Abstract

The invention discloses a planar transformer and a power adapter and relates to the technical field of transformers. The planar transformer comprises a first magnetic core, a second magnetic core, a winding, a first fixing device and a second fixing device, the first magnetic core and the second magnetic core are oppositely arranged, the winding is arranged between the first magnetic core and thesecond magnetic core, the first magnetic core is arranged between the first fixing device and the winding, the first magnetic core is arranged between the winding and the first fixing device, the second magnetic core is arranged between the winding and the second fixing device, the first fixing device is provided with a clamping groove, the second fixing device is correspondingly provided with a clamping hook matched with the clamping groove, the winding is provided with a limiting through hole, and the clamping hook can penetrate through the limiting through hole to be clamped in the clampinggroove, so that the second fixing device and the first fixing device can be locked. The power adapter comprises the planar transformer. According to the planar transformer, the problem that the two magnetic cores are not tightly attached can be solved, and then the stability of the planar transformer is improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a planar transformer and a power adapter. Background technique [0002] A transformer is a static electrical device that transforms voltage or current between two or more windings at the same frequency by means of the principle of electromagnetic induction. A traditional wound transformer generally includes a coil support made of insulating material, a coil wound on the coil support and an iron core wrapped outside the coil. With the rapid development of science and technology, power electronic equipment continues to develop in the direction of smaller volume, higher power density and higher efficiency. As one of the key components in power electronic equipment, transformers also tend to be lightweight. As a result, the size of the transformer is also required to be relatively reduced, so that the demand for planar transformers is increasing day by day. [0003] However, i...
