Abstract:
1. A circuit carrier and transformer assembly, comprising: a transformer comprising a bobbin with multiple bobbin bases, wherein said bobbin has a winding section comprising a first winding part and a second winding part, wherein a primary winding coil and a secondary winding coil are wound around the first winding part and a second winding part, respectively, wherein a first side plate and a second side plate are arranged on opposite sides of said first winding part, and a third side plate and a fourth side plate are arranged on opposite sides of the second winding part, wherein said second side plate of said first winding part is separated from said third side plate of said second winding part by a gap; and a circuit carrier comprising multiple receiving holes corresponding to respective bobbin bases of the bobbin, wherein said bobbin bases are received in respective receiving holes when said transformer is mounted on said circuit carrier, wherein said circuit carrier further has a slot corresponding to the range of from said second side plate of said first winding part to said third side plate of said second winding part, thereby maintaining a creepage distance between said primary winding coil and said secondary winding coil when said transformer is mounted on said circuit carrier.
