  • Electromagnetic relay
    Patent number: 6483407
    Abstract: In an electromagnetic relay wherein one of the flanges 2b of the spool 2 is located inside of the opening of the case and a stationary terminal 11 is attached to this spool 2, the problem of dust occurrence due to the attachment of the stationary terminal 11 is solved so as to implement the attachment of the stationary terminal (in particular, a portion to which a stationary contact point 10 is provided) in an excellent condition. In order to achieve this, protruding portions 11e and 11f extending from the stationary terminal 10 are compressively inserted into through holes 2e and 2f configured in the flange 2b and the vicinity of the stationary contact point of the stationary terminal 11 is engaged with the engagement portion 2f formed on the other flange 2a and, thereby, the stationary terminal 11 is attached to this structure.
