Fan frame

A cooling fan with power wires, comprising:

• a housing comprising an outer flange;
• a supporting base arranged at one side of the housing;
• and
• a first rib and at least a second rib connecting the outer flange with the supporting base, the first rib defining a receiving groove adapted for retaining the power wires in the receiving groove, an elongated securing finger extending inwardly from the outer flange, a slot being defined between the securing finger and the first rib, the slot communicating with the receiving groove and having a width gradually decreased for guiding the powers wires into the receiving groove from the slot, the width of the slot being gradually decreased inwardly along a length of the securing finger from a portion of the outer flange from which the securing finger extends to an outmost free end of the securing finger.

A fan frame for an electric fan, the fan frame comprising:

• a housing;
• a supporting base arranged at one side of the housing;
• and
• a plurality of ribs connecting the housing with the supporting base, one of the ribs comprising a bottom wall, and first and second lateral walls extending upwardly from two opposite lateral sides of the bottom wall, respectively, a receiving groove being defined between the bottom wall and the first and second lateral walls, a securing tab extending from an outer end of the first lateral wall towards an outer end of the second lateral wall, a securing finger extending aslant and inwardly from an end of the securing tab towards the second lateral wall, a slot being defined between the securing finger and the second lateral wall with a width of the slot gradually decreased inwardly, the securing tab, the securing finger, the bottom wall and the first lateral wall cooperatively defining a gap therebetween adapted for extension of power wires of the fan;
• wherein a distance is defined between an outer end of the bottom wall and a free end of the securing finger for allowing the power wires to enter the gap from the slot;
• and
• wherein a chamfered surface is formed at the outer end of the bottom wall for guiding the power wires into the gap from the slot.
