いた。[Details and Problems of Prior Art] FIG. 3 shows a coil bobbin used in a conventional split winding insulation transformer. A coil bobbin with a conventional structure having a middle tsuba 3 has a primary winding on both sides of the middle tsuba, The secondary winding is divided and wound. However, there is often a difference in the amount of winding between the primary winding and the secondary winding, and the transformer design is determined by the side with the larger amount of winding, while the winding on the side with the smaller amount of winding is applied. The bobbin part that was not there was a wasted space.

[Purpose of device]

本考案はこれらの欠点を除去するため、１次巻線,2次巻
線の巻線量に合わせ中鍔３を移動できる構造とし、中鍔
で分離した巻枠の巻枠体積を有効に使用することを目的
としたコイルボビンを提供するにある。In order to eliminate these drawbacks, the present invention has a structure in which the inner collar 3 can be moved according to the winding amount of the primary winding and the secondary winding, and the reel volume of the reel separated by the inner collar is effectively used. The purpose of the invention is to provide a coil bobbin.

〔Example〕

本考案の実施例を第１図及び第２図により説明する。 An embodiment of the present invention will be described with reference to FIGS.

筒状巻枠１の両端に鍔２を設けて成るコイルボビンにお

巻線の仕様に合わせて巻枠上を移動し合わせてゆく。A coil bobbin provided with collars 2 at both ends of a tubular winding frame 1 is provided with guide grooves 4 on both sides in the length direction of the winding frame.
Another collar 3 is attached in the middle of the collars 2 at both ends so as to be movable along the guide groove. A plate 5 that fits into the guide groove 4 is integrally formed in the intermediate collar 3, and the middle collar 3 is attached to the reel by dividing the collar 3 into two as shown in FIG. It has a structure that fits from both ends of the reel. In addition, the slide plate 5 integrally formed with the middle collar 3 is made slightly thicker than the depth of the guide groove 4 of the winding frame, so that the plate is held by the copper wire at the time of winding, and at the time of winding and after winding. Stop moving the Tsuba. The position of the middle tsuba 3 can be easily set by putting a notch on the reel 1 that serves as a scale during molding.
Move on the reels according to the specifications of the windings.

[Effect of device]

以上述べたごとく本考案によるコイルボビンを使用する
ことにより、１次巻線,2次巻線の巻線量の不平衡差によ
る巻枠空間の不足に対応でき、又より太い線径で巻線で
き、トランスを構成したときの損失の改善につながる。
又、巻線仕様が多種にわたっても１種類のボビンで対応
でき、中鍔の位置の異なったボビンを準備する必要がな
くコイルボビンのための金型代の削減につながる。As described above, by using the coil bobbin according to the present invention, it is possible to cope with the shortage of the winding frame space due to the unbalanced difference in the winding amount of the primary winding and the secondary winding, and it is possible to wind with a thicker wire diameter. It leads to improvement of loss when the transformer is constructed.
In addition, one bobbin can be used for various winding specifications, and it is not necessary to prepare bobbins having different positions of the middle collar, which leads to a reduction in die cost for the coil bobbin.
