A connecting structure of a movable reed of a relay and a lead-out terminal

Abstract

The invention discloses a connecting structure of a movable reed and a lead-out end of a relay, comprising a movable reed, a lead-out end and a connecting piece. The connecting piece is connected between the tail part of the movable spring and the lead-out end; The connecting piece is a plurality of conductive metal pieces formed by bending. As that function of the movable spring part is decomposed, the anti-mechanical fatigue characteristic of the movable spring part are stripped out, so that only the connecting structure of the movable part is deformed during the free stroke, and the movablespring is deformed only during the over-stroke stage; At the same time, by optimizing the design of the connection structure, the deformation of the connection structure in the movement process can be reduced, so as to reduce the demand of the mechanical fatigue resistance. Finally, the product has the characteristics of compact structure, strong carrying capacity, easy adjustment of overtravel,avoidance of foreign body pollution and mass production.

Description

Technical field [0001] The present invention relates to the technical field of relays, in particular to a connection structure between a moving spring and a leading end of a relay. Background technique [0002] The existing electromagnetic relay generally includes a magnetic circuit part, a contact part and a moving part. The magnetic circuit part includes coils (including skeleton and windings), yokes, armatures, permanent magnets and magnetic sheets. The contact part includes a moving spring component and a static spring component; the moving spring component is composed of a moving spring part (including a moving reed and a contact) and a leading end. The moving part is generally a push block or an armature assembly; the armature assembly is generally formed by a moving spring part and an armature through an insert injection molding method. The magnetic circuit part and the contact part are assembled to form a complete relay piece, and then the contact is opened and closed t...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a connection structure between the moving reed and the lead-out end of the relay. By decomposing the function of the moving spring part, the anti-mechanical fatigue characteristics are stripped out, so that the moving part can move freely. Only the connection structure deforms during the stroke, while the moving reed is deformed only in the over-stroke stage; at the same time, through the optimal design of the connection structure, the deformation of the connection structure during the movement of the moving part is reduced to reduce its resistance to stress. The demand for mechanical fatigue characteristics; finally, the product has the characteristics of compact structure, strong load capacity, easy adjustment of overtravel, free from foreign matter pollution and mass production
