Abstract
An integrated detonation assembly of a perforating unit includes a detonator assembly and a charge assembly. The detonator assembly is positioned in the outer housing and comprises a bulkhead connected to the outer housing; a charge connector connected to the bulkhead, the charge connection having a connection end; a detonator carried by the charge connector; and a trigger coupled to the detonator and to a remote actuator. The charge assembly is insertable into the outer housing, and comprises a charge tube to support shaped charges therein; a charge feedthru; and a receiver. The receiver is at an opposite end of the charge tube, and has a receptacle shaped to matingly receive the connection end of the charge connector and to engage the trigger whereby, upon insertion of the charge assembly into the outer housing, the receiver is oriented and communicatively secured to the detonator assembly.
