The bobbin includes tubular winding core and a plurality of fins substantially perpendicular to the axis of the core. The fins defining between them annular winding compartments of which the core forms the bottom. Each fin including a passage to allow the secondary winding wire to pass, in the winding direction, from the compartment located upstream of this fin to the compartment located downstream. The core has a shape such that the passage opens into the upstream compartment at a distance (e) from the bottom of the core and into the downstream compartment level with the core.
