Abstract

The invention provides a transformer, which comprises a magnetic core assembly, a primary winding and a secondary winding, wherein the primary winding and the secondary winding are wound on the magnetic core assembly and are matched with the magnetic core assembly to be used, the primary winding comprises a first winding and a second winding, the first winding is coupled with the secondary winding in the axial direction, the second winding is coupled with the secondary winding in the radial direction, and / or the secondary winding comprises a third winding and a fourth winding, wherein the third winding is coupled with the primary winding in the axial direction, the fourth winding is coupled with the primary winding in the radial direction. Through the technical scheme of the transformer, the primary winding and the secondary winding in the transformer can be coupled in both the axial direction and the radial direction, in addition, the production cost of the transformer is reduced, and the heat radiation effect of the transformer is optimized.

Description

technical field [0001] The present invention relates to the technical field of transformers, in particular to a transformer. Background technique [0002] A high-frequency heating device such as a step-up transformer used in a magnetron drive is mainly composed of a winding shaft, a primary winding and a secondary winding arranged on the winding shaft, and at least two magnetic cores inserted into the winding shaft to form a magnetic circuit, such as Consists of two U-shaped cores or one U-shaped core and one I-shaped core. [0003] In the related art, the commonly used structure of the transformer is the primary winding, and the secondary winding is coaxially arranged on both sides of an insulator, and usually the primary winding and the secondary winding are arranged on the same arm of the U-shaped magnetic core. Above, this wire-wound magnetic core arm, another magnetic core arm, and the connection between the two arms form the magnetic circuit required for the transform...
