Patent ID: 8514048

Claim:
A transformer having an adjustable height formed on a circuit board having a receiving hole, comprising: a winding module comprising: a winding pillar where a winding structure is formed thereon, wherein the winding pillar is received in the receiving hole of the circuit board; and a winding baseboard connected to one end of the winding pillar and parallel to the circuit board, wherein the winding baseboard comprises; a corresponding surface facing to the circuit board; and a plurality of embedding holes; two magnetic core modules contacting and holding the winding module; a plurality of pins formed on an edge of the winding baseboard to connect the winding baseboard and circuit board around the receiving hole, wherein the winding structure is further connected to the pins; and a plurality of supporting bulges formed between the corresponding surface and the circuit board, wherein each of the supporting bulges comprises an embedded structure such that the embedded structure is embedded in one of the embedded holes with an embedded depth to make the winding baseboard placed on the circuit board with the supporting bulges, the height of the corresponding surface relative to the circuit board is adjusted by turning the embedded depth and a bulge height of the supporting bulges.
