Power extending board and power supply system using same

摘要

A power supply system includes a power source and a power extending board detachably connected between the power source and an electronic device. The power source includes at least two outputs. The power extending board includes at least two first transmitting terminals and a second transmitting terminal connected to the two first transmitting terminals. Each of the two outputs transmits a first driving voltage from the power source to the second transmitting terminal via a corresponding first transmitting terminal. The first driving voltages from the power source are identical to each other. The second transmitting terminal transmits a second driving voltage to the electronic device. The second driving voltage is identical to each of the first driving voltages.

主权项

1. A power extending board, comprising:
at least two first transmitting terminals configured to detachably connect to at least two outputs of a power source and receive first driving voltages from the power source via the at least two outputs, the first driving voltages being identical, each of the at least two first transmitting terminals outputting a first driving voltage; a first grounded terminal configured to connect to ground via a first ground terminal of the power source; a second transmitting terminal connected to the at least two first transmitting terminals, and configured to connect to an input of an electronic device, the second transmitting terminal receiving the first driving voltages from the at least two first transmitting terminals, and outputting a second driving voltage to the electronic device via the input, the second driving voltage being identical with each of the first driving voltages; and a second ground terminal connected to the first ground terminal of the power extending board, and configured to connect to a ground terminal of the electronic device.
