ELECTROMAGNETIC RELAY

摘要

ELECTROMAGNETIC RELAY An electromagnetic relay is described comprising within its coil bobbin a magnet core the ends of which extend substantially at right angles to the longitudinal axis of the bobbin so as to form pole shoes projecting from the coil bobbin and having mutually aligned pole faces and further comprising an armature which is disposed externally of the coil bobbin between the pole shoes of said magnet core and which is pivotally mounted for rotation about one of its centroid axes, the axis extending perpendicularly to longitudinal axis of the bobbin. According to the novel features contact terminals disposed on both sides of the longitudinal axis of the coil are positively located by being embedded in a contact carrier means. The coil bobbin and the contact carrier means extending substantially over the entire length of the coil bobbin, are provided with engaging means for mutual positioning and retaining of the contact carrier means and the coil bobbin. The contact terminals have associated therewith prelocated contact springs arranged within the relay, the forces exerted by the contact springs interacting through the armature, and bearing means for the armature are provided substantially centrally of the coil between the pole shoes.
