HELICAL-DRIVE CAPTIVE PANEL FASTENER FOR INSERTING, EXTRACTING, AND FLUSH-MOUNTING PANELS IN MUTUAL CONTACTING ENGAGEMENT

摘要

A fastener assembly for bringing into contacting engagement a module-mounting plate with a retaining-sleeve aperture and a module-supporting plate with a receptacle aperture includes first and second sub-assemblies. The first sub-assembly includes a shaft-retaining sleeve within which there is retained for rotation relative to the shaft-retaining sleeve a drive shaft having drive-shaft distal and proximate portions, the distal portion having defined thereabout a helical grove. The shaft-retaining sleeve is press fit within the retaining-sleeve aperture such that the drive-shaft proximal and distal portions protrude from opposite sides of the module-mounting plate. Press fit into the receptacle aperture is a shaft receptacle defining a through-bore into which protrudes a drive pin configured for selective mechanical registration with the helical groove such that rotation of the drive shaft in a first direction draws the plates into flush contacting engagement, while rotation in a second direction opposite the first direction separates the plates.
