Further, the connecting bolts comprise vertical connecting bolts and horizontal connecting bolts.

Furthermore, the connecting bolt is a hexagon bolt.

Further, all the waterproof joints are arranged at the bottom in the junction box in parallel.

Furthermore, the junction box is also provided with mounting lugs in an integrated forming mode.

Furthermore, the mounting lug is provided with a threaded mounting hole.

Compared with the prior art, the utility model has the advantages of it is following:

(1) the utility model provides a brand-new wiring device in motor terminal box through the increase to original terminal box, simplifies former wiring device's structure, makes inside leave more sufficient space to be convenient for the wiring.

(2) The utility model discloses a simplification to wiring device to and the suitable enlarged processing of terminal box size. The high-power motor originally is enabled to be thick and not easy to bend, the space is short when the number of cables is large, and the condition that wiring is inconvenient is effectively improved.
