  • Electromagnetic relay
    Patent number: 10943753
    Abstract: According to one or more embodiments, when a predetermined time has passed after generation of an arc at least either between a movable contact and a fixed contact or between a movable contact and a fixed contact, an arc generated between the movable contact and the fixed contact is extended by a magnetic field generation unit to be longer than an arc generated between the movable contact and the fixed contact.
    Type: Grant
    Filed: November 29, 2018
    Date of Patent: March 9, 2021
    Assignee: OMRON Corporation
    Inventors: Syuichi Itoda, Masayuki Noda, Koji Takami, Takeshi Nishida, Yasuo Hayashida, Keisuke Yano, Ayaka Miyake
  • Electromagnetic relay
    Patent number: 10312044
    Abstract: An electromagnetic relay includes a base, an electromagnetic block disposed on an upper surface of the base, a movable iron piece that rotates based on excitation/non-excitation of the electromagnetic block, a movable contact piece that rotates integrally with the movable iron piece, a movable contact fixed to a free end of the movable contact piece, a fixed contact disposed so as to come into or out of contact with the movable contact in association with rotation of the movable contact piece, and a magnetic field generation unit disposed so as to attract an arc generated between the movable contact and the fixed contact in a direction that, as seen from the fixed contact, is opposite to the movable contact and the base.

  • Electromagnetic relay
    Patent number: 10176952
    Abstract: Provided is an electromagnetic relay that is reduced in size and has great flexibility in designing. For this purpose, when a predetermined time has passed after generation of an arc at least either between a movable contact and a fixed contact or between a movable contact and a fixed contact, an arc generated between the movable contact and the fixed contact is extended by a magnetic field generation unit to be longer than an arc generated between the movable contact and the fixed contact.
