Abstract

PURPOSE:To obtain the resin mold apparatus excellent in dielectric strength by a method wherein a lead wire of each winding is drawn upward and integratedly molded by the resin together with the winding in such a manner of surrounding the rising part of the lead wire to form a winding unit. CONSTITUTION:A low voltage winding 10 is wound on an insulating bobbin 9 as large as cut cores 1A, 1B can be inserted, and the lead wire 10L is drawn upward. Then, a high voltage winding 12 is wound on an insulating bobbin 11 having an inner diameter larger than the outer diameter of the wound-up low voltage winding 10 and likewise, the lead wire 12L being drawn upward and the low and high voltage windings 11, 12 being concentrically arranged to be installed in a mold type. In this condition, molding resin is injected, the rising parts of the respective lead wires 10L, 12L also being molded at the same time and a projecting part 13A is formed integratedly with a resin molded layer 13 to be made the winding unit. The projecting part is housed in a magnetic shield frame body 14 in such that a prescribed gap is kept. Thereby, the resin molding device excellent in the dielectric strength can be obtained.
