Abstract

L'invention concerne un dispositif de coupure pyrotechnique (100) comprenant : une première chambre (14) en communication avec un initiateur pyrotechnique (20), une deuxième chambre (15) délimitée par un support (50) sur lequel est présente une portion conductrice (40), le support définissant un premier (51) et un deuxième (52) logements distincts, et un piston (30) comprenant un premier (34) et un deuxième (35) reliefs de coupure situés en regard du premier et du deuxième logements, l'initiateur pyrotechnique étant configuré pour faire passer le dispositif de coupure d'une première configuration de passage du courant à une deuxième configuration de coupure du courant, le piston étant mis en mouvement afin de rompre la portion conductrice par impact avec les reliefs de coupure, chaque relief de coupure présentant, dans la deuxième configuration, une face (34a, 35a) en contact avec le support. Le piston comprend en outre un relief additionnel (36) en saillie entre le premier et le deuxième reliefs de coupure, et le support comprend en outre un troisième logement (53) dans lequel se loge le relief additionnel dans la deuxième configuration.The invention relates to a pyrotechnic switching device (100) comprising: a first chamber (14) in communication with a pyrotechnic initiator (20), a second chamber (15) delimited by a support (50) on which a conductive portion is present (40), the support defining a first (51) and a second (52) separate housing, and a piston (30) comprising a first (34) and a second (35) cut reliefs located opposite the first and the second housings, the pyrotechnic initiator being configured to pass the cut-off device from a first current flow configuration to a second current cut configuration, the piston being set in motion in order to break the conductive portion by impact with the reliefs of cut, each cut relief having, in the second configuration, a face (34a, 35a) in contact with the support. The piston further comprises an additional relief (36) projecting between the first and second cut reliefs, and the support further comprises a third housing (53) in which the additional relief is housed in the second configuration.
