Abstract
The eject mechanism is composed of a two-arm lever actuatable with a ram, so that an actuation of the ram acting on the first lever arm creates a release of the plug in contact and an eject motion of the plug in assembly with the assistance of the second lever spatially allocated to the plug-side end of the plug in assembly. In order to achieve different transmission ratios, the first lever arm and the end of the ram facing toward it are fashioned and spatially allocated to one another so that the ram applies to a long lever arm in a first lever phase and applies to a short lever arm in a second lever phase.
Claims7
An ejection mechanism for ejecting a plug-in assembly which is insertable into slot-like opening of a housing, said mechanism having a lever arm actuatable by a ram, said lever arm being mounted at a pivot axis to have a first lever arm portion and a second lever arm portion with the ram contacting the first lever arm portion as the end of the second lever arm portion engages the plug-in assembly to eject it from said opening, the improvement comprising the ram facing toward the first lever arm portion having a transverse component extending from the free end of the ram up to approximately the pivot point of the lever arm so that the ram is applied to the end of the first lever arm portion during a first lever action and is applied to a shorter portion of the lever arm during a second lever phase to change the lever ratio for the two lever arm portions.
