Board-to-board connector including an insulative spacer having a conducting surface and U-shaped contacts

Apparatus for electrically connecting a plurality of printed circuit boards, comprising:

• (a) a connecting member adapted for disposal between a first of said printed circuit boards and a second of said printed circuit boards, said connecting member comprising an insulating spacer having mounting apertures therein for mounting said connecting member between said first and second printed circuit boards;
• (b) electrical signal transmission means on said connecting member for providing electrical connection between said first printed circuit board and said second printed circuit board, said electrical signal transmission means comprising a U-shaped contact extending through the connecting member such that a first sidewall of the U-shaped contact is adapted to physically contact a desired terminal of the first board and a second sidewall of the U-shaped contact is adapted to physically contact a desired terminal of the second board;
• and
• (c) a conducting surface on said connecting member, said conducting surface being in contact with said electrical signal transmission means for electrically connecting said electrical signal transmission means with a third printed circuit board.
