ABSTRACT:
An integrally molded coil assembly extends about the intermediate leg, and is wedged between the outer legs of an E-frame magnet. It has rigid interior walls and top and bottom flange portions. Flexible flange extensions extend from the sides of the flange portions. The extensions are coplanar with the flange portions during the coil winding operations, and are bent in overlapping relationship during assembly of the coil form on the magnet. The flange portions are dimensioned so that the extensions are tightly wedged against the outer legs.
