Abstract:
1. An electromagnetic relay comprising: a casing; and a relay core member sealed in said casing, said relay core member including an electromagnetic unit adapted for generating an electromagnetic field, said electromagnetic unit including a spool frame set that includes a pair of opposite first sides and a pair of opposite second sides, a coil unit wound on said spool frame set, and a pair of coil winding pins, each of said coil winding pins having a conductive portion exposed from one of said first sides and a coil winding portion extending along one of said second sides, said spool frame set further including an engagement portion and a pair of mounting frames, each of said mounting frames being disposed at and extending along a respective one of said first sides of said spool frame set, and being formed with a pair of through holes formed through a corresponding one of said mounting frames and spaced apart from each other, each of said conductive portions including a horizontal section being exposed from one of said mounting frames and a vertical section extending into a corresponding one of said through holes, and a terminal unit that includes an engaging block including an engagement portion connected to said engagement portion of said spool frame set of said electromagnetic unit for preventing separation of said terminal unit from said electromagnetic unit, a terminal set exposed from said casing, and an armature component being affected by the electromagnetic field generated by said electromagnetic unit and serving as a switch mechanism by cooperating with said terminal set.
