Abstract:
1. A bobbin for an inductive electronic component having a coil, the electronic component including a transformer core positioned in the bobbin, the transformer core forming an air gap, the bobbin comprising: a magnetically conductive member that defines a winding surface for winding the coil; and a partition transversely extending from the winding surface, the partition separating the winding surface into a first winding surface region and a second winding surface region, the partition defining a passage for winding the coil from the first winding surface region to the second winding surface region and defining a first passage opening into the passage at the first winding region and a second passage opening into the passage at the second winding region, the passage openings being positioned relative the winding surface so that the partition separates the first passage opening from the second winding region and the partition separates the second passage opening from the first winding region, the passage being axially positioned over the air gap in the transformer core.
