ABSTRACT:
The invention relates to a pyromechanical disconnecting device having a housing (2) in which an electrical conductor (3) is arranged, having a cutting plunger (5) and a cutting chisel (8) made of plastic arranged thereon for severing the electrical conductor (3), and having a pyrotechnic igniter (1) in which a pyrotechnic charge is arranged for driving the cutting plunger (5), the cutting chisel (8) having an edge that slides along a mating edge of the housing (2) or of a component (4) of the housing (2) when the cutting plunger (5) or the cutting chisel (8) is driven and when the electrical conductor (3) is severed.In order to achieve better cutting power, it is proposed that the edge of the cutting chisel (8) and/or the mating edge of the housing (2) or of a component (4) of the housing (2) comprise an inserted structural element (6, 7) having a greater hardness than plastic.
