つた。 Conventionally, the electromagnet of this type of electromagnetic contactor has been coated with epoxy resin or the like to protect the operating coil and its control parts from the impact of the contactor body, and a fixed iron core that passes through the operating coil. must be constructed so as not to come into contact with the epoxy resin so that the input impact will not propagate to the operating coil and each control component. On the other hand, the operating coil and each control component are designed to improve assembly workability.
Must be placed on a flat surface. However, if an E-shaped or U-shaped fixed core is used in the above configuration, the fixed core passes through the placement surface of each of the above components, reducing the installation area for each component. There was a problem that it became difficult.

This is what we are trying to provide.
以下、この考案の一実施例を第１図ないし第６
図によつて説明する。 An embodiment of this invention is shown below in Figures 1 to 6.
This will be explained using figures.

接続している。バリスタ１は、外来サージの侵入
を防止するため交流側に接続してある。 First, the electromagnet circuit will be explained with reference to FIG. 1. The circuit components are composed of a varistor 1, a changeover switch 2, a resistor 3, a capacitor 4, a diode 5, and an operating coil 6. The changeover switch 2 is closed when the main contact of the electromagnetic contactor 7 (FIG. 2) is open, and is open when the main contact is closed. The capacitor 4 and the resistor 3 are connected in series and in parallel to the changeover switch 2. The diode 5 performs full-wave rectification of the alternating current voltage AC, and the operating coil 6 is connected to its direct current output end. The varistor 1 is connected to the alternating current side to prevent invasion of external surges.

直流励磁の場合においては、前述のように、操作
コイルに印加される電圧を切替スイツチ等によつ
て変化させる必要がある。 In the above configuration, when an AC voltage is applied,
Initially, the changeover switch 2 is closed, so the full voltage of full-wave rectification of the AC voltage is applied to the operating coil 6, and the movable part of the electromagnetic contactor 7 is driven by electromagnetic force, causing the main contact to close. At the same time as the circuit is closed, the changeover switch 2 is opened. When the changeover switch 2 is opened, an alternating current voltage is applied to the diode 5 via the capacitor 4. Since the AC voltage dropped by the capacitor 4 is applied to the operating coil 6, the movable part is held by a weaker electromagnetic force than when it is turned on, and the power consumption of the operating coil 6 becomes small. In the case of electromagnets that apply AC voltage directly to the operating coil, the magnetomotive force and power consumption of the operating coil change due to changes in reactance during turning on and holding.
In the case of DC excitation, as mentioned above, it is necessary to change the voltage applied to the operating coil using a changeover switch or the like.
つぎに、交流電圧を消去すると、前記可動部が

記放電電流の値を制限する。 Next, when the AC voltage is erased, the movable part returns to its original state and at the same time the changeover switch 2 closes.
The electric charge remaining in the capacitor 4 is discharged to the changeover switch 2 through the resistor 3, and the electrical insulation generated on the contact surface of the changeover switch 2 is electrically removed. Note that the resistor 3 limits the value of the discharge current so that the contacts do not weld.
