  • Image-related device with printed-circuit assembly cantilevered from sheet-metal base & with clip fastenings
    Patent number: 5863141
    Abstract: In a mounting system for an assembly in a high-frequency desktop device, a chassis element ("element") provides ground. For best ground, features formed in the element near a first edge of the assembly force the two together with no fastener there. Fasteners or other provisions secure the assembly, near its second edge, to the element. The features capture the first edge at installation; the fasteners etc. secure the assembly, near its second edge so that the features pinch the first. In another form of the system (1) first raised shapes formed in the element support the assembly near its first edge; (2) features, also formed in the element next to the first shapes, engage and capture the first edge; (3) second raised shapes, formed in the element, support the assembly near its second edge; and (4) fasteners etc. secure the assembly, near its second edge.
