ている。In order to improve the above-mentioned drawbacks, the present inventor filed an application for a rotary transformer in which an ultraviolet-curable modified acrylic adhesive was used for the ferrite core and the windings in Application No. 59-102345, and reduced the number of man-hours by applying a 2-turn adhesive. Good results such as improved strength have been obtained.

第３図に示す様に、巻線を加圧した状態にて、紫外線を
照射し、接着剤を硬化させる必要がある。As shown in FIG. 3, it is necessary to cure the adhesive by irradiating ultraviolet rays while the winding is under pressure.

いた。Due to the above drawbacks, multi-channel rotary trucks
At the factory, the process of applying adhesive to each groove, inserting the coil and applying pressure, and then irradiating it with ultraviolet light (hardening the adhesive) was repeated for several grooves. Therefore, the cost increases due to the complexity of the process, and the advantage of simplifying the process due to the use of the ultraviolet curable modified acrylic adhesive is lost.

An ultraviolet curable modified acrylic adhesive 2 is applied to each winding groove of the ferrite core 1 for a multi-channel rotary transformer shown in FIG. Next, apply a curing accelerator to the adhesive surface of the winding as shown in Figure 1C.
Each winding is inserted one by one into the corresponding winding groove, pressure is applied, and temporary bonding is performed by anaerobic bonding. This adhesive strength is several hundred grams, which is sufficient for temporary bonding of winding wires. Furthermore, after temporarily bonding all the windings, final curing is performed by irradiating ultraviolet rays, including the parts that do not come in contact with the curing accelerator. Therefore, it is also suitable for multi-channel rotary transformers. Therefore, the UV-curable adhesive can be effectively used without having to repeat the winding bonding process.
