The wiring areas include a head wiring cavity 101 and a tail wiring cavity 102 respectively arranged at both ends of the wiring rack 1. The power connection component includes a wiring row 2 penetrating the wiring rack 1 and threaded fasteners 3 respectively arranged at both ends of the wiring row 2. Both ends of the wiring row 2 are respectively connected to the head wiring cavity 101 and the tail wiring cavity 102, and a filling part integrally formed with the wiring rack 1 is arranged in the middle of the wiring row 2.

[0022] Such as Figure 5As shown, in actual application, the head wiring cavity 101 is usually located outside the controller 10 to facilitate the wiring connection between the head wiring board and the external circuit, while the tail wiring cavity 102 is arranged in the sealed controller 10 to facilitate the wiring connection between the tail wiring board and the controller 10 circuit.
