Abstract
Abstract An ejection and grounding system for rack-mounted plug-in modules includes an angle lever which bears against a frame element to extract a module mounted in a rack. The frame element contains an electrical buss means for grounding the modules. A bracket is attached to the module and grounds the module to the buss; the bracket also supports the angle lever so that it rotates parallel to the module.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
128 words
An ejection and grounding system for rack-mounted plug in modules comprising: a fixed and elongated frame element having an elongated recess that is open in front; a groundable electrical buss means located in the recess; an electrically conductive bracket adapted for physical and electrical connection to a rack-mounted plug-in module, the bracket having an electrically conductive prong for electrical contact with the buss means; an angle lever pivotally secured to the bracket and rotatable parallel to the module, the lever being urged against the frame element to extract the module; and means for locking the angle lever in a position, said locking means comprising a leaf spring attached to the angle lever, the leaf spring being detachably securable to a component which is fixed to the plug-in module.
