Claims

[Claims for Utility Model Registration] 1. A coil assembly comprising a spool around which a coil is wound, a U-shaped iron core penetrated through the center of the spool, and a permanent magnet disposed in the center of the U-shaped iron core; An armature arranged such that both ends thereof face both ends of the iron core, a hinge spring that supports a tilting movement in which both ends of the armature contact and separate from both ends of the iron core, and tilting of the armature. An armature assembly in which a movable contact spring linked to movement is integrally fixed with an insulating fixing body, and a box-shaped opening at the top,
When the coil assembly is disposed in the opening and the armature assembly is disposed such that one end of the permanent magnet serves as a fulcrum for tilting movement of the armature, a fixed member of the movable contact spring that faces the movable contact of the movable contact spring An electromagnetic relay comprising a fixed contact terminal having a contact, a coil lead-out terminal, and an insulator base on which a neutral terminal connected to one end of the hinge spring portion is planted, in which the movable contact spring is parallel to the movable contact spring. A thin heat dissipating plate made of a metal material having approximately the same area as is provided on the insulating fixed body of the armature assembly at a predetermined interval, and a protrusion is provided near the movable contact on the back surface of the ceiling portion of the cover. An electromagnetic relay characterized in that the movable contact spring and the heat dissipating thin plate come into contact at the position of the protrusion after the contacts are separated. 2. The electromagnetic relay according to claim 1, wherein the protrusion provided on the back surface of the ceiling portion of the cover is a peak-like protrusion.
