[0069] Here, the connection part 30 is arranged into a strong current connection part 30 and a weak current connection part 30, and the strong current connection part 30 and the weak current connection part 30 are separated, so that the connection personnel can accurately distinguish the strong current connection position and the weak current connection position to prevent wrong connection.

[0070] In some embodiments, the first sink groove 31 of the high-current connection portion 30 is marked with a high-current mark 34 , and the first sink groove 31 of the low-current connection portion 30 is marked with a low-current mark 35 .

[0071] In this embodiment, a strong current mark 34 and a weak current mark 35 are marked on the first sink 31 , so that the wiring personnel can accurately distinguish the wiring positions of strong current and weak current.

[0072] Optionally, the bottom wall of the first sink 31 is marked with a strong current mark 34 and a weak current mark 35. In this way, it is easy for the wiring personnel to find the marks, so as to accurately connect the wires according to the marks. Optionally, the strong current mark 34 is located below the strong current outlet 32, and the weak current mark 35 is located below the weak current outlet 32. In this way, the strong and weak current marks 35 correspond to and are close to the positions of their respective outlets 32, which is easy for the wiring personnel to find, so that the wiring personnel can accurately determine the wiring position.

[0073] In some embodiments, the protrusion 21 further comprises a bottom side wall connected to the lower portion of the rear side wall, and the bottom side wall is provided with a disassembly portion 40, which is configured to disassemble the wires and the terminal 33.
