It should be emphasized that the following description is merely exemplary in nature and is not intended to limit the scope of the invention or its application. The background section of the present invention may contain background information related to the problems or the environment of the present invention and is not necessarily descriptive of the prior art. Accordingly, the inclusion in the background section is not an admission of prior art by the applicant.

An integrated transformer, as shown in fig. 1-2, comprises an insulating base 10, an upper cover copper bar 20 and two transformers (31, 32) connected in parallel, wherein the two transformers (31, 32) connected in parallel are arranged on the insulating base 10 in parallel, and the top of the transformers is covered with the upper cover copper bar 20; the upper cover copper 20 row is in limit fixed connection with the insulating base 10 through a limit fixing part 40; at least the tail end of the upper cover copper bar 20 is provided with a bending section 21 capable of increasing the heat dissipation area.

Specifically, one end of the limiting fixing component 40 is fixedly arranged on the upper cover copper bar 20, and the other end of the limiting fixing component is fixedly arranged on the insulating base 10. In this embodiment, since the upper cover copper bar 20 is made of a thin copper sheet, if there is only one fixing point, the thin copper sheet is easily torn, one end of the limiting fixing component 40 is fixed by a plurality of screws 50, so as to achieve the effect of stability, reliability and damage resistance, and the other end is fixed on the insulating base 10 by welding.
