Abstract:
A circuit board ejector mechanism operable to provide resiliently biased engagement between a first part of an electrical connector mounted on a circuit board and a mutually engaging second part of said electrical connector mounted on a back plane, said first and second parts of said electrical connector providing electrical connection between said circuit board and said back plane, said ejector mechanism comprising:an engaging projection mountable on a chassis with respect to which said back plane is mounted; and a lever arm pivotally mountable about an axis that passes through said circuit board and configured to engage said engaging projection, said lever arm being operable to apply an engaging force to said engaging projection to urge said circuit board towards said back plane when moved from a first position to a second position, which engaging force causes said first and second parts of the connector to engage, wherein said engagement of said lever arm and said engaging projection is provided by a flexible coupling which allows relative movement of said circuit board with respect to said back plane, and wherein the flexible coupling provides a biasing force which biases said circuit board towards said back plane.
