Abstract:
An electrical pin for solderless insertion into metallized apertures of a circuit board, the pin comprising an elastically deformable press-fit portion, a transition portion connected to the press-fit portion and a positioning portion connected between the transition portion and a tapered end, wherein each of the press-fit portion, transition portion and positioning portion each comprises at least three peripherally spaced contact areas extending substantially along the entire length of the respective portion and being equidistantly spaced from a common longitudinal axis, the contact areas of the press-fit portion being equidistantly spaced from the common longitudinal axis and defining a first diameter which is larger than a diameter of the apertures in the circuit board, the contact areas of the transition portion tapering in a direction toward the positioning portion, and the contact areas of the positioning portion being equidistantly spaced from the common longitudinal axis and defining a second diameter that is smaller than the first diameter, the second diameter being equal to an aperture diameter of the apertures on the circuit board minus a small distance for clearance of the contact areas with sides of the apertures, the press-fit portion comprising a pair of webs and a curved, thin bridge between the pair of webs forming an H-shaped figure, each web having a pair of first rounded outer edges, the first rounded outer edges forming the contact areas of the press-fit portion and the positioning portion comprising a second pair of webs and a connecting bridge between the second pair of webs, the press-fit portion and positioning portion having different cross-sectional shapes.
