Title:

Application area and purpose:

Detonator fuse with delay device

The detonator detonator with delay device is intended to be airtight and watertight encapsulated delay device with longer burning time can be achieved, even with longer Storage time, regardless of the environmental influences, retains its full functionality. (10-15 years)

State of the art:

Detonators with delay devices are known and widely used in practice spread. For example, so-called fuses are used in the military and mining sectors equipped with a fuse, with a detonator being strangled at the end of the fuse and the ignition the fuse takes place over the fuse lighter. With these detonators, delay stages of, for example, 10 seconds to 1 hour can be achieved and can be achieved longer.

Furthermore, ignition means are known in the military sector, which by mechanical action e.g. by hitting or piercing with the help of a suitable ignition pin or with

7634810 05/28/77

Friction or draft fuses are ignited. These known detonators have delay devices up to 6 seconds, the delay device being a pyrotechnic There is a delay and this is always ignited by a primary ignition means.

The reaction time of the delay mixture results in a delayed time function, the either causes a blast as with detonators or as with other detonators may be the development of flame, heat or gas with a delay.

Criticism of the prior art: These known detonators with a delay device have the disadvantage that if the delay device consists of a powder set or a fuse, the same can only be stored for a limited time, e.g. 3 years and that after this time the desired Almost double the burning times as a result of chemical decomposition of the powder or the fuse or the desired delay times are definitely changed significantly. About it In addition, the function can be called into question in the case of extreme storage in the military sector.

Task:

The subject of the application is based on the task of a simple, safely functioning To create detonators with a delay device that can be stored for a long time with which any desired delay time is achieved and which is independent of Effects of temperature, humidity, etc.

Solution:

Achievable benefits:

a safe delay and a safe ignition of the detonator is guaranteed.

The object is essentially achieved in that the detonator has a delay device having, the delay by a slow burn-off of a pressed delay set arranged in a housing is effected, characterized in that single or multiple counter-acting in recesses of the housing Delay sets are arranged.

In the case of a simple burn-off, for example with a burning time of up to for 15 seconds, consist of metallic materials. With counter-acting delay sets, where delay times of up to 60 seconds are to be achieved, the housing can also be made of metallic, but also of ceramic Fabrics.

The advantages achieved with the subject of the application are in particular that a Detonator fuse with delay device comes about, with the longer delay times can be achieved and regardless of environmental influences, for example Can be stored for 10-15 years and is fully functional,

Another feature is that the detonator detonator has a delay device is easy and cheap to manufacture.

The delay sets are pressed into corresponding recesses in the housing, sealed watertight and screwed to the detonator.

Description of execution:

The execution of the subject of the application is shown on the drawing in longitudinal section and is described in more detail below

The detonator detonator with delay device preferably consists of the detonator cord 1.1, the wing nut 1 located on the detonator, the firing pin 1.2, the firing pin spring 1.3, the primer 1.4, the intermediate piece 2, the housing 3, the delay sets 3.1, the inlet pieces 4 and 5, the Seal 6, the ignition plates 4.2 and 5.2, the cover caps 4.1 and 5. 1, the seal 7, the detonator 8, the protective cap 9, the housing 10, the strangulation of the detonator the housing with delay set 10. 1. Pos. 8 shows how the detonator is moved in the intermediate piece 2.

The function of the detonator detonator with delay device is such that after Triggering the fuse, the primer 1.4 is ignited, the primer the Pushes through seal 6, pushes the pilot flame into opening 4.1 of the cover cap and pushes the delay set 3. 1 ignites, which burns down in the desired burning time, ignites the ignition plate 5.2, which then ignites the oppositely arranged delay rate

burns in the desired delay time and applies the second delay set the ignition plate 5.2 a third, fourth or fifth delay set for burning in the manner described.

After the delay set has burned off, the detonator 8, which is shown in FIG. 1 of the drawing is arranged under the delay set, or as shown in Figure 3 of the drawing, directly is choked on a delay tube, detonated.

Due to the simple design, a detonator comes with a delay device comes about, which was previously unknown, can be stored for a long time, regardless of environmental influences and water storage safe: works, all military requirements corresponds, can also be used for civil purposes and is easy and inexpensive to manufacture can be.
