Electrical connector between a pair of printed circuit boards

An electrical connector for making an electrical connection between a pair of printed circuit boards with one board located edgewise to the other board, said electrical connector comprising:

• a vertical pin header having a plurality of through holes formed in said header, electrical positive first contacts each mounted within each of said through holes, first alignment means mounted on said vertical pin header, said first contacts adapted to establish an electrical connection with one of the printed circuit boards;
• a right angle receptacle having a plurality of through openings, electrical positive second contacts each mounted within each of said through openings, wherein each of said second contacts being elongated and in a shape of a right angle, second alignment means mounted on said right angle receptacle, said first alignment means being received in said second alignment means and said first contacts electrically connecting with said second contacts when said vertical pin header is matingly connected with said right angle receptacle, said second contacts adapted to establish an electrical connection with the other of the printed circuit boards;
• and
• said vertical pin header including a first housing constructed of an insulative material, said vertical pin header having a first exterior wall surface, a first electrically conductive grounding layer covering substantially the entire said first exterior wall surface, a plurality of first contact points integrally formed from said first electrically conductive grounding layer, wherein each of said first contact points comprising a small protrusion, said first contact points surrounding each of said electrical positive first contacts for facilitating electrical grounding connection with a respective printed circuit board.
