• a connector shroud;
• and
• a press-fit pin penetrating the connector shroud,
• the press-fit pin having a head, a contact section, a flange section, a shroud engaging section, a first axially elongated press-fit section and a second axially elongated press-fit section, the first and second press-fit sections being insertable through a through-hole in a connector shroud bottom wall and the shroud engaging section being insertable into the through-hole and fixedly engaging the connector shroud bottom wall with the contact section projecting into the interior of the connector shroud, the first press-fit section and the second press-fit section projecting beyond the bottom wall of the connector shroud;
• and
• the first press-fit section and the second press-fit section having respective central portions of respective maximum diameters, respective centers of the first and second central portions being separated by a first axial distance different from a second axial distance between respective centers of the first and second through-holes such that, as the press-fit pin is pressed for axial movement relatively to, and successive insertion of the first and second press-fit sections into, the first and second through-holes, the respective central portions of the first and second press-fit sections are inserted into the first and second through-holes, respectively, at different, successive times.

A press-fit pin insertable through aligned, first and second through-holes of first and second parallel boards spaced apart by a first distance, the press-fit pin comprising:

• a head, a first axially elongated press-fit section, a central section, a second press-fit section and a pin integrally formed and disposed in axial alignment;
• the first and second press-fit sections each having an axially extending depression therein bounded by a pair of longitudinal ribs spaced by respective, fixed maximum dimensions, transverse to the axis, along respective central sections thereof and the ribs tapering inwardly from opposite ends of the central portion of the depression to opposite ends of the depression, the fixed, maximum dimension of the depression of the first press-fit section being greater than the fixed, maximum dimension of the depression of the second press-fit section and respectively being selected, relatively to respective first and second diameters of the first and second through-holes, to provide secure engagement thereof when the central portions of the first and second press-fit section are respectively inserted fully into the respective first and second through-holes;
• and
• the first press-fit section and the second press-fit section having respective central portions of respective maximum diameters, respective centers of the first and second central portions being separated by a first axial distance different from a second axial distance between respective centers of the first and second through-holes such that, as the press-fit pin is pressed for axial movement relatively to, and successive insertion of the first and second press-fit sections into, the first and second through-holes, the respective central portions of the first and second press-fit sections are inserted into the first and second through-holes, respectively, at different, successive times.
