したものが主に使用される。As shown in FIG. 2, the electromagnetic device uses a coil bobbin 1 in which at least two coil winding parts 2 and 3 are integrally connected, and a coil is wound around each coil winding part 2 and 3. It is manufactured by mounting polarization magnetic paths (hereinafter referred to as paths) 4 and 4 between the coil winding portions 2 and 3, and further mounting an inner core and an outer core (not shown). Since the coil bobbin 1 is required to have an insulating property, it is formed by molding a plastic material or by laminating a plastic material, a press board, a Kensite plate, or the like. In the case of plastic molding, the coil winding parts 2 and 3 are integrally molded via the connecting part 9. The path 4 is mainly a stack of thin electromagnetic steel plates.

ひき起こしていた。Winding of the coil around the coil winding portions 2 and 3 shown in FIG.
As shown in FIG. 3, the coil bobbin 1 is held between the bobbin holders 5 and 6. The winding method includes a spindle winding method in which the bobbin holder is rotated without moving the coil 7 (the rotating direction of the holder is indicated by an arrow A), and a flyer winding in which the bobbin holder is fixed and the coil 7 is rotated. Method (the direction of rotation of the coil 7 is indicated by an arrow B), and the necessary tension is applied to the coil 7 for the winding magnet. This tension is the tension that acts on the coil when the coil 7 is wound around the coil winding portions 2 and 3. Due to such coil tension, the inner flange 8 of each coil winding portion 2, 3
Bends outward, as shown in FIG. after this,
The path 4 is inserted and attached between the inner flanges 8 and 8. However, since the inner flange 8 is curved due to the tension at the time of winding, it becomes difficult to insert the path 4 and both inner flanges 8 and 8 are attached. It was necessary to spread it with a jig such as a screwdriver. As a result, the productivity of the electromagnetic device is reduced, and problems such as cracks in the flange 8 and damage to the coil are caused.

た。In order to eliminate such a problem, the dimension a (see FIG. 4) of the path mounting portion is increased in advance in consideration of the curvature of the inner flange 8, or the wall thickness of the flange 8 is increased to increase the winding. Methods such as reducing deformation due to tension at the time have been proposed, but in both cases, the material cost becomes high, the occupancy ratio of the windings cannot be high, the design is uneconomical, and the electromagnetic device becomes large. There was a flaw.

ことを特徴とするものである。The method for manufacturing an electromagnetic device according to the present invention is a method for manufacturing an electromagnetic device in which a coil is wound around at least two coil winding portions connected to each other, and a path is mounted between the coil winding portions. After being mounted between the coil winding parts, the coil is wound around the coil winding part.

の小型化を図ることが可能になる。As described above, according to the present invention, the path is mounted between the coil winding portions in advance before winding the coil around the coil winding portion, so that the inner flange of the coil winding portion is securely deformed. Can be prevented. For this reason, unlike the conventional case, it is not necessary to spread the curved flange to mount the path, which improves productivity and prevents the flange from being cracked and the coil from being damaged. In addition, since the deformation of the inner flange is small, the coil winding disorder is small, which can greatly contribute to the stability of the quality of the electromagnetic device. Furthermore, the path previously mounted between the coil winding parts is connected to the coil winding part. It is strongly clamped between the flanges by the tension that is applied during the winding, and it is possible to reduce the vibration and noise caused by the path. Further, it is possible to reduce the thickness of the inner flange, which makes it possible to reduce the material cost and downsize the device.
