ABSTRACT:
A joint for a shell with at least a first charge unit and a second charge unit arranged in series one after the other is provided. The charge units include one shaped charge each. The charges are designed to be detonated one after the other with a time separation between the detonations. In order to suppress the interference to an undetonated charge by a shock wave generated by the detonation of a previously detonated charge, the joint that connects the charge units has been designed in a special way. The joint includes a damping section parallel to the longitudinal axis of the device, that mechanically fastens together the two charge units. In addition a rigid support device is connected to the damping section and dimensioned so that when the damping section is in an unstressed state there is a clearance in the longitudinal axis of the device between the two charge units.
