Description

本発明は、各種電子機器に使用される電源用トランス、信号用トランス非絶縁あるいは絶縁トランス等のトランスに用いられるボビンとトランスとボビンへの巻線方法に関する。   The present invention relates to a bobbin used for a transformer such as a power transformer, a signal transformer non-insulated or an insulating transformer used in various electronic devices, and a winding method around the transformer and the bobbin.

事務機器や家電製品等に組み込まれるトランスに用いられるボビンとして、従来より、巻線を施す巻胴部を円形、角形、長円形等の形状に形成している。このような従来のボビンとして特許文献１〜４に記載のものがある。   2. Description of the Related Art Conventionally, as a bobbin used in a transformer incorporated in office equipment, home appliances, etc., a winding body portion to be wound is formed in a circular shape, a rectangular shape, an oval shape, or the like. Examples of such conventional bobbins are disclosed in Patent Documents 1 to 4.

特開２０００−３２３３３３号公報JP 2000-323333 A 実公平３−５３４６２号公報Japanese Utility Model Publication No. 3-53462 特表２００４−５１４２８２号公報JP-T-2004-514282 実開平５−８７９１８号公報Japanese Utility Model Publication No. 5-87918

従来のボビンの巻胴部の内空部および外周部の巻芯方向に垂直な断面の形状は円形、角形、長円形等であり、例えば角形の場合、ある辺に対して垂直をなす第一の中心線に対してその中心線により分割された両側の形状が対称形をなすと共に、前記第一の中心線に垂直な第二の中心線により分割された両側の形状も対称形をなす。円形や長円形の場合も互いに垂直な２本の中心線に対して対称をなす形状である。このため、巻線機のチャックの巻軸に一次側端子、二次側端子を有するトランス用ボビンを装着して巻線を施す場合、一次側端子、二次側端子の位置が分かりにくく、ボビンを巻軸の中心に対して１８０度反転させて装着する間違いが生じるおそれがある。また、ボビンの取付け方向の間違いから、一次側端子に二次側巻線をからげたり、二次側端子に一次側巻線をからげたりする間違いが生じ易くなる。   The shape of the cross section perpendicular to the core direction of the inner hollow portion and the outer peripheral portion of the bobbin winding body of the conventional bobbin is a circle, a square, an oval, etc. For example, in the case of a square, the first perpendicular to a certain side The shape of both sides divided by the center line is symmetrical with respect to the center line, and the shape of both sides divided by the second center line perpendicular to the first center line is also symmetrical. In the case of a circular shape or an oval shape, the shape is symmetrical with respect to two center lines perpendicular to each other. For this reason, when a transformer bobbin having a primary side terminal and a secondary side terminal is mounted on the winding axis of the chuck of the winding machine and winding is performed, the positions of the primary side terminal and the secondary side terminal are difficult to understand. There is a possibility that an error occurs when the lens is reversed 180 degrees with respect to the center of the winding axis. In addition, an error in bobbin attachment is likely to cause an error in tangling the secondary winding to the primary terminal or tangling the primary winding to the secondary terminal.

さらに、前記ボビンの方向が分かり難いため、捺印、測定、基板への装着等の工程において方向を間違えて作業を行なうおそれがある。   Further, since the direction of the bobbin is difficult to understand, there is a risk of performing the work in the wrong direction in processes such as marking, measurement, and mounting on the substrate.

本発明は、上記問題点に鑑み、巻線作業等のコイル部品の製造工程においてボビンの装着方向の判別がしやすく、もって作業の効率が向上すると共に、歩留まりの向上が図れる構成のトランス用のボビンとそのボビンを用いたトランスとボビンへの巻線方法を提供することを目的とする。   In view of the above-described problems, the present invention makes it easy to determine the mounting direction of a bobbin in a coil component manufacturing process such as winding work, thereby improving work efficiency and improving the yield. It is an object of the present invention to provide a bobbin, a transformer using the bobbin, and a winding method around the bobbin.

前記巻胴部の内空部の巻芯方向に垂直な断面の形状がほぼ卵形であり、かつ前記巻胴部の肉厚が全周にわたり均一である

また、本発明のトランスは、巻線を施す筒状の巻胴部の両端に鍔部を有し、これらの鍔部の一方に、前記巻胴部が間に介在するように２つの端子台を設けると共に、前記巻胴部の内空部にその内空部の断面形状に合致する磁心の中足が挿着されるボビンを有する縦型トランスであって、
前記ボビンとして請求項１に記載のボビンを有する
ことを特徴とする。 Further, the transformer of the present invention has two terminal blocks such that the cylindrical winding drum portion on which the winding is wound has flanges at both ends, and the winding drum portion is interposed between one of these flanges. A vertical transformer having a bobbin into which a middle leg of a magnetic core matching the cross-sectional shape of the inner space portion is inserted into the inner space portion of the winding body portion ,
The bobbin according to claim 1 as the bobbin.
It is characterized by that.

また、本発明のトランスは、巻線を施す筒状の巻胴部の両端に鍔部を有し、これらの鍔部にそれぞれ端子台を設けてこれらの端子台により基板への取付け面を形成すると共に、前記巻胴部の内空部にその内空部の断面形状に合致する磁心の中足が挿着されるボビンを有する横型トランスであって、
前記ボビンとして請求項１に記載のボビンを有する
ことを特徴とする。 In addition, the transformer of the present invention has flanges on both ends of a cylindrical winding body portion on which windings are provided, and terminal blocks are provided on these flange portions, respectively, and a mounting surface to the substrate is formed by these terminal blocks. And a horizontal transformer having a bobbin into which the middle leg of the magnetic core matching the cross-sectional shape of the inner space portion is inserted into the inner space portion of the winding body portion ,

It is characterized by that.

本発明のボビンへの巻線方法は、巻線を施す筒状の巻胴部を有し、前記巻胴部の内空部にその内空部の断面形状に合致する磁心の中足が挿着されるトランス用のボビンへの巻線方法であって、

前記巻軸を回転させることにより前記ボビンも回転させて前記巻胴部に巻線する
ことを特徴とする。 The bobbin winding method according to the present invention has a cylindrical winding body portion for winding, and the inner leg of the winding body portion is inserted with the middle leg of the magnetic core matching the cross-sectional shape of the inner space portion. A winding method for a transformer bobbin to be worn,
The shape of the cross section perpendicular to the core direction of the inner hollow portion of the bobbin body of the bobbin is an oval shape, and the wall thickness of the bobbin body is uniform over the entire circumference,
The cross-sectional shape of the winding axis of the winding machine for winding the bobbin is a shape that matches the cross-sectional shape of the inner space,
Fitting the inner space of the winding body to the winding shaft,
The winding is wound around the primary side terminal or the secondary side terminal of the terminal block of the bobbin,
By rotating the winding shaft, the bobbin is also rotated and wound around the winding body portion.

本発明のボビンは、巻胴部の内空部の巻芯方向に垂直な断面の形状がほぼ卵形であり、かつ前記巻胴部の肉厚が全周にわたり均一であるように構成したので、巻線作業において、ボビンの回転方向の位置の判別が容易であり、巻線機の巻軸へのセットが容易となり、作業効率が向上する。 Since the bobbin of the present invention is configured such that the shape of the cross section perpendicular to the core direction of the inner hollow portion of the winding drum portion is substantially oval, and the thickness of the winding drum portion is uniform over the entire circumference . In the winding work, the position of the bobbin in the rotating direction can be easily determined, and the winding machine can be easily set on the winding shaft, thereby improving work efficiency.

また、巻軸にボビンの内空部に合致する卵形の断面形状のものを用いることにより、ボビンの端子台の向きは巻軸の向きに合致しなければボビンのセットができないから、巻軸にボビンをセットする際にボビンの向きが自動的に決まり、セットの間違いの発生が回避できる。 Also, by using an oval cross-sectional shape that matches the inner space of the bobbin, the bobbin cannot be set unless the bobbin terminal block direction matches the direction of the reel. When setting the bobbin on the bobbin, the direction of the bobbin is automatically determined, and the occurrence of a setting error can be avoided.

また、巻軸の回転方向の初期設定位置が一定であるために端子台および一次側端子、二次側端子の回転方向の初期設定位置が自動的に一定となり、巻線端末をからげる対象の端子を間違うことも回避することができる。また同様の理由により、捺印、測定、基板への取付けにおいても作業ミスを回避することができる。そしてこれらのことから、トランスの製造における歩留まりを向上させることができる。   In addition, since the initial setting position in the rotation direction of the winding axis is constant, the initial setting position in the rotation direction of the terminal block, primary side terminal, and secondary side terminal is automatically constant, and the winding end is tangled. It is possible to avoid mistaken terminals. For the same reason, it is possible to avoid work mistakes in stamping, measuring, and mounting on a substrate. And from these things, the yield in manufacture of a transformer can be improved.

図１、図２、図３はそれぞれ本発明のボビンの一実施の形態を示す正面図、側面図、背面図であり、図４は図３のＥ−Ｅ断面図である。この実施の形態はボビン１の巻線を施す巻胴部２の両端に形成された鍔部３、４のうち、一方の鍔部３にのみ一次側端子５および二次側端子６を取付ける端子台７、８を設けた縦型トランス用ボビンについて示している。 1, 2, and 3 are a front view, a side view, and a rear view, respectively, showing an embodiment of the bobbin of the present invention, and FIG. 4 is a cross-sectional view taken along line EE in FIG. 3. This embodiment is a terminal for attaching the primary side terminal 5 and the secondary side terminal 6 to only one of the flange portions 3 and 4 formed at both ends of the winding drum portion 2 for winding the bobbin 1. A vertical transformer bobbin provided with bases 7 and 8 is shown.

図４において、Ｏは巻胴部２の内空部の縦横の中心点を示す。ここで巻胴部２の内空部の巻芯に垂直方向の断面における端子台７、８の対向方向の中心線をＹ軸とし、前記断面における前記端子台の対向方向に垂直をなす方向の中心線をＸ軸とする。このとき、この実施の形態においては、前記断面の形状を、前記Ｘ軸により分割された内空部の一方の領域１０の断面と他方の領域１１の断面とが非対称形をなす形状に形成する。本実施の形態においては、この巻胴部２の内空部（外周部も同様）の断面形状をほぼ卵形に形成している。   In FIG. 4, O represents the vertical and horizontal center points of the inner space of the winding drum section 2. Here, the center line of the opposing direction of the terminal blocks 7 and 8 in the cross section in the vertical direction to the core of the inner space of the winding drum section 2 is the Y axis, and the direction perpendicular to the opposing direction of the terminal block in the cross section is The center line is the X axis. At this time, in this embodiment, the shape of the cross section is formed so that the cross section of one region 10 of the inner space divided by the X axis and the cross section of the other region 11 form an asymmetric shape. . In the present embodiment, the cross-sectional shape of the inner hollow portion (same for the outer peripheral portion) of the winding drum portion 2 is formed in an oval shape.

図５は前記ボビンを用いて構成した縦型トランスの一例を示す正面図、図６はその側面図である。このトランスはフェライト製の２つのＥ型コア１２、１２を用いたものである。各コア１２は、それぞれ端面部１３と、その端面部１３の両端より突出して設けた一対の外足部１４、１４と、一対の外足部１４、１４の間に端面部１３より突出して設けた中足部１５とを有する。ここで、中足部１５は、前記巻胴部１の内空部の断面形状に合致する非対称形に形成する。 FIG. 5 is a front view showing an example of a vertical transformer constructed using the bobbin, and FIG. 6 is a side view thereof. This transformer uses two E-type cores 12 and 12 made of ferrite. Each core 12 is provided to project from the end surface portion 13 between the end surface portion 13, a pair of outer foot portions 14, 14 provided projecting from both ends of the end surface portion 13, and the pair of outer foot portions 14, 14. And a midfoot 15. Here, the middle foot portion 15 is formed in an asymmetric shape that matches the cross-sectional shape of the inner space of the winding drum portion 1.

１６は前記巻胴部２に巻かれ、かつ外周にテープを巻いた巻線であり、一次巻線と二次巻線とが含まれる。このように巻胴部２に巻線１６を施したボビン１の巻胴部２に対し、一対のコア１２、１２の各中足部１５を挿入すると共に、外足部１４、１４は、一次側端子用端子台７と二次側端子用端子台８との間に嵌めてコア１２、１２をボビン１に組み合わせる。そして組み合わせたコア１２、１２の外周にテープ（図示せず）を貼り付けて固定するか、あるいは接着等により固定する。   Reference numeral 16 denotes a winding wound around the winding body 2 and having a tape wound around its outer periphery, and includes a primary winding and a secondary winding. Thus, while inserting each middle leg part 15 of a pair of cores 12 and 12 with respect to the winding drum part 2 of the bobbin 1 which provided winding 16 to the winding drum part 2, outer leg parts 14 and 14 are primary. The cores 12 and 12 are combined with the bobbin 1 by being fitted between the terminal block 7 for side terminals and the terminal block 8 for secondary terminals. Then, a tape (not shown) is affixed to the outer periphery of the combined cores 12 and 12 or fixed by adhesion or the like.

図７は巻線機２０の巻軸２１に前記ボビン１をセットして巻線を施す作業状態を示す側面図、図８は図７のＦ−Ｆ断面図である。これらの図に示すように、巻軸２１はその断面形状がボビン１の巻胴部２の内空部に合致する形状に形成する。この巻線機２０を用いて巻線作業を行なう場合、予め回転方向の初期設定位置が決められている巻軸２１にボビン１の巻胴部２を嵌合し、一次側端子５または二次側端子６に巻線をからげ、巻軸２１を回転させて巻胴部２に巻線を施す。このような巻線工程は、トランスで巻線する本数分必要となる複数の工程である。この複数の巻線工程において、巻軸２１の回転方向の初期設定位置は同一に設定する場合と異ならせる場合とがある。   FIG. 7 is a side view showing a working state in which the bobbin 1 is set on the winding shaft 21 of the winding machine 20 and winding is performed, and FIG. 8 is a sectional view taken along line FF in FIG. As shown in these drawings, the winding shaft 21 is formed so that its cross-sectional shape matches the inner space of the winding body 2 of the bobbin 1. When the winding work is performed using the winding machine 20, the winding body portion 2 of the bobbin 1 is fitted to the winding shaft 21 whose initial setting position in the rotation direction is determined in advance, and the primary side terminal 5 or the secondary side The winding is wound on the side terminal 6 and the winding shaft 21 is rotated to wind the winding on the winding drum section 2. Such a winding process is a plurality of processes required for the number of windings by the transformer. In the plurality of winding processes, the initial setting position in the rotation direction of the winding shaft 21 may be set differently.

このような巻線作業を行なう場合、巻胴部２の外周部がＸ軸を挟んで非対称形をなすように卵形に形成したので、巻線作業において、ボビン１の回転方向の位置の目視による判別が容易である。このため巻軸２１へのボビン１のセットが容易となり、作業効率が向上する。 When performing such a winding operation, the outer peripheral portion of the winding drum portion 2 is formed in an oval shape so as to form an asymmetric shape with the X-axis interposed therebetween. Therefore, in the winding operation, the position of the bobbin 1 in the rotation direction is visually checked. Is easy to distinguish. For this reason, the bobbin 1 can be easily set on the winding shaft 21 and the working efficiency is improved.

また、本発明のようにボビン１の巻胴部２の内空部および巻軸２１をＸ軸を挟んで非対称形となるように形成すれば、ボビン１の巻胴部２の向きは巻軸２１の向きに合致しなければボビンのセットができないから、巻軸２１にボビン１をセットする際にボビン１の向きが自動的に決まり、セットの間違いの発生が回避できる。   Further, if the inner space of the winding drum portion 2 of the bobbin 1 and the winding shaft 21 are formed so as to be asymmetric with respect to the X axis as in the present invention, the direction of the winding drum portion 2 of the bobbin 1 is the winding shaft. Since the bobbin cannot be set unless the direction of the bobbin 21 is matched, the direction of the bobbin 1 is automatically determined when the bobbin 1 is set on the winding shaft 21, and the occurrence of a setting error can be avoided.

また、巻軸２１の回転方向の初期設定位置が一定であるため、端子台７、８および一次側端子５、二次側端子６の回転方向の初期設定位置が一定となるので、巻線端末をからげる対象端子を間違うことも回避できる。捺印、測定、基板への取付けにおいても同様に作業ミスを回避することができる。また、その結果、トランスの製造における歩留まりを向上させることができる。   Further, since the initial setting position in the rotation direction of the winding shaft 21 is constant, the initial setting positions in the rotation direction of the terminal blocks 7, 8 and the primary side terminal 5 and the secondary side terminal 6 are constant. It is also possible to avoid making mistakes in the target terminals that make a mistake. Similarly, work errors can be avoided in marking, measurement, and mounting on a substrate. As a result, the yield in the manufacture of the transformer can be improved.

なお、図４の実施の形態においては、巻胴部２の内空部は、そのＹ軸方向が広幅で、Ｘ軸方向を狭幅に設定しているが、このＸ軸、Ｙ軸方向の幅は等しいかあるいはＹ軸方向の幅が狭く、Ｘ幅方向が広い構造としてもよい。また、巻胴部２の内空部や外周部は、Ｘ軸により分割された２つの領域を非対称形とする卵形ではなく、Ｙ軸で分割された２つの領域を非対称形とする卵形にしてもよい。 In the embodiment shown in FIG. 4, the inner space of the winding drum section 2 has a wide Y-axis direction and a narrow X-axis direction. The widths may be the same or the width in the Y-axis direction is narrow and the X-width direction is wide. Further, the hollow portion and the outer peripheral portion of the winding body 2, rather than oval and asymmetric two areas divided by the X-axis, oval to asymmetrical divided two regions in the Y-axis It may be.

図９は本発明の他の実施の形態であり、この実施の形態は、ほぼ卵形をなす巻胴部２ＦのＹ軸を巻胴部２Ｆの断面の長手方向に設定し、そのＹ軸を端子台７、８の対向方向に対して傾斜させて形成したものである。 FIG. 9 shows another embodiment of the present invention. In this embodiment, the Y-axis of the winding drum portion 2F that is substantially oval is set in the longitudinal direction of the cross-section of the winding drum portion 2F, and the Y-axis is set. The terminal blocks 7 and 8 are formed to be inclined with respect to the facing direction.

The bobbin 23 is used for a horizontal transformer. The bobbin 23 is provided with a primary side terminal block 27 and a secondary side terminal block 28 on the flange portions 25 and 26 at both ends of the winding body portion 24, respectively, thereby forming a mounting surface 29 on a substrate (not shown). is there.

In the bobbin 23, with respect to a cross section perpendicular to the winding core direction of the inner hollow portion of the winding body portion 24, a center line perpendicular to the mounting surface 29 in the cross section is a Y axis. A center line parallel to the mounting surface 29 in the cross section is taken as the X axis. At this time, the shape of the cross section of the inner hollow portion of the winding drum portion 24 is asymmetrical between the cross section of one region 30 of the inner hollow portion of the winding drum portion 24 divided by the X axis and the cross section of the other region 31. It is formed into a shape to make.
