Abstract:

This paper analyses and calculates the relationship between the spring band’s radial deformation and radial force based on the theory of pure bending.The relationship between the button contacts’s radial deformation and radial force is analyzed on the same principle.The radial forces caused by elastic deformation of spring hoop and button contact are calculated respectively.The results show that the contact pressure of the contact is mainly provided by the spring hoop.And the elastic deformation force of spring hoop is tested by the finite element analysis software.The results provide a theoretical basis for the further application of spring hoop in electrical connection.

Key words: spring hoop, radial deformation, radial force, pure bending, elastic deformation, button contact
