【発明の詳細な説明】
本発明は、コイルに端子をはんだ付けする方法
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of soldering terminals to coils.
モールド変流器などのコイルを巻上げた場合
は、電線に端子を接続しなければならない。 When winding a coil such as a molded current transformer, terminals must be connected to the wire.
そのため第１図に示すような端子１を製作して
第２図に示すようにコイル２の電線にはんだ付け
する方法が行われていた。 Therefore, a method has been used in which a terminal 1 as shown in FIG. 1 is manufactured and soldered to the wire of a coil 2 as shown in FIG.
この場合、端子１は板１ａに袋部分１ｂを銀ロ
ウ付けして製作されるが、はんだ付けに際しては
第３図に示すように端子１の袋部分１ｂを上向き
にし、コイル２の電線を挿入してから融解したは
んだを流し込むため、袋部分１ｂの銀ロウ付けが
不完全であるとはんだが洩れるおそれがある。 In this case, the terminal 1 is manufactured by silver-brazing the bag portion 1b to the plate 1a, but when soldering, the bag portion 1b of the terminal 1 is turned upward as shown in Fig. 3, and the wire of the coil 2 is inserted. Since the molten solder is then poured into the bag portion 1b, there is a risk that the solder may leak if the silver brazing on the bag portion 1b is incomplete.
またコイル２の端子部分は、第２図に示すよう
に両側を向いているので、左右の端子を同時には
はんだ付けが出来ず、作業性も良くなかつた。 Further, since the terminal portions of the coil 2 face both sides as shown in FIG. 2, it is not possible to solder the left and right terminals at the same time, and the workability is not good.
また別の方法として、第４図に示すようにコイ
ル２の電線に端子板３を細い裸銅線４によりバイ
ンドしてからはんだ揚げする方法も行われている
が、バインドに手間がかかる上、表面に凹凸を生
じ易く、電気的および外観的にも感心できなかつ
た。 Another method, as shown in Fig. 4, is to bind the terminal plate 3 to the wire of the coil 2 with a thin bare copper wire 4 and then solder it, but the binding is time-consuming and The surface was prone to unevenness, and the electrical and appearance aspects were unsatisfactory.
またバインドを一々手で行うので、接続部分の
出来、不出来が発生する欠点もあつた。 Furthermore, since each binding is done by hand, there is also the drawback that the connection part may or may not be made properly.
本発明はこのような問題点を解消するために提
案されるもので、電熱体でありはんだが付きにく
い材料から成るつぼの中へはんだを入れ、つぼの
両側面に接続した電線から電流を通じてはんだを
溶解し、その中へコイルと端子を浸漬してはんだ
付けを行い、自然冷却又は強制冷却後つぼを外す
のである。 The present invention has been proposed to solve these problems. Solder is placed in a pot made of a material that is an electric heating element and is difficult to solder, and electric current is passed through electric wires connected to both sides of the pot to solder the pot. The coil and terminals are immersed in the melt and soldered, and the pot is removed after natural or forced cooling.
作業手順によつては、次のように順序を変えて
もよい。すなわちつぼの中へコイル端子を入れ、
つぼの両側面に接続した電線から電流を通じてつ
ぼを熱し、その後でハンダをつぼの中へ入れて融
解する。 Depending on the work procedure, the order may be changed as follows. In other words, put the coil terminal into the pot,
Electrical wires connected to both sides of the pot heat the pot, and then the solder is poured into the pot and melted.
第５図は本発明の実施例を示すものである。 FIG. 5 shows an embodiment of the invention.
図において、５ははんだ６を入れるつぼで電熱
体でありはんだが付きにくい材料、たとえばカー
ボンから成つている。また７はコイル２に取付け
るべき端子である。 In the figure, reference numeral 5 denotes a pot into which solder 6 is placed, which is an electric heating element and is made of a material that does not easily adhere to solder, such as carbon. Further, 7 is a terminal to be attached to the coil 2.
つぼ５にははんだ付け部分が抜きやすいように
テーパーを設けるとともに底部の隅は丸くしてあ
る。 The pot 5 is tapered so that the soldered part can be easily removed, and the bottom corner is rounded.
コイル２、つぼ５、端子７などは、治具８に取
付け支持されている。また９はつぼ５を治具８か
ら電気絶縁するための碍子である。 The coil 2, pot 5, terminal 7, etc. are attached and supported by a jig 8. Further, 9 is an insulator for electrically insulating the pot 5 from the jig 8.
第６図はつぼ５の部分を取出して示すもので、
つぼ５の両側面には任意の方法で電流１０が取付
けてある。 Figure 6 shows the pot 5 taken out.
Currents 10 are attached to both sides of the pot 5 in any desired manner.
このような構成において、まずコイル２と端子
７をつぼ５の中へセツトし、はんだ６を入れてか
らつぼ５に電流を通じると、つぼ５自身が発熱し
てはんだ６が溶解しコイル２と端子７ははんだ付
けされる。しかる後、電流を断つとはんだ６が冷
却され凝固するので、コイル２を持上げればはん
だ６部分はつぼから離れて取出すことができる。 In such a configuration, when the coil 2 and the terminal 7 are first set in the pot 5, and the solder 6 is put in, then a current is passed through the pot 5, the pot 5 itself generates heat, melts the solder 6, and the coil 2 and Terminal 7 is soldered. Thereafter, when the current is cut off, the solder 6 is cooled and solidified, so that by lifting the coil 2, the solder 6 can be removed from the pot.
作業時間短縮のため強制冷却（つぼ表面に水を
流すなど）を行えばさらに良結果が得られる。 Even better results can be obtained by using forced cooling (such as by running water over the surface of the pot) to shorten the working time.
本発明によれば次のような効果が得られる。 According to the present invention, the following effects can be obtained.
(1) つぼがはんだ溶解つぼとはんだ付け作業個所
を兼ねているので、溶解したはんだをはんだ付
け作業個所へ一々注入する手間が不要となり、
手作業がないので均一の製品が得られる。(1) Since the pot doubles as a solder melting pot and a soldering work area, there is no need to pour melted solder into each soldering work area one by one.
Since there is no manual work, a uniform product can be obtained.
(2) 端子に銀ロウ付けされた袋部分を設ける必要
がないので原価低減が可能となる。(2) Since there is no need to provide a silver-brazed bag part to the terminal, cost reduction is possible.
(3) つぼの内部に丸味が付けてあるのでエツジ部
分がなく、電気的および機械的に安定した製品
とすることができる。(3) Since the inside of the pot is rounded, there are no edges and the product can be electrically and mechanically stable.
(4) 作業を機械的作業化したので、動力による自
動化に寄与できる。(4) Since the work has been made mechanical, it can contribute to automation using power.
なお、本発明はコイル端子のはんだ付けのみな
らず、あらゆる金属製品・部品のはんだ付けに応
用できることは勿論である。 It goes without saying that the present invention can be applied not only to the soldering of coil terminals but also to the soldering of all metal products and parts.
