A basic detonator

The present invention discloses a primary detonator, whose structure includes a detonator shell, a tube groove, a third pressing charge layer, a second pressing charge layer, a first pressing charge layer, a paint layer, a through hole, a strengthening cap, a groove, and glass microspheres. The present invention has the following beneficial effects. By thickening the wall thickness of the detonator shell and increasing the pressing charge density of the primary charge, the initiation ability of the detonator is improved. At the same time, there is a groove on the detonator shell with glass microspheres adhered by paint. After the detonator explodes, the glass microspheres are shot into the explosive, forming bubbles that are stable and have a good physical sensitization effect, further improving the detonation ability of the detonator and making the detonator more conducive to detonating the explosive. By setting the contact surface between the second pressing charge layer and the third pressing charge layer as a conical groove, the contact area is increased and the reliability of initiation is improved. Compared with traditional detonators, the charge amounts of the priming explosive and the secondary explosive in the second pressing charge layer can be reduced, solving the problem that the shell disintegrates in advance due to excessive amounts of the priming explosive and the secondary charge, and the charge at the bottom of the detonator body cannot be normally initiated.
