ABSTRACT:
An explosive booster capable of being connected to donor and receiver detonating cords in the field via a cord-connector to propagate a detonation from the donor cord to the receiver cord, at least one of which cords is a low-energy detonating cord, has a granular explosive charge, e.g., PETN, between the walls and closed bottoms of inner and outer shells, the inner shell having an axial open cavity and the explosive charge being sealed off from the atmosphere. A length of detonating cord is inserted into the cavity of the booster in a manner such that an end-portion thereof is surrounded by the granular explosive in the spacing between the walls of the shells, the cord being held in the cavity by retention means located preferably in the cavity. Another length of detonating cord is positioned transversely outside and adjacent to the closed end of the outer shell, preferably in a transverse slot in a tube which holds the booster.
Initiation of the receiver cord by the booster explosive (the latter initiated by the donor cord) occurs even if the cord in the cavity fails to abut the bottom of the cavity.
