Abstract
An electromagnetic relay having a return pole piece, a substantially L-shaped armature and an elongated mounting spring for clamping the armature to the return pole piece. The corner portion of the armature is supported by an upper edge of the return pole piece, and the ends of the mounting spring engage the armature and the return pole piece for providing a clamping force, the line of which passes in close proximity to the supporting edge of the return pole piece to produce an armature resetting moment.
Claims7
An electromagnetic relay comprising an armature having a first leg portion, a second leg portion extending at an angle to said first leg portion and a corner portion interconnecting said first and second leg portions, said corner portion having an inner surface and an outer surface, said inner surface having means forming a mounting edge and said outer surface having means forming a recess, a return pole piece having an outer surface disposed adjacent said second leg portion of said armature, an inner surface and means forming a supporting edge for receiving said mounting edge of said armature and for supporting said armature for pivotal movement, said second leg of said armature having means forming an aperture therein, and an elongated curved mounting spring for clamping said armature to said return pole piece and having a first end portion abutting said corner portion of said armature in said recess, a middle portion extending through said aperture and a second end portion disposed in spaced relation to said first end portion and abutting said return pole piece on said inner surface for biasing said mounting edge of said armature into abutting engagement with said supporting edge of said return pole piece, said mounting edge of said armature and said supporting edge of said return pole piece residing substantially between said first and second leg portions of said mounting spring.
