Description of the invention: [Technical field to which the invention belongs] The present invention relates to a south-voltage transformer mounted on a circuit board of various electronic devices, and more particularly to a high-voltage transformer with an insulating winding frame, the insulating winding The frame is stacked in a direction substantially perpendicular to the circuit board, and is formed by a cylindrical second winding shaft portion for winding the i-side winding and a cylindrical second winding shaft portion for winding the secondary-side winding ^ [Prior technology] # For the high voltage transformers of this kind, there are known-a variety of liquids for use in notebook computers (enemy bQGkeGmpute〇, etc.): said; display-panel backlight; The cathode discharge f (cold cathode, hereinafter referred to as CCFL) is simultaneously discharged, and the inverter transformer used in the dc / ac converter (i ,, eltel for children) is discharged at the same time. (Inverter Transformer). In the above-mentioned inverter transformer, since the 12V left 坚 added to the primary winding twice and the target Φ around the known target Φ is fixed and converted = 2 "into The method of output to the soil I and M and the primary side winding and 2 times The side knot & & mouth this month will cause a corona discharge between the 1% and 1% groups of people. In order to prevent the aforementioned situation, the use of;-(: 2 1 spools and 2 spools There are 5 types of insulating winding frames between the parts, but the shape of the partition part between the winding part _ Youban Fuyu in the brother 1 winding shaft part and the second heart door hunting part of the plate It is true that there is a problem that there is a possibility of Zhaiqian, bar margin pressure resistance, mountain charge)) across the next part. Electricity (creeping 316758 5 200534301) It is expected that, in order to solve the aforementioned problem, a technical content of an inverter to change the voice is proposed, which is between the first! Winding shaft portion and the second winding shaft portion: The winding frame of the virtual winding groove of the winding material, thereby improving the insulation withstand voltage between the primary winding and the secondary winding, and preventing: corona: electric hair (see the following patent document υ. In addition, A technique is also known in which the diameter of the outer peripheral surface of the first stern shaft portion is formed so that the entire width across the axial direction is greater than the diameter of the outer peripheral surface of the second winding shaft portion. The side C is generally located on the inner side of the winding diameter) = 2 ^ • The insulation withstand voltage between the windings prevents the occurrence of creeping discharges. [Patent Document 1] Japanese Patent Laid-Open No. 200 (M24043 [Summary of the Invention] (Problems to be Solved by the Invention) However, in the technique shown in the above Patent Document 1, the height of the winding frame (length in the axial direction) is significantly increased because the virtual winding groove is provided as described above. It is difficult to make the winding frame and high voltage transformer thin (Low Profile). In addition, when the diameter of the outer peripheral surface of the first winding shaft portion is greater than the diameter of the outer peripheral surface of the second winding shaft portion in the axial direction, 1 The winding area of the secondary winding is then shifted to the outer peripheral side of the i-th winding shaft 4, so it is unavoidable to increase the winding diameter of the i-side winding, which will cause the problem of large-sized winding frame. The invention was developed by the developer in view of the above problems, and its purpose is to provide a method to prevent the occurrence of corona discharges between 1—4 windings and 2nd-side windings (u〇r_ dlscharge), and to simplify the winding frame. And thin 316758 6 200534301 type (L0wProfne) high dust changing magic device. (Means to solve the problem): ^ 成: j ^ Objective'The high voltage transformer of the present invention is as follows: Invention of the high-side winding cylindrical tube! Γ has a second winding surface Qiu: * section and a cylindrical 夬 for winding the secondary winding: r; Insulation winding frame formed by lamination is tender = part of the above ... 1 end of the winding shaft part side, and your Haidi 2 windings The second winding shaft portion of the shaft portion is smaller than the distance from the & 1 winding shaft portion to the above-mentioned end portion. The diameter of the winding portion is smaller than that of the closer side, and the first winding shaft portion is configured as The diameter is increased by the distance from the front, the axis of the winding shaft of f spear 2 and k is gradually increased by the distance from the near side of the rear center of the second knot mentioned above, and the diameter of the side farther from the distance of L It is the same, and it is 1 乂 near the side to the predetermined position (effect of the invention) The pre-reading starts to increase gradually. The high-voltage transformer in the box like this one! In this manner, the end portion on the side of the second winding shaft portion is such that both the W of the end portion on the side of the first winding shaft portion and the partition wall portion are between 2, =, and 'the surface axis right side. Therefore, the virtual winding groove proposed in the i-th winding shaft portion and the conventional technology, that is, charge = 'It is not necessary to set the insulation between the high-voltage side of the group and the 1: under-side winding: ": The secondary winding can reduce the thickness of the winding frame 316758 7 ^ 00534301 f to achieve a thinner σ, and it can be produced between the secondary winding and the secondary winding. (Coronadisch metaphor). The end of the side is configured to have a larger diameter than the distal end of the second winding shaft portion, so the diameter of the side closer to the sleeve portion of the winding wheel portion becomes larger than the second diameter. ^ / The winding area of the side winding can be suppressed by the entire width in the axial direction, and the winding diameter of the primary side winding can be suppressed. Therefore, [Embodiment] can simplify the structure of the winding frame. Refer to the figure below. The figure shows the exploded oblique view of the schematic structure of the implementation of the second high-f transformer of the present invention. In addition, the coordinate axis of the * direction of the resentment house transformer is in the following two = :: : The broad direction is called forward, the negative direction is called back, = is called right, and the negative direction is called the left y-axis square. The negative direction is called the downward direction. The positive direction of the axial direction is called the upward direction.
