Patent ID: 7924123

Claim:
A method for adjusting an electromagnetic relay, the electromagnetic relay comprising 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, the method comprising: inserting a restoring spring in an axial hole of the solenoid, slidably inserting the movable iron core of the movable contact-point block into the axial hole of the solenoid from thereabove, inserting the fixed iron core into the axial hole from therebelow, adapting the movable iron core to slide 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, which effects contacting and separating of a movable contact point provided on the movable contact piece with and from a fixed contact point, pushing the movable contact-point block to bring the movable iron core into contact with the fixed iron core against the spring force of the restoring spring, bringing the movable contact point on the movable contact piece into contact with the fixed contact point, pushing in the movable contact-point block by an amount corresponding to a predetermined amount of contact-point follow against the spring force of the contact pressing spring to position the fixed iron core on the yoke through the movable iron core, and securing the fixed iron core and the yoke to and integrated with each other.
