Abstract
A blind hole pot core transformer comprised of a base member having a toroidal channel with a central post and a cover member also having a toroidal channel with a central post. A bobbin winding is positioned within a cavity defined by the toroidal channels of the base and cover members with a core comprised of the central posts of the base and cover member positioned within an opening in the bobbin winding. A compressible alignment member is positioned within an opening formed on outer mating surfaces of the central posts of both the base and cover members to retain the base and cover members in a desired orientation with respect to each other. The compressible alignment member has a cross-sectional area that is greater than the openings in the base and cover members so that any gap between the alignment member and the inner walls of at least one of the openings is eliminated thereby facilitating alignment between the central posts comprising the core of the device.
