ABSTRACT:
A circuit-breaking apparatus is formed of an insulating housing, first and second electrodes located at both ends of the insulating housing, a detonator located in the first electrode, a lead connected to the detonator for supplying an electric current to the detonator when the detonator is actuated, and a conductor disposed in the insulating housing. The conductor includes a fixed portion electrically connected to the first electrode, a circuit-breaking rod having narrow portions at both ends, and a barrel connected to the second electrode and having a cavity. The circuit-breaking rod is coupled to the fixed portion and the barrel through the narrow portions. The barrel has a locking section for locking in the cavity the circuit-breaking rod that has been shifted toward the second electrode due to cutoff of the narrow portions caused by the explosion of the detonator. Accordingly, the circuit-breaking function is surely maintained, and it can be easily determined whether a circuit-breaking operation has been performed.
