A tool-actuated ejector for extracting electronic modular components. The ejector, which functions as a levered cam, has a body with a first end, a second end and a pivot located intermediate the first and second ends. A tool-receiving socket mounts at the second end. A tool, such as a screwdriver with a blade that matches the shape of the socket, actuates the ejector by applying a force to the socket. A cam, located at the first end, engages the electronic modular component. To provide a mechanical advantage, the distance between the tool-receiving socket and the pivot, which constitutes one lever arm, is greater than the distance between the cam and the pivot, which constitutes a second lever arm. In addition, a shock absorber mounts on the body and gliders extend below the body to provide stability and balance to the ejector. The ejector mounts in a casing having a tool passage that communicates with the tool-receiving socket and the exterior of the casing.

Tool-actuated ejector mechanism for extracting electronic modular components

An electromagnetic interference shielding gasket extends through a slot in a face plate assembly bracket arm from the underside thereof. The gasket is secured to the underside of the bracket arm to avoid the problem of the gasket peeling from the bracket arm when circuit card assemblies are inserted into and removed from slots in a shelf unit.
