Bidirectional delay connectors for detonating fuse having a shell containing two detonating explosive charges, each end of the shell adjacent the detonating charges adapted to receive detonating fuse, heat-sensitive charges adjacent each detonating charge and in close proximity to exothermic charges in opposite ends of a metal relay capsule. A heat conductive metallic delay element is positioned between each heat-sensitive charge and said relay capsule containing exothermic charges. |
