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 Fig. 2 A, 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, these fixing holes 212 are arranged at the relative both sides of holding part 211, but not as limit.

Fan plug 22, comprise that one has a base 221 of at least two convergence parts 222, convergence part 222 is arranged at the both sides of base 221, and be connected to the fan frame 21 fixing hole 212, make plug 22 be placed in the holding part 211 of this fan frame 21, fan plug 22 comprises that more one or two utmost point blade type terminals 223 are arranged on the base 221 and between two

convergence parts

222, and 224 on a gland is to utilize the snapping mode to combine with base 221 with clamping two utmost point blade type terminals 223.

Wherein the aperture of fixing hole 212 is greater than the size of these convergence parts 222, so that can when assembling, make the convergence part 222 of corresponding fixing hole 212 designs can snap in fixing hole 212 smoothly, and the interference of the degree of depth of fixing hole 212 when causing with system assembles greater than the length of convergence part 222 outward with the convergence part 222 outstanding fan frames after avoiding installing, fixing hole 212 ovalizes, circle or polygonal hole, convergence part 222 ovalize columns, circular cylindrical shape or the polygon column of corresponding design, but not subject to the limits.Convergence part 222 is made of one piece with the base 221 of pedestal 221, and gland 224 also is one of the forming with base 221 and makes.The width of base 221 is the width that are slightly less than this holding part 211 in addition, can make plug 22 snap in holding part 211 smoothly.

Fan of the present invention again more comprises a motor 23, motor 23 is electrically connected with drive fan with one or two utmost point blade type terminals made from conductive material 223, and gland 224 is connected by a turning point C between the two with base 221, gland 221a has a perforation O, 221 of bases have the shank D that an end comprises a hook portion D1, after two utmost point blade type terminals 223 place going up of base 221, deflection bending by turning point C, the hook portion D1 hook of shank D is established in the perforation O that is sticked in the position correspondence, two utmost point blade type terminals 223 are clamped in form plug 22 between gland 224 and the base 221 (as Fig. 3 A, Fig. 3 B, Fig. 4 A, shown in Fig. 4 B).

From the above, its convergence part 222 by plug 22 of a kind of fan of the present invention, the structure setting of base 221 make fan frame 21 and a plug 22 windings, produce the disappearance of interfering in the time of quick winding function not only can being provided and can avoiding existing lead group 11 to assemble.Be compared to existing fan 1, fan 2 of the present invention can cooperate the attachment plug 22 of external system, accurately electrically connects so can guarantee fan 2 and external system, and then promotes the reliability that is electrically connected.
