Miniaturized priming chain

Abstract

A modular miniaturized priming chain has a detonator and a priming booster assembly. The priming booster assembly includes a first priming booster and a second priming booster which can be modularly combined together depending on the respective power requirement at an output of the priming chain, or only the first priming booster is combined with the detonator, which is a miniature detonator.

1 . A miniaturized priming chain, comprising:
 a detonator; and   a priming booster assembly having a first priming booster and a second priming booster;   wherein said first priming booster and said second priming booster are modularly combinable together depending on a respective power requirement at an output of the priming chain.   
   
   
       2 . The priming chain according to  claim 1 , wherein said detonator is a miniature detonator having a charge of a small mass and said detonator is configured for a directed generation of a power thereof emanating from a central initiation location towards a detonator base, and said detonator base has a concavely indented configuration for transformation into a flat disc flyer of high speed. 
   
   
       3 . The priming chain according to  claim 2 , wherein said charge comprises a primary charge and a secondary charge adjoining said primary charge, wherein said primary charge is disposed in a centering element of said miniature detonator and said secondary charge adjoins said concavely indented detonator base. 
   
   
       4 . The priming chain according to  claim 3 , which further comprises an electrical bridge element for initiating the primary charge. 
   
   
       5 . The priming chain according to  claim 4 , wherein said electrical bridge element is disposed on an electrically insulating bottom closure element of said miniature detonator, and wherein connecting elements contacted with said bridge element extend out of said bottom closure element. 
   
   
       6 . The priming chain according to  claim 5 , wherein said electrically insulating bottom closure element includes a peripheral sleeve. 
   
   
       7 . The priming chain according to  claim 3 , wherein said centering element is mounted to an extension sleeve. 
   
   
       8 . The priming chain according to  claim 7 , wherein said electrically insulating bottom closure element includes a peripheral sleeve, and a compensating sleeve disposed between said peripheral sleeve and said extension sleeve of said centering element. 
   
   
       9 . The priming chain according to  claim 2 , which further comprises a detonator peripheral casing, and wherein said concavely indented detonator base is formed integrally with a material said detonator peripheral casing. 
   
   
       10 . The priming chain according to  claim 9 , wherein said detonator peripheral casing, an extension sleeve of a centering element, a compensating sleeve and a peripheral sleeve of an electrically insulating bottom closure element are sealingly welded together at a connecting side remote from said concavely indented detonator base. 
   
   
       11 . The priming chain according to  claim 2 , wherein said miniature detonator forms a first stage of a miniature priming chain, and the miniature priming chain has second stage formed by an insensitive first booster. 
   
   
       12 . The priming chain according to  claim 11 , wherein said insensitive first booster has an entry diameter adapted to an exit diameter of said miniature detonator. 
   
   
       13 . The priming chain according to  claim 11 , which comprises a first booster housing formed with a receiving space opening in a funnel shape, and wherein said first booster has an insensitive explosive charge in said receiving space of said first booster housing. 
   
   
       14 . The priming chain according to  claim 13 , wherein said insensitive first booster is or can be combined with a second booster stage that also enlarges in a funnel shape. 
   
   
       15 . The priming chain according to  claim 14 , wherein said second booster stage is disposed in an associated second booster housing adjoining said first booster housing. 
   
   
       16 . The priming chain according to  claim 15 , wherein said second booster housing is formed with a concavely indented base configured to produce a flyer. 
   
   
       17 . The priming chain according to  claim 13 , wherein said first booster housing is formed with a concavely indented base configured to produce a flyer.
