[0026] This utility model provides a transformer structure that is easy to assemble.

[0027] As Figures 1 to 6 shown, in an embodiment of this utility model, the easy-to-assemble transformer structure includes a first magnetic core 101, a second magnetic core 102, a bobbin 103, welding pins 104, and a coil winding (not shown). The first magnetic core 101 and the second magnetic core 102 are respectively detachably covered on the lower end and the upper end of the bobbin 103. The bobbin 103 includes a bottom plate 1031 and a bobbin tube 1032. Limiting flanges 1033 are respectively convexly provided on the outer peripheral walls of the upper end and the lower end of the bobbin tube 1032 along the circumferential direction. The bottom plate 1031 is respectively arranged at the lower end of the bobbin tube 1032, and the inner side walls of the bottom plate 1031 are respectively fixedly connected to the limiting flanges 1033 at the lower end of the bobbin tube 1032. Accommodating grooves 105 are respectively recessed on the inner side walls of the first magnetic core 101 and the second magnetic core 102. The bobbin tubes 1031 are respectively embedded in the accommodating grooves 105. The upper end wall and the lower end wall of the bobbin tube 1031 are respectively abutted against the inner bottom walls of the accommodating grooves 105, and the outer peripheral walls of the limiting flanges 1033 are respectively abutted against the inner peripheral walls of the accommodating grooves 105. First magnetic core columns 1011 and second magnetic core columns 1021 are respectively convexly provided on the inner side walls of the first magnetic core 101 and the second magnetic core 102. The first magnetic core columns 1011 and the second magnetic core columns 1021 are respectively embedded in the bobbin tube 1032, and the outer peripheral walls of the first magnetic core columns 1011 and the second magnetic core columns 1021 are respectively abutted against the inner peripheral walls of the bobbin tube 1032. Opening grooves 106 are respectively recessed on the two side walls of the first magnetic core 101 and the second magnetic core 102. The bottom plate 1031 respectively extends out of the outside of the first magnetic core 101, and the welding pins 104 are respectively arranged on the outside of the bottom plate 1031. The welding pins 104 are respectively fixedly connected to the bottom plate 1031. The coil winding is wound around the outer peripheral wall of the bobbin tube 1032.

[0028] Specifically, it further includes clamping brackets 107. The clamping brackets 107 are respectively detachably arranged at both ends of the first magnetic core 101 and the second magnetic core 102. The lower end and the upper end of the clamping brackets 107 are respectively detachably and fixedly connected to the lower end wall of the first magnetic core 101 and the upper end wall of the second magnetic core 102.

[0029] Specifically, a snap groove 108 is respectively recessed in the lower end wall of the first magnetic core 101 and the upper end wall of the second magnetic core 102. The upper end part and the lower end part of the clamping bracket 107 are respectively protruded with a snap arm 1071, and the snap arms 1071 are respectively detachably embedded in the snap grooves 108. In this way, the assembly and disassembly of the transformer are made more convenient and fast, facilitating later disassembly and maintenance, and being firm and reliable.

[0030] Specifically, an anti - detachment rib 1081 is respectively provided on the inner bottom wall of the front end part of the snap groove 108. The lower end wall of the front end part of the snap arm 1071 is respectively protruded with an arc - shaped limiting part 1072, and the lower end wall of the arc - shaped limiting part 1072 is respectively abutted against the inner bottom wall of the snap groove 108.

[0032] Specifically, a wire inlet groove 1034 is respectively inclined on both sides of the lower end part of the bobbin 103. In this way, it is convenient for the incoming wire of the coil winding.

[0033] Specifically, both the first magnetic core 101 and the second magnetic core 102 are formed of manganese - zinc ferrite or nickel - zinc ferrite materials. Since the ferrite magnetic core has no air gap and the cross - sectional area is consistent, the magnetic effect is very high. Ferrite is composed of iron oxide (Fe2O3) and oxides or carbonate compounds of one or several other metals (such as manganese, zinc, nickel, magnesium). The ferrite raw material is formed by pressing, then sintered at a high temperature of 1300 °C, and finally machined by a machine to make a finished magnetic core that meets the application requirements. Compared with other types of magnetic materials, the advantages of ferrite are high magnetic permeability, high resistance and small eddy current loss in a wide frequency range. The biggest characteristics of ferrite are high permeability, good temperature characteristics, and low attenuation rate.

[0034] Specifically, the bobbin 103 is formed of flame - retardant PP or flame - retardant PBT or PA66 flame - retardant nylon materials. The common characteristics of these three materials are good high - temperature resistance, good flame - retardant performance, and high hardness. The bobbin is not easy to deform, thereby ensuring the stable operation and long - term use of the transformer.

[0035] Specifically, the clamping bracket 107 is formed of SUS301 stainless steel or C5191 phosphor bronze or SK7 high - carbon steel materials. SUS301 stainless steel has good corrosion resistance and mechanical strength, C5191 phosphor bronze has good electrical conductivity and corrosion resistance, and SK7 high - carbon steel has excellent wear resistance.
