Abstract

La bobine d'allumage décrite (1), qui sert à mettre en contact des bornes (24) d'enroulements, peut être fabriquée de manière simple et économique. Un contact (33) autodénudant est fixé à demeure dans le boîtier (12) de la bobine d'allumage (11). Un corps d'enroulement (19) pourvu de l'enroulement (22) est monté sur un porte-pièce mobile (16) dans une position de prémontage. Une borne (24) de l'enroulement (22) est posée dans une poche d'assemblage (27) ménagée dans le porte-pièce (16) pour aider à fixer la borne (24). Afin de joindre la borne (24) de l'enroulement au contact (33) audénudant, on guide le contact autodénudant (33) dans la poche d'assemblage (27) jusqu'à une position de montage et on maintient en même temps la borne (24) de l'enroulement contre le contact (33) autodénudant. Une fois le contact établi avec la borne (24) de l'enroulement, le porte-pièce (16) est ramené à la position de prémontage afin de permettre la préparation d'une opération ultérieure de mise en contact. La poche d'assemblage (27) constitue un moule réutilisable qui reste sur le porte-pièce (16) et non une pièce accessoire à prévoir sur le corps (19) de l'enroulement.
