A method and apparatus for providing a universal plug in cartridge detonator capability in box-by-box perforating guns.

An electronic fuze for a projectile, the electronic fuze including at least one electronic board arranged in a housing of the body of the projectile, the electronic board being encapsulated in a block of protective material. The electronic board is secured to at least one support rod partially encapsulated in the block of protective material. The support rod is inserted through a hole in a wall integral with the body of the projectile, and the support rod is secured to the wall by a fastening device. A first decoupling devices is interposed between the block of protective material and the wall and a second decoupling device is interposed between the fastening device and the wall. The electronic board is located towards a front part of the projectile and the wall is located towards a rear part of the projectile.

An electronic system includes first and second circuit boards and a flexible circuit connector. The flexible circuit connector is configured to electrically connect the first and second circuit boards. The flexible circuit connector includes first and second connectors and a spiral portion. The first connector is configured to connect to the first circuit board. The second connector is configured to connect to the second circuit board. The spiral portion is connected between the first and second circuit boards and includes a circumferential portion that extends around the second connector.

A detonator to activate energetic materials in downhole well environments that can be transported and operated safely. The detonator comprises a switch coupled to a power source and the energetic materials. The power source may or may not be a part of the detonator. The switch creates a default closed switch between the power source and the energetic material. The switch can communicate with an actuator in response to engaging a gun assembly. The switch can create an open switch in response to communicating with the actuator. The switch forms a short circuit when configured to the default closed switch and forms an open circuit when configured to the open switch. The energetic material is activated in response to the mechanical switch forming an open switch and power is provided by the power source.

The invention relates to a test and/or practice ammunition having at least one projectile with a projectile head and a fin which can be found at the end of the projectile for example or a projectile with a projectile base and a projectile ogive. A cartridge shell is used to receive a drive and has a shell base, wherein an interface is attached in or on the shell base. The test and/or practice ammunition is characterized by a programmable fuze which is arranged in the projectile head or the projectile ogive. The projectile head/projectile ogive is equipped with at least one fuze amplifier and an electronic fuze system and optionally a separating charge.
