Abstract

L’invention se rapporte à un dispositif (10) de commande d’un contact mobile (91) relativement à un contact fixe d’une ampoule à vide (90) d’un appareil de connexion électrique (100). Ce dispositif (10) comprend un mécanisme principal d’ouverture et de fermeture (1, 2, 3, 4) des contacts, du type à accumulation d’énergie mécanique. Selon l’invention, ce dispositif (10) comprend un mécanisme auxiliaire d’aide à l’ouverture (5, 6, 7, 8) agencé pour accumuler de l’énergie mécanique lorsque le contact mobile (91) est déplacé vers la position de fermeture, et pour restituer l’énergie mécanique ainsi accumulée de manière à exercer un effort d’ouverture additionnel sous forme de choc tendant à déplacer le contact mobile (91) de la position de fermeture vers la position d’ouverture lorsque le contact mobile (91) est bloqué dans la position de fermeture malgré l’action de l’effort d’ouverture principal. Cet effort d’ouverture additionnel peut en particulier être transmis par un bras de frappe (6) entraîné en rotation sous l’action d’un ressort d’ouverture auxiliaire (5) jusqu’à venir frapper avec l’une de ses extrémités un levier (41) du mécanisme principal, ou une pièce reliée à ce levier (41).
