Title
(EN) ELECTRIC CURRENT DETECTOR AND CORE COMPONENT USED FOR SAME
(FR) DÉTECTEUR DE COURANT, ET COMPOSANT DE NOYAU MIS EN ŒUVRE DANS CELUI-CI
(JA) 電流検出器及びそれに用いるコア部品
Abstract
(EN) An electric current detector has, provided within an exterior case (1): an annular core (2) which has a magnetic gap (G); and a Hall element (41) which is located within the magnetic gap of the core (2) and detects the magnitude of an electric current passing through the core (2). The core (2) has a core component formed integrally therewith. The core component is configured by forming a mold resin section (3) on one or more portions of the core (2) so as to be disposed along the magnetic path of the core (2), and the mold resin section (3) covers the surface of the core (2) for a part of the entire length thereof along the magnetic path. The core component is affixed to the inside of the exterior case (1) with the surface of the mold resin section (3) in contact with the inner surface of the exterior case (1).
(FR) L'invention concerne un détecteur de courant dans lequel un noyau (2) de forme annulaire et possédant un espace magnétique (G), et un élément à effet Hall (41) positionné à l'intérieur de l'espace magnétique (G) du noyau (2) et détectant la grandeur d'un courant électrique qui traverse le noyau (2), sont installés à l'intérieur d'un boîtier extérieur (1). Dans le noyau (2), une partie en résine moulée (3) qui couvre la surface du noyau (2) sur une portion de l'ensemble de la longueur le long d'un circuit magnétique, est formée en un ou plusieurs endroits le long du circuit magnétique. Un composant de noyau est ainsi configuré d'un seul tenant. Ce composant de noyau est fixé dans la partie interne du boîtier extérieur (1) dans un état dans lequel la surface de la partie en résine moulée (3) est en contact avec la face interne du boîtier extérieur (1).
(JA)  本発明に係る電流検出器においては、外装ケース1内に、磁気ギャップGを有する環状のコア2と、該コア2の磁気ギャップ内に位置して該コア2を通過する電流の大きさを検知するホール素子41とが配備されている。ここで、コア2には、その磁路に沿う全長の内、一部の長さに亘ってコア2の表面を覆うモールド樹脂部3が、磁路に沿う1或いは複数箇所に成形されて、一体のコア部品が構成されており、該コア部品は、モールド樹脂部3の表面が外装ケース1の内面に接触した状態で、外装ケース1の内部に固定されている。
