High voltage transformer for deflection of electron beams
First Claim
1. A transformer for generating a high voltage for control of an electron beam comprising a second winding body comprising a secondary winding for providing a high voltage;
- a case surrounding the second winding and having a second opening in an end wall located at a plane disposed parallel to the axis of the secondary winding for allowing the insertion of the second winding body into the case through the second opening;
an electrical connection for the second winding body and running through said second opening;
a first winding body comprising a primary winding disposed concentrically to the second winding body; and
means on the edge of said second winding body providing a seal for the liquid plastic resin during filling of the case and preventing the resin from extending to the first winding body such that the first winding body can be exchanged or inserted into the second winding body;
a cast of synthetic resin disposed in the case and surrounding the second winding body.

Abstract
A high voltage transformer is provided for the voltage employed in the line deflection of an electron beam in a television receiver. The secondary high voltage winding is inserted into a case via an opening running parallel to the axis of the primary and secondary winding and is disposed in the case separate from the primary winding and is surrounded by a cast plastic resin. Preferably, the secondary winding body snaps into elastically supported protrusions disposed at the case. The plastic resin is filled into position through said opening. The high voltage connection is immersed into the plastic resin and is then led outwardly.
