing of the delay component * Sa's primer first on its housing and then on the housing of the

sometimes it is time-consuming to attach

Task «the Brfiaduag is to be a

tell of the type mentioned voizusehlagea, that

encapsulated in a simple manner airtight and watertight is·

According to the invention, the above task is »Ögerungsbauteil of the type mentioned thereby solved that the primer was sunk into the Qehäuee is and the GeMlUBe overlaps the primer on the hand and that the joint between the edge and the Housing is sealed

As a result, the primer is held in a sealed manner in the housing. At the same time, it forms the closure at the head end of the delay component. That Housing is closed airtight and watertight so that its interior is hardly exposed to environmental influences is · The pyrotechnic delay component can therefore be stored for years · The described arrangement of the primer on the delay component provides high functional reliability both at high SQ and at low temperatures, because the primer is arranged within the housing itself.

Such a delay device can be seen as Explosive detonators, for example to ignite Thermit rods, teardrops & stoppers or mist pots, la Verb4nd% mg al *

ee for the ignition of SpreegfeSrpem, or hand grenades are used

Advantageous embodiments of the invention can be seen from the sub-claims and the following description of exemplary embodiments. Point in the drawing

Fig. 1 a deceleration component in longitudinal section}

2 shows a further embodiment of a delay component in longitudinal section

and

Flg. 3, a delay component neeh FIG. 1 is used

with an explosive detonator.

A tubular case 1 of a delay member is made of Measurement made, It has an external thread 2. In the housing 1

^ are one after the other a booster charge 3 and five delayed 4 charges pressed in. In the area of the bottom end, the housing 1 a collar 5 on which the booster charge 3 stands up » On the other hand, there is a die ring 6, e.g. made of Teflon, on the collar 5, to which it.?) a metallic cover 7 connects.

This consists, for example, of a lead-tin = foil »This cover is by a fire jet of the delay charge durehsehlagbaf.

On the cover 7, opposite the sealing ring 6, there is a flanged auxiliary ring S made of brass. A lower edge 9 of the housing 1 is flanged around its outer edge. This means that the bathing end of the housing 1 inf§ä $ e of the ZHäammewteöetens of the Abiteeteunf 1 is completely sealed and watertight.

The primer cap 12 is on the edge 13 of the housing 1 overlapped «This can be achieved in that the housing 1 is caulked in a ring on its end face is «you joint between the sand 13 and the Verstem · * mung 14 is sealed with a lacquer layer t5 «

In the embodiment according to FIG. 2, the parts corresponding to the described FIG. 1 are provided with the

and 19 between the cover 7 and the auxiliary ring 8 clamp a sealing washer, not shown in detail.

In the case of the explosive scale according to FIG. 3, this is the case Housing 1 screwed into a handle part 2O. Zn ■,

This a spring-loaded hammer 21 is mounted. This is held in the securing position shown by balls 22 on a pulling part 23. The pulling part 23 is connected via a band Zk to a head 25 screwed onto the handle part 20.

On the handle part 20 is the head 25 opposite Intermediate part 26 screwed, which the housing 1 encloses. In the securing position shown in Figure 3 sits on the intermediate part 26 a Protective cap 27

If after removing the protective cap 27 the explosive j

central detonator screwed onto an explosive and '

the head 25 is unscrewed and pulled off, then,

the tape 2k pulls the pulling part 23 out of the grip |

part 20. The punch J is over the balls 22 piece 21 taken along, whereby the spring tensions. If the balls 22 come out of the handle part 20, then the striking piece 21 is released and acts on the primer 12. This ignites the delay charges k _f so that after a certain time, both for example k to 6 β the booster charge 3 ignited
