INSTRUCTIONS: [Technical Field] The present invention relates to a waterproof and dustproof stator assembly for a cooling fan and a manufacturing method thereof, and more particularly to a method that can be easily replaced and used to solve the problem that the power supply wire is detached and cannot be repaired. Fan waterproof and dustproof stator group and its manufacturing method 0 [Prior Art] According to the fact, the cooling fan has its important position in the electronics industry or industry, because the electronic device or industrial machine often generates heat during operation, in order to avoid electrons The device or industrial equipment is damaged by overheating, so a cooling fan is added to assist in heat dissipation. Please refer to the figure 6 in the figure. The existing cooling fan system includes an outer frame (71), a certain sub-group (72) and a blade rotor group (73), wherein the stator group (72) is externally arranged. On the frame (71), the stator assembly (72) is included in a plurality of silicon steel sheets (721), and the upper and lower insulation seats (722) (723) of the Shishi steel sheets (721) are respectively clamped from above and below. And a coil (not shown) wound around the silicon steel sheet (721), and the same circuit board (724) is passed through the shaft seat (711) of the outer frame (71), wherein the silicon steel sheet ( 721) the wound coil is connected to the circuit board (724) through a plurality of pins (725) or directly by wires, and the circuit board (724) is further soldered with a power supply wire (not shown) for connecting the power supply. The blade rotor set (73) is coaxially sleeved outside the stator set (72) for rotation relative to the stator set (72). The fan rotor group (73) includes a ring magnetic strip (731) and a fan blade 4 . 200952578 (732), and the bottom of the blade (732) is provided with a rotating shaft (733), and the ring magnetic strip (731) The rotating shaft (733) is passed through and accommodated in the blade (732) and the rotating shaft (733) further passes through the stator group (72), so that the annular magnetic strip (731) is relatively located The outer side of the silicon steel sheet (72彳) of the stator assembly (72); that is, when the circuit board (724) applies current to the coil of the stator assembly (72), the magnetic pole is generated on the silicon steel sheet (721), and The magnetic poles on the magnetic stripe (731) of the blade rotor group (73) are mutually exclusive, and then the rotor rotor group (73) is rotated by 0 ❹, but the silicon steel sheet (721) in the stator group (72), Once the components on the coil and circuit board (724) are wet, they are prone to rust or short circuit, which causes damage to the cooling fan. To this end, manufacturers have designed a cooling fan with a waterproof stator set. As for the invention patent case No. 28〇322 of China's announcement, please refer to the seventh figure. In order to achieve the effect of dustproof and waterproof, a cover body (81) is integrally formed on the frame body (8〇). And the stator assembly (91) is disposed in the cover body (81), and the bottom plate is further tightly coupled to the cover body (81) by a bottom plate (92) to tightly cover the stator assembly (91). The power supply conductor (911) of the stator set (91) passes through the bottom plate (92) for connection to the operating power source. Since the above power supply lead (911) is only soldered to the stator set (91), once the power supply lead (91彳) is accidentally pulled, the power supply lead (91彳) may be detached from the stator set (91), but due to the stator The group (91) has been tightly wrapped in the cover body =), so the disconnection position between the power supply wire (911) and the stator group (91) has been fitted into the cover body (81) and the bottom plate (92). Therefore, it is impossible to re-weld the power supply wire (1) to the stator group (91); in addition, since the cover body (81) is formed with the frame 200952578 body (80)-body, it is fixed at -, ^ Subgroup, , =) is also equivalent to the frame _ completely fan replaced, the real pole does not meet the economic cost considerations 2: waterproof stator group, must be snowed from the horse, the horse can be used to put the stator and The frame (80) having the lid body (81) has an effect of being placed in the frame body (8 inches) to be brought into close contact with each other to achieve a waterproof effect, so that the cost of the component member is high. ❹ 疋 ‘The existing cooling fan with waterproof stator set is still to be begging and seeking a viable solution.
