  • Publication number: 20240361112
    Abstract: A detonator includes a detonator shell having an open end, a closed end, and a hollow interior between the open and closed ends. A pyrotechnical material is disposed within the hollow interior, and a main explosive load is disposed within the hollow interior between the pyrotechnical material and the closed end. At least one of the pyrotechnical material or the main explosive load may be multilayered.
    Type: Application

  • Patent number: 11933589
    Abstract: According to some embodiments, a holding device for a detonation initiation system is disclosed. The holding device includes an initiator holder having a longitudinal internal cavity. The longitudinal internal cavity is configured to retain an initiator and an electrical cable in electrical contact with the initiator. The holding device further includes a plurality of retention fingers configured for retaining a shaped charge adjacent the initiator. The plurality of retention fingers define a shaped charge receiving portion that may be configured to receive shaped charges of different shapes. The holder may be formed from a thermoplastic material.

  • Patent number: 11761743
    Abstract: Embodiments of a low-voltage, non-primary explosive detonator (110) may include a detonator shell (120) having an open end (122), a closed end (124), and a hollow interior (125) between the open and closed ends. Some embodiments include a reinforcement area of the detonator shell. A pyrotechnical material is disposed within the hollow interior, and a main explosive load is disposed within the hollow interior in between the pyrotechnical material and the closed end. In some embodiments, one or both of the pyrotechnical material and the main explosive load may be multilayered, for example with a density gradient configured to accelerate deflagration. The detonator may further include a fuse head disposed at the open end and in proximity to the pyrotechnical material within the detonator shell.
