Abstract
A block molded from a polymeric material has a through passageway to contain a percussive shock wave. Angularly related channels communicate with the containment passageway for receiving arcuate segments of detonation cord. Alignment of a plurality of blocks provides a convenient packaging setup for the cord. A percussive signal traveling along the cord can be short-circuited in the packaging setup. A diode version of the block can react to the signal in a given direction of travel.
