  • Detonating assembly with U-bend of low energy detonating cord
    Patent number: 4539909
    Abstract: A non-electric detonator assembly is provided for initiation by means of a connected length of low energy detonating cord. The assembly comprises a substantially conventional instantaneous or delay period non-electric blasting cap containing a detonating cord attachment plug element in its open end. The plug element is adapted to receive a secured bend of low energy detonating cord and to transmit initiating energy from the cord to the cap. Use of the assembly allows for the convenient assembly of the cord/cap combinations in the field and eliminates wasted cord.
