Multilayer expansion card buffer bracket

Abstract

The invention discloses a multilayer expansion card buffer bracket. The buffer bracket comprises an elastic base, a first support plate and a plurality of second support plate in sequence from bottomto top, wherein the first support plate is fixedly connected with the elastic base; the first support plate is connected with the second support plates in a sliding manner; the adjacent second supportplate are connected in a sliding manner; the elastic base comprises a bottom plate and a fixed plate; a guide pillar is arranged on the bottom plate; a guide sleeve matched with the guide pillar is arranged on the fixed plate; outer side of the guide sleeve is sleeved by a spring; and a rubber buffer pad is arranged at the lower end of the guide sleeve. The buffer bracket not only can satisfy themounting demands of multilayer expansion cards, but also can be adjusted in real time according to distance between adjacent expansion cards so as to facilitate the mounting.

Description

technical field [0001] The invention relates to server hardware equipment, in particular to a multi-layer expansion card buffer bracket for preventing expansion cards from being bumped and deformed in an application server. Background technique [0002] The expansion card is inserted into the PCI-E slot to play the expansion function. Such as Figure 9 As shown in FIG. 2 , the general expansion card is installed in the chassis of the server chassis, one end is fixedly connected to the chassis, and the other end is suspended in the air. During packaging, transportation and bare metal handling, the server is at risk of falling and being impacted, and the expansion card is easily bent and deformed by impact or vibration, resulting in failure and damage of the expansion card. Therefore, adding an appropriate strengthening support device to assist in supporting the expansion card can effectively protect the expansion card and reduce the risk of failure. [0003] At present, sim...

AI Technical Summary

Problems solved by technology

[0004] First, there is no buffer structure, so that it can also protect the expansion card to a certain extent when it is subject to vibration, but when it is impacted or strongly Cards are more prone to damage and failure

[0005] Second, with the rapid development of electronic components, the installation density of electronic components in the chassis is increasing, often appearing as Figure 9 The installation method shown is that the multi-layer expansion cards are stacked and installed in the chassis, but most of the traditional brackets can only fix a single layer, which cannot meet the support requirements of the multi-layer expansion cards.
