Abstract:
An electromagnetic relay comprising an insulation base and an armature block, said insulation base comprising:a fixed-side terminal set including fixed contacts, a U-shape iron core whose middle portion is wound by a coil, a permanent magnet which is inserted and engaged between side-end portions of the U-shape iron core, and a fixed-side insulator which integrally holds the fixed-side terminal set, the U-shape iron core and the permanent magnet together, said armature block comprising: a moving-side terminal set including moving contacts, an armature which is placed opposite to the side-end portions of the U-shape iron core, and a moving-side insulator which integrally holds the moving-side terminal set and the armature together, so that the armature block is supported by the insulation base to pivotally move on the permanent magnet, wherein the fixed-side terminal set, the U-shape iron core and the permanent magnet are fixed to the fixed-side insulator by its integral molding, wherein a contact fixing portion is formed with the fixed-side insulator, the contact fixing portion being integrally molded with the fixed-side insulator to fix the permanent magnet and the U-shape iron core together where the permanent magnet is placed in contact with the side-end portions of the U-shape iron core, and wherein channels are formed on an upper surface of the permanent magnet to face with the armature block, and the contact fixing portion is partly extended to form engagement portions that partly engage with the channels of the permanent magnet.
