以下、本発明を具体化した一実施形態を図面に従って説明する。
図１，２に本実施形態のリアクトル１０を示す。本実施形態のリアクトル１０では、ＵＵ型コア２０を用いている。ＵＵ型コア２０は、第１のコアとしてのＵ型コア３０と、第２のコアとしてのＵ型コア４０により構成されている。 DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
1 and 2 show a reactor 10 of the present embodiment. In the reactor 10 of this embodiment, the UU type core 20 is used. The UU type core 20 includes a U type core 30 as a first core and a U type core 40 as a second core.

リアクトル１０は、ＵＵ型コア２０（Ｕ型コア３０，４０）と、コイル５０，６０と、モールド用の樹脂７０を備えている。
Ｕ型コア３０は、断面が四角形状の棒状をなし、図１（ａ）に示すように平面視においてＵ字状をなしている。Ｕ型コア３０は、真直ぐにかつ平行に延びる一対の直線部３１，３２と、直線部３１，３２の一端同士をつなぐ連結部３３とからなる。Ｕ型コア３０は、直線部３１に端面３１ａを有するとともに直線部３２に端面３２ａを有している。同様に、Ｕ型コア４０も、断面が四角形状の棒状をなし、図１（ａ）に示すように平面視においてＵ字状をなしている。Ｕ型コア４０は、真直ぐにかつ平行に延びる一対の直線部４１，４２と、直線部４１，４２の一端同士をつなぐ連結部４３とからなる。Ｕ型コア４０は、直線部４１に端面４１ａを有するとともに直線部４２に端面４２ａを有している。そして、Ｕ型コア４０の端面４１ａがＵ型コア３０の端面３１ａと突き合わされるとともにＵ型コア４０の端面４２ａがＵ型コア３０の端面３２ａと突き合わされることになる。 The reactor 10 includes a UU type core 20 (U type cores 30 and 40), coils 50 and 60, and a molding resin 70.
The U-shaped core 30 has a rectangular bar shape in cross section, and has a U shape in plan view as shown in FIG. The U-shaped core 30 includes a pair of straight portions 31 and 32 that extend straight and in parallel, and a connecting portion 33 that connects one ends of the straight portions 31 and 32. The U-shaped core 30 has an end surface 31 a at the straight portion 31 and an end surface 32 a at the straight portion 32. Similarly, the U-shaped core 40 also has a square bar shape in cross section, and has a U shape in plan view as shown in FIG. The U-shaped core 40 includes a pair of straight portions 41 and 42 that extend straight and in parallel, and a connecting portion 43 that connects one ends of the straight portions 41 and 42. The U-shaped core 40 has an end face 41 a at the straight portion 41 and an end face 42 a at the straight portion 42. The end surface 41 a of the U-shaped core 40 is abutted with the end surface 31 a of the U-shaped core 30, and the end surface 42 a of the U-shaped core 40 is abutted with the end surface 32 a of the U-shaped core 30.

Ｕ型コア３０の直線部３２の端面３２ａには突起３５が形成されている。突起３５は、端面３２ａよりも幅が狭く、端面３２ａの中央部においてＵ型コア３０の高さ方向において全長にわたり延設されている。また、Ｕ型コア４０の直線部４１の端面４１ａには突起４５が形成されている。突起４５は、端面４１ａよりも幅が狭く、端面４１ａの中央部においてＵ型コア４０の高さ方向において全長にわたり延設されている。   A protrusion 35 is formed on the end surface 32 a of the straight portion 32 of the U-shaped core 30. The protrusion 35 is narrower than the end surface 32a and extends over the entire length in the height direction of the U-shaped core 30 at the center of the end surface 32a. Further, a protrusion 45 is formed on the end face 41 a of the straight portion 41 of the U-shaped core 40. The protrusion 45 is narrower than the end face 41a, and extends over the entire length in the height direction of the U-shaped core 40 at the center of the end face 41a.

Ｕ型コア３０の直線部３１の端面３１ａと、Ｕ型コア４０の直線部４１の端面４１ａに形成した突起４５とは密着（面接触）している。同様に、Ｕ型コア３０の直線部３２の端面３２ａに形成した突起３５と、Ｕ型コア４０の直線部４２の端面４２ａとは密着（面接触）している。   The end surface 31 a of the straight portion 31 of the U-shaped core 30 and the protrusion 45 formed on the end surface 41 a of the straight portion 41 of the U-shaped core 40 are in close contact (surface contact). Similarly, the projection 35 formed on the end surface 32a of the straight portion 32 of the U-shaped core 30 and the end surface 42a of the straight portion 42 of the U-shaped core 40 are in close contact (surface contact).

閉磁路を作るためのＵＵ型コア２０において、突起３５，４５によるギャップが形成されている。このとき、突起３５，４５は対称位置に配置されている。
Ｕ型コア３０の直線部３１およびＵ型コア４０の直線部４１の周囲には、四角環状をなすコイル５０が巻回されている。同様に、Ｕ型コア３０の直線部３２およびＵ型コア４０の直線部４２の周囲には、四角環状をなすコイル６０が巻回されている。このように、ＵＵ型コア２０（Ｕ型コア３０，４０）は、コイル巻回部としての直線部３１，３２，４１，４２を有し、環状をなすコイル５０，６０が、ＵＵ型コア２０の直線部（コイル巻回部）３１，３２，４１，４２の周囲に巻回されている。即ち、Ｕ型コア３０とＵ型コア４０の少なくとも一部の周囲にコイル５０，６０が巻回されている。 In the UU type core 20 for making a closed magnetic path, a gap is formed by the protrusions 35 and 45. At this time, the protrusions 35 and 45 are arranged at symmetrical positions.
A square-shaped coil 50 is wound around the straight portion 31 of the U-shaped core 30 and the straight portion 41 of the U-shaped core 40. Similarly, a square-shaped coil 60 is wound around the straight portion 32 of the U-shaped core 30 and the straight portion 42 of the U-shaped core 40. Thus, the UU type core 20 (U type cores 30 and 40) has straight portions 31, 32, 41 and 42 as coil winding portions, and the coils 50 and 60 forming an annular shape are UU type cores 20. Are wound around the linear portions (coil winding portions) 31, 32, 41, 42. That is, the coils 50 and 60 are wound around at least part of the U-shaped core 30 and the U-shaped core 40.

ＵＵ型コア２０（Ｕ型コア３０，４０）とコイル５０，６０とは、その外周部がモールド用の樹脂７０により封止されている。つまり、コア３０，４０の端面３２ａ，４１ａに突起３５，４５を形成し、突起３５，４５を介してコア３０，４０の端面３１ａ，３２ａ，４１ａ，４２ａを突き合わせるとともに、Ｕ型コア３０，４０とコイル５０，６０とを樹脂７０により一体的にモールドしている。   The outer peripheral portion of the UU type core 20 (U type cores 30 and 40) and the coils 50 and 60 are sealed with a resin 70 for molding. That is, the protrusions 35 and 45 are formed on the end faces 32a and 41a of the cores 30 and 40, and the end faces 31a, 32a, 41a and 42a of the cores 30 and 40 are abutted through the protrusions 35 and 45, and the U-shaped core 30, 40 and the coils 50 and 60 are integrally molded with a resin 70.

次に、リアクトルの製造工程について説明する。
まず、Ｕ型コア３０とＵ型コア４０とコイル５０とコイル６０を用意する。このとき、Ｕ型コア３０の突起３５は所定の突出量となるように調整しておく。同様に、Ｕ型コア４０の突起４５も所定の突出量となるように調整しておく。 Next, the manufacturing process of a reactor is demonstrated.
First, a U-shaped core 30, a U-shaped core 40, a coil 50, and a coil 60 are prepared. At this time, the protrusion 35 of the U-shaped core 30 is adjusted to have a predetermined protrusion amount. Similarly, the protrusion 45 of the U-shaped core 40 is also adjusted so as to have a predetermined protrusion amount.

そして、コイル５０の内方にＵ型コア３０の直線部３１を挿入するとともにコイル６０の内方にＵ型コア３０の直線部３２を挿入する。また、コイル５０の内方にＵ型コア４０の直線部４１を挿入するとともにコイル６０の内方にＵ型コア４０の直線部４２を挿入する。このとき、Ｕ型コア３０の端面３２ａおよびＵ型コア４０の端面４１ａに形成した突起３５，４５を介してＵ型コア３０の端面３１ａ，３２ａとＵ型コア４０の端面４１ａ，４２ａとを突き合わせる。   Then, the straight portion 31 of the U-shaped core 30 is inserted inside the coil 50 and the straight portion 32 of the U-shaped core 30 is inserted inside the coil 60. Further, the straight portion 41 of the U-shaped core 40 is inserted inside the coil 50 and the straight portion 42 of the U-shaped core 40 is inserted inside the coil 60. At this time, the end surfaces 31a and 32a of the U-shaped core 30 and the end surfaces 41a and 42a of the U-shaped core 40 are brought into contact with each other via protrusions 35 and 45 formed on the end surface 32a of the U-shaped core 30 and the end surface 41a of the U-shaped core 40. The

引き続き、この状態でＵ型コア３０とＵ型コア４０とコイル５０，６０とを樹脂７０により一体的にモールドする。この樹脂モールドする際において、Ｕ型コア３０，４０とコイル５０，６０の位置合わせを金型により行う。また、突起３５，４５の突出量が調整されていることにより図１（ｃ）に示すギャップ長Ｇを所定値にすることができる。   Subsequently, the U-shaped core 30, the U-shaped core 40, and the coils 50 and 60 are integrally molded with the resin 70 in this state. When the resin molding is performed, the U-shaped cores 30 and 40 and the coils 50 and 60 are aligned by a mold. Moreover, the gap length G shown in FIG.1 (c) can be made into predetermined value by adjusting the protrusion amount of protrusion 35,45.

突起３５，４５によりギャップを設けることにより、ギャップ板が不要となり、ギャップ板の組立、仮固定等についても不要となる。このようにして、コアにおいて接着によらないでギャップを有するリアクトルを構成することができる。   By providing the gap with the projections 35 and 45, the gap plate is not required, and the gap plate is not required to be assembled or temporarily fixed. In this way, a reactor having a gap can be configured without depending on adhesion in the core.

また、Ｕ型コア３０，４０同士が樹脂７０にて固定されるため、リアクトル全体の剛性が向上してＮＶ（Ｎｏｉｓｅ ａｎｄ Ｖｉｂｒａｔｉｏｎ）を向上させることができる。   Further, since the U-shaped cores 30 and 40 are fixed to each other by the resin 70, the rigidity of the entire reactor can be improved and NV (Noise and Vibration) can be improved.

以上のごとく本実施形態によれば、以下のような効果を得ることができる。
（１）突起３５，４５によるギャップを設けることによりギャップ板を用いることなくコアにギャップを形成することができる。また、ギャップ板が不要となり、組立や仮固定等も不要となり、リアクトルのギャップ板の接着工程を廃止して突起３５，４５によるギャップ付きのリアクトルとすることができる。また、接着剤の材料費を削減できるとともに接着工程を無くすことにより製造コストの低減を図ることができる。さらに、樹脂７０により一体的にモールドされることにより剛性を向上することができる。 As described above, according to the present embodiment, the following effects can be obtained.
(1) By providing a gap by the protrusions 35 and 45, a gap can be formed in the core without using a gap plate. Further, the gap plate is not required, and assembly and temporary fixing are not required, and the reactor gap plate bonding process can be abolished and a reactor with a gap by the protrusions 35 and 45 can be obtained. In addition, the material cost of the adhesive can be reduced, and the manufacturing cost can be reduced by eliminating the bonding step. Furthermore, rigidity can be improved by being molded integrally with the resin 70.

（２）コア３０およびコア４０は、いずれもＵ型コアであるので、ギャップの周囲にコイル５０，６０を配置する上で好ましい。
（３）コア３０およびコア４０はいずれもＵ型コアであり、さらに、コア３０における両端面３１ａ，３２ａのうちの端面３２ａに突起３５を形成するとともにコア４０における両端面４１ａ，４２ａのうちの端面４１ａに突起４５を形成したので、二つのＵ型コア３０，４０として同じ形状とすることができる。これにより、部品管理が容易となる。 (2) Since both the core 30 and the core 40 are U-shaped cores, it is preferable in arranging the coils 50 and 60 around the gap.
(3) Each of the core 30 and the core 40 is a U-shaped core, and further, a projection 35 is formed on the end face 32a of the both end faces 31a and 32a of the core 30 and the end of the both end faces 41a and 42a of the core 40 Since the protrusion 45 is formed on the end face 41a, the two U-shaped cores 30 and 40 can have the same shape. Thereby, parts management becomes easy.

実施形態は前記に限定されるものではなく、例えば、次のように具体化してもよい。
・図１，２に代わる構成として図３，４に示す構成としてもよい。図３，４において、Ｕ型コア４０の直線部４２の端面４２ａには突起４６が形成されている。突起４６は、端面４２ａよりも幅が狭く、端面４２ａの中央部においてＵ型コア４０の高さ方向において全長にわたり延設されている。また、図１，２と同様に、Ｕ型コア４０の直線部４１の端面４１ａには突起４５が形成されている。突起４５は、端面４１ａよりも幅が狭く、端面４１ａの中央部においてＵ型コア４０の高さ方向において全長にわたり延設されている。 The embodiment is not limited to the above, and may be embodied as follows, for example.
A configuration shown in FIGS. 3 and 4 may be used instead of FIGS. 3 and 4, a protrusion 46 is formed on the end face 42 a of the straight portion 42 of the U-shaped core 40. The protrusion 46 is narrower than the end face 42a and extends over the entire length in the height direction of the U-shaped core 40 at the center of the end face 42a. 1 and 2, a protrusion 45 is formed on the end surface 41a of the straight portion 41 of the U-shaped core 40. The protrusion 45 is narrower than the end face 41a, and extends over the entire length in the height direction of the U-shaped core 40 at the center of the end face 41a.

そして、Ｕ型コア３０の直線部３１の端面３１ａと、Ｕ型コア４０の直線部４１の端面４１ａに形成した突起４５とは密着（面接触）している。また、Ｕ型コア３０の直線部３２の端面３２ａと、Ｕ型コア４０の直線部４２の端面４２ａに形成した突起４６とは密着（面接触）している。このようにＵ型コア４０の端面４１ａ，４２ａに突起４５，４６を形成し、突起４５，４６を介してＵ型コア３０，４０の端面３１ａ，３２ａ，４１ａ，４２ａを突き合わせるとともに、Ｕ型コア３０，４０とコイル５０，６０とを樹脂７０により一体的にモールドする。   The end surface 31 a of the straight portion 31 of the U-shaped core 30 and the protrusion 45 formed on the end surface 41 a of the straight portion 41 of the U-shaped core 40 are in close contact (surface contact). Further, the end surface 32 a of the straight portion 32 of the U-shaped core 30 and the protrusion 46 formed on the end surface 42 a of the straight portion 42 of the U-shaped core 40 are in close contact (surface contact). Thus, the protrusions 45 and 46 are formed on the end faces 41a and 42a of the U-shaped core 40, and the end faces 31a, 32a, 41a and 42a of the U-shaped cores 30 and 40 are abutted through the protrusions 45 and 46, and the U-shaped The cores 30 and 40 and the coils 50 and 60 are integrally molded with the resin 70.

・コアの端面に形成する突起について、例えば図２等に示すように突起４５は端面４１ａの中央部においてＵ型コア４０の高さ方向の全長にわたり延設されていた。これに代わり、突起はＵ型コア（４０）の高さ方向の全長にわたり延びていなくてもよい。   Regarding the protrusion formed on the end face of the core, for example, as shown in FIG. 2 and the like, the protrusion 45 extends over the entire length in the height direction of the U-shaped core 40 at the center of the end face 41a. Alternatively, the protrusion may not extend over the entire length of the U-shaped core (40).

・また、例えば図２等に示すように突起４５は一つの端面４１ａに１つ設けたが、これに代わり、一つの端面に複数個の突起を形成してもよい。
・また、突起の形状は問わない。 Further, for example, as shown in FIG. 2 and the like, one protrusion 45 is provided on one end face 41a, but instead, a plurality of protrusions may be formed on one end face.
-The shape of the protrusion is not limited.
