Electric connection method for motor stator and coil of motor stator

Abstract

An electric connection method for a motor stator and a coil of the motor stator is used for achieving a good positioning effect during coil welding and comprises the steps that an iron core and the coil are prepared, the coil is combined with the iron core in a wound mode, and at least one wiring part is pulled and led out from the coil in advance; a circuit board is prepared, and a prearranged welding part and an adhesion positioning part are arranged on the circuit board in advance; the wiring part of the coil is positioned on the adhesion positioning part of the circuit board in an adhesive mode, and then the wiring part of the coil is combined with the prearranged welding part of the circuit board in a welded mode so that the coil can be in electric connection with the circuit board through the wiring part. According to the structural design, the circuit board matched with the motor stator is provided with the adhesion positioning part, and therefore the effects of improving the assembly quality of the coil and the circuit board, reducing cost and the like can be achieved.

Description

technical field [0001] The invention relates to a motor stator and its coil electrical connection method, in particular to a method for electrical connection with a circuit board after the coil is pre-positioned, and a motor stator with the coil positioning structure. Background technique [0002] The Chinese patent application No. 201110277390.3 "Cooling fan and assembly method thereof" discloses a conventional motor structure applied to a cooling fan. Please refer to figure 1 , the existing motor 9 roughly includes a base 91 , a motor stator 92 and a motor rotor 93 . The base 91 is provided with a shaft tube 911; the motor stator 92 is combined with the outside of the shaft tube 911, and the motor stator 92 has an iron core 921, a coil 922 and a circuit board 923, and the iron core 921 is used for the coil 922 to be wound Combined, the coil 922 is electrically connected to the circuit board 923; the motor rotor 93 is rotatably combined with the shaft tube 911; thereby, t...

[0005] Or, in order to make the wiring portion 922a of the coil 922 accurately align with the predetermined welding position on the circuit board 923 during welding, some related companies will additionally use various positioning fixtures to position the wiring of the coil 922 before welding. part 922a to facilitate the electrical connection between the coil 922 and the circuit board 923, but when using various positioning fixtures to position the coil 922 during the welding process, it is easy to generate many unnecessary costs, such as: increase The cost of manufacturing and using the positioning jig; and the inconvenience caused by the assembly personnel to use the positioning jig for positioning, resulting in redundant manpower and time costs; or, in the assembly process of a general micro motor, the circuit board 923 is generally After being combined with the base 91 in advance, the welding operation of the wiring portion 922a of the coil 922 is performed, so that the positioning jig must be used in conjunction with the base 91, so the structural design of the positioning jig must consider how to cooperate with the positioning jig. If the base 91 cooperates, there may even be a situation where they cannot cooperate with each other; therefore, the above-mentioned method of using a positioning jig for positioning is actually not in line with economic benefits
