Abstract: A conductive contact base, comprising a conductive component, an elastic component, and a contact surface is described in which the conductive component is clamped by the elastic component, the conductive component opens and closes freely within an elastic limit whereby accommodating plugs with different sizes, and the contact surface is disposed between the conductive component and the elastic component. The conductive contact base of the invention has the advantages of a large contact surface, strong clamping force, good impact resistance, good vibration resistance, and good deformation resistance.
