Detailed ways

A fan according to a preferred embodiment of the present invention will be described below with reference to related drawings, wherein the same components will be described with the same reference symbols.

Referring to FIG. 2A and FIG. 2B , a fan 2 according to a preferred embodiment of the present invention includes a fan frame 21 and a plug 22 . The fan 2 can be an axial fan. The fan frame 21 has a receiving portion 211 and two fixing holes 212 on the periphery of the fan frame 21 . The fixing holes 212 are disposed on both sides of the receiving portion 211 . In this embodiment, the fixing holes 212 are disposed on opposite sides of the accommodating portion 211 , but it is not limited thereto.

The fan plug 22 includes a terminal base 221 having at least two connecting parts 222, an upper base body 221a and a lower base body 221b. The terminal base 222 is accommodated in the accommodating portion 211, and a two-pole blade terminal 223 is disposed between the upper base body 221a and the lower base body 221b, wherein the diameter of the fixing hole 212 is greater than or slightly equal to that of the engaging portions 222. size, so that the connecting portion 222 designed corresponding to the fixing hole 212 can be smoothly snapped into the fixing hole 212 during assembly,

The depth of the fixing hole 212 is greater than the length of the engaging portions 222 to prevent the installed engaging portions 222 protruding out of the fan frame and interfering with the system assembly. The shape of the fixing hole 212 is elliptical, circular or polygonal, and the shape of the connecting portion 222 is correspondingly designed as an elliptical column, circular column or polygonal column, but not limited thereto.

The connecting portion 222 is integrally formed with the upper body 221a (as shown in FIGS. 3A and 3B ) or the lower body 221b (as shown in FIGS. 2A and 2B ) of the terminal base 221 . The width of the terminal base 221 is slightly smaller than the width of the accommodating portion 211 , so that the terminal base 221 can be smoothly inserted into the accommodating portion 211 .

The fan of the present invention further includes a motor 23, the motor 23 is electrically connected to a two-pole blade terminal 223 made of conductive material, the upper base body 221a and the lower base body 221b each have a through hole O, which can make a fixed The element D passes through the through hole O of the upper base body 221a and the lower base body 221b to combine the terminal base 221 and clamp and fix the two-pole blade terminal 223. The fixing element D is a screw or a pin, but not limited thereto. And when the connecting portion 222 is located on the upper base body 221a, the fixing element D first penetrates through the perforation O of the lower base body 221b, and then penetrates the upper base body 221a to clamp the two-pole blade terminal 223 between them (as shown in the figure 3A and 3B), and finally snap the plug 22 into the accommodating part 211 to complete the assembly. On the contrary, when the connecting part 222 is located at the lower seat body 221b, the fixing element D is first penetrated through the through hole O of the upper seat body 221a, The lower seat body 221b is then pierced to hold the two-pole blade terminal 223 between them (as shown in FIG. 2A and FIG. 2B ), and finally the plug 22 is snapped into the accommodating portion 211 to complete the assembly.

Based on the above, a fan according to the present invention, through the structural arrangement of the connecting part of the plug and the terminal base, the fan frame is assembled with a plug, which not only provides a quick assembly function but also can avoid interference when the existing wire group is assembled missing. Compared with the conventional fan, the fan of the present invention cooperates with the connection terminal of the external system, so it can ensure the accurate electrical connection between the fan and the external system, thereby improving the reliability of the electrical connection.
