Abstract

Coupe-circuit pyrotechnique comprenant :- un boîtier (10), - un conducteur électrique (20) traversant le boiter (10),- au moins un couteau (31a, 31b, 31c), mobile pour couper au moins une portion du conducteur électrique (20), la coupure du conducteur électrique (20) définissant une zone coupée séparant une première extrémité coupée (21c1, 22c2, 23c2) du conducteur électrique (20) d'une deuxième extrémité coupée (22c1, 23c1, 24c1) du conducteur électrique (20),- un actionneur pyrotechnique (40),le coupe-circuit présentant un premier chemin d'arc permettant à un premier arc électrique de s’établir directement de la première extrémité coupée (21c1, 22c2, 23c2) à la deuxième extrémité coupée (22c1, 23c1, 24c1),caractérisé en ce que le coupe-circuit comprend des refroidisseurs conducteurs (51a, 52, 51b) pour présenter un chemin d’arc secondaire passant par un premier refroidisseur conducteur (51a) et par un refroidisseur conducteur secondaire (52) ou un dernier refroidisseur conducteur (51b).
