Abstract

L’invention concerne un dispositif de sécurité à déclenchement thermique qui comporte : - une cage munie d’un passage transversal prévu pour être traversé par un élément à sectionner, le passage transversal comportant au moins une arête tranchante, - un coulisseau coulissant dans la cage, - un élément élastique de rappel qui sollicite le coulisseau en direction de l’appui contre l’élément à sectionner, - une unité de déclenchement thermique qui est agencée de manière à retenir le coulisseau dans sa position axiale de repos, lorsque la température locale est inférieure ou égale à une température de seuil, et de manière à libérer le coulisseau lorsque la température locale dépasse la température de seuil. Figure pour l’abrégé : figure 1The invention relates to a safety device with thermal tripping which comprises: - a cage provided with a transverse passage intended to be traversed by an element to be severed, the transverse passage comprising at least one cutting edge, - a sliding slider in the cage , - an elastic return element which urges the slider in the direction of bearing against the element to be severed, - a thermal release unit which is arranged so as to retain the slider in its axial rest position, when the local temperature is less than or equal to a threshold temperature, and so as to release the slider when the local temperature exceeds the threshold temperature.
