An electronic delayed-action explosive detonator comprising a tubular case, a capacitor chargeable by pulses from a blasting machine, an integrated circuit for processing pulses from the blasting machine to set a delay time, the integrated circuit controlling the elapse of the delay time after the delay time has been set, a primer to which current is supplied upon elapse of the delay time for enabling detonation, and detonator wires extending from the tubular case for enabling connection of the blasting machine to at least one of the capacitor and integrated circuit. A supporting plate arrangement for carrying the integrated circuit is disposed in series with the capacitor within the tubular case. The supporting plate has a first contact area with connecting pads for enabling attachment of leads of the capacitor, and a second contact area with connecting pads for enabling attachment of the detonator wires which are within the tubular case and extend outwardly therefrom.
An electronic delayed-action explosive detonator comprising a tubular case, a capacitor chargeable by pulses from a blasting machine to store a charge sufficient to enable detonation, integrated circuit means separate from the capacitor for processing pulses from the blasting machine to control elapse of a delay time after the delay time has been set so as to enable detonation, primer means to which current is supplied upon elapse of the delay time for enabling detonation, detonator wires extending from the tubular case for enabling connection of the blasting machine to at least one of the capacitor and integrated circuit means, and supporting plate means separate from the capacitor for carrying the integrated circuit means, the supporting plate means being disposed in a series arrangement with the capacitor within the tubular case, the supporting plate means having a first contact area with connecting pad means for enabling attachment of leads of the capacitor, and a second contact area with connecting pad means for enabling attachment of the detonator wires within the tubular case and extending outwardly therefrom.
