Abstract: A one piece card guide for edge grounding a printed circuit board and guiding the board to a mounted position. The card guide is formed out of a single piece comprising an integrally formed pair of sidewalls facing each other and spaced apart to form a longitudinal slot into which the circuit board is inserted. At least one pair of grounding points is integrally formed into the side walls for contact with an inserted circuit board. The grounding points may be formed as integral spring fingers on opposite sides of the sidewalls to maximize the contact with the circuit board. The card guide allows for different numbers of grounding points in the card guide. The single piece construction of the card guide reduces intermittent contact with circuit cards by providing a guide that ensures continuous edge grounding.
