The invention provides a transformer structure, which comprises a bobbin bracket, a shell and a magnetic core set, wherein the bobbin bracket is provided with a winding part, a penetrating channel and a plurality of grounding pins, wherein the winding part is used for winding a primary winding and a secondary winding; the penetrating channel penetrates the winding part; the plurality of groundingpins penetrate a part of the bobbin bracket and protrude a first end part respectively; the shell is provided with an accommodating part, the penetrating channel communicated with the accommodating part and a plurality of penetrating holes, wherein the accommodating part is used for accommodating a part of the bobbin bracket so as to ensure that the shell is communicated with the penetrating channel of the bobbin bracket; the plurality of penetrating holes and the plurality of grounding pins are correspondingly arranged so that the first end part of each grounding pin is protruded outside of the shell through the corresponding penetrating hole; and the magnetic core set is partially inserted into the bobbin bracket and the penetrating channel of the shell and partially contacted with the plurality of first end parts of the plurality of grounding pins protruded outside of the shell.
Description
technical field [0001] The invention relates to a transformer structure, especially a transformer structure which is simple in structure and easy to assemble, and when the magnetic core group is arranged on the winding frame, it will be in contact with the grounding pin on the winding frame to reduce electromagnetic interference. Background technique [0002] Transformers are electronic components often used in various electrical equipment to adjust different voltages to the applicable range of electrical appliances. see figure 1 , which is a schematic structural diagram of a traditional transformer. As shown in the figure, the transformer 1 includes a magnetic core set 11, a winding frame 12, a primary winding 13, a secondary winding 14 and an insulating tape 15, wherein the winding frame 12 has a first side plate 121 . A second side plate 122 and a winding portion 123 . The insulating tape 15 is wound substantially at the center of the winding portion 123 to divide the ...
