The existing 19-inch chassis crossbeams are directly tapped on aluminum profiles, resulting in damaged and stripped threads, which affects assembly space and increases costs. In addition, the numerous puller clip holes lead to high machining costs.

Method used

The design incorporates nut strips within the slide rails, connecting the small panel, upper crossbeam, and lower crossbeam with non-detachable bolts. This avoids directly tapping the upper and lower crossbeams. Furthermore, the use of aluminum profiles and multi-point bolt connections reduces height requirements and material costs.

Benefits of technology

Increase assembly space, reduce material and production costs, improve stability and assembly accuracy, reduce thread damage and stripping, and reduce machining costs.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic equipment, in particular to a novel 19-inch machine case crossbeam. BACKGROUND

[0002] With the rapid development of science and technology, in the communication, electronic and other industries, cabinets are widely used in various application occasions. Various products are more and more comprehensive in function, and higher requirements are put forward for the performance of the cabinet. As an important part of the cabinet, the plug-in box plays a crucial role in the whole cabinet system. The plug-in box is composed of a box body, a single board and a module. The single board and the module are inserted into the plug-in box through the guide rail and are connected with the connector of the back plate of the plug-in box. When the single board or the module is completely connected with the box body, the small panel of the single board and the module can be fixed on the crossbeam of the plug-in box by screws. In order to increase the pulling force of the single board and the module, a puller is needed to be installed, which plays a more convenient and quick installation and disassembly role. In the design of the plug-in box, the crossbeam plays a role of limiting and fixing the single board or the module. Therefore, the structure of the crossbeam needs to consider the bearing capacity, production process, space cooperation and cost factors. The crossbeam of the plug-in box is usually made of aluminum profile. The aluminum profile is the preferred choice for the crossbeam of the cabinet in terms of strength, production process and appearance. At present, in the design of the plug-in box, the crossbeam of the aluminum profile still has the factors of mutual restriction among structure, process and cost. For example, in terms of structure, due to the hardness characteristics of the aluminum material itself, if the tapping is directly performed on the aluminum crossbeam, the thread will be damaged after the single board or the module is installed and disassembled for many times, and the phenomenon of thread galling will be caused. Therefore, in order to avoid directly tapping on the aluminum crossbeam, a nut strip hole needs to be opened on the aluminum beam, which will have a minimum requirement for the height of the crossbeam, and affect the reduction of the assembly space. The increase of the material will also directly affect the increase of the cost. At present, the crossbeams used in the industry are mostly 19-inch server standard products, which have a deep depth and are not conducive to the user to insert and pull the board card. At the same time, in order to adapt to the slot width of 5.08mm*N, the puller clamping hole on the crossbeam is as many as 168, and the machining cost is high. SUMMARY
