Abstract

L'invention concerne un procédé de fabrication d'une bobine d'allumage individuel pour une bougie (2) de moteur thermique à combustion interne et à allumage commandé, comportant les étapes suivantes : bobinage d'un enroulement secondaire (15) sur un corps tubulaire de bobine secondaire (11), bobinage d'un enroulement primaire (23) concentriquement et extérieurement par rapport à l'enroulement secondaire (15) en étant isolé électriquement par rapport à ce dernier à l'aide d'un matériau diélectrique. Selon l'invention, il comporte une étape de surmoulage de l'ensemble corps tubulaire (11) enroulement secondaire (15) par un matériau diélectrique assurant une imprégnation de l'enroulement secondaire et la formation d'une part d'un corps tubulaire de bobine primaire (21) adapté pour permettre lors d'une étape ultérieure, le bobinage de l'enroulement primaire (23), et d'autre part, d'un embout de raccordement (211) à une bougie prolongeant le corps tubulaire de bobine primaire (21) à l'une de ses extrémités.
