<p>PURPOSE:To compact a detector and to reduce its cost by composing a core of a steel plate and molding the core, a magnetoelectric converting element, and interface substrates in a case. CONSTITUTION:An insulating conductor insertion part 2 where a copper bar 3 as a conductor to be measured is inserted and fitted is provided to one side part of the case 1, and the core 7 one or plural steel plates is arranged circumferentially at the outer periphery of the conductor insertion part 2 in the case 1. Further, both end parts of the core 7 are arranged opposite each other across a gap G, where the magnetoelectric converting element 8 which converts magnetism into electricity is arranged. Further, interface substrates 5 and 11 equipped with a circuit connected electrically to the magnetoelectric converting element 8 are arranged in the case 1, and the core 7, magnetoelectric converting element 8, and interface substrates 5 and 11 are molded out of a molding material 14. Thus, no ferrite core is used, so the manufacture is easy, the detector is made compact, and damp-proof and water-proof properties, shock resistance, etc., are improved.</p> |
