Description

本発明のラインフィルタでは、さらなる好ましい特徴として、「前記保持部は、前記第１筒状胴部と前記第２筒状胴部の間に配された有底四角筒状部であり、前記保持部の開口方向は、前記第１筒状胴部と前記第２筒状胴部の軸方向と直角方向に形成されていること」、「前記保持部は、前記ノーマルモードコアの挿入方向において前記ノーマルモードコアが当接する当接部を有し、前記ノーマルモードコアが前記保持部に挿入されて前記当接部に当接すると、前記コモンモードコアと前記ノーマルモードコアの磁束を調整できること」、「前記ノーマルモードコアの上端は、前記保持部の上端と同一の高さ以下に配されている、または、前記第１ボビンの前記第１筒状胴部と前記第２ボビンの前記第２筒状胴部の両側にそれぞれ設けられた鍔部の上端と同一の高さ以下に配されていること」、を含むものである。 In the line filter of the present invention, as a further preferable feature, “the holding part is a bottomed rectangular cylindrical part disposed between the first cylindrical body part and the second cylindrical body part, The opening direction of the part is formed in a direction perpendicular to the axial direction of the first cylindrical body part and the second cylindrical body part. "" The holding part is in the insertion direction of the normal mode core. The normal mode core has an abutting portion that abuts, and when the normal mode core is inserted into the holding portion and abutted against the abutting portion, the magnetic flux of the common mode core and the normal mode core can be adjusted. '' “The upper end of the normal mode core is arranged below the same height as the upper end of the holding part, or the first cylindrical body of the first bobbin and the second cylinder of the second bobbin. Provided on both sides of the body It is arranged below the same height as the upper end of the flange.
