摘要:
A sensor module includes a sensor, a cover, and a wiring unit. The cover holds the sensor and includes a connector configured to make a connection with an external device. The wiring unit is held by the cover, is arranged from the connector to the sensor, and includes a connecting member extending from the connector to a central region of the cover in its width direction, which is perpendicular to the central line, and a wiring member extending from the central region of the cover in its width direction to a vicinity of the sensor. The cover and connecting member are integrally formed from a mold material. The connecting member includes a first connecting terminal exposed from a surface of the mold material at the central region of the cover in its width direction. The wiring member includes a second connecting terminal conductively joined to the first connecting terminal.

A movement detection unit detects a movement of a detected object and outputs a voltage signal to an electronic control unit. A buffer unit implements buffer amplification on the outputted voltage signal. A pull-up resistor element or a pull-down resistor element is connected with the buffer unit via a wiring portion. A current detection unit detects a direction of an electric current flowing through the wiring portion to output a safe specific voltage signal to the electronic control unit on disconnection of the wiring portion. A power-supply-voltage detection unit detects decrease in a power supply voltage applied to the movement detection unit. A voltage switching unit sets the voltage signal, which is outputted to the electronic control unit through the wiring portion, on a high-voltage side or a low-voltage side according to the detected direction of the electric current, on detection of decrease in the power supply voltage.

A rotation angle sensor includes a housing, a detected object, a magnetism generation section, a housing cover, a circuit substrate, a sensing IC, and a resin body. The sensing IC includes a magnetism detection element, a molded body, and leads. The magnetism detection element outputs a signal in accordance with a change in a magnetic field due to a rotation of the detected object. The molded body covers the magnetism detection element. One end portion of each lead is electrically coupled with the magnetism detection element and the other end portion of each lead protrudes from the molded body and is electrically coupled with the circuit substrate. The resin body seals a portion of the molded body located between the magnetism detection element and the housing cover, the leads, and the circuit substrate.

A magnetic sensing surface of a stroke sensor is placed in an angular range between a first imaginary line and a second imaginary line. The first imaginary line is an imaginary line that coincides with a center line between first and second magnets of a magnetic movable body when a wastegate valve is placed to have a full close degree of the wastegate valve. The second imaginary line is an imaginary line that coincides with the center line between the first and second magnets when the wastegate valve is placed to have a half degree between the full close degree and a full open degree of the wastegate valve.

A rotation angle detecting unit includes an IC package having a magnetism detecting element, a sealing body, and leads; and a covering member having a fixing part and a supporting part, which are integrally formed from resin. The element outputs a signal according to change of a magnetic field generated upon rotation of a magnetism generating device attached to a detection object. The sealing body covers the element. The leads are connected to the element, and project from the sealing body. The fixing part is fixed to a supporting body so that the covering member is attached to the supporting body. The supporting part supports the package such that the element can output the signal. The package is press-fitted into the supporting part after its formation, so that the package is supported by the supporting part with a predetermined pressure applied to part of an outer wall of the sealing body.

A mounting structure for mounting a chip type electric element on a flexible board includes: the flexible board having a first land, on which a first lead terminal of another electric element is soldered; and the chip type electric element having a long side. A whole of the long side of the chip type electric element faces a long side of the first land. A length of the long side of the first land is defined as IA, and a distance between one long side of the first land and one long side of the chip type electric element is defined as IB, the one long side of the first land facing the chip type electric element but opposite to the one long side of the chip type electric element. The length of IA is equal to or larger than the distance of IB.
摘要:
A rotation angle detector is provided with a frame-shaped yoke which includes a first wall and a second wall in parallel. A rotation axis of a detection subject extends inside of the frame-shaped yoke. A magnetic flux vector is uniformed in a direction orthogonal to the first wall, whereby even if a position of a Hall element deviates, the detected magnetic flux density is less varied. A robustness of the detector is enhanced. A distance between the Hall element and a second inner surface of the second wall is shorter than that between the Hall element and a first inner surface of the first wall. A length of the second inner surface is longer than a length of the first inner surface. At a vicinity of the second wall, the area in which the magnetic flux vector is uniformed can be enlarged. Thus, the robustness is further enhanced.
