Description

本発明は、電機機器に使用される空芯コイルに関するものである。 The present invention relates to an air-core coil used for electrical equipment.

自己融着線を整列巻し空芯コイルを形成するとコイルの最内周に巻始線、コイルの外周に巻終線がある。この巻始線、巻終線は他の機材との接続にリード線として利用される。このとき、巻始線は必ずコイルの内側にあるので接続のためにコイルの外側に導出しなければならない。普通はコイルの端面を横断して渡りコイルの外側に導出するが、渡り線分だけコイルの高さ寸法が余分に必要になる。
空芯コイルの巻始線をコイルの高さロスをなくしコイルの外側に導出するための方法として、取付板に穴や溝を設ける、配線基板を用いコイル窓内でランドとリードを接続する、２枚のコイルを重ね張り合わせ互いの巻始線を接合し互いの巻終線をリード線とするΩ型コイルを使うなどの工夫がされている。
特開昭５８−５１５０２号公報 When self-bonding wires are aligned and wound to form an air-core coil, there is a winding start line on the innermost periphery of the coil and a winding end line on the outer periphery of the coil. The winding start line and winding end line are used as lead wires for connection to other equipment. At this time, since the winding start line is always inside the coil, it must be led out of the coil for connection. Normally, it is led out to the outside of the crossover coil across the end face of the coil, but an extra coil height dimension is required for the crossover line.
As a method for deriving the winding start wire of the air-core coil to the outside of the coil without losing the height of the coil, a hole or groove is provided in the mounting plate, the land and the lead are connected within the coil window using a wiring board, The idea is to use two Ω-type coils that overlap each other and join each other's winding start wires and the other winding end wires as lead wires.
JP 58-51502 A

コイルの巻始線をコイルの端面上を這わせ外側に導出すると、電線一本分の無駄な厚みを必要とするので上述のような工夫がされている。
取付板に溝を設けることができない、コイルの窓が小さくて窓内で半田工事ができないなどの使用条件によってはΩ型コイルを使うことになる。しかしΩ型コイルは製作が難しくコスト高を招く。 If the coil winding start line is drawn over the end face of the coil and led out to the outside, a wasteful thickness corresponding to one electric wire is required, and thus the above-described device is devised.
Depending on the usage conditions, such as the inability to provide a groove in the mounting plate, or the fact that the coil window is too small to be soldered in the window, an Ω-type coil is used. However, Ω-type coils are difficult to manufacture and cause high costs.

About.

本発明は整列巻した空芯コイルの内側にあるリードをコイルの端面を横断し、線１本分のコイルの高さ方向のロスをなくして、コイルを小型化し、コイルを用いる電機装置を小型する効果を奏する。 The present invention crosses the end face of the coil with the lead inside the air-core coil wound in an aligned manner, eliminates the loss in the height direction of the coil for one wire, downsizes the coil, and downsizes the electrical device using the coil. The effect to do.

本発明は整列巻した空芯コイルの端面にコイルの内側から外側にコイル端面を横断して壕状の窪みを配設してコイルの巻き始め線を壕を通してコイルの外側に導出する導出壕を付与した空芯コイルである。
自己融着線を巻回して空芯コイルを形成するとコイルの最内周に巻始線が、そしてコイルの外周に巻終線が存在する。コイルの外周とは、空芯コイルの巻層の最上層の部分を言う。この巻始線と巻終線はコイルと他の機材との接続リード線として使用されるが、巻始線は空芯コイルの内側にある。内側とは、コイルの巻層の最下層の部分を言う。内側にあるため巻始線として利用するためにコイルの外側に導出すると巻始線は、コイルの端面上を横断して渡りコイルの外側に導出する。コイル端面は空芯コイルの巻層が上がる最上層の折り返しの部分を言い、渡るとは、巻始線を各巻層を横断しながら巻層の最下層から最上層へコイル端面に沿って引き返すことを言う。このように巻始線がコイルの端面を横断して渡るとコイルの高さの寸法は渡り線分高くなる。この増加するコイルの高さは、コイルの機能には寄与しないので、小型化を図る電機機器からみればコイルのロスである。このコイルの線１本分の無駄な厚みをなくすために、本発明は空芯コイルの端面にコイルの内側から外側に壕状の窪みを設ける。この壕を通して巻始線を外側に導出する。壕を形成するには空芯コイルの端面を、所定の位置、巾、長さと深さになるような凸部を設けた板で押圧する。壕は複数条設けることができ、他の電気部品のリードを導出することもできる。全体の高さをコイル高さを維持しつつ、コイルの結線が行えるため、コイルを挟む電磁気回路上の無効空間を最小にする効果を奏する。 According to the present invention, a lead-out rod is provided on the end surface of the air-core coil that is wound in an aligned manner so that a saddle-like depression is disposed across the coil end surface from the inside to the outside of the coil so that the winding start line of the coil is led out to the outside of the coil. It is the provided air core coil.
When an air-core coil is formed by winding a self-bonding wire, a winding start line exists on the innermost circumference of the coil and a winding end line exists on the outer circumference of the coil. The outer periphery of a coil means the uppermost layer part of the winding layer of an air-core coil. The winding start line and winding end line are used as connection leads between the coil and other equipment, but the winding start line is inside the air-core coil. The inner side refers to the lowermost part of the coil winding layer. Since it is inside, when it is led out to the outside of the coil for use as a winding start line, the winding start line crosses over the end face of the coil and leads to the outside of the coil. The coil end face refers to the folded part of the uppermost layer where the winding layer of the air-core coil rises. Crossing means that the winding start line crosses each winding layer and is turned back from the lowermost layer to the uppermost layer along the coil end face. Say. When the winding start line crosses across the end face of the coil in this way, the height dimension of the coil becomes higher. The increasing coil height does not contribute to the function of the coil, and is therefore a loss of the coil from the viewpoint of the electrical equipment to be miniaturized. In order to eliminate the useless thickness of one coil wire, the present invention provides a saddle-like depression on the end face of the air-core coil from the inside to the outside of the coil. The winding start line is led out through this hook. In order to form the ridge, the end face of the air-core coil is pressed with a plate provided with a convex portion having a predetermined position, width, length and depth. A plurality of scissors can be provided, and leads of other electrical parts can be derived. Since the coil can be connected while maintaining the coil height as a whole, the effect of minimizing the invalid space on the electromagnetic circuit sandwiching the coil is achieved.

実施例をあげて具体的に説明する。
図１は、従来の空芯コイルであって、１は空芯コイル、２は巻始線、３は巻終線である。この従来例では、巻始線はコイルの端面上を横断しないとコイルの外に導出できない。
図２は、本発明の実施例の一つであって、導出壕を付与した空芯コイル１の端面に導出壕４を設けた実施例である。そして、図３に示すように巻始線２がこの導出壕を通ってコイルの外に導出される。したがって巻始線２は、コイル１の端面上を横断しない。また図４には、ホール素子など他の部品５をコイルの空芯内に固定し、他のリード線とを導出壕を通してコイルの外に導出した本発明の他の実施例が示されている。この例では、導出壕が１箇所なので、巻始線と他のリード線６は、一緒に１ケの導出壕によりコイルの外に導出されている。
図５の実施例では、導出壕を２箇所設け、他の部品のリード線６とコイルの巻始線を別々に導出している。
この他、図６に示されているように、コイルの側部に導出壕と連続する溝を設けてもよい。 An example is given and it demonstrates concretely.
FIG. 1 shows a conventional air-core coil, in which 1 is an air-core coil, 2 is a winding start line, and 3 is a winding end line. In this conventional example, the winding start line cannot be led out of the coil unless it crosses the end face of the coil.
FIG. 2 shows an embodiment of the present invention in which a lead rod 4 is provided on the end face of the air-core coil 1 provided with the lead rod. Then, as shown in FIG. 3, the winding start wire 2 is led out of the coil through the lead rod. Therefore, the winding start wire 2 does not cross over the end face of the coil 1. FIG. 4 shows another embodiment of the present invention in which another component 5 such as a Hall element is fixed in the air core of the coil, and other lead wires are led out of the coil through a lead rod. . In this example, since there is one lead rod, the winding start wire and the other lead wires 6 are led out of the coil together by one lead rod.
In the embodiment of FIG. 5, two lead rods are provided, and lead wires 6 of other components and coil start wires are led out separately.
In addition, as shown in FIG. 6, a groove continuous with the lead rod may be provided on the side of the coil.

本発明の空芯コイルはリード線１本分の無駄な空間がなく、これを用いた電機装置を小型化できるので、電機機器に広く使用される。 The air-core coil of the present invention does not have a useless space for one lead wire, and an electric device using the lead wire can be miniaturized, so that it is widely used in electric equipment.
