When the hooks 112 are clamped on the first frame 121 and the second frame 131, the first frame 121 and the second frame 131 are squeezed against each other, thereby preventing the main transformer 12 and the resonant inductor 13 from separating from the base 11. Through the above structure, not only the components of the transformer are reduced, but also the installation process of the transformer is simplified, the efficiency of assembling the transformer is accelerated, and the production efficiency is effectively improved.

Placing the second magnetic core 132 also facilitates winding the second coil 133 around the second skeleton 131.

[0039] Please refer to 4 and Figure 7 , Figure 4 The first frame of the transformer is easy to install. Figure 1 , Figure 7 The second frame of the transformer is easy to install. Figure 1 A plurality of through holes 1211 are provided on the first skeleton 121 and the second skeleton 131. The first skeleton 121 and the second skeleton 131 provided with the plurality of through holes 1211 are used to reduce the weight of the first skeleton 121 and the second skeleton 131, and at the same time to increase the heat dissipation of the main transformer 12 and the resonant inductor 13.

[0040] An extension plate 1212 and a third magnetic core 14 are provided on both sides of the first skeleton 121 near one end of the second skeleton 131. The extension plate 1212 is in contact with the second skeleton 131. A cavity for placing the third magnetic core 14 is formed between the first skeleton 121, the second skeleton 131, and the extension plate 1212. The extension plate 1212 is used to increase the distance between the first skeleton 121 and the second skeleton 131, thereby forming a cavity for placing the third magnetic core 14. The third magnetic core 14 is used to strengthen the magnetic lines of force of the induced current in the transformer, thereby improving the efficiency and stability of the transformer.

[0041] The base 11 is also provided with a plurality of extension columns 111 that match the barbs 112. The barbs 112 are connected to the extension columns 111. On the one hand, the extension columns 111 are used to limit the first skeleton 121 and the second skeleton 131, further stabilizing the stability of the main transformer 12 and the resonant inductor 13 connected to the base 11. On the other hand, they are used to extend the length of the barbs 112 to facilitate the barbs 112 to be snapped into the first snap-in groove 1215 and the second snap-in groove 1311.

[0042] The base 11 , the extension column 111 , and the barb 112 are all integrally formed to increase the hardness of the extension column 111 and the barb 112 , thereby further preventing the extension column 111 and the barb 112 from separating from the base 11 .

[0043] A channel for limiting the first coil 123 is provided on one side of the first skeleton 121, and a channel 1213 for limiting the second coil 133 is provided on one side of the second skeleton 131. The channel 1213 of the first skeleton 121 is used to limit the first coil 123 to prevent the first coil 123 from being scattered on the first skeleton 121, so that the first coil 123 is more beautiful when wrapped around the first skeleton 121. The channel 1213 of the second skeleton 131 is used to limit the second coil 133 to prevent the second coil 133 from being scattered on the second skeleton 131, so that the second coil 133 is more beautiful when wrapped around the second skeleton 131.

[0044] The channels 1213 are respectively located outside the first frame 121 and the second frame 131 , and are used to facilitate winding of the outgoing wire ends of the first coil 123 and the outgoing wire ends of the second coil 133 .

[0045] The base 11 is also provided with a positioning column 113 connected to the circuit board. The positioning column 113 of the base 11 is used to facilitate the installation of the base 11 on the current board. When the transformer is installed on the circuit board, it can effectively prevent the transformer from moving on the current board, making installation more convenient.

[0046] A limiting plate 1214 for limiting the third magnetic core 14 is further provided on the first skeleton 121 . The limiting plate 1214 is used to limit the third magnetic core 14 to prevent the third magnetic core 14 installed in the cavity from being separated from the transformer.

[0047] Working principle:

[0048] When assembling the transformer, first, the first coil 123 is wound around the symmetrical first skeleton 121, and the first magnetic core 122 is placed in the first skeleton 121. At the same time, the third magnetic core 14 is placed in the cavity. Due to the action of the limiting plate 1214, the limiting plate 1214 limits the third magnetic core 14. The limiting plate 1214 is used to prevent the third magnetic core 14 from moving to both sides of the first skeleton 121. Further, the second coil 133 is wound around the symmetrical second skeleton 131, and the second magnetic core 132 is placed in the second skeleton 131. The first skeleton 121 with the first magnetic ring assembly and the third magnetic core 14 installed is placed on the base 11, and the second skeleton 131 with the second magnetic ring assembly installed is placed on the base 11. The first skeleton 121 and the second skeleton 131 are both symmetrically arranged, and the extension plate 1212 of the symmetrically arranged first skeleton 121 abuts against the second skeleton 131, and the third magnetic core 14 abuts against the second skeleton 131. Finally, the hook 112 of the base 11 is clamped into the first clamping groove 1215 of the first skeleton 121 and the second clamping groove 1311 of the second skeleton 131. When the hook 112 of the base 11 is clamped into the first skeleton 121 and the second skeleton 131, the first skeleton 121 and the second skeleton 131 are squeezed against each other, and the fixation of the hook 112 can prevent the main transformer 12 and the resonant inductor 13 from separating. The above structure reduces the components of the transformer, simplifies the installation process of the transformer, speeds up the assembly efficiency of the transformer, and can effectively improve the production efficiency.

[0049] The transformer that is easy to install in this preferred embodiment is achieved by installing the first magnetic ring assembly on the first frame, installing the second magnetic ring assembly on the second frame, placing the first frame and the second frame on the base, and respectively snapping the barbs into the first snap-fit ​​groove and the second snap-fit ​​groove. The first frame and the second frame squeeze each other to prevent the main transformer and the resonant inductor from separating from the base, thereby simplifying the installation process of the transformer and effectively improving production efficiency.

[0050] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention.
