FIG. 2 is a sectional view of an example of a conventional rotary transformer. This conventional example is a two-channel rotary transformer, in which windings 13 and 14 are inserted and fixed into two concentric annular grooves 11 and 12, and lead wires 16 and 17 of the windings are is led out through the through hole of the ferrite core 18 to the back surface of the surface on which the winding is applied, and further inserted into the tube 15, which is bonded to the back surface of the ferrite core 18.
このように、リード線をチユーブへ通すことは
リード線の各チヤンネル間の区別を容易にするた
めであり、更に、リード線を保護するためであ
る。 Passing the lead wires through the tube in this way is to facilitate differentiation between each channel of the lead wires, and also to protect the lead wires.
従来は、チユーブをフエライトコアの裏面に接
着していた為、接着強度が弱く、しかも接着剤が
フエライトコア裏面に広がり、この広がり過ぎた
接着剤を取り除く作業が必要となり工数が多いな
どの問題点があつた。
Conventionally, the tube was glued to the back side of the ferrite core, which resulted in problems such as weak adhesive strength and the adhesive spreading to the back side of the ferrite core, requiring work to remove the excess adhesive, which required a lot of man-hours. It was hot.
本考案は、上記の問題点を解決するロータリー
トランスを得るために、チユーブをフエライトコ
アの貫通孔に挿入して接着固定するものである。
In order to obtain a rotary transformer that solves the above problems, the present invention involves inserting a tube into a through hole of a ferrite core and fixing it with adhesive.

め、リード線の保護についても向上する。
Since the tube is inserted into the through-hole of the ferrite core and bonded, the bonding area is widened and the bonding strength is improved.Furthermore, since the tube is bonded within the through-hole, it is possible to prevent the adhesive from flowing to the back surface of the ferrite core as much as possible. This eliminates the step of removing the tube later, and since the tube is closer to the bottom of the groove where the winding is performed, protection of the lead wire is also improved.

FIG. 1 shows a sectional view of an embodiment of the present invention. This embodiment is a two-channel rotary transformer, with two concentric annular grooves 11 and 1.
2, windings 13 and 14 are arranged. This winding 1
The lead wires 16 and 17 of No. 4 are connected to the ferrite core 18.
The winding wire is led out to the back surface of the core through a through hole provided from the bottom surface of the winding groove to the back surface of the core. The lead wires 16 and 17 led out to the back surface are inserted into the tube 15, and the tube 15 is inserted into the through hole of the core and bonded.
また、チユーブは、巻線の巻き始めと巻き終り
のそれぞれのリード線で色分けしても良く、当然
貫通孔の大きさは、チユーブが挿入可能な大きさ
とする。 Further, the tube may be color-coded depending on the lead wires at the beginning and end of the winding, and the size of the through hole is of course large enough to allow insertion of the tube.
