A thermal module includes a centrifugal fan (20) and a fin unit (30). The centrifugal fan includes a casing (21) and a rotor (22) received in the casing. The casing defines an air outlet (24) through which an airflow generated by the fan flows, the air outlet having a front side outlet section (24a), a rear side outlet section (24b) and a central outlet section (24c) between the front side outlet section and the rear side outlet section. The fin unit includes a plurality of fins arranged across the air outlet of the fan. The fins arranged at the front side outlet section and the rear side outlet section of the air outlet have a longer length than the fins arranged at the central outlet section of the air outlet.

A thermal module (100) includes a centrifugal blower (10) including a base plate (142), a top cover (16) and a sidewall (144) disposed between the base plate and the top cover and defining two air outlets (148a, 148b) therein; two fin assemblies (20a, 20b) are disposed at the air outlets of the centrifugal blower; two heat pipes (30, 40) are thermally connected with the fin assemblies and stacked along a height direction of the thermal module, which is substantially perpendicular to the base plate of the centrifugal blower. Each of the heat pipes thermally connects with a corresponding electronic component for transferring heat of the two electronic components to the two fin assemblies to be dissipated to ambient air.

An electronic device includes a panel, a button assembly, and a circuit board. The panel defines an opening. The button assembly is mounted to the rear surface of the panel, and includes a button partially received in the opening of the panel, a base plate fixed to the rear side of the button, and a substantially U-shaped balance bar. The button includes a push portion and two protrusions rearwards extending through the base plate. An end of the balance bar is movably connected to the rear side of the base plate, and an opposite end of the balance bar is pivotably connected to the protrusions of the button. The circuit board is fixed behind the button assembly, and includes a switch aligning with the push portion of the button. When the button is pressed, the balance bar restricts the button to just move linearly to the switch.

An electrical connector system includes a substrate (1) connected to PHY side and an electrical connector (3) mounted on the substrate (1), a transformer (5) and a common mode filter (7). The electrical connector (3) is used to mate with a cable assembly and so forms a Cable side. The transformer (5) further includes a first wire (51) having two opposite ends electrically connected to the PHY side and a second wire (53) having two opposite ends. The common mode filter (7) has a third wire (73) and a fourth wire (75) physically separated from the second wire (53). The third wire (73) has an end electrically connected to one end of the second wire (53) and an opposite end electrically connected to the Cable side. The fourth wire (75) has an end electrically connected to the opposite end of the second wire (53) and an opposite end electrically connected to the Cable side.

A centrifugal fan includes a fan frame (20) and a fan impeller (10) received in the fan frame. The fan impeller includes a hub (12) and a plurality of fan blades (14) extending radially from an outer periphery of the hub. Each of the fan blades has a leeward lateral surface (144a) and an opposite windward lateral surface (144b) as the fan impeller rotates. At least one of the fan blades has a rib (146) protruding longitudinally and outwardly from the leeward lateral surface of the fan blade. The rib is located adjacent to an outmost free end of the fan blade and adapted for blocking an airflow generated by the fan impeller to flow back towards the fan blades of the fan impeller.
