Joint locking part, joint sliding rail, joint and case

Abstract

The invention discloses a joint locking part, a joint sliding rail, a joint and a case. The joint locking part is arranged in the joint sliding rail, and comprises a support rod, a sliding block arranged at one end of the support rod and an opening part arranged on the sliding rail, wherein the support rod moves towards the opening part along the extension direction of the sliding rail, the sliding block enters the opening part, and the opening part extends from nicks in the upper and lower sides of the joint sliding rail; the support rod moves away from the opening part along the extension direction of the sliding rail, the sliding block is separated from the opening part, and the opening part is retracted into the joint sliding rail. When the support rod of the joint locking part moves towards the opening part along the extension direction of the sliding rail, the opening part extends from the nicks in the joint sliding rail, and contacts with a sliding way on the inner wall of a case body, so that a gap between the joint sliding rail and the sliding way on the inner wall of the case is eliminated, and a function of bearing the weight of the joint is realized.

Description

technical field [0001] The embodiment of the present invention relates to mechanical technology, in particular to a node locking component, a node slide rail, a node and a cabinet. Background technique [0002] In products such as minicomputers or high-end servers, it is often necessary to install blades or nodes with large volume and heavy weight. During transportation, the nodes are subject to vibrations and impacts, which may easily damage the connectors used to connect the nodes and the chassis, and even interrupt server communication. [0003] In a large frame or cabinet server structure, in order to compensate for system tolerances and ensure that nodes can be inserted and removed smoothly in the chassis, it is necessary to ensure that the upper and lower sides of the slideways have a gap greater than 1 mm, while the gap between the guide pins of the connector is 0.2 mm on one side. mm, the guide pin guide sleeve is fixed on the printed circuit board (PCB) by screws, ...

AI Technical Summary

Problems solved by technology

During transportation, the node is subject to vibration and impact, which may cause the connector used to connect the node and the chassis to be easily damaged, and even the communication of the server may be interrupted.

[0003] In a large frame or cabinet server structure, in order to compensate for system tolerances and ensure that nodes can be inserted and removed smoothly in the chassis, it is necessary to ensure that the upper and lower sides of the slideways have a gap greater than 1 mm, while the gap between the guide pins of the connector is 0.2 mm on one side. mm, the guide pin guide sleeve is fixed on the printed circuit board (PCB) by screws, so after the node is inserted into the backplane, the weight of the node is transferred to the PCB, which increases the risk of damage to the PCB due to force
