(54) Detonator for a non-electric detonation system for blasting charges


(57) The present invention relates to a detonator for nonelec- tric detonation systems for blasting charges intended to be initiated by a detonating fuze (14) which passes through a passage (13) provided for this purpose in the body (9) of the detonator (5). A major characterising feature of the detonator (5) according to the present invention is that a conventional percussion cap (10) which is immediately initiated by the detonating fuze (10) is utilised for initiating the detonator.
The invention also relates to a booster charge (1) intended for the detonator and provided with a reinforced central channel (16) for the detonating fuze (14).
