(イ) 産業上の利用分野
本考案はテレビジヨン受像機等に使用されるフ
ライバツクトランスに関する。[Detailed description of the invention] (a) Industrial application field The present invention relates to a flyback transformer used in television receivers and the like.
(ロ) 従来技術
所謂分割巻きフライバツクトランスは、コイル

線が巻装されない非巻線溝に配される。(B) Prior Art A so-called split-winding flyback transformer has a structure in which a voltage winding is wound in multiple winding parts on a coil bobbin in separate windings, and a rectifier diode is connected between each winding part. The rectifier diode is arranged in a non-winding groove where no winding is wound.
前記整流ダイオードと前記巻線部とを接続する

流ダイオードのリード線に巻線を巻き付けて半田
付けするようにしていた。 Conventionally, in order to connect the rectifier diode and the winding part, a metal terminal is planted in the non-winding groove of the coil bobbin, and the lead wire and the winding of the diode are soldered to this terminal, or the rectifier is connected to the rectifier diode and the winding part. The diode is supported within the non-winding groove by a suitable holding means, and the winding is wound around the lead wire of the rectifier diode and soldered.
しかしながら、金属端子を用いる場合、電圧が
かかる部分が大きくなり、絶縁に要する空間を多
く必要とするばかりでなく、端子を保持する部分
に絶縁樹脂が十分施されないとコロナ放電が発生
しやすくなる。 However, when using metal terminals, the area to which the voltage is applied becomes large, requiring a large amount of space for insulation, and corona discharge is likely to occur if the insulating resin is not applied sufficiently to the area that holds the terminal.
また、整流ダイオードのリード線は１mm以下の
細いものであるために、前記リード線に巻線を巻

0.1mm以下の太さであるので、これを巻き付けよ
うとした場合、上巻線に加わる張力によつて断線
不良を生じるという欠点があつた。 In addition, since the lead wire of a rectifier diode is thin, less than 1 mm, if a winding is wound around the lead wire, the lead wire will wobble, causing corona discharge or dielectric breakdown if it comes close to parts with different potentials. There is a risk. Furthermore, the windings that form the high voltage windings
Since the thickness is less than 0.1 mm, when attempting to wind the wire, the tension applied to the upper winding would cause the wire to break.
