A backflow prevention device includes at least one backflow prevention unit. The backflow prevention unit includes a frame, a first edge shutter plate, a second edge shutter plate and plural intermediate shutter plates. The frame includes an airflow channel. If the first inner sidewall is disposed over the second inner sidewall, the first edge shutter plate and the plural intermediate shutter plates are configured to open or close the airflow channel, and the slab of the second edge shutter plate is inactive. Whereas, if the second inner sidewall is disposed over the first inner sidewall, the second edge shutter plate and the plural intermediate shutter plates are configured to open or close the airflow channel, and the slab of the first edge shutter plate is inactive.

Backflow prevention device and fan assembly

A case structure includes a first housing and a fan frame fixing module. The fan frame fixing module includes a fan frame, a positioning part and an auxiliary part. The positioning part is disposed on the first housing. The auxiliary part is disposed on the first housing. The fan frame urges against the first housing and the positioning part, and the auxiliary part urges against the fan frame so that the fan frame is fixed on the first housing.

Case structure and fan frame fixing module

An electronic device includes a circuit board and a power connection interface. The power connection interface is formed on an edge region of the circuit board. The power connection interface includes a first trace portion for transmitting a DC voltage and second and third trace portions for transmitting an AC voltage. Plural trace wires of the first trace portion are arranged on first and second surfaces of the edge region. The second and third trace portions are arranged on opposite surfaces of the edge region.

Electronic device having power connection interface

An electronic device swappable to be embedded into a system cabinet includes a casing and a locking element. The casing includes a first sidewall and a second sidewall, which have a first opening and a second opening, respectively. The locking element includes a first end part, a protrusion part, a bent part and a second end part. The first end part is fixed on an inner surface of the second sidewall of the casing. The protrusion part is partially exposed from the second opening to be engaged with a receiving structure of the system cabinet. The bent part is arranged between the first end part and the protrusion part. The second end part is exposed from the first opening so as to be protruded from the first sidewall of the casing.

Swappable electronic device having locking element

A power supply apparatus for use with a redundant power supply system includes a casing, a main circuit board and an airflow driving device. The casing includes a first airflow opening and a second airflow opening. The main circuit board is disposed within the casing and includes plural electronic components thereon. The airflow driving device is disposed in the middle region of the main circuit board. A cooling air is pumped by the airflow driving device to be introduced into the inner portion of the casing through one of the first airflow opening and the second airflow opening, then the heat generated from the electronic components is removed by the cooling air, and finally a heated air is exhausted through the other one of the first airflow opening and the second airflow opening.

Power supply apparatus

A redundant power supply system includes a system cabinet, a first power supply apparatus, a second power supply apparatus and a power converting circuit board. The system cabinet at least includes a first receptacle and a second receptacle. The first power supply apparatus has a first connection interface. The second power supply apparatus has a second connection interface. The power converting circuit board is disposed inside the system cabinet and includes a first insertion slot, a second insertion slot and a power converting circuit. A voltage outputted from the first power supply apparatus and/or the second power supply apparatus is converted by the power converting circuit into a regulated voltage when the first connection interface of the first power supply apparatus and the second connection interface of the second power supply apparatus are inserted into the first insertion slot and the second insertion slot, respectively.
