<p>PROBLEM TO BE SOLVED: To manufacture a high voltage transformer with high cost performance by arranging a primary winding directly on the outside of a tubular housing, forming two wall type extending parts or protruding parts on the housing and winding the primary winding between these extending parts or protruding parts. SOLUTION: A housing 1 is formed tubularly and a primary winding W1 is arranged directly on the outside thereof. In order to obtained a specified tight primary winding W1, wall type extending parts or protruding parts 2 are formed on the upper and lower sides of the housing 1 and the primary winding W1 is wound between these extending parts or protruding parts 2. Consequently, a high voltage winding WH can be shielded completely when the housing 1 is fixed to a coil winding body 3 during manufacture. Furthermore, an auxiliary winding is arranged above the primary winding W1 and connected with a terminal 10 together with the primary winding W1.</p> |
