Abstract
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.
