Description

Slide rail assembly

technical field

The invention relates to a slide rail assembly, in particular to a slide rail assembly suitable for at least two cabinets and convenient for pulling the at least two cabinets apart from each other.

Background technique

In a general rack server system, slide rails are mostly installed on both sides of the server chassis (chassis), and are erected on the support columns of the rack (rack) by means of the slide rails and their brackets, so that the server can be pulled out. Out of the rack, which is convenient for inspection and maintenance. The design of related sliding rails has been disclosed in US Patents U.S. 7,137,512, U.S. 6,930,886, etc., which are incorporated herein for reference. At present, for the convenience of maintenance and disassembly, different parts and components of the server have been modularized. For example, a host module is installed in the middle of the chassis, and hard disk modules and power modules are installed at both ends of the chassis, and the modules are connected to each other by wires. When detaching each module (for example: a hard disk module), you need to unplug the lines between the modules first, but because the lines in the chassis are complicated and the space is small, the lines are not easy to be unplugged, so there are still many inconveniences in maintenance.
