ABSTRACT:
An improved clip for holding an explosive shaped charge in a carrier strip is provided. The improved clip holds the shaped charge by inserting fingers into an annular groove formed around the perimeter near one end of the shaped charge. The clip and charge are in turn inserted into a carrier strip and held in place by notches cut into the clip. The carrier and its shaped charges are then inserted into a perforating gun tube. The carrier strip is held in position within the tube by use of spring-loaded lock pins. The lock pins are mounted on the strip so that a spring will force the pins inwardly away from the inner wall. A separate threaded screw with a cam surface is engaged to hold the lock pins in their outward position thus firmly securing the carrier strip in place.
