Description

本発明は、大電流や高周波でも好適に使用できるチョークコイルや他のコイル部品として用いられるインダクタ用コイル構造及びインダクタに関する。   The present invention relates to a coil structure for an inductor and an inductor used as a choke coil and other coil components that can be suitably used even at high currents and high frequencies.

例えば、チョークコイルとして用いられるインダクタ用コイルとして、従来、図８（ａ）（ｂ）に示す平角コイルが知られている。この平角コイル１１は、帯状導電板からなる平角銅線１２を巻線して平面的なコイル部１３を形成し、コイル部１３の両端部に実装端子１４を形成したものである。   For example, a rectangular coil shown in FIGS. 8A and 8B is conventionally known as an inductor coil used as a choke coil. The flat coil 11 is formed by winding a flat copper wire 12 made of a strip-shaped conductive plate to form a flat coil portion 13 and mounting terminals 14 at both ends of the coil portion 13.

前記平角コイル１１は、図９に示すように、フェライトコアからなる磁性体のリベットコア１５とフェライトコアからなる磁性体のポットコア１６とからなるコア材１７によって埋設されており、実装端子１４は、折曲加工及び半田メッキを施してコア材１７の両端部における下面に露出して設けられている。 As shown in FIG. 9, the rectangular coil 11 is embedded with a core material 17 composed of a magnetic rivet core 15 made of a ferrite core and a magnetic pot core 16 made of a ferrite core. Bending and solder plating are performed so as to be exposed on the lower surface at both ends of the core material 17.

また、高周波トランスや高周波リアクタ等の電気素子に使用する連続折曲コイルにおいて、千鳥状に交互に反転する同一形状・連続波形の箔形導体が所定の折り返し部分から毎回特定角度ずれた方向に折り返して環状の連続巻きコイルとして形成した高周波トランス及び高周波リアクタが知られている（例えば、特許文献１参照。）。 Also, in continuous bending coils used for electrical elements such as high-frequency transformers and high-frequency reactors, foil-shaped conductors with the same shape and continuous waveform that are alternately reversed in a staggered manner are folded back in a direction deviated by a specific angle each time from a predetermined folded portion. A high-frequency transformer and a high-frequency reactor formed as an annular continuous winding coil are known (for example, see Patent Document 1).

また、平面状に配置した金属平板からなる複数のリング部において、リング連接部で連接された互いに隣接するリング部の中心を結ぶ中心線とによって形成される角度と、端子部と接続されたリング部の中心線と前記リング部の中心から前記端子部を形成した端部に向かって延長した延長線との角度の和を１８０度にしたコイル部品が知られている（例えば、特許文献２参照。）。
特開平９−２７５０２３号公報 特開２００４−１１１４５７号公報 Also, in a plurality of ring portions made of metal flat plates arranged in a planar shape, an angle formed by a center line connecting the centers of adjacent ring portions connected by the ring connecting portion and a ring connected to the terminal portion A coil component is known in which the sum of the angles of the center line of the part and the extension line extending from the center of the ring part toward the end part forming the terminal part is 180 degrees (see, for example, Patent Document 2) .)

Difficult, causing increased processing costs.

特許文献１は、千鳥状に交互に反転する同一形状・連続波形の箔形導体が所定の折り返し部分から毎回特定角度ずれた方向に折り返して環状の連続巻きコイルを形成しているため、折り目部の方向が一定せず、折り目部が僅かにずれても環状のコイル部がずれるため、加工が困難で、加工コストアップの原因である。   In Patent Document 1, since the foil-shaped conductors having the same shape and continuous waveform that are alternately reversed in a staggered manner are folded back in a direction deviated by a specific angle from a predetermined folded portion each time, an annular continuous winding coil is formed. The direction of is not constant, and even if the crease part is slightly displaced, the annular coil part is displaced, which makes machining difficult and causes an increase in machining cost.

特許文献２は、平面状に配置した複数のリング部をリング連接部で連接し、このリング連接部に折り目部を形成しているが、折り目部の方向が一定せず、折り目部が僅かにずれても環状のコイル部がずれるため、特許文献１と同様に、加工が困難で、加工コストアップの原因である。 In Patent Document 2, a plurality of ring portions arranged in a plane are connected by a ring connecting portion, and a crease portion is formed in the ring connecting portion, but the direction of the fold portion is not constant, and the crease portion is slightly Even if they are displaced, the annular coil portion is displaced, so that processing is difficult and causes an increase in processing costs, as in Patent Document 1.

It is possible to form an annular coil part by alternately repeating valley folds and mountain folds at the crease part to overlap the arcuate part, and the bending direction is constant, making the processing easy and reducing costs. An object is to provide a coil structure for an inductor and an inductor.

図１〜図４は第１の実施形態を示し、図１〜図３は１．５Ｔ用のインダクタ用コイルの製造工程を示し、図４はインダクタの斜視図である。図１に示す、符号２１は１枚の銅板を打抜き加工によって形成した薄肉の帯状導電板であり、Ｓは帯状導電板２１の長手方向に沿う中心線である。帯状導電板２１には中心線Ｓを基準とし、帯状導電板２１の一端側から他端側に複数の円弧状部２２ａ，２２ｂ，２２ｃが平面的に千鳥状に設けられている。これら円弧状部２２ａ，２２ｂ，２２ｃは同一形状の半円状であり、円弧状部２２ａと２２ｂとは連結部２３ａによって一体に連結され、円弧状部２２ｂと２２ｃとは連結部２３ｂによって一体に連結されてコイル形成部材２４が構成されている。   1 to 4 show a first embodiment, FIGS. 1 to 3 show a manufacturing process of an inductor coil for 1.5T, and FIG. 4 is a perspective view of the inductor. A reference numeral 21 shown in FIG. 1 is a thin strip-shaped conductive plate formed by punching one copper plate, and S is a center line along the longitudinal direction of the strip-shaped conductive plate 21. The strip-shaped conductive plate 21 is provided with a plurality of arc-shaped portions 22 a, 22 b, and 22 c in a zigzag shape on a plane from one end side to the other end side of the strip-shaped conductive plate 21 with the center line S as a reference. These arc-shaped portions 22a, 22b, and 22c are semicircular in the same shape, and the arc-shaped portions 22a and 22b are integrally connected by a connecting portion 23a, and the arc-shaped portions 22b and 22c are integrally connected by a connecting portion 23b. The coil forming member 24 is configured by being connected.

連結部２３ａ，２３ｂは円弧状部２２ａ，２２ｂ，２２ｃと同一幅で、中心線Ｓの延長方向に直線状であるとともに、連結部２３ａと２３ｂは同一長さに形成されている。さらに、コイル形成部材２４の連結部２３ａと２３ｂの長手方向の中間部には中心線Ｓと直交する方向に第１の折り目部２５ａと第２の折り目部２５ｂが形成されている。また、コイル形成部材２４の長手方向の両端部には中心線Ｓの延長方向に一体に実装端子２６が設けられ、これら実装端子２６は連結部２３ａ，２３ｂより僅かに幅広く形成されている。 The connecting portions 23a and 23b have the same width as the arc-shaped portions 22a, 22b, and 22c, are linear in the extending direction of the center line S, and the connecting portions 23a and 23b are formed to have the same length. Furthermore, a first fold portion 25a and a second fold portion 25b are formed in a direction perpendicular to the center line S at the intermediate portion in the longitudinal direction of the coupling portions 23a and 23b of the coil forming member 24. In addition, mounting terminals 26 are integrally provided in both ends of the coil forming member 24 in the extending direction of the center line S, and these mounting terminals 26 are formed slightly wider than the connecting portions 23a and 23b.

このように構成されたコイル形成部材２４を、第１の折り目部２５ａで谷折りすると、連結部２３ａで二つ折りされ、円弧状部２２ａと２２ｂとが中心線Ｓを挟んで向かい合い円環状のコイル部２７が形成される。次に、第２の折り目部２５ｂで山折りすると、連結部２３ｂで二つ折りされ、円弧状部２２ｂと２２ｃとが中心線Ｓを挟んで向かい合い円環状のコイル部２８が形成される。そして、円弧状部２２ｃが円弧状部２２ａの上面に重なり合う。従って、コイル部２７と２８とが同心的に重なり合い、このコイル形成部材２４の両端部には実装端子２６がコイル部２７と２８から突出して形成され、図２及び図３に示すようなインダクタ用コイル２９が完成する。 When the coil forming member 24 configured in this way is valley-folded at the first fold portion 25a, the coil-forming member 24 is folded in two at the connecting portion 23a, and the arc-shaped portions 22a and 22b face each other across the center line S, and the annular coil A portion 27 is formed.

Furthermore, first fold portions 45a to sixth fold portions 45f are formed in the direction perpendicular to the center line S at intermediate portions in the longitudinal direction of the connecting portions 43a to 43f of the coil forming member 44. Moreover, the terminal part 46 is integrally provided in the extension direction of the center line S in the both ends of the longitudinal direction of the coil formation member 44, and these terminal parts 46 are formed a little wider than the connection parts 43a-43f.

A portion 47a is formed. Next, when the second fold part 45b is folded in a mountain, the connecting part 43b is folded in half, and the arcuate parts 42b and 42c face each other across the center line S to form an annular coil part 47b. Similarly, when the third fold portion 45c is valley-folded, it is folded in two at the connecting portion 43c, and the arc-shaped portions 42c and 42d face each other across the center line S to form an annular coil portion 47c. Next, when the fourth fold portion 45d is mountain-folded, it is folded in two at the connecting portion 43d, and the arc-shaped portions 42d and 42e face each other across the center line S to form an annular coil portion 47d.
