Patent ID: 7612643

Claim:
An improved winding structure of a transformer, wherein the transformer comprises a winding base externally set with a first isolating plate and a second isolating plate, the transformer is divided into two primary side regions and a secondary side region by the first isolating plate and the second isolating plate, in which the secondary side region is divided into a plurality of winding grooves by a plurality of partitions for placing a wire in the grooves with two ends of the wire affixed on connectors respectively, wherein one of the connectors is disposed on one end of the first isolating plate and another one of the connectors is disposed on one end of the second isolating plate, wherein the connectors each has a longitudinal axis perpendicular to a longitudinal axis of the secondary side region, at least two pre-formed wire sets each is coupled to one of the two primary side regions, in that each of the two primary side regions has a winding reel to sleeve on the pre-formed wire sets.
