Movable spring armature component and clapper relay thereof

Abstract

The invention discloses a movable spring armature component and a clapper relay thereof. The movable spring armature component comprises an armature, an injection molding part and a movable spring, wherein an upper part of the armature is provided with a matching part which is matched with a knife edge of a yoke of a magnetic circuit part of the relay, and one surface of the armature can be matched with a pole surface of an iron core of the magnetic circuit part of the relay through matching with the yoke; two sides of the armature are respectively provided with a bending part which is bent towards the direction deviating from one surface of the armature, and the injection molding piece is coated on the other surface and the side surface of the armature and completely coated on the bendingparts so as to be stably combined with the armature. The movable spring armature component provided by the invention has the characteristics of small component size, simple production and assembly, convenient realization of automatic production, small influence of accumulated assembly tolerance among multiple groups of movable springs, and good parameter consistency of batch production of finished relays.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a spring armature part and a snap-on relay. Background technique [0002] The snap-in relay usually includes a moving spring armature part. The moving spring armature part is to assemble the moving spring and the armature together. Through the cooperation between the armature and the iron core pole surface of the magnetic circuit part, the moving reed is driven to move, so that the moving reed moves The contact is in contact with the normally open static contact of the normally open static spring and / or is separated from the normally closed static contact of the normally closed static spring. A moving spring armature component in the prior art, in order to realize the pressure-resistant isolation between the moving spring and the armature, a plastic part for pressure-resistant isolation is arranged between the moving spring and the armature. figure 1 Be the structural exploded sc...

AI Technical Summary

Problems solved by technology

[0003] 1. The armature, moving spring, moving spring support and clamping block all need to leave a through hole position for the rivet to pass through in the structure, resulting in a large volume of each component, which also results in a large volume of the entire moving spring armature component. It is not conducive to the miniaturization of relay products;

[0004] 2. The armature, moving spring, moving spring support, and clamping block need to be put together and then riveted, that is, multiple parts need to be riveted together, and the positioning is complicated during assembly, which is not suitable for automatic production

[0005] 3. The moving spring armature parts of this structure are usually used in multiple sets of moving springs, and the multi-set moving springs will be affected by the cumulative tolerance of assembly, resulting in a large difference in the flatness of the moving springs, which will affect the parameters of mass production of products consistency
