Abstract: This disclosure is directed to a fool-proof structure having a shelf and a plug-in unit. The shelf is defined with a socket and an opening, and a stopping portion and an actuating portion are provided on the socket, and the actuating portion and the stopping portion are respectively communicated to the opening. The plug-in unit has an elastic arm. A stopping wall and an actuating slope of the elastic arm protrude from the plug-in unit. A first pitch is defined from the actuating portion to the stop portion, and a second pitch is defined from the actuating slope to the stopping wall. The first pitch may be configured to be greater than the second pitch, so that the actuating portion may push the actuating slope to deflect the elastic arm before the stopping wall arrives the stop part when the plug-in unit is inserted into the socket.

Abstract: This disclosure is a power supply device including a device body, a fan assembly, an illuminated handle assembly and shock-absorbing fastening elements. The fan assembly is combined in the device body and includes a bracket and a fan, and the bracket includes through holes. The illuminated handle assembly includes a handle, an electrical connecting element, and light-emitting elements. The handle is combined on the bracket and attached to the light-emitting element. The light-emitting element is electrically connected to the electrical connecting element. Each shock-absorbing fastening element is disposed in the fan assembly by each through hole to fix the light-emitting element on a side of the bracket facing the handle. The power supply device controls the light-emitting element through the electrical connecting element. Therefore, the vibration and noise generated during the operation of the fan assembly are reduced, and a power supply device combined with an illuminated handle is provided.

Abstract: A power supply unit supplies power to a load, and the power supply unit includes a power factor corrector, a DC conversion module, and an isolated conversion module. The power factor corrector is plugged into a first main circuit board and converts an AC power into a DC power. The DC conversion module is plugged into the first main circuit board and converts the DC power into a main power. The isolated conversion module includes a bus capacitor, the bus capacitor is coupled to the DC conversion module through a first power copper bar, and coupled to the power factor corrector through a second power copper bar. The first power copper bar and the second power copper bar are arranged on a side opposite to the first main circuit board, and are arranged in parallel with the first main circuit board.
