  • Knock sensor
    Patent number: 7449819
    Abstract: A knock sensor includes: a base including an annular flange portion and a cylindrical portion, an annular piezoelectric element fitted onto the cylindrical portion, electrode portions oppositely formed on front and rear surfaces of the annular piezoelectric element, first and second terminal plates in contact with the electrode portions, an annular weight, a first insulating sheet interposed between the first terminal plate and the flange portion, a second insulating sheet interposed between the second terminal plate and the weight. The electrode portions include annular partial electrodes each having a width narrower than a radial width of the piezoelectric element. The annular partial electrode has a thickness d satisfying: L/d<80 where L is a radial dimension of outer circumferences of the front and rear surfaces where the electrode portions are not arranged.
    Type: Grant
    Filed: December 26, 2006
    Date of Patent: November 11, 2008
    Assignee: Mitsubishi Electric Corporation
    Inventors: Souichi Satou, Harumasa Shibata, Akito Yokoi, Koji Tanimoto
