Current detecting apparatus

A current detecting apparatus comprising:

• a magnetic core formed of a magnetic material, the magnetic core including two ends facing each other via a gap between the two ends and being formed continuously so as to surround a hollow portion;
• a magnetoelectric device including:
• a magnetism detecting portion arranged in the gap, and
• a first lead terminal extending from the magnetism detecting portion,
• the magnetoelectric device being configured to detect a magnetic flux that varies with electric current passing through the hollow portion;
• a connector having a body and a second lead terminal extending from the body;
• a circuit board to which the first lead terminal and the second lead terminal are secured, and to which the body is fixed;
• and
• a housing including a container and a lid to be combined with the container, the container and the lid each being formed of an integrally molded member of a resin material having insulating properties, and the container being configured to accommodate and support the magnetic core, the magnetoelectric device, and the circuit board in a certain positional relationship, wherein:
• the container includes
• an element supporting portion that forms a depression in which the magnetism detecting portion is fitted at the gap,
• a connector supporting portion that positions the body, by a fitting structure, in three directions orthogonal to each other including a first direction in which the second lead terminal extends in parallel to the first lead terminal, and
• a substrate fixing portion where the circuit board is fixed at one point;
• the body includes four side surfaces and a plurality of projections that project from a first side surface of the four side surfaces, the first side surface facing such that the first side surface is approximately perpendicular to the first direction, and the projecting portions contacting a top of the circuit board;
• and
• the connector supporting portion includes
• a pair of first connector restricting portions that contact a second side surface and a third side surface of the four side surfaces, the second side surface and the third side surface being located on two sides of the first side surface, and that restrict a movement of the body in a second direction orthogonal to the first direction,
• a second connector restricting portion that contacts a fourth side surface of the four side surfaces, the fourth side surface being opposite the first side surface, and that restricts the movement of the body in a direction opposite to the first direction, and
• third connector restricting portions that protrude from opposing surfaces of the pair of first connector restricting portions, that are disposed between the plurality of projecting portions, that contact side surfaces of the plurality of projecting portions, that contact the first side surface, and that restrict the movement of the body portion in the first direction and in a third direction orthogonal to the first direction and the second direction.
