  • Patent number: 4999744
    Abstract: This ejector mechanism supplies a force to remove an assembly of printed circuit boards (PCB's) from an enclosure. Each PCB in the assembly is electrically connected by a projecting rear portion of the PCB which engages a multiple contact connector attached to the enclosure. The friction associated with such engagement resists sliding the PCB assembly to disengage the connector. In an embodiment, a U-shaped lever is pivotally mounted to the assembly and applies a distributed force through each leg which is substantially adjacent each PCB. This provides force application substantially in the place of each PCB, thereby maximizing the desired force and minimizing undesired torque on each PCB.
