摘要： Provided is a rotation angle detection device for an automotive vehicle drive motor. The device includes a magnetic encoder including magnetic tracks with different numbers of magnetic poles. The magnetic tracks form coaxial rings. The device also includes magnetic sensors operable to sense the magnetic fields of the magnetic tracks. The magnetic sensors obtain information on a location within a magnetic pole of the magnetic tracks and generate magnetic field signals indicative of respective phases. The device further includes a phase difference determination unit that determines a difference between the respective phases of the magnetic field signals, an angle computation unit that computes an absolute angle of the magnetic encoder, based on the determined difference, and a signal output unit that outputs the computed absolute angle. The magnetic encoder is associated with an output shaft of the drive motor or with a bearing assembly equipped to the drive motor.

摘要： A case with a connector integrally formed with a resin connector, and can be manufactured with a small number of processes is provided. The connector case includes a housing, a resin connector, and a ground terminal extending along an outer periphery of the connector. A terminal-side fixing portion extending backward from the ground terminal is crimped to or pressed over a housing-side fixing portion. When molds are closed after the housing and the ground terminal are placed in the molds for injection molding of the resin connector, a pressing portion formed on the mold presses the terminal-side fixing portion against the housing-side fixing portion to crimp or press the terminal-side fixing portion to or over the housing-side fixing portion. As a result, in the process for the injection molding of the connector, the ground terminal is fixed to the housing at the same time. The connector case with the ground terminal fixed to the housing can be manufactured in a small number of processes.
