Described is a method of latching a covered electronic logic card or "book", into a logic cage such that contact pin insert/extract forces are overcome with a user friendly "feel", positive retention is achieved, and system tolerances are corrected for (allowing full seating of the connectors between the logic book and cage). (Image Omitted) An overview of the logic card/cage concept is shown in Fig. 1. The books 1 are equipped with latches 2 at the top and bottom and are inserted into a logic cage 10 which includes a backplane card 3 at its rear and latch engagement features 4 at its top and bottom. Also included on cage 10 are secondary latch bars 5. Connection is made between books 1 and the backplane inside the cage (not shown). (Image Omitted) Fig. 2 shows details of an individual latch.
