Power line assembly and motor

The power line assembly comprises an insulating protective shell, a first connecting terminal and a power line, the insulating protective shell is provided with a containing cavity and a terminal groove communicated with the containing cavity, the first connecting terminal is arranged in the terminal groove and is suitable for being connected with a contact pin of the motor in an inserted mode, one end of the power line is connected with the first connecting terminal, and the other end of the power line is connected with the terminal groove. And the power line passes through the accommodating cavity from the first connecting terminal and extends out of the insulating protective shell. By arranging the first connecting terminal to realize connection with the contact pin, power supply to the motor can be realized through the power line assembly, and on the basis, by arranging the insulating protective shell, isolation of the first connecting terminal is realized, a certain electrical safety distance is ensured,
