PURPOSE: A fish shaped plate spring connection pin is provided to remarkably reduce manufacturing costs by forming an outer tube, a coil spring, and a top-down contact part and improving the workability. CONSTITUTION: A cubic type connection pin is manufactured by using blanking, sheering, and bending. An upper contact part includes two plates which are facing each other. Two semi-ellipse shaped plate springs are located in the center of the connection pin. A lower contact part is formed in a part where two semi-ellipse shaped plate springs are contact in the lower part. Composed all components are integrally connected. The upper contact part includes two plates which are facing each other. The upper part of the plate is composed of at least one thread in order to be stable the contact.
