[Detailed description of the invention] When winding a coil around a coil bobbin, the coil end edge facing the inner surface of the flange is placed at least a predetermined distance from the inner surface of the flange on at least one axial end of the coil bobbin.
Regarding coil devices that need to be spaced apart, in particular, a coil device that can be separated by a predetermined distance in a reliable and simple manner.

As a typical coil device, in a general transformer, etc., when a coil is wound around a coil bobbin having flanges at both ends, a plurality of layers are formed between the axial edge of the coil and the lead wire or in the radial direction of the coil bobbin. When winding a coil, it is necessary to secure the insulation distance or creepage distance between the axial edges of each coil, so it is required to keep the axial edges of the coil a predetermined distance from the inner surface of the flange. come.

このような場合には、全稈の熟練者でない限り、各コイ

うにし乍ら何の目安もなく直接に巻いていくことは不可

In such cases, unless you are an expert in all culms, it is impossible to wind each coil directly without any guideline while keeping the end edge of each coil at a predetermined distance from the inner surface of the flange. be.

そこで、従来からも、各コイルの端縁の位置決め対して
の考察がなされていたが、結局は第1図に示す例に帰結
し、以下述べる欠点を有していたのである。
Therefore, consideration has been made in the past regarding the positioning of the end edges of each coil, but in the end this resulted in the example shown in FIG. 1, which had the following drawbacks.

第1図示の従来手法の典型につき述べると、両端にフラ

To describe a typical conventional method shown in FIG. While making contact with the inner surface 2a, it is fitted onto the coil bobbin 1 from both sides.

この枠部材の幅W、即ち筒形のコイルボビンの長さ方向
に沿う長さWを、巻き付けるコイルとフランジ内面2a
との予定離間距離とし、また、半径方向の厚味りを、巻
き付けるコイルの厚味と等しくしておくのである。
The width W of this frame member, that is, the length W along the length direction of the cylindrical coil bobbin, is set between the coil to be wound and the flange inner surface 2a.
The thickness in the radial direction is made equal to the thickness of the coil to be wound.

このようにして、コイルをこの枠部材3,3の軸方向内
面に沿わせて巻始めることにより、予定の離間距離Wを
確保し、且つコイルの全厚味りについてこの条件を満足
せんとしているのである。
In this way, by starting to wind the coil along the axial inner surface of the frame members 3, 3, the planned separation distance W is secured, and this condition is satisfied for the total thickness of the coil. It is.

しかし、この手法は次に述べる欠点がある。However, this method has the following drawbacks.

先づ第一に、枠部材3,3を予じめ接着材その他により

厄介となり、従って予じめ接着しておくにしても、固体

る接着剤を使って時間と手間をかけねばならない。
First of all, unless the frame members 3, 3 are fixed in advance with adhesive or other means in a predetermined position where they come into contact with the flange inner surface 2a and the bobbin outer circumferential surface, winding the coil will be extremely troublesome. Therefore, even if it is bonded in advance, since it is made of a solid plastic material, it is necessary to use an adhesive with sufficient adhesive strength and spend time and effort.

また、各コイルボビン1の径に応じて夫々対応する枠部
材3,3を用意せねばならず。
Further, corresponding frame members 3, 3 must be prepared according to the diameter of each coil bobbin 1, respectively.

従って枠部材の成形型の数も多くなり、支出も莫迦にな
らない。
Therefore, the number of molds for the frame members increases, and the expense does not become prohibitive.

同じ理屈で、半径方向の厚味りも一定となってしまうか
ら、6径や巻回数の異なるコイルには適用できない。
By the same logic, the thickness in the radial direction is also constant, so it cannot be applied to coils with 6 diameters or different numbers of turns.

たり、巻き締めが不足したりしてしまう。
Furthermore, when several coils are stacked in the radial direction, the lower coil is tightened when the insulating tape sandwiched between them and the upper coil is wound, which improves the fit between the upper and lower layers. If the frame member 3 is used, it will become unnecessarily bulky as a whole, and the winding will not be tightened enough.

In view of the above, this proposal is easy to operate and ensures a reliable creepage distance.
The main purpose of this invention is to provide a coil device with a wide range of thickness flexibility.

以下、第2,3図に即して本案基本的実施例に就き詳記
する。
A basic embodiment of the present invention will be described in detail below with reference to FIGS. 2 and 3.

先づ、巻き付けるべきコイルの軸方向端縁と、フランジ

First, in accordance with the planned distance W between the axial end edge of the coil to be wound and the inner surface 2a of the flange 2, a flexible strip-shaped insulating material 4 such as an insulating tape is prepared with a width W equal to the distance. .

この実施例では、一般に、絶縁材4として少くとも一面

In this embodiment, generally an insulating tape having an adhesive layer on at least one surface and commercially available as the tape winding 5 is used as the insulating material 4, but in order to obtain the required tape width W,
It is also convenient to cut the entire tape roll into rounds of a predetermined width W using an appropriate cutting means while the tape roll 5 is still unrolled.

このようにして準備した絶縁テープ4を、側縁がフラン

The insulating tape 4 thus prepared is cut so that the side edge is in contact with the inner surface of the flange 2a, and the adhesive layer is wound along the outer periphery of the bobbin until it has the required thickness (FIG. 3).

その後、コイル6を巻き付ける際に、このコイルの対向

Thereafter, when winding the coil 6, the opposing edges of the coil are brought into contact with the corresponding side edges (side edges facing inward in the axial direction) 4a of the layer of tape 4, thereby positioning the coil in the axial direction. .

勿論、コイルを半径方向に積層する場合にも、各コイル
について同様の手当てをすることができる。
Of course, similar arrangements can be made for each coil when the coils are stacked in the radial direction.

In FIG. 3, only the immediately upper layer coil 6' is illustrated, but after applying the inter-coil insulating tape 7 to the lower coil circumferential surface by a well-known method, the necessary schedule for this coil 6' is similarly applied. A tape 4 having a distance W' is prepared and wound to a predetermined thickness D', and the coil 6' is wound using the inner edge group as a positioning surface.

必要に応じて更に積層数を増やすことは自由である。It is free to further increase the number of laminated layers as necessary.

また、図示の場合は、一方のフランジ2側のみについて

Further, in the illustrated case, the creepage distance is ensured only on one flange 2 side, but a similar configuration may be adopted on the opposite flange side (not illustrated).

However, in general, when this coil device is made into a transformer by attaching an iron core using a known configuration or by attaching a terminal block for a coil lead wire, the configuration of the present invention does not apply to the flange on the terminal block side. In many cases, it is only necessary to apply it to the inner surface.

Note that the central through hole 8 of the bobbin 1 is E when used as a transformer.
This is based on the assumption that the one leg of the I-type or U-type iron core will penetrate as is well known.

以上のように、本号に依ると、コイルに応じての予定距

理的である。
As described above, according to this issue, the planned distance W for each coil can be set arbitrarily by simply modifying a commercially available tape that is easily available, and it is possible to set the planned distance W according to the coil as desired by simply making a small modification to a common and easily available commercially available tape. There is no need to prepare a dedicated frame member for this, which is extremely rational.

特に、厚味については、全く自在であって、コイル厚味
に応じて単にテープ4の巻回数を変えるだけで良い。
In particular, the thickness is completely adjustable, and it is sufficient to simply change the number of turns of the tape 4 depending on the thickness of the coil.

更に、このテープ4自体、柔軟性に富むため、コイル装

点がある。
Furthermore, since the tape 4 itself is highly flexible, each layer has good conformability when being wound up as a coil device, and even if the coil thickness deviates from the designed value, it has the advantage of being able to follow it well.

また、テープ4の巻き付は作業は、誰にでも手綱れた作

In addition, the winding of the tape 4 is a task that anyone can handle, and is efficient and difficult to differentiate between people, and in the end, it is possible to minimize product variations.
