するものである。“Prior Art” As shown in FIG. 4, a conventional line filter is a separator in which collars 2 and 3 are formed at both ends of an insulating cylindrical bobbin 1 and a winding region is divided into two in the middle of the outer peripheral surface of the cylinder. 4 is formed in a ring shape. Gears 2a and 3a are formed on the outer peripheral edges of the collars 2 and 3, respectively. Bobbin 1 is 1 along the axis
a and 1b are divided into two halves, and although not shown, a convex portion and a concave portion that engage with each other are formed on the cut surfaces of the collars 2 and 3 of the bobbin halves 1a and 1b, respectively. When they are pressed against each other, the convex portion and the concave portion are engaged with each other, and the both halves are integrally coupled. The gears 2a and 3a are used for meshing with a winding machine and rotating the bobbin 1 in the circumferential direction for winding.

してラインフィルタのコイル部が構成される。The magnetic core 5 is made of, for example, ferrite, and is formed in a letter V shape. It is difficult to form the cross section of the central side 5a of the letter of the day in a circular shape, and it is expensive, so that it is formed in a square shape. The bobbin 1 is mounted around the center side 5a. Although the magnetic core 5 is attached to the winding machine, it is difficult to rotate the bobbin 1 because the central side 5a is a square. Therefore, in the winding machine, the bobbin 1 can be replaced by the one shown in (a), (b) and (c) of FIG. From the three directions, the center side 5a and the bobbin 1 are prevented from contacting with each other, and one or both of the collar gears 2a and 3a is engaged with the gear of the winding machine to rotate the bobbin in the circumferential direction. A single wire having a diameter of 0.26 to 0.8 mm is wound in each winding section by a predetermined number of turns. Total inductance 2mH-100mH
It is said that After the winding is finished, and so that the winding does not come loose,
An adhesive is applied to a part of the outer peripheral surface of the winding. In this way, the coil portion of the line filter is constructed.

立てられ、下方に突出している。The coil portion, that is, the wound magnetic core 5 is mounted on the base 6 shown in FIG. 6 and fixed with an adhesive, and the bobbin 1 is also fixed to the base 6 with an adhesive so as not to loosen. The terminals of each winding are soldered to the terminal pins 6a to 6d to form the line filter circuit shown in FIG. The inductance of each winding section forms a parallel resonant circuit with the stray capacitance. The base 6 is composed of a frame body having a V-shape that is substantially the same as the outer shape of the magnetic core 5, and terminal pins 6a to 6d are planted at the corners of the frame body and project downward.

あった。[Problems to be solved by the invention] In the conventional line filter, in order to eliminate contact between the central side 5a of the magnetic core and the bobbin 1 in the winding work, the bobbin must be supported at three points, which results in workability. Bad things,
Since it is supported at three points, the structure of the winding machine is complicated and expensive.
この考案の目的は、これら従来の欠点を除去しようとす

ンが回動自在に装着される。"Means for Solving the Problem" (1) A magnetic core, a bobbin attached to the magnetic core, and a winding wound around the bobbin form a coil portion, and the coil portion is mounted on a base. In the present invention, in the present invention, the magnetic core is formed in a mouth shape or a day shape, the bobbin is formed of an insulating cylindrical body, and has a flange at one end thereof, and an outer peripheral edge of the flange. A gear is formed on the cylindrical body, the cylindrical body can be divided into two along the axial center, and can be joined together again. The base is composed of an insulative date-shaped frame body having a plurality of terminal pins. The central side is cylindrical, and a groove that fits with one side of the magnetic core is formed in the longitudinal direction on the outer peripheral surface of the central side, the magnetic core is mounted on the base, and the magnetic core is placed in the groove. One side of the core is fitted, and the bobbin rotates around the center side of the base. It is attached to the standing.

In this figure, parts corresponding to those in FIGS. 4 to 9 are designated by the same reference numerals, and redundant description will be omitted. In this invention, the bobbin 1 and the magnetic core 5 are the same as those shown in FIGS. 4 and 5 of the related art, respectively. However, as shown in FIG. 2, the base 6 is composed of an insulative, date-shaped frame body, and its central side 6e is cylindrical, and its outer peripheral surface is fitted with the central side 5a of the magnetic core. A groove 6f is formed in the longitudinal direction. The bottom surface of the groove 6f is made to be on the same horizontal plane as the top surface of the frame body except the central side 6e.

子ピン６ａ〜６ｄにからげて半田付される。In this manner, the bobbin 1 and the base 6 combined with the magnetic core 5 are attached to the winding machine, and one or both of the gears 2a and 3a of the bobbin 1 are meshed with the gears of the winding machine to move the bobbin 1 in the circumferential direction. Winding is done by rotating. Since the outer peripheral surface of the central side 6e of the base is circular, the bobbin 1 rotates smoothly around it, and it is not necessary to support the bobbin at three points so as not to contact the central side 5a of the magnetic core as in the conventional case. After the winding is finished, the ends of the winding are immediately entwined with the terminal pins 6a to 6d and soldered so that the winding cannot be unwound.
これ迄の説明では日の字形の磁芯を用いるものとした

け簡単で安価なものでよい。[Advantage of Invention] According to this invention, the center side 6e of the base is cylindrical, the center side 6e of the magnetic core is fitted into the groove 6f, and the bobbin 1 is mounted on the outer peripheral surface thereof. Therefore, the bobbin 1 can freely rotate around the central side 6e in this state.
Therefore, it is not necessary to support the bobbin 1 at three points as in the conventional case, the workability is improved, and the mechanism of the winding machine may be so simple and inexpensive.
この考案によれば、ボビン１、磁芯５及ベース６を一体

固定する工程が不要となる。According to the present invention, the bobbin 1, the magnetic core 5 and the base 6 are wound in a combined state, and the ends of the winding can be soldered to the terminal pins 6a to 6d of the base immediately after the winding is completed. As in the conventional case, the step of previously fixing with an adhesive so that the winding is not loosened becomes unnecessary.
また、この考案では磁芯の中央辺５ａとボビン１の内周

The step of adhering 1 to the base 6 is also unnecessary, and in addition to the above, the working time can be greatly shortened.
