Description

Technical Field

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

[0002] Expansion cards are essential components of computer and server hardware, used to expand or enhance computer functionality. This design allows users to customize and upgrade their computer systems based on their needs by installing different expansion cards. Expansion cards are primarily used to enhance a computer's display performance, sound quality, network connection speed, and storage capacity. For example, adding a discrete graphics card enhances display performance, or a discrete sound card improves sound quality. Other expansion cards include network cards, SAS cards, and RAID cards.

[0003] Expansion cards are usually rectangular in structure, with a gold finger on one long side and a hand-tightening bolt on one short side (adjacent to the gold finger). They are used to connect to the sheet metal parts of the computer or server chassis. When installed in the chassis, the gold finger is inserted into the corresponding slot on the motherboard and the hand-tightening bolt is connected to the chassis, thus forming a fixed structure on both sides of the expansion card.

[0004] Considering the durability of the gold finger and the need for repeated insertion and removal, the connection between the gold finger and the motherboard slot is usually not the primary force-bearing structure, and the design of the gold finger and the slot should not have excessive friction or an overly tight fit. As can be seen, after the expansion card is installed in the chassis, one long side and one short side are suspended in the air, and the long side where the gold finger is located does not provide much fixing effect.

[0005] During transportation and handling, the server is at risk of being impacted or even falling, and the expansion card will vibrate relative to the chassis. On the one hand, this vibration can easily cause the gold finger to loosen and the gold finger and slot to deform. On the other hand, the short side of one side of the expansion card is firmly fixed. As a result of the vibration, the expansion card may bend and deform, resulting in local excessive stress and strain, causing damage to the expansion card. Summary of the Invention

[0006] The utility model aims to solve the problem that the gold finger connection of the expansion card is easily loosened or even the expansion card is damaged when the cabinet is impacted when the expansion card is installed in the computer or server chassis using the existing connection method. The utility model provides an expansion card auxiliary fixing bracket that can enhance the fixing effect of the expansion card.

[0007] To solve the above problems, the technical solution adopted by the present invention is an expansion card auxiliary fixing bracket, including a cantilever rod and an expansion card fixing member, the expansion card fixing member is installed below the cantilever rod, and the expansion card fixing member has a connecting bayonet opening downward, and the connecting bayonet is used to fix the cable connector of the expansion card.

[0008] This solution cleverly utilizes the structure of the expansion card itself, that is, a cable connector is set on the edge of the expansion card, and an auxiliary bracket is designed. This bracket is installed in the chassis, and is engaged with the cable connector of the expansion card through the connecting clamp of the expansion card fixing part. It is connected to the chassis through the cantilever part, so that a set of opposite edges of the expansion card are connected, and then combined with the gold finger to form a three-side fixed structure. When the chassis is impacted, the fixation at both ends greatly reduces the vibration of the expansion card and avoids deformation of the expansion card. At the same time, the adjacent edges on both sides of the gold finger are fixed, avoiding loose insertion and improving connection stability.

[0009] As a preferred implementation, it further includes a mounting base, one end of the cantilever rod is connected to the side surface of the mounting base, and the expansion card fixing member is installed on the cantilever rod near the other end.

[0017] The expansion card fixing part can be moved along the cantilever rod to adjust the position, and can adapt to different cable connector positions on different expansion cards; at the same time, it is fixed with hand screws, which makes installation and tightening convenient and fast.

[0018] As a preferred implementation, the vertical plate includes an outer plate and a slide plate. An opening is provided at one end of the outer plate, and the slide plate is inserted into the opening. A tension spring is provided between the insertion end of the slide plate and the inner bottom surface of the opening of the outer plate.
