Abstract

Abstract:

The spring components of electromagnetic relays play a vital role in its electrical performance.In this paper,the relationship between contact force,contact position,contact area,sliding distance and the travel of push rod (or armature) is obtained by finite element simulation,and the relationship between circuit resistance,contact resistance and contact force is further analyzed.Finally,the electrical contact performances of different types of flexible spring components are compared and analyzed.

Key words: electromagnetic relay, flexible spring component, electrical contact, finite element simulation
