ABSTRACT:
An initiator assembly (38) is factory-pre-assembled and comprises an initiation fixture (10) secured to a triggering device (40). The initiation fixture (10) comprises a unitary body, i.e., one without moving parts, and includes a bushing groove (18) to receive as an accessory an O-ring (64) to seal the device within the barrel (42) of the triggering device (40). A fuse/fixture sub-assembly (34) includes an initiation charge (30) disposed at the firing face (13a) and a signal-transmission fuse (22). The initiation fixture (110) may be a “universal” fixture having thereon optional external threads (36) and being otherwise dimensioned and configured to be received within either an internally threaded barrel (42) of a triggering device (40) or the barrel (42) of a triggering device which utilizes a fuse-holder cap (56). The initiator assembly (38) may include a spool (66) on which the signal-transmission tube (22) is wound.
