Abstract
An initiator is provided for use with an initiator holder. The initiator comprises a can; at least two electrodes; an explosive charge positioned to be ignited when electrical charge is passed through said electrodes; and a body portion surrounding the electrodes. The body portion may have a first portion with a first cross-sectional area and a second portion having a second cross-sectional area, wherein the second cross-sectional area has a shape different from the first cross-sectional area and wherein the second cross-sectional area is less than 40% of the first cross-sectional area; wherein the second portion is shaped to extend outward from an opening in the holder when the body portion is seated in the holder.
Claims27
An initiator for use with an initiator holder, said initiator comprising:
- a can;
- at least two electrodes;
- an explosive charge positioned in the can and configured to be ignited when electrical charge is passed through said electrodes;
- and
- a body portion surrounding at least a portion of said electrodes, said body portion having a first portion with a first cross-sectional area and a second portion having a second cross-sectional area, said first cross-sectional area measured at the interface with the second portion;
- said second cross-sectional area having a shape different from said first cross-sectional area and wherein said second cross-sectional area is less than 40% of said first cross-sectional area;
- wherein said second portion is shaped to extend outward from an opening in the holder when the body portion is seated in the holder.
An initiator for use with a holder, said initiator comprising:
- a can;
- at least two electrically conductive pins;
- an explosive charge configured to be ignited when electrical charge is passed through said pins;
- and
- a body having a first portion with a circular cross-section relative to a longitudinal axis of the initiator and a second portion having a rectangular cross-section relative to a longitudinal axis of the initiator.
An initiator for use with a holder, said initiator comprising:
- a can;
- a plurality of electrodes;
- an explosive charge configured to be ignited when electrical charge is passed through said electrodes;
- and
- means for supporting and positioning said plurality of electrodes, wherein at least a portion of said means extends outward from the holder when the means are seated against the holder.
An initiator holder comprising:
- a housing with an inner surface and an outer surface, said inner surface having a shape to receive an initiator body having a first portion and a second portion;
- an opening on said housing, said opening sized and shaped to receive the second portion of the initiator body, an area of said opening being less than 40% of an cross-sectional area of the first portion of the body, said first cross-sectional area measured at the interface with the second portion.
