Abstract
Abstract An ejector for a printed circuit board plug-in unit for use with printed circuit board cages having a fixed ejection surface. The ejector is constructed and defined to be pivotally mounted through an aperture provided for the panel member of the plug-in unit for pivotally engaging the fixed ejection surface of the cage system for extracting the electrical connector carried by the printed circuit board of the plug-in unit from the electrical connector of the cage system. The ejector has a handle portion with an extraction portion extending through the aperture of the panel along with a portion defining a bearing surface for engaging the fixed ejection surface. A bracket secured to the panel member also pivotally secures the ejector extraction portion to the printed circuit board.
