Positive locking mechanism

摘要

A positive locking mechanism is provided for securing a plug-in electronic module in a chassis. A threaded element is provided for attaching the electronic module to the chassis and tightening of the threaded element forces a module connector into engagement with a mating connector in the chassis. A pivotal driver blade is provided for turning the threaded element and, after the connectors are mated, the driver blade is pivoted and a cam thereon actuates wedges which provide a good thermal interface between the electronic module and the chassis. The driver blade also serves as means for extracting the plug-in electronic module from the chassis.
