Abstract

A shield element for a vacuum interrupter for installation between an electrically conductive wall element and an electrically insulating wall element of a vacuum interrupter includes a connection region, a shield inner region and a shield outer region. The shield outer region can be disposed outside of and the shield inner region can be disposed within the vacuum interrupter. The connection region has a first structure and a second structure which prevent the formation of mechanical stresses after soldering of the vacuum interrupter. A vacuum interrupter, a method for producing a shield element and a method for producing a vacuum interrupter are also provided.
