[embodiment]
Consult Fig. 3,4, one preferred embodiment of the stator apparatus 4 of the utility model motor, suitable being installed on the fan 3, this fan 3 includes the central siphon 32 that a shell block 31, is fixedly arranged on these shell block 31 centers, and an impeller 33 that is arranged at rotationally on this central siphon 32.
This preferred embodiment includes a stator seat 41, four stator coils 42, a circuit board 43, and four fixtures 44.In the present embodiment, be meant the aspect when being installed on a computer heat radiation fan especially, certainly when reality is implemented, present embodiment also can be installed in the different systems, for example turbine, domestic electric fan etc., the scope that can use is very extensive, so should not be limited to the explanation of present embodiment.
This stator seat 41 has insulating frame 45 on, insulating frame 46, an and silicon steel sheet 47 that is folded between this upper and lower insulating frame 45,46 once.This upper and lower insulating frame 45,46 all is made by non-conductive materials such as plastic cement, and have 451,461, four of the circumferential collar of central siphon 32 that are set in this fan 3 respectively by this outward extending rib 452,462 in collar 451,461 periphery quartering positions, and four is connected and is surrounded on these collar 451,461 outer rims respectively with corresponding rib 452,462 center on sheet 453,463.
Each stator coil 42 is made by metal material (normally copper cash), each stator coil 42 has a coil body 421 that is wound on the corresponding rib 452,462 of this upper and lower insulating frame 45,46, and one by the stretched lead-out wire 422 of this coil body 421.
This circuit board 43 is sides that are positioned at this stator seat 41, and is worn fixing by this central siphon 32 simultaneously.Each fixture 44 is made by conductive material such as metals, and be inserted in this time insulating frame 46 on the sheet 463, with so that this circuit board 43 and stator coil 42 forms is electrically connected, this circuit board 43 also can form by electric wire and external power source (figure does not show) and be electrically connected, and then makes these four stator coils, 42 energization excitations and produce magnetic field.
Because this upper and lower insulating frame the 45, the 46th is made by nonconducting material, so the electric current of this four stator coil 42 is blocked around sheet 453,463 by each, only remaining magnetic force still can pass each around sheet 453,463 generation effects, and by producing magnetic and repel each other, and then promote this impeller 33 rotations with being located at magnet ring 331 in this impeller 33.
Cooperate and to consult Fig. 4 and Fig. 5, each fixture 44 has a canned paragraph 441, the length nose section 442 less than these canned paragraph 441 length, and a linkage section 443 that connects both corresponding end.Each of this time insulating frame 46 all has a Plug Division 464 around 463, this Plug Division 464 is that depression is provided with a groove 466, this groove 466 is to be arranged at intervals with two perforations 465, and this two perforation 465 is can to stretch through with nose section 442 for the canned paragraph 441 of corresponding fixture 44 respectively.
When described fixture 44 was inserted in corresponding Plug Division 464, these linkage section 443 lucky contacts were lived the bottom of this groove 466, continued to move and touch this circuit board 43 to avoid this nose section 442.
The other end of this canned paragraph 441 is to be welded on this circuit board 43 and with these circuit board 43 formation to be electrically connected, the other end of this nose section 442 be protrude in this time insulating frame 46 outside the sheet 463, do not touch this circuit board 43, and fixing with lead-out wire 422 welding of corresponding stator coil 42.By the above mode, each fixture 44 just can be used as the electrical connecting element of this circuit board 43 and stator coil 42, and the electric current of this circuit board 43 is delivered to this four stator coil 42 via each fixture 44, and then makes these four stator coils, 42 generation magnetic fields and promote this impeller 33 rotations.
Conclude above-mentionedly, the stator apparatus 4 of the utility model motor can effectively improve this circuit board 43 and stator coil 42 and come off with fixture 44 easily and lose the problem that is electrically connected.On the one hand be that be designed to by the Plug Division 464 with this time insulating frame 46 can be in order to canned paragraph 441 and the nose section 442 that plugs corresponding fixture 44, on the other hand, then be to utilize this canned paragraph 441 and nose section 442 apart from one another by separating, making this canned paragraph 441 be welded in this circuit board 43 and form is electrically connected, this nose section 442 is then fixing with lead-out wire 422 welding of corresponding stator coil 42, because it is fixing that this canned paragraph 441 and nose section 442 all only are subjected to once welding, welding heat is still not enough so that the contact portion of described fixture 44 and Plug Division 464 forms the gap because of high heat fusing.Therefore when described stator coil 42 and circuit board 43 by each fixture 44 during with aforesaid mode solder bond, just can effectively improve Welding Structure, and then avoid as the conductive base pin 125 of fan 1 be subjected to the fixing action of twice welding, the high heat conduction of twice welding causes these Connection Block 122 melted by heating and causes and this conductive base pin 125 fixing hypodynamic problems, so can reach the purpose of this utility model really.
