The primary side coil and the secondary side coil are formed by layer-by-side winding to increase the inductive coupling property, and an insulating film is disposed between the coils of each layer side to avoid A short circuit is generated, and the layer winding method can eliminate the configuration of winding around the hollow tubular mold, so that the whole design can achieve high efficiency and simplification. [Prior Art] According to the 'conventional conventional transformer, an enameled wire of the same or different wire diameter is wound on a bobbin to form a primary side coil and a secondary side coil, and then a core is placed in the winding shaft for sensing. Lightly combined to generate an induced electromotive force for use by an external circuit. And because of the safety requirements, the coil must be separated from the side edge of the winding body by a Creepage distance, that is, the shortest between the conductive element (coil) and the object interface (the side edge of the winding body) via air separation. Straight line distance. In order to increase the overlapping area between the coil layers to increase the inductive coupling between the coils on each side, the coil winding process or the structure of the winding shaft is improved; by definition and principle, the path through which the magnetic flux passes Known as the magnetic circuit, the resistance generated by the magnetic field against the magnetic flux is called the magnetoresistance (R). The force required to pass the magnetic flux on the magnetic path is called the magnetomotive force (F). According to Ohm's law, 0 = F /R and magnetoresistance formula / (/ / A) can be found: the magnetic resistance (R) and the magnetic circuit length (/) are positive 3 M425377 ratio, and the magnetic circuit cross-sectional area (A) and magnetic permeability coefficient (to) The product is inversely proportional, and the excessive magnetic reluctance will cause the copper loss of the enameled wire and the iron loss of the core to cause the entire transformer to overheat, resulting in unavoidable power loss. Therefore, effectively reducing the length of the magnetic circuit of the transformer and increasing its cross-sectional area is a bottleneck for the current transformer design. In view of this, the creator feels that he has not perfected his mind and tried his best to study 'and through his years of accumulated experience in the industry, and then developed a layer-wound transformer' to form a hollow by layer winding. The part is inserted to the core, which not only simplifies the use of the material but also the manufacturing process. The windings formed by the winding method are separated by an insulating film to avoid short circuit. This method greatly shortens the magnetic path length of the transformer. As a result of the layer stacking, the cross-sectional area of the magnetic circuit is also increased, and the inductive coupling is optimized, which improves the efficiency of the overall transformer. [New content] In order to solve the above problems, the purpose of the present invention is to provide a layer-wound transformer which, after forming a space by a layer winding method, is provided with a magnetic circuit distribution which is inserted and closed, which not only simplifies the use of materials but also Lower _ # L i «3 • In the above process, the coupling coil layer I, Α7 formed by the layer winding method is separated by an insulating film to avoid short circuit ^ ' this side - V' i The type of the magnetic circuit of the transformer is greatly shortened, and the layer is wound around the stack, and the cross-sectional area of the magnetic circuit is also added to optimize the inductive coupling, thereby improving the overall performance of the transformer and eliminating the need to provide a hollow tube. "There is a setting for the winding table, which greatly simplifies the overall change.
