Background technique

For now, computer equipment is a very popular electronic device. For computer equipment seen on the market, such as desktop computers, notebook computers, or servers, the peripheral hardware devices used in the computer, such as adapter cards ( Peripheral Component Interconnect Card, PCI card) and other external hardware devices must be electrically connected to the circuit board so that the circuit board and the computer's peripheral hardware system can communicate with each other and transmit signals before performing the preset functions of the peripheral hardware.

The traditional way of fixing the adapter card of the server is to lock a fixed bracket on the server shell, so that the adapter card can be installed therein and electrically connected with the slot on the circuit board. One end of the adapter card is provided with a bent fixing piece, and a screw hole is opened on the fixing piece, and a screw is passed through the screw hole to be locked on the fixing bracket, so that the adapter card is fixed inside the computer device. However, during the process of installing or removing the adapter card, an assistant tool must be used to lock or loosen the screws, and it takes too long to lock or remove the screws. The process is too complicated and time-consuming, which is inconvenient. At the same time, during the process of loosening the screws, the screws are easy to drop on the main board, causing the circuit of the main board to be short-circuited and burned.

In order to solve the problem that an assistant tool must be used to screw the screws during the assembly and disassembly of the adapter card, a fixing mechanism for the fitting seat is disclosed in Taiwan Patent No. 562164, which includes a fitting seat and a fixing strip. The fitting seat is arranged on the casing of the computer device, and one end of the fixing bar is pivotally arranged at a position adjacent to the fitting seat of the casing, so that the other end of the fixing strip can be pivoted away from or close to the fitting seat for abutment. The object to be fixed on the fitting seat is clamped and fixed.

In addition, US Pat. No. 7,161,798 discloses an expansion card fixing device, which includes a first fixing frame, a second fixing frame, and a rear plate. Several expansion card slots are arranged on the rear board, and the first fixing frame is fixed on the rear board in a rotatable relationship. The second fixing frame is fixed on the first fixing frame, and the second fixing frame is provided with a plurality of abutting parts for fixing the expansion card in the expansion card slot.

Although the above two patents solve the problems caused by the adapter card being fixed by screw locking, both patents use a single pressing component (such as the fixing bar of the No. 562164 case, and the second fixing frame of the No. 7,161,798 case) Holding the adapter card, if the computer device is shaken or impacted by an external force, the pressing component will easily loosen from the adapter card and lose its pressing function.
