摘要: A fan frame includes a housing (10), a supporting base (20) and a plurality of ribs (30) connecting the housing with the supporting base. One of the ribs includes a bottom wall (33), and first and second lateral walls (31, 32) extending from two opposite sides of the bottom wall, respectively. A receiving groove (35) is defined between the bottom wall and the lateral walls. A securing tab (40) extends from an outer end of the first lateral wall towards the second lateral wall. A securing finger (42) extends aslant from a free end of the tab towards the second lateral wall. A slot (50) is defined between the finger and the second lateral wall with a width thereof gradually decreased inwardly. The tab, the finger, the bottom wall and the first lateral wall cooperatively define a gap (45) therebetween for extension of power wires (60) of the fan.

摘要: A cooling fan includes a fan housing (30) having a central tube (34) extending upwardly therefrom; the central tube has a bottom, annular protrusion (31). A bearing (61) is received in the central tube and mounted on the protrusion. A stator (20) is mounted around the central tube. A rotor (10) includes a shaft (18) having a free end (186) extending through the bearing and defining a notch (184) therein. A locking washer (63) engages into the notch of the shaft to limit movement of the shaft along an axial direction thereof. A balance structure (62) is arranged between the locking washer and the bearing. The balance structure is made of magnet and exerts a downwardly pulling force on the shaft to prevent the rotor from moving upwardly when the rotor is rotated.
