Abstract:
An electronic module for a detonator, the module comprising an electronic circuit (4, 5, 6) encapsulated in a mass of hardened resin (7) in which there terminates at least one inlet conductor (8) and from which there extend two outlet conductors forming a detonator ignitor line (9), the mass of resin (7) being received in a tubular housing (1) which extends beyond the mass of resin (7) adjacent to the ignitor line (9) to define a cavity (11), wherein the outlet conductors are longer than the depth of the cavity and form a short-circuited ignitor line (9) outside the mass of resin inside the cavity (11), which cavity is provided with a removable end cap (12).
