ABSTRACT:
The invention is directed to a formed metal blocking, for mounting within wedge-shaped gaps between coils of a toroidal transformer, including butterfly-shaped top and bottom core blockings. The blockings are formed from identical stampings, each stamping having a pair of U-shaped coil-engaging faces joined along their inner legs by a center web. The stampings are joined back to back and have a number of flanges which are bent over for securing the stampings to one another. The stampings have an apertured tab at the end of the center web used to form a lifting eye for the top blocking. With the bottom blocking the tabs are folded over for mounting to a base plate. The outer legs of the U-shaped faces are longer than the inner legs and center web to create a gap in the electric path surrounding the core.
