Abstract
Abstract The eject-lever apparatus of the present invention is arranged in an optical transceiver having a substrate, where the optical transceiver is being received in a housing having a slot arranged therein with the substrate being plugged into the slot, the apparatus comprising: at least a lever having a cam arranged therein, being disposed at the receiving end of the optic fiber of the optical transceiver; and at least a linkage rod, being deposed on a side of the optical transceiver, wherein the lever is actuated to rotate about an axis from a first location thereof to a second position thereof by exerting a force thereon while driving the cam to rotate accordingly for transmitting the force to an end of the linkage rod enabling the linkage rod to exert a force on the housing so as to generate a reacting force acting on the lever and thus cause the optical transceiver to move out to compress an elastic body and be ejected from the slot gradually; finally, the substrate is totally released from the slot for freeing the optical transceiver from the housing while the lever is in the second position, and thereafter, a resilience force generated by the compressed elastic body enables the returning of the lever from the second position to the first position while the lever is lightly moved.
