ABSTRACT:
A fastening assembly for mounting a main circuit card a fixedly spaced distance from a mounting wall, and for aligning a subsidiary connector of a subsidiary circuit card to a main connector mounted on a top surface of the main circuit card is provided. The fastening assemby comprises a pin and a support button. The pin has a bottom portion that passes through mounting apertures within a main connector mounted to a top surface of a main circuit card that extend from the center axis at most a first distance, and wherein the bottom portion extends from the center axis at least a second distance. The pin also has a shaft portion fixedly spaced above and co-axial with the bottom portion that has at least a narrow section of the shaft portion that extends from the center axis a distance less then the second distance such that a lip is formed by a side of the bottom portion where the bottom portion meets the shaft portion at the narrow section, and wherein at least a wide section of the shaft portion of the pin extends from the center axis at least the second distance. The pin also has an upper end with cross sectional area greater than the cross sectional area of the shaft portion and sized to pass through the mounting apertures. The upper end has a flange extending out from the center axis a distance greater than the first distance such that the flange encounters the main connector when the pin is inserted in the mounting apertures.
