Description

Expansion-card assemblies and expansion-card cages

The invention relates to an expansion card assembly and an expansion card rack, in particular to an expansion card assembly and an expansion card rack with a fixed pressure plate.

With the development and progress of electronic technology, the current development trend of electronic devices is moving towards the direction of powerful computing functions, high speed and small size. In other words, in order for electronic devices to be competitive, in addition to fast speed and high performance It has the advantages of thinness, miniaturization, and continuous expansion.

With the reduction of the volume of the electronic device, the internal space of the electronic device is also limited. Therefore, when the internal access device or expansion interface card is to be installed or replaced, the internal space for operation is even more limited. In traditional electronic devices, a fixed bracket is usually used to connect and lock a fixed access device or a high-speed peripheral device internal connection bus (PCIe card), and then the fixed bracket is connected to the housing of the electronic device and locked. so that the access device or the PCIe card can be securely installed inside the electronic device. In the traditional method, screws are directly used for connection and locking.

However, in the process of screw locking, the screws need to be aligned with the screw holes one by one and then locked in, which requires a lot of man-hours, and the screw locking is performed in a narrow space. If the screw is accidentally dropped, picking up the dropped screw will make the work more difficult, not to mention if the screw falls off during the locking process and is lost, or even the size of the screw and the screw hole do not match, Or the corresponding screw holes are damaged due to excessive force during the locking process, etc., which will cause the subsequent failure to successfully perform the setting and replacement of the access device or PCIe card.

The present invention provides an expansion card assembly and an expansion card holder, so as to reduce the usage amount of screws and the locking time when fixing the expansion card.

The expansion card holder disclosed in an embodiment of the present invention is used for installing at least one expansion card. The expansion card holder includes a frame body, a fixed pressing plate and a locking piece. The frame body includes a back plate, a first assembly plate and a second assembly plate. The back plate has two opposite sides and at least two through grooves penetrating through the opposite two sides. The first assembling board and the second assembling board respectively protrude from two opposite sides of the backboard. The first assembly board is used for installing a riser card in which at least one expansion card is inserted, and at least two through grooves on the back plate are used for exposing the at least one expansion card. The second assembly board has a coupling hole. The fixed pressing plate has a perforation. The locking piece passes through the through hole of the fixed pressing plate and is locked to the combination hole, so that the fixed pressing plate is used to press against a baffle of at least one expansion card.
