【考案の詳細な説明】
この考案は、トランス、特にストロボ用に適した薄形構
造のＤＣ−ＤＣコンバータ用トランスに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transformer, particularly a DC-DC converter transformer having a thin structure suitable for strobes.
近年、電子部品はますます小形化されてきているが、ト
ランスだけは小形化、薄形化がおくれている。In recent years, electronic components have become increasingly smaller, but transformers have been slow to become smaller and thinner.
特に機器のコンパクト化に伴いトランスの薄形化要求が
強い。In particular, as equipment becomes more compact, there is a strong demand for thinner transformers.
特に、ストロボ用のＤＣ−ＤＣコンバータ用トランスに
ついては一次電流を太きくしなげればならないため、コ
イルをすべてプリント化することができず、小形化への
障害となっていた。In particular, in the case of a transformer for a DC-DC converter for a strobe, the primary current must be made thicker, so it is not possible to print all the coils, which has been an obstacle to miniaturization.
そこで巻線を用いても小形化・が図れるＤＣ−ＤＣコン
バータ用トランスの出現が従来より望まれていた。Therefore, there has been a desire for a transformer for DC-DC converters that can be made smaller even by using windings.
この考案はこのような背景をもとになされたもので、以
下に実施例を図面を参照しながら説明する。This invention was made based on this background, and examples will be described below with reference to the drawings.
図において、１はポットコアの下部分、２は上部分、３
と４は薄形コイルで、同心体に配置されている。In the figure, 1 is the lower part of the pot core, 2 is the upper part, 3
and 4 are thin coils arranged concentrically.
５はプリントコイルで、絶縁物シート６に磁心の貫通孔
Ｔを設け、この孔Ｔを中心としてシート６０片表面にう
ず巻状コイル８を形成する。Reference numeral 5 designates a printed coil, in which a magnetic core through hole T is provided in an insulating sheet 6, and a spiral coil 8 is formed on one surface of the sheet 60 with this hole T as the center.
シート６の一端部にすべてのコイルの引出部となるよう
に端子９ａ〜９ｆを形成する。Terminals 9a to 9f are formed at one end of the sheet 6 so as to serve as a lead-out portion for all the coils.
コイル８の一端はシート６０表側で端子９ｂと印刷によ
って形成した導電膜で接続する。One end of the coil 8 is connected to the terminal 9b on the front side of the sheet 60 by a conductive film formed by printing.
コイル８の他端はスルーホールとシート６の裏側に形成
した導電膜とによって端子９ｃに接続する。The other end of the coil 8 is connected to a terminal 9c through a through hole and a conductive film formed on the back side of the sheet 6.
コイル３と４との巻線端は、第４図のように、端子９ａ
、９ｄ〜９ｆに接続する。The winding ends of coils 3 and 4 are connected to terminals 9a as shown in FIG.
, 9d to 9f.
接続完了後のコイルユニット３，４および５はポットコ
ア１に収容し、そののちポットコアの上部分２を覆せる
。After the connection has been completed, the coil units 3, 4 and 5 can be accommodated in the pot core 1, after which the upper part 2 of the pot core can be covered.
端子９ａ〜９ｆはポットコア１の側部のすき間１０から
露出する。Terminals 9a to 9f are exposed through gaps 10 on the sides of pot core 1.
図示はしないが必要な部分に絶縁処理がしであることは
いうまでもない。Although not shown, it goes without saying that insulation treatment is applied to necessary parts.

コイルのうち一つをプリント巻線化し、残りのコイルは
同心円状のボビンレスコイルにしたので、トランスの厚
みが非常に薄くできる。As is clear from the above embodiment, the strobe DC-DC converter transformer according to this invention is
One of the coils is printed and the remaining coils are concentric bobbinless coils, allowing the transformer to be extremely thin.
また巻線化したボビンレスコイルを用いているので、直
流抵抗弁を少なくして大きな電流がとれることになり、
ストロボ用のトランスの一次側として最適である。In addition, since a wound bobbinless coil is used, a large current can be obtained with fewer DC resistance valves.
Ideal as the primary side of a strobe transformer.
さらに全体をポットコアに収容しており、洩れ磁束を小
さくすることもできる。Furthermore, since the entire device is housed in a pot core, leakage magnetic flux can be reduced.
