The wire spring type adapter connector comprises a panel shell, and the panel shell is provided with a transparent mounting hole in which a wire spring contact element is assembled. The wire spring contact element comprises two contacts at the two ends and an elastic part connected between the two contacts. The elastic part comprises spiral springs, the spiral springs of the elastic part at least consist of an inner layer and an outer layer, and at least the spiral spring at the outmost layer is fixedly connected with the corresponding contacts through the two ends. Structurally, the wire spring contact element of the wire spring type adapter connector is actually equivalent to the superposition of a plurality of spiral springs on the same axis. Thus, great elastic force can be provided through a small amount of deformation of the elastic part, the requirement of the spiral springs for materials is reduced, and the manufacture cost of the contact element is lowered. Moreover, the superposed spiral springs unavoidably produce multi-point contact, and the inductance of the contact element can be reduced.
