Description
【０００１】[0001]
本考案は、例えば磁石発電機の発電コイル等のコイルの端末線が端子金具に半 田付け接続されているコイルの端末接続部に関するものである。 The present invention relates to a terminal connecting portion of a coil in which a terminal wire of a coil such as a magneto coil of a magnet generator is connected to a terminal fitting by soldering.
【０００２】[0002]
例えば、磁石発電機の発電コイル等のコイルが絶縁被覆細線で形成されていて 、このコイルの端末線にそれより太い口出線（出力線）を接続する場合、両者を 直接半田付け接続する場合もあるが、接続部の強度の関係や該接続部の位置決め の関係等で一般にはコイルの端末線を端子金具に一旦半田付け接続し、この端子 金具に口出線を半田付け接続することが行われている。 For example, when a coil such as a generator coil of a magnet generator is formed of an insulating thin wire, and when connecting a thicker lead wire (output wire) to the terminal wire of this coil, or when connecting both by direct soldering Depending on the strength of the connecting part and the positioning of the connecting part, it is generally possible to solder the terminal wire of the coil to the terminal fitting once and then connect the lead wire to the terminal fitting. Has been done.
【０００３】 この場合、コイルの端末線を端子金具に半田付け接続するに際し、コイルの端 末線が細線では半田付け部の強度不足の恐れがあるので、一般には図５（Ａ）に 示すようにコイルの端末線１の先端側を所定の長さで逆向きに２回折り返し、次 に図５（Ｂ）に示すようにこの折り返し線部分を撚り合わせて見掛け上３本の線 からなる機械的強度の大きい撚線部２を構成し、この撚線部２を端子金具に半田 付け接続している。In this case, when the terminal wire of the coil is soldered and connected to the terminal fitting, if the terminal wire of the coil is a thin wire, the strength of the soldered portion may be insufficient. Therefore, as shown in FIG. Then, the tip end side of the coil end wire 1 is folded back in a predetermined length in the opposite direction twice, and then, as shown in FIG. 5 (B), the folded wire portion is twisted and apparently made up of three wires. The stranded wire portion 2 having a high mechanical strength is formed, and the stranded wire portion 2 is connected to the terminal fitting by soldering.
【０００４】 通常、このような撚線部２を端子金具に半田付け接続するに際しては、この撚 線部２を構成している絶縁被覆細線からなる端末線１の絶縁被覆を剥がして半田 付けする必要がある。Normally, when such a stranded wire portion 2 is soldered and connected to a terminal fitting, the insulation coating of the terminal wire 1 which is a thin wire with an insulation coating forming the stranded wire portion 2 is peeled off and soldered. There is a need.
【０００５】 一番好ましいのは、撚線部２を構成する前に、この撚線部２を構成するに必要 な長さの端末線１の部分の全長の絶縁被覆を剥がすのがよいが、絶縁被覆細線か らなる端末線１で撚線部２を構成する予定長の全長の絶縁被覆を剥がすのは、線 が細く切れ易い関係で、非常に困難である。Most preferably, before forming the twisted wire portion 2, the entire length of the insulation coating of the portion of the terminal wire 1 having a length required to form the twisted wire portion 2 is peeled off. It is very difficult to remove the insulation coating of the entire length of the planned length that constitutes the stranded wire portion 2 from the terminal wire 1 made of the insulation-coated thin wire because the wire is thin and easily cut.
【０００６】 そこで、通常は撚線部２を構成してからその外周の絶縁被覆をサンドペーパー 等で機械的に除去していた。Therefore, usually, the stranded wire portion 2 is formed and then the insulating coating on the outer periphery thereof is mechanically removed by sandpaper or the like.
【０００７】[0007]
しかしながら、絶縁被覆細線からなる端末線１の撚線部２を構成してからその 外周の絶縁被覆をサンドペーパー等で機械的に除去する方法では、図６に示すよ うに見掛け上３本の端末線１の導体１ａの撚り合わせ体からなる撚線部２の中心 部側の絶縁被覆１ｂの除去ができず、端子金具に対する半田付け接続が良好に行 えない問題点があった。 However, in the method in which the twisted wire portion 2 of the terminal wire 1 made of the insulating coated thin wire is constructed and then the insulating coating on the outer periphery thereof is mechanically removed with sandpaper or the like, as shown in FIG. There was a problem that the insulation coating 1b on the center side of the twisted wire portion 2 made of a twisted body of the conductor 1a of the wire 1 could not be removed, and the soldering connection to the terminal fitting could not be performed properly.
【０００８】 また、コイルを構成する絶縁被覆細線の絶縁被覆がイミド系樹脂で形成されて いる場合には、導体に対する付着力が大きいためサンドペーパーでこすると該導 体も削られて該導体の強度が低下してしまうので、バーナで焼き、その後に酸化 面を機械的に除去する等の方法を取らざるを得ず、被覆除去長さが長いと非常に 手数がかかる問題点があった。Further, when the insulation coating of the insulation-coated thin wire forming the coil is formed of an imide resin, the adhesion to the conductor is large, and therefore the conductor is also scraped by rubbing with sandpaper and the conductor is scraped. Since the strength decreases, there is no choice but to take a method such as baking with a burner and then mechanically removing the oxidized surface, and there is a problem that a long coating removal length is very troublesome.
【０００９】 本考案の目的は、コイルの端末線の絶縁被覆の除去が簡単で、しかも機械的強 度も大きいコイルの端末接続部を提供することにある。It is an object of the present invention to provide a coil terminal connecting portion in which the insulation coating on the coil terminal wire can be easily removed and which has high mechanical strength.
【００１０】 本考案の他の目的は、コイルの端末線の絶縁被覆の除去が簡単で、しかも機械 的強度の補強に用いる補強導線の絶縁被覆の除去も不要となるコイルの端末接続 部を提供することにある。Another object of the present invention is to provide a coil terminal connecting portion in which removal of an insulating coating of a coil terminal wire is easy and removal of an insulating coating of a reinforcing conductor used for reinforcing mechanical strength is unnecessary. To do.
【００１１】 本考案の他の目的は、温度上昇が問題となるコイルでも、その端末線の絶縁被 覆の除去が簡単で、しかも機械的強度の補強に用いる補強導線の絶縁被覆の除去 も不要となるコイルの端末接続部を提供することにある。Another object of the present invention is to easily remove the insulation coating of the terminal wire of a coil, which causes a problem of temperature rise, and does not require removal of the insulation coating of the reinforcing conductor used for reinforcing the mechanical strength. It is to provide a terminal connection portion of the coil.

The conductor wires are vertically attached and twisted together, and the twisted wire portions of the bare conductor and the reinforcing conductor wire are soldered to the terminal fittings.
【００１６】 また本考案においては、イミド系樹脂被覆導線で形成されたコイルの端末線が 端子金具に半田付け接続されている構造のコイルの端末接続部において、前記コ イルの端末線の接続端部はその絶縁被覆が除去されて裸の導体として露出され、 該裸の導体に折り返し形状のウレタン系エナメル被覆導線よりなる補強導線が縦 添えされて一緒に撚り合わされ、これら裸の導体と補強導線との撚線部が前記端 子金具に半田付け接続されていることを特徴とする。Further, in the present invention, at the terminal connecting portion of the coil having a structure in which the terminal wire of the coil formed of the imide resin-coated conductive wire is soldered to the terminal fitting, the connecting end of the terminal wire of the coil is provided. The insulating coating is removed to expose the part as a bare conductor, and a reinforcing conductor made of a folded urethane-based enamel-coated conductor is vertically attached to the bare conductor and twisted together to form a bare conductor and a reinforcing conductor. The stranded wire portion of is connected to the terminal fitting by soldering.
【００１７】 これらの考案で、補強導線の折り返し形状とは、補強導線をＵ字状に１回折り 返すか若しくは所定長さで互いに逆向きにＵ字状に複数回折り返した形状をいう 。In these inventions, the folded shape of the reinforcing conductor means a shape in which the reinforcing conductor is folded back in a U-shape once or folded back in a U-shape in a reverse direction with a predetermined length.

【００１９】[0019]
このようにコイルの端末線の接続端部でその絶縁被覆を除去して裸の導体を露 出させ、この裸の導体に折り返し形状の補強導線を縦添えして一緒に撚り合わせ 、これら裸の導体と補強導線との撚線部を端子金具に半田付け接続すると、コイ ルの端末線の接続端部での絶縁被覆の除去長さは短くてよく、コイルの端末線の 絶縁被覆の除去作業が簡単となる。 In this way, the insulating coating is removed at the connection end of the terminal wire of the coil to expose the bare conductor, and a folded-back reinforcing conductor is vertically attached to the bare conductor and twisted together. When the stranded wire portion of the conductor and the reinforcing conductor wire is connected to the terminal fitting by soldering, the removal length of the insulation coating at the connection end of the coil terminal wire may be short. Will be easier.
【００２０】 また、コイルの端末線の接続端部が１本の裸の導体でも、これに折り返し形状 の補強導線を縦添えして一緒に撚り合わせているので、機械的強度を向上させる ことができる。Further, even in the case of a bare conductor having a single connection end portion of the coil terminal wire, since a reinforcing conductor having a folded shape is vertically attached and twisted together, it is possible to improve mechanical strength. it can.
【００２１】 補強導線として裸の導体を使用すると、該補強導線の絶縁被覆の除去作業が不 要となる。また、裸の導体よりなる補強導線によれば、コイルの端末線の接続端 部としての裸の導体との撚線部が総て裸の導体で構成されているので、端子金具 との半田付け接続を良好に行うことができる。If a bare conductor is used as the reinforcing conductor, the work of removing the insulating coating of the reinforcing conductor becomes unnecessary. Also, according to the reinforcing conductor made of a bare conductor, since the stranded wire portion with the bare conductor as the connecting end of the coil terminal wire is composed entirely of the bare conductor, soldering with the terminal metal Good connection can be made.
【００２２】 また補強導線としてウレタン系エナメル被覆導線を使用すると、該補強導線の 絶縁被覆を除去しなくても半田付けをすることができる。Further, when a urethane-based enamel-coated conductor wire is used as the reinforcing conductor wire, soldering can be performed without removing the insulating coating of the reinforcing conductor wire.
【００２３】 またコイルをイミド系樹脂被覆導線で形成すると、コイルの使用温度を高める ことができる。イミド系樹脂被覆導線でもその絶縁被覆の除去区間は短いので、 例えばバーナで焼いても容易に絶縁被覆の除去作業を行うことができる。このよ うなイミド系樹脂被覆導線よりなるコイルの端末の裸の導体に、折り返し形状の ウレタン系エナメル被覆導線よりなる補強導線を縦添えしてもコイルの表面温度 は低くなっているので、該補強導線の絶縁被覆がコイルの熱で溶けるのを防止で きる。更に、補強導線としてウレタン系エナメル被覆導線を使用すると、該補強 導線の絶縁被覆を除去しなくても半田付けをすることができる。Further, when the coil is formed of the imide resin coated conductive wire, the operating temperature of the coil can be increased. Even in the case of the imide-based resin-coated conductor, the insulation coating removal section is short, so that the insulation coating removal work can be easily performed even if the imide-based resin coating conductor is burned with a burner, for example. Even if a reinforcing conductor made of a folded urethane enamel coated wire is vertically attached to the bare conductor at the end of the coil made of such an imide resin coated wire, the surface temperature of the coil is still low. It is possible to prevent the insulation coating of the conductor wire from being melted by the heat of the coil. Further, when a urethane-based enamel-coated conductor wire is used as the reinforcing conductor wire, soldering can be performed without removing the insulating coating of the reinforcing conductor wire.

There is.
【００２６】 該発電コイル３の端末線１の接続端部においては、その絶縁被覆１ｂがサンド ペーパー等で機械的に除去されて銅細線からなる裸の導体１ａが露出されている 。At the connection end of the terminal wire 1 of the power generating coil 3, the insulating coating 1b is mechanically removed by sandpaper or the like to expose the bare conductor 1a made of a thin copper wire.
【００２７】 この裸の導体１ａには、該裸の導体１ａと同じ外径か、或いはそれ以上の外径 の裸の銅線よりなる折り返し形状の補強導線７が図２（Ａ）に示すように縦添え されて、図２（Ｂ）に示すように一緒に撚り合わされ、これら裸の導体１ａと補 強導線７との撚線部２が図１に示すように端子金具４に半田８付け接続されてい る。本実施例の場合、補強導線７は１回の折りの折り返し形状となっている。As shown in FIG. 2A, the bare conductor 1a has a folded-back reinforcing conductor 7 made of a bare copper wire having an outer diameter equal to or larger than that of the bare conductor 1a. 2 and are twisted together as shown in FIG. 2B, and the stranded wire portion 2 of the bare conductor 1a and the reinforcing conductor 7 is soldered to the terminal fitting 4 as shown in FIG. It is connected. In the case of the present embodiment, the reinforcing conductive wire 7 has a folded shape of one folding.
【００２８】 本実施例の端子金具４は、第１の金具部４ａと、これに直交する向きに曲げら れて設けられている第２の金具部４ｂとでＬ字状に、銅板によって構成されてい る。第１の金具部４ａの図示しない孔には、撚線部２が通されて半田８付けで接 続されている。該第１の金具部４ａは発電コイル３の外周に、直接或いは絶縁層 を介して添わされ、絶縁テープ１８の巻き付けにより固定されている。The terminal fitting 4 of the present embodiment is formed of a copper plate in an L shape with a first fitting part 4 a and a second fitting part 4 b bent and provided in a direction orthogonal to the first fitting part 4 a. Has been done. The stranded wire portion 2 is passed through a hole (not shown) of the first metal fitting portion 4a and is connected by soldering 8. The first metal fitting portion 4a is attached to the outer periphery of the power generation coil 3 directly or via an insulating layer, and is fixed by winding an insulating tape 18.
【００２９】 第２の金具部４ｂには、その図示しない孔に口出線（出力線）９が通されて半 田１０付けで接続されている。A lead wire (output wire) 9 is passed through a hole (not shown) of the second metal fitting portion 4b, and is connected to the second metal fitting portion 4b.
【００３０】 このように発電コイル３の端末線１の接続端部でその絶縁被覆を除去して裸の 導体１ａを露出させ、この裸の導体１ａに折り返し形状の補強導線７を縦添えし て一緒に撚り合わせ、これら裸の導体１ａと補強導線７との撚線部２を端子金具 ４の第１の金具部４ａに半田８付け接続すると、発電コイル３の端末線１の接続 端部での絶縁被覆１ｂの除去長さは短くてよく、発電コイル３の端末線１の絶縁 被覆１ｂの除去作業が簡単となる。In this manner, the insulating coating is removed at the connection end portion of the terminal wire 1 of the generator coil 3 to expose the bare conductor 1a, and the folded conductor wire 7 is vertically attached to the bare conductor 1a. When they are twisted together and the stranded wire portion 2 of the bare conductor 1a and the reinforcing conductor 7 is connected by soldering 8 to the first metal fitting portion 4a of the terminal metal fitting 4, the connecting end portion of the terminal wire 1 of the generator coil 3 is connected.

【００３１】 また、発電コイル３の端末線１の接続端部が１本の裸の導体１ａでも、これに 補強導線７を縦添えして一緒に撚り合わせているので、機械的強度を向上させる ことができる。Further, even in the case of the bare conductor 1a having a single connecting end portion of the terminal wire 1 of the power generation coil 3, the reinforcing conductor wire 7 is vertically attached to the bare conductor 1a and twisted together, so that the mechanical strength is improved. be able to.

Further, according to the reinforcing conductor 7 made of a bare conductor, since the twisted wire portion 2 with the bare conductor 1a at the connecting end portion of the terminal wire 1 of the power generation coil 3 is entirely made of a bare conductor, The solder 8 connection with the first metal fitting portion 4a of the terminal metal fitting 4 can be satisfactorily performed.

【００３４】 このように補強導線７としてウレタン系エナメル被覆導線を使用すると、ウレ タン系エナメル被覆は加熱状態にある半田ごての温度で溶けるため、該補強導線 ７の絶縁被覆を除去しなくても半田付けをすることができる。When the urethane-based enamel-coated conductor is used as the reinforcing conductor 7 in this way, the urethane-based enamel coating melts at the temperature of the soldering iron in a heated state, so that the insulating coating of the reinforcing conductor 7 must be removed.

It is also possible to connect by soldering to the first metal fitting part 4a of No.4.
【００３６】 このように、発電コイル３をイミド系樹脂被覆導線で形成すると、該発電コイ ル３の使用温度を高めることができる。イミド系樹脂被覆導線でもその絶縁被覆 の除去区間は短いので、容易に絶縁被覆の除去作業を行うことができる。このよ うなイミド系樹脂被覆導線よりなる発電コイル３の端末線１の接続端部における 裸の導体１ａに、折り返し形状のウレタン系エナメル被覆導線よりなる補強導線 ７を縦添えしても、該発電コイル３の表面温度は低くなっているので、該補強導 線７の絶縁被覆が該発電コイル３の熱で溶けるのを防止できる。更に、補強導線 ７としてウレタン系エナメル被覆導線を使用すると、該補強導線７の絶縁被覆を 除去しなくても半田８付けをすることができる。As described above, when the power generating coil 3 is formed of the imide-based resin-coated conductive wire, the operating temperature of the power generating coil 3 can be increased. Even with an imide-based resin-coated conductor, the insulation coating removal section is short, so the insulation coating removal work can be performed easily. Even if a reinforcing conductor 7 made of a folded urethane-based enamel-coated conductor is vertically attached to the bare conductor 1a at the connecting end of the terminal wire 1 of the power generation coil 3 made of such an imide-based resin-coated conductor, Since the surface temperature of the coil 3 is low, it is possible to prevent the insulating coating of the reinforcing wire 7 from being melted by the heat of the magneto coil 3.

以上説明したように、本考案に係るコイルの端末接続部によれば、下記のよう な優れた効果を得ることができる。 As described above, according to the coil terminal connecting portion of the present invention, the following excellent effects can be obtained.
【００４３】 本考案では、コイルの端末線の接続端部でその絶縁被覆を除去して裸の導体を 露出させ、この裸の導体に折り返し形状の補強導線を縦添えして一緒に撚り合わ せ、これら裸の導体と補強導線との撚線部を端子金具に半田付け接続するので、 コイルの端末線の接続端部での絶縁被覆の除去長さは短くてよく、コイルの端末 線の絶縁被覆の除去作業が簡単となる利点がある。In the present invention, the insulating coating is removed at the connection end of the terminal wire of the coil to expose the bare conductor, and the reinforced conductor wire having a folded shape is vertically attached to the bare conductor and twisted together. Since the stranded wire portion of these bare conductor and reinforcing wire is connected by soldering to the terminal fitting, the removal length of the insulation coating at the connection end of the coil terminal wire can be short, and the insulation of the coil terminal wire can be reduced. There is an advantage that the work of removing the coating is simple.
【００４４】 また本考案では、コイルの端末線の接続端部が１本の裸の導体でも、これに補 強導線を縦添えして一緒に撚り合わせているので、機械的強度を向上させること ができる。Further, in the present invention, even if the connecting end of the terminal wire of the coil is a bare conductor, the reinforcing conductor is vertically attached to the conductor and twisted together, so that the mechanical strength is improved. You can
【００４５】 また本考案で、補強導線として裸の導体を使用すると、該補強導線の絶縁被覆 の除去作業が不要となる。また、裸の導体よりなる補強導線によれば、コイルの 端末線の接続端部としての裸の導体との撚線部が総て裸の導体で構成されている ので、端子金具との半田付け接続を良好に行うことができる。In the present invention, when a bare conductor is used as the reinforcing conductor, the work of removing the insulating coating of the reinforcing conductor is unnecessary. Also, according to the reinforcing conductor made of a bare conductor, since the twisted wire portion with the bare conductor as the connecting end of the terminal wire of the coil is composed entirely of the bare conductor, it is soldered to the terminal fitting. Good connection can be made.
【００４６】 また本考案で、補強導線としてウレタン系エナメル被覆導線を使用すると、該 補強導線の絶縁被覆を除去しなくても半田付けをすることができる。Further, in the present invention, when a urethane-based enamel-coated conductor wire is used as the reinforcing conductor wire, soldering can be performed without removing the insulating coating of the reinforcing conductor wire.
【００４７】 また本考案で、コイルをイミド系樹脂被覆導線で形成すると、コイルの使用温 度を高めることができる。イミド系樹脂被覆導線でもその絶縁被覆の除去区間は 短いので、容易に絶縁被覆の除去作業を行うことができる。このようなイミド系 樹脂被覆導線よりなるコイルの端末の裸の導体に、折り返し形状のウレタン系エ ナメル被覆導線よりなる補強導線を縦添えしてもコイルの表面温度は低くなって いるので、該補強導線の絶縁被覆がコイルの熱で溶けるのを防止できる。更に、 補強導線としてウレタン系エナメル被覆導線を使用すると、該補強導線の絶縁被 覆を除去しなくても半田付けをすることができる。Further, in the present invention, when the coil is formed of the imide resin-coated conductive wire, the operating temperature of the coil can be increased. Even with an imide-based resin-coated conductor, the insulation coating removal section is short, so the insulation coating removal work can be performed easily. Even if a reinforcing conductor made of a folded urethane-based enamel-coated conductor is vertically attached to the bare conductor at the end of the coil made of such an imide-based resin-coated conductor, the surface temperature of the coil is still low. It is possible to prevent the insulating coating of the reinforcing wire from being melted by the heat of the coil. Furthermore, when a urethane-based enamel-coated conductor is used as the reinforcing conductor, soldering can be performed without removing the insulating coating of the reinforcing conductor.
