Description
【０００１】
【発明の属する技術分野】
本発明は、小型の高圧トランス、リレーコイル、イグニッションコイル等に用いられるコイルボビンに関する。
【０００２】
【従来の技術】
一般にコイルボビンは、その両端に設けられた鍔部の一端面を幅の広い端子保持部として、この端子保持部にＬ型接続端子を植設している。このボビンの鍔部の側面に沿って廻したコイルの端部は、前記Ｌ型接続端子とも平行に沿ってＬ型接続端子にカラゲ廻しされ、半田付けされるようになっている。
【０００３】
【発明が解決しようとする課題】
小型の高圧トランス等をプリント配線基板に搭載する際に、接続端子が外部からの影響を受けた場合、例えば周囲の部品に接触するような場合、接続端子が動き、線材に断線が発生するという問題がある。
【０００４】
そこで本発明は、接続端子にカラゲ廻されて半田付けされるコイルの端部に余裕を持たせることで、コイルの断線を防止するようにしたコイルボビンを提供することを目的とするものである。
【０００５】
【課題を解決するための手段】
上記目的を達成するため、本発明は、鍔部に形成された端子保持部に接続端子を設け、コイルの端部を前記接続端子に巻き付けて半田付けするコイルボビンにおいて、
前記コイルの端部を引き出す案内保持部を設けて、
その案内保持部より低い位置で前記接続端子が前記端子保持部に保持され、
前記案内保持部と前記接続端子を保持した端子保持部の間に段差が形成され、
前記コイルの端部を前記案内保持部上に引き出してから前記段差を通って前記接続端子に巻き付けることにより、前記案内保持部と前記接続端子との間において、前記コイルの端部が角度θ1をもって斜めに設けられていることを特徴とするものである。
【０００６】
また、第２の手段は、前記第１の手段において、前記案内保持部の上から見たときに前記コイルの端部が前記案内保持部から前記接続端子に向かって角度θ２をもって斜めに引き出されていることを特徴とするものである。
【０００７】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。図１は本発明の実施の形態に係るコイルボビンの正面図、図２は図１の矢印イ方向視図、図３は図１の矢印ロ方向視図、図４は図１のハで示す部分の拡大図である。
【０００８】
これらの図において、１はコイルボビン、２はＬ型接続端子、３は端子保持部、４は案内保持部、５は段差、６はコイル（電線）をそれぞそれ示す。
【０００９】
コイルボビン１はその両端の鍔部の一端面に幅の広い端子保持部３を形成し、Ｌ型接続端子２は端子保持部３に植設されている。コイル６の端部は案内保持部４上を廻されるようになっている。
【００１０】
本実施の形態では、図２、図３に示されるように、端子保持部３の孔３ａにＬ型接続端子２が嵌入されることで、Ｌ型接続端子２は端子保持部３に保持されるが、この孔３ａの位置は案内保持部４より低くなっている。
【００１１】
従って、案内保持部４上に引き出されたコイル６の端部とＬ型接続端子２の間にθ１で示す角度が生じることになる。
【００１２】
なお、図４に示す正面から見ても、角度θ２が付けられるように端子保持部３の一端が案内保持部４より突出している。
【００１３】
このように、コイル６の端部とＬ型接続端子２との間に角度を設けることで、コイル６の端部に余裕を持たせることができる。また端子上部に沿ってカラゲ廻して半田付けすることができる。
【００１４】
【発明の効果】
本発明によれば、鍔部に形成された端子保持部に接続端子を設け、コイルの端部を前記接続端子に巻き付けて半田付けするコイルボビンにおいて、前記コイルの端部を引き出す案内保持部を設けて、その案内保持部より低い位置で前記接続端子が前記端子保持部に保持され、前記案内保持部と前記接続端子を保持した端子保持部の間に段差が形成され、前記コイルの端部を前記案内保持部上に引き出してから前記段差を通って前記接続端子に巻き付けることにより、前記案内保持部と前記接続端子との間において、前記コイルの端部が角度θ1をもって斜めに設けられているので、コイルの端部に余裕を持たせることができ、断線を防止することが可能となる。

BACKGROUND OF THE INVENTION
The present invention relates to a coil bobbin used for a small high voltage transformer, a relay coil, an ignition coil and the like.
[0002]
[Prior art]
In general, the coil bobbin has one end surface of a collar provided at both ends thereof as a wide terminal holding portion, and L-type connection terminals are implanted in the terminal holding portion. The end portion of the coil that is turned along the side surface of the flange portion of the bobbin is turned around and soldered to the L-type connection terminal in parallel with the L-type connection terminal.
[0003]
[Problems to be solved by the invention]
When mounting a small high-voltage transformer or the like on a printed wiring board, if the connection terminal is affected by the outside, for example, if it touches the surrounding parts, the connection terminal will move and the wire will break. There's a problem.
