Specific embodiment
Concrete structure of the present utility model is carried out the explanation of detail below in conjunction with accompanying drawing 2-6:
A kind of circuit board of electric fan is pegged graft and is used fixed structure, on shell block 1, be provided with the sense cell 22 of detecting magnet ring 31 change in polarity, ring side in the pin-joint part 11 of shell block 1 is provided with several magnetic poles 12 spaced apart, it is characterized in that: the ring side in the pin-joint part 11 of shell block 1 also is provided with a pair of positioning seat 13 that plugs circuit board 2, sense cell 22 be installed in circuit board 2 in the regional location nearest by the magnet ring detected 31, the lead 23 on the circuit board 2 is to pass in set lead slotted eye 14.Referring to Fig. 2 to Fig. 5.
Positioning seat 13 be arranged on shell block 1 pin-joint part 11 the ring side two magnetic poles 2 and by in the regional location of the nearest sides adjacent of the magnet ring detected 31.Referring to Fig. 2 to Fig. 5.
Positioning seat 13 is provided with the corresponding caulking groove 131 that plugs mutually with limit, circuit board 2 two ends 21.Referring to Fig. 2, Fig. 3.
What lead slotted eye 14 was arranged on shell block 1 plugs circuit board 2 one side margin places.Referring to Fig. 2, Fig. 5.
Lead slotted eye 14 is perforation shapes that a border seal and center connect.Referring to Fig. 2, Fig. 4.
Lead slotted eye 14 is one to piece together the slotted eye that is fastened as by upper and lower two-part, its lower half portion is arranged on the shell block 1 and is the Qian shape groove 141 that chip on a top, pieces together the upper half part of detaining mutually with Qian shape groove 141 and then is arranged on a briquetting 142 with cap 4 corresponding parts of shell block 1 buckle closure.Referring to Fig. 5, Fig. 6.
Working procedure of the present utility model is as follows: shell block 1 has a pin-joint part 11, this pin-joint part 11 can be central shaft or center hole, can articulate rotation for rotor 3 by this pin-joint part 11, on the shell block 1 of these pin-joint part 11 all sides, be provided with and count the magnetic pole 12 that is assemblied on the column 15, be wound with the lead of certain number of turn on this magnetic pole 12, after connecting power supply, this magnetic pole 12 can produce different alternating magnetic fields, the formed magnetic force in this magnetic field can with permanent magnet rings 31 repulsion mutually of rotor 3, to drive the rotation of rotor 3.
See also Fig. 3, shown in Figure 4, it is of the present utility model in conjunction with situation, circuit board 2 by its two ends limit, 21 intercalations in two positioning seats, the 13 set caulking grooves 131 of shell block 1, because this sense cell 22 is designed in preposition, therefore, this sense cell 22 can be positioned at permanent magnet rings 31 proximal most position with rotor 3, in order to detect the change in polarity of this permanent magnet rings 31, and its circuit board 2 set leads 23 can the pile warp positioning seat 13 and passed through by lead slotted eye 14, when this lead 23 is pullled, because this lead 23 through the dual turnover of lead slotted eye 14 and positioning seat 13, makes this lead 23 be difficult for being avulsed by its contact place.
