Abstract

Figs. 1 and 2 illustrate a screw-less fastening arrangement for mounting parts on housings of electronic systems, particularly computer systems and the like. The part to be attached is housed in and held by a plastic cartridge or capsule 1 containing a molded split-tenon construction 2 which features an integral spring arrangement 2a and a lip 2b. The housing 3, to which this construction attaches, contains a tapered opening 4 into which the tenon 2 is inserted. As shown in Fig. 2, as the tenon enters the opening 4, it collapses and then expands as the radiused lip exits through the opposite side, thereby holding the part to the housing wall. The plastic springs 2a keep a constant tension between the attached part and the housing wall to compensate for any dimensional differences or changes due to part tolerances.
