【産業上の利用分野】[Industrial applications]

本考案は、導線が巻回されるコイルのコア構造に関する。 The present invention relates to a core structure of a coil around which a conductive wire is wound.

【0002】[0002]

【従来の技術】[Prior art]

従来より、導線を巻回して構成されるコイルの巻き枠又は磁芯(以下コアと称 する)は、図3乃至4に示すごとき形状に形成されている。 Conventionally, a winding frame or a magnetic core (hereinafter referred to as a core) of a coil formed by winding a conductive wire has a shape as shown in FIGS.

【0003】 図3に示すものは、円柱状の巻線部2の両端に巻線位置を規制する円盤状のフ ランジ3,3が形成されたものであり、図4に示すものは、巻線部4が断面矩形 に、フランジ5,5がその巻線部4にあわせて矩形平面に形成されたものである 。このようなコアの成形は、成形性の良い素材では一体成形も可能であるが、フ ェライトの粉末を用いて粉末冶金によって形成する場合等成形性の悪い場合には 、図3のものは円柱から回転切削によって、図4のものは四角柱からカッター又 は砥石車を用いて各面と平行に四面を切削又は研削によって削り出して形成され る。The one shown in FIG. 3 is one in which disk-shaped flanges 3 for restricting the winding position are formed at both ends of a columnar winding part 2, and the one shown in FIG. The wire portion 4 has a rectangular cross section, and the flanges 5 and 5 are formed in a rectangular plane so as to match the winding portion 4. Molding of such a core can be performed integrally with a material having good moldability, but in the case of poor moldability such as when powder metallurgy is used using powder of ferrite, the core of FIG. 4 is formed by rotary cutting, and the one shown in FIG. 4 is formed by cutting or grinding four faces in parallel with each face using a cutter or a grinding wheel from a square pole.

【0004】 上記のごとく形成されたコアには、巻線装置によってその巻線部2,4に導線 が所定の回数巻回されてコイルが構成される。巻線装置は、コアの一方のフラン ジをチャッキング手段で把持して巻線作業を行うが、この巻線装置へのコアの供 給は供給装置(パーツフィーダー)によって行われる。In the core formed as described above, a winding is wound around the winding portions 2 and 4 by a winding device to form a coil. The winding device grips one flange of the core by the chucking means to perform the winding work, and the supply of the core to the winding device is performed by the supply device (part feeder).

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、上記従来形状のコアは、図中一点鎖線で示す巻線部2,4の中 心軸を中心として巻線部2,4の外周に巻線が施されるものであり、当然のこと ながら方向性を有する。このため、供給装置はその方向性のあるコアを正しい姿 勢で巻線装置に供給する必要がある。その結果、供給装置の構造が複雑化すると ともに、高い精度で構成しなければならない。又、コア自体も、供給装置がその 方向性を正しく判別することができ、しかも供給装置の通路内で引っ掛かって詰 まりを生じたりすることのないように、その外形の寸法精度を所定の公差内にお さめなければならない。つまり、フランジ3,5等のコイルの性能とは直接関係 のない外形部分でも、製造工程側の要因によって高精度に形成しなけらばならず 、極めて不合理であってこれがコストダウンの障害となっている。 However, the core of the above-mentioned conventional shape is wound around the outer periphery of the winding portions 2 and 4 centering on the center axis of the winding portions 2 and 4 shown by the dashed line in the figure, which is natural. While having directionality. For this reason, the feeding device must feed the directional core to the winding device in the correct posture. As a result, the structure of the feeding device becomes complicated and must be constructed with high accuracy. In addition, the core itself can accurately determine its directionality, and the dimensional accuracy of its outer shape must be within a predetermined tolerance so that the core does not get caught in the passage of the feeder and become clogged. I have to keep it inside. In other words, the external parts that are not directly related to the coil performance, such as the flanges 3 and 5, must be formed with high precision due to factors in the manufacturing process, which is extremely irrational, which is an obstacle to cost reduction. Has become.

【0006】 本考案は、上記のごとき事情に基づいてなされたものであり、その目的は、方 向性の判別を不要として製造工程側の装置の構造の簡素化と性能上必要のない部 分の寸法精度の緩和を可能とし、コストの低減と生産性の向上とを可能とするコ イルコア構造を提供することにある。The present invention has been made based on the above circumstances, and an object thereof is to simplify the structure of a device on the manufacturing process side and to eliminate a part that is not necessary in terms of performance, because direction determination is unnecessary. Another object of the present invention is to provide a coil core structure that can reduce the dimensional accuracy of, reduce costs, and improve productivity.

【課題を解決するための手段】[Means for Solving the Problems]

上記目的達成のため、本考案に係るコイルコア構造は、導線が巻回されるコイ ルのコアであって、立方体状の本体の三面が交わる八箇所の頂部のそれぞれに巻 線規制凸部が突設されるとともに、該巻線規制凸部同士の間に形成される溝部が 巻線部とされ、六面すべてが等しい形状に形成されているものである。 In order to achieve the above object, the coil core structure according to the present invention is a coil core around which a conductive wire is wound, and a winding regulation convex portion is projected at each of the eight apexes where the three faces of the cubic body intersect. The groove portion formed between the winding regulation convex portions is a winding portion and is formed in the same shape on all six sides.

【作用】[Action]

上記コイルコア構造では、六面全ての形状が等しいために方向性がなく、各面 の中心を通る三本の軸線の何れを中心としても、巻線規制凸部同士によって挟ま れた巻線部に導線を巻回することができる。 In the above coil core structure, there is no directivity because the shapes of all six sides are the same, and any of the three axes passing through the center of each side is the center of the winding part sandwiched by the winding restriction protrusions. The conductor wire can be wound.

【実施例】【Example】

以下、本考案の実施例についてを添付図面を参照して説明する。 図1は、本考案に係るコイルコア構造を適用したコイルコアの一実施例の斜視 図である。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of an embodiment of a coil core to which a coil core structure according to the present invention is applied.

【0010】 図示のコイルコア1は、コア本体10が立方体状に形成され、その立方体状の 本体の外面三面が交わる八箇所の頂部のそれぞれに巻線規制凸部20が突設され ている。In the illustrated coil core 1, a core body 10 is formed in a cubic shape, and winding regulating protrusions 20 are provided at each of eight apexes where three outer surfaces of the cubic body intersect.

【0011】 巻線規制凸部20は、立方体を、その頂部をコア本体の頂部に対応させるとと もに、その各面を対応するコア本体の面と平行な状態として、コア本体10の中 心に向けて当該コア本体10内に所定量埋没させたような形状でコア本体10に 設けられている。これらの巻線規制凸部20は、コア本体10の面と垂直な方向 から見ると、図2に示すように正方形に見え、その頂部がコア本体10の頂部と 一致した状態から当該頂部の成す角(90°)を二等分する線を外側に延長した 方向に沿って所定量平行移動した状態となっている。つまり、巻線規制凸部20 は、当該巻線規制凸部20が突設されるコア本体10の三面の何れの面に対して も等しい形状(本実施例では正方形)を占有し、しかも、その各面は対応するコ ア本体10の外面から等しい高さを有している。これは、全ての巻線規制凸部2 0について全く同様である。The winding regulation convex portion 20 is formed in the core body 10 by making the top of the cube correspond to the top of the core body and keep each surface parallel to the corresponding surface of the core body. It is provided in the core body 10 in such a shape as to be buried in the core body 10 by a predetermined amount toward the heart. When viewed from a direction perpendicular to the surface of the core body 10, the winding regulation convex portions 20 look like a square as shown in FIG. 2, and the apex is formed from the state where the apex of the convex portion 20 coincides with the apex of the core body 10. It is in a state of being translated by a predetermined amount along the direction in which the line that bisects the angle (90 °) is extended to the outside. That is, the winding regulation convex portion 20 occupies the same shape (square in this embodiment) on any of the three surfaces of the core body 10 on which the winding regulation convex portion 20 is projected, and Each surface has an equal height from the outer surface of the corresponding core body 10. This is exactly the same for all the winding regulation convex portions 20.

【0012】 巻線規制凸部20以外のコア本体10の外面領域は、巻線部11となっている 。この巻線部11は、コア本体10の稜線と直交する方向に導線を巻回すること のできる三つの巻線経路11a,11b,11cを有し、任意の面を基準面とし て設定すれば、隣接する四面を側面としてこの側面を貫く巻線経路(図1では1 1cに相当する)に導線を巻回することができる。この場合、巻線は基準面の中 心を通る軸線を中心として施されたことになる。つまり、六面のうちの何れの面 を基準面としても、その基準面の中心を通る軸線を中心とする巻線経路があり、 そこに巻線を施すことができる。The outer surface region of the core body 10 other than the winding regulation convex portion 20 is a winding portion 11. The winding portion 11 has three winding paths 11a, 11b, 11c capable of winding a conductor wire in a direction orthogonal to the ridgeline of the core body 10, and if any surface is set as a reference surface, The conductive wire can be wound around the winding path (corresponding to 11c in FIG. 1) that penetrates the side surfaces with the four adjacent surfaces as side surfaces. In this case, the winding is centered on the axis passing through the center of the reference plane. That is, no matter which of the six faces is the reference plane, there is a winding path centered on the axis passing through the center of the reference plane, and the winding can be provided there.

【0013】 上記コイルコア1の形状は、換言すれば、立方体状の素材の各面に、導線を巻 回する経路(巻線経路)となる所定幅かつ所定深さの溝を、各面の中心を通り稜 線と直交するように形成したと見ることもできる。この見方によれば、溝は一面 に対して中央で交差するように二条形成されて、全体で三条あり、各々の溝はコ イルコア1の隣接しない二面の中心を通る軸線を中心としてコイルコア1の周囲 を連続して一周する。In other words, the shape of the coil core 1 is such that a groove having a predetermined width and a predetermined depth, which is a path (winding path) for winding a conductor wire, is formed on each surface of a cubic material at the center of each surface. It can also be seen that it was formed so that it passes through and is orthogonal to the ridge. According to this view, two grooves are formed so as to intersect with one surface at the center, and there are three threads as a whole, and each groove has a coil core 1 centered on an axis passing through the centers of two adjacent surfaces of the coil core 1. Around the circumference of.

【0014】 上記のごとく構成されたコイルコア1では、その六面の何れの面を基準として 見ても、全く同形状であって、その六面を基準とする限りにおいて方向性を有し ない。つまり、巻線装置が何れの面を基準としてチャッキングしても、当該基準 面の中心を通る軸線を中心とする巻線経路があり、そこに巻線を施すことができ る。The coil core 1 configured as described above has exactly the same shape when viewed from any of the six faces, and has no directivity as long as the six faces are the references. In other words, whichever surface the winding device chucks, there is a winding path centered on the axis passing through the center of the reference surface, and winding can be performed there.

【0015】 したがって、コイルコア1の何れの面を基準として搬送乃至チャッキングして も良いことから、当該コイルコア1に巻線作業を行う巻線装置や、巻線装置にコ イルコア1を搬送供給する供給装置は、その方向性を規制選択するための構造が 不要となり、構造を簡略化できる。又、コイルコア1自体も、巻線装置や供給装 置側の要因によって外形寸法を高い精度とする必要がなくなるものである。Therefore, since any surface of the coil core 1 may be transported or chucked as a reference, a winding device that performs a winding operation on the coil core 1 or the coil core 1 is transported and supplied to the winding device. The supply device does not need a structure for restricting and selecting the direction, and the structure can be simplified. Also, the coil core 1 itself does not need to have a high accuracy in its outer dimensions due to the factors of the winding device and the supply device side.

【0016】[0016]

【考案の効果】[Effect of device]

以上述べたように、本考案に係るコイルコア構造によれば、巻線時の取付方向 について方向性がなく六面の内の何れの面を基準としても全く同じ条件で巻線を 行うことができるので、巻線装置や当該巻線装置にコアを供給する供給装置はコ アの方向性を規制選択するための構造が不要となり、構造を簡略化できる。又、 コイルコア自体も、巻線装置や供給装置による方向性選択の為に性能と直接関係 のない外形寸法等を高い精度とする必要がなくなる。その結果、コストの低減が 可能となるとともに、製造工程における製造装置の故障の要因が減少し、生産効 率の向上にも寄与する。 As described above, according to the coil core structure of the present invention, there is no directivity in the mounting direction at the time of winding, and winding can be performed under exactly the same conditions regardless of which of the six faces is the reference. Therefore, the winding device and the supplying device that supplies the core to the winding device do not need a structure for restricting and selecting the directionality of the core, and the structure can be simplified. In addition, the coil core itself does not need to have high precision in external dimensions and the like which are not directly related to the performance because the directionality is selected by the winding device and the supplying device. As a result, it is possible to reduce the cost, reduce the factor of the failure of the manufacturing equipment in the manufacturing process, and contribute to the improvement of the production efficiency.
