Patent number: 7542279Abstract: A mounting apparatus is provided for a data storage device defining a mounting hole. The mounting apparatus includes a bracket for accommodating the data storage device and a locking latch. The bracket includes a side plate forming a cantilever thereon. A receiving portion is formed at a free end of the cantilever. The locking latch is pivotally attached to the side plate. The locking latch has an initial position parallel to the side plate. A projecting portion extends from the locking member, and is received by the receiving portion of the cantilever. A securing member is formed on the locking latch. When the locking latch is pivoted away from the side plate, the cantilever is distorted to store a potential elastic energy for urging the locking latch to move back to the initial position, thereby the securing member engaging into the mounting hole of the data storage device.Type: GrantFiled: May 11, 2006Date of Patent: June 2, 2009Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Yun-Lung Chen, Quan-Guang Du, Dong Qin
