Abstract (en)

[origin: EP2003671A2] In order to provide an electromagnetic relay in which mold manufacturing and assembling work are easy, the electromagnetic relay comprises: a base 10; an electromagnetic block 20 mounted on the base 10, in which one end portion of an iron core 30 around which a coil 21 is wound serves as a magnetic pole portion 31, and the other end portion 32 is caulk-fixed to an L-shaped yoke 40; a movable iron piece 50 rotatably supported on the yoke 40 through an L-shaped hinge spring 60, whose horizontal portion 61 is inserted between an upper surface of the base 10 and a bottom surface of the yoke 40, and facing the magnetic pole portion 31 of the iron core 30 so as to be able to be contacted with and separated from the magnetic pole portion 31 of the iron core 30; and a card 80 making a reciprocating movement based on rotation of the movable iron piece 50; and a contact mechanism portion 70 formed on the base 10 and driven by the card 80. Positioning ribs 62 formed by respectively cutting and raising both side edge portions of the horizontal portion 61 of the hinge spring 60 are each provided with an elastic pawl portion 62a locked to the spool 22 so as to prevent the hinge spring 60 from coming off.
