The seat body covers a part of the iron core group and is located between The iron core group and the electronic device. In addition, the transformer is erected on the electronic device and has a certain height.

Nowadays, electronic products tend to be thinner and more flexible, and the internal space height must be limited., the height of electronic components located in the product has become one of the important considerations for designing coil sets. For example, the patent of The Republic of China Patent No. I268520 is a transformer comprising a plurality of winding seats and a plurality of cores coupled to the plurality of winding seats. Each of the winding seats includes a primary coil region, a primary coil region and a consistent hole, And the plural of winding seats are combined to define an accommodation space. The transformer has a horizontal design that greatly reduces the height required for installation. However, when it is installed in an electronic product,The coil area and the circuit components in the electronic product are not shielded, and electromagnetic interference (EMI) is easily generated. The simplest way in the prior art is to use an insulating tape to wrap around the coil area, reducing the chance of electromagnetic Wave interference between the coil area and the electronic product, but the barrier effect of the method is limited, and the insulating tape itself is relatively fragile and It is easy to break during transportation or assembly, and it is easy to generate electromagnetic wave interference.But the barrier effect of this method is limited, and the insulating tape itself is relatively fragile and It is easy to break during transportation or assembly, and it is easy to generate electromagnetic wave interference.But the barrier effect of this method is limited, and the insulating tape itself is relatively fragile and It is easy to break during transportation or assembly, and it is easy to generate electromagnetic wave interference.

Further, the width of the outlet notch is larger than the width of the heat dissipation through hole.

Further, the side outlet portion includes an outlet opening through which the wire is passed.

Further, the side outlet portion includes a placement area for the iron core structure to be placed, and a through opening for communicating the placement area and for the bottom wall to pass through.
