US 2011/0254648 A1 · MOVABLE TRANSFORMER EMBEDDED INTO AN OPENING OF A PCB AND A METHOD OF INSTALLING THE SAME

Abstract

A movable transformer embedded into an opening of a PCB includes a first bobbin unit, a second bobbin unit, a third bobbin unit, a winding unit and a magnetic unit. The second bobbin unit is electrically connected to the PCB. The third bobbin unit is electrically connected to the PCB. The winding unit is disposed around the first bobbin unit, the second bobbin unit and the third bobbin unit. The magnetic unit passes through the first bobbin unit and disposed outside the first bobbin unit. In addition, one side of the first bobbin unit is slidably mated with the second bobbin unit, another side of the first bobbin unit is slidably mated with the third bobbin unit, so that the first bobbin unit is selectively moved from one position above the opening to another position in the opening.
