ABSTRACT:
A parent-child leadframe type transformer includes a ferrite core module, a child leadframe and a parent leadframe. The parent leadframe has a first opening and a second opening on both ends. The length of the second opening is greater than the length of the first opening along the same axial direction. A containing space is defined between the first and second openings. The child leadframe has a coil winding slot and a through hole for installing the ferrite core module. The axial length of the child leadframe falls between the first and second openings, such that the child leadframe and the ferrite core module can be passed through the second opening, but limited by the first opening. The child leadframe, ferrite core module and parent leadframe are positioned to define a parent-child type transformer structure for reducing the overall height and complying with the safety regulation standards.
