Title (EN) MAGNETIC COUPLING-TYPE ISOLATOR
(FR) ISOLATEUR DE TYPE COUPLEUR MAGNÉTIQUE
(JA) 磁気結合型アイソレータ
Abstract: front page image
(EN)Provided is a magnetic coupling-type isolator capable of preventing the short circuit between wiring patterns, and suppressing the occurrence of parasitic capacitance. The magnetic coupling-type isolator is provided with a coil (2) for generating an external magnetic field by means of an input signal, and magnetic detection elements (R1 to R4) which are electrically insulated from the coil (2) and are arranged in the position in which magnetic coupling is possible so as to detect the external magnetic field for conversion into an electrical signal.  The magnetic detection elements (R1 to R4) constitute a bridge circuit, wherein the wiring patterns are set so as not to cross one another in a planar view.
(FR)L'invention propose un isolateur de type coupleur magnétique qui permet d'éviter les courts-circuits entre des motifs de câblage ainsi que de limiter l'apparition de capacités parasites. L'isolateur possède une bobine (2) servant à produire un champ magnétique externe à partir de signaux d'entrée. Il possède également des éléments de détection magnétique (R1 à R4) placés de sorte à être électriquement isolés de ladite bobine (2) et à permettre un couplage magnétique. Ils servent à détecter ledit champ magnétique externe et à le convertir en signaux électriques. Lesdits éléments de détection magnétique (R1 à R4) forment un circuit en pont, et sont dirigés de sorte que les motifs de câblage ne se croisent pas en vue en plan.
(JA)【課題】 特に、配線パターン同士の短絡を防止でき、また寄生容量の発生を抑制することができる磁気結合型アイソレータを提供することを目的としている。 【解決手段】 入力信号により外部磁界を発生させるためのコイル2と、コイル2と電気的に絶縁されるとともに磁気的結合が可能な位置に配置され、前記外部磁界を検出して電気信号に変換するための磁気検出素子R1~R4と、を有する。前記磁気検出素子R1~R4はブリッジ回路を構成しており、配線パターン同士が、平面視にて交差しないように引き回されている。
