摘要： A magnetic permeable member and a current detection device which can detect current in a wide range by a magnetic field detection element at low cost are provided. A magnetic permeable member includes a closed portion and an opened portion. Thus, when the large current flows through a bus bar, the magnetic field is less likely to be strong at the opened portion, thus the large current is easily detectable by a magnetic field detection element arranged at the opened portion. When the small current flows through the bus bar, the magnetic field is more likely to be strong at the closed portion, thus the small current is easily detectable by a magnetic field detection element arranged at the closed portion. Consequently, the magnetic field detection elements can be commonalized to reduce the cost, while allowing the detection of the current in a wide range.

摘要： Provided is a current detection device capable of reducing manufacturing cost. A current detection device 1 includes a plate-like bus bar, a printed circuit board on which a magnetic field detecting element is mounted, a magnetic member, and a housing holding these components. The bus bar can be assembled into the housing by sliding in its longitudinal direction. The housing includes a first rib pressing the bus bar to restrict a movement in a thickness direction of the bus bar, a second rib pressing the bus bar to restrict a movement in a width direction of the bus bar, and a retaining protrusion fitting into a cutout portion provided at both sides in a width direction of the bus bar so as to retain the bus bar in a longitudinal direction of the bus bar.

摘要： A liquid surface level sensor includes a plurality of piece portions provided at both ends of the liquid surface level sensor in a width direction, and a plurality of elastically deformable hook portions formed to elongate from both end sides in a first height direction. A pump holder includes a plurality of claw portions formed in a claw shape by bending front end sides in an intra-width direction of the liquid surface level sensor, and a plurality of convex portions on a side of the first height direction of the plurality of claw portions. A plurality of hook portions is elastically deformed in contact with the plurality of convex portions by sliding the liquid surface level sensor in a second height direction, the plurality of hook portions gets over the plurality of convex portions and restores from an elastically deformed state by further sliding the liquid surface level sensor.

摘要： A sensor housing of a fluid level sensor includes a peripheral wall portion and a lead wire inserting portion. The peripheral wall portion forms a hollow space penetrating in the depth direction of the sensor housing and is formed in a manner of surrounding the periphery of a terminal area of a lead frame. The lead wire inserting portion is formed by notching the peripheral wall portion in the depth direction of the sensor housing. The lead wire inserting portion consists of a first inserting portion into which a lead wire extending from the terminal area is inserted and a second inserting portion into which the lead wire is inserted after passing through the first inserting portion and holds the lead wire in a manner of bending the lead wire in a crank shape. With this configuration, the fluid level sensor can prevent leak current generated on the terminal area and thus can connect a conductive wire (the lead wire) used for connection with an external circuit with the terminal area in good condition.
