A card cage ejector combination is provided including a card cage or housing for receiving printed circuit boards. The housing has an opening for insertion of the PCBs. The ejector mechanism is formed preferably with a single sheet metal piece including a lever/handle portion, a pivot portion, a PCB engagement element and a transmission portion extending from the pivot portion to the PCB engagement portion. The card cage includes a pivot support which is formed by protruding a portion of the sheet metal of the card cage. The pivot portion of the ejector then cooperates with the protruding pivot support and the ejector level can pivot about the pivot support. A fixing portion is also formed from the sheet metal of the card cage. An opening is provided in the card cage adjacent to the pivot support and adjacent to the fixing portion. The PCB engagement portion of the ejector lever is inserted into the opening and the pivot portion is mounted on the pivot support. The ejector may be moved from a first non-fixed position, wherein the PCB board is not fixed, to a fixed position wherein the PCB board is fixed. In the fixed position, the fixing portion of the cage frictionally engages the ejector lever for maintaining it in position mounted on the pivot support. The ejector lever and card cage hold the PCB in a fixed position without the use of retaining fasteners for retaining the ejector relative to the card cage.
