【Abstract】Based on the structure of a circular automobile high-voltage connector and the mathematical models of two common elastic beams，thearticlecompares their advantagesanddisadvantages，and designs avarietyof circular contactspring structures，combining factors such as the positive force ofthecontact part，the number ofcontactpoints and the insertionand puling force，and determines acontact spring structure.Finiteelementsimulationof the plugging and puling force and permanentdeformationamount ofcontact spring structure was establishedtodetermine theoptimal inner circle radius Rofthecontactspring，and the influenceoftheinercircleradius Ronthe pluggingand pulling force was analyzed.

【Key Words】 high voltage connector;circular contact spring;simply supported beam;FEM
