VANE STOP ASSEMBLY FOR VANE-TYPE RELAY

摘要

An integral vane stop assembly for installation within the throat of a vane of a vane-type relay as a single unit while adhering to the precise tolerances necessary to maintain the vane bearings in the required alignment. The vane stop assembly includes a shaft; a pair of retainer bushings mounted on the shaft; and a resilient stop member mounted on the shaft and interposed the pair of retainer bushings. The shaft has a pair of circumferential grooves formed therein for retaining a pair of retainer bushings having a circumferential protrusion formed on an inner surface thereof. A vane-type relay including a base; at least one contact assembly mounted on the base for selectively providing one of an open and a closed circuit; a vane assembly operatively connected to the contact assembly, the vane assembly having a throat portion formed therein; a pair of legs mounted on the base for pivotably supporting the vane assembly; a coil electrically connected to a control circuit for moving the vane assembly in response to a change in current in the coil; and an integral vane stop assembly attached to the pair of legs and configured to extend through the throat portion of the vane assembly to discontinue a pivot motion of the vane assembly at a predetermined location. A method of manufacturing a vane stop assembly for a vane-type relay including the steps of forming a shaft which is configured and dimensioned to precisely fit between a pair of vane assembly support legs for the vane-type relay; press-fitting a pair of retainer bushings, having a longitudinal bore therein, on the shaft; and mounting a resilient stop member on the shaft between the pair of retainer bushings.
