【課題を解決するための手段】
本発明は、上記目的を達成するために、筒状ボビンと、該筒状ボビン内に挿入した棒状コアと、前記筒状ボビンの外周に装着した筒状コイル体と、からなるインダクタンス素子において、前記筒状ボビンは、一方の開口端に凹凸嵌合部および鍔片を、また他の開口端に当接片をそれぞれ設けた二個のボビン素体の、それぞれの前記凹凸嵌合部を相互に嵌合して構成し、前記当接片を前記棒状コアの端面に当接して前記筒状ボビン内に前記棒状コアを装着するとともに、前記筒状ボビンの外周に装着した固定リングと前記鍔片との間の前記筒状ボビンの外周に前記筒状コイル体を装着し、前記鍔片に、前記筒状コイル体の巻き始め引き出し線又は巻き終わり引き出し線を係止する第１係止片を設け、前記固定リングに、前記巻き始め引き出し線又は前記巻き終わり引き出し線を係止する第２係止片を設けたことを特徴としている。 0008
[Means for solving problems]
The present invention comprises an inductance element comprising a tubular bobbin, a rod-shaped core inserted into the tubular bobbin, and a tubular coil body mounted on the outer periphery of the tubular bobbin in order to achieve the above object. The tubular bobbin has two bobbin elements having an uneven fitting portion and a flange piece at one opening end and a contact piece at the other opening end, and each of the uneven fitting portions is mutually provided. The rod-shaped core is mounted in the tubular bobbin by abutting the contact piece against the end face of the rod-shaped core, and the fixing ring and the flange mounted on the outer periphery of the tubular bobbin. A first locking piece in which the tubular coil body is attached to the outer periphery of the tubular bobbin between the pieces, and the winding start lead wire or the winding end lead wire of the tubular coil body is locked to the flange piece. The fixing ring is provided with a second locking piece for locking the winding start lead wire or the winding end lead wire.

さらに本発明は、筒状コイル体の巻き始め引き出し線又は巻き終わり引き出し線が所定位置に固定されるため、インダクタンス素子の端子棒として両引き出し線をそのまま用いることができる。また、従来のように両引き出し線をインダクタンス素子の端子棒に巻き付けて半田付けする作業を行う必要が無くなり、インダクタンス素子の製造工数が減少される。 Further, in the present invention, since the winding start wire or the winding end lead wire of the tubular coil body is fixed at a predetermined position, both lead wires can be used as they are as the terminal rod of the inductance element. Further, it is not necessary to wind and solder both lead wires around the terminal rod of the inductance element as in the conventional case, and the man-hours for manufacturing the inductance element is reduced.

Claims
