Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] Such as figure 1 shown, see also figure 2 and image 3 , a transformer provided by an embodiment of the present invention includes a ring-shaped closed iron core 10, a ring-shaped skeleton 20 is surrounded on the wall 11 of the annular closed iron core 10, and the ring-shaped skeleton 20 is an insulating skeleton and The number is at least four, and the outer surface of each ring frame 20 is wound with a wire to form a coil.

[0027] see figure 1 Compared with the prior art, the embodiment of the present invention arranges an insulating ring frame 20 on the ring-shaped closed iron core 10, and uses the structure of the ring frame 20 to wind and support the coil, so that the existing traditional winding machine can be used to...

Abstract

The invention discloses a transformer and belongs to the field of electronic products. The transformer comprises an annular closed iron core; an annular framework is encircled on the wall of the annular closed iron core; at least four annular frameworks serving as insulation frameworks are provided; and a wire is coiled on the outer surface of each of the annular frameworks so as to form a winding. As the windings of the transformer are coiled on the annular frameworks, the coiling is easy to realize, the processing difficulty is reduced, the production efficiency is improved and the product cost is reduced; and as at least four annular frameworks are arranged on the transformer and set to be primary windings and secondary windings as required, the heat dissipation effect is good and the performance of the transformer is guaranteed effectively. Furthermore, by the transformer, the two difficulties of the conventional transformer are reduced basically, so the transformer is easy to popularize.

Description

technical field [0001] The invention relates to electronic products, in particular to a transformer. Background technique [0002] Transformer is a kind of electrical equipment used for electric energy conversion, which can convert AC energy of one voltage and current into AC energy of another voltage and current of the same frequency. [0003] Among electronic transformers, the traditional toroidal transformer is a transformer with a relatively reasonable structure, which includes a ring-shaped closed iron core, a first insulating layer wrapped on the surface of the closed iron core, and a primary winding wound on the first insulating layer. A coil, a second insulating layer wrapped on the primary coil, and a secondary coil wound on the second coil. [0004] The inventor finds that the prior art has the following problems in the process of realizing the present invention: [0005] First, since the iron core of the existing toroidal transformer is a closed ring, and both t...
