Abstract
An apparatus and a method to initiate a detonation utilizing an impact switch. A nose assembly is mounted upon a missile or other kind of explosive device. Within the nose assembly conductive elements are separated from one another. The conductive elements are electrically connected to a fuze within the weapon. Upon an impact, the conducting elements within the assembly are forced together thereby completing a circuit in the fuze and initiating a detonation. A method of initiating a detonation utilizes an impact switch within which forcing conducting elements together initiates a detonation.
Claims10
An impact switch comprising:
- a nose assembly a having nose bottom and a nose top that are substantially hollow;
- said nose bottom having an extended section that is dimensioned and configured to reside within said nose top, said extended section of said nose bottom being constructed of insulating material;
- a conducting bottom ring having an inner diameter larger than the diameter of at least a portion of said extended section, the conducting bottom ring being connected to said nose bottom and positioned upon said extended section of said nose bottom such that at least a portion of said extended section passes through said conducting bottom ring, said conducting bottom ring being connected to an end of a first conductor of a fuze;
- a conducting top ring having an inner diameter larger than the diameter of at least a portion of said extended section, the conducting top ring being positioned adjacent to said nose top and positioned upon said extended section of said nose bottom such that at least a portion of said extended section passes through said conducting top ring, said conducting top ring being connected to an end of a second conductor of said fuze;
- an insulating spacer ring positioned between said conducting top ring and said conducting bottom ring;
- wherein said nose top and said nose bottom are fixedly connected to one another;
- and
- wherein upon an impact said bottom ring and said top ring contact one another to form an electrical connection between said first conductor and said second conductor.
A method for initiating a detonation comprising:
- providing an impact switch having a nose assembly having a nose bottom and a nose top that are substantially hollow wherein said nose bottom has an extended section that is constructed of insulating material and dimensioned and configured to reside within said nose top, wherein a conducting bottom ring having an inner diameter larger than the diameter of at least a portion of the extended section is connected to said nose bottom and positioned upon said extended section of said nose bottom such that at least a portion of the extended section passes through the conducting bottom ring, wherein said conducting bottom ring is fixedly connected to a first conductor of a fuze, wherein a conducting top ring having an inner diameter larger than the diameter of at least a portion of said extended section positioned adjacent to said nose top and positioned upon said extended section of said nose bottom such that at least a portion of the extended section passes through the conducting top ring, wherein said conducting top ring is fixedly connected to a second conductor of said fuze, wherein an insulating spacer ring is positioned between said conducting top ring and said conducting bottom ring, wherein said nose top and said nose bottom are fixedly connected to one another;
- and
- subjecting said impact switch to an impact sufficient to cause said bottom ring and said top ring to contact one another to form an electrical connection between said first conductor and said second conductor, thereby closing an electrical circuit to initiate a detonation.
