A cover latch mechanism, used for fixing a first cover to a second cover, includes a latching groove defined in the second cover; a latching hook extending from a surface of the first cover corresponding to the latching groove, the latching hook engaged with the latching groove; and a connecting member fixed to the second cover. The connecting member includes a latching portion according to the latching hook. The latching portion defines a receiving depression to receive the latching hook, and an elastic resisting protrusion extending from the latching portion adjacent to the receiving depression to resist the latching hook in the latching groove.
