Claim of US Patent No. 10,973,157

1. A cassette for insertion and removal of an edge-connected printed circuit card connectable to a server chassis, comprising:a housing comprising a bottom wall having an elongated slot and a catch formed thereon;
a connector sub-assembly overlying the bottom wall and comprising a base having a first end, a central section, and a second end, wherein the connector sub-assembly includes a first fastener hole formed in the connector sub-assembly and configured to receive a fastener, and the second end of the connector sub-assembly includes a second fastener hole;
a guide sub-assembly underlying the bottom wall having a spring latch formed thereon, the spring latch operable in a first state to engage the catch to prevent movement of the connector sub-assembly and the guide sub-assembly relative to the housing; and
a spacer sub-assembly underlying the connector sub-assembly and overlying the bottom wall of the housing, the spacer sub-assembly having a third fastener hole and a locating pin extending therefrom, wherein the third fastener hole is configured to receive the fastener, wherein the locating pin is configured to align the connector sub-assembly with the spacer sub-assembly, and wherein the spring latch is operable in a second state to clear the catch to permit the connector sub-assembly and the guide sub-assembly to slide in unison in the elongated slot.
