Publication number: 20250246841Abstract: A connector includes a housing including a cavity extending in a first direction, a terminal and a retainer. The housing is formed with a locking lance resiliently deformable in a second direction orthogonal to the first direction. The retainer includes two lock pieces, a restricting portion and a rib extending from the restricting portion. The restricting portion is disposed at a position deviated in the second direction from the center plane CP. The locking lance interferes with the terminal and is resiliently deformed toward the center plane CP in the second direction in the process of inserting the terminal into the cavity. The two lock pieces interfere with the housing and are resiliently deformed away from the center plane CP in the second direction in the process of moving the retainer from a temporary locking position to a complete locking position.Type: ApplicationFiled: January 15, 2025Publication date: July 31, 2025Inventors: Yusuke HASEGAWA, Yuki KONDO

Publication number: 20190217783Abstract: A rear view mirror assembly can switch the operating mode between a first mode in which the rear view mirror assembly is used as an optical mirror, a second mode in which a first image captured by a camera is displayed on a display screen, and a third mode in which a second image captured by the camera and displayed darker than the first image is displayed on the display screen. An actuator sets the angle of a semitransparent mirror: at a first angle in the first mode; at a second angle greater than the first angle in the second mode; and at a third angle greater than the first angle in the third mode. A controller switches the operating mode of the rear view mirror assembly between the first mode and the third mode based on a signal output from a first light sensor and indicating the illuminance.Type: ApplicationFiled: July 4, 2017Publication date: July 18, 2019Inventors: Yusuke HASEGAWA, Yuji MATSUMOTO
