摘要
A system chassis may comprise a frame having a width, depth, and height and a plurality of divider walls coupled to the frame and forming a plurality of receptacles each configured to receive an electronics tray containing an electronic assembly. Each of the plurality of divider walls comprises a metal sheet having a front edge, a back edge, and two lateral edges, the two lateral edges attached to two lateral walls of the frame. The front edge of the metal sheet has a concave shape such that a distance between the front edge and the back edge of the metal sheet continuously decreases while moving laterally from one lateral edge to a center of the front edge and continuously increases while moving laterally from the center to the opposite lateral edge.

Some electronic systems comprise a plurality of electronic devices (e.g., servers, networking devices, power supply units, etc.) that are housed together within a shared mechanical enclosure, referred to as a system chassis. Each of these electronic devices comprises an electronic assembly (e.g., a system board with a processor and memory, etc.) and a mechanical supporting structure or enclosure that supports and/or houses the electronics assembly, which may be referred to herein as an electronic assembly tray. The electronic assembly trays may be received within corresponding slots or receptacles in the system chassis.
One or more divider walls are often included in the system chassis. The divider walls help to define the slots or receptacles into which the electronic assembly trays are received, with the divider walls being positioned as separators between the individual electronics assembly trays when the trays are assembled into the system chassis. The divider walls may aid in supporting the electronic assembly trays as well as provide signal isolation between the electronic assemblies. The divider walls are usually attached to two opposing lateral sides of the system chassis, and sometimes the divider walls are also attached to a back side of the system chassis. However, the divider walls are generally not attached to the system chassis along the front side thereof—the front of the system chassis is often left relatively open to allow for unimpeded insertion of trays. The divider walls may be constructed out of sheet metal, such as steel, and the divider walls may be relatively thin in order to limit their weight and the amount of space they occupy, as well as their cost.
