Description
本考案は変圧器の構造改良に関し、特に、二次側の沿面距離を伸ばすことによって金属線を巻設しやすく、金属線を隔板の溝部内に巻設することによって、二次側の隣合う巻線部において電位差が発生して過電圧となり、変圧器が焼けるのを防止できる変圧器に関する。 The present invention relates to the improvement of the structure of a transformer, and in particular, it is easy to wind a metal wire by increasing the creepage distance on the secondary side, and it is next to the secondary side by winding the metal wire in the groove of the partition plate. The present invention relates to a transformer capable of preventing a transformer from being burnt by generating a potential difference in a matching winding portion and causing an overvoltage.
ハイテク時代に入り、長期に渡って使用されていたブラウン管ディスプレイは徐々にＴＦＴ液晶ディスプレイ（ＴＦＴ ＬＣＤ）およびプラズマディスプレイ（ＰＤＰ）などの平面ディスプレイ（ＦＰＤ）に取って代わられている。ＴＦＴ液晶ディスプレイには高効率で小型のランプによるバックライトシステムが必要であり、一般に液晶パネル（ＬＣＤ）に最もよく使用されているのは冷陰極管（Cold Cathode Fluorescent Lamp：ＣＣＦＬ）をパネルのバックライトとしたものである。冷陰極管はインバータ回路によって駆動されるが、高電圧出力を行うために通常高周波変圧器が使用される。しかし、液晶パネルのサイズは益々大きくなっているので、冷陰極管の長さおよび数量を増加させる必要があり、それに伴って変圧器が駆動しなければならない電圧も高くなる。 Entering the high-tech era, CRT displays that have been used for a long time are gradually being replaced by flat panel displays (FPD) such as TFT liquid crystal displays (TFT LCD) and plasma displays (PDP). TFT liquid crystal displays require a backlight system with high efficiency and a small lamp. In general, the most commonly used liquid crystal panel (LCD) is a cold cathode fluorescent lamp (CCFL). It is a light. Although the cold cathode tube is driven by an inverter circuit, a high-frequency transformer is usually used for high voltage output. However, as the size of the liquid crystal panel becomes larger and larger, it is necessary to increase the length and quantity of the cold-cathode tubes, and accordingly, the voltage that the transformer has to drive increases.
図７、８に示す従来技術による高周波変圧器は、ボビン（Bobbin）ＡおよびコアセットＢから構成され、ボビンＡ上には一次側コイルＡ１および二次側コイルＡ２が形成され、二次側コイルＡ２には複数の隔板Ａ２１が設けられ、隔板Ａ２１の個数は使用電圧の高低に基づいて決定される。高周波変圧器の理想的な負荷における使用状態において、冷陰極管Ｃ、Ｄが属する負の温度の等価インピーダンスの特性負荷を通し、さらに導通後に電流を上昇させ、インピーダンスを低下させ、さらに製造コストも考慮するために、一つの変圧器によって対応する並列の冷陰極管Ｃ、Ｄを運転させるが、冷陰極管Ｃ、Ｄ間のインピーダンスはそれぞれ異なるので、冷陰極管Ｃ、Ｄの管端部に分流（Ｉ１、Ｉ２）が起こり、冷陰極管Ｃ、Ｄの電流が不均一となり、冷陰極管Ｃ、Ｄの輝度の差が大きくなる。また、従来技術による変圧器は、複数の冷陰極管Ｃ、Ｄを運転させるとき、使用される電流が冷陰極管Ｃ、Ｄの使用個数に伴って倍数的に増加するので、高周波変圧器の二次側コイルＡ２に使用されるコイル線が太くなり、二次側コイルＡ２の巻き線空間が不足し、コイルを大きくして大型の変圧器にする必要がある。しかし、大型の変圧器にすることによって、コストが増加する。 7 and 8 includes a bobbin A and a core set B. A primary coil A1 and a secondary coil A2 are formed on the bobbin A, and a secondary coil is formed. A2 is provided with a plurality of partition plates A21, and the number of partition plates A21 is determined based on the level of operating voltage. In the use state of the ideal load of the high-frequency transformer, it passes through the characteristic load of the negative impedance equivalent impedance to which the cold-cathode tubes C and D belong, further increases the current after conduction, lowers the impedance, and further reduces the manufacturing cost For consideration, the corresponding cold cathode tubes C and D are operated by a single transformer, but the impedances between the cold cathode tubes C and D are different from each other. Splitting (I1, I2) occurs, currents in the cold cathode tubes C, D become non-uniform, and a difference in luminance between the cold cathode tubes C, D increases. Further, in the transformer according to the prior art, when a plurality of cold cathode tubes C and D are operated, the current used increases multiplely with the number of cold cathode tubes C and D used. The coil wire used for the secondary side coil A2 becomes thick, the winding space of the secondary side coil A2 becomes insufficient, and it is necessary to enlarge the coil to make a large transformer. However, the cost increases by using a large transformer.

１．従来技術による変圧器のボビンＡの二次側コイルＡ２に金属線を巻設するとき、金属線は隔板Ａ２１を跨ぐ必要があり、二次側コイルＡ２の巻線部に分担された電圧が負荷を超えたとき、金属線が隔板Ａ２１を跨ぐ部分に電位差が発生し、充電および放電による電弧が形成され、火花が発生して変圧器が焼けてしまう。
２．二次側コイルＡ２において、仮に金属線が隔板Ａ２１上を跨いでいる場合、二次側コイルＡ２に容易に電位差が発生し、変圧器全体の耐圧性に影響を及ぼし、変圧器の使用寿命を短くする。
1. When winding a metal wire around the secondary coil A2 of the bobbin A of the transformer according to the prior art, the metal wire needs to straddle the partition plate A21, and the voltage shared by the winding portion of the secondary coil A2 is When the load is exceeded, a potential difference occurs in the portion where the metal wire crosses the partition plate A21, an electric arc is formed by charging and discharging, a spark is generated, and the transformer is burned.
