Abstract

PURPOSE:To heighten corona starting voltage, by dividing a rectangular-section bobbin, which constains an annular steel core and on which a low-voltage coil is wound, into two sections by cutting it in radial surface, and winding a high-voltage coil on the outside of this bobbin and integrating them together by mold resin into one body. CONSTITUTION:A bobbin 8 is composed of two separate bobbins 8A and 8B, and the bobbins 8A and 8B take a shape of U-section annular body consisting of an outside wall 9a, an inside wall 9b and a bottom wall 9c, and a rectangular-section annular bobbin is formed when these bobbins are placed in positions of facing each other. And the bobbins 8A and 8B are provided with projections 10a and 10b on their outside wall 9a and bottom wall 9c, respectively, so that a constant gap is left between the walls when a low-voltage coil 2 is wound. Further, the outside wall 9a is provided with plural notches 12, the bottom wall 9c is provided with plural through holes, the inside wall 9b is made lower than the outside wall 9a, and a gap A is opened between the bobbins 8A and 8B. Finally, a molding resin 5 is poured to form them into one body.
