PURPOSE: A phi spring and a connecting pin are provided to minimize electric resistance and the loss of signals by using metal as an elastic body. CONSTITUTION: A phi spring is formed into a circular shape. One upper end of the circular shape is expanded to the upper and the lower side to form an upper probe part. The other end of the circular shape passes through the center part of the circular shape in order to form a lower probe part. A contact(101) of the upper probe part and the lower probe part is maintained. In case the application of force toward the upper and the lower sides, the phi spring is displaced and provides elastic force.
