Abstract:
1. A pyromechanical cutting element comprising: a housing in which an electrical conductor is arranged; a cutting plunger with a cutting tool to cut through the electrical conductor; and a pyrotechnic charge to drive the cutting plunger, with the cutting tool bending the electrical conductor over after cutting through it and forming a bending tongue that sticks out from the conductor in a way that interrupts the conductor, wherein the electrical conductor has a cross-sectional area reduction in the longitudinal direction consisting of two transverse sides and two longitudinal sides, wherein the cutting tool is shaped to first cut through the cross-sectional area reduction of the electrical conductor just on one transverse side and, upon further advancement, bend over the longitudinal sides at least in part, and wherein, upon further advancement, the cutting tool fixedly clamps by a locking structure the bending tongue thus created.
