を目的としている。Therefore, not only is the working time required for the toroidal winding long and the cost is high,
The thicker the conductor is, the harder it is to wind it, and it cannot be automated. The present invention aims to solve this problem.

心円状の上下両端面である。Means for achieving the above object will be described based on Examples. Generally, a ring donut-shaped magnetic core having a rectangular cross section has four surfaces. FIG. 1 is an overhead view, and 1 is an outer peripheral side surface of a ring donut, which has a cylindrical surface. 2 is an inner peripheral side surface, which also has a cylindrical surface. Reference numerals 3 and 4 denote concentric upper and lower end surfaces.

The direction of the groove or hole is provided so that the conductor of the coil enters the groove or hole when the toroidal coil is wound. The surface of the ring donut-shaped magnetic core may be coated with an insulating material or may be covered with a case of an insulating material. In any case, the groove or hole is provided in the surface insulator portion or in the magnetic material portion.

り、溝又は穴、のことを溝と略称している。In FIG. 2, reference numeral 1 designates a groove provided on the outer peripheral side surface of the ring donut-shaped magnetic core. Further, since it is obvious that grooves can be radially provided so that the conductors of the toroidal coil can be inserted into the two surfaces shown by 3 and 4 in FIG. 1, this is not shown. In addition, one conductor does not necessarily have one conductor in one groove, and may have a groove in which no conductor enters, and two conductors may further enter in one groove. Also, it is obvious that 1 may be a hole instead of a groove, so it is not shown. The same applies to all the portions described below as a groove, and a groove or a hole is abbreviated as a groove.

Reference numeral 1 in FIG. 4 shows a cylinder similar to that in FIG. 3, and the groove 2 is provided with the covered conductor 3. Here, one conductor is attached for the sake of easy understanding, but a plurality of conductors are attached to each groove. The diameter of the cylinder 1 is approximately equal to the diameter of the inner peripheral side surface of the ring donut shown in FIG. As a method of mounting the conductor 3 in the groove 2, the conductor 3 may be pushed in the center direction of the cylinder 1,
The conductor 3 may be pushed in from above from the top.

Further, the groove 2 may be provided on the surface as shown in FIG. 4, and a through hole for inserting a conductor in the same direction as the groove may be provided inside the surface. This is the case where the conductor 3 is a round wire, and when the conductor 3 is a rectangular wire, the cross section of the groove 2 or the hole is also rectangular.

The toroidal coils can be formed by abutting or juxtaposing and soldering the contact portions to connect them in series. If the conductor coating is removed in advance in the vicinity of the contact portion and solder plating is performed, it becomes easier to solder later. Since the soldered contact portions are separated from each other by the wall of the groove, the toroidal coil is not short-circuited.
