The main body has a securing tab (30) extending from an outer surface thereof. The securing tab has a free end. A groove (32) for the wires to extend through is defined between the securing tab and the outer surface of the main body. At least a block (35) extends from the outer surface of the main body. A space (80) for receiving the wires therein is defined between the block, the securing tab and the outer surface of the main body. A guiding surface (352) is formed on the block from a bottom end towards a top end of the block for guiding the wires to move into the space. ## Claims ### Claim 1 A fan frame for an electric fan, comprising: a main body with conducting wires being secured thereon; a securing tab extending outwardly from a first side of an outer surface of the main body, the securing tab having a free end being spaced from the main body, a groove for extension of the wires therethrough being defined between the securing tab and the outer surface of the main body; a block extending outwardly from a second side opposite to the first side of the outer surface of the main body, cooperatively the block, the securing tab and the outer surface of the main body defining a space for receiving the wires, a guiding surface being formed on an outer surface of the block for guiding the wires into the space, a top end of the block being located above a lower end of the securing tab. ### Claim 2 (depends on 1) The fan frame of claim 1, wherein a securing arm extends from the main body along an axial direction thereof, the block being formed on an outer surface of the securing arm. ### Claim 3 (depends on 2) The fan frame of claim 2, wherein the securing tab and the block are spaced from each other along a circumferential direction of the main body, the block forms a holding surface connecting with the outer surface of the securing arm at the top end of the block. ### Claim 4 (depends on 3) The fan frame of claim 3, wherein the holding surface is of a shape selected from the group consisting of triangle-shaped and semicircle-shaped. ### Claim 5 (depends on 3) The fan frame of claim 3, further comprising a second block formed on the securing arm, the two blocks being respectively arranged on two opposite sides of the securing tab. ### Claim 6 (depends on 2) The fan frame of claim 2, wherein a hook is formed on an inner surface of the securing arm for engaging with a heat dissipation apparatus to assemble the fan frame thereon. ### Claim 7 (depends on 2) The fan frame of claim 2, wherein a slot is defined in the securing arm corresponding to a position of the securing tab. ### Claim 8 (depends on 2) The fan frame of claim 2, wherein the securing tab extends outwardly from the main body and then is bent perpendicularly downwardly. ### Claim 9 (depends on 1) The fan frame of claim 1, wherein the guiding surface is one of slant-shaped and curve-shaped. ### Claim 10 (depends on 1) The fan frame of claim 1, further comprising a retaining tab for securing the wires thereon, the retaining tab extending outwardly from the main body along a circumferential direction of the main body, a groove being defined between the retaining tab and the main body for extension of the wires therethrough. ### Claim 11 A fan frame for an electric fan, comprising: a round main body with conducting wires being secured thereon; a securing arm extending from the main body along an axial direction thereof; a securing tab extending outwardly from a first side of an outer surface of the main body, the securing tab having a free end being spaced from the main body, a groove for extension of the wires therethrough being defined between the securing tab and the outer surface of the main body; a block extending outwardly from an outer surface of the securing arm at a position below the first side of the outer surface of the main body; and a holding surface being formed at an end of the block near the securing tab and extending from the outer surface of the securing arm, cooperatively the holding surface of the block, the securing tab and the outer surface of the main body defining a space receiving the wires. ### Claim 12 (depends on 11) The fan frame of claim 11, wherein a guiding surface is formed on an outer surface of the block for guiding the wires to move into the space, the guiding surface is one of slant-shaped and curve-shaped. ### Claim 13 (depends on 11) The fan frame of claim 11, wherein the holding surface is one of triangle-shaped and semicircle-shaped. ### Claim 14 (depends on 11) The fan frame of claim 11, further comprising a second block formed on the securing arm, the two blocks being respectively arranged on two opposite sides of the securing tab. ### Claim 15 (depends on 11) The fan frame of claim 11, wherein a slot is defined in the securing arm corresponding to a position of the securing tab. ### Claim 16 A fan frame of an electronic fan comprising: a main body adapted for receiving a stator and a rotor of the fan therein; first and second securing arms extending downwardly from the main body, each having a hook adapted for securing the main body to a heat dissipation device; a resilient retaining tab circumferentially extending from the main body and above the first securing arm, wherein a first groove is defined between the retaining tab and the main body; a resilient securing tab extending downwardly from the main body toward the second securing arm, wherein a second groove is defined between the securing tab and the main body and between the securing tab and the second securing arm; a guiding block protruding from the second securing arm toward the securing tab, the guiding block having an outer guiding surface; and at least a wire having a first end adapted for securing to the fan and a second end adapted for connecting with a power source, the at least a wire extending through the first and second grooves, the guiding surface guiding the at least a wire into the second groove. ### Claim 17 (depends on 16) The fan frame of claim 16, wherein the main body is round in shape and a section of the at least a wire adjacent to the second end thereof is received in the first groove. ### Claim 18 (depends on 16) The fan frame of claim 16, wherein the block has a holding face at an upper end thereof, for preventing the at least a wire for escaping the second groove. ### Claim 19 (depends on 18) The fan frame of claim 18, wherein the holding face extends horizontally and outwardly from the second securing arm and comprises one of following shapes: triangle and semicircle. ### Claim 20 (depends on 18) The fan frame of claim 18, wherein the outer guiding surface has one of following shapes: slant and curve.
