However, in the welding process, the corresponding wire sequence of the multi-wire welding is difficult to control, so that the problems of wrong welding and missing welding are easily caused, the motor 200 is failed, and the defective rate is high. And the solder in the welding process is easy to drip and splash on the electric connecting wire 140 bundle or the circuit board 220, which can cause the problem of short circuit on one hand, and on the other hand, in the later working vibration process of the motor 200, the dropped solder can generate abnormal sound in the motor 200, thereby increasing the working noise of the motor 200. In addition, a large amount of labor cost is required for welding operation, and the process is long and not beneficial to efficient production and low-cost production of the motor 200.

And under the condition of ensuring that the relative positions of the first shell 110 and the second shell 130 are correct, the connecting wires 140 of the connecting wires 140 and the windings are correct, and the problem that wrong welding and missing welding are easy to occur in the welding process is solved. And then realized optimizing coupling assembling 100 structure, realized motor 200's modular design, promoted motor 200 production efficiency and yields, reduction in production cost's technological effect.

In addition, this structure allows the connection wire 140 to be detached by releasing the connection relationship between the second housing 130 and the first housing 110. However, in the related art, the power line soldered to the winding cannot be detached during maintenance, which may cause adverse conditions such as interference and shielding for maintenance operation, and the soldered power line may be detached due to pulling during maintenance. The connection assembly 100 of the present application can solve this problem by removing the second housing 130.
