Transformer structure

Abstract

The invention relates to a transformer structure which comprises a winding base, a primary winding, a secondary winding, a cover body and a magnetic core group, wherein the winding base comprises a body and is provided with a first winding area, a second winding area, a first buckling component and a passage; the passage runs through the body; the primary winding is wound on the first winding area of the winding base; the secondary winding is wound on the second winding area of the winding base; the cover body covers on at least a part of the winding base and is provided with a second buckling component corresponding to the first buckling component; and the magnetic core group is partially arranged in the passage of the winding base.

Description

technical field [0001] The invention relates to a transformer structure, in particular to a transformer structure capable of extending the electrical safety distance between a winding wire and a magnetic core group. Background technique [0002] Transformer is a magnetic component often used in various electrical equipment. It uses the principle of electric energy and magnetic energy conversion induction to adjust different voltages to make it reach the applicable range of electrical equipment. [0003] see figure 1 , which is a structural schematic diagram of an existing transformer. As shown in the figure, the transformer 1 includes a winding base 11 (bobbin), a cover 12 (cover) and a magnetic core assembly 13 (magnetic core assembly), wherein a primary winding coil 111 (primary winding coil) and a secondary winding coil 112 (secondary winding coil) is wound on the winding base 11, as for its outlet ends 113, 114, then directly wound and welded on the pin 115 extending v...

Problems solved by technology

[0005] The main purpose of the present invention is to provide a transformer structure, which has a cover, a winding base, primary windings and secondary windings wound on the winding base, and a magnetic core group, and the cover covers at least Part of the winding base to solve the problems of poor heat dissipation and temperature rise of the existing transformer due to the blockage of the cover

[0006] Another object of the present invention is to provide a transformer structure, wherein the winding base and the cover have corresponding engaging parts to extend between the primary winding and the secondary winding and between the primary winding and the secondary winding. The creepage distance between the wire and the magnetic core group is used to solve the problem that the existing transformer has a larger volume due to the extension of the two ends of the cover in order to maintain the electrical safety distance.
