Abstract
An initiator includes a pair of electrodes, an insulating member interposed between the pair of electrodes, a cover body covering one end side of the pair of electrodes together with a space around the pair of electrodes, and an explosive with which the space inside the cover body is filled. The pair of electrodes include, in the space, a discharge gap where a dielectric strength is lower than a dielectric strength of a portion where the insulating member is interposed. In this way, provided is a technology that enables ignition without a bridge wire and facilitates manufacture of an initiator.
Claims20
An initiator comprising:
- a pair of electrodes;
- an insulating member interposed between the pair of electrodes;
- a cover body covering one end side of the pair of electrodes together with a space around the pair of electrodes;
- and
- an explosive with which the space inside the cover body is filled, wherein
- the pair of electrodes include, in the space, a discharge gap where a dielectric strength is lower than a dielectric strength of a portion where the insulating member is interposed.
A method for manufacturing an initiator, the method comprising:
- integrating a first electrode and a second electrode with an insulating member interposed between the first electrode and the second electrode to form an electrode unit with a discharge gap between the first electrode and the second electrode;
- filling an explosive accommodation portion in a cover body having a bottomed tubular shape with an explosive from an opening of the cover body;
- fitting the electrode unit into the opening of the cover body such that the discharge gap of the electrode unit is brought into contact with or close to the explosive with which the cover body is filled;
- and
- integrally joining the cover body and the electrode unit.
