To make the design and manufacture of the spring contact more standardized, the text analyzed the characteristics of the spring contacts detailedly, and introduced the contact resistance, conductivity and structure design of the CuCo2Be contact spring. The conclusions have some significance in design, manufacture, operation and maintenance of CuCo2Be contact spring.

This article is to introduce all kinds of phenomenon of spring contact damage when spring contact and neighbouring parts are incorrect designed, and to give preventive design method of spring contact damage which will guide to correct design and use spring contact. For instance, to avoid contact of two neighbouring rings of spring contact, especially in working condition, plug-in tip should have good guiding design. The deformation of spring contact and its neighbouring part should not occurr during work condition.
