Contact pin for pressing into a printed circuit board and contact arrangement

An electrically conductive contact pin for press-fitting along a press-fit direction into a through-hole of a printed circuit board,

• wherein the press-fit direction of the contact pin is defined as a Z-direction, perpendicular to the Z-direction, an X-direction is defined, and perpendicular to the Z-direction and the X-direction, a Y-direction is defined,
• wherein the contact pin comprises a crimp zone, the crimp zone, in a cross-sectional area of the contact pin, spanning across the X-direction and the Y-direction, the crimp zone comprising:
• a central crosspiece area having two opposite crosspiece edges which are substantially parallel to the X-direction,
• two wing areas adjacent to the crosspiece area in a positive X-direction and a negative X-direction, wherein each of the two wing areas comprises two ear areas,
• wherein one of the two ear areas of each of the two wing areas projects beyond the crosspiece area in a positive Y-direction, and another of the two ear areas of each of the two wing areas projects beyond the crosspiece area in a negative Y-direction,
• wherein the crosspiece area is limited by a crosspiece rectangle,
• wherein the two ear areas are limited by ear rectangles,
• wherein inner corner points of the ear rectangles facing a center of gravity of the cross-sectional area coincide with corner points of the crosspiece rectangle, wherein the crosspiece rectangle, in the X-direction, has a crosspiece width between 9% and 29% of a starting material thickness of the contact pin, and, in the Y-direction, has a crosspiece thickness of between 35% and 55% of the starting material thickness,
• wherein the ear rectangles, in the X-direction, have an ear width of between 40% and 60% of the starting material thickness, and in the Y-direction, have an ear thickness of between 15% and 35% of the starting material thickness.
