1. Field of the Invention
The present invention relates to a computer power supply, and particularly to a computer power supply mounting apparatus.
2. Description of the Related Art
Many types of electronic devices, such as computers, include a power supply which is mounted in a housing or chassis along with the other circuits, components, and peripheral devices. Since the power supply receives alternating current electrical power and converts the alternating current to direct current for operating the various electrical components, safety regulations require that the power supply be completely enclosed in a case to prevent access to potentially harmful high voltages. In the past, most power supplies were mounted to the chassis using several screws, making it difficult and time consuming to replace or remove the power supply for repair.
In U.S. Pat. No. 5,790,372, an improved power supply mounting apparatus is disclosed. A computer includes a chassis and a power supply mounted in the chassis. One or more hooks are provided on the chassis and the power supply, so that the power supply can be placed in the chassis and moved relative to the chassis to engage the hooks and secure the power supply in the chassis against movement in a first plane. A screw is provided for engaging the chassis and the power supply for securing the power supply against movement in a plane perpendicular to the first plane. A tab on a wall of the chassis guides the power supply.
In U.S. Pat. No. 6,270,046, another improved power supply mounting apparatus is disclosed. A computer system includes a chassis which is formed by assembling front, rear and bottom panels together. An apparatus for mounting a switching power supply to the computer system includes a bracket and a drive cage with a pair of hooks. The drive cage bridges between the front and rear panels. The bracket includes a hinge portion and a supporting portion adapted to support the switching power supply. The hinge portion of the bracket is slidably engaged with the hooks for fixing the switching power supply to the rear panel of the chassis with screws.
Therefore, what is needed is an screwless apparatus for mounting a power supply, thereby to enable easy and convenient installation and removal of the power supply.
