ABSTRACT:
A front panel for mounting a printed circuit board in a card cage. A central frame is formed with an integral extrusion from which integral printed circuit board mounting brackets can be formed on one surface of the central frame. Ejector assemblies mount at each end of the central frame and include an extruded mounting bracket that attaches to the central frame, an extruded ejection handle with legs that straddle the mounting frame and a solid handle portion with a pivot that mounts to a solid pin captured in the assembled structure. Rotating the extraction handle causes the legs to bear against the card cage and fully extract the printed circuit board from a back plane. When adjacent printed circuit boards are fully seated, the extraction handles align parallel the central plane and can support identifying labels in a clear and secure fashion.
