Description
【0001】[0001]
本考案は、主としてトランスやチョークに用いられる平面コイルに関するもの である。 The present invention mainly relates to a plane coil used for a transformer or a choke.
【0002】[0002]
従来の平面コイルを用いた薄型トランスの分解斜視図を図3に示す。この従来 例の平面コイルの平面図を図2に示す。平面コイル11は、絶縁体12上に、渦 巻状の導体13が形成されたものであり、15はコアが挿入される孔である。こ の平面コイル11を所要数積み重ね、一対のフェライトコア14ではさみ、薄型 トランスを構成している。 この平面コイルとしては、片面又は両面プリントコイル、銅板打抜きコイル等 種々の構成があり、ターン数も適宜設定される。又、この平面コイルでは、導体 幅は、内側から外側まで同じ幅で構成されていた。 FIG. 3 shows an exploded perspective view of a conventional thin transformer using a planar coil. A plan view of the conventional planar coil is shown in FIG. The planar coil 11 is formed by forming a spiral conductor 13 on an insulator 12, and 15 is a hole into which a core is inserted. A required number of flat coils 11 are stacked and sandwiched by a pair of ferrite cores 14 to form a thin transformer. As this plane coil, there are various structures such as a single-sided or double-sided printed coil, a copper plate punched coil, and the number of turns is appropriately set. Also, in this planar coil, the conductor width was the same from the inside to the outside.

この従来の平面コイルでは、内側部分での発熱が大きく、温度上昇が大きかっ た。この平面コイルでは、その最高温度上昇部位が問題となるため、この内側部 分での発熱がその使用上の制約となっていた。 この温度上昇の制御としては、導体断面積を大きくすることにより発熱を低減 できるが、導体断面積を大きくすると、平面コイルが大型化するといった問題点 があった。 本考案は、上記の事を鑑みて、大型化することなく、温度上昇を小さくできる 平面コイルを提供することを目的とする。 In this conventional planar coil, the heat generated in the inner part was large and the temperature rise was large. In this planar coil, the part where the maximum temperature rises becomes a problem, so the heat generation in this inner part was a constraint on its use. To control this temperature rise, heat generation can be reduced by increasing the conductor cross-sectional area, but there is a problem that the plane coil becomes larger when the conductor cross-sectional area is increased. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a planar coil capable of reducing the temperature rise without increasing the size.
【0004】[0004]
本考案は、絶縁板上に渦巻状に導体を配設してなる平面コイルにおいて、前記 渦巻状導体の内側の導体の幅を外側の導体の幅よりも太くしたものである。 本考案において、内側の導体幅を太くし、導体断面積を大きくしたので、発熱 しやすい内側での温度上昇を小さくすることができた。 According to the present invention, in a planar coil in which conductors are arranged spirally on an insulating plate, the width of the inner conductor of the spiral conductor is made larger than the width of the outer conductor. In the present invention, the inner conductor width is increased and the conductor cross-sectional area is increased, so that it is possible to reduce the temperature rise on the inner side where heat is easily generated.
【0005】[0005]
本考案に係る一実施例の平面図を図1に示す。この実施例では、内側の導体1 、外側の導体2その中間の導体3の幅をそれぞれ変更し、外側の導体2よりも中 間の導体3を太くし、その中間の導体3よりも内側の導体1を太くした。これに より、従来の平面コイルに比較し、5%温度上昇を下げることができた。また、 この実施例の平面コイルの外寸は、従来と同じに仕上げている。 A plan view of an embodiment according to the present invention is shown in FIG. In this embodiment, the widths of the inner conductor 1, the outer conductor 2 and the conductor 3 in the middle thereof are changed so that the conductor 3 in the middle is thicker than the conductor 2 in the outer side and The conductor 1 is thickened. As a result, the temperature rise could be reduced by 5% as compared with the conventional planar coil. The outer dimensions of the planar coil of this embodiment are the same as the conventional one.

本考案によれば、平面コイルを大型化することなく、温度上昇を下げることが でき、平面コイルの使用範囲を広げることができる。又、平面コイルの使用され るトランス、チョーク等の部品の温度上昇もおさえることができ、部品の使用範 囲の拡大及び信頼性の向上も可能である。 According to the present invention, the temperature rise can be reduced and the range of use of the planar coil can be expanded without increasing the size of the planar coil. In addition, the temperature rise of transformers, chokes, and other components that use planar coils can be suppressed, and the range of components used can be expanded and reliability can be improved.
