Claims

[Claims for Utility Model Registration] 1. A coil assembly in which a permanent magnet is arranged in the center of a coil spool on which a coil is wound and a U-shaped core is attached, and both ends thereof are opposed to both ends of the U-shaped core. an armature disposed in the armature; a hinge spring that supports a tilting motion in which both ends of the armature come into contact with and separate from both ends of the U-shaped iron core; and a movable contact at the tip that is linked to the tilting motion of the armature. an armature assembly in which a movable contact spring having a movable contact spring and a movable contact spring are integrally fixed with an insulating fixed body; and the coil assembly is disposed in a box-shaped opening, and one end of the permanent magnet serves as a fulcrum of tilting movement of the armature. When the armature assembly is arranged so that the movable contact of the movable contact spring faces the fixed contact, a fixed contact terminal, a neutral terminal connected to one end of the hinge spring, and a coil lead-out terminal are implanted. a substantially rectangular insulating base that is parallel to the movable contact spring and has a length slightly shorter than that of the movable contact spring. An electromagnetic relay characterized in that heat dissipation fans are provided at predetermined intervals, and a protrusion is provided at a longitudinally intermediate position of the heat dissipation fans on the back surface of the ceiling portion of the cover. 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. 3. The electromagnetic relay according to claim 1, wherein the heat dissipation fan provided on the insulating fixed body of the armature assembly is formed of a thin metal plate.
