Electromagnetic relay with armature single-side stop

Abstract

The invention relates to an electromagnetic relay with an armature single-side stop. The single-side stop of an armature is achieved through cooperative mounting of a stop groove of a base and a stopblock arranged at one side of the armature. According to the application environment of a relay, stop blocks of the armatures with different structures to regulate the distances between the armaturesand an iron core so as to determine a distance between a moving contact mechanism and a static contact mechanism. In the production process, an armature with a standard specification is generated firstly to optimize cost control. The connection portion of a moving spring is arranged to an I-shaped structure with bilateral symmetry to ensure the balance of the moving spring and perform synchronizeddriving of the armature and the moving contact mechanism under the driving action of the connection portion with the I-shaped structure, the two contacts of the moving contact mechanism are synchronically driven to ensure the contact pressure and ensure the contact reliability. The yielding space for achieving the buffering of the moving spring is formed on the armature, so that double bufferingis achieved, and the effects of reducing or stopping the rebound and bound of the stop block and the moving contact mechanism are reduced or avoided.

Description

technical field [0001] The invention relates to an electromagnetic relay, more specifically, to an electromagnetic relay with one-side stop of an armature. Background technique [0002] Due to the predetermined coil parameters of the electromagnetic relay (such as the wire diameter of the enameled wire, the number of ampere-turns of the coil, the voltage or current of the given coil), whether the suction force generated by the coil and the iron core can make the armature move reliably. In order to ensure the distance between the armature and the iron core surface, it is necessary to stop the armature. Otherwise, under a specific suction force generated by the coil, the distance is too large and the air magnetic resistance is large, and the generated suction force may not be able to drive the armature to the iron core. Core direction action. [0003] Chinese invention patent application 200910260807.8 discloses an electromagnetic relay. A limiting boss is provided on the bas...

Problems solved by technology

[0004] The above-mentioned prior art is to provide a protruding part on the base to limit the position of the armature, but the technical solution of setting the protruding part has the disadvantage that: due to space constraints, the protruding part is relatively too thin and too long, and the base During the injection molding (feeding) or transportation process of parts, the protruding parts are likely to be broken due to the collision between the parts; , then there will be air bubbles or hornet's nests inside the protruding part, which will reduce the strength of the protruding part and cause it to break easily during work
