特開２００６−１７９６５４号公報JP 2006-179654 A

しかしながら、このものの場合、巻き付けられた導線の端部とターミナルとを接合させるために、接合部を先端側から半田槽に浸漬すると、半田の液面により導線が接合部に対して滑って押し上げられてしまい、導線とターミナルとの電気的な接続不良が発生し、また、接合部を半田槽から抜き出すと、半田の力により導線が接合部に対して滑って引き下げられてしまい、ターミナルから導線が外れてしまうという問題点があった。   However, in this case, in order to join the end of the wound conductive wire and the terminal, if the joint is immersed in the solder bath from the front end side, the conductive wire is slid and pushed up against the joint by the solder liquid level. As a result, a poor electrical connection between the conductor and the terminal occurs, and when the joint is pulled out of the solder bath, the conductor is slid and pulled down with respect to the joint due to the force of the solder. There was a problem that it would come off.

この発明は、上述のような問題点を解決することを課題とするものであって、その目的は、接合部がロウ材に浸漬される際に、ロウ材により導線が接合部に対して軸線方向に所定の範囲を超えて移動することを防止して、導線とターミナルとの電気的な接続不良の発生を低減し、また、ターミナルから導線が外れてしまうことを防ぐことができるコイル装置を提供するものである。   An object of the present invention is to solve the above-described problems. The purpose of the present invention is to provide an axis line with respect to the joint by the brazing material when the joint is immersed in the brazing material. A coil device capable of preventing movement beyond a predetermined range in the direction, reducing the occurrence of poor electrical connection between the conductor and the terminal, and preventing the conductor from being disconnected from the terminal It is to provide.

この発明に係るコイル装置は、ボビンと、前記ボビンに巻回された導線と、前記ボビンに設けられ、前記導線の端部が巻き付けられて前記導線と電気的に接続される、断面円形の線材からなるターミナルとを備え、前記ターミナルは、前記導線の端部が巻き付けられた領域の中で、先端側であって溶融したロウ材に浸漬されることにより前記導線と接合される接合部と前記接合部を除いた非接合部とを有したコイル装置において、前記接合部には、前記ロウ材に浸漬される際に、前記接合部に巻き付けられた前記導線の端部が前記ターミナルの軸線方向に移動するのを防止する第１の移動防止手段が設けられ、前記第１の移動防止手段は、前記線材が押しつぶされて一部が径方向に突出した偏平形状で間隔をおいて形成された複数の当接部であり、前記導線の端部は、隣り合う前記当接部の間から巻き付けが開始され、前記隣り合う前記当接部の一方の前記当接部にも巻き付けられている。

The coil device according to the present invention includes a bobbin, a conducting wire wound around the bobbin, a wire rod provided on the bobbin, and having an end portion of the conducting wire wound around and electrically connected to the conducting wire. A terminal composed of a joint portion joined to the lead wire by being immersed in a molten brazing material on the tip side in a region where the end portion of the lead wire is wound, and the terminal In the coil device having a non-joined portion excluding the joined portion, the end portion of the conducting wire wound around the joined portion is immersed in the brazing material in the joined portion in the axial direction of the terminal The first movement preventing means is provided , and the first movement preventing means is formed in a flat shape and spaced apart with a part protruding in the radial direction by the wire rod being crushed. With multiple abutments Ri, end of the lead is the wound from between the abutting portion adjacent the start, are wound in one of the contact portion of the contact portion where the adjacent.

この発明に係るコイル装置によれば、接合部がロウ材に浸漬される際に、接合部の第１の移動防止手段が、ロウ材により導線が接合部に対して軸線方向に所定の範囲を超えて移動することを防止するので、導線とターミナルとの電気的な接続不良の発生を低減し、また、ターミナルから導線が外れてしまうことを防ぐことができる。   According to the coil device of the present invention, when the joining portion is immersed in the brazing material, the first movement preventing means of the joining portion causes the conductive wire to have a predetermined range in the axial direction with respect to the joining portion by the brazing material. Since it is prevented from moving beyond, the occurrence of poor electrical connection between the conductor and the terminal can be reduced, and the conductor can be prevented from coming off from the terminal.

以下、この発明の各実施の形態を図に基づいて説明するが、各図において、同一または相当の部材、部位については、同一符号を付して説明する。

Embodiment 1 FIG.
1A is a plan view of the coil device according to this embodiment, FIG. 1B is a front view of the coil device of FIG. 1A, and FIG. 1C is the coil device of FIG. 2A is a front view showing the terminal 3 around which the conducting wire 2 of FIG. 1A is wound, FIG. 2B is a side view showing the terminal 3 of FIG. (C) is a side view which shows the terminal 3 of FIG.2 (b).
The coil device according to this embodiment includes a cylindrical bobbin 1, a conductive wire 2 wound around the bobbin 1, and a terminal 3 made of a wire fixed to the bobbin 1.
The end of the conducting wire 2 is wound around the distal end side of the terminal 3, and is electrically connected to the terminal 3 and fixed to the terminal 3 by solder which is a brazing material.

ターミナル３は、導線２が巻き付けられた領域の中で、先端側であって半田に浸漬されることにより導線２と接合される接合部３ａと、接合部３ａを除く非接合部３ｂとを有している。
接合部３ａには、半田に浸漬される際に、巻き付けられた導線２の端部が所定の範囲を超えて接合部３ａの軸線方向に移動するのを防止する第１の移動防止手段４が形成されている。 The terminal 3 has a joint portion 3a which is joined to the lead wire 2 by being immersed in the solder on the tip side in a region where the lead wire 2 is wound, and a non-joint portion 3b excluding the joint portion 3a. is doing.
The joint 3a has first movement preventing means 4 for preventing the end of the wound conductor 2 from moving in the axial direction of the joint 3a beyond a predetermined range when immersed in the solder. Is formed.

第１の移動防止手段４は、接合部３ａの先端側に形成された当接部５ａと、この当接部５ａより非接合部３ｂ側に間隔をおいて形成された当接部５ｂとから構成されている。
なお、第１の移動防止手段４の当接部の数は、これに限らない。
当接部５ａおよび当接部５ｂのそれぞれは、当接部５ａと当接部５ｂとの間の接合部３ａに巻き付けられた導線２の端部と軸線方向に当接可能となっている。
当接部５ａおよび当接部５ｂのそれぞれは、押しつぶされて一部が径方向に突出した偏平形状となっており、また、摩擦により導線２が切断されないようにエッジのない形状となっている。 The first movement preventing means 4 includes a contact portion 5a formed on the distal end side of the joint portion 3a and a contact portion 5b formed at a distance from the contact portion 5a toward the non-joint portion 3b. It is configured.
The number of contact portions of the first movement preventing means 4 is not limited to this.
Each of the contact part 5a and the contact part 5b can contact the end part of the conducting wire 2 wound around the joint part 3a between the contact part 5a and the contact part 5b in the axial direction.
Each of the contact portion 5a and the contact portion 5b has a flat shape that is crushed and partially protrudes in the radial direction, and has a shape without an edge so that the conductor 2 is not cut by friction. .

導線２は、当接部５ａと当接部５ｂとの間に密に巻き付けられ、連続して当接部５ｂに一周巻き付けられて、さらに非接合部３ｂに粗く巻き付けられている。
非接合部３ｂに巻き付けられた導線２は、連続してボビン１に巻回されている。 The conducting wire 2 is tightly wound between the contact portion 5a and the contact portion 5b, continuously wound around the contact portion 5b, and then roughly wound around the non-joint portion 3b.
The conducting wire 2 wound around the non-joining portion 3b is continuously wound around the bobbin 1.

次に、この実施の形態に係るコイル装置の導線２が巻き付けられたターミナル３を半田に浸漬するときの様子について説明する。
導線２が巻き付けられたターミナル３を先端側から、溶融した半田が溜められた槽に浸漬すると、半田の液面からの力により、巻き付けられた導線２が接合部３ａに対して滑り、所定の範囲だけ当接部５ｂ側に導線２が移動する。
しかしながら、巻き付けられた導線２が当接部５ｂと当接することにより、当接部５ｂより非接合部３ｂ側への導線２の移動が防止されるので、導線２とターミナル３との間に十分半田が浸漬されて、導線２とターミナル３との電気的な接続不良の発生を低減させることができ、また、導線２とターミナル３とを固定することができる。 Next, the state when the terminal 3 around which the conducting wire 2 of the coil device according to this embodiment is wound is immersed in solder will be described.
When the terminal 3 around which the conducting wire 2 is wound is immersed in a bath in which molten solder is accumulated from the tip side, the wound conducting wire 2 slides with respect to the joint portion 3a due to the force from the liquid level of the solder. The conductor 2 moves to the contact part 5b side by the range.
However, since the wound conducting wire 2 abuts against the abutting portion 5b, the movement of the conducting wire 2 from the abutting portion 5b toward the non-joining portion 3b is prevented, so that it is sufficient between the conducting wire 2 and the terminal 3. It is possible to reduce the occurrence of poor electrical connection between the conductor 2 and the terminal 3 by immersing the solder, and the conductor 2 and the terminal 3 can be fixed.

次に、半田の槽からターミナル３の先端を引き抜くと、半田の粘性による力により、導線２が接合部３ａに対して滑り、当接部５ａ側に導線２が所定の範囲だけ移動する。
しかしながら、導線２が当接部５ａと当接することにより、当接部５ａより先端側への導線２の移動が防止されるので、導線２がターミナル３から外れてしまうことを防ぐことができる。 Next, when the tip of the terminal 3 is pulled out from the solder bath, the conductive wire 2 slides with respect to the joint portion 3a due to the force of the solder viscosity, and the conductive wire 2 moves toward the contact portion 5a by a predetermined range.
However, since the lead wire 2 is in contact with the contact portion 5a, the lead wire 2 is prevented from moving from the contact portion 5a toward the distal end side, so that the lead wire 2 can be prevented from being detached from the terminal 3.

この実施の形態のコイル装置によれば、接合部３ａに巻き付けられた導線２が所定の範囲を超えてターミナル３の軸線方向に移動するのを防止する第１の移動防止手段４が接合部３ａに形成されているので、導線２の端部が巻き付けられたターミナル３の接合部３ａを溶融した半田に浸漬する際に、導線２が所定の範囲を超えて軸線方向に移動することが防止されて、導線２とターミナル３との電気的な接続不良の発生を低減し、また、ターミナル３から導線２が外れてしまうことを防ぐことができる。   According to the coil device of this embodiment, the first movement preventing means 4 for preventing the lead 2 wound around the joint 3a from moving in the axial direction of the terminal 3 beyond a predetermined range is provided in the joint 3a. Therefore, when the joining portion 3a of the terminal 3 around which the end portion of the conducting wire 2 is wound is immersed in molten solder, the conducting wire 2 is prevented from moving in the axial direction beyond a predetermined range. Thus, the occurrence of poor electrical connection between the conductor 2 and the terminal 3 can be reduced, and the conductor 2 can be prevented from being detached from the terminal 3.

また、第１の移動防止手段４は、接合部３ａに巻き付けられた導線２と軸線方向に当接可能な当接部５ａおよび当接部５ｂであるので、簡単な構成で導線２の所定の範囲を超えた軸線方向の移動を防止することができる。   Further, since the first movement preventing means 4 is the contact portion 5a and the contact portion 5b that can contact the conductor 2 wound around the joint portion 3a in the axial direction, a predetermined configuration of the conductor 2 can be achieved with a simple configuration. Movement in the axial direction beyond the range can be prevented.

第２の移動防止手段６は、非接合部３ｂの反接合部３ａ側に形成された当接部７から構成されている。
なお、第２の移動防止手段６の数は、これに限らない。
当接部７は、非接合部３ｂに巻き付けられた導線２が軸線方向に沿って、当接部７より反先端側に移動することを防止している。
当接部７は、押しつぶされて一部が径方向に突出した偏平形状となっており、また、摩擦により導線２が切断されないようにエッジのない形状となっている。
非接合部３ｂの当接部７と当接部５ｂとの間を屈曲させても、ターミナル３に巻き付けられた導線２が所定の範囲を超えて移動しないので、コイル装置が配置されるスペースに合わせてターミナル３を自由に変形させることができる。

The number of the second movement preventing means 6 is not limited to this.
The contact portion 7 prevents the lead wire 2 wound around the non-joined portion 3b from moving from the contact portion 7 to the opposite end side along the axial direction.
The contact portion 7 has a flat shape that is crushed and partially protrudes in the radial direction, and has no edge so that the conductor 2 is not cut by friction.
Even if the contact portion 7 and the contact portion 5b of the non-joining portion 3b are bent, the conductor 2 wound around the terminal 3 does not move beyond a predetermined range, so that the coil device is disposed in the space. In addition, the terminal 3 can be freely deformed.

この実施の形態に係るコイル装置によれば、非接合部３ｂに巻き付けられた導線２が所定の範囲を超えて軸線方向に移動することを防止する第２の移動防止手段６が非接合部３ｂに形成されているので、非接合部３ｂに巻き付けられた導線２が所定の範囲を超えて軸線方向に移動して、図示しない他の部品と接触することを防ぐことができる。
その結果、他の部品との接触により導線２が劣化してしまうことを抑制することができる。
また、非接合部３ｂの当接部７と当接部５ｂを変形させても導線２が所定の範囲を超えて移動しないので、ターミナル３を自由に変形させて、コイル装置のレイアウト性を向上させることができる。 According to the coil device according to this embodiment, the second movement preventing means 6 for preventing the conducting wire 2 wound around the non-joining portion 3b from moving in the axial direction beyond a predetermined range is provided with the non-joining portion 3b. Therefore, it is possible to prevent the conductive wire 2 wound around the non-joining portion 3b from moving in the axial direction beyond a predetermined range and coming into contact with other parts not shown.
As a result, it can suppress that the conducting wire 2 deteriorates by contact with another component.
Moreover, even if the contact part 7 and the contact part 5b of the non-joining part 3b are deformed, the lead wire 2 does not move beyond a predetermined range, so the terminal 3 can be freely deformed to improve the layout of the coil device. Can be made.
