Shockproof relay

Abstract

The invention relates to an electromagnetic relay and particularly relates to a shockproof relay, which belongs to the technical field of electrical equipment. The shockproof relay comprises a yoke, an armature, an elastic piece and a push rod, wherein armature riveting holes in a reversed L-shaped elastic piece vertical section are in matched and fixed riveting with elastic piece riveting terminals of the armature; blocks at the tail part of the vertical section abut against block grooves at an elastic piece connection end of the push rod; clamping blocks of the armature terminal are clampedand inserted in clamping grooves in the push rod; the elastic piece horizontal section is fixed and matched with the L-shaped yoke horizontal section; an elastic piece mounting table of the yoke is nested in a yoke mounting hole in the elastic piece; elastic piece clamping blocks of the yoke are clamped and inserted in buckling loops of the elastic piece; and a pair of elastic piece supporting tables which abut against the surface of the elastic piece is arranged near the yoke blade and on the outer wall of the yoke. According to the shockproof relay in the invention, serial movement does nothappen to the yoke or the armature in a shock working condition, the yoke blade and the armature blade are constantly contacted together, the product stability is good, and automatic assembly can be realized easily.

Description

technical field [0001] The invention relates to a small electromagnetic relay, in particular to an anti-shock relay, and belongs to the technical field of electrical equipment. Background technique [0002] Electromagnetic relay is a kind of relay that uses electromagnetic force to drive the relative movement of mechanical parts to produce a predetermined response. It is generally composed of iron core, coil, armature, yoke, shrapnel, push rod, and dynamic and static reed with contacts. When the current passes through the coil, an electromagnetic force is generated, and the armature is attracted, so that the moving contact of the moving reed is in contact with the static contact of the static reed; when the current in the coil disappears, the electromagnetic force disappears, and the armature resets, thus The moving contact of the moving reed is separated from the static contact of the static reed, and the purpose of conducting or cutting off the circuit is achieved through ...

AI Technical Summary

Problems solved by technology

[0003] Existing relays often have relay parameter variation in a vibration environment, mainly because the vibration causes the yoke or armature to move back and forth, and the blade of the yoke and the blade of the armature are in poor contact, causing parameter variation, decreased working stability, and reduced working life of the relay; In the actual production and assembly process, the connection of the traditional relay yoke, armature and shrapnel is mainly through spot welding or riveting. The production process is complicated, the product quality is not stable, the product consistency is poor, and the production cost is relatively high. And it is inconvenient to realize automatic assembly
