Abstract
A detonator interrupter assembly is provided. The detonator interrupter assembly is designed to inhibit the arming of a detonator within the charge tube of a perforating gun assembly. The detonator interrupter assembly first includes a top end plate. The top end plate is configured to reside between charge tubes. The top end plate has a flange intermediate first and second ends. The detonator interrupter assembly also includes a detonator clip. The detonator clip resides proximate the second end of the top end plate. The detonator clip comprises a first slot configured to receive a detonator cord, and a second slot configured to receive a detonator tube which contains an explosive material. The detonator interrupter assembly also includes an interrupter. The interrupter comprises a handle portion and an opposing blade portion. The blade portion is configured to pass through a through-opening through the flange when an operator removes the interrupter from between the first and second slots. The blade portion is fabricated from an impact resistant material.
