[0002] With the rapid development of industrial technology, the requirements for the performance, efficiency and safety of motors, as key components for driving various mechanical equipment, are also constantly increasing. As an important part of the motor, the design of the junction box directly affects the convenience, safety and maintenance efficiency of the motor.

[0003] Traditional motor junction boxes usually adopt a fixed design, that is, the position and angle of the junction box are fixed, which to a certain extent limits the flexibility of use and convenience of maintenance of the motor. For example, in certain installation environments of the motor, the wiring port on the junction box faces inward. At this time, when wiring, the cable needs to be bent before it can be connected to the interface line on the junction box. As a result, the fixed junction box may cause the wires or cables to bend, twist or even break, thereby affecting the normal operation of the motor. Utility Model Content
