Transformer structure

Abstract

The present invention is a transformer structure, which includes: primary winding; secondary winding; first winding part, which is used to wind primary winding; second winding part, which is respectively used to wind secondary winding Wire; a spacer plate, which is respectively arranged between the first winding part and the second winding part, and has an accommodating part; a penetrating part, which runs through the first winding part, the second winding part and the spacer plate The iron core group includes an I-shaped iron core and a U-shaped iron core. There are multiple protrusions between the two sides of the U-shaped iron core. The I-shaped iron core is partially accommodated in the through portion, and the U-shaped iron core The protruding part is inserted into the accommodating part of the spacer plate, and the leakage inductance of the transformer is adjusted by the distance between the protruding part of the U-shaped iron core and the I-shaped iron core accommodated in the penetrating part.

Description

technical field [0001] The invention relates to a transformer structure, especially a transformer structure capable of increasing leakage inductance. Background technique [0002] Transformers are electronic components often used in various electrical equipment. see figure 1 , which is a schematic structural diagram of a traditional transformer. Such as figure 1 As shown, the transformer 1 mainly includes an iron core set 11 , a winding base 12 , a primary winding 13 , a secondary winding 14 and the like. Wherein, the primary winding 13 and the secondary winding 14 are wound up and down in the winding area of ​​the winding base 12 , and are insulated and separated from each other by an adhesive tape 15 . The core group 11 can set the axis 111 in the casing 121 of the winding base 12, so that the core group 11, the primary winding 13 and the secondary winding 14 generate electromagnetic coupling induction, so as to achieve the purpose of voltage conversion .

Problems solved by technology

[0010] The main purpose of the present invention is to provide a transformer structure, which separates the primary winding and the secondary winding by a spacer, or separates the primary winding and the secondary winding on different sides of the body. To increase the distance between the primary winding and the secondary winding to increase the leakage inductance of the transformer, and then adjust the leakage of the transformer by the distance between the protruding part of the U-shaped iron core and the I-shaped iron core In order to increase the electrical safety, and solve the problems in the prior art, the electrical safety distance of the transformer structure is insufficient, the production is time-consuming and laborious, and the tape is easy to deteriorate.
