Abstract
A detonation assembly of a perforating unit of a downhole tool is positionable in a wellbore penetrating a subterranean formation, and includes a charge assembly. The detonation assembly includes a detonator housing positionable in the perforating unit and having an uphole and downhole ends; uphole and downhole connections positioned at the uphole and downhole ends, respectively, of the detonator housing; a detonator positioned in the detonation housing; and a trigger positioned in the detonator housing. The trigger includes a detonation switch and a detonator contact. The detonation switch is communicatively coupled, when in use, between a remote actuator and the detonator contact. The detonator contact is positionable in the downhole connection, and has spring-loaded arms extending through openings in the downhole connection to urge electrical contact with the charge assembly whereby an electrical connection is maintained between the detonator and the charge assembly.
