Magnet system for an electromagnetic relay

摘要

An electromagnetic relay has an angled yoke affixed to a first end of a magnetizable coil core and extending parallel to said core to an end spaced radially adjacant an opposite end of the core. An armature is pivotally supported upon the free end of the yoke for movement toward and away from said opposite end of the core. The yoke is formed with a recess or slot in its free end which engages a lateral projection from a flange affixed about said opposite end of the core. The projection cooperates with the yoke recess to fix the free end of the yoke in lateral and radial position with respect to the core. The projection and recess align the yoke in position parallel to the core during assembly of the relay, assuring good magnetic contact beween the core and the yoke at the point of attachment. The recess and projection also reinforce the assembly against mechanical displacement of the yoke during service with consequent breaking or impairment of the magnetic circuit connection.
