Embodiment Construction

[0017] Please refer to FIG. 6; FIG. 6 is a schematic diagram of the power system 5 of the present invention. Different from the prior art, the expansion sub-board 40 of the power supply system 5 includes two voltage output ports 42, 44, two voltage input ports 41, 43 and two conductive plates 46, 48. The voltage output port 42 and the voltage input port 41 are simultaneously connected to the The conductive plate 46 , and the voltage output port 44 and the voltage input port 43 are simultaneously connected to the conductive plate 48 . In addition, the power supply lines 22, 24 are also connected to the voltage input ports 41, 43, respectively.

[0018] If a USB electronic device is suddenly inserted into the voltage output port 42 , the instantaneous voltage drop caused by the insertion action will not directly affect the voltage level of the voltage output port 44 . Because the phenomenon of instantaneous voltage drop will pass through the conductive plate 46, the power line ...

Abstract

This invention relates to one power system, which comprises one host board, one extensive board and one cable wire, wherein, the host board is connected to the extensive board through cable wire; the board multiple voltage output terminals output same voltage calibration to separate the power supply path and to connect the separate power supply path by use of multiple power lines to reduce the interference between output terminals.

Description

technical field [0001] The invention relates to a power supply system, in particular to a power supply system capable of reducing mutual interference of multiple voltage output ports on an expansion sub-board. Background technique [0002] Generally speaking, some slots for input and output ports, such as USB ports, are reserved on the casing of the computer to connect external electronic devices at any time. These reserved input and output port slots are usually integrated on a daughter board, and the daughter board is connected to the mother board through a cable. [0003] Take the USB slot as an example. Usually there are two USB slots on the computer shell. The output voltage levels of the two USB slots are the same. Usually, the power supply of the two USB slots is supplied on the expansion daughter board. Connect together with the same power plane or power trace. When a USB electronic device is connected to one of the USB slots and the USB electronic device is in ope...
