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), the outlet conductors of length greater than the depth of the cavity forming an ignitor line (9) short circuited outside the mass of resin inside the cavity (11), which cavity is provided with a removable end cap (12).
