Abstract
A detonator for a perforating gun. The detonator is used to ignite a detonator cord in a charge tube for a perforating gun assembly. The detonator includes a cartridge. The cartridge comprises a tubular body having a first end and a second end. Preferably, the tubular body is fabricated from a metallic material. The detonator also comprises a post proximate the first end of the tubular body. The post is configured to be in electrical communication with a first leg wire connected to an addressable switch. Alternatively, the post is in contact with the end of a detonation pin or with a pair of hot terminals. The detonator also has a fuse head within the bore of the tubular body, and a fuse wire. The fuse head is in contact with the explosive charge material. The detonator is releasably snapped into a compartment located within the charge tube.
