  • Patent number: 8529303
    Abstract: The present invention provides a spring contact for conducting electricity, Among two side edges for conducting electricity at a cross section of each ring of the spring contact, wherein one side edge for conducting electricity has two or more contacting points, while the other side edge for conducting electricity having at least one contacting point, or a contacting line. Because at each ring cross section of the spring contact, two or more than two contacting points are secured on any side edge for conducting electricity, aim of duplicated current passing capacity is obtained. The shape of each ring cross section is changed from annular shape to other shapes whose cross section area is smaller than that of the annular shape. Therefore, the spring contact of present invention which satisfying the requirements for miniaturizing, saves materials and reduces working space occupied during its installing.
