Transformer winding structure, has secondary-winding coil with extension section that extends in direction set against transformer and links with power-connection section having pin and extends contact area with air

摘要

The structure has a core (32) with a primary-winding coil and a secondary-winding coil. The secondary-winding coil has an extension section (353), which is connected with a winding end of a winding area (351). The extension section extends in a direction or protrudes from a direction, which is set against a transformer (3). The extension section is connected with a power-connection section (354), which consists of a contact pin (355) or connection that is electrically connected with a printed circuit board. The extension-section extends a connecting or contact area with the air.
