してトロイダルコイル3を製造していた。Structure of conventional example and its problems In the conventional manufacturing method of toroidal coil, winding was performed on a ready-made ferrite toroidal core. There are three winding methods: hand winding and mechanical winding. When winding is done by hand, as shown in Figure 1 A to C, the winding length corresponding to the number of turns of the conductor is determined in advance. The toroidal coil 3 was manufactured by preparing the winding wire 2 for cutting, holding one end of the winding wire 2, and repeatedly passing it through the toroidal core 1 to wind the wire.

ど巻線時間が倍加した。Furthermore, even when winding is performed using a toroidal winding machine, the actual situation is that winding cannot be performed unless the conductor wire corresponding to the winding length described above for manual winding has been wound around the wire storage ring in advance. . As described above, both the manual method and the method using a toroidal winding machine took a considerable amount of time, and the winding time doubled as the number of wires in the coil increased.
従ってトロイダルコイルは従来から大量生産には遺さな
いコイルであるとされていた。Therefore, toroidal coils have traditionally been considered to be coils that should not be left in mass production.

される場合とがある。First, as shown in Fig. 2A, winding 6 is applied to a bobbin 6 made of a ferrite resin composite material having a hollow hole 4 as shown in Fig. 2, and then it is formed into a circular shape 7 as shown in Fig. 2C. do. Next, a ferrite resin composite material 8 is injected through the hollow hole 4 to form a closed magnetic circuit 9, thereby forming a toroidal coil 1o as shown in FIG. The lead wire 11 may be soldered directly to another connection body, or may be wound around a terminal of a terminal board and then soldered.

のである。Effects of the Invention According to the present invention, the winding can be performed using an automatic winding machine, and the ferrite resin composite material can also be automatically injected using an injection molding machine, which is different from the conventional method. The toroidal coil, which had been considered a non-automated, mass-produced coil, now has an automated mass-production method, which has significantly contributed to the development of industry.
