Claims

[Scope of utility model registration request]

A coil assembly including a permanent magnet arranged in the center of a spool having a U-shaped iron core penetrated through the center and a coil wound thereon; An armature disposed on the upper part of the coil assembly, a movable contact spring that is interlocked with the tilting movement of the armature, and a tilting movement that allows both ends of the armature to come into contact with and separate from each other between both ends of the iron core. an armature assembly consisting of an insulating fixing body that integrally fixes a hinge spring; the armature assembly has a box shape with an open top, the coil assembly is housed in the opening, and one end of the permanent magnet is connected to the contact When the armature assembly is arranged to serve as a fulcrum for the tilting movement of the pole, 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 installed. An electromagnetic relay comprising an insulator base and a cover that covers the coil assembly and armature assembly from above the insulator base, the cover being parallel to the movable contact spring and extending from the movable contact spring. The insulating fixed body is provided with a lifter made of a shape memory alloy that has a rectangular shape with a shorter length and is curved toward the opposing movable contact spring side when heated, but returns to its original state when cooled. An electromagnetic relay featuring:
