従来、巻線コイルが使用されるモータ,電磁型電気音響機器等の電磁機器では、巻線の端末と端子の接続部との接続に半田付けを使用していた。
巻線は絶縁被膜層を有しているので、巻線の端末と端子の接続部との半田付け接続の際には、端末における巻線の絶縁被膜層を除去する必要がある。
近年では、より高温に耐えられるような絶縁被膜層(例えば、溶融温度 250℃〜 350℃の絶縁被膜層)を有する耐熱用の巻線が使用されるようになっているが、この耐熱用の巻線の絶縁被膜層を、半田を溶融させる際の加熱によって除去するのは困難であった。この為、従来では、巻線の端末と端子の接続部との接続作業の前に、巻線の絶縁被膜層の剥離作業が必要となっていた。この巻線の絶縁被膜層を剥離するには、機械的に剥離する方法や、その他の方法がとられていた(例えば、特許文献1参照)。
Conventionally, in an electromagnetic device such as a motor and an electromagnetic electroacoustic device in which a winding coil is used, soldering is used for connection between the terminal of the winding and the connection portion of the terminal.
Since the winding has an insulating coating layer, it is necessary to remove the insulating coating layer of the winding at the terminal when soldering the terminal of the winding and the connecting portion of the terminal.

It has been difficult to remove the insulating coating layer of the winding by heating when melting the solder. For this reason, conventionally, before the work of connecting the terminal of the winding and the connection portion of the terminal, it is necessary to peel off the insulating coating layer of the winding. In order to peel off the insulating coating layer of this winding, a mechanical peeling method or other methods have been employed (for example, see Patent Document 1).
特許文献1では、巻線の端末を端子上に配置する工程と、巻線の絶縁被膜層をレーザ光の加熱光で除去して芯線を露出させる工程と、端末と端子の接続部について半田付けする工程と、を具備した巻線の端末接続方法が開示されている。

次に、図1〜図4に基づいて、本発明の第1実施形態に係る巻線の端末接続方法の詳細を順を追って説明する。
まず、図1に示すように、絶縁被膜層1を有する複数本の巻線10…の端末3を、端子5の接続部6にロウ材4と共に設置する(図1の矢印A方向)。より詳しくは、接続部6の載置部8に複数本の巻線10…の端末3を並べて載置し、さらに、端末3の上に板状のロウ材4を載置する。なお、載置部8に設置される端末3及びロウ材4の大きさは、一対の側壁部9,9の間に丁度納まる大きさ(左右への大きながたつきが生じない大きさ)に設定されている。
次に、図示省略のかしめ工具にて、接続部6の一対の側壁部9,9を内側(図1の矢印B側)に折曲げる。この接続部6の塑性加工にて、端末3とロウ材4とを仮保持する。
Next, details of the winding terminal connection method according to the first embodiment of the present invention will be described in order based on FIGS.
First, as shown in FIG. 1, the terminals 3 of the plurality of windings 10 having the insulating coating layer 1 are installed together with the brazing material 4 on the connection portion 6 of the terminal 5 (in the direction of arrow A in FIG. 1). More specifically, the terminals 3 of the plurality of windings 10 are placed side by side on the placement portion 8 of the connection portion 6, and the plate-like brazing material 4 is placed on the terminals 3. In addition, the size of the terminal 3 and the brazing material 4 installed on the mounting portion 8 is just large enough to fit between the pair of side wall portions 9 and 9 (a size that does not cause large rattling on the left and right). Is set.
Next, the pair of side wall portions 9 and 9 of the connecting portion 6 are bent inward (arrow B side in FIG. 1) with a caulking tool (not shown). The terminal 3 and the brazing material 4 are temporarily held by the plastic working of the connecting portion 6.
このように、接続部6において端末3とロウ材4とを仮保持した状態で、次に図2に示すように、端子5を下側の電極7bに載置する。このとき、接続部6が上下一対の電極7a,7b間の所定の場所に位置するようにする。
次に、図3に示すように、一対の電極7a,7bを相互に接近させて、端末3とロウ材4とを接続部6にて巻付塑性変形するように押圧(図3の矢印F方向)しながら、接続部6に電流I(図3の矢印I方向)を流して加熱し、絶縁被膜層1…を溶融除去すると共にロウ材4を溶融する。
この際、電流Iは、一対の側壁部9,9に沿って、かつ、均等に流れる。これにより、側壁部9,9は、全体的にバランスよく温度が上昇する。また、側壁部9,9は、端末3及びロウ材4の側面に巻付状とされるので、端末3及びロウ材4は全体的にバランスよく加熱される。この加熱は、ロウ材4の溶融温度( 600℃〜1000℃)にて行なわれ、端末3における巻線10…の絶縁被膜層1…(溶融温度 250℃〜 350℃)は、ほぼ完全に溶融除去される。また、この加熱により溶融状態のロウ材4は均一に広がって、端末3と、端末3に包囲状となった側壁部9,9及び載置部8との間の空間を塞ぐ。
こうして、巻線10…の端末3と端子5の接続部6との接続作業が終了し、図4の状態となる。
In this manner, with the terminal 3 and the brazing material 4 temporarily held at the connection portion 6, the terminal 5 is placed on the lower electrode 7b as shown in FIG. At this time, the connecting portion 6 is positioned at a predetermined location between the pair of upper and lower electrodes 7a and 7b.
Next, as shown in FIG. 3, the pair of electrodes 7a and 7b are brought close to each other and pressed so that the terminal 3 and the brazing material 4 are wound and plastically deformed at the connecting portion 6 (arrow F in FIG. 3). Direction), a current I (in the direction of arrow I in FIG. 3) is passed through the connecting portion 6 and heated to melt and remove the insulating coating layers 1 and melt the brazing material 4.
At this time, the current I flows evenly along the pair of side wall portions 9 and 9. Thereby, the temperature of the side wall parts 9 and 9 rises with a good balance as a whole. Moreover, since the side wall parts 9 and 9 are wound around the side surfaces of the terminal 3 and the brazing material 4, the terminal 3 and the brazing material 4 are heated with a good balance as a whole. This heating is performed at the melting temperature (600 ° C. to 1000 ° C.) of the brazing material 4, and the insulating coating layer 1 (melting temperature 250 ° C. to 350 ° C.) of the windings 10 at the terminal 3 is almost completely melted. Removed. Further, the brazing material 4 in a molten state spreads uniformly by this heating, and closes the space between the terminal 3 and the side wall portions 9 and 9 and the mounting portion 8 surrounded by the terminal 3.
Thus, the connection work between the terminal 3 of the windings 10 and the connection portion 6 of the terminal 5 is completed, and the state shown in FIG. 4 is obtained.
図5〜図8は、本発明の第2の実施の形態に係る巻線の端末接続方法を説明するための図である。第2実施形態では、第1実施形態と異なり、端末3とロウ材4とを仮保持する作業を省略する場合を例示している。また、第2実施形態では、第1実施形態と比較して、端子5の接続部6の形状が異なっている。具体的には、各側壁部9は最初から内側に少し傾いた形状となっている。また、各側壁部9の先端部外側には、アール部9aが形成されている。その他の端子5の形状(載置部8等)は、第1実施形態と同様である。
また、接続部6の載置部8に設置されるロウ材4や巻線10…の端末3の形状も、第1実施形態と同様である。また、上下一対の電極7a,7bの構造も、第1実施形態と同様である。
FIG. 5 to FIG. 8 are diagrams for explaining a winding terminal connection method according to the second embodiment of the present invention. Unlike the first embodiment, the second embodiment exemplifies a case where the work of temporarily holding the terminal 3 and the brazing material 4 is omitted. Moreover, in 2nd Embodiment, the shape of the connection part 6 of the terminal 5 differs compared with 1st Embodiment. Specifically, each side wall 9 has a shape slightly inclined inward from the beginning. Further, a rounded portion 9 a is formed on the outer side of the distal end portion of each side wall portion 9. Other shapes of the terminal 5 (such as the placement portion 8) are the same as those in the first embodiment.
Moreover, the shape of the terminal 3 of the brazing material 4 and the windings 10 installed on the mounting portion 8 of the connection portion 6 is the same as that of the first embodiment. The structure of the pair of upper and lower electrodes 7a and 7b is the same as that of the first embodiment.
次に、図5〜図8に基づいて、本発明の第2実施形態に係る巻線の端末接続方法の詳細を順を追って説明する。
まず、図5に示すように、絶縁被膜層1を有する複数本の巻線10…の端末3を、端子5の接続部6にロウ材4と共に設置する(図5の矢印D方向)。より詳しくは、接続部6の載置部8に端末3を載置し、さらに、端末3の上に板状のロウ材4を載置する。なお、載置部8に設置される端末3及びロウ材4の大きさは、一対の側壁部9,9の間に丁度納まる大きさ(左右への大きながたつきが生じない大きさ)に設定されている。
Next, based on FIGS. 5-8, the detail of the terminal connection method of the coil | winding which concerns on 2nd Embodiment of this invention is demonstrated later on.
First, as shown in FIG. 5, the terminals 3 of the plurality of windings 10 having the insulating coating layer 1 are installed together with the brazing material 4 on the connection portion 6 of the terminal 5 (in the direction of arrow D in FIG. 5). More specifically, the terminal 3 is placed on the placement portion 8 of the connection portion 6, and the plate-like brazing material 4 is placed on the terminal 3. In addition, the size of the terminal 3 and the brazing material 4 installed on the mounting portion 8 is just large enough to fit between the pair of side wall portions 9 and 9 (a size that does not cause large rattling on the left and right). Is set.
次に、図6に示すように、接続部6に端末3とロウ材4とが設置された状態で、端子5を下側の電極7bに載置する。このとき、接続部6が上下一対の電極7a,7b間の所定の場所に位置するようにする。
次に、図6及び図7に示すように、一対の電極7a,7bを相互に接近させて(図6の矢印G方向)、端末3とロウ材4とを接続部6にて巻付塑性変形するように押圧(図7の矢印F方向)しながら、接続部6に電流I(図7の矢印I方向)を流して加熱し、絶縁被膜層1を溶融除去すると共にロウ材4を溶融する。
より詳しくは、一対の電極7a,7bは、接続部6の側壁部9,9の先端部分が上側の電極7aの凹窪部11に入るようにして、相互に接近させる。そして、凹窪部11を形成する壁面に側壁部9,9の先端部分が接触した後、さらに電極7a,7bを相互に接近させることにより、側壁部9,9を内側(図6の矢印E側)に折曲げるようにする。この際、各側壁部9は、先端部の外側に設けられたアール部9aにより、スムーズに折り曲げられる。つまり、第2実施形態では、第1実施形態の(かしめ工具で側壁部9,9を折曲げる)仮保持の作業が省略されることとなる。
Next, as illustrated in FIG. 6, the terminal 5 is placed on the lower electrode 7 b in a state where the terminal 3 and the brazing material 4 are installed in the connection portion 6. At this time, the connecting portion 6 is positioned at a predetermined location between the pair of upper and lower electrodes 7a and 7b.
Next, as shown in FIGS. 6 and 7, the pair of electrodes 7 a and 7 b are brought close to each other (in the direction of arrow G in FIG. 6), and the terminal 3 and the brazing material 4 are wound around the connecting portion 6. While pressing so as to deform (in the direction of arrow F in FIG. 7), current I (in the direction of arrow I in FIG. 7) is passed through the connecting portion 6 and heated to melt and remove the insulating coating layer 1 and melt the brazing material 4 To do.
More specifically, the pair of electrodes 7a and 7b are brought close to each other so that the tip end portions of the side wall portions 9 and 9 of the connecting portion 6 enter the recessed portion 11 of the upper electrode 7a. And after the front-end | tip part of the side wall parts 9 and 9 contacted the wall surface which forms the hollow part 11, the electrode 7a and 7b are made to approach mutually, and the side wall parts 9 and 9 are made inside (arrow E of FIG. 6). Bend to the side). At this time, each side wall 9 is smoothly bent by the rounded portion 9a provided outside the tip. That is, in the second embodiment, the temporary holding operation (folding the side walls 9 and 9 with a caulking tool) of the first embodiment is omitted.
また、端末3とロウ材4とを接続部6にて巻付塑性変形するように押圧する際、電流Iは、一対の側壁部9,9に沿って、かつ、均等に流れる。これにより、側壁部9,9は、全体的にバランスよく温度が上昇する。また、側壁部9,9は、端末3及びロウ材4の側面に巻付状とされるので、端末3及びロウ材4は全体的にバランスよく加熱される。この加熱は、ロウ材4の溶融温度( 600℃〜1000℃)にて行なわれるので、端末3における巻線10…の絶縁被膜層1…(溶融温度 250℃〜 350℃)は、ほぼ完全に溶融除去される。また、この加熱により溶融状態のロウ材4は均一に広がって、端末3と、端末3に包囲状となった側壁部9,9及び載置部8との間の空間を塞ぐ。
こうして、巻線10…の端末3と端子5の接続部6との接続作業が終了し、図8の状態となる。
Further, when the terminal 3 and the brazing material 4 are pressed so as to be wound and plastically deformed at the connection portion 6, the current I flows along the pair of side wall portions 9 and 9 evenly. Thereby, the temperature of the side wall parts 9 and 9 rises with a good balance as a whole. Moreover, since the side wall parts 9 and 9 are wound around the side surfaces of the terminal 3 and the brazing material 4, the terminal 3 and the brazing material 4 are heated with a good balance as a whole. Since this heating is performed at the melting temperature of the brazing material 4 (600 ° C. to 1000 ° C.), the insulating coating layer 1 of the windings 10 at the terminal 3 (melting temperature 250 ° C. to 350 ° C.) is almost completely Melted and removed. Further, the brazing material 4 in a molten state spreads uniformly by this heating, and closes the space between the terminal 3 and the side wall portions 9 and 9 and the mounting portion 8 surrounded by the terminal 3.
Thus, the connection work between the terminal 3 of the windings 10 and the connection portion 6 of the terminal 5 is completed, and the state shown in FIG. 8 is obtained.
なお、本発明は、上述の実施の形態に限定されず、本発明の要旨を逸脱しない範囲で設計変更可能である。例えば、本実施形態では、ロウ材4は、板状である場合を例示したが、本発明はこれに限らず、ロウ材4を棒状としてもよい。また、巻線10…の端末3と共に端子5の接続部6に設置するロウ材4の数を、複数にしてもよい。
また、ロウ材4は、リン銅ロウに限るのではなく、他の種類のロウ材を用いてもよい。例えば、銀ロウを用いてもよい。
The present invention is not limited to the above-described embodiment, and the design can be changed without departing from the gist of the present invention. For example, in the present embodiment, the case where the brazing material 4 has a plate shape is illustrated, but the present invention is not limited to this, and the brazing material 4 may have a rod shape.
