Pyrotechnic detonator using coaxial connections

A pyrotechnic detonator with coaxial connections comprising

• electrical projected-layer control means including a barrel, a first cylindrical element forming an anvil, which has a bottom ana an opposite surface with a circular edge and an assembly including a fusible bridge with two ends and a thin layer of a material disposed on said bridge, said assembly being located between said anvil and said barrel;
• electrical supply means for said control means, including at least one conducting surface situated on the bottom of the anvil and hermetic electrical crossing means for connecting said conducting surface to one end of said fusible bridge through said anvil;
• pyrotechnic means when initiated by said electrical projected-layer control means;
• a second non-conducting cylindrical element formed as a hollow plug having a cylindrical body, and having a first end and a second end, said first end being pressed against said anvil and said second end having a guide shoulder;
• a cylindrical flexible contact part being fitted around said plug between said shoulder and the circular edge of the anvil;
• assembling means for hermetically sealing said plug to said anvil;
• and
• hermetic closing means for hermetically sealing said detonator, said closing means being fixed at said second end of said plug and holding the pyrotechnic means inside said plug against said barrel.
