This article describes a means of grounding the housing of a personal computer (PC) by contact engagement between formed spring tabs on the cover and guide rails on the base of the frame. In order to maximize the electrical shielding capability of the PC enclosure assembly, i.e., to reduce the possibility that electromag (Image Omitted) netic radiation from the machine will interfere with communication signals, such as television transmissions, it is desirable to electrically ground the cover to the machine frame in a number of places. In particular, it is desirable to ground the cover to the frame at various places along each seam between them and to minimize the gaps among such grounding points. This disclosure describes means to achieve this kind of grounding without significantly affecting the method of assembly; i.e.
