Abstract
A transformer is provided. The transformer comprises a coil frame, an input coil and an output coil. The input coil and the output coil are both disposed on the coil frame and interlaced with each other. A second voltage outputted by the output coil is induced by a first voltage inputted into the input coil. The output coil comprises at least one metal strip to enhance the output power. The coil frame is formed with a plurality of coil openings with chamfered angles or rounded angles, so that the bended angle formed by the input coil at the location where the input coil passes each of the coil openings is substantially less than 15 degrees.
Claims12
A transformer, comprising:
- a coil frame comprising a plurality of partitions, a plurality of first coil grooves and a plurality of coil openings, in which the partitions define the first coil grooves, and the coil openings are formed on the partitions and connect the first coil grooves;
- an input coil disposed on the coil frame, passing the coil openings and wound in the first coil grooves;
- and
- an output coil disposed on the coil frame and interlaced with the input coil, in which the output coil comprises at least one metallic strip, and a second voltage outputted by the output coil is induced by a first voltage inputted into the input coil, wherein the coil opening of each of the partitions is defined by two side walls, at least one of the side walls is a tapered wall having a chamfered angle or a rounded wall having a rounded angle, and a bended angle formed by the input coil at the location where the input coil passes each of the coil openings is substantially less than 15 degrees.
