Abstract

L'invention concerne un agencement de commutation électromécanique modulaire avec une partie d'actionneur (10) qui est prévue dans un carter métallique (12), avec une partie de convertisseur (20) qui est prévue dans un carter de convertisseur (22) qui comprend un élément de liaison plan (26) en matière plastique. L'agencement comprend en outre un module de commande (30) qui est prévu dans un carter (32) en matière plastique. Le carter métallique (12) de la partie d'actionneur (10) est relié au carter de convertisseur (22) par une première liaison mécanique durable (40). Le carter de convertisseur (22) est relié à l'élément de liaison plan (26) en matière plastique par une deuxième liaison mécanique durable (50). Le carter (32) en matière plastique du module de commande (30) est relié à la partie de convertisseur par une liaison mécanique amovible (50). Enfin, le carter (32) en matière plastique du module de commande (30) est immédiatement juxtaposé à l'élément de liaison plan (26) en matière plastique et est séparé du carter métallique (12) de la partie d'actionneur (10). En variante, le carter de convertisseur possède un deuxième élément de liaison plan (23). Les éléments de liaison plans (24, 26) peuvent être formés d'une seule pièce avec le carter de convertisseur. Une liaison amovible (40, 50) n'est autorisée, selon l'invention, que si les éléments de liaison plans (24, 26) sont du même matériau que le carter (12, 32) d'actionneur ou du module de commande (10, 30). L'invention concerne en outre un procédé correspondant pour la liaison de modules dans un agencement de commutation électromécanique modulaire.
