ABSTRACT:
An electromagnetic relay includes a casing, and a relay core member sealed in the casing and including an electromagnetic unit and a terminal unit. The electromagnetic unit includes a spool frame set having an engagement portion, a coil unit wound on the spool frame set, and a pair of coil winding pins. Each of the coil winding pins has a conductive portion exposed from one of opposite first sides of the spool frame set, and a coil winding portion extending along one of opposite second sides of the spool frame set. The terminal unit includes an engaging block having an engagement portion connected to the engagement portion of the spool frame set for preventing separation of the terminal unit from the electromagnetic unit, a terminal set, and an armature component.
