共振を起す欠点がある。 In order to attenuate these disturbance voltages, a Chi-Yoke coil is inserted into the telephone circuit, but since the Chi-Yoke coil using a drum core is a magnetically open magnetic path, its effective magnetic permeability is low and it can be made in any shape and large. In order to obtain inductance, it is necessary to increase the number of wires in the winding, and as a result, the DC resistance increases due to the length of the winding.Furthermore, due to the stray capacitance between the windings, the value of Q changes at a certain frequency. It has the disadvantage of causing high frequency resonance.

提供することにある。 The purpose of the present invention is to eliminate such drawbacks of the conventional method, to increase the effective permeability by bringing the magnetic circuit closer to a closed magnetic circuit by winding it in the annular groove of the drum core, and to reduce the DC resistance by reducing the number of turns of the winding. It is an object of the present invention to provide a chiyoke coil using a winding material for a drum core, which reduces the value of the coil Q, suppresses frequency resonance as much as possible, and prevents noise from entering.

巻く場合が多い。 FIG. 1 shows a sectional view of a chiyoke coil according to the present invention. The figure shows a chiyoke coil in which the winding material shown in FIG. 2 is wound around the grooves of a two-flange drum-shaped core 1 having an annular groove formed on the outer periphery. The winding material shown in the figure is made of a magnetic material such as permalloy or amorphous magnetic material, as shown in FIG.
A conductor 5 is bonded to one surface of a magnetic strip 3 having a width slightly smaller than the width W of the groove by, for example, vapor deposition or plating, and the outer surface thereof is covered with an insulating coating 2. Since the winding material has such a structure, when this winding material is wound many times around the groove of the core 1 with the conductor film 5 inside, the magnetic strip 3 will be caused by the flow of magnetic flux 4 shown in Fig. 1. A closed magnetic path is constructed for each winding layer. Therefore, the effective magnetic permeability is increased, and the number of turns required is smaller than that required to obtain the same inductance using the same core using the conventional method, and the Q value of the coil with reduced DC resistance can be reduced. For convenience, FIG. 1 shows a cross-sectional view when the winding material shown in FIG. 2 is wound three times, but in reality it is often wound several tens of times.

However, insulation from the winding material of the adjacent layer is ensured, and the number of turns can be increased due to the smaller thickness, and the lead wire can be connected to the conductor 5.
It has the advantage of being easy to connect.
