| 20080258855 | Transformer and manufacturing method thereof - This invention relates to a transformer and the manufacturing method thereof, wherein the primary winding is made of round-shape metal wire and the secondary winding of flat-shape metal wire, each wire being wound by the winding machine to form a coiled winding, then the two corresponding windings is formed in such a way to be cladded with magnetic material within the die, and the electrodes extending on both ends of each winding is bended to a right position such that the electrodes of the bended winding just project out of the magnetic material. In this manner, in the case the winding is used in the transformer of voltage range below 12V, not only the fabrication of transformer becomes easier and more convenient, but also the gap between the wire turns of the secondary winding is significantly reduced and thus the volume of the transformer can be shrinked. Therefore, the effectiveness in practical application of the innovative transformer and the manufacturing method thereof of the present invention is upgraded both in the entire manufacturing process and in use. | 10-23-2008 |
