Abstract

An electrical connector comprises a body accommodating one group of staggered rows of spring contacts for engagement with cone-shaped contacts arranged in correspondingly staggered rows on a printed circuit board. The spring contacts of one row have intermediate flattened parts which slidingly engage with peaks of the corresponding dome-shaped contacts thereby requiring low insertion force while curved parts of spring contacts of the other row are riding up the convex profile of the corresponding dome-shaped contacts requiring high insertion force. Two similar groups of staggered rows of spring contacts may be provided for accommodating boards having staggered rows of raised contacts on both sides of the board.
