Electro-magnetic relay
The relay exhibits a coil body on whose one flange an armature retaining element is integrated over elastic stays. A bar-shaped armature is secured in the frame-like armature retaining element, whereby the elastic flexural stays serve as a bearing for the armature. Additional fastening parts for the armature are thereby eliminated. A friction-free armature seating also thereby derives.
CROSS-REFERENCE TO RELATED APPLICATION
Application, Hill Firm Case No. P-82, 2108, inventor Erwin Mueller, has subject matter related to the instant application.
BACKGROUND OF THE INVENTION
The invention relates to an electro-magnetic relay having an elongated armature which extends essentially parallel to the axis of the excitation coil and which is pivotably seated with one end at a flange of the coil body, particularly according to German patent application P 31 32 , corresponding to . Ser. No. 401,236, incorporated herein by reference.
The relay according to the aforementioned reference has the advantage that, as a result of directly fastening the springy contact arms in the insulating carrier of the armature, the armature motion is directly transmitted to the springy contact arms so that no actuation slide is required. Due to the connection of the movable springy contact arms to the insulating carrier, thus any and all friction between the armature and movable contact spring arm which would otherwise be caused by a standard actuation slide is avoided. However, all friction is not avoided in the sample embodiments of the aforementioned reference since the knife-edge bearings and trunion mountings of the armature disclosed there cause admittedly slight but not negligible friction.
SUMMARY OF THE INVENTION
An object of the invention is to improve a relay of the type initially cited, particularly according to the aforementioned reference, such that the armature is seated practically
