Abstract
A detonator assembly is provided which is usable at high temperatures about 300.degree. C. A detonator body is provided with an internal volume defining an anvil surface. A first acceptor explosive is disposed on the anvil surface. A donor assembly having an ignition element, an explosive material, and a flying plate, are placed in the body effective to accelerate the flying plate to impact the first acceptor explosive on the anvil for detonating the first acceptor explosive. A second acceptor explosive is eccentrically located in detonation relationship with the first acceptor explosive to thereafter effect detonation of a main charge.
Claims17
A detonator assembly, comprising:
- body means defining an anvil surface;
- a first acceptor explosive disposed on said anvil surface;
- donor means, including a donor explosive for effecting an impact on said first acceptor explosive on said anvil for detonation;
- and
- a second acceptor explosive in detonation relationship with said first acceptor explosive.
In a detonator assembly having a donor explosive for detonating an acceptor explosive in a detonator body, an improvement comprising:
- an anvil surface defined symmetrically about an axis within said body, a first portion of said acceptor explosive disposed on said anvil surface and
- flying plate means for impacting said first portion of said acceptor explosive on said anvil surface.
A method for detonating an assembly of donor and acceptor explosives comprising the steps of:
- disposing a first acceptor explosive on an anvil surface perpendicular to an axis of said assembly;
- and
- igniting said donor explosive to effect an impact on said first acceptor explosive against said anvil surface with a force effective to detonate said first acceptor explosive.
