Description

本発明は、モータの外形を小型化する技術に関する。   The present invention relates to a technique for reducing the outer shape of a motor.

図７は従来の２相ＰＭ型ステッピングモータの端子構造を示す斜視図である。   FIG. 7 is a perspective view showing a terminal structure of a conventional two-phase PM type stepping motor.

図７に示すように、コイルの各末端１０２ａ，１０２ｂが電気的に接続される一対の端子ピン１０３，１０４は、モータ回転軸１００を含む平面に対して垂直に、モータの外径から大きく突出するように端子保持部１０５に取り付けられている。端子ピン１０３，１０４は、コイルの末端１０２ａ，１０２ｂが巻線されて接続されるコイル接続部１０３ａ，１０４ａと、外部端子などに接続される外部接続部１０３ｂ、１０４ｂとを有する。端子ピン１０３，１０４及び端子保持部１０５は、コイルの各相ごとに設けられ、コイルはコイルボビンに巻線される（例えば、特許文献１参照）。   As shown in FIG. 7, the pair of terminal pins 103 and 104 to which the ends 102 a and 102 b of the coil are electrically connected project greatly from the outer diameter of the motor perpendicular to the plane including the motor rotation shaft 100. It is attached to the terminal holding part 105 so that it may do. The terminal pins 103 and 104 have coil connection portions 103a and 104a to which coil ends 102a and 102b are wound and connected, and external connection portions 103b and 104b connected to external terminals and the like. The terminal pins 103 and 104 and the terminal holding part 105 are provided for each phase of the coil, and the coil is wound around a coil bobbin (see, for example, Patent Document 1).

図８は、図７のモータの端子構造を改良したもので、（ａ）は正面図、（ｂ）は（ａ）をＸＺ平面から見た断面図である。コイル１０２が巻線されるコイルボビン１に設けられた端子保持部１０５に凹状の段差１０５ａを形成することによって、外部接続部１０３ｂ，１０４ｂに外部端子などを接続する際にコイルの末端１０２ａ，１０２ｂを破損するなどの弊害が起こらないように対処している（例えば、特許文献２参照）。   FIG. 8 shows an improvement of the terminal structure of the motor shown in FIG. 7, wherein (a) is a front view and (b) is a cross-sectional view of (a) as viewed from the XZ plane. By forming a concave step 105a in the terminal holding part 105 provided on the coil bobbin 1 around which the coil 102 is wound, when connecting an external terminal or the like to the external connection parts 103b and 104b, the coil ends 102a and 102b are connected. Countermeasures are taken so as not to cause damage such as damage (for example, see Patent Document 2).

図９に他の従来のモータの端子構造を示し、（ａ）は正面図、（ｂ）は（ａ）をＸＺ平面から見た断面図である。   FIG. 9 shows a terminal structure of another conventional motor, where (a) is a front view and (b) is a sectional view of (a) as viewed from the XZ plane.

図９に示すように、コイル１０２の末端が電気的に接続される端子ピン２０３，２０４は、その軸線がコイルの巻回軸線（Ｘ方向）に平行で、かつ巻回軸線を含む平面に対して平行になるように端子保持部２０５に取り付けられている。この例では、端子ピン２０３，２０４がモータの外径から大きく突出することはなくなるが、この構造を２相ＰＭ型ステッピングモータに適用する場合、各相の端子ピンをコイルの巻回軸線まわりに同じ角度に配置することができないので、外部端子との接続が煩雑になる（例えば、特許文献３参照）。
実開昭６１−５５４４９号公報 実開平２−８３６８１号公報 特開平６−３８４２６号公報 As shown in FIG. 9, the terminal pins 203 and 204 to which the ends of the coil 102 are electrically connected are parallel to the winding axis (X direction) of the coil and the plane including the winding axis. Are attached to the terminal holding portion 205 so as to be parallel to each other. In this example, the terminal pins 203 and 204 do not protrude greatly from the outer diameter of the motor. However, when this structure is applied to a two-phase PM type stepping motor, the terminal pins of each phase are arranged around the winding axis of the coil. Since it cannot arrange at the same angle, connection with an external terminal becomes complicated (for example, refer to patent documents 3).

また、好ましくは、前記端子ピンは、前記コイルの末端の一方が接続される第１のピン部と、前記コイルの末端の他方が接続される第２のピン部とが互いに絶縁されて前記コイルボビンに取り付けられ、当該第１及び第２のピン部が前記巻回軸線を含む平面に対して平行でかつ同軸に配置される。   Preferably, in the terminal pin, the first pin portion to which one end of the coil is connected and the second pin portion to which the other end of the coil is connected are insulated from each other so that the coil bobbin And the first and second pin portions are disposed parallel to and coaxially with a plane including the winding axis.

また、好ましくは、前記第１及び第２のピン部は、前記巻回軸線を含む平面に平行に伸びる水平部と、当該水平部の端部を曲げ加工して形成された当該平面に垂直に突出する鉛直部とを有し、前記水平部は、前記コイルボビンに一体的に形成された保持部に取り付けられる。   Preferably, the first and second pin portions include a horizontal portion extending parallel to a plane including the winding axis, and a perpendicular to the plane formed by bending an end portion of the horizontal portion. The horizontal portion is attached to a holding portion formed integrally with the coil bobbin.

尚、以下に説明する実施の形態は、本発明の実現手段としての一例であり、本発明は、その趣旨を逸脱しない範囲で下記実施形態を修正又は変形したものに適用可能である。   The embodiment described below is an example as means for realizing the present invention, and the present invention can be applied to a modified or modified embodiment described below without departing from the spirit of the present invention.

［第１の実施の形態］
図１は本発明をステッピングモータに適用して実施した例を示し、（ａ）は斜視図、（ｂ）は正面図、（ｃ）は平面図である。 [First Embodiment]
FIG. 1 shows an example in which the present invention is applied to a stepping motor, wherein (a) is a perspective view, (b) is a front view, and (c) is a plan view.

図１に示すように、本実施の形態の単相ＰＭ型ステッピングモータは、ハードディスクのヘッドシーク機構やＣＤ−ＲＯＭなどの補助記憶媒体のピックアップ機構を駆動するためのリードスクリューモータとして用いられ、中空円筒形状のコイルボビン１にはコイル２が巻線されている。コイルボビン１はコイル２の巻回軸線（Ｘ方向）方向に伸びる中央部１ｃと、両端部に拡径したフランジ部１ａ，１ｂを有し、例えば樹脂を素材として成形されている。コイル２は、一端部のフランジ部１ａからコイル２の巻回軸線に沿ってフランジ部１ｂに向けて巻線されており、その末端の一方は端子ピン３に、他方は端子ピン４にそれぞれ電気的に結線されている。端子ピン３，４はそれぞれＬ字状に曲折された形状とされ、フランジ部１ｂの外周部に一体的に形成された端子保持部５に貫通するように取り付けられる。   As shown in FIG. 1, the single-phase PM type stepping motor of this embodiment is used as a lead screw motor for driving a head seek mechanism of a hard disk and a pickup mechanism of an auxiliary storage medium such as a CD-ROM. A coil 2 is wound around a cylindrical coil bobbin 1. The coil bobbin 1 has a central portion 1c extending in the winding axis (X direction) direction of the coil 2, and flange portions 1a and 1b having diameters expanded at both ends, and is formed of, for example, resin. The coil 2 is wound from the flange portion 1a at one end along the winding axis of the coil 2 toward the flange portion 1b. One end of the coil 2 is electrically connected to the terminal pin 3 and the other is electrically connected to the terminal pin 4. Are connected. The terminal pins 3 and 4 are each bent into an L shape, and are attached so as to penetrate the terminal holding portion 5 formed integrally with the outer peripheral portion of the flange portion 1b.

なお、コイルボビン１の中空内部にはコイル２の巻回軸線を回転軸とするモータの出力軸のまわりに磁石が設けられた不図示の回転子が配置され、コイル２が通電により励磁されて回転子を回転させる。   In the hollow inside of the coil bobbin 1, a rotor (not shown) provided with a magnet around an output shaft of a motor whose rotation axis is the winding axis of the coil 2 is disposed, and the coil 2 is excited by energization to rotate. Rotate the child.

一対の端子ピン３，４は、その軸線がコイルの巻回軸線と交差し（Ｙ方向）、かつ当該巻回軸線を含む平面（ＸＹ平面）に対して平行になるように端子保持部５に取り付けられている。   The pair of terminal pins 3 and 4 are arranged on the terminal holding portion 5 so that the axis thereof intersects with the winding axis of the coil (Y direction) and is parallel to the plane including the winding axis (XY plane). It is attached.

また、一対の端子ピン３，４は、コイル２の末端の一方２ａが接続される第１のピン部３と、コイルの末端の他方２ｂが接続される第２のピン部４とが互いに端子保持部５により絶縁されて取り付けられ、当該第１及び第２のピン部３，４が巻回軸線を含む平面（ＸＹ）に対して平行に並列に配置される。   In addition, the pair of terminal pins 3 and 4 are connected to each other by the first pin portion 3 to which one end 2a of the coil 2 is connected and the second pin portion 4 to which the other end 2b of the coil is connected. The first and second pin portions 3, 4 are insulated and attached by the holding portion 5, and are arranged in parallel to the plane (XY) including the winding axis.

第１及び第２のピン部３，４は、上記巻回軸線を含む平面（ＸＹ平面）に平行にＹ方向に伸びる水平部３ａ，４ａと、当該水平部３ａ，４ａの端部を曲げ加工して形成された当該平面に垂直にＺ方向に突出する鉛直部３ｂ、４ｂとを有し、水平部３ａ，４ａが端子保持部５に取り付けられる。   The first and second pin portions 3 and 4 are formed by bending horizontal portions 3a and 4a extending in the Y direction in parallel to a plane (XY plane) including the winding axis, and ends of the horizontal portions 3a and 4a. The horizontal portions 3 a and 4 a are attached to the terminal holding portion 5. The vertical portions 3 b and 4 b protrude in the Z direction perpendicular to the plane formed as described above.

そして、端子保持部５を挟んで一方側に第１のピン部３の水平部３ａと第２のピン部４の鉛直部４ｂとが互いに隣接して配置されると共に、他方側に第１のピン部３の鉛直部３ｂと第２のピン部４の水平部４ａとが互いに隣接して配置される。また、各水平部３ａ，４ａにｈａコイル２の末端２ａ，２ｂが巻線されて接続され、各鉛直部３ｂ，４ｂにはコイル２への通電を可能にする外部端子などが接続される。   And the horizontal part 3a of the 1st pin part 3 and the vertical part 4b of the 2nd pin part 4 are arrange | positioned adjacent to each other on both sides of the terminal holding part 5, and the first side is on the other side. The vertical portion 3b of the pin portion 3 and the horizontal portion 4a of the second pin portion 4 are disposed adjacent to each other. Further, the ends 2a and 2b of the ha coil 2 are wound and connected to the horizontal portions 3a and 4a, and external terminals and the like that enable energization of the coil 2 are connected to the vertical portions 3b and 4b.

なお、端子保持部５を挟んで一方側に第１及び第２のピン部３，４の各水平部３ａ，４ａとを隣接させ、第１及び第２のピン部３，４の各鉛直部３ｂ、４ｂとを隣接して配置し、各水平部３ａ，４ａにコイル２の末端２ａ，２ｂを接続し、各鉛直部３ｂ、４ｂに外部端子を接続してもよい。   The horizontal portions 3a and 4a of the first and second pin portions 3 and 4 are adjacent to each other with the terminal holding portion 5 in between, and the vertical portions of the first and second pin portions 3 and 4 are adjacent to each other. 3b and 4b may be arranged adjacent to each other, the ends 2a and 2b of the coil 2 may be connected to the horizontal portions 3a and 4a, and external terminals may be connected to the vertical portions 3b and 4b.

また、端子ピン３，４における各水平部３ａ，４ａは、互いにコイル２の巻回軸線を含む平面（ＸＹ平面）に平行な同一平面上に配置されてコイル２の巻回軸線を含む平面（ＸＹ平面）に垂直なＺ方向の寸法が抑えられている。   Further, the horizontal portions 3a and 4a of the terminal pins 3 and 4 are arranged on the same plane parallel to the plane (XY plane) including the winding axis of the coil 2 and are planes including the winding axis of the coil 2 ( The dimension in the Z direction perpendicular to the (XY plane) is suppressed.

また、各鉛直部３ｂ、４ｂは、曲げ加工によって、その上端部が当該ＸＹ平面に平行な同一平面上に位置するように、略同じ長さで鉛直方向（Ｚ方向）に伸びているので、外部端子などとの接続が容易になる。   Moreover, each vertical part 3b, 4b extends in the vertical direction (Z direction) with substantially the same length so that its upper end part is located on the same plane parallel to the XY plane by bending. Easy connection with external terminals.

また、各水平部３ａ，４ａは、コイルボビン１の外径（モータの外径）と略同じ長さを有している。従って、各水平部３ａ，４ａがモータの外径から大きくはみ出すことなく、モータ全体の外形を小型化でき、省スペース化を図ることができる。   Each horizontal portion 3a, 4a has substantially the same length as the outer diameter of the coil bobbin 1 (motor outer diameter). Accordingly, the horizontal portions 3a and 4a do not protrude greatly from the outer diameter of the motor, and the outer shape of the entire motor can be reduced in size, thereby saving space.

また、端子ピン３，４を端子固定部５に貫通させて取り付けることよって、コイル２を接続する水平部３ａ，４ａと外部端子などに接続される鉛直部３ｂ、４ｂとを分離することができるので、コイル２の接続や外部端子との接続などの組立て作業を容易化することができる。   Further, by attaching the terminal pins 3 and 4 through the terminal fixing portion 5, it is possible to separate the horizontal portions 3a and 4a connecting the coil 2 from the vertical portions 3b and 4b connected to an external terminal or the like. Therefore, assembly operations such as connection of the coil 2 and connection to the external terminal can be facilitated.

［第２の実施の形態］
図２は、第２の実施の形態の端子ピンの構造を示す正面図（ａ）、平面図（ｂ）、ＸＺ平面から見た断面図（ｃ）である。また、図３は、第２の実施の形態の端子ピンの構造の変形例を示す正面図（ａ）、平面図（ｂ）、ＸＺ平面から見た側面図（ｃ）である。 [Second Embodiment]
FIG. 2 is a front view (a), a plan view (b), and a cross-sectional view (c) viewed from the XZ plane showing the structure of the terminal pin of the second embodiment. FIG. 3 is a front view (a), a plan view (b), and a side view (c) viewed from the XZ plane showing a modification of the structure of the terminal pin according to the second embodiment.

第１の実施の形態の各端子ピン３，４がＬ字状に曲折して形成されていたのに対して、第２の実施の形態の各端子ピン１３，１４は直線状に形成されている（鉛直部３ｂ、４ｂを削除した）点が異なっている。この第２の実施の形態では、外部端子に接続される端部１３ｂ，１４ｂが端子固定部５を挟んで互いに相反する方向に伸びているので外部端子との接続は若干煩雑となるものの、各端子ピン１３，１４はコイルボビン１の外径（モータの外径）と略同じ長さを有するので、第１の実施の形態と同様に、端子ピン１３，１４がモータの外径から大きくはみ出すことなく、モータ全体の外形を小型化でき、省スペース化を図ることができるという効果が得られる。   The terminal pins 3 and 4 of the first embodiment are bent in an L shape, whereas the terminal pins 13 and 14 of the second embodiment are formed in a straight line. (The vertical portions 3b and 4b are deleted). In the second embodiment, since the end portions 13b and 14b connected to the external terminal extend in directions opposite to each other with the terminal fixing portion 5 interposed therebetween, the connection with the external terminal is slightly complicated, Since the terminal pins 13 and 14 have substantially the same length as the outer diameter of the coil bobbin 1 (the outer diameter of the motor), the terminal pins 13 and 14 protrude greatly from the outer diameter of the motor as in the first embodiment. Thus, the outer shape of the entire motor can be reduced, and the space can be saved.

また、図３に示すように、端子ピン１３，１４におけるコイル接続部１３ａ，１４ａを端子固定部５の同じ側に配置し、端子固定部５にコイル２を各コイル接続部１３ａ，１４ｂに誘導するための切り欠き１５を形成することで、上述した外部端子との接続の煩雑さも解消できる。   Further, as shown in FIG. 3, the coil connecting portions 13a and 14a of the terminal pins 13 and 14 are arranged on the same side of the terminal fixing portion 5, and the coil 2 is guided to the terminal fixing portion 5 to the coil connecting portions 13a and 14b. By forming the notch 15 for this purpose, the above-described troublesome connection with the external terminal can be eliminated.

なお、第１の実施形態と同一の要素には同一の符号を付して説明を省略する。   In addition, the same code | symbol is attached | subjected to the element same as 1st Embodiment, and description is abbreviate | omitted.

［第３の実施の形態］
図４は、第３の実施の形態の端子ピンの構造を示す正面図（ａ）、（ａ）のＸＺ方向から見た断面図（ｂ）、第３の実施の形態の端子ピンの構造の変形例を示す正面図（ｃ）である。 [Third Embodiment]
FIG. 4 is a front view (a) showing the structure of the terminal pin of the third embodiment, a cross-sectional view (b) as viewed from the XZ direction of (a), and the structure of the terminal pin of the third embodiment. It is a front view (c) which shows a modification.

第３の実施の形態は、Ｌ字状の端子ピン２３，２４の水平部２３ａ，２４ａを互いに同一軸線上に配置した点が第１の実施の形態の構造と異なっている。この第３の実施の形態では、端子固定部２５のＸ方向のサイズをより小さくできるので、第１の実施の形態に比べて小型化及び省スペース化の効果が飛躍的に向上する。   The third embodiment is different from the structure of the first embodiment in that the horizontal portions 23a and 24a of the L-shaped terminal pins 23 and 24 are arranged on the same axis. In the third embodiment, since the size of the terminal fixing portion 25 in the X direction can be made smaller, the effect of downsizing and space saving can be dramatically improved as compared with the first embodiment.

また、第１の実施の形態と同様に、端子ピン２３，２４がモータの外径から大きくはみ出すことなく、モータ全体の外形を小型化でき、省スペース化を図ることができるという効果が得られる。   Further, similarly to the first embodiment, the terminal pins 23 and 24 do not protrude greatly from the outer diameter of the motor, so that the outer shape of the entire motor can be reduced, and the space can be saved. .

また、図４（ｃ）は、第３の実施の形態の端子ピンの構造の変形例として、直線状に形成された端子ピン３３，３４を同一軸線上に配置した例を示しているが、この変形例によっても同様の効果を得ることができる。   FIG. 4C shows an example in which the terminal pins 33 and 34 formed in a straight line are arranged on the same axis as a modification of the structure of the terminal pin of the third embodiment. Similar effects can be obtained by this modification.

なお、その他の第３の実施形態と同一の要素には同一の符号を付して説明を省略する。   In addition, the same code | symbol is attached | subjected to the element same as other 3rd Embodiment, and description is abbreviate | omitted.

［第４の実施の形態］
図５は、第４の実施の形態の端子ピンの構造を示す正面図（ａ）、（ａ）をＸＺ平面から見た断面図（ｂ）である。 [Fourth Embodiment]
FIG. 5 is a cross-sectional view (b) of the front view (a) and (a) showing the structure of the terminal pin of the fourth embodiment as seen from the XZ plane.

第４の実施の形態は、第２の実施の形態の直線状の端子ピン１３，１４を、ＸＹ平面に対して垂直方向に上下に配置した点が特徴となっている。この第４の実施の形態でも、第３の実施形態と同様に、端子固定部３５の巻回軸線（Ｘ方向）のサイズをより小さくできるので、第１の実施の形態に比べて小型化及び省スペース化の効果が飛躍的に向上する。   The fourth embodiment is characterized in that the linear terminal pins 13 and 14 of the second embodiment are arranged vertically in the direction perpendicular to the XY plane. Also in the fourth embodiment, since the size of the winding axis (X direction) of the terminal fixing portion 35 can be made smaller as in the third embodiment, the size and size can be reduced as compared with the first embodiment. The effect of space saving is dramatically improved.

［応用例］
図６は、第１の実施の形態の端子ピンの構造を２相ＰＭ型ステッピングモータに適用した例を示す斜視図である。 [Application example]
FIG. 6 is a perspective view showing an example in which the structure of the terminal pin of the first embodiment is applied to a two-phase PM type stepping motor.

図６に示すように、２相以上のコイルを有するモータでは、図１に示す一対の端子ピン３，４と端子固定部５との組み合わせをコイルの相数に対応する数だけ設ければよく、本例の場合には２相あるのでＸ方向に沿って２組設けてある。このようにコイルの相数が増加した場合でも、端子ピンをモータの外径から大きくはみ出すことなく配置でき、小型化及び省スペース化の要求を満たすことができる。   As shown in FIG. 6, in a motor having two or more phases of coils, the number of combinations of the pair of terminal pins 3 and 4 and the terminal fixing portion 5 shown in FIG. In this example, since there are two phases, two sets are provided along the X direction.
