ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a positioning structure for motor's pole, and more particularly to a pole of an outer pole type heatsink fan, wherein the positioning structure may be assembled easily, and may prevent misplacement of the pole.
2. Description of the Related Art
A conventional heatsink fan structure in accordance with the prior art shown in
FIG. 7
is disclosed in the applicant's Taiwanese Patent Publication No. 382412, comprising a base board
90
having a shaft
91
for supporting an impeller
92
to rotate. The outer periphery of the blades
93
of the impeller
92
is combined with a magnet ring
94
. The base board
90
is provided with multiple poles
95
for fixing winding coils
97
, and an outer frame
96
is mounted on the base board
90
. The magnet ring
94
may induce with the coils
97
of the base board
90
, so that the impeller
92
may be rotated, and the blades
93
may drive the air to flow.
In the conventional impeller structure, each of the coils
97
is wound respectively to form a unit. After the unit of the coil
97
is fixed on the pole
95
respectively, the terminal of the coil
97
may be connected outward. However, the connection work of the terminal of the coil
97
is more inconvenient, and easily causes misconnection of polarity.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a positioning structure for motor's pole, wherein the pole may be wound with a conducting wire rapidly and conveniently.
A secondary objective of the present invention is to provide a positioning structure for motor's pole, wherein when the pole is mounted on the housing, the positioning structure may be assembled easily, and may prevent misplacement of the pole.
In accordance with the present invention, there is provided a positioning structure for motor's pole including a housing provided with a pivot portion having a periphery provided with multiple wall plates and a pair of insertion seats. Each of the insertion seats is formed with an insertion groove for insertion of a circuit board. The housing is provided with multiple combination posts. The pole includes a magnetically conducting material, and an insulating material. The magnetically conducting material is enclosed by the insulating material, and is partially exposed outward from the insulating material. The magnetically conducting material is wound with a conducting wire.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
