Claims

[Claims for Utility Model Registration] 1. A coil assembly formed by arranging a permanent magnet in the center of a U-shaped iron core around which a coil is wound, and the coil assembly having its own ends facing both ends of the iron core. a hinge spring portion that supports a tilting motion in which an armature disposed in the armature and both ends of the armature contact and separate from each other between both ends of the iron core; and a movable contact spring that is interlocked with the tilting motion of the armature. An armature assembly integrally fixed with an insulator and the coil assembly are disposed in an upper opening, and the armature has a box shape and one end of the permanent magnet serves as a fulcrum for tilting movement of the armature. When the armature assembly is placed in
an insulator base on which a fixed contact terminal having a fixed contact facing the movable contact of the movable contact spring and a neutral terminal connected to one end of the hinge spring portion are implanted; A substantially rectangular box consisting of a box-shaped cover with an open bottom, and a metal plate installed on one of the insulating base or the cover so that the movable contact comes into contact with the movable contact spring after being separated from the fixed contact. An electromagnetic relay characterized by having a shaped heat sink. 2. An electromagnetic relay, wherein the heat sink according to claim 1 has a heat sink structure. 3. An electromagnetic relay characterized in that the heat sink according to claim 1 has a corrugated or cylindrical portion with a large surface area.
