Detailed ways

The implementation of the present utility model is illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification.

See Figure 1. It should be noted that the structures, proportions, sizes, etc. shown in the drawings attached to this specification are only used to match the content disclosed in the specification, for those who are familiar with this technology to understand and read, and are not used to limit the implementation of the utility model Therefore, it has no technical substantive meaning. Any modification of structure, change of proportional relationship or adjustment of size shall still fall within the scope of The technical content disclosed by the utility model must be within the scope covered. At the same time, terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description and are not used to limit this specification. The practicable range of the utility model, and the change or adjustment of its relative relationship, without any substantial change in the technical content, shall also be regarded as the practicable scope of the utility model.

As shown in Figure 1, the utility model provides a sheet metal bus bar power supply structure, including a main board 1, a power supply frame 2 and a power backplane 3 connected to the power supply frame 2, wherein: the main board 1 and the power backplane The plates 3 are connected by at least one sheet metal bus bar 4 .

Specifically, the power supply frame 2 is used to accommodate a power supply, and the power supply backplane 3 is installed on one side of the power supply frame 2 . In this embodiment, the power backplane 3 and the mainboard 1 are vertically arranged, and there is an insulating layer 6 between the power backplane 3 and the mainboard 1, and the insulating layer 6 is used to prevent human hands from Enter the 4 that comes across the sheet metal bus bar.

Specifically, the sheet metal bus bar 4 includes a body 41 and a pair of side wings 42 connected to both ends of the body 41. The pair of side wings 42 are respectively in contact with the main board 1 and the power supply backplane 3, and pass through Fasteners hold.
