Abstract
A detonator (10) has a constant-diameter shell (12) which has a significantly higher shell length-to-diameter (outside diameter) ratio than prior art detonators. The shell (12) is configured to hold an explosive output charge (18) which is cylindrical in configuration and has a charge L:D ratio which is greater than that of prior art constant diameter detonators. As a result, a significant portion of the output signal of the detonator is directed laterally and it is feasible to transfer signals to a plurality of receptor lines disposed along that portion of the length of the detonator which is co-extensive with the length of the explosive output charge (18). A connector block (26) is configured to hold at least one array of receptor lines in side-by-side arrangement along the side of the detonator (10), and transversely to the longitudinal axis of the detonator (10).
