ABSTRACT:
An electrical contact of the type having a square post contact section at one end and a box-like receptacle contact section at the other end matable with such a post section of a like contact, for use in stackable connectors for interconnecting printed circuit boards of a parallel array, is formed to have a square post with flat side surfaces with an originally square cross-section of dimensions matable with the box-like receptacle contact section, but the contact is modified by having the corners of the square post section smoothly rounded. The diagonal of the cross-section is thereby substantially reduced and is insertable through a through-hole of the board which has a diameter similarly substantially smaller than the diagonal of the original square cross-section, while the post section maintains side surfaces which remain substantially flat for mating with an unmodified box-like receptacle contact section. The contact maintains at least the mating characteristics of a contact having the original square cross-section post section, while a smaller array of through-holes for board interconnection is possible because the hole diameters are reduced.
