A detonator assembly is provide which increases versatility, reliability and safety by initiating any amount of signal transmission lines up to about 8 without emitting excessive noise or shrapnel which can cause cut off or safety hazards. The detonator assembly comprises a low strength detonator with a single charge of preferably lead azide. A high confinement connection block houses the low strength detonator and comprises a retention block in which the low strength detonator is inserted and a confining wall which surrounds the closed end of the low strength detonator. One to about eight signal transmission lines can be inserted through a gap in the confining wall and operatively confined adjacent the closed end of the low strength detonator.
