本発明は、電磁継電器などに使用するコイル端子の接続
方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for connecting coil terminals used in electromagnetic relays and the like.
従来、この種のコイル端子の接続方法はスプールにイン
サート成形されたコイル端子にコイル巻線端を巻き付け
て半田ゴテにより半田固定するとともに、前記コイル端
子への外部端子の接続はスポット溶接などで接合してい
た。Conventionally, the method of connecting this type of coil terminal was to wrap the end of the coil winding around a coil terminal insert-molded on a spool and fix it by soldering with a soldering iron, and to connect an external terminal to the coil terminal by spot welding or the like. Was.
しかし、この接続方法によるとコイルの半田付けの際、

まう。However, according to this connection method, when soldering the coil,
First, the coil terminal is heated with a soldering iron, and then the solder is brought into contact with the heated part and melted to firmly connect the coil and coil terminal, so extra heating time is required to spread the solder to the coil terminal. As a result, the spool becomes deformed.
さらにコイルの半田接続とは別に外部端子をスポット溶
接でコイル端子に接合している関係上、組立工数がかか
るという欠点があった。Furthermore, since the external terminals are joined to the coil terminals by spot welding in addition to the solder connection of the coils, there is a drawback that assembly time is required.
本発明は、簡単な構成でもって従来の欠点を解消し、か
つ組立の合理化に寄与したコイル端子の接続方法を提供
しようとするものである。SUMMARY OF THE INVENTION The present invention aims to provide a method for connecting coil terminals that has a simple configuration, eliminates the drawbacks of the conventional method, and contributes to rationalization of assembly.
以下、本発明を図面にもとづいて説明する。Hereinafter, the present invention will be explained based on the drawings.

端子である。In the figure, 1 is a spool, 2 is a coil wound around spool 1,
3 is a coil terminal 4 which is solder-plated 6 and insert-molded into the spool 1, and is an external terminal that is fixed to a terminal block of a relay or the like.

わせる（第２図参照）。Next, to explain the method of connecting a coil terminal according to the present invention, the lead wires 2a and 2b of the coil 2 wound around the spool 1 are wound several times around the coil terminal 3 which has been subjected to solder plating 6, and then the coil terminal 3 is (See Figure 2).
つぎに重ね合わせたコイル端子３の上部を短時間に必要

る。Next, the upper part of the stacked coil terminals 3 is heated by a heating element 5 that supplies the necessary amount of heat in a short time, for example, by instantly melting the solder plating 6 applied to the coil terminals 3 in advance by reflow soldering method, the coil 2 is heated. leader lines 2a, 2b
The winding portion of the external terminal 4 and the external terminal 4 are connected simultaneously.
なお、コイル端子３と外部端子４との接合部は、どちら

合もより強固にできるものである。Note that the joint between the coil terminal 3 and the external terminal 4 has convex portions 4 a and 4 b on one side, and convex portions 4 a and 4 b on the other side.
, 4b are provided, the positioning of the coil terminal 3 and the external terminal 4 can be facilitated, and the connection can be made stronger.
さらに、コイル端子４は第４図に示すようにコイル巻回
部に切欠き部７を形成しておけばコイルの巻回がより確
実となる。Further, if the coil terminal 4 is provided with a notch 7 in the coil winding portion as shown in FIG. 4, the coil can be wound more reliably.

プールの変形を防止できる。According to the present invention, a coil terminal that has been solder-plated in advance is insert-molded into a spool, a winding wire wound around the spool is wound around the coil terminal, and then an external terminal is brought into contact with the coil terminal. The coil, coil terminal, and external terminal are fixed together by heating and melting the solder plating, which eliminates the time required to apply solder to the coil terminal after insert-molding the coil terminal on the spool. , the amount of heat transferred to the spool can be reduced to prevent deformation of the spool.
