Abstract
L'invention concerne un appareil de protection contre les surtensions doté d'un séparateur mécanique en cas de surcharge thermique, qui comprend des éléments de connexion pouvant être déplacés, au moyen d'un coulisseau (4), sollicité par un ressort ou précontraint, pour passer d'une position fermée à une position d'interruption du courant ou de séparation de potentiel, et la position fermée des éléments de connexion étant assurée par une soudure ou un adhésif qui peut être enlevé thermiquement. Selon l'invention, les éléments de connexion sont composés d'une paire d'étriers métalliques (1, 1') divisant le courant, dont les extrémités dirigées vers l'unité de protection contre les surtensions sont parallèles et reçoivent respectivement en leur milieu la cosse de contact (14) de l'unité de protection contre les surtensions. Les extrémités des étriers (1, 1') opposées à l'unité de protection contre les surtensions sont reliées entre elles, en délimitant un espace libre, et possèdent une partie (12) destinée à des éléments ou des bornes de connexion externes. Dans l'espace libre, le coulisseau (4) est inséré avec un ressort de précontrainte (2), la précontrainte du ressort étant orientée en direction de la cosse de contact (14) de l'unité de protection contre les surtensions. Le coulisseau (4) est cunéiforme et/ou les parties de l'étrier présentent une face oblique, afin de générer, lors du déplacement du coulisseau, une composante de force sur les extrémités des étriers parallèles pour pouvoir les éloigner de la cosse de contact. L'assemblage collé ou soudé est réalisé au niveau des extrémités des étriers parallèles et de la cosse de contact.
