Embodiment

Hereinafter with reference to correlative type, a kind of fan according to preferred embodiment of the present invention is described, wherein components identical will be illustrated with identical reference marks.

Please refer to shown in Fig. 2 A and Fig. 2 B, a kind of fan 2 of preferred embodiment of the present invention comprises a fan frame 21 and a plug 22.Fan 2 can be a tube-axial fan, and the periphery of fan frame 21 has a holding part 211 and two fixing holes 212, and fixing hole 212 is arranged at the both sides of holding part 211.In the present embodiment, those fixing holes 212 are arranged at the relative both sides of holding part 211, but not as limit.

Fan plug 22 comprises that one has the terminal base 221 of at least two convergence parts 222, a upper pedestal 221a and a lower base 221b; Convergence part 222 is arranged at the both sides of terminal base 221; And be coupled to the fan frame 21 fixing hole 212; Make terminal base 222 be placed in this holding part 211; And one or two utmost point blade type terminals 223 are arranged between upper pedestal 221a and the lower base 221b; Wherein the aperture of fixing hole 212 greater than or slightly equal the size of these convergence parts 222; In order to can when assembling, make the convergence part 222 of corresponding fixing hole 212 designs can snap in smoothly fixing hole 212

Interference when the degree of depth of fixing hole 212 causes with system assembles greater than the length of these convergence parts 222 outward with the convergence part 222 outstanding fan frames after avoiding installing.Shape ovalize, circle or the polygon of fixing hole 212 and the shape of convergence part 222 are corresponding to be designed to oval column, circular cylindrical shape or polygon column, but not subject to the limits.

Convergence part 222 is formed in one and makes with the upper pedestal 221a (shown in Fig. 3 A and Fig. 3 B) or the lower base 221b (shown in Fig. 2 A and Fig. 2 B) of terminal base 221.The width of terminal base 221 is slightly less than the width of this holding part 211, can make terminal base 221 snap in holding part 211 smoothly.

Fan of the present invention again more comprises a motor 23, motor 23 is electrically connected with one or two utmost point blade type terminals made from conductive material 223, upper pedestal 221a and this lower base 221b all respectively have a perforation O, can make a retaining element D wear the perforation O of upper pedestal 221a and lower base 221b, with terminals of a unit block seat 221 with grip two utmost point blade type terminals 223, retaining element D is a screw or a latch, but not subject to the limits.And when convergence part 222 is positioned at upper pedestal 221a, retaining element D is penetrated by the perforation O of lower base 221b earlier, wear upper pedestal 221a again and be positioned between the two two utmost point blade type terminals 223 (as Fig. 3 A with clamping, shown in Fig. 3 B), again plug 22 is snapped in holding part 211 at last and finish assembling, on the contrary, when convergence part 222 is positioned at lower base 221b, retaining element D is penetrated by the perforation O of upper pedestal 221a earlier, wear lower base 221b again and be positioned between the two two utmost point blade type terminals 223 (as Fig. 2 A with clamping, shown in Fig. 2 B), again plug 22 is snapped in holding part 211 at last and finish assembling.

From the above, a kind of fan of the present invention, it makes a fan frame and a plug winding by the convergence part of plug and the structure setting of terminal base, produces the disappearance of interfering when quick assembling function not only being provided and can avoiding existing lead group to assemble.Be compared to and commonly use fan, fan of the present invention cooperates the splicing ear of external system, accurately is electrically connected with external system so can guarantee fan, and then promotes the reliability that is electrically connected.

The above only is an illustrative, but not is restricted person.Anyly do not break away from spirit of the present invention and category, and, all should be contained in the accompanying Claim its equivalent modifications of carrying out or change.
