Abstract
A deflection yoke comprises a magnetically permeable core having two separable halves. A yoke interlock member is attached to each core half with its position accurately fixed with respect to the core a pair of vertical deflection coils are toroidally-wound about the core with their position fixed with respect to the interlock members. The interlock member incorporates a number of horizontal coil engaging surface to fix the position of a horizontal coil with respect to the interlock member. The interlock member also incorporates tabs which separate the horizontal coils by a known distance. A pair of saddle-type horizontal deflection coils are disposed within the interior region of the core engaging the coil engaging surfaces and separated by the coil separation tabs. The interlock member therefore allows the construction of a yoke which provides accurate positioning of the vertical and horizontal coils with respect to each other and with respect to the core.
