絶縁性の向上を計ることのできるコイルボビンに
関するものである。[Detailed Description of the Invention] The present invention relates to a coil bobbin in which a coil is wound in sections and the insulation between the winding layers can be improved.
従来における分割巻線用のコイルボビンとして
は、第１図〜第４図に示すように構成されてい
た。 Conventional coil bobbins for split windings have been constructed as shown in FIGS. 1 to 4.
まず、第１図、第２図に示すものは、筒状の巻

設け、このスリツト４の一方の巻線溝３側に鍔２
より少し高さの低い壁５を設けて構成されてい
る。 First, in the example shown in Figs. 1 and 2, a plurality of flanges 2 are provided at regular intervals on the outer periphery of a cylindrical winding portion 1 to form a plurality of winding grooves 3, and slits 4 are provided on the flanges 2 except for both ends or one end, and the flanges 2 are provided on one winding groove 3 side of the slits 4.
It is constructed by providing a wall 5 that is slightly lower in height.
この構成で第１図は第１図の巻線溝３に第１巻
線層６、第２の巻線溝３に第２巻線層７を施した
状態を示しており、上記第１巻線層６から第２巻
線層７に移るときには鍔２のスリツト４を通り、
連続的に巻線されていく。 With this configuration, FIG. 1 shows a state in which the first winding layer 6 is applied to the winding groove 3 of FIG. 1, and the second winding layer 7 is applied to the second winding groove 3, and the first When moving from the wire layer 6 to the second winding layer 7, it passes through the slit 4 of the collar 2,
The wire is wound continuously.
この構成においては、巻線の前層の巻終り８と
次層の巻終り９の間の沿面距離１０が小さく、後
工程における真空注型などによりスリツト４の中

つていた。 In this configuration, the creepage distance 10 between the winding end 8 of the previous layer and the winding end 9 of the next layer is small, and an insulator with excellent adhesion is formed in the slit 4 by vacuum casting in a later process. The interlayer insulation had to be ensured by completely filling the layers, which resulted in large costs for production equipment and manufacturing processes.
また、第３図、第４図に示すものは、筒状の巻
線部１１の外周に一定の間隔を保つて複数の鍔１
２を設けて複数の巻線溝１３を形成し、この鍔１
２のうち両端あるいは一端を除く鍔１２に斜め方
向のスリツト１４を形成して構成され、第１の巻
線溝１３、第２の巻線溝１３に巻線１５を施した
のが第３図で、第１の巻線溝１３から第２の巻線
溝１３に巻線１５が移るときは斜めのスリツト１
４を通つて連続巻線が可能に構成されている。 Moreover, what is shown in FIG. 3 and FIG.
2 to form a plurality of winding grooves 13, and this collar 1
Figure 3 shows a structure in which diagonal slits 14 are formed in the collar 12 excluding both ends or one end of the 2, and a winding 15 is provided in the first winding groove 13 and the second winding groove 13. When the winding 15 is transferred from the first winding groove 13 to the second winding groove 13, the diagonal slit 1
Continuous winding is possible through 4.
この構成においては巻線１５の前層と次層との
沿面距離は長くなるが、スリツト１４を通る移り
線１６と前層の巻始め間の沿面距離が小さくな
り、後工程で真空注型などによりスリツト１４の
中に密着性の優れた絶縁物を充填して絶縁性を確
保する必要があり、生産設備、製造工程が複雑と
なりコスト面で不利になるとともに、成型金型の
保全上スリツト１４をあまり長く構成できないと
いつた欠点があつた。 In this configuration, the creepage distance between the previous layer and the next layer of the winding 15 becomes long, but the creepage distance between the transition wire 16 passing through the slit 14 and the beginning of the winding of the previous layer becomes small, and vacuum casting etc. Therefore, it is necessary to fill the slit 14 with an insulating material with excellent adhesion to ensure insulation, which complicates the production equipment and manufacturing process, which is disadvantageous in terms of cost. The drawback was that it could not be configured for very long periods.
本考案は以上のような従来の欠点を除去するも
のである。 The present invention eliminates the above-mentioned drawbacks of the prior art.
