ABSTRACT:
Insertion and ejection mechanisms for modular boards and cards. Mechanisms are provided for coupling the motion of insertion/ejection handles coupled to a modular board or a board carrier frame to which a board is attached. The mechanisms include a single-bar linkage, a rack and pinion-based configuration, a two-bar linkage, and a telescoping configuration. Applying an input force to one of the handles causes the board to be urged inward in a chassis slot, thus coupling the connectors on the board with mating connectors on a backplane mounted within the chassis. The input force is coupled via the various handle-coupling mechanisms to the other handle, producing a result similar to if a force was applied to both handles at the same time. In a similar manner, a board may be ejected by applying a force to a single handle to cause that handle to rotate outward. An automated retention screw insertion and extraction mechanism is also disclosed.
