摘要： An electromagnetic relay capable of smoothly rotating a movable iron member by eliminating the effect of foreign matters produced on the contact surface of the movable iron piece on a core even if the drive voltage of an electromagnetic block is small. The attracting surface (12) of the movable iron piece (11) is attracted to and separated from the magnetic pole surface (8b) of the core (5) by magnetizing and demagnetizing the electromagnetic block (2) formed by wrapping a coil (7) around the core (5) to open and close a contact by driving a contact block (3). A foreign matter turnout part (13) is formed at at least either of the attraction face (12) of the movable iron piece (11) and the magnetic pole surface (8b) of the core (17).

摘要： An electromagnetic relay is formed by winding a coil around an iron core via a spool, and is structured such that a movable contact piece is driven to open and close a contact point by magnetizing and demagnetizing an electromagnet block arranged in a base, causing a movable iron piece to be attracted and repelled to and from a magnetic pole portion of the iron core to rotate the movable iron piece, and causing a card to reciprocate. The card is guided by the base in a freely reciprocating manner, and includes a runout portion in which one collar portion of the spool of the electromagnet block arranged in the base is movable and a guide portion for holding one end portion of the movable iron piece. The spool includes a cylindrical trunk portion around which the coil is wound and collar portions formed respectively on both ends of the trunk portion, one of the collar portions including a step portion for avoiding interference with an adjacent position to the runout portion of the guide portion when the card reciprocates.

摘要： An electromagnetic relay includes an electromagnetic block formed by winding a coil around an iron core and a frame shaped card. One end portion of the frame-shaped card is engaged with a movable iron piece that is rotated by being attracted to and separated from a magnetic pole portion of the iron core based on excitation and non-excitation of the electromagnetic block. The electromagnetic relay also includes a contact mechanism portion configured to be driven by the other end portion of the frame-shaped card that makes a reciprocating movement so as to open/close contacts and a pair of protrusions protrusively provided on the same shaft center inside of the one end portion of the frame-shaped card. Both side edge portions of the movable iron piece are held by the one end portion of the card and the protrusions. An adjustment opening is provided between the pair of protrusions.
