Abstract
An expanding card mechanism for protecting a circuit board is disclosed. The expanding card mechanism includes an upper case, a lower case, a plastic frame rack, a plastic baffle and an interface joint. The main feature is that two sides of the plastic frame rack form two positioning guiding tracks, respectively, for matching an inside concave slot guiding tracks of the two sides on the lower case and the plastic frame rack is slid well in the lower case until positioning convex blocks of the plastic frame are locked in positioning pinholes of the lower case. Furthermore, the two positioning convex blocks of the plastic baffle matching the two corresponding positioning guiding slots of the plastic frame rack are fixed well to form foolproof protection, and the circuit board and the interface joint are equipped with the lower case.
