Description
【考案の詳細な説明】 本考案は変成器の絶縁スペーサに関するものである。[Detailed explanation of the idea] The present invention relates to an insulating spacer for a transformer.
従来、コイルボビンの中央部に■形鉄心を嵌挿するとと
もに、上記コイルボビンの両側部にＯ形鉄心を嵌着し、
この両側のＯ形鉄心でもって中央の■形鉄心を挟着接合
するようにした変成器がある。Conventionally, a ■-shaped iron core was inserted into the center of the coil bobbin, and an O-shaped iron core was fitted into both sides of the coil bobbin.
There is a transformer in which the O-shaped cores on both sides are sandwiched and joined to the center ■-shaped core.
このような変成器では、前記コイルボビンに巻着された
コイルの外周面とＯ形鉄心の内周面との間に適度の間隙
を設けることが困難であって、コイルとＯ形鉄心との間
の沿面距離を確保することが容易でなかった。In such a transformer, it is difficult to provide an appropriate gap between the outer circumferential surface of the coil wound around the coil bobbin and the inner circumferential surface of the O-shaped core. It was not easy to secure creepage distance.
従来は、Ｏ形鉄心を大きくしてコイルとの間隙を広げる
か、またはコイルの外周に巻着する絶縁テープの巻厚を
厚くするなどして、上記沿面距離を確保したり絶縁性を
高めるようにしているが、このようにすると大形化した
り、絶縁テープの巻付作業に必要以上の負担がかかり、
好ましくなかった。Conventionally, attempts were made to secure the above creepage distance and improve insulation by increasing the size of the O-shaped core to widen the gap between the coil and the coil, or by increasing the thickness of the insulating tape wrapped around the outer circumference of the coil. However, doing this would result in an increase in size and an unnecessarily burdensome work on wrapping the insulating tape.
I didn't like it.
本考案はこのような点を改良しようとするもので、変成
器を作製するにあたって、コイルと鉄心との間の沿面距
離を確保できるとともに、その絶縁処理作業が極めて容
易にでき、さらには成形容易であるとともにその成形に
要する費用が軽減できる絶縁スペーサを提供しようとす
るものである。The present invention aims to improve these points, and when manufacturing a transformer, it is possible to secure the creepage distance between the coil and the iron core, and the insulation treatment work is extremely easy, and furthermore, it is easy to mold. It is an object of the present invention to provide an insulating spacer which can reduce the cost required for molding the spacer.
本考案の一実施例を図面に基づいて説明する。An embodiment of the present invention will be described based on the drawings.
Ａは本考案に係る絶縁スペーサで、この絶縁スペーサＡ
は、円弧状の接続部１でもって対向する一辺を接続され
て相互に開成をなす両側の凹部２と、この両側の四部２
の開口縁のフランジ部３とをやや可撓性の合成樹脂によ
って一体に射出成形するとともに、上記接続部１および
両側のフランジ部３の中央部を打抜くか切欠いて嵌挿穴
５および切欠部６をそれぞれ設けたものである。A is an insulating spacer according to the present invention, and this insulating spacer A
consists of recesses 2 on both sides whose opposing sides are connected by an arc-shaped connecting part 1 and open to each other, and four parts 2 on both sides.
The flange part 3 on the edge of the opening is integrally injection molded with a slightly flexible synthetic resin, and the center part of the connecting part 1 and the flange parts 3 on both sides are punched out or notched to form the insertion hole 5 and the notch part. 6 respectively.
そうして、上記絶縁スペーサＡの開成面にコイルボビン
１０を配置し、前記両側の凹部２を開成から平行状に閉
じてその凹部２をコイルボビン１０の両側部にそれぞれ
被嵌する。Then, the coil bobbin 10 is placed on the open surface of the insulating spacer A, and the recesses 2 on both sides are opened and closed in a parallel manner, and the recesses 2 are fitted onto both sides of the coil bobbin 10, respectively.
この際円弧状に成形された前記接続部１は逆方向に折曲
されて直線状になる。At this time, the arcuate connecting portion 1 is bent in the opposite direction to become a straight line.
このようにしてコイル１１が巻着された上方および下方
のコイルボビン１０にそれぞれ絶縁スペーサＡが嵌装さ
れる。Insulating spacers A are fitted onto the upper and lower coil bobbins 10, respectively, around which the coil 11 is wound in this manner.
また上記上下の絶縁スペーサＡをその接続部１において
合わせ、その内部のコイルボビン１０の中央部に、短冊
状の磁性鋼板を積層して形成した■形鉄心１２を嵌挿し
、また両側の凹部２の外周に、薄板からなる磁性鋼帯を
連続的かつ口字形状に巻回積層して形成したＯ形鉄心１
４を嵌着し、このとき二の両側のＯ形鉄心１４の対向す
る内側面を前記フランジ部３に当接し、Ｏ形鉄心１４の
外側面と絶縁スペーサＡの四部２の外側面とが面一にな
るようにし、さらに前記■形鉄心１２の上端および下端
部において両側のＯ形鉄心１４にコ字状金具１６を嵌着
し、このコ字状金具１６でもってＩ形鉄心１２の抜止め
をするとともに、両側のＯ形鉄心１４と中央の■形鉄心
１２とを前記切欠部６を介してしつかり接合するように
する。Further, the above-mentioned upper and lower insulating spacers A are brought together at their connection parts 1, and a square iron core 12 formed by laminating strip-shaped magnetic steel plates is inserted into the center of the coil bobbin 10 therein, and a O-type iron core 1 formed by continuously winding and laminating magnetic steel strips made of thin plates in a mouth shape around the outer periphery.
At this time, the opposing inner surfaces of the O-shaped cores 14 on both sides of the insulating spacer A are brought into contact with the flange portion 3, and the outer surfaces of the O-shaped cores 14 and the outer surfaces of the four parts 2 of the insulating spacer A are flush with each other. Furthermore, U-shaped metal fittings 16 are fitted to the O-shaped iron cores 14 on both sides at the upper and lower ends of the ■-shaped iron core 12, and the U-shaped metal fittings 16 prevent the I-shaped iron core 12 from slipping out. At the same time, the O-shaped cores 14 on both sides and the square-shaped core 12 in the center are firmly joined through the notch 6.
なお１７はリード線の引出用凹溝で゛ある。Note that 17 is a groove for drawing out the lead wire.
また、前記絶縁スペーサＡの凹部２とフランジ部３とに
よってコイル１１とＯ形鉄心１４との間の最短の沿面距
離ｌが充分にとれるとともに、接続部１によって上下の
コイル１１間の沿面距離も充分にとることができる。In addition, the recess 2 and flange 3 of the insulating spacer A allow a sufficient minimum creepage distance l between the coil 11 and the O-shaped core 14, and the connection 1 also reduces the creepage distance between the upper and lower coils 11. You can take enough.
なお、実施例においては２つのコイルボビン１０のそれ
ぞれに耐圧スペーサＡを被嵌した場合について図示した
が、この耐圧スペーサＡはコイル１１とＯ形鉄心１４と
の間に所定の沿面距離を要求される一方のコイルボビン
１０にのみ被嵌するようにしてもよい。In the embodiment, a case is shown in which a pressure-resistant spacer A is fitted to each of the two coil bobbins 10, but this pressure-resistant spacer A is required to have a predetermined creepage distance between the coil 11 and the O-shaped core 14. It may be made to fit into only one coil bobbin 10.
本考案によれば、コイルボビンに被嵌された凹部とこの
凹部の開口縁のフランジ部とによって、コイルとＯ形鉄
心との間の必要な沿面距離が確保でき、また上記凹部を
コイルボビンに被嵌するとともにこの凹部の外周にＯ形
鉄心を嵌着すればよいから、絶縁テープをコイルの外周
に巻付けるものに比べ、その絶縁処理作業が極めて容易
にできる。According to the present invention, the necessary creepage distance between the coil and the O-shaped core can be secured by the recess into which the coil bobbin is fitted and the flange at the opening edge of the recess, and the recess into which the coil bobbin is fitted can ensure the required creepage distance between the coil and the O-shaped core. At the same time, since it is sufficient to fit the O-shaped iron core around the outer periphery of the recessed portion, the insulation treatment work can be performed much more easily than when an insulating tape is wound around the outer periphery of the coil.
また円弧状の接続部でもって凹部の対向する一辺を開成
に接続するようにしたから、絶縁スペーサの一体射出成
形が容易に行なえるとともに、凹部をコイルボビンに被
嵌したとき上記接続部を直線状にすることができ、絶縁
スペーサ間に間隙を生じさせることなく上下の絶縁スペ
ーサを密着させることができる。In addition, since the opposite sides of the recess are connected in an open manner using an arc-shaped connection part, integral injection molding of the insulating spacer can be easily performed, and when the recess is fitted onto the coil bobbin, the connection part can be formed in a straight line. The upper and lower insulating spacers can be brought into close contact with each other without creating a gap between the insulating spacers.
また絶縁スペーサを一体成形し、部品数を少なくしたの
で、その成形に要する費用が軽減で゛きる。Furthermore, since the insulating spacer is integrally molded to reduce the number of parts, the cost required for molding can be reduced.
