Electromagnetic relay

摘要

An electromagnetic relay in which an asymmetrically-shaped armature (6) is tiltingly mounted about a U-shaped magnetic yoke structure (15) and pivoting about two shoulder lateral surfaces on one arm (15a) of the magnetic yoke. The tilting mechanism allows the mechanical friction generated during relay reclosings to be directed to the lateral surfaces and prolongs the life of the relay. A permanent magnet is incorporated in an interior location of the U-shaped magnetic yoke and attached to one arm of the yoke, in a position near and parallel to the bottom centre arm of the U-shape. A support clamp (7) is mounted on one arm of the magnetic yoke to support the armature in its tilting position. A mechanical damper in the form of a sheet cover is mounted over the armature to transfer the stress associated with the reclosing of relay circuit away from the polar contact surfaces. A flap cover is provided to facilitate the assembly of the relay resetting mechanism (21) in the form of a pivot, allowing the pivot to be inserted through an aperture in the flap cover, and the whole flap assembly is snap-fittingly mounted on the relay. <IMAGE>
