Description
本考案は、コイル型インダクタに関する。 The present invention relates to a coil type inductor.
パーソナルコンピュータ本体やサーバのような電気装置に搭載される電源供給器等では、インダクタ類によって交流電流の入力時間と波形を制御・調整して、直流電流の電圧波形となるべく一致させ、電気装置の電力使用効率を向上させることが多い。これを力率改善（Ｐｏｗｅｒ ｆａｃｔｏｒ ｃｏｒｒｅｃｔｉｏｎ：ＰＦＣ）という。
単にコイルとも称されるコイル型インダクタンスは、コア材の外周に導線をコイル状に巻き付けて成り、電源供給器、モニタ、交換器、マザーボード、スキャナ、電話機、モデム等に幅広く用いられている。
In a power supply unit mounted on an electric device such as a personal computer main body or a server, the input time and waveform of the alternating current are controlled and adjusted by inductors so that the voltage waveform of the direct current matches as much as possible. It often improves the power usage efficiency. This is called power factor correction (PFC).
A coil-type inductance, also simply called a coil, is formed by winding a conductive wire around the outer periphery of a core material, and is widely used in power supply devices, monitors, exchangers, motherboards, scanners, telephones, modems, and the like.
電気と磁気とは相互に変換可能であり、電流が流れた導線の周囲には磁場が発生し、反対に、磁束を横切るコイルには電流が流れる。従って、コア材の周囲に導線を巻き付けたインダクタにおいて、コイルに電流が流れるとコイル内に磁場が発生し、電流が小さくな
ると、コイル内の磁力が電流の変化を阻止しようとするので、回路に流れる電流を安定さ
せ、電磁波の干渉を防ぐと共に、磁場の形で電気エネルギーを保存したり解放することができる。
ところで、インダクタはコア材に規定線径の導線を規定の巻き数だけ巻き付けてあり、
その保存可能な電磁力は予め定めた範囲内とすることができるが、実際の使用時には、入力電流の変化や強電の干渉によって瞬間的に飽和状態となり、電流を安定させるという機能を発揮できなくなるだけでなく、電気装置に搭載された他部品の破損を引き起こすこと
もある。
Electricity and magnetism can be converted into each other, and a magnetic field is generated around a conducting wire through which a current flows, and conversely, a current flows through a coil that crosses the magnetic flux. Therefore, in an inductor in which a conducting wire is wound around a core material, when a current flows through the coil, a magnetic field is generated in the coil, and when the current is reduced, the magnetic force in the coil tries to prevent a change in the current. It stabilizes the flowing current, prevents interference of electromagnetic waves, and can store and release electrical energy in the form of a magnetic field.
By the way, the inductor has a conductor with a specified wire diameter wound around the core material by a specified number of turns.
The storable electromagnetic force can be within a predetermined range, but in actual use, it becomes instantaneously saturated due to a change in input current or strong electric interference, and the function of stabilizing the current cannot be exhibited. In addition, it may cause damage to other components mounted on the electrical device.
本考案が解決しようとする課題は、保存エネルギーが飽和状態になりにくく、入力電流の変化や強電の干渉に耐えることができ、耐久性の高いコイル型インダクタを提供することにある。 The problem to be solved by the present invention is to provide a highly durable coil-type inductor that is resistant to saturation of stored energy, can withstand changes in input current, and strong electric interference.

A configuration in which the core material is made of a material having magnetism in an energized state by mixing iron, silicon, boron, niobium, and copper.
The core material is formed by laminating a plurality of thin base pieces.
本考案によれば、コア材の両端間に設置された永久磁石によって、電磁力を保存し、コイルに通電した時発生する磁場を延長することができるので、保存された電磁エネルギーを非飽和状態に維持することが可能で、入力電流の急激な変化や、強電の干渉に対応でき、この結果、回路に流れる電流を安定させる効果が高く、周波数特性に優れ、耐久性も高まる。
また、性能に比して軽量で嵩張らず、価格も低廉なので、様々な電気装置に幅広く用いることができる。
According to the present invention, the permanent magnets installed between both ends of the core material can preserve the electromagnetic force and extend the magnetic field generated when the coil is energized. Therefore, it is possible to cope with a sudden change in the input current and strong electric interference. As a result, the current flowing through the circuit is highly effective, the frequency characteristics are excellent, and the durability is enhanced.
In addition, it is lighter and less bulky than its performance, and its price is low, so it can be widely used in various electric devices.
