Device for interrupting a detonating cord and safe packaging method for such a cord

摘要

A block (10) molded from a polymeric material has a through passageway to contain a percussive shock wave. Angularly related channels (16) communicate with the containment passageway for receiving arcuate segments of detonation cord (12). 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. IMAGE
