Ejector for printed circuit board plug-in unit

A printed circuit board plug-in unit for a card cage having a pair of printed circuit board card guides arranged with an electrical connector spaced adjacent the end of the card guides and between the card guides to receive the plug-in unit at said electrical connector, comprising a printed circuit board plug-in unit comprising a printed circuit board;

• a panel member secured to one end of the printed circuit board in a plane substantially perpendicular thereto;
• and an electrical connector secured to said board adjacent the opposite end of the printed circuit board from said panel member, said electrical connector being adapted to be electrically interconnected to the electrical connector for the card cage when the plug-in unit is mounted between the card guides;
• a common ejecting surface for the card cage functioning as a fixed ejection surface for extracting the electrical connector secured to the printed circuit board from the electrical connector for the card cage, said ejecting surface being arranged immediately adjacent the panel member when the two electrical connectors are interconnected and on the same side of the panel member as the printed circuit board, said panel member having an aperture adjacent at least one end of the panel member for exposing said ejecting surface therethrough;
• bracket means secured to said panel member adjacent the aperture for the panel member;
• printed circuit card ejecting means, said ejecting means being constructed and defined to extend through the aperture for the panel for engaging said ejecting surface while being accessible for pivotal movement on the opposite side of the panel member, said ejecting means and said bracket means being defined relative to one another for permitting the pivotal movement of said ejecting means relative to said bracket means to cause the ejecting means to engage the ejecting surf.ace in response to a pivoting force being applied to the ejecting means for extracting the electrical connectors from one another in response to the pivotal movement of the ejecting means, and means for securing said bracket means and said ejecting means to said printed circuit board while permitting said pivotal movement of said ejecting means.
