Abstract
Abstract A snap-together enclosure comprises a cover, a shutter mechanism, and a base plate. The enclosure is designed to encase a jack receptacle body which is heat staked to a terminal block. The shutter mechanism is snapped into a hole in the cover and is held in place by means of tabs on the shutter and interfering ridges on the cover. The terminal block is snapped into the base plate by means of tabs on the base plate and interfering ridges on the terminal block. Finally, the cover is snapped onto the base plate, again by use of tabs and interfering ridges on the cover and base plate respectively. When the cover and shutter assembly is attached to the base plate, the jack receptacle body, enclosed therein, pushes against back walls of the tabs on the shutter to prevent the shutter from disengaging with the ridges on the cover. The cover further holds the terminal block in position by integral ribs within the cover pressing against back walls of tabs on the base plate, thereby preventing the terminal block from disengaging from the base plate.
