【考案の詳細な説明】
本考案は、特に高周波帯でしかも高周波誘導加
熱器に適用して好適な高周波トランスの巻線型状
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding shape of a high-frequency transformer suitable for application to a high-frequency induction heater, particularly in a high-frequency band.
第１図は一般的なトランスの回路を示すもので

次コイルには、大電流が流れるようになる。 Figure 1 shows a general transformer circuit, and the secondary side includes capacitor C1 and work coil.
It becomes a series resonant circuit of L 1 , and as is well known, the output load impedance becomes zero at the resonant frequency, and the current flows infinitely. Of course, a resistance R actually exists. Therefore, a large current flows through the secondary coil of this transformer.
ところで、従来は、一次及び二次のボビンが
夫々必要になつており、これに起因して絶対的な
スペースが大きくなつてしまう欠点を有してい
る。 By the way, the conventional method requires a primary bobbin and a secondary bobbin, which has the drawback of increasing the absolute space.

る。 In view of this point, the main purpose of the present invention is to propose a compact transformer.
以下本考案の一実施例について図面を参照しな
がら詳細に説明する。 An embodiment of the present invention will be described in detail below with reference to the drawings.

す。 FIG. 2 is a schematic perspective view showing an example of the present invention, in which a bobbin is also used. The number of turns of the secondary winding is the same as in the example shown in FIG. The secondary winding 10 also serves as a primary bobbin. 11 indicates the lead of the secondary winding. And the secondary winding 10
A wire 13 is wound around the circumference as a primary winding. Therefore, the primary bobbin is also used as the secondary winding, and the space (occupancy) for the winding is reduced, in other words, the core can be made smaller. This reduces the overall size of the transformer. 16 indicates an E-type ferrite core.

い。 FIG. 3 is a diagram showing another example of the present invention, and the second
An example of a water cooling device for the secondary winding shown in the figure is shown. Two copper pipes 15 are connected to both ends of the secondary winding 10.
It is wound and brazed or soldered to the secondary coil (primary bobbin). Furthermore, the primary winding will be wound on this, but since the copper pipe 15 is parallel to the winding frame 10 when winding the wire 13, it will not get in the way, and the number of turns of the primary coil will not be reduced.

縁帯を介して一次巻線を巻回できることになり、
一次巻線の容積が小さく設定し得る効果を有す
る。 As described above, according to the present invention, the bobbin of the primary winding of a high-frequency transformer is constructed with a secondary winding made of a plate-shaped conductor wound in one to several turns in alignment with the middle leg of the core. Since the plate-shaped conductor itself that becomes the next winding is highly rigid, the primary winding can be wound through an insulating band without the need for a special bobbin as in the conventional case.
This has the effect that the volume of the primary winding can be set small.
