Problems solved by technology
[0008] However, as can be seen from the above-mentioned transformer structure and assembly method, the traditional transformer outlet method needs to use a lot of tapes and gaskets, so the structure is relatively complicated and the cost is high.
In addition, due to the need to repeat the action of covering the tape and the gasket, it is difficult to carry out and the productivity cannot be improved.
In addition, since the winding ends (copper wires) need to be soldered to their corresponding copper wires, the quality of the transformer will also be reduced due to the problem of solder joint puncture.
Moreover, the copper wire with polyvinyl chloride (PVC) as the insulating film will limit the overall temperature resistance of the transformer due to the low melting point of PVC (about 105 degrees).
Furthermore, since the free end of the copper wire cannot be directly fixed to the printed circuit board, additional materials and actions such as fixed terminals are required, which not only causes waste of materials, but also increases the number of steps in the manufacturing process, which only increases the production cost and reduces the cost. Productivity of the production process

Embodiment Construction
[0051] Transformer structure of the present invention, such as image 3 As shown, it includes a magnetic core assembly 4, a winding base 5, a primary winding coil (not shown), a secondary winding coil (secondary winding coil) (not shown) and Housing 6 etc. Wherein, the primary winding and the secondary winding are respectively wound on the winding base 5 , and generate electromagnetic interaction through the core set 4 to achieve the purpose of voltage conversion. The core group 4 is usually an EI-type core group (EI-core) or an EE-type core group (EE-core), and the housing 6 includes a housing base 61 and a cover plate 62. When the housing base 61 and the cover plate 62 When combined, the core set 4 and the winding base 5 can be fixed to form the main body of the transformer. Of course, the transformer can also be fixed to the housing of the electrical equipment or a printed circuit board (not shown) according to the requirements of the conditions, or the transformer can al...
