より、変成器をプリント基板７に固定するわけであるが
、この場合、プリント基板７に振動が加わることにより
変成器も前後左右にがたついて端子脚２が半田付けされ
た銅箔部８の一部が割れたり、さらには箔浮きが生じる

象を防止していた。Attach ferrite cores 3 and 4 as above, and coil 5
With the lead wire 6 wrapped around the terminal leg 2 and soldered, insert the terminal leg 2 into the predetermined hole of the printed circuit board 7 as shown in FIG.
The transformer is fixed to the printed circuit board 7 by inserting the tip of the transformer and soldering it to the copper foil section 8 on the back side. In order to prevent the part of the copper foil part 8 to which the terminal leg 2 is soldered to from rattling and cracking, or even to prevent the foil from lifting, a center penetrating hole is formed on the lower surface of the third wing piece 1C of the bobbin 1. A pair of auxiliary legs 9 are positioned close to the hole.
are integrally protruded, and the tips of the auxiliary legs 9 are attached to the printed circuit board 7.
The soldering of the terminal leg 2 prevents the above-mentioned phenomenon.
ここで、１０は半田を示す。Here, 10 indicates solder.
一方、上記変成器を作製する手順をみると、まずボビン
１にコイル５を巻き、その両端引出線６を端子脚２に巻
付け、さらにこの部分を半田付けするのであるが、補助
脚９が突出している関係上、半田槽による自動半田付け
が行えず、半田ごてによる手作業により半田付けを行う
ため作業能率が悪いという問題があった。On the other hand, looking at the procedure for manufacturing the above-mentioned transformer, first the coil 5 is wound around the bobbin 1, the lead wires 6 at both ends of the coil are wound around the terminal leg 2, and this part is further soldered. Due to the protrusion, automatic soldering using a solder bath cannot be performed, and soldering is performed manually using a soldering iron, resulting in poor work efficiency.
そこで、本考案はボビンの形状に改良を加えることによ
り、引出線の端子脚への半田付作業を、半田が溶解して
いる静止半田槽を用いて自動半田付けが行えるようにし
たものである。Therefore, in this invention, by improving the shape of the bobbin, it is possible to automatically solder the lead wire to the terminal leg using a stationary solder tank in which the solder is melted. .
以下その一実施例を第３図、第４図を用いて説明する。An example of this will be described below with reference to FIGS. 3 and 4.
なお、第１図と同一部品には同一番号を附して説明する
。Note that the same parts as in FIG. 1 are given the same numbers and explained.
本変成器の特徴とする点はボビン１１にあり、従来と同
様に第１〜第３の翼片１１ａ。The feature of this transformer is the bobbin 11, which has the first to third blades 11a as in the conventional case.
１１ ｂ、１１ Ｃを一体に形成し、第３の翼片１１
Ｃに端子脚２を固定するようにするとともに、一対の補
助脚１２をボビン１１の中央貫通孔の径方向に突出する
ように一体に形成している。11 b and 11 C are integrally formed, and the third wing piece 11
The terminal leg 2 is fixed to C, and a pair of auxiliary legs 12 are integrally formed so as to protrude in the radial direction of the central through hole of the bobbin 11.
そして、前記補助脚１２はその基部の下面側に略Ｕ字状
あるいは略■字状の切欠溝１３を形成することにより薄
肉部１４を形成して、補助脚１２が薄肉部１４を支点に
して回動するように構成している。The auxiliary leg 12 forms a thin wall portion 14 by forming a substantially U-shaped or substantially square-shaped cutout groove 13 on the lower surface side of its base, and the auxiliary leg 12 uses the thin wall portion 14 as a fulcrum. It is configured to rotate.
したがって上記構成によれば、補助脚１２を形成した状
態では、補助脚１２が第３の翼片１１ Ｃと同一面上に
あるため、ボビン１１に巻着されたコイル５の引出線６
を端子脚２に半田付けする場合、第３図に示すように半
田槽１５上にボビン１１を位置せしめることにより引出
線６と端子脚２の半田付けが可能となる。Therefore, according to the above configuration, when the auxiliary leg 12 is formed, since the auxiliary leg 12 is on the same plane as the third wing piece 11C, the lead wire 6 of the coil 5 wound around the bobbin 11
When soldering the lead wire 6 to the terminal leg 2, the lead wire 6 and the terminal leg 2 can be soldered by positioning the bobbin 11 on the solder bath 15 as shown in FIG.
したがって従来にくらべて半田付作業ははるかに容易と
なる。Therefore, soldering work is much easier than in the past.
次にこの半田付作業が終了した後、Ｅ型フェライトコア
３をボビン１１に装着するが、このときＥ型フェライト
コア３を第４図のごとく矢印Ａ方向に差込むことにより
Ｅ型フェライトコア３の中央脚が補助脚１２を矢印Ｂ方
向に開くことになり、結局補助脚１２は第３の翼片１１
Ｃに対して垂直状態になる。Next, after completing this soldering work, the E-type ferrite core 3 is attached to the bobbin 11. At this time, the E-type ferrite core 3 is inserted in the direction of arrow A as shown in FIG. The central leg opens the auxiliary leg 12 in the direction of arrow B, and the auxiliary leg 12 eventually opens the third wing piece 11.
It becomes perpendicular to C.
そして上記変成器をプリント基板７上に装着すると、補
助脚１２は従来と同様にその先端がプリント基板７に当
接し、振動による端子脚２の半田付は部分の箔割れ、箔
浮きを防止することができる。When the transformer is mounted on the printed circuit board 7, the tip of the auxiliary leg 12 comes into contact with the printed circuit board 7 as in the conventional case, and the soldering of the terminal leg 2 due to vibration prevents the foil from breaking or lifting. be able to.
以上説明したように本考案によれば、従来では補助脚が
障害となって自動半田付作業が不可能であったのに対し
て、半田付作業時には補助脚が第３の翼片と面一になっ
ているためコイル引出線と端子脚との自動半田付けが可
能となり、作業性が向上する。As explained above, according to the present invention, the auxiliary leg becomes an obstacle and automatic soldering work is impossible in the past, but during soldering work, the auxiliary leg is flush with the third wing piece. This makes it possible to automatically solder the coil lead wire and terminal leg, improving work efficiency.
また、補助脚はコアの装着により自動的に端子脚と平行
になるように移動（回動）するため、補助脚を回動させ
る作業も容易となるものである。Further, since the auxiliary leg automatically moves (rotates) parallel to the terminal leg when the core is attached, the operation of rotating the auxiliary leg becomes easy.
