Abstract
The utility model relates to a stator combining device for a small-sized radiating fan, which comprises a circuit board and a coil holder, wherein, the circuit board can be combined with each electronic piece, the central hole of the circuit board is used for a central shaft pipe of the coil holder to pass through, and a plurality of positioning holes are inserted and crossed by metal posts of the coil holder; the coil holder is provided with a plurality of metal posts which can be wound with one end of a metal wire and can be extended out of the circuit board to conduct a power supply, and the metal posts are welded on the circuit board to form the fixed combination of the coil holder and the circuit board.
Description
The utility model relates to a kind of stator coupling apparatus of small heat-dissipating fan.
Office equipment such as computer, photoprinter, during use owing to easily produce high temperature, therefore being equipped with the small heat-dissipating fan is dispelled the heat, and the stator component of this small heat-dissipating fan is usually with a circuit board and coil holder be combined into, and the metal wire of coil holder again by the set breach of circuit board around more, fixing by the scolding tin welding again, so comparatively trouble and inconvenience on making.In No. 221590 " stator structure of radiator fan " of bulletin, its circuit board promptly is provided with breach and supplies the metal lead wire of coil around the another side that is welded on circuit board more, and establish some pilot holes on the circuit board again, pass through for the setting element on the coil holder, be fixed on the chassis again, the metal lead wire wiring of this coil comparatively bothers, and circuit board must be established breach again and supply metal lead wire around getting over except that establishing some pilot holes.
The purpose of this utility model is to provide a kind of stator coupling apparatus of small heat-dissipating fan, it can make the lead-in wire wiring operation of coil comparatively convenient, and circuit board does not also need to establish breach again, makes the wiring of whole stator and combination comparatively simple, rapid, and reduces fraction defective.
The purpose of this utility model is to realize like this, a kind of stator coupling apparatus of small heat-dissipating fan promptly is provided, it comprises a circuit board and a coil holder, on the described circuit board in conjunction with the Electronic Control part, and be provided with a center pit that passes through for the central shaft tube of described coil holder and supply the pilot hole of described coil holder combination with several, described coil holder is provided with the central shaft tube that passes through and become position rotating for the rotating shaft of rotor, is wound with metal wire on the described coil holder; Described coil holder is provided with several metal columns of being made by conductive material, respectively twines an end of a metal wire on it, described metal column closely insert pull in the pilot hole of described circuit board and pass through by and connect with power supply.
The advantage of the utility model device is that simple in structure, assembly working is more rapid, convenient, and reduces fraction defective greatly
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:
Fig. 1 is a three-dimensional exploded view of the present utility model;
Fig. 2 is a combination front elevation of the present utility model;
Fig. 3 is a top view of the present utility model.
See also shown in Figure 1ly, the utility model is made of circuit board 1, coil holder 2.
This circuit board 1 can be fixing for various Electronic Control part welding, it passes through with the central siphon 21 of a center pit 11 for coil holder 2, and pass through with the metal column 22 of several pilot holes 12 for coil holders 2, and the two available mode combination that closely cooperates, weld with scolding tin again and fixed.
This coil holder 2 can be made by non-conductive materials such as plastic cement, it is provided with a central shaft tube 21, can pass through for the rotating shaft 31 of rotor 3, and one-tenth position rotating, this coil holder 2 is provided with several metal columns 22, it is made with conductive material, can be one-body molded when coil holder 2 is penetrated system, or after making, followed closely coil holder 2 system again, when on the coil holder 2 behind volume metal wire 23, the terminal of metal wire 23 can respectively be around in wherein on the metal column 22, and each metal column 22 can be plugged in the pilot hole 12 of pulling in circuit board 1, and pass through protrusion (as shown in Figure 2) outside circuit board 1, connect power lead to draw.
See also shown in Fig. 2,3, after circuit board 1 and coil holder 2 are finished separately, metal column 22 direct the inserting of coil holder 2 are formed on the pilot hole 12 of circuit board 1 and pass through protrusion outside circuit board 1, the solder joint that will design on metal column 22 that volume has a metal wire 23 and circuit board 1 with scolding tin is welded again, make its jail inseparable, then can connect by power supply, and it is fixing that coil holder 2 is combined with circuit board 1 by the metal column 22 that protrudes.
In sum, the utility model can be after the coil holder coiling be finished, be wrapped in the metal wire of drawing on the metal column easily, and can connect by power supply by metal column, so can on circuit board, supply metal wire around getting over by machining gap, and it is more rapid that the work of being pulled that makes power lead becomes, convenient, and the metal column that metal wire is arranged around volume is after the scolding tin welding is fixing, promptly finish coil holder and combining of circuit board and connecting of power lead and metal wire simultaneously, work than the metal wire that is pulled between circuit board and coil holder after the existing apparatus combination is more convenient, reduce fraction defective rapidly, and greatly.
