FIELD: instrument engineering.
SUBSTANCE: group of inventions is intended for assembly of cumulative perforators and can be used in cumulative perforators. Method of cumulative charge fixation in perforator carcass consists in installation of cumulative charge in holes made on diametrically opposite sides of perforator carcass, located in frame along helical line with angle X and pitch Y, installation in these holes of fixing elements, which are installed by means of projections located on them. Installation of each fixing element is carried out by its movement along axis of holes on the side of hole having rectangular slots, before contact with outer surface of frame so that protrusions get into slots and fixing element turn around its axis.
EFFECT: higher reliability of detonation transmission from detonating cord to charge due to attachment method.
