Description

Technical Field

[0001] The utility model relates to the field of modular power supplies, in particular to a modular power supply. Background Art

[0002] The connector on legacy modular power supplies typically attaches the modular housing to a small board, which is then attached to the mainboard. This creates a connection impedance between the modular housing and the small board, and also between the small board and the mainboard. Because the connector is attached to the small board, the modular cable must be routed before connecting to the mainboard. Furthermore, the mainboard is mounted horizontally within the housing, leaving the small board vertical, forcing the connector jacks to be located on the side of the power supply housing. During wiring, field personnel must flip the power supply over to visually align the cables with the connectors. Because the mains power connector and the computer connector are often located at opposite ends of the power supply housing, the power supply must be rotated 180 degrees for wiring. Frequent rotation of the power supply poses a risk of cable breakage.

[0003] Therefore, a modular power supply is proposed, which is convenient for observing interfaces and wiring. Utility Model Content
