US Patent 7212400 Fixing apparatus for motherboard

A fixing apparatus is for fixing a motherboard (60) in a chassis (20). The chassis includes a supporting board (30). The supporting plate includes a number of clips (36, 38), and a screw hole (391). The motherboard (60) defines a number of through holes (62) corresponding to a number of standoff (40) disposed on the supporting plate, a number of apertures (64), and a fixing hole (66). The through holes each include a circular hole (622), and a slot (624). The standoffs each comprise a head (42), a neck (44), and a base (46). The clips each include a shoulder (367, 387), and a catch (366, 386). The standoffs and the clips engage the through hole and the apertures of the supporting plate to attach the motherboard in the chassis. A stud extends through the fixing hole and engages the screw hole to secure the motherboard in the chassis.
