Abstract: A method and apparatus for mounting a motherboard to a chassis of a personal computer using only a single screw. A number of standoffs snap into the base of the chassis, electrically contacting the chassis. Each standoff includes a projection. The motherboard includes apertures for accepting the projections such that when an ramp and shelf of each projection is aligned with the motherboard, the motherboard is positioned a fixed distance from the chassis. A mounting bracket also includes a number of projections. Apertures provided in the motherboard correspond to the projections of the mounting bracket. The surface of each side of the motherboard surrounding each aperture is plated with an electrically conductive material to form a conductive path between the motherboard and the standoffs and the bracket. The projections of the bracket are inserted into the corresponding apertures in the motherboard. A screw is inserted through a wall of the chassis and into a threaded hole in the bracket. As the screw is tightened, the bracket is drawn toward the wall of the chassis. This firmly engages the motherboard to the stand-offs and to the bracket, firmly maintaining the motherboard in a fixed position relative to the chassis and forming a solid electrical ground connection between the motherboard and the chassis. Also, as the screw is tightened, input and output connectors, which are coupled to the motherboard, are drawn toward the wall of the chassis making firm contact with a plate or gasket.

Abstract translation: 一种用于仅使用单个螺钉将母板安装到个人计算机的底盘的方法和装置。 一些支架卡入机箱的底座，与机箱电气接触。 每个支架都包括一个投影。 主板包括用于接收突起的孔，使得当每个突起的斜面和搁架与主板对准时，母板与底盘定位一段距离。 安装支架还包括多个突起。 主板上设置的孔对应于安装支架的突起。 围绕每个孔的母板的每一面的表面镀有导电材料，以在母板与支座和支架之间形成导电路径。 支架的突起插入主板上相应的孔中。 螺钉通过底盘的壁插入支架的螺纹孔中。 当螺丝拧紧时，支架被拉向底盘的墙壁。 这将主板牢固地接合到支架和支架上，将主板牢固地保持在相对于底盘的固定位置，并在主板和底盘之间形成牢固的电接地连接。 而且，当拧紧螺钉时，连接到母板上的输入和输出连接器被拉向底盘的壁，从而与板或垫圈牢固接触。
