[Prior Art] Press, the transformer is a necessary component in the electronic circuit, and has different safety requirements depending on the purpose. In the safety regulations of countries all over the world, the creepage distances between the primary side and the secondary side are specified. The creepage distance has a minimum safety distance according to the safety level. If the creepage distance is less than the specified value, then There is a danger of short-circuit between the primary and secondary sides. Conventional transformers are usually provided between the primary side coil (first coil) and the secondary side coil (second coil). A separator 1 must have a sufficient creepage distance to ensure the primary and secondary sides. There is no danger of short circuit between them. However, the increase in the thickness of the separator increases the overall height of the transformer, which is difficult to meet the requirements for thinning modern electronic products. The reason is that this creator feels that the above-mentioned deficiencies can be improved. He is devoted to research and using the theory, and finally proposes a creation that is reasonable in design and effective in improving the above-mentioned defects.
