Abstract:
An initiator tip for use with an initiation device for initiating an explosive material contained within a shock tube, the initiator tip comprising:an electrode assembly, the electrode assembly comprising concentric inner and outer electrodes, the inner electrode being disposed within the outer electrode and insulated from the outer electrode by an insulative material;first and second primary electrical contacts, each of said primary contacts having a first end and a second end, the first end of the first primary contact being conductively coupled to the outer electrode, the first end of the second primary contact being conductively coupled to the inner electrode, the second ends of the primary contacts being disposed for connection to an initiation device such that when an initiation device connected to the second ends of the primary contacts produces a differential voltage between the primary contacts, a percussion spark is generated at distal ends of the inner and outer electrodes, wherein the inner electrode is comprised of a material having a relatively high melting point.
