Description

本発明は、一次側コイルのフランジの外面に、板状の二次側コイルを配置した大電流仕様のトランスに関するものである。   The present invention relates to a large-current transformer in which a plate-like secondary coil is disposed on the outer surface of a flange of a primary coil.

車載用の電源トランス等のように、二次側コイルに大電流が流れる高圧トランスにおいては、通常、上記二次側コイルとして、抵抗値を小さくして発熱を抑制するために、銅の帯板を面内方向にリング状に形成した銅板コイルが用いられている。   In a high-voltage transformer in which a large current flows in a secondary coil, such as an in-vehicle power transformer, a copper strip is usually used as the secondary coil to reduce resistance and suppress heat generation. A copper plate coil formed in a ring shape in the in-plane direction is used.

ところで、このような大電流仕様の高圧コイルのうち、銅線をボビンに巻回した一次側コイルに対して出力側として2つの二次側の銅板コイルを用いるものにあっては、例えば下記特許文献1に見られるように、一次側コイルを間に挟むようにして当該一次側コイルの軸線方向の両端側に上記銅板コイルを対向配置する構成が採用されている。   By the way, in such a high-current coil having a large current specification, in which two secondary copper plate coils are used as the output side with respect to the primary coil in which a copper wire is wound around a bobbin, for example, the following patent As can be seen from Document 1, a configuration is adopted in which the copper plate coils are arranged opposite to each other in the axial direction of the primary coil with the primary coil interposed therebetween.

図5〜図7は、本発明者等が先に開発したこの種のトランスを示すものである。
このトランスにおいては、一次側コイル1が巻回されたボビン2の両端フランジ2aの外面に、それぞれ銅板をリング状に形成した二次側コイル3が配置されたもので、二次側コイル3の引き出し部3a、3bが各々一次側コイル1の外周側に屈曲されるとともに、互いの引き出し部3aが共通端子として接続されている。
5 to 7 show this type of transformer developed previously by the present inventors.
In this transformer, secondary coils 3 each having a copper plate formed in a ring shape are arranged on the outer surfaces of both end flanges 2a of the bobbin 2 around which the primary coil 1 is wound. The lead portions 3a and 3b are each bent to the outer peripheral side of the primary coil 1, and the lead portions 3a are connected as a common terminal.

これらボビン2および二次側コイル3は、E型コア6との間の絶縁を確保するために、有底円筒状の絶縁用カバー4内に収納されている。ここで、カバー4の外壁には、引き出し部3a、3bおよび一次側コイル1の引き出し部1aを外方に引き出すための開口部4aおよび溝部4bが形成されている。他方、このカバー4の端部開口は、略円板状の絶縁用キャップ5によって塞がれている。   The bobbin 2 and the secondary coil 3 are accommodated in a bottomed cylindrical insulating cover 4 in order to ensure insulation between the E-type core 6. Here, on the outer wall of the cover 4, an opening 4 a and a groove 4 b are formed for pulling out the lead portions 3 a and 3 b and the lead portion 1 a of the primary coil 1. On the other hand, the end opening of the cover 4 is closed by a substantially disc-shaped insulating cap 5.

そして、これらカバー4およびキャップ5の外周を囲繞するようにして一対のE型コア6が対向配置されている。これらE型コア6は、その背部6aがカバー4の底板およびキャップ5の外面側に配置され、中足6bがカバー4の底板およびキャップ5に形成された孔部からボビン2内に挿入されるとともに、外足6cをカバー4の外周に位置させて配設されている。   A pair of E-shaped cores 6 are arranged to face each other so as to surround the outer periphery of the cover 4 and the cap 5. These E-shaped cores 6 have their back portions 6 a disposed on the outer surface side of the bottom plate of the cover 4 and the cap 5, and the middle legs 6 b are inserted into the bobbin 2 through holes formed in the bottom plate of the cover 4 and the cap 5. At the same time, the outer leg 6 c is disposed on the outer periphery of the cover 4.

ところで、近年、上記構成からなるトランスに対して、これまでよりも大きな電流に対応し得るものが要求されている。このような場合に、一般的には、二次側コイル3の断面積を大きくして電気容量を増す対応する方法が採られている。   By the way, in recent years, a transformer capable of handling a larger current than before is required for the transformer having the above-described configuration. In such a case, generally, a corresponding method is adopted in which the cross-sectional area of the secondary coil 3 is increased to increase the electric capacity.

しかしながら、上記二次側コイル3の断面積を大きくするために厚さ寸法を大きくすると、トランス全体の高さ寸法も大きくなり、低背化の要請に反することになるとともに、特に取付箇所に高さ制限がある場合には適用することができないという問題点を生じる。   However, if the thickness dimension is increased in order to increase the cross-sectional area of the secondary coil 3, the overall height dimension of the transformer also increases. When there is a limit, there is a problem that it cannot be applied.

そこで、二次側コイル3の幅寸法を大きくして断面積を増やそうとすると、図8に示すように、従来よりも二次側コイル3の外径寸法が大きくなり、この結果、実装面積が増大して省スペース化に逆行するという問題点を生じる。   Therefore, when the width dimension of the secondary coil 3 is increased to increase the cross-sectional area, the outer diameter dimension of the secondary coil 3 becomes larger than the conventional one as shown in FIG. The problem is that this increases and goes against space saving.

特開2008−270347号公報JP 2008-270347 A

本発明は、上記事情に鑑みてなされたものであり、僅かな実装面積の増加により、二次側コイルの断面積を増大させて一層の大電流化に対応することが可能になるトランスを提供することを課題とするものである。   The present invention has been made in view of the above circumstances, and provides a transformer that can increase the cross-sectional area of the secondary coil and cope with further increase in current by slightly increasing the mounting area. It is an object to do.

上記課題を解決するため、請求項1に記載の発明は、一次側コイルが巻回されたボビンの少なくとも一方のフランジの外面に、帯板を面内方向にリング状に形成した二次側コイルが配置され、これら一次側コイルおよび二次側コイルを囲繞して磁路を形成するコアが配設されたトランスにおいて、上記二次側コイルの外周に、上記ボビンの軸線方向に屈曲されて上記一次側コイルの外周を囲繞する壁部を形成するとともに、当該壁部と上記一次側コイルの外周との間に絶縁部材を介装したことを特徴とするものである。   In order to solve the above problems, the invention according to claim 1 is a secondary coil in which a strip is formed in a ring shape in the in-plane direction on the outer surface of at least one flange of a bobbin around which the primary coil is wound. Is disposed in the transformer surrounding the primary side coil and the secondary side coil to form a magnetic path, and is bent in the axial direction of the bobbin on the outer periphery of the secondary side coil. A wall portion surrounding the outer periphery of the primary side coil is formed, and an insulating member is interposed between the wall portion and the outer periphery of the primary side coil.

また、請求項2に記載の発明は、請求項1に記載の発明において、上記ボビンの両端のフランジの外面に、それぞれ上記二次側コイルが配置されるとともに、各々の二次側コイルの外周に、上記ボビンの軸線方向に屈曲されて上記一次側コイルの外周を囲繞するとともに先端部同士が対向する壁部を形成したことを特徴とするものである。   According to a second aspect of the present invention, in the first aspect of the present invention, the secondary coils are disposed on the outer surfaces of the flanges at both ends of the bobbin, and the outer periphery of each secondary coil. Further, the wall portion is bent in the axial direction of the bobbin so as to surround the outer periphery of the primary coil and to form a wall portion where the tip portions face each other.

請求項1または2に記載の発明によれば、二次側コイルの外周にボビンの軸線方向に屈曲された壁部を形成しているために、実質的に二次側コイルの幅寸法を大きくして断面積を増大させることができる。   According to the invention described in claim 1 or 2, since the wall portion bent in the axial direction of the bobbin is formed on the outer periphery of the secondary side coil, the width dimension of the secondary side coil is substantially increased. Thus, the cross-sectional area can be increased.

また、一次側コイルの外周を囲繞するように形成された上記壁部と一次側コイルの外周との間に絶縁部材を介装しているために、一次側コイルと二次側コイルとの間の絶縁性も確保することができる。   In addition, since an insulating member is interposed between the wall portion formed so as to surround the outer periphery of the primary side coil and the outer periphery of the primary side coil, it is between the primary side coil and the secondary side coil. Insulating properties can also be ensured.

さらに、実装面積における増加量は、二次側コイルにおける壁部の板厚と絶縁部材の厚さ寸法の分だけであり、しかも上記壁部は、一次側コイルの外周側に屈曲形成されているために、高さ寸法は増加することがない。この結果、僅かな実装面積の増加により、二次側コイルの断面積を大きく増加させて一層の大電流化に対応することが可能になる。   Further, the amount of increase in the mounting area is only the thickness of the wall portion of the secondary coil and the thickness dimension of the insulating member, and the wall portion is bent at the outer peripheral side of the primary coil. Therefore, the height dimension does not increase. As a result, by slightly increasing the mounting area, it is possible to greatly increase the cross-sectional area of the secondary side coil and cope with further increase in current.

図1〜図4は、本発明に係るトランスの一実施形態を示すもので、図5〜図7に示したものと同一構成部分については同一符号を付してその説明を簡略化する。
このトランスにおいては、一次側コイル1が巻回されたボビン2の両端フランジ2aの外面に、それぞれ銅板を面内方向にリング状に形成した二次側コイル10が配置されている。
1 to 4 show an embodiment of a transformer according to the present invention. The same components as those shown in FIGS.
In this transformer, secondary coils 10 each having a copper plate formed in a ring shape in the in-plane direction are arranged on the outer surfaces of both end flanges 2a of the bobbin 2 around which the primary coil 1 is wound.

これら二次側コイル10は、それぞれ従来の二次側コイル3よりも大径のリング状に形成されるとともに、ボビン2の外径寸法よりも僅かに大きな径寸法の位置から外周に至る部分が、プレス加工または絞り加工によって一次側コイル1の外周側に向けて垂直方向に屈曲されている。   Each of these secondary coils 10 is formed in a ring shape having a larger diameter than the conventional secondary coil 3, and a portion extending from the position of the diameter slightly larger than the outer diameter of the bobbin 2 to the outer periphery is formed. They are bent in the vertical direction toward the outer peripheral side of the primary coil 1 by pressing or drawing.

これにより、二次側コイル10の外周には、一次側コイル1の外周を囲繞する壁部11が一体に形成されている。この壁部11は、全体として円筒状に形成されるとともに、一次側コイル1の引き出し部1aおよび二次側コイル10の引き出し部10a、10bを外部に引き出す部分には、それぞれ切り欠き部11aが形成されている。   Thus, a wall 11 surrounding the outer periphery of the primary coil 1 is integrally formed on the outer periphery of the secondary coil 10. The wall portion 11 is formed in a cylindrical shape as a whole, and a notch portion 11a is provided at each portion where the lead portion 1a of the primary side coil 1 and the lead portions 10a and 10b of the secondary side coil 10 are drawn to the outside. Is formed.

さらに、一次側コイル1の外周と二次側コイル10との間には、絶縁部材12が介装されている。この絶縁部材12は、絶縁性樹脂からなる帯板をボビン2の外径よりも幾分小径の筒状に成形したもので、弾性によって開環部を広げてボビン2を挿入した後に復元させることによりボビン2の外周に嵌め込まれている。   Further, an insulating member 12 is interposed between the outer periphery of the primary side coil 1 and the secondary side coil 10. This insulating member 12 is formed by forming a strip made of an insulating resin into a cylindrical shape having a diameter slightly smaller than the outer diameter of the bobbin 2, and is restored after the opening of the ring opening is elastically inserted and the bobbin 2 is inserted. Is inserted into the outer periphery of the bobbin 2.

そして、絶縁部材12が外装された一次側コイル1の両端フランジ2aの外面に、それぞれ二次側コイル10が配置され、互いの壁部11によって絶縁部材12の外周を囲繞するとともに、先端同士を間隔をおいて対向させた状態で、有底円筒状の絶縁用カバー4内に収納されている。   And the secondary side coil 10 is each arrange | positioned on the outer surface of the both-ends flange 2a of the primary side coil 1 by which the insulating member 12 was armored, and while surrounding the outer periphery of the insulating member 12 by the mutual wall part 11, the front-end | tips are mutually connected. It is housed in a bottomed cylindrical insulating cover 4 in a state of being opposed to each other at an interval.

以上の構成からなるトランスにおいては、二次側コイル10の外周にボビン2の軸線方向に垂直に屈曲された壁部11を形成しているために、実質的に二次側コイル10の幅寸法を大きくして断面積を効果的に増大させることができる。   In the transformer having the above configuration, since the wall portion 11 bent perpendicularly to the axial direction of the bobbin 2 is formed on the outer periphery of the secondary coil 10, the width dimension of the secondary coil 10 is substantially reduced. Can be increased to effectively increase the cross-sectional area.

また、一次側コイル1の外周を囲繞するように形成された壁部11と一次側コイル1の外周との間に絶縁部材12を介装しているために、一次側コイル1と二次側コイル10との間の絶縁性も確保することができる。   Further, since the insulating member 12 is interposed between the wall 11 formed so as to surround the outer periphery of the primary side coil 1 and the outer periphery of the primary side coil 1, the primary side coil 1 and the secondary side coil 1 are arranged. Insulation with the coil 10 can also be ensured.

さらに、絶縁用カバー4内に収納されるコイル全体の外径寸法の増加量は、二次側コイル10における壁部11の板厚に絶縁部材12の厚さ寸法を加えた分だけであるために、実装面積が僅かに大きくなるに過ぎず、しかも壁部11は、一次側コイル1の外周側に屈曲形成されているために、高さ寸法は増加することがない。この結果、僅かな実装面積の増加により、二次側コイル10の断面積を効果的に増大させて一層の大電流化に対応することが可能になる。   Furthermore, the amount of increase in the outer diameter dimension of the entire coil housed in the insulating cover 4 is only the amount obtained by adding the thickness dimension of the insulating member 12 to the plate thickness of the wall portion 11 in the secondary coil 10. In addition, the mounting area is only slightly increased, and the wall 11 is bent at the outer peripheral side of the primary coil 1, so that the height dimension does not increase. As a result, by slightly increasing the mounting area, it is possible to effectively increase the cross-sectional area of the secondary coil 10 and cope with further increase in current.

なお、上記実施形態においては、本発明を一次側コイル1のボビン2の両端フランジ2aの外面に、それぞれ二次側コイル10が配置された2出力タイプのトランスに適用した場合についてのみ説明したが、本発明はこれに限定されるものではなく、一次側コイル1のボビン2の一方のフランジ2aの外面のみに二次側コイル10が配置された1出力タイプのトランスにも同様に適用することが可能である。   In the above embodiment, only the case where the present invention is applied to a two-output type transformer in which the secondary side coil 10 is arranged on the outer surface of the both end flange 2a of the bobbin 2 of the primary side coil 1 has been described. The present invention is not limited to this, and is similarly applied to a one-output type transformer in which the secondary coil 10 is disposed only on the outer surface of one flange 2a of the bobbin 2 of the primary coil 1. Is possible.
