FIG. 4 is a graph of force versus deflection curve 144 for latch mechanism 116 of FIG. 2A and force versus deflection curve 146 for alternative latch mechanism 216 of FIG. 5A. In the illustrated embodiment, the force from latch mechanism 116 is nominally about 96 Newtons (N). This can occur when all the components are nominally sized and positioned, which results in a nominal deflection of 0.8 mm. However, there can be deviations from the nominal configuration, for example, due to tolerance stacking. This can cause, for example, pawl 132 to engage lug 106 (both shown in FIG. 2A) sooner or later. In an example of the former case, latch mechanism 116 can be under increased stress due to the deflection being 1.4 mm, which results in a force of about 144 N. In an example of the latter case, latch mechanism 116 can be under decreased stress due to the deflection being 0.2 mm, which results in a force of about 53 N. In either situation, latch mechanism 116 provides sufficient force to maintain contact between input connector 108 and output connector 114 without overly stressing CSCB 100 or PCI cassette 102 (all shown in FIG. 1A).
