Description

The invention relates to a display device for a detonator of a rifle grenade with one in one Recess of the detonator inserted squib, which is ignited by a firing pin, the Primer via gas channels with a plurality of openings arranged in the jacket of the primer in connection stands.

From BE-PS 5 65 993 a multiple fuze with several firing pins and detonators is known has, inter alia, a piece of metal that is radially outward through the combustion gases of a charge is pressed. This makes it possible to see whether the charge has been burned. However, one cannot see whether the detonator was actually hit by the firing pin and has deflated ineffectively.

In another known multiple fuze (reference "German Explosive Ordnance" United States Government Printing Office, Washington 1953, pages 556, 557) degassing channels are provided. If these degassing channels were to be closed from the outside with plugs, the resulting If gas pressure were to be ejected, it would only be possible to determine whether the charge actually burned down, however, not whether the detonator was fired by the firing pin.

The object of the invention is to provide a display device of the type described above, which makes it possible to determine in a simple manner whether the detonator is still armed.

This object is achieved in that the openings through the combustion gases Squib ejectable stoppers with a head protruding from the shell of the detonator body

ίο locked and arranged so that independent at least one plug is visible from the position of the rifle grenade

This makes it easy, depending on whether the stoppers are still in place or not, indicates whether the detonator is still armed

In the following an embodiment of the invention shown in the drawing will be explained; it shows the only figure shows a longitudinal section through a display device for a detonator of a rifle grenade.

The igniter 1 contains a in a manner known per se Primer 2, which is arranged in a recess 3 of a disc 4. The primer 5 has two diametrically opposed radial holes 6 and 7, which with the squib 2 containing Recess 3 are connected via channels, soft urnh urn ring groove 8 on the inside of the Shell of the ignition body 5, a milled recess 9 in the disc 4, a hole 10 behind the disc 4 and an axial channel 3a of the disk 4 can be formed. The radial holes 6 and 7 are provided with plugs 11 and 12, respectively a head 13 or 14 protruding beyond the jacket, so that they can be easily recognized from the outside. A firing pin 15 is located coaxially to the axial channel 3a and ignites the squib 2 when it strikes it.

If the squib 2 was not ignited, for example because the firing pin 15 was not triggered was, the plugs 11, 12 remain stuck in the radial holes 6, 7 and show as a result

clearly indicates that the detonator is still sharp. However, as soon as the squib 2 is ignited, the act the resulting gases via the channels 3a, 10,9,8 in the radial holes 6,7 stuck plugs 11,12 and throw them out so that it can be seen immediately that the detonator is no longer sharp and without danger can be eliminated.
