  • Patent number: 7990736
    Abstract: A mounting apparatus is configured for securing an expansion card with a support portion, and includes a chassis with a plate, and a securing member pivotably secured on the plate. The plate defines an opening for the support portion of the expansion card inserting therethrough. A positioning portion is formed on the plate to locate the support portion of the expansion card. The positioning portion defines a locking hole therein. The securing member includes a bent portion and a locking portion to sandwich the support portion of the expansion card and the positioning portion of the plate therebetween. A locking block protrudes from the locking portion to engage in the locking hole of the positioning portion. The locking portion is resiliently deformable to disengage the locking block from the locking hole of the positioning portion.

  • Patent number: 7744172
    Abstract: A computer enclosure includes a rear plate defining a through opening therein, a mounting bracket secured on the rear plate to cover the through opening of the rear plate, and an interchangeable I/O plate. The mounting bracket includes a top wall perpendicular to the rear plate and, a front wall parallel to the rear plate. The top wall forms an engaging tab thereon. The front wall defines a through opening therein corresponding to the through opening of the rear plate. The I/O plate is configured for covering the through opening of the front wall of the mounting bracket, and defines a securing hole therein for receiving the engaging tab of the mounting bracket. A locking piece is formed on the I/O plate and together with the I/O plate sandwiches an edge of the through opening of the mounting bracket therebetween.

  • Patent number: 7447016
    Abstract: A disk drive cage includes a bracket (20) and a shielding member (10). The bracket includes two parallel side plates (21, 22). A positioning flange (212) is bent from one of the side plates (21). The shielding member includes a front wall (13), a top wall (15), a bottom wall (16), a first side wall (12), and a second side wall (14). A resilient lip piece (141) is formed on the second side wall and having at least one locking tab (142) engaging with the positioning flange when the shielding member inserts into the bracket. The top wall and the bottom wall has arc-shaped edges (152, 162) to allow resilient deformation of the first side wall towards the arc-shaped edges by the other one of the side plates (22), and the shielding member rotating out from the bracket.
