In one implementation scenario, with the development of the ABC (AI, Big Data, Cloud) technology, processing operation, deep learning, AI analysis, and the like on Big Data, the operation capability of the CPU cannot meet the demand, and the operation capability of the GPU well solves the problem of insufficient operation capability of the CPU, thereby implementing functions such as machine learning and computer vision.

Referring to fig. 1, in a current application scenario, a GPU module is generally vertically placed in a chassis, a GPU card 10 of the GPU module is in a vertical state, when the GPU module is installed, a gold finger 101 is inserted into a connector 301 on a bottom plate 30, and a clamping mechanism 40 is inserted into a sheet metal part of the chassis, so that the GPU module is fastened through a screw 20.

Because the installation is vertical, golden finger 101 and connector 301 cooperation of GPU module are closely, when GPU module work produced the vibration, because the weight of GPU module acts on connector 301 perpendicularly, transmit on bottom plate 30, can not cause too big injury to golden finger 101 and connector 301.

However, as AI is applied to various communication devices, the GPU module application scenario becomes more complex, and the GPU module needs to be placed in a narrow space, and the GPU module needs to be placed horizontally due to the limitation of the height and size of the GPU module, please refer to fig. 2.

At this time, the GPU module is in a suspended state. Influenced by the weight of the GPU module, when the equipment vibrates, the vibration amplitude of the suspended part of the unfixed GPU module is large, so that the vibration amplitude of the whole GPU card is increased, and further the golden finger 111 and the connector 311 are influenced inevitably to be influenced by the vibration of the GPU module, so that damage is caused, and the performance of the equipment is influenced.

The GPU is only one of the plug-in cards, different plug-in cards with multiple functions can be realized in the case, the plug-in cards can face the situation that part of the plug-in cards are in a suspension state, once the equipment works to generate vibration, the suspension part can face larger vibration amplitude to further influence the stability of the connecting piece of the equipment and the case, and the contact connection between the plug-in cards and the case is influenced to further influence the performance of the equipment. This effect may be referred to as a floating effect. Simultaneously, unsettled influence can appear when not only plug-in card horizontal installation, and unsettled influence also can appear in vertical the placing of plug-in card. For the case of full card insertion into the chassis, the unsupported portion in the middle may also face the floating effect.
