ABSTRACT:
A magnetic circuit for a miniature relay comprising a coil carried by a magnetic frame and an armature adapted for movement in response to energization of the coil to close an air gap between the armature and a pole face of the frame. A portion of the frame comprising a pair of supporting legs is sufficiently close to a core face portion of the frame to define a fringing flux path tending to divert flux from the useful flux path including the armature, air gap and frame. A barrier is provided in the fringing flux path of a material creating sufficient reluctance in that path to resist flux flow therethrough thereby increasing flux flow in the useful flux path to increase relay efficiency. The barrier can comprise non-magnetic material in the supporting legs, in the core face or in both. A method of making the frame includes forming a bi-metal strip including a center magnetic iron section and two side non-magnetic stainless steel sections welded thereto and then forming the desired frame configuration and shape by stamping and bending.
