HIGH TEMPERATURE HIGH PRESSURE DETONATOR For use in a perforating gun assembly typically lowered on an electric wireline or on tubing into a wellbore exposed to high pressure and high temperature, an apparatus is set forth which includes an elongate cylindrical housing cooperative with detonating cord. It has a side port or window to enable the detonating cord to be folded slightly into it. The housing includes a cavity for receiving required explosives and connection with an ignitor. This arrangement enables the housing to connect with the detonating cord and overcome high pressure or high temperature difficulties. This will accommodate detonating cords of different sizes and shapes and with differing types of covering materials.
