Description

Technical Field

[0001] This utility model relates to the field of server accessories, and in particular to an auxiliary fixing bracket for a PCIe card, and a server. Background Technology

[0002] A PCIe card (PCI Express card) is a network interface card with a PCIe interface, primarily used for motherboard-level connections as an expansion port. PCIe-based cards can be inserted into PCIe slots on the motherboards of devices such as hosts, servers, and network switches. PCIe cards are an important component of computer and server hardware, used to expand or enhance computer functionality. This design allows users to customize and upgrade their computer systems according to their needs by installing different PCIe cards. The main uses of PCIe cards include improving computer display performance, audio quality, network connection speed, and storage capacity. For example, adding a dedicated graphics card enhances display performance, and adding a dedicated sound card improves audio quality. In addition, PCIe cards also include network cards, SAS cards, and RAID cards.

[0003] PCIe cards are typically rectangular in shape, with gold fingers on one long side and a hand-tightening screw on one short side (the edge adjacent to the gold fingers). They are used to connect to the sheet metal parts of computer and server chassis. When installed in the chassis, the gold fingers are inserted into the corresponding slots on the motherboard, and the hand-tightening screw is connected to the chassis. Based on this, the two-sided fixing structure of the PCIe card is formed.

[0004] Considering the durability of the gold fingers and the need for repeated insertion and removal, the connection between the gold fingers and the motherboard slot is usually not used as the primary load-bearing structure. Excessive friction and a tight fit between the gold fingers and the slot are also avoided. Therefore, after a PCIe card is installed in the chassis, one long side and one short side are suspended in the air, and the long side containing the gold fingers does not provide significant stability.

[0005] During transportation and handling, servers are at risk of being impacted or even dropped. PCIe cards may vibrate relative to the chassis. On the one hand, this vibration can easily cause the gold fingers to loosen and deform the gold fingers and slots. On the other hand, since one short side of the PCIe card is firmly fixed, vibration may also cause the PCIe card to bend and deform, resulting in excessive local stress and strain, which can damage the PCIe card. Summary of the Invention

[0006] This invention addresses the problem that PCIe cards, when installed in computer and server chassis using existing connection methods, are prone to loosening of the gold fingers or even damage when the chassis is subjected to impact. It provides an auxiliary fixing bracket for PCIe cards that can enhance the fixing effect of PCIe cards.

[0007] To solve the above problems, the technical solution adopted by this utility model is an auxiliary fixing bracket for a PCIe card, including a connecting component. The connecting component is L-shaped and includes a horizontal section and a vertical section. The vertical section is located at the first end of the horizontal section. The lower end of the vertical section is provided with a connecting slot. The opening of the connecting slot is horizontally arranged and faces the second end of the horizontal section. The connecting slot is used to fix the edge of the PCB board of the PCIe card.

[0008] This solution cleverly utilizes the inherent structure of the PCIe card itself, namely the edge of the PCIe card's PCB board, to design an auxiliary bracket. This bracket is installed in the chassis and connects to the PCIe card's cable connector via a connecting slot. It is then connected to the chassis via a cantilever, ensuring that one pair of opposite sides of the PCIe card are connected. This, combined with the gold fingers, forms a three-sided fixed structure. When the chassis is subjected to impact, the fixed ends greatly reduce the vibration of the PCIe card and prevent deformation. At the same time, the two adjacent edges of the gold fingers are fixed, preventing loosening and improving connection stability.

[0009] As a preferred implementation of the auxiliary fixing bracket for PCIe cards, the connecting assembly includes a cantilever rod and a PCB board connector. The PCB board connector is installed at the first end of the cantilever rod. The PCB board connector is L-shaped and includes a flat plate and a vertical plate. The flat plate is connected to the first end of the cantilever rod, and the flat plate and the cantilever rod form the horizontal section of the connecting assembly. A connecting slot is provided at the lower end of the vertical plate.

[0010] The connection components adopt a split structure, with one part connecting to the chassis and the other to the PCB board. This allows the cantilever to be installed on the chassis first, and then the PCB board connectors to be installed according to the position of the PCIe card, making installation more convenient.

[0011] As a preferred embodiment of the auxiliary mounting bracket for PCIe cards, it also includes a mounting base, with the second end of the cantilever connected to the side of the mounting base. The bracket is connected to the chassis via the mounting base, creating a larger connection area, further improving the bracket's installation stability and enhancing the fixation effect on the PCIe card.

[0012] As a preferred embodiment of the auxiliary mounting bracket for PCIe cards, multiple sets of cantilever arms and PCB board connectors are provided on the mounting base, and each cantilever arm is detachably connected to the mounting base. This allows for flexible configuration of the corresponding number of cantilever arms and PCIe card mounting components based on the number of PCIe cards installed in the chassis.

[0013] As a preferred implementation of the auxiliary fixing bracket for PCIe cards, the second end of the cantilever is provided with a connecting plate, which is perpendicular to the cantilever. The connecting plate is provided with a first fixing hole and a second fixing hole. The side of the mounting base is provided with a positioning post and a threaded hole. The positioning post corresponds to the position of the first fixing hole and is connected to it. The threaded hole corresponds to the position of the second fixing hole and is fitted with a locking screw. The locking screw passes through the second fixing hole and is threadedly connected to the threaded hole.

[0014] As a preferred embodiment of the auxiliary mounting bracket for PCIe cards, a reinforcing rib is provided at the inner corner between the cantilever and the connecting plate. This increases the overall rigidity of the cantilever and makes it less prone to vibration and bending.

[0015] As a preferred embodiment of the auxiliary mounting bracket for PCIe cards, the first end of the cantilever rod is provided with a dovetail groove, and the cross plate of the PCB board connector is provided with a dovetail tenon, which engages with the dovetail groove. The cantilever rod and the PCB board connector are connected by the dovetail groove and the dovetail tenon, resulting in high connection rigidity, strong torsional resistance, and ensuring support strength.

[0016] As a preferred embodiment of the auxiliary fixing bracket for PCIe cards, the horizontal plate of the PCB board connector is further provided with a locking post, and the cantilever rod is further provided with a locking hole, with the locking post engaging with the locking hole. This length-direction limiting prevents the connecting slot from sliding and loosening, improving the connection effect.

[0017] As a preferred embodiment of the auxiliary mounting bracket for PCIe cards, the mounting base is provided with at least two chassis connection holes, which are countersunk holes. After the mounting base is installed, the connecting bolts are embedded in the countersunk holes, reducing positional interference with external PCIe cards and other structures.

[0018] On the other hand, this utility model also provides a server, including a PCIe card module, the PCIe card module including a module bracket, a PCIe card installed in the module bracket, the tail end of the PCIe card being fixedly connected to the module bracket; the aforementioned auxiliary fixing bracket is installed at the front position of the module bracket, and the connecting slot in the auxiliary fixing bracket of the PCIe card is connected to the edge of the PCB board of the PCIe card.

[0019] As can be seen from the above technical solutions, the advantages of this utility model are as follows: This solution designs an auxiliary fixing bracket for PCIe cards, which, in conjunction with the original installation structure of the PCIe card in the chassis, further fixes one of its suspended short sides, forming a three-sided fixation, improving the installation stability of the PCIe card in the chassis, and preventing damage to the PCIe card due to vibration under impact. At the same time, fixing is achieved on both sides of the gold fingers, improving the stability of the gold finger insertion and preventing loosening and poor contact. The fixing bracket cleverly utilizes the PCB board of the PCIe card, clamping and fixing it from above through the connecting card slot, occupying little space and facilitating installation. The fixing bracket itself has a reasonable structural design, high strength, and is easy to assemble, providing a good fixing effect for the PCIe card. Therefore, the server provided by this utility model has the aforementioned auxiliary fixing bracket for PCIe cards, ensuring stable installation of the PCIe card inside the chassis, better impact resistance, and ensuring more stable operation of the server.
