Abstract
In an exposed perforating gun assembly, contact with well fluids at high pressure and temperature is detrimental to explosives in the explosive train. This device protects such explosives and includes a cylindrical housing with a bore having an electrical feedthrough at one end, an enclosed initiator, a cooperative sleeve and cooperative sealed retainer. The detonating cord is sealed into proximity with the initiator and is held against high pressure extrusion by the sealed retainer.
