Patent ID: 7352590

Claim:
An eject-lever apparatus arranged in an optical transceiver having a substrate, where the optical transceiver is received in a housing having a slot arranged therein while the substrate is plugged in the slot, the eject-lever apparatus comprising: at least a lever having a cam arranged therein, being disposed at the receiving end of an optic fiber of the optical transceiver; and at least a linkage mechanism, being deposed on a side of the optical transceiver while having at least an end thereof abutted against the housing; wherein the lever is actuated to rotate about an axis by exerting a force thereon and enabling the cam arranged at a side of the axis to rotate accordingly for transmitting the force to the linkage mechanism, and when the lever is rotated, the linkage mechanism driving the optical transceiver to move and disengage from the slot and the housing, wherein the lever is actuated to rotate about an axis by exerting a force thereon while driving the cam to rotate accordingly for transmitting the force to the linkage mechanism enabling the end of the linkage mechanism abutted against the housing to exert a force on the housing so as to generate a reacting force acting on the optical transceiver to enable the substrate of the optical transceiver to disengage from the slot and eventually release the optical transceiver from the housing.
