The generator junction box, serving as a bridge between protection equipment and power supply, has received widespread attention.

[0003] The existing double-sided inlet junction box CN02270357.8 solves the problem of difficult lead wire connection in existing motor junction boxes and is suitable for fixing the lead wires of ordinary pole-changing speed-regulating asynchronous motors and high-power frequency conversion speed-regulating asynchronous motors. This junction box can also be used for DC traction motors in radial bogie locomotives, but it has shortcomings. Existing equipment usually requires workers to use tools to tighten screws one by one to fix the wires, which is cumbersome and time-consuming, especially in locomotive maintenance or emergency repair scenarios, making it difficult to meet the need for rapid wiring. At the same time, the stability of the wires fixed in traditional junction boxes is poor; vibrations during locomotive operation can easily cause the wires to loosen, posing a risk of poor contact and affecting the normal operation of the motor. Therefore, a locomotive motor junction box that allows for rapid wiring is needed to solve the above problems. Utility Model Content
