Abstract
A method for manufacturing an electrical contact pin having a compliant part to be fitted into a plated through hole of a diameter of no more than 0.93 mm (0.037'), which includes the steps of stamping a sheet of metal to form an elongated portion with a rectangular cross section in such a manner that the diagonal length of the elongated portion may be less than said diameter; shearing the elongated portion in its axial direction to form two elongated legs offset to a predetermined extent along a shear plane; pressing said offset elongated legs to flatten so that they return to a plane of the sheet metal and expand outwardly to form a thin slot with a pair of short shear ends left at its opposite ends; and coining the shear ends for fine adjustment of the width of the thin slot so that it may be resiliently fitted into the plated through hole.
