  • Method and system for adjusting an electromagnetic relay
    Patent number: 7924123
    Abstract: An electromagnetic relay has a solenoid formed from a wound coil, a movable contact-point block having a movable iron core, an insulation holder integrated with the upper end portion of the movable iron core and a movable contact piece which is biased toward and supported by the insulation holder through a contact pressing spring, and a fixed iron core fitted in a through hole in a yoke. A restoring spring is inserted into an axial hole of the solenoid. The movable iron core of the movable contact-point block is slidably inserted into the axial hole of the solenoid from thereabove. The fixed iron core is inserted into the axial hole from therebelow. The movable iron core is adapted to be slid into the axial hole based on the magnetization force and the demagnetization of the coil to move the movable contact-point block back and forth.

  • Electromagnetic relay
    Patent number: 7911301
    Abstract: An electromagnetic relay has a solenoid formed from a wound coil, a movable iron core that is reciprocated upwardly and downwardly in an axial hole of the solenoid, and a movable contact point that reciprocates together with the movable iron core. The movable contact point is contacted and separated with and from a fixed contact point for opening and closing a contact point. An arc generated at a time of opening and closing of the contact point is flowed, in a predetermined direction, by the magnetic field of at least a single permanent magnet placed at a side of the fixed contact point and the movable contact point that are contacted and separated with and from each other. Coil terminals are connected to leader lines of the coil, at least at a single side of the flow of the arc.
